Automatic Extension to File (Individuals)

If you cannot file your personal income tax return by the April 15 deadline, you have an additional 6 months, to October 15, to file your return without having a late filing penalty imposed. However, the extension to file your tax return is not an extension to pay your tax. You must pay your tax in full no later than the April 15 deadline, regardless of when you file your return, or a late payment penalty may be imposed. If April 15 falls on a weekend or holiday, the tax return may be filed, and the tax payment may be remitted on the next business day following April 15, without imposition of a penalty for late filing of a return or late payment of tax.

Avoid penalties and interest

To avoid late payment penalties and interest, you must pay your taxes by April 15 for the current tax year even if you cannot file by this date.
