2026 Tax Filing Guide: How to File Your 2025 Tax Return (Deadlines, Tips & Deductions)

State vs. Federal Tax Filing

Remember to file both federal and state returns. Rules, rates, and deadlines vary by state. Most tax software allows you to file both simultaneously, streamlining the process for the 2026 season.

Common Tax Filing Mistakes to Avoid

• Incorrect Social Security numbers.


• Unreported income (gig work, crypto).


• Choosing the wrong filing status.


• Missing signatures.


• Missing the deadline without an extension.

What to Expect After You File

E-filed returns are typically processed within 21 days. Use the IRS tool to track your refund. Keep copies of your return and supporting documents for at least three years.

Penalties for Late Filing and Payment

Failing to file by April 15, 2026, incurs a 5% monthly penalty on unpaid taxes. Failure to pay has a 0.5% monthly penalty plus interest. File on time even if you can't pay in full, and contact the IRS to set up a payment plan.
