Calculator for additional prepayments

This calculator helps you estimate how much more advance tax your corporate entity must pay before you submit a request and pay the Tax Administration an additional prepayment (this can be done after the corporate entity’s tax year has ended).

The calculator is intended for all kinds of corporate entities.

Calculator for additional prepayments

Using the calculator

If the corporate entity has paid too little as prepayments during the tax year, feed the relevant values into the calculator to estimate the additional prepayment and interest that will be needed.

Please note that the calculator can only give a rough estimate. Your input into the calculator is not saved or sent on to any database.

Additional prepayments cannot be paid without submitting a request first. The Tax Administration accepts requests for additional prepayments up to the date when the year's tax assessment for the corporate entity is finished. Read more about additional prepayments
