What Happens If You Don't File Or Pay Your Taxes

If you are required to file a federal income tax return and do not, the IRS charges a failure-to-file penalty of 5 percent of the unpaid tax for each month or part of a month the return is late, up to a maximum of 25 percent of the tax owed. According to the IRS, this penalty begins accruing the day after the filing deadline and continues until the return is filed or the penalty reaches its cap. If your return is more than 60 days late, the minimum penalty is either $525 (for returns due in 2026) or 100 percent of the tax required to be shown on the return, whichever is less.

In addition to the penalty, the IRS charges interest on the unpaid balance starting from the original due date. According to the IRS, interest compounds daily and is based on the federal short-term rate plus 3 percent. Unlike penalties, interest does not have a maximum cap and continues to accrue until the balance is paid in full. The combination of penalties and interest means that the longer you wait to file, the more the total amount you owe grows.

Filing a return on time is important even if you cannot afford to pay the taxes you owe. The failure-to-file penalty is ten times more expensive per month than the failure-to-pay penalty, so filing without paying is far less costly than not filing at all.

What Happens If You File But Do Not Pay

If you file your return on time but do not pay the full amount owed, the IRS charges a failure-to-pay penalty of 0.5 percent of the unpaid tax for each month or part of a month the balance remains outstanding, up to a maximum of 25 percent. According to the IRS, this penalty is significantly smaller than the failure-to-file penalty, which is why filing on time, even without payment, is always the better choice. If you set up an approved installment agreement with the IRS, the failure-to-pay penalty is reduced to 0.25 percent per month for the duration of the agreement.

Interest also accrues on the unpaid balance starting from the original due date, just as it does for unfiled returns. According to the IRS, 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 amount of the failure-to-pay penalty, resulting in a combined penalty of 5 percent per month rather than 5.5 percent.

How Failure To File And Failure To Pay Penalties Compare

The failure-to-file penalty is ten times more expensive than the failure-to-pay penalty on a monthly basis, which makes filing your return the single most important step you can take to limit the financial damage of a late or unpaid tax obligation.

• Failure to file: 5 percent of unpaid tax per month, up to 25 percent maximum.
• Failure to pay: 0.5 percent of unpaid tax per month, up to 25 percent maximum.
• Both combined in the same month: the failure-to-file penalty is reduced by the failure-to-pay amount, resulting in a net 5 percent per month.
• Minimum penalty after 60 days late: $525 or 100 percent of the tax owed, whichever is less (for returns due in 2026).
• Interest: compounds daily at the federal short-term rate plus 3 percent, with no maximum cap.

According to the IRS, the bottom line is clear: if you cannot pay, file anyway. Filing the return stops the larger penalty from accruing and gives you access to payment options that can further reduce the failure-to-pay rate.

What The IRS Does When You Do Not File

If you fail to file your return voluntarily, the IRS can file a substitute return on your behalf, and this substitute return will not include any deductions, credits, or exemptions you may have been entitled to claim. According to the IRS, a substitute return is based solely on the income information the agency received from employers, banks, and other third parties. Because it does not account for deductions such as business expenses, student loan interest, or tax credits like the Earned Income Credit, the tax bill it generates is almost always higher than what you would owe if you had filed your own return.

After preparing a substitute return, the IRS sends a CP3219N (Notice of Deficiency), giving you 90 days to either file your own return or petition the U.S. Tax Court. If you do neither, the IRS proceeds with the assessment and the balance enters the collection process. According to the IRS, collection actions can include a federal tax lien filed against your property, levies on your wages and bank accounts, seizure of personal property, and garnishment of up to 15 percent of your Social Security benefits.

Can You Go To Jail For Not Filing Taxes

In extreme cases, the IRS can pursue criminal prosecution for willful failure to file a tax return, though this is rare and typically reserved for cases involving deliberate evasion or fraud. According to the IRS, willful failure to file a tax return is a misdemeanor under Internal Revenue Code Section 7203, punishable by up to one year in prison and a $25,000 fine for each year a return was not filed. Tax evasion, which involves intentionally concealing income or falsifying records to avoid paying taxes, is a felony under Section 7201 and carries a penalty of up to five years in prison and a $100,000 fine.

For most taxpayers who simply fell behind on their filing obligations, criminal prosecution is extremely unlikely. The IRS pursues criminal cases primarily when there is evidence of intentional fraud, large-scale evasion, or repeated willful refusal to comply. Voluntarily filing your past-due returns and cooperating with the IRS significantly reduces any risk of criminal referral.

How To Fix Unfiled Or Unpaid Taxes

The best way to resolve unfiled or unpaid taxes is to file all outstanding returns as soon as possible, pay what you can, and contact the IRS to set up a resolution for any remaining balance. According to the IRS, filing past-due returns stops the failure-to-file penalty from growing and is required before the agency will approve most payment arrangements. Taxpayers who need guidance on gathering records, requesting IRS transcripts, and completing returns for prior years can follow our step-by-step guide to filing back tax returns.

Once you have filed, you can address the balance using any of the options available to taxpayers who owe but cannot pay in full. Our guide to resolving IRS tax debt covers installment agreements, Offers in Compromise, Currently Not Collectible status, and penalty relief in detail. You may also qualify for first-time penalty abatement if you have a clean compliance history for the three prior tax years, which can eliminate the failure-to-file and failure-to-pay penalties for one tax period.

Taxpayers experiencing financial hardship may also qualify for the IRS Fresh Start program, which eases the eligibility requirements for installment agreements and expands access to lien relief for individuals working to get back into compliance.

How Many Years Can You Go Without Filing Taxes?

There is no statute of limitations on how far back the IRS can go for unfiled returns. According to the IRS, the agency generally requires you to file the last six years of returns to be considered in compliance, but it can pursue any unfiled year regardless of how long ago it was due.

Is There A Way To Get Penalties Removed?

Yes, the IRS offers penalty abatement for taxpayers who meet certain criteria. According to the IRS, first-time penalty abatement is available if you have filed and paid on time for the three prior tax years.
