Japanese Patent Application Laid-Open No. 2019-53509

However, the invention described in Patent Document 1 above had the problem of not being able to prevent erroneous reporting in cases where a taxpayer files a tax return despite not meeting the applicable period for the special deduction for housing loans, etc., and therefore not being able to receive the deduction.

The present invention was made in consideration of the above-mentioned problems, and aims to provide a housing loan deduction management device, housing loan deduction management method, and housing loan deduction management program that can prevent reporting errors by checking the deduction period when reporting special deductions for housing loans, etc.

To solve the above-mentioned problems and achieve the objectives, the housing loan deduction management device of the present invention is a housing loan deduction management device equipped with a memory unit and a control unit, wherein the memory unit includes a housing deduction table master that links and sets the type of special deduction for housing loans, etc., the specific acquisition category, the period of residence in the home, and the number of years for deduction, and the control unit includes a deduction declaration acquisition means that acquires deduction declaration data that links and sets the date of first residence in the home, the type of special deduction for housing loans, etc., and the specific acquisition category, a deduction determination means that determines whether an application for a special deduction for housing loans, etc., conforms to the deduction application period based on the housing deduction table master and the deduction declaration data, and a warning execution means that executes a warning process if the deduction determination means determines that the application for a special deduction for housing loans, etc., does not conform to the deduction application period.

Furthermore, in the housing loan deduction management device according to the present invention, the deduction determination means determines whether the application for the special housing loan deduction falls within the deduction application period by comparing the number of deduction years with the number of years elapsed since the date of residence in the home, based on the housing deduction table master and the deduction declaration data.

Furthermore, in the housing loan deduction management device of the present invention, the residence period includes a residence period start date and a residence period end date, and the deduction determination means identifies a record in the housing deduction table master that is linked to the type of special deduction for housing loans, etc. and the specific acquisition category set in the deduction declaration data, and determines whether the application for the special deduction for housing loans, etc. conforms to the deduction application period by comparing the number of deduction years set in the record that is linked to the residence period start date and residence period end date that constitute the period including the date of start of residence in the home with the number of years that have elapsed since the date of start of residence in the home.

Furthermore, in the housing loan deduction management device of the present invention, the deduction determination means, based on the housing deduction table master and the deduction declaration data, obtains the number of years elapsed by adding 1 to the number of years obtained by subtracting the year of residence start, including the date of residence start, from the year in which the housing loan special deduction was declared, and determines whether the housing loan special deduction application conforms to the deduction application period by comparing the number of deduction years with the number of years elapsed since the date of residence start.

Furthermore, in the housing loan deduction management device according to the present invention, the warning execution means executes the warning process by displaying an error message when the deduction determination means determines that the housing loan special deduction application does not conform to the deduction application period.

Furthermore, in the housing loan deduction management device according to the present invention, the warning execution means executes the warning process by displaying an error message indicating that the deduction period has expired when the deduction determination means determines that the number of years that have passed exceeds the number of deduction years and that the housing loan special deduction application does not comply with the deduction application period.

Furthermore, in the housing loan deduction management device according to the present invention, the warning execution means further executes the warning process by displaying an error message indicating that year-end tax adjustment is not possible if the number of years that have elapsed since the date of first residing in the home is zero.

Furthermore, in the housing loan deduction management device of the present invention, the deduction declaration acquisition means acquires the deduction declaration data when the date of commencement of residence in the home, the type of special housing loan deduction, etc., and the specific acquisition category are set on the declaration screen, and the warning execution means executes the warning process by displaying the error message on the declaration screen when the deduction determination means determines that the application for the special housing loan deduction, etc., does not conform to the deduction application period.

