FAQ

When is the federal tax filing deadline?

For most individual calendar-year filers, the regular federal deadline is generally April 15 unless it falls on a weekend or legal holiday.

Does a tax extension give me more time to pay?

No. An extension generally gives more time to file, not more time to pay. Estimated tax owed is still generally due by the regular deadline.

Can state tax deadlines be different?

Yes. State deadlines, disaster relief, military rules, and local legal holidays can change the date. Always verify with the IRS and your state tax agency.
