Alternative way to keep track of updates to data specifications

The Tax Administration has released a database resource containing all the data elements necessary for the upkeep of income tax returns.

To include the database feature in the software that you develop is optional. However, it can make your update and maintenance work easier. In other words, software developers can independently choose to use the database it or leave it out.

In Finnish and Swedish:

Specifications MS Access 2021
Tietuekuvaukset MS Access 2021 (zip) (5.10.2021)
(After you download the database and save it in your hard disk, you can open it there.)
Specification in Excel, 2021
Tietuekuvaukset excel-taulukko 2021 (xlsx) (5.10.2021)

Specifications MS Access 2020
Tietuekuvaukset MS Access 2020 (zip) (30.9.2020)
(After you download the database and save it in your hard disk, you can open it there.)
Specification in Excel, 2020
Tietuekuvaukset excel-taulukko 2020 (xlsx) (30.9.2020)

All the data elements of the year's income tax returns are included in both downloads. To work with the database, you need MS Access 2000 or a later version. The Excel file is in the MS Excel format.