The housing loan deduction management method of the present invention is a housing loan deduction management method to be executed by a housing loan deduction management device having a memory unit and a control unit, wherein the memory unit includes a housing deduction table master that links and sets the type of special deduction for housing loans, etc., the specific acquisition category, the period of residence in the home, and the number of years for deduction, and the control unit includes a deduction declaration acquisition step executed by the control unit that acquires deduction declaration data that links and sets the date of start of residence in the home, the type of special deduction for housing loans, etc., and the specific acquisition category; a deduction determination step that determines whether the application for special deduction for housing loans, etc., conforms to the deduction application period based on the housing deduction table master and the deduction declaration data; and a warning execution step that executes a warning process if the deduction determination step determines that the application for special deduction for housing loans, etc., does not conform to the deduction application period.

The housing loan deduction management program of the present invention is a housing loan deduction management program to be executed by a housing loan deduction management device having a memory unit and a control unit, wherein the memory unit includes a housing deduction table master that links and sets the type of special deduction for housing loans, etc., the specific acquisition category, the period of residence in the home, and the number of years for deduction, and the control unit executes a deduction declaration acquisition step that acquires deduction declaration data that links and sets the date of residence in the home, the type of special deduction for housing loans, etc., and the specific acquisition category, a deduction determination step that determines whether the application for the special deduction for housing loans, etc., conforms to the deduction application period based on the housing deduction table master and the deduction declaration data, and a warning execution step that executes a warning process if the deduction determination step determines that the application for the special deduction for housing loans, etc., does not conform to the deduction application period.

The present invention has the effect of preventing filing errors and reducing the cost of refiling by checking the deduction period (applicable period) when filing a special deduction for housing loans, etc. (mortgage deduction). Furthermore, the present invention has the effect of reducing filing errors by filers, thereby reducing the cost of checking by administrators. Furthermore, the present invention has the effect of managing the deduction period in master data, allowing for flexible response to future system changes. Furthermore, while year-end tax adjustments require complex content checks and approvals in a short period of time, the present invention has the effect of making combined checks, such as the home purchase date and type of deduction, aware of the employee at the filing stage. Furthermore, the present invention has the effect of checking whether the period is eligible for deduction based on the values entered by the operator and the housing deduction table master, allowing for flexible response to changes in the system that result in increases or decreases in the type of deduction or specific acquisition category. Furthermore, according to the present invention, the applicable period for a home loan varies depending on the filer's type of home loan deduction and the date of commencement of residence. However, by managing various deduction periods in a master and referencing the master data from input data and checking it, filers whose applicable period for the home loan deduction has expired can be warned before they erroneously file a return, thereby reducing erroneous returns by filers and reducing the burden of checking work on administrators. Furthermore, the applicable period for the special deduction for home loans, etc. varies depending on the type of home acquired and the date of commencement of residence. However, according to the present invention, by managing the applicable period for the deduction in a master and checking the deduction period at the time of filing, errors in filing can be prevented.

An embodiment of the present invention will be described in detail with reference to the drawings. However, the present invention is not limited to this embodiment.

[1. Overview]
First, an overview of the present invention will be described with reference to Figures 1 to 5. Figure 1 is a diagram showing an example of a period for special deductions for housing loans, etc. Figures 2 to 5 are diagrams showing an example of a conventional housing loan deduction management process.

During year-end tax adjustments, the period during which you can claim the special deduction for housing loans, etc. is determined by when you began living in the home after purchasing it and the type of deduction. As shown in Figure 1, if you purchase a regular home, the period during which you can claim the special deduction for housing loans, etc. will vary depending on the year you began living in the home.

Here, as shown in Figure 2, traditionally, in order to apply for the special deduction for housing loans, etc. during year-end tax adjustments, data from the deduction certificate received from the tax office in the second year after the deduction began, and the balance certificate received from the bank each year, were required (note that the deduction is applied when filing a tax return in the first year after the deduction begins).

As shown in Figure 3, previously, during the year-end adjustment for the year in which the deduction period ended, the deduction certificates received from the tax office were only issued for the number of years for which the special deduction for housing loans, etc. was available from the second year onwards from the start of the deduction. Therefore, if the taxpayer did not have a deduction certificate on hand, the administrator would determine that the special deduction for housing loans, etc. was not available.

