Frequently Asked Questions
Does filing an extension give me more time to pay?
No. An extension gives you 6 more months to file the paperwork, but taxes owed are still due by April 15. Paying late triggers interest and penalties on the unpaid balance.
What if April 15 falls on a weekend?
The deadline shifts to the next business day. If April 15 is a Saturday, the deadline becomes April 17 (Monday). Emancipation Day in Washington DC can also push the deadline a day.
