The processing plant where you sell the fish reports and pays the taxes to the Tax Agency on your behalf.
If you sell fish to hotels or grocery stores, you do not use your fish trading tax card. However, you still have to pay taxes on your income! Here’s how it works: The hotel or store buying your fish is required to report the purchase. They provide this information to the Employer Register (Sulinal) when submitting the annual salary statement (A11 form), which must be filed by January 31 of the year following the income year.
This ensures that your income is properly reported, and the taxes are paid accordingly.
