2027 tax deadlines

Dates marked Expected come from the IRS's draft 2027 tax calendar (Publication 509) or the weekend-and-holiday rule, and the IRS hasn't finalized them. Check again in January. The IRS can also postpone deadlines after a declared disaster, such as a hurricane.

Texas

Texas has no state personal income tax, so most Texans file only a federal return. If you lived or worked in another state during the year, that state may have its own deadline.
