The tax filing deadline of April 15th 2025 has passed. Those who have filed an extension must file by October 15th, 2025. But all tax due must be paid by 4/15 or the IRS will levy a penalty. Contact us for more information.

It’s important to know when taxes are due in 2025. For many, there are more tax deadlines to know about than just the due dates for your federal income tax return. The IRS can levy penalties and interest if you miss a tax deadline. 

  • The standard penalty for failing to file your annual tax return on time is 5% of the tax due for each month (or partial month) your return is late. 
  • If you don’t pay your taxes on time, the monthly penalty is 0.5% of the unpaid amount, up to 25% of what you owe. 
  • You will also owe interest on the unpaid taxes. Penalties apply to missing other tax deadlines, as well. 

Here are the most important 2025 federal income tax due dates for individual taxpayers. 

For most people, April 15 was the last day to file a 2024 tax return, unless you file an application for an  extension with the IRS, which is also due on April 15. If you’re a household worker, you also have until April 15 to file Schedule H and pay employment taxes.

  • April 15 is the last day that you can contribute to an IRA or health savings account (HSA) for 2024. 
  • In addition, except for those who request an extension to file their 2024 tax return, April 15 is the deadline for self-employed people to contribute to a solo 401(k) or a simplified employee pension (SEP) plan for 2024. 
  • If you made excess IRA contributions in 2024, these must also be withdrawn by April 15.