Furthermore, as shown in Figure 4, previously, when multiple housing loan deductions were applied, even if the deduction period for one housing loan deduction (e.g., new construction) had expired, there was a risk that the filer would still have the deduction certificate for the other (e.g., extensions and renovations), which could lead to the filer filing a claim. In other words, previously, if an employee had multiple housing loans, there were cases where they would file a claim for the special housing loan deduction even though the applicable period for the special housing loan deduction had expired.

In addition, as shown in Figure 5, in the past, there were cases where filers with little understanding of the system filed without receiving the deduction certificate from the tax office (cases where they filed their tax return during year-end adjustments even though they were supposed to file their final tax return in the first year the housing deduction was applied), cases where filers received a loan balance certificate from the bank every year but mistakenly believed they were eligible for the deduction in the year it was received and filed incorrectly (cases where filers filed even though the applicable period for the deduction had expired and they were no longer eligible), and cases where filers filed without entering the data from the balance certificate, which placed a burden on administrators in communicating with filers and checking their records.

As a result, the calculation method for the housing loan deduction, even among year-end tax adjustments, was previously complex, leading to many mistakes by filers and creating a heavy burden on administrators for checking. Furthermore, in the past, filers would sometimes file even when the application period for the special housing loan deduction had expired and they were not eligible for the deduction, resulting in incorrect filing. Furthermore, in the past, administrators had to pay costs for checking to prevent incorrect filing.

This embodiment therefore focuses on preventing filers from making erroneous declarations of the special deduction for housing loans, etc., and reducing the burden of checking work on administrators. It provides a system that can flexibly respond to future system reforms by managing the applicable years in master data. In other words, this embodiment provides a system that stores data on the number of deduction years, which varies depending on the type of deduction and the start date of residence, in advance in a master data file. This system checks the contents of the declaration for the special deduction for housing loans, etc., before the filer makes an erroneous declaration outside the applicable period, and references the deduction years in the master data from the registered data on the screen, and if the applicable period for the deduction has passed, a check error is generated (a system that allows the checking logic to be changed by providing master data, even if the housing deduction system changes in future system reforms).

2. Configuration
An example of the configuration of the housing loan deduction management device 100 according to this embodiment will be described with reference to Fig. 6. Fig. 6 is a block diagram showing an example of the configuration of the housing loan deduction management device 100 according to this embodiment.

As shown in FIG. 6, the housing loan deduction management device 100 is a commercially available desktop personal computer. Note that the housing loan deduction management device 100 is not limited to a stationary information processing device such as a desktop personal computer, but may also be a portable information processing device such as a commercially available notebook personal computer, PDA (Personal Digital Assistant), smartphone, or tablet personal computer.

The housing loan deduction management device 100 comprises a control unit 102, a communication interface unit 104, a memory unit 106, and an input/output interface unit 108. Each unit of the housing loan deduction management device 100 is connected to each other so that they can communicate with each other via any communication path.

The communication interface unit 104 communicatively connects the housing loan deduction management device 100 to the network 300 via a communication device such as a router and a wired or wireless communication line such as a dedicated line. The communication interface unit 104 has the function of communicating data with other devices via a communication line. Here, the network 300 has the function of connecting the housing loan deduction management device 100 and the server 200 so that they can communicate with each other, and is, for example, the Internet or a LAN (Local Area Network).

An input device 112 and an output device 114 are connected to the input/output interface unit 108. The output device 114 may be a monitor (including a touch panel), a speaker, or a printer. The input device 112 may be a keyboard, a mouse, a microphone, or a monitor that functions as a pointing device in conjunction with a mouse. Note that, below, the output device 114 may be referred to as the monitor 114 or the printer 114, and the input device 112 may be referred to as the keyboard 112 or the mouse 112.

The memory unit 106 stores various databases, tables, files, and the like. The memory unit 106 stores computer programs that work in conjunction with the OS (Operating System) to issue commands to the CPU (Central Processing Unit) to perform various processes. The memory unit 106 can be, for example, a memory device such as RAM (Random Access Memory) or ROM (Read Only Memory), a fixed disk device such as a hard disk, a flexible disk, or an optical disk. The memory unit 106 includes a deduction type master 106a, an acquisition category master 106b, a housing deduction table master 106c, and a tax database 106d.

