The last day to file individual federal income taxes for the tax year 2024 (filed in 2025) was April 15, 2025. This is the deadline for filing without an extension. If April 15 falls on a weekend or holiday, the deadline may be moved to the next business day. Extensions can be requested to file later, typically until October 15, 2025, but any taxes owed were still due by April 15, 2025, to avoid penalties and interest. Special extensions may apply in some cases, like natural disasters or specific counties, with deadlines extending up to October 15, 2025, or November 3, 2025, depending on location.
For American expats, the deadline to file their 2025 tax return is April 15, 2026, with an automatic extension available until June 15, 2026, and a further extension to October 15, 2026, if properly filed.
