- If you have paid too much or too little tax in advance, this is corrected in July of the same year as the tax return is filed. If you have paid less than you should have, you are required to pay the difference, and if you have paid more than you should have, you receive a refund.
- Tax returns are submitted online (skattur.is). All taxpayers aged sixteen or older receive a password at their legal residence. If a tax return is not filed, the Directorate of Internal Revenue will estimate your income and calculate the dues accordingly.
You can find information in English on tax payments, taxation and other matters on the website of the Directorate of Internal Revenue
