Need more time to file your 2021 tax return?
If you can’t complete your 2021 federal tax return by the April 15, 2021 deadline, you can buy yourself more time.
Just file an extension to push the deadline back six months to October 15, 2021 and avoid IRS late-filing penalties.
There’s a catch, though. The extension only pushes back the due date for the paperwork. If you owe money, you need to estimate the amount, then file your extension and make your payment by April 17, 2018.
