What It Is
Tax debt is an assessed balance you have not paid. It rarely starts as one event. It builds. A return you could not pay in April, a year you never filed, an audit or a CP2000 notice that added tax you did not expect. The original tax is rarely what makes a balance feel impossible. Penalties and interest do that, and they stack.
The IRS generally has three years from the date you file to assess more tax under Internal Revenue Code section 6501. That stretches to six years if you understated income by more than 25 percent, and it never closes on a year you never filed or on a fraudulent return. An unfiled year stays open against you for good.
How the Balance Grows
Two penalties run against an unpaid balance, and interest runs on top of both.
| Charge | Rate | Cap and authority |
|---|---|---|
| Failure to file | 5% per month | 25% maximum. Section 6651(a)(1) |
| Failure to pay | 0.5% per month | 25% maximum. Section 6651(a)(2) |
| Both in one month | 5% combined | 47.5% lifetime maximum. Section 6651(c) |
| Interest | Short-term rate plus 3% | Daily compounding, no cap. Sections 6601, 6621 |
Late filing costs ten times more per month than late payment. File on time even when you cannot pay a cent. That cuts the larger penalty to zero and leaves only the 0.5 percent monthly charge running.
What the IRS Can Do
The IRS does not levy out of nowhere. It sends a sequence of notices, each one louder than the last, and one of them carries a hard deadline. The final notice of intent to levy, the CP90, LT11, or Letter 1058, gives you 30 days to request a Collection Due Process hearing under section 6330. Miss it and you lose the hearing that comes before a levy. After the notices come three tools.
- A federal tax lien is a legal claim against everything you own, filed under section 6321. It does not take anything. It attaches, and it can wreck your ability to sell, refinance, or borrow.
- A levy takes. Under section 6331 the IRS can seize wages and bank accounts. A bank levy holds the funds for 21 days before the bank sends them, which is your window to fix it. A wage levy repeats every pay period until released.
- Passport certification under section 7345 can deny or revoke your passport once a seriously delinquent balance passes the yearly threshold, more than $66,000 for 2026. An approved payment plan, an accepted offer, or hardship status generally keeps you out of it.
A lien is a claim that secures the debt. A levy is the actual seizure. A lien says the government has a right to your property. A levy is the government taking it.
The 10-Year Clock
This is the single most important concept in tax debt, and most people never hear about it. The IRS generally has ten years to collect an assessed tax. The deadline is the Collection Statute Expiration Date, set by section 6502. The clock starts on the date the tax is assessed, not the date you filed or the year the income was earned. When it runs out, the debt is legally extinguished and the IRS can no longer collect.
The clock can pause. It stops while a bankruptcy is pending, while an offer in compromise is under review, and while a Collection Due Process hearing is open, then adds that time back. Pull your account transcript and find your date before you choose anything.
Two paths can settle the same debt. One pays it. The other runs out the clock through currently not collectible status while the statute keeps ticking. A debt with eight years left behaves nothing like a debt with eighteen months left.
Is This You?
- You owe a balance you cannot pay in full right now
- Penalties and interest have made it larger than the original tax
- You have years you never filed
- You are getting IRS notices and are not sure which ones matter
- A lien, levy, or wage garnishment has started or been threatened
Your First Moves
Before any resolution is possible, a few things have to happen, in order. Skipping them is how good cases go wrong.
- Create or log into your IRS online account and pull your account transcript for every year you might owe
- Pull your wage and income transcript to surface any income you forgot
- Find the assessment date on each transcript and count ten years to estimate your collection statute date
- List every unfiled year and check for a substitute return the IRS filed for you under section 6020(b), which uses no deductions and usually overstates the tax
- File every missing return. Filing compliance is the gate to every resolution, required under sections 6011 and 6012(a)
- Estimate what you can pay each month after basic living expenses, and total what you own

Your Options
Once you are filed and you know your numbers, you pick a path. There is no single best option. The right one depends on what you can pay, what you own, and how much time is left on the clock. Each option has its own page.
| Option | What it does, and when it fits |
|---|---|
| Installment Agreement | Pay the balance over time in monthly amounts. The most common resolution, and it stops active enforcement once accepted. Section 6159, Form 9465. |
| Offer in Compromise | Settle for less than the full balance when your assets and income show the IRS could not collect more. The most oversold option, and the wrong fit for most balances. Section 7122, Form 656. |
| Currently Not Collectible | Pause collection when paying anything would leave you short on basic living costs. Not forgiveness, but the clock keeps running while you pay nothing. IRM 5.16.1, section 6343. |
| Penalty Abatement | Remove failure to file and failure to pay penalties through first-time abate or reasonable cause. Interest charged on a removed penalty comes off too. IRM 20.1.1, section 6651. |
| Unfiled Returns | File the back years first. Nothing else is possible while returns are missing, and your own return usually beats the substitute the IRS filed. Section 6020(b). |
| Innocent Spouse Relief | Get relieved of tax understated on a joint return because of a spouse or former spouse, when you did not know and had no reason to know. Section 6015, Form 8857. |
