The deadline to file individual tax returns for the 2025 tax year is April 15, 2026. Taxpayers can request an automatic extension until October 15, 2026, but any taxes owed must still be paid by the April deadline to avoid penalties and interest.
The deadline for partnerships is March 16, 2026. An extension can be filed to extend the deadline to September 15, 2026.
S Corporations must file by March 16, 2026. Extensions are available until September 15, 2026.
For calendar-year C Corporations, the deadline is April 15, 2026. Extensions are available until October 15, 2026.
If a filing deadline falls on a weekend or federal holiday, the deadline may shift to the next business day. We recommend confirming dates in advance or consulting with a professional tax advisor to ensure compliance.