The deduction type master 106a is a master that sets the types of special deductions for housing loans, etc.

Here, an example of the deduction type master 106a in this embodiment will be described with reference to Figure 7. Figure 7 is a diagram showing an example of the deduction type master 106a in this embodiment.

As shown in Figure 7, the deduction type master 106a in this embodiment stores classification values, and classification value data is distributed when the system is revised. In this embodiment, the type of special deduction for housing loans, etc., and the period for the special deduction for housing loans, etc., change depending on the type of loan taken out when taking out a mortgage. Here, as shown in Figure 7, "1: Ordinary Home" is a loan taken out when acquiring an ordinary home, "2: Certified Home" is a loan taken out when acquiring a certified home (a home that meets certain requirements), "3: Specific Additions and Renovations" is a loan taken out when making specific additions and renovations (barrier-free access, etc.), and "4: Earthquake, etc." is a loan taken out when re-acquiring a home damaged in the Great East Japan Earthquake.

Returning to Figure 6, acquisition category master 106b is a master that sets the specific acquisition category for home loans.

Now, with reference to Figure 8, an example of the acquisition category master 106b in this embodiment will be described. Figure 8 is a diagram showing an example of the acquisition category master 106b in this embodiment.

As shown in Figure 8, in this embodiment, the acquisition classification master 106b stores classification values, and classification value data is distributed when the system is revised. In this embodiment, the specific acquisition classification changes depending on when and at what consumption tax rate the home was acquired when taking out a mortgage, which in turn changes the period for the special housing loan deduction. As shown in Figure 8, "1: Specific Acquisition" is the classification for homes acquired at an 8% or 10% consumption tax rate (this applies to homes acquired at a 10% rate but with late occupancy), "2: Special Specific Acquisition" is the classification for homes acquired at a 10% consumption tax rate (occupancy by the end of 2021), and "3: Special Special Exceptional Acquisition" is the classification for homes with a floor area of 40 to 50 square meters acquired during a specified period at a 10% consumption tax rate.

Returning to Figure 6, the housing deduction table master 106c is a master that links and sets the type of special deduction for housing loans, etc., the specific acquisition category, the period of residence in the home, and the number of years for deduction. Here, the period of residence in the home may include the start date of the period of residence and the end date of the period of residence. Note that the housing deduction table master 106c is not intended to be changed by the user, and the data in the housing deduction table may be updated by applying the year-end adjustment update program that is distributed every year.

The tax database 106d stores tax data. Here, the tax data may include deduction declaration data, home loan balance certificate data, and/or home loan detail data.

The control unit 102 is a CPU or the like that provides overall control of the housing loan deduction management device 100. The control unit 102 has internal memory for storing control programs such as an OS, programs that define various processing procedures, and required data, and executes various information processing operations based on these stored programs. Functionally, the control unit 102 includes a deduction declaration acquisition unit 102a, a deduction determination unit 102b, a warning execution unit 102c, and a registration unit 102d.

The deduction declaration acquisition unit 102a acquires deduction declaration data for special deductions such as housing loans. Here, the deduction declaration acquisition unit 102a may acquire deduction declaration data that is linked to the date of residence, the type of special deduction for housing loans, and the specific acquisition category. Furthermore, the deduction declaration acquisition unit 102a may acquire deduction declaration data when the date of residence, the type of special deduction for housing loans, and the specific acquisition category are set on the declaration screen.

