September 2026 Question and Answer

QUESTION:

When is the filing deadline if I requested an extension?

ANSWER:

The deadline is October 15, 2026. Even though you filed for an extension, it’s important that you follow these key rules.

  • No Extra Time to Pay: An extension to file is not an extension to pay. Any taxes owed are still due by the original April deadline to avoid penalties.
  • Estimate Your Tax: You must estimate your total tax liability and pay what you can when submitting the extension to minimize potential failure-to-pay penalties and interest.
  • State Taxes: Check with your state’s tax department, as some automatically accept a federal extension while others require a separate state extension form.
