Social Insurance Administration: Settlement and collection
What if the income from the tax return belongs to other years?
In the case of a recalculation, income according to the tax return of the year in question is used. If the income shown therein belongs to other years, it is possible to request a transfer of income between years and a re-introduction of the tax return at RSK.
It is not certain that the transfer of income between years will result in higher pension rights from the TR and it may even result in lower rights. If you request a re-introduction of tax returns from the RSK, you must send the TR confirmation that this has been done so that the collection of debts can be delayed. It must be kept in mind that the transfer of income between years can result in a change in previously levied public levies and interest and child benefit from the RSK. In addition, it can affect payments of other rights based on information from the tax return.
