You must take care of paying the taxes on the sales profit of your investments, such as shares and fund shares. When you sell shares, you must pay tax on the sales profit.
With regard to dividend income, profit shares of investment funds and income from equity savings accounts, the payor or the bank withholds taxes and forwards them to the Tax Administration. This means that you do not need to take care of the taxes yourself.
You must pay capital income tax on the profit you receive from selling your investments.

You can either pre-pay the tax on the sales profit or make an additional prepayment.

You can request prepayment by one of the following methods:
How to apply for prepayment online in MyTax
You will receive a decision on income-tax prepayment in MyTax and by post. If you have activated suomi.fi/messages, you will receive an e-mail message to the e-mail address you have given. The message will inform you of the prepayment decision being ready for viewing in MyTax. The decision includes information on how to pay the tax. You can pre-pay either in MyTax or in your e-bank, as an e-invoice or through direct debit.
.
If you have not requested prepayment, or if the prepayment was not large enough, you can apply for an additional prepayment. An additional prepayment can request and pay starting the tax year’s December. After you have submitted the request, you receive the Tax Administration’s decision concerning pre‑assessment enclosed with a bank transfer form. If you submit a request and determine a January due date for your additional prepayment, you do not have to pay late-payment interest with relief.
See the instructions: How to request and make an additional prepayment.
If you request and make a sufficient additional prepayment, you will not need to pay back taxes. You can request an additional prepayment by one of the following methods:
How to request an additional prepayment in MyTax
When you have requested an additional prepayment, you will receive the payment details and the decision on the additional prepayment in MyTax and by post. You can make the additional prepayment in MyTax or your online bank, for example.
You can also request an additional prepayment later, as long as you do it before your tax assessment ends. You can see the end date of your tax assessment on the tax decision you have received.
Please note, however, that you will have to pay late-payment interest with relief on the additional prepayment starting from the end of February until the due date of the back taxes or the due date of the additional prepayment.
You can see the amount of the late-payment interest with relief in MyTax, for example.
Example: Jaana sold EUR 20,000 worth of shares in December 2025. She received EUR 5,000 as profit from selling the shares. Jaana must pay EUR 5,000 × 30% = EUR 1,500 of capital income tax on the sales profit.
Jaana should request an additional prepayment and make the payment it in January 2026. In this way, she can avoid back taxes and late-payment interest with relief.
See instructions: How to request and make an additional prepayment.
The end date of Jaana’s tax assessment is only at the end of June 2026, and therefore she can request and make an additional prepayment until then, if she wants. Starting from February 2026, however, she will have to pay late-payment interest with relief on the additional prepayment.
Before paying you the dividend or profit share of an investment fund, the company withholds tax on the amount. The company also forwards the withholding tax to the Tax Administration. This means that you do not have to pay the tax yourself.
When you receive the pre-completed tax return, check all the information. If information on dividends or profit shares of investment funds is not included in the tax return or if the information is inaccurate, log in to MyTax and make corrections by the due date indicated on the return.
