How to pay VAT and other self-assessed taxes

You can pay VAT and other self-assessed taxes in MyTax. See our How to pay taxes in MyTax guidance.

The following information is pre-completed in the payment template of MyTax:

  • Reference number
  • Bank account number
  • Payment amount (the current day's balance including interest, but if you need to change the amount you can do so)
  • Payment date (always the current date)

If you pay the tax directly in your online bank, or if you pay via your accounting software or by some other method, you should first check the payment details carefully before sending off the payment. To check the details,

  • log in to MyTax, or
  • read the summary that you receive once a month.

The Tax Administration does not send you separate bank forms for the payment of self-assessed taxes.

When must the taxes be paid?

You must pay your taxes by their due date. The general due date for self-assessed taxes is the 12th of each month. If the 12th falls on a Saturday, Sunday or a public holiday, the due date is extended to the next business day.

Actual due dates vary for taxpayers of self-assessed taxes depending on their tax period. Check the due dates for different tax periods on this page.

Which reference number to use?

Use the reference number for self-assessed taxes when paying self-assessed taxes. Your payment is allocated to the correct taxes and the correct taxpayer based on the reference number. You can check the reference numbers in MyTax.

How to find the correct reference number in MyTax

The old tax-account reference number will stay in use for the time being, and payments made with this reference number will be allocated correctly. The e-service still uses the tax-account reference number.

When paying, use the international RF-format reference number. This means that you must enter the full RF code, including the letters 'RF'. If you cannot enter the entire code, you can leave out the first four characters.

Different types of taxes have their own reference numbers. The Tax Administration uses your payment to cover different taxes in different situations according to the reference number. Read more about using payments for different taxes.

When will the payment show in MyTax?

If you paid the self-assessed tax via Nordea, OP or Danske Bank, the payment should be visible in MyTax on the next business day after the payment date. VAT payments made through other banks usually show after two business days.

In some situations, the delay may be longer. If you have made the payment but it does not show in MyTax, please check again on the following day. The payment date recorded by your bank will be considered the payment date even if there is a delay in transferring the payment to MyTax.

What if I pay late?

If you pay a self-assessed tax after its due date, you must pay late-payment interest in addition to the tax itself. For 2020, the rate is 7%. The rate is reviewed every year. Unpaid taxes accrue interest, starting on the due date and continuing until the day they are paid.

On the last date of each month, the system creates a summary on the transactions of self-assessed taxes. If some of your self-assessed taxes remain unpaid on that date, the summary will contain a reminder text. The summary also always gives you instructions for payment. Read more about summary on tax payment status.

Log in to MyTax to check the exact amount and late-payment interest, valid on the date when you plan to make the payment. If you just look at the summary, you see only the late-payment charges that were valid on the date when the system created the summary.

Can taxes be paid in advance?

You can make payments in advance with the reference number for self-assessed taxes. However, the payments will not be used to cover the self-assessed tax until the tax is due for payment. Please note that if you have some overdue taxes, all available payments will be used to cover them because they are due at the end of the month, including any taxes covered by a payment arrangement and any third-party taxes for which you are accountable. If any of your self-assessed taxes have been transferred to the enforcement agency for collection and a new tax has not yet fallen due, the system will use your payment towards the taxes in enforced collection. In this case, you should delay your payments of new self-assessed taxes, i.e. not pay them until their due date.

Normally, if you pay self-assessed taxes before their due date, the paid-in balance will earn credit interest. The interest period begins on the date of payment and continues up to the due date of the taxes.

Credit interest is reviewed annually and it is based on the reference rate in accordance with the Interest Act. In 2020, the interest rate is 0.5%.
