When are taxes due?
April 15 for federal returns, or the next business day when the 15th falls on a weekend or a DC holiday. Most states match the federal date, though a few run their own calendar.
You can file for an automatic six-month extension to October 15, and here is the part people get wrong: the extension covers the paperwork, not the money. If you owe, payment is still due in April, and interest plus penalties run from April 15 on any unpaid balance.
If you cannot pay in full, file anyway. The failure-to-file penalty is roughly ten times the failure-to-pay penalty, and the IRS offers payment plans online in minutes.
Federal taxes are due April 15, or the next business day if that lands on a weekend or holiday. An extension moves the paperwork to October 15, not the payment.
