As the tax deadline nears, many taxpayers find that they need more time to gather their documents, sort through their finances, or simply to avoid the stress of filing their taxes at the last minute. While the IRS offers an automatic extension to file your tax return, it’s important to remember that an extension to file is not an extension to pay.
A tax extension gives you an additional six months to file your tax return. For most individuals, this means that they will have until October 15 to file if they submit a timely extension request before the usual April 15 deadline. While this allows you more time to complete your paperwork and ensure accuracy, it does not extend the due date for any taxes owed.
To avoid paying costly penalties and interest, you should know that the IRS expects you to pay what you owe by the original deadline, typically April 15, even if you’ve been granted an extension to file. If you fail to pay your taxes on time, you’ll face significant penalties.
When you file for an extension, the IRS simply gives you extra time to complete your tax return. Taxes are due when earned or accrued, not when your return is filed. For example, if you earned income in 2024, the IRS expects you to pay taxes related to that income by April 15, 2025, regardless of whether you file on that date or extend your filing date.
If you file for an extension and do not pay the required amount by the deadline, you will face penalties and interest on the unpaid balance. The failure-to-pay penalty is typically 0.5% per month of the unpaid balance, and the interest rate charged on late payments is determined by the federal short-term rate, which fluctuates. This means that while your extended filing deadline may give you extra time to complete your return, it does not prevent the IRS from charging you interest and penalties for not paying on time.
To avoid these penalties, you should make sure to estimate and pay as much of your tax liability as possible by the April deadline. Here's how you can ensure that you’re in the clear:
If you don’t have all the necessary documents or can’t complete your return in time, attempt to approximate the amount you owe using the information you already have. You can use forms such the 1040-ES to help estimate your taxes if you’re self-employed or if you have other sources of income that aren’t subject to withholding.
If you can’t pay the full amount, it’s important that you pay as much as you can. The IRS offers several payment options, including installment agreements that allow you to pay off your balance over time. The more you pay up-front, the less you’ll have to pay in penalties and interest.
The IRS provides several online tools to assist taxpayers in paying on time. These include Direct Pay, which enables you to make direct payments from your bank account and Electronic Federal Tax Payment System (EFTPS), which provides additional flexibility for business owners or individuals with complex tax situations.
If you owe a large amount of tax each year, you should consider changing your withholding to prevent underpayment penalties. This approach could help you avoid the need for large estimated payments.
