How Filing Extensions Work
A tax extension is an official request that gives you more time to submit your return, not more time to pay any taxes owed. The cost to file a tax extension is usually zero when you use free electronic options, though paid software or professional services may add fees.
Understanding the timeline is important, because the extension pushes back your filing date, not your payment date. If you expect to owe money, you should still estimate and submit a payment to avoid penalties and interest.
Estimated Costs for Different Filers
For many individual taxpayers, the cost to file a tax extension is effectively zero if you e-file through the IRS Free File program or use free filing software. Self-employed taxpayers and business filers may choose paid tax preparation services, which can increase the total price depending on complexity.
Extension Methods and Fees
Electronic Filing
E-filing your extension through the IRS website or authorized partners is the fastest and often free method, especially for straightforward returns.
Professional Tax Assistance
If you hire a tax professional to prepare and submit your extension, you will pay their service fee, which varies by provider and location.
Tax Preparation Software
Commercial software can guide you through the process, with prices ranging from free for basic versions to higher tiers for more complex situations.
Paper Filing
Filing Form 4868 or Form 7004 by mail is possible, typically at little to no cost, but it takes longer and increases the risk of processing delays.

FAQ
Reader questions
Will filing an extension cost me money if I e-file?
No, most taxpayers can e-file their extension for free through IRS Free File or other approved electronic options, keeping the cost to file a tax extension at zero for basic returns.
Does an extension give me more time to pay my taxes? No, an extension only extends the time to file your return; any taxes owed are still due by the original deadline, and delaying payment can result in penalties and interest. If I hire a tax professional, how much should I expect to pay?
Fees vary widely, but you might pay anywhere from a modest flat fee to a higher hourly rate depending on the complexity of your return and the professional you choose.
What happens if I miss the extended filing deadline?
Missing the new deadline can lead to late filing penalties, late payment penalties, and interest on any unpaid balance, so it is important to submit by the extended due date.
