Haven't filed taxes in years? How to get back on track

IRS policy (Policy Statement 5-133 in the Internal Revenue Manual) generally limits enforcement of delinquent returns to six years, though the IRS can require more in some cases. In practice, filing the most recent six years usually brings you into compliance. Your circumstances — like income that was never reported to the IRS, or a pending investigation — can change that. The IRS's filing past due returns page explains the process.

If you didn't file and the IRS received W-2s or 1099s, it may have prepared a substitute for return (SFR). An SFR uses only the income it knows about, with the standard deduction and single filing status — no dependents, business expenses or credits. It usually overstates what you owe. You can still file your own original return for that year, which typically replaces the SFR assessment and can lower the balance substantially.

Request wage and income transcripts for each missing year through your IRS Online Account — see how to get IRS transcripts. These list W-2s, 1099s, 1098s and other forms the IRS received. Self-employed people also need bank statements and records of business expenses. Prior-year forms and instructions are on IRS.gov.

• Failure-to-file penalty: 5% a month up to 25% on any tax owed. If you're owed a refund, there's no penalty.
• Failure-to-pay penalty and interest continue on any balance.
• Refunds expire: you generally must claim a refund within three years of the original due date. Older refunds are lost, and the IRS may keep newer refunds to pay older balances.
• Collection clock: the 10-year collection statute starts only when tax is assessed — so not filing doesn't run out the clock.

First-time penalty abatement or reasonable cause relief may reduce penalties once you're filed. Estimate them with the penalty calculator.

Criminal prosecution for not filing is rare and typically involves willful evasion. Coming forward voluntarily before the IRS contacts you is viewed favorably. If you have serious exposure — large unreported income or offshore accounts — talk to a tax attorney before filing. For most people, the realistic consequences are penalties, interest and collection on the balance, which the relief programs on this site address.

The IRS generally expects the last six years of returns to be filed to consider you in good standing, although it can ask for more in some cases. You can usually get the income information you need by requesting a wage and income transcript for each year from your IRS Online Account; it lists W-2s, 1099s and other forms reported under your Social Security number. If the IRS already filed a substitute return for a year, filing your own return — with the deductions, credits and filing status you're entitled to — can reduce the assessed balance. Remember that refunds for years more than three years past the filing deadline generally can't be claimed, so filing late can mean forfeiting money owed to you. File the most recent years first if you need to show the IRS current compliance quickly, then work backward.

1. Request wage and income transcripts for the last six years.
2. Gather other income and expense records.
3. Prepare and file the missing returns (oldest refund-eligible years first if you're owed refunds).
4. Start current-year withholding or estimated payments so you don't fall behind again.
5. Once assessed, resolve any balance with a payment plan, Currently Not Collectible status or an Offer in Compromise.
6. Ask for penalty relief.
