IRS Notices When You're Overdue: Every Letter and Deadline

When you owe tax and don't pay, the IRS mails a fixed series of notices: CP14 (balance due), CP501 and CP503 (reminders), CP504 (notice of intent to levy), then LT11 or Letter 1058 (final notice before levy, with a 30-day window to request a hearing). The whole sequence usually takes several months. Each letter raises the stakes, and penalties and interest grow the balance the entire time.

This guide walks through each notice in order, the deadline printed on it, what the IRS can do next, and the cheapest way to respond at each step. Figures are current for late 2026.

The IRS overdue notice timeline at a glance

The IRS does not publish one official calendar. The intervals below come from an IRS and Taxpayer Advocate Service presentation at the 2024 IRS Nationwide Tax Forum, and they describe typical timing for individual accounts.

Two timing rules apply to most bills. You generally have 21 calendar days from the notice date to pay before more penalty accrues, or 10 business days if you owe $100,000 or more (IRS, failure to pay penalty). And the IRS has 10 years from the date it assessed the tax to collect it (26 U.S.C. 6502), though some actions pause that clock.

Stage 1: The first bill (CP14)

What a CP14 notice means

A CP14 tells you that you owe unpaid tax and shows the amount, including penalties and interest added so far. It usually arrives after you file a return without paying the full balance. The IRS must send this first notice and demand for payment within 60 days of assessing the tax.

If you live in a federally declared disaster area, you may get a CP14C instead, which gives automatic extra time.

What to do with a CP14

•         Check the amount against your return. If you disagree, call the number on the notice with your records ready.

•         Pay in full by the due date if you can. That stops further interest and penalty.

•         If you can't pay in full, set up a payment plan now. A short-term plan of up to 180 days has no setup fee if you owe less than $100,000 (IRS payment plans).

You can view the notice and your balance in your IRS online account.

Stage 2: The reminders (CP501 and CP503)

CP501: first reminder

A CP501 is a reminder that the balance is still unpaid after the first notice. The IRS warns that it may file a Notice of Federal Tax Lien if you don't act. Your options are the same as at CP14: pay, request a payment plan online or with Form 9465, correct the return with Form 1040-X if it was wrong, or request a Collection Appeals Program review if you dispute a coming collection action.

CP503: second reminder

A CP503 is "your second reminder that you still owe a balance." It carries the same lien warning. This is the last notice before the IRS formally states it intends to levy, so it is a good point to settle on a plan.

The IRS paused CP501, CP503 and CP504 for nearly two years during its pandemic backlog and resumed them in October 2023. Interest and penalties kept accruing during the pause (Taxpayer Advocate Service). If you have an older balance and few letters, the debt has still been growing.

Stage 3: Notice of intent to levy (CP504)

A CP504 is the IRS's notice of intent to levy under section 6331(d) of the tax code. The IRS calls it a final reminder before collection.

The IRS may take your state income tax refund first. The CP504 also lists what can follow: levies on wages, commissions, bank accounts, business assets, personal property such as a car or home, and Social Security benefits. It warns that a lien may be filed and that seriously delinquent debt can affect your passport.

A CP504 does not by itself start a wage or bank levy. Before most of those levies, the IRS must send a final notice with hearing rights (Stage 4). But the CP504 changes the cost of waiting: if you don't pay within 10 days of a notice of intent to levy, the failure-to-pay penalty rises from 0.5% to 1% a month (IRS).

Stage 4: Final notice and your right to a hearing (LT11, Letter 1058 or CP90)

What the final notice means

LT11 and Letter 1058 tell you the IRS intends to seize property and that you have the right to a Collection Due Process (CDP) hearing. A CP90 carries the same hearing rights for certain levies. The listed targets include wages, bank accounts, business and personal assets, state refunds, Social Security benefits and, for Alaska residents, the Permanent Fund Dividend.

The IRS generally must send this final notice at least 30 days before it levies (Publication 594).

The 30-day hearing deadline

To request a CDP hearing, file Form 12153 within 30 days of the notice date. The Taxpayer Advocate Service puts it plainly: "This deadline cannot be extended for any reason" (TAS, Letter 11).

A timely request usually stops levy action while IRS Independent Office of Appeals reviews your case. At the hearing you can propose a payment plan, an offer in compromise or hardship status, or dispute the debt if you had no earlier chance. If you disagree with the Appeals decision, you can petition the U.S. Tax Court within 30 days of it (TAS, CDP). A CDP request also pauses the 10-year collection clock.

If you miss the 30 days, ask for the equivalent hearing rather than doing nothing.

Lien and passport notices (Letter 3172 and CP508C)

Letter 3172: a lien was filed

A federal tax lien arises by law once you don't pay the first bill. When the IRS files a public Notice of Federal Tax Lien, it sends Letter 3172 within 5 business days. The lien attaches to your current and future property and stays until the balance is paid, the collection period ends, or an offer in compromise is accepted. You can request a CDP hearing on the lien with Form 12153 by the date in the letter.

A lien is a claim, not a seizure. A levy actually takes the money or property. Our guide to the difference between an IRS levy and a lien explains both.

