Is There a Penalty for Filing a Tax Extension?

Tax season can be challenging, and taxpayers sometimes require additional time to organize their financial information. A common solution is a tax extension, which provides additional time to prepare and submit a tax return. However, an extension does not automatically extend the deadline for paying any taxes owed.

Understanding a Tax Extension

A tax extension provides individuals with additional time to file their tax return with the Internal Revenue Service (IRS). This formal request is typically made using IRS Form 4868, Application for Automatic Extension of Time to File U.S. Individual Income Tax Return. It is generally granted automatically upon request, providing an additional six months to submit the return.

An extension only postpones the deadline for filing your return, giving you more time to gather documents and complete forms. It does not extend the deadline for paying taxes owed. The payment due date remains the original tax deadline, typically April 15, for most individual taxpayers. Taxpayers are still expected to estimate and pay their tax liability by the original due date to avoid penalties.

Penalties for Not Paying on Time

Taxpayers who do not pay their tax liability by the original due date, even with an extension, may face a “failure-to-pay” penalty. This penalty, outlined in 26 U.S. Code § 6651, is 0.5% of the unpaid taxes for each month or part of a month the taxes remain unpaid. It can accumulate up to a maximum of 25% of the unpaid tax.

In addition to the failure-to-pay penalty, interest is charged on underpayments from the original due date until the tax is paid in full. This interest rate is determined quarterly and accrues daily on the unpaid balance, including any penalties. Additionally, taxpayers may incur estimated tax penalties under 26 U.S. Code § 6654 if they fail to pay enough tax throughout the year through withholding or estimated tax payments. These penalties apply if the tax paid is less than 90% of the current year’s tax or 100% (or 110% for higher incomes) of the prior year’s tax.

Penalties for Not Filing on Time

A “failure-to-file” penalty applies when a taxpayer does not submit their tax return by the due date, including any valid extensions. This penalty is specified under 26 U.S. Code § 6651. It is more substantial than the failure-to-pay penalty, typically assessed at 5% of the unpaid taxes for each month or part of a month the return is late.

This penalty also has a maximum accumulation of 25% of the unpaid tax. Critically, filing IRS Form 4868 by the original tax deadline prevents this specific failure-to-file penalty, provided the taxpayer files their return by the extended due date. However, if a taxpayer fails to file by the extended deadline, the failure-to-file penalty will then be applied. It is important to note that if both the failure-to-file and failure-to-pay penalties apply in the same month, the failure-to-file penalty is reduced by the failure-to-pay penalty for that month.

Steps to Avoid Penalties

To effectively avoid tax penalties, taxpayers should accurately estimate their tax liability and ensure any owed taxes are paid by the original tax deadline, even if they file for an extension. This proactive approach ensures compliance with payment obligations. Taxpayers can utilize various approved methods for making payments, such as IRS Direct Pay, the Electronic Federal Tax Payment System (EFTPS), or payment through tax software.

It is equally important to file the tax return by the extended deadline if an extension was requested, or by the original deadline if no extension was filed. Timely submission of the return, coupled with timely payment of taxes, helps prevent penalties. Seeking professional tax advice can also be beneficial, especially for those unsure about their tax obligations or how to accurately estimate income and deductions.