The deduction determination unit 102b determines whether the application for the special deduction for housing loans, etc., conforms to the deduction application period. Here, the deduction determination unit 102b may determine whether the application for the special deduction for housing loans, etc. conforms to the deduction application period based on the housing deduction table master 106c and the deduction declaration data. Furthermore, the deduction determination unit 102b may determine whether the application for the special deduction for housing loans, etc. conforms to the deduction application period by comparing the number of deduction years with the number of years elapsed since the date of first residing in the home based on the housing deduction table master 106c and the deduction declaration data. Furthermore, the deduction determination unit 102b may identify a record in the housing deduction table master 106c that is linked to the type of special deduction for housing loans, etc., and the specific acquisition category set in the deduction declaration data, and determine whether the application for the special deduction for housing loans, etc. conforms to the deduction application period by comparing the number of deduction years set in the record that is linked to the start date and end date of the residence period that constitute the period including the date of first residing in the home with the number of years elapsed since the date of first residing in the home. Furthermore, the deduction determination unit 102b may obtain the number of years elapsed by adding 1 to the number of years obtained by subtracting the year of residence start, including the date of residence start, from the year of declaration for the special deduction for housing loans, etc., based on the housing deduction table master 106c and the deduction declaration data, and may determine whether the application for the special deduction for housing loans, etc., conforms to the deduction application period by comparing the number of deduction years with the number of years elapsed since the date of residence start.

The warning execution unit 102c executes warning processing for an application for special deductions for housing loans, etc. Here, the warning execution unit 102c may execute warning processing if the deduction determination unit 102b determines that the application for special deductions for housing loans, etc. does not conform to the deduction application period. Furthermore, the warning execution unit 102c may execute warning processing by displaying an error message if the deduction determination unit 102b determines that the application for special deductions for housing loans, etc. does not conform to the deduction application period. Furthermore, the warning execution unit 102c may execute warning processing by displaying an error message indicating that the deduction period has expired if the deduction determination unit 102b determines that the application for special deductions for housing loans, etc. does not conform to the deduction application period because the number of years elapsed exceeds the number of deduction years. Furthermore, the warning execution unit 102c may execute warning processing by displaying an error message indicating that year-end tax adjustments are not possible if the number of years elapsed since the date of residence start date is zero. Furthermore, if the deduction determination unit 102b determines that the application for the special deduction for housing loans, etc. does not conform to the deduction application period, the warning execution unit 102c may execute a warning process by displaying an error message on the declaration screen.

The registration unit 102d registers deduction declaration data for special deductions such as housing loans. Here, the registration unit 102d may register the deduction declaration data for special deductions such as housing loans in the tax database 106d.

3. Specific Examples
A specific example of this embodiment will be described with reference to FIGS.

[Housing loan deduction management processing]
An example of the housing loan deduction management process in this embodiment will now be described with reference to Fig. 9. Fig. 9 is a flowchart showing an example of the process of the housing loan deduction management device 100 in this embodiment.

As shown in FIG. 9, the deduction declaration acquisition unit 102a displays the declaration screen on the output device 114, and if the user sets the date of residence start, type of special deduction for housing loans, etc., and specific acquisition category on the declaration screen via the input device 112, acquires deduction declaration data linked to the date of residence start, type of special deduction for housing loans, etc., and specific acquisition category (step SA-1).

The deduction determination unit 102b then identifies the record in the housing deduction table master 106c that is linked to the type of special deduction for housing loans, etc. and the specific acquisition category set in the deduction declaration data, and determines whether the application for the special deduction for housing loans, etc. conforms to the deduction application period by comparing the number of deduction years set in the record that is linked to the start date and end date of the residence period that constitute the period including the start date of residence in the home with the number of years that have elapsed since the start date of residence in the home (step SA-2).

Then, if the deduction determination unit 102b determines that the application for the special deduction for housing loans, etc. falls within the deduction application period (step SA-2: Yes), it transitions the processing to step SA-3.

Then, the registration unit 102d registers the deduction declaration data for the special deduction for housing loans, etc. in the tax database 106d (step SA-3), and the process ends.

On the other hand, if the deduction determination unit 102b determines that the application for the special deduction for housing loans, etc. does not fall within the deduction application period (step SA-2: No), it transitions the processing to step SA-4.

The warning execution unit 102c then executes the warning process by displaying an error message on the declaration screen displayed on the output device 114 (step SA-4), and ends the process.

