Filing and paying self-assessed taxes
File VAT, employer's contributions and other self-assessed taxes online in MyTax. Make the payments in MyTax, too.
Filing and paying online
Tax returns on self-assessed taxes including VAT and employer's contributions are to be filed electronically. For example, the Tax Administration's MyTax may be used (tax.fi/mytax). Tax Account Online is no longer in use.
For 2017, taxes must be filed online: you only can file VAT, employer's contributions and other self-assessed taxes on paper if there is a special reason (for example, if electronic filing is impossible due to technical difficulties).
Due date for filing and paying self-assessed taxes is the 12th of the month. If the 12th falls on a Saturday, Sunday or a public holiday, the last day to file is extended to the next business day. Returns filed online and on paper have the same due date. Filing the tax return on the paper form is not allowed but as an exception.
Tax periods for VAT and employer's contributions may be different.
The default tax period is the calendar month. In this case, employer's contributions must be filed and paid by the 12th of the month that comes after the payroll month. VAT must be filed and paid by the 12th of the second month that comes after the tax period. For example, the VAT return for January must arrive by 12 March.
If your tax period is the quarter, you must file and pay both employer's contributions and VAT by the 12th of the second month after the end date of a calendar quarter. For example, the tax return for the first calendar quarter must be filed and the taxes paid by 12 May.
The tax period for VAT can also be the calendar year. In this case, by way of exception, the due date is not the 12th: instead, the last day to file and pay VAT is the last day of February.
The extended periods above (the calendar quarter and year) are for small businesses. They must make a specific request for extended tax periods. Read more about requesting extended tax periods.
Use the calendar to check the filing dates. Important dates for business taxpayers.
If the business is terminated or if the tax period is changed
Check the due dates for the tax return and the payment if the tax period has changed or if the business is to be terminated. Further information:
Use the calendar to check the filing dates
Making corrections to filed tax returns
Corrections must be made by replacing a previously filed return by a replacement return. All the information must be re-submitted for the tax concerned by the correction. It is not enough if you just send a correction of a single error.
Filing a tax return past deadline
If the first return for the tax period is filed late, a day-based charge of three euros per day is imposed for the first 45 days. The maximum amount of this late penalty charge is €135.00.
If you make a correction to that return and this replacement return is filed late by max. 45 days, no late penalty is imposed.
Paying self-assessed taxes
The Tax Administration does not send you a bank form for the payment of self-assessed taxes. You must use the reference number for self-assessed taxes when paying, and make the payment by the due date of your tax period. The reference number is displayed in MyTax. However, the old Tax Account reference number can still be used until further notice.
You can also pay a self-assessed tax before its due date when you use the reference number for self-assessed taxes.
You receive a summary of your transactions once a month. Read more about the summary.
When you make a payment in MyTax, the bank account number, reference number, recipient name and payment date are prepopulated so you don't need to fill them in. The pre-populated amount to pay is the current day's balance including interest, but you can change the amount. Payment date is always the present day.
When paying, use the bank accounts of self-assessed taxes – the bank account numbers are:
|Nordea||FI64 1660 3000 1176 25||NDEAFIHH|
|Danske Bank||FI56 8919 9710 0007 24||DABAFIHH|
|OP||FI35 5000 0120 2535 04||OKOYFIHH|
Payments to the Tax Administration, routed through Nordea, OP and Danske Bank normally show in MyTax on the next business day after the date of payment. Payments through other banks show in MyTax in two business days. The delay may occasionally be longer. If you have paid in money but it is not showing in MyTax, please check it again on the following day. Although the transfer of funds might take longer than usual, our recording system always treats incoming payments as paid on the date when the bank has recorded the amount.
Every time you pay taxes it is very important that you enter the proper reference number. Reference numbers help us reconcile incoming payments with the right taxpayer.
- The self-assessed taxes reference: use this number for payments of self-assessed taxes; they are VAT, employer contributions, and others. When you use MyTax to pay self-assessed taxes, the reference number and other payment details are automatically transferred to the e-bank files. Other ways to find the reference number are to look it up on the summary's payment details, and to log in to MyTax and go to Activities > Pay taxes or request refund.
- The taxpayer-specific reference: use this number for payments of any self-assessed taxes that are late. To find this reference number, look it up on the Summary of MyTax, under the payment details of overdue taxes.
If you have filed some taxes and charges that you believe should show on the summary but are not showing, please make sure your self-assessed tax return contained the right tax period, and make sure you used the right reference number when you made a payment. You can view the information in MyTax already before the summary is created. The reference number for payments to Tax Account: The old Tax Account reference number will work for the time being, and payments are allocated correctly. We recommend you start using the self-assessed reference number as soon as possible because that will ensure that your payments are correctly matched with your tax liabilities. To look it up, visit MyTax. It should be noted that the old Tax Account reference number is still in use in the Palkka.fi e-Service.
Use the international 'RF' reference: you must enter the entire string including the letters 'RF' (as in RFXX XXXX XXXX XXXX XXXX XXXX). It may be that you cannot feed the entire string ‒ if this happens, try leaving out the first four characters (leave out 'RFXX' as shown in the example).
If you pay a self-assessed tax after its due date, you not only must pay the tax but also a late-payment interest. For 2018, the rate of interest is 7%. It is reviewed every year. The unpaid taxes accrue interest from the due date up until the day they are paid.
A summary on the transactions of self-assessed taxes is made on the last date of each month. If you have a negative balance at that date, meaning that you have an unpaid self-assessed tax, the summary will contain a reminder text. It also has a guidance text with instructions for payment.
Check the amount and interest payable in MyTax (tax.fi/mytax). However, you cannot calculate the interest in MyTax unless you have filed a full tax return for self-assessed taxes, or if they are not yet included in your MyTax balance.
Normally, we follow the order of due dates and expiration dates (oldest first) when applying the payments on taxes and other receivables. Act on tax collection contains more exact provisions on the order of priority. If the tax is overdue and has late-payment interest, this is settled first, and the tax (the principal) is settled second.
An amount intended as payment of self-assessed taxes is first applied on the taxes that have fallen due. If money remains in credit, it is left waiting for upcoming self-assessed taxes, following the agreed rules on refund dates and refund limits. It is to be used when taxes fall due. On the last day of a month, and when a refund is being sent to the taxpayer, money in credit may also be used for settling other debts that are not self-assessed taxes. If there is still some money, it is either applied to receivables outside those of the Tax Administration or refunded to the taxpayer.
If you pay self-assessed taxes before their due date, the paid-in balance will earn interest. The interest period begins on the date of payment and continues up to the due date of the taxes. It is only paid on the amount to be used as settlement for taxes.
The rate of interest paid on a credit balance is the reference rate of Bank of Finland, in force during the six months preceding the current calendar year, minus two percentage points. However, it cannot be less than 0.5%. It is reviewed every year. In 2018, the interest rate is 0.5%.
What taxes are self-assessed?
Self-assessed taxes are the types of taxes that the Tax Administration does not invoice from taxpayers separately. Instead, the taxpayer is expected to calculate, file and pay them independently. However, transfer taxes and supplementary prepayments are not self-assessed taxes as referred to in this guidance article. Time limits for filing and paying are defined by law.
