Income tax prepayment application, corporate taxpayer (5017e)

Corporate taxpayers use this form to request prepayment, recalculation of prepayment, and additional prepayment. Corporations must apply for these prepayments electronically.

Request prepayment online

File your application in MyTax

You can can file the application electronically in Ilmoitin.fi by submitting the file produced by your accounting software or via Apitamo/ApitamoPKI-interface.

When can I use a paper form?

You can file on paper only if there is a special reason (for example, if electronic filing is impossible due to technical difficulties).

If you file on paper, you need not apply for a special permission, and the Tax Administration does not need to be notified of the reason in advance. The processing of a paper application takes more time than the processing of an electronic application.

Fill in the form carefully and follow the instructions. Tax returns filed on paper are scanned and their contents read using OCR technology. For example, when entering the accounting period, use the format ddmmyyyy–ddmmyyyy. Similarly, be sure to enter the Business ID correctly for correct identification of your business. More information is available in the instructions at the bottom of this page.
