Check and report the information on your investments to the Tax Administration, if necessary.

Some of the information on your investments may be shown in the pre-completed tax return automatically. In that case, it is enough if you check the information.

Review and, if necessary, report additional information on all profits and losses from your investments, both in Finland and abroad. Make sure that the Tax Administration has the correct information on:

  • your capital gains or losses from sold corporate stock and fund shares
  • your dividend income
  • the profits from your investment fund shares
  • the profits in your equity savings account, if you withdrew money from it
  • income in the form of revenues from life insurance contracts, either investment-based or savings-based (including a “shell” contract)
  • the profits from a capital redemption policy.

If you have sold shares or other securities through a foreign remote intermediary, also report the profit or loss from these transactions. The Tax Administration receives information about securities trading abroad and monitors that the details of these transactions are submitted to the Tax Administration.

Check your pre-completed tax return

Check that the information in the pre-completed tax return you received in the spring is correct. Report missing information and correct inaccurate information related to your investments either in MyTax or with a paper form. Provide information on the day indicated on your tax return at the latest.

Report the information on your investments in MyTax

How to file the selling of securities in tax return

If you provide information on your investments on a paper form, always use the correct form:

  • Use form 9A (Capital gains and capital losses from trading with securities) for reporting all gains and losses due to the sale of securities in Finland and abroad. Also use this form to report any sales carried out through a remote intermediary in a foreign country (for your other capital income received through a foreign remote intermediary, complete Form 16B).
  • Use form 50B (Capital income and deductions) for reporting dividends and profit shares of investment funds
  • Use form 16B (Statement on foreign income (capital income)) for reporting any dividends and profit shares of investment funds you have received from abroad, as well as any taxes you have paid abroad.

Do not forget to deliver the paper forms to the Tax Administration on time. Please note that they must arrive on the date indicated on your tax return at the latest.

How to declare with paper forms

Tax-exempt sales profits must also be reported to the Tax Administration

Check the pre-completed tax return to ensure that sales of shares under EUR 1,000 are also included in the tax return. Complete the information, if necessary.  Sales profits are tax-exempt if the total price of shares you have sold during a calendar year was EUR 1,000 at maximum.

Read more about tax-exempt sales profits in section 3.2 ‘Pienet luovutukset’ of the detailed tax instructions ‘Arvopaperien luovutusten verotus‘ (in Finnish).

Save the documents

Remember that you must keep the information needed to calculate the sales profits and losses from your securities for 6 years, starting from the beginning of the year after the end of the tax year.

If you use a securities account, i.e. an electronic stock portfolio, in your investments, it is enough to keep the related account statements. If you have investment fund shares, keep the reports you receive from the fund management company.

Store the documents either on paper or in electronic format. It must be possible to print out the electronic documents on paper if necessary.

Read more about the obligation to keep records in section 5 ‘Muistiinpanot’ of the detailed tax instructions ‘Verovelvollisen ilmoittamisvelvollisuus’ (in Finnish).

Frequently asked questions

Note that CFDs are not crypto assets and their tax treatment is different from that of profits from crypto assets. The rules on capital gains tax are not applied to CFDs, and losses cannot be deducted from profits.

If you make a profit on a CFD, it will be taxed as capital income. The tax rate for capital income of up to €30,000 is 30%, and the tax rate for any income exceeding that is 34%.

Losses from CFDs are not taken into account in tax assessment in any way, not as capital losses nor as tax-deductible expenses.

Please note that in the taxation of CFDs, every transaction will be processed independently. This means that any profits made from trading CFDs will be taxed as capital income and that losses from trading CFDs cannot be deducted from profits. If you are trading CFDs, you can therefore lose the capital you have invested and still be liable to pay tax on the profits you make.

File your income on the pre-completed tax return

Add up the profits you have made on CFDs and report the amount on your pre-completed tax return in MyTax under Foreign income – Other foreign capital income. If you file on paper, use Form 16B Statement on foreign income (capital income).

Note that losses from or expenses for CFDs need not be filed on the tax return because they cannot be deducted from the profits.

The Tax Administration receives information on foreign-sourced income and supervises their tax filing.
