You didn't intend for it to happen. But suddenly it's mid-April and you've missed the tax-filing deadline. Here's what may happen next if you file your taxes late. (PS: State and local deadlines may vary, so check with the relevant agencies to determine the impact of filing late.)
What happens if you file taxes late?
The ramifications of missing the federal income tax deadline depend on whether you owe the IRS money, it owes you, or you can call it even.
If you owe taxes
If you haven't settled your tab with Uncle Sam by Tax Day, your bill will likely keep growing as penalties and interest pile on.
First, you may face a failure-to-file penalty. This is equal to 5% of the taxes you haven't paid less any available credits, charged monthly for up to 5 months. If you're more than 60 days late, the minimum penalty is the smaller of 100% of the taxes you owe or $485.
You could also get hit with a failure-to-pay penalty. This one is assessed at the smaller rate of 0.5% of your unpaid taxes, but it's reapplied each month until you max out at 25% of your unpaid balance. If you owe both penalties in a given month, the failure-to-file penalty is reduced so that you are not paying more than 5% in penalties each month.
In addition to the penalties above, you likely will also be charged daily interest on what you owe in taxes. This rate is updated quarterly but is generally the federal short-term rate plus 3%. Unpaid penalties may be charged interest in addition to interest that the balance of taxes owed accrues.
If you give the IRS the cold shoulder on your unpaid taxes, it may raise penalty rates over time and file a tax lien—a legal claim to your assets.
If you don't owe taxes
If you don't owe taxes, you won't face any penalties for not filing your tax return. But you may still want to file a tax return for two reasons:
- You could be owed a refund. Filing your tax return gives you the opportunity to claim credits and deductions you're eligible for, and to make sure that if you did overpay taxes throughout the year, you get your money back from the government. You may still be able to claim a refund if you file late—but you typically have to do so within 3 years of when your tax return was originally due.
- The IRS may not have accurate income data for you. In the short term, this may impact the kinds of financial aid you receive from colleges or loans you're eligible for, among other financial services. Longer term, it may lead to lower Social Security payments, specifically for the self-employed.
What can you do if you have to file your taxes late?
If you foresee you won't be able to get your federal tax return in by Tax Day (April 15, 2025), you can ask the IRS for extra time to file. This extension typically gives another 6 months—until October 15, 2025, for 2024 income taxes—to file your tax return. It doesn't, however, impact how long you have to pay your taxes. Payment is still due by Tax Day for income earned in 2024. If you have not paid by then you may start running up the failure-to-pay penalties and interest described above until you've paid in full.
If you can't afford to pay everything you owe by the deadline, you might consider a payment plan, which may decrease the penalties you face. Both short-term and long-term plans are available and can be requested by completing the Online Payment Agreement ApplicationOpens in a new window, through the mail by filling out Form 9465 (Installment Agreement RequestOpens in a new window), or by calling the phone number on your balance notice.
Those who can't pay what they owe in taxes may be able to settle for less if they request an Offer in Compromise (OIC). Check your eligibility with the IRS's OIC Pre-Qualifier toolOpens in a new window, then complete the application package as instructed in the Form 656 BookletOpens in a new window. If you can't afford to pay any of your tax debt, check if you can delay collection by calling the phone number on your collection notice.
