The federal income tax return filing deadline for most individuals is April 15, 2025, for the 2024 tax year. If this date falls on a weekend or holiday, the deadline is moved to the next business day. Taxpayers can request a six- month extension by filing Form 4868, which extends the filing deadline to October 15, 2025, without penalties (unless taxes are owed).
Therefore, the tax return period effectively ends on April 15, 2025, unless an extension is filed, in which case it ends on October 15, 2025. If no extension is filed and the deadline is missed, penalties and interest may apply.
