Automatic Extension to File (Individuals)

If you cannot file your personal income tax return by the April 18 deadline, but will have a refund or no balance due, you automatically get a 6-month extension to file your tax return by October 17 for that tax year. If your return will show a balance due, you may make an extension payment by the April 18 deadline, that will cover your tax liability, to receive the filing extension and avoid late payment penalties and interest.

Important: An extension to file is not an extension to pay. You must pay your taxes by April 18.

Avoid penalties and interest

To avoid late payment penalties and interest, you must pay your taxes by April 18 for the current tax year even if you cannot file by this date.
