Questions about this tool
When is the 2026 individual tax return due in 2027?
Form 1040 for tax year 2026 is due April 15, 2027. An extension moves the return to October 15, 2027, but it does not move the date the tax is due.
What happens when a deadline falls on a weekend?
The deadline moves to the next business day. January 31, 2027 is a Sunday, so the 2026 Forms W-2 and 1099-NEC are due February 1, 2027. May 15, 2027 is a Saturday, so the 2026 Form 990 is due May 17, 2027.
Does an extension extend the time to pay?
No. An extension gives more time to file, not more time to pay. The tax is still due on the original date, and interest and penalties can start from that date.
Are state deadlines the same as the federal deadlines?
Not always. Many states follow the federal date, but some have different dates, automatic extensions or separate estimated payment schedules. Check the state tax agency for each client.
