Remember that all commercial fishers with vessels over 6 meters must report financial information by November 1. Reporting is done via Sullissivik, and you can find a link here.
This registration ensures that you pay resource fees for the fish species subject to such fees. The Tax Agency publishes the rates for these fees.
Tax Return - Deadline May 1 (May 15 if filing digitally)
You must submit a tax return. Along with your tax return, you need to submit your financial statements. If you have depreciations, such as on a boat, you must also submit a depreciation form.
The deadline is May 1, but if you file digitally, the deadline is May 15.
