Requesting an extension isn't the same as paying later: IRS warns about penalties and how to avoid them

Every year, millions of Americans face IRS deadlines with doubts and delays. The possibility of requesting more time to file often seems like an attractive solution. However, many are unaware that this doesn't mean a delay in paying taxes.

The IRS has wanted to clear up this confusion and has sent a direct message to taxpayers. The consequences of not paying on time can be serious, even if an extension to file the return has been granted. That's why understanding how this extension works is key to avoiding penalties.

Requesting an extension doesn't stop the IRS clock

The IRS allows taxpayers to request an automatic extension until October 15. This extension refers only to additional time to file the return; under no circumstances does it extend the deadline to pay owed taxes. If payment isn't made before the original deadline, penalties begin to apply.

The IRS also accrues interest on any outstanding amount from the first day of delay. That's why the main recommendation is to pay before the due date, even if some documentation is still missing.

The extension can be easily requested through several methods, one of the most popular being the IRS Free File program. Taxpayers can also submit Form 4868 or make an electronic payment by selecting the extension option.

More than 19 million taxpayers have already requested extra time

According to IRS data, around 19 million extension requests were recorded in the 2025 tax season. This confirms that it's a widespread practice, especially among those who need to gather more paperwork. Even so, many of them make the mistake of also postponing payment.

The tax agency insists that taxpayers should calculate the approximate amount of their taxes. Even if all the information isn't available, it's better to pay something before the deadline. This can prevent a considerable penalty and keep the tax record trouble-free.

The IRS offers online tools that help estimate and make payments easily. Using these resources reduces the margin of error and avoids future complications. In addition, it helps keep a smooth relationship with the tax administration.

Tips to avoid problems with the IRS

The main recommendation is not to wait until the last minute to act. Those who already know they won't be able to file on time should request the extension as soon as possible. Above all, they should accompany it with an estimated payment.

The IRS reminds taxpayers that a simple partial payment can make the difference. By sending it along with the extension request, it's considered that the payment requirement has been met. This action helps minimize or even completely avoid penalties.

In summary, the IRS's message is clear: requesting more time to file doesn't mean paying later. Understanding this difference is essential to avoid additional charges, interest, and future tax headaches.
