Filing a tax extension gives you extra time to submit your return — but it does not extend the deadline to pay any taxes owed. If you expect to owe taxes, the IRS still requires payment by the original filing deadline.

Submitting an estimated payment with your extension can help reduce penalties and interest. Even a partial payment can make a difference. If you’re unsure how much to pay, a tax professional can help you estimate your liability and choose the best approach to stay compliant while minimizing extra costs.
