If your income seems to be higher or lower than expected, you need to fill in a preliminary income tax return and send it to the Swedish Tax Agency.
It is important that you pay neither too much nor too little preliminary tax. You can submit as many preliminary tax returns as you need.
Correcting your preliminary tax using our digital service Preliminär inkomstdeklaration (Preliminary tax return), means several benefits for you compared to using a paper form:
It is always appropriate to submit a preliminary tax return if your income seems to be higher than expected. But if it seems to be around 30 percent higher or more, but not less than one price base amount, you are obligated to do it according to Swedish law.
If an agent helps you with your finances, you can use our digital service Ombud och behörigheter (Agents and access) to give the person access to fill in and leave us your preliminary tax return.
If you use a digital mail box, you will receive your mail from us digitally instead of on paper.
