IMPORTANT: tax extensions only grant you time to submit your tax forms. Any taxes owed, if unpaid on or before April 15, 2026, should be paid as soon as possible, to avoid penalties and interests. For this reason, do not wait until the last minute to work on your taxes!

Lastly, do not forget to pay your 2026 estimated taxes by the various due dates!
