A Tax Extension Gives You More Time to File, Not More Time to Pay
One of the most common misconceptions during tax season is that filing an extension delays your payment obligations. Understanding how the IRS treats filing vs. payment can save you from unexpected interest and penalty charges.
Filing Penalty vs. Payment Penalty: The failure-to-file penalty is generally 5% of the unpaid taxes for each month or part of a month that a return is late (up to 25%). By contrast, the failure-to-pay penalty is 0.5% per month. Filing Form 4868 eliminates the harsher failure-to-file penalty as long as you submit your return by the extended deadline.
How to Pay What You Owe: If you estimate you owe taxes, you should submit your payment alongside your extension request or via IRS Direct Pay, EFTPS, or an approved payment processor by the original due date (generally April 15).
Keep Your Documentation: Always retain your submission confirmation and payment receipt for your records.
