Using the additional prepayments calculator, corporate entities can calculate the additional prepayment amount they must request and pay after the end of the tax year. The calculator is intended for all corporate entities.
Calculator for additional prepayments
If the corporate entity has not made enough prepayments during the tax year, you can use the calculator to estimate the additional prepayment and the late-payment interest with relief until a due date of your choice.
Please note that the calculator can only give a rough estimate. The values you have entered in the calculator are not saved or transmitted anywhere.
An additional prepayment must be requested before it can be paid. The request must be submitted before the corporate entity’s tax assessment has been completed. Read more about additional prepayments.
Individual taxpayers (private individuals, self-employed individuals, etc.) can estimate the additional prepayment amount with the tax rate calculator.