In this way, in this embodiment, data on the deduction period, which varies depending on the type of deduction and the date the residence began, is managed in a master. When a filer files a housing deduction declaration, the master is referenced to check whether the deduction period is in effect, and if it is outside the period, an error is generated.

Here, an example of the housing loan deduction management process in this embodiment will be described with reference to Figures 10 to 14. Figures 10 to 13 are diagrams showing an example of the housing loan deduction management process in this embodiment. Figure 14 is a diagram showing an example of a declaration screen in this embodiment.

As shown in Figure 10, in this embodiment, when a filer files a return on the return screen in the first year of filing a return for the special deduction for housing loans, etc., if multiple housing loan deductions are applied, deduction return data for the number of applicable items (item A and item B) is entered, and the housing loan balance certificate table and housing loan details table are updated. Here, in this embodiment, the number of times set in the housing loan balance certificate table indicates the number of housing loan deduction details, and the ID set in the housing loan balance certificate table is an identifier that sequentially manages balance certificates linked to housing loan deduction details.

As shown in Figure 11, in this embodiment, when a filer files a declaration on the declaration screen from the second year onwards for the special housing loan deduction, the contents of the previous year's deduction declaration data (online declaration form) are copied, the amount of the balance certificate (entered every year) is displayed blank, and the contents of the first year's housing loan details are copied and displayed. As shown in Figure 11, in the housing loan balance certificate table in this embodiment, the previous year's data is copied when the declaration screen is launched from the second year onwards for the online declaration, and the year-end loan balance is registered as blank data because it changes every year. Also, as shown in Figure 11, in the housing loan details table in this embodiment, the previous year's data is copied and registered as is because it does not change from the previous year.

Furthermore, as shown in FIG. 12, in this embodiment, if a filer files a return on the return screen in 2030 (within the deduction period) for the special deduction for housing loans, etc., 10 years are specified as the number of deduction years based on the housing deduction table master 106c (i.e., Housing Deduction Table Master 106c. Start of Residence Period ≦ Return Screen. Residence Start Date ≦ Housing Deduction Table Master 106c. Residence Period End, and Return Screen. Deduction Type = Housing Deduction Table Master 106c. Deduction Type, and Return Screen. Specific Acquisition Category = Housing Deduction Table Master 106c. Specific Acquisition Category is specified as the number of deduction years). Then, as shown in FIG. 12, in this embodiment, the number of years of residence is calculated from the residence start date and return year (i.e., "Number of Years of Residence" = "Return Year - Residence Start Year + 1" = 2030 - 2021 + 1 = 10 years), and the 2030 return is not determined to be an error by comparing the number of years of residence and the number of deduction years.

Furthermore, as shown in FIG. 13, in this embodiment, if a filer files a return on the return screen in 2031 (a year after the deduction period) for the special deduction for housing loans, etc., 10 years will be specified as the number of deduction years based on the housing deduction table master 106c (i.e., Housing Deduction Table Master 106c.Start of Residence Period≦Return Screen.Residence Start Date≦ Housing Deduction Table Master 106c.End of Residence Period, and Return Screen.Deduction Type = Housing Deduction Table Master 106c.Deduction Type, and Return Screen.Specific Acquisition Category = Housing Deduction Table Master 106c.The number of deduction years that meets the specific acquisition category is specified). Then, as shown in FIG. 13, in this embodiment, the number of years of residence is calculated from the start date of residence and the return year (i.e., "Number of Years of Residence" = "Return Year - Start Year of Residence + 1" = 2031 - 2021 + 1 = 11 years), and the 2031 return is determined to be an error by comparing the number of years of residence with the number of deduction years. Then, as shown in Figure 14, in this embodiment, an error message is displayed on the tax return screen indicating that the deduction period has passed.

Furthermore, an example of the housing loan deduction management process for multiple housing loans in this embodiment will be described with reference to Figures 15 and 16. Figures 15 and 16 are diagrams showing an example of the housing loan deduction management process in this embodiment.

