@kmsthorn as long as you are due a refund, the IRS isn't really going to care that you have not submitted the tax return. As long as you have that extension, you can claim the refund as long as the tax return is filed by Oct 15, 2026 (3 years). if you owe, you owe and there is no deadline by which the money you owes magically disappears or the interest clock stops.
do you owe or do you anticipate a refund?
what is the challenge to getting this complete? there is still another 45 days until Oct 15.
