What Happens If You Don't File Your Taxes?
Last reviewed by Calculus Tax in-house Settlement Officer
If you don't file a required tax return, the IRS can charge a failure-to-file penalty, hold and eventually lose your refund, prepare a substitute return without your deductions, and then bill and collect the tax. Repeatedly failing to file can also lead to additional penalties or criminal prosecution. Filing as soon as possible limits the damage.
Quick answer
If you don't file a required return, the IRS can charge a failure-to-file penalty of generally 5% of the unpaid tax per month, up to 25%, plus interest and late-payment penalties. It may also hold your refund, prepare a substitute return without your deductions, and then bill you and collect the tax through liens or levies.
| Failure-to-file penalty | Generally 5% of unpaid tax per month, up to 25% |
|---|---|
| Failure-to-pay penalty | 0.5% per month, up to 25% |
| Refunds | Held while returns are past due; generally lost after 3 years |
| Substitute return | May not include your deductions and exemptions |
| After a CP3219N | 90 days to file your return or petition the Tax Court; no extension |
| Processing a past-due return | About 6 weeks, per the IRS |
The Failure-to-File Penalty
The failure-to-file penalty is generally 5% of the unpaid tax for each month the return is late, up to 25%. If you also did not pay, the failure-to-pay penalty adds 0.5% per month, up to 25%, and interest is charged at the federal short-term rate plus 3 percentage points, compounded daily. Filing on time, even without paying, avoids the larger of the two penalties.
If You Are Owed a Refund
Because penalties are based on unpaid tax, a year where you are owed a refund generally has no failure-to-file penalty. But the IRS holds refunds when its records show a past-due return, and you generally must file within three years of the due date to claim a refund. After that, the refund is generally lost.
The IRS May File a Substitute Return
If you do not file, the IRS may prepare a substitute return using income reported by employers and other payers. That return might not give you credit for deductions and exemptions you are entitled to. The IRS then sends a Notice of Deficiency, CP3219N, proposing the tax. See the IRS substitute for return guide.
The 90-Day Window
After a CP3219N, you have 90 days to file your past-due return or petition the Tax Court. If you do neither, the IRS proceeds with its proposed assessment. You cannot request an extension to file once you have received a CP3219N.
Collection: Liens and Levies
The assessment becomes a tax bill. If it goes unpaid, the IRS collection process can include a levy on your wages or bank account and a Notice of Federal Tax Lien. Learn how the notices escalate in how the IRS collection process works.
Effects on Social Security and Loans
If you are self-employed and do not file, your self-employment income is not reported to the Social Security Administration, so you do not earn credits toward Social Security retirement or disability benefits. Loan approvals may also be delayed, because lenders ask for copies of filed returns or IRS transcripts.
Criminal Risk
The IRS warns that if you repeatedly do not file, you could face additional enforcement, including more penalties or criminal prosecution. Willfully failing to file is a misdemeanor under IRC section 7203. Read can you go to jail for not filing taxes for what that means.

Frequently Asked Questions
Is there a penalty for not filing if I do not owe anything?
Generally no failure-to-file penalty, because it is based on unpaid tax. But your refund may be held, and it is generally lost if you do not file within three years of the due date.
How long can I go without filing before the IRS does something?
There is no fixed time. The IRS receives W-2 and 1099 information from payers and may send notices, prepare a substitute return, and start collection.
Will the IRS file my taxes for me?
It may prepare a substitute return using third-party income records, which might not include your deductions. You can still file your own return, and the IRS will generally adjust your account.
Should I file if I cannot pay?
Yes. The IRS says to file all returns that are due whether or not you can pay. Then use a short-term plan, an installment agreement, or another option for the balance.
What if I have not filed in many years?
The IRS normally asks for the last six years. See how far back the IRS goes for unfiled returns.
How do I get my income information for old years?
Request wage and income transcripts in your IRS Online Account or with Form 4506-T. They are available for the current and nine prior years.