In this embodiment, as shown in FIG. 15, when multiple itemized housing loan deductions are applied, as shown in FIG. 16, for the filing year for the special deduction for housing loans, etc. = 2024, the number of deduction years set in the housing deduction table master 106c is obtained for each item, and checked when entering data on the filing screen. That is, as shown in FIG. 16, in this embodiment, for item A, the number of deduction years: 10 years is specified from the housing deduction table master 106c (i.e., Housing deduction table master 106c.Start of residence period ≦ filing screen.Start of residence date ≦ Housing deduction table master 106c.End of residence period, and filing screen.Deduction type = Housing deduction table master 106c.Deduction type, and filing screen.Specific acquisition category = Housing deduction table master 106c.Specific acquisition category is specified). 16, in this embodiment, for Detail A, the number of years of residence is calculated from the residence start date and the declaration year (i.e., "years of residence" = "declaration year - residence start year + 1" = 2024 - 2014 + 1 = 11 years), and by comparing the number of years of residence with the number of deduction years, the 2024 declaration is determined to be an error. Also, as shown in FIG. 16, in this embodiment, for Detail B, the number of deduction years: 13 years is specified from the housing deduction table master 106c (i.e., the housing deduction table master 106c. residence date period start ≦ declaration screen. residence start date ≦ housing deduction table master 106c. residence date period end, and declaration screen. deduction type = housing deduction table master 106c. deduction type, and declaration screen. specific acquisition category = housing deduction table master 106c. specific acquisition category is specified). As shown in Figure 16, in this embodiment, for Detail B, the number of years of residence is calculated from the residence start date and the filing year (i.e., "years of residence" = "filing year - residence start year + 1" = 2024 - 2021 + 1 = 4 years), and the 2024 filing is not determined to be an error when the number of years of residence is compared with the number of years of deduction.

In this embodiment, when new details are added, the housing deduction table master 106c is referenced, just as in the case of years in which the deduction period has passed, and if master data cannot be obtained from the input content, a similar check may be performed.

In addition, this computer program may be stored on an application program server connected to the housing loan deduction management device 100 via any network, and all or part of it may be downloaded as needed.

In addition, the program for executing the processing described in this embodiment may be stored on a non-temporary computer-readable recording medium, or may be configured as a program product. Here, this "recording medium" includes memory cards, USB (Universal Serial Bus) memories, SD (Secure Digital) cards, flexible disks, magneto-optical disks, ROMs, EPROMs (Erasable Programmable Read Only Memory), EEPROMs (registered trademark) (Electrically Erasable and Programmable Read Only Memory), CD-ROMs (Compact Disk Read Only Memory), MOs (Magneto-Optical disks), DVDs (Digital Versatile Disks), and more. This includes any "portable physical media" such as a Blu-ray Disc (registered trademark) and a Blu-ray (registered trademark) Disc.

A "program" is a data processing method written in any language or description method, and may be in any format, such as source code or binary code. It should be noted that a "program" is not necessarily limited to a single structure, but also includes a distributed structure consisting of multiple modules or libraries, or a structure that achieves its function by working in conjunction with a separate program, such as an OS. The specific structure and reading procedure for reading a recording medium in each device shown in this embodiment, as well as the installation procedure after reading, can use well-known structures and procedures.

The various databases stored in the memory unit 106 are storage devices such as memory devices such as RAM and ROM, fixed disk devices such as hard disks, flexible disks, and optical disks, and store various programs, tables, databases, and web page files used for various processes and website provision.

The housing loan deduction management device 100 may be configured as an information processing device such as a known personal computer or workstation, or may be configured as such an information processing device to which any peripheral device is connected. The housing loan deduction management device 100 may also be realized by installing software (including programs or data, etc.) that causes the device to perform the processing described in this embodiment.

Furthermore, the specific form of distribution and integration of the devices is not limited to that shown in the figures, and all or part of them can be functionally or physically distributed and integrated in any unit depending on various additions or functional loads. In other words, the above-mentioned embodiments may be implemented in any combination, or embodiments may be implemented selectively.

This invention is useful in all industries with companies with a large number of employees eligible for the home loan deduction.