CP508C: passport certification

If your debt is "seriously delinquent," the IRS can certify it to the State Department and send a CP508C. For 2026 the threshold is $66,000 in assessed tax, penalties and interest, up from $64,000 in 2025 (IRS, passport revocation or denial). The State Department can deny a new passport or revoke a current one, and it holds applications for 90 days so you can resolve the debt.

Debt is not certified, or is excluded, while it is on a timely paid installment agreement or accepted offer, during a timely CDP levy hearing, while an innocent spouse request is pending, in hardship status, or in bankruptcy. The IRS reverses a certification within 30 days after you resolve the debt.

Other notices you may get while you're overdue

Not every IRS letter is a step on the collection ladder. These are common ones that people mix up with it:

If a CP2000 or a 90-day letter is wrong, answering it on time is how you avoid owing the extra tax in the first place.

What waiting costs in 2026

Every month you wait adds to the balance. These are the IRS figures for late 2026:

As an illustration, on a $10,000 unpaid balance the failure-to-pay penalty adds $50 a month, and interest at 7% adds a little over $700 in a year. Filing your return on time, even when you can't pay, avoids the much larger failure-to-file penalty.

How to respond at each stage

Pay in full or use a payment plan

A payment plan is the most common fix, and you can set one up online without waiting for the next letter. The IRS payment plan fees for 2026:

To apply online for a long-term plan, you must owe $50,000 or less and have filed all required returns. Low-income taxpayers, with adjusted gross income at or below 250% of the federal poverty level, get the direct-debit fee waived and pay $43 otherwise, which may be reimbursed. Penalties and interest keep accruing on any plan, at the reduced 0.25% penalty rate if you filed on time. Our guide to how an IRS payment plan works covers the steps.

Offer in compromise

An offer in compromise settles the debt for less than you owe when paying in full isn't realistic. The 2026 application fee is $205, and a lump-sum offer requires 20% of the offer amount up front. Low-income applicants are exempt from both. You must have filed all returns and can't be in an open bankruptcy. The IRS has a free Pre-Qualifier tool to check eligibility first. See how an IRS offer in compromise works.

Currently Not Collectible status

If paying anything would leave you unable to meet basic living costs, you can ask the IRS to delay collection by calling the number on your notice. The IRS may ask for a financial statement (Form 433-F, 433-A or 433-B). The debt isn't forgiven, interest and penalties continue, the IRS may still file a lien and keep your refunds, and it can resume collection if your finances improve.

Penalty relief

If something outside your control, such as a serious illness or disaster, caused you to pay late, you can ask the IRS to remove penalties for reasonable cause. Taxpayers with a clean recent record may also ask about first-time abatement.

Get help if it's complicated

The Taxpayer Advocate Service (877-777-4778) is a free, independent office inside the IRS that helps when a tax problem is causing hardship or the normal channels haven't worked. You can also authorize a CPA, enrolled agent or attorney to deal with the IRS for you using Form 2848. If your balance is large, our guide to owing the IRS more than $25,000 explains what changes at higher balances.

How to tell a notice is really from the IRS

Scammers copy IRS letters, so check before you pay. The IRS usually makes first contact by regular mail. It sends email or texts only if you opted in, and it never contacts you through social media direct messages (IRS, how to know it's really the IRS).

To verify a letter:

1.       Look up the notice number in the IRS notice search on IRS.gov.

2.       Log in to your IRS online account and confirm the notice and balance appear there.

3.       Pay only through IRS.gov or to the "United States Treasury."

4.       Treat threats, pressure or demands for immediate payment by an unusual method as warning signs.

If your account is assigned to a private collection agency, the IRS tells you first by letter, and that letter includes a 10-digit Taxpayer Authentication Number (Publication 594).

Frequently asked questions

How many notices does the IRS send before it levies?

Usually four or five: CP14, CP501, CP503, CP504, and then the final notice (LT11, Letter 1058 or CP90) with your right to a hearing. The IRS generally must send that final notice at least 30 days before levying wages or bank accounts. It can take a state tax refund after the CP504.

How long does it take to go from CP14 to a final notice?

Several months. Based on IRS and Taxpayer Advocate guidance, CP501 comes about 8 weeks after CP14, CP503 about 8 weeks after that, and the final notice about 5 weeks after CP504. The gap before CP504 isn't fixed.

What happens if I ignore IRS notices?

The balance keeps growing from penalties and interest, the IRS may file a public tax lien, and after the final notice it can levy your wages, bank accounts or other property. Seriously delinquent debt over $66,000 in 2026 can also lead to passport denial.

Can I still get a payment plan after a final notice?

Yes. You can request one online if you qualify, or raise it at a Collection Due Process hearing. Installment agreements require that your required returns are filed.

Is a CP2000 a bill?

No. A CP2000 proposes changes to your return based on income reported by others. You need to respond by the date on the notice to agree or disagree. If you don't respond, the IRS may send a bill for the proposed amount.

Next steps

Open every IRS letter, note the date on it, and act before the deadline, especially the 30-day window on a final notice. If you need help comparing a payment plan, an offer or hardship status, see our IRS notices and letters page.
