Send some of your tax-return data in advance

Many details that concern the 2023 tax year can be entered in MyTax beforehand. If you do that, the amounts and information will appear on the pre-completed tax return that you receive at the end of March or beginning of April.

Examples of what you can enter and save now: your deductible 2023 travel expenses, the credit for household expenses, any deductions for a second home in another district because of your work, information on rental income, information on capital gains and losses from the sale of property (other than corporate stock and securities). If you file the information by 21 February 2024, it will be included in your pre-completed tax return.

At the end of March or beginning of April, you can check and – if necessary, make corrections to – the rest of the contents of your tax return such as wage amounts and any capital gains and capital losses from your trading with securities as you receive your pre-completed tax return or when MyTax starts showing the return for you online.

Here is how to proceed:

  1. If the Check your pre-completed tax return link does not appear, your tax return is not yet in MyTax. 
  2. However, you can still enter some of the information in advance for your tax return. If you choose to do that, go to Tax year 2023 first, and then select Filing income and deductions. 
  3. Note: in any case, we recommend that you check the pre-completed tax return carefully when you receive it in March–April in MyTax or by post.
