What a CP71 is
A CP71 is an annual reminder that a balance remains unpaid, which the IRS states it is required to send. From the notice: "We're required to send you this annual reminder explaining the amount you still owe for your [year] Form 1040 taxes." The IRS's own page opens: "We sent you this notice because you still have an unpaid balance on one of your tax accounts and it requires your immediate attention."
What makes it different from the rest of this family is that it is not a step in the escalation. The CP14, CP501 and CP503 form a sequence in which each letter adds something. A CP71 restates, on a yearly cycle, and it says how long it will keep doing so: "If you don't pay the amount due or call us to make payment arrangements, we will continue to send you annual reminder notices of your balance due until the statute of limitations for collection expires."
That sentence is the most useful thing on the notice, and it points at the question the rest of this page is about.
The notice also carries the standing lien and levy language, in full:
"When you do not pay your tax debt, a federal tax lien arises as a claim against all your property. If you don't pay the amount due immediately or make payment arrangements, we can file a Notice of Federal Tax Lien (NFTL) publicly establishing our priority with your creditors and we may levy (subject to any applicable Collection Due Process rights)."
Two things about that sentence. The lien arising is automatic and invisible and has already happened; the Notice of Federal Tax Lien is the public filing, which is a separate event and is what affects credit. And "we may levy" is subject to Collection Due Process rights — before the IRS can levy wages or a bank account it must first send a Final Notice of Intent to Levy, which is a different letter carrying a hard thirty-day window.
Your clock
Two different periods, and only one of them is on the letter.
The date printed on your notice is a payment date. It is real — interest and penalties keep running past it — and it is not a statutory deadline. Nothing about this letter forfeits a right if you miss it.
The period that matters is the collection statute. The IRS generally has ten years from the date a tax was assessed to collect it. Each tax year on your account carries its own, so an account with four years on it has four separate dates.
"Generally" is doing real work. The IRS lists what suspends or extends the period: a pending installment agreement request, a pending offer in compromise, a request for a Collection Due Process hearing, an innocent spouse claim, bankruptcy, combat zone and military service, and continuous residence outside the United States for six months or more.
Three of those are things a taxpayer chooses to do. Requesting a hearing, applying for an offer, or asking for an agreement all lengthen the period the IRS has to collect. That is not a reason to avoid any of them — it is a trade. Anyone who recommends one of those routes to you without mentioning that it extends the clock, including us, is giving you half a picture.

What triggered it
An unpaid balance that has been on the account long enough to enter the annual cycle. The notice is generated because a balance exists and the collection period has not run out — not because anyone reviewed your circumstances this year.
A common assumption worth correcting, because it changes what people do. People often read the arrival of a quiet annual letter, in place of the louder ones, as evidence that the IRS has stopped pursuing them — that the account must be in hardship status or otherwise parked.
Sometimes that is true and it is not what the notice means. The IRS sends this reminder because it is required to, on any open balance, until the collection period expires. A CP71 tells you a balance exists and a clock is running. It does not tell you what status your account is in, and assuming a favorable one from the tone of a letter is how people find out the hard way.
What happens if you do nothing
Another CP71 next year, a larger balance, and four consequences the notice itself names. From the IRS's own list of what happens if you do not respond:
- Interest continues to accrue and additional penalties may apply.
- Future tax refunds may be offset until the balance is paid. This is the one people are most often surprised by, and it is the mechanism most likely to actually touch them.
- A Notice of Federal Tax Lien may be filed, which is the public document that affects credit.
- The State Department may revoke, or decline to issue or renew, a passport if you are certified as having seriously delinquent tax debt. (The certification test has three parts and a balance alone does not meet it — see CP71C.)
And one more, which is not on any list because it is a sentence rather than a consequence: "We'll assume you agree with the information in this notice if we don't hear from you." If the balance is right, that costs nothing. If it is wrong, silence is being read as agreement, every year.
What does not happen: nothing is seized on the strength of this letter. Before the IRS levies wages or a bank account it must send a Final Notice of Intent to Levy and Notice of Your Right to a Hearing, which carries a hard thirty-day window and the strongest appeal right in the process. A CP71 is not that letter.
What to do
Step one, and it takes about a minute: check the code in the top-right corner of your notice. If it reads CP71C, you are holding a different letter with a passport consequence attached, and that page is where the answer is. If it reads CP71, carry on here.
Then, in order of what is actually worth doing:
1. Find out how much of the collection period is left on each year. This is the question the notice raises and it changes what everything else is worth. A balance with eighteen months left is a different problem from the same balance with eight years left.
2. Confirm what status your account is actually in, rather than inferring one from the quiet. If you were told you are in Currently Not Collectible status, that is checkable. If nobody ever told you and the loud letters simply stopped, that is worth knowing too.
3. If the balance is wrong, say so this year rather than next. The notice treats silence as agreement, and each year of silence makes the correction harder to evidence.
4. If your circumstances have worsened and no status is in place, Currently Not Collectible is requested at the number on the notice or at 800-829-1040, and the IRS may ask for Form 433-F, Form 433-A for wage earners and the self-employed, or Form 433-B for businesses. Three things travel with it and none is optional to understand: penalties and interest keep accruing, a Notice of Federal Tax Lien may still be filed, and the debt is not forgiven — you still owe the full amount.
5. If a refund is due to you on a later year, expect it to be offset. That is on the IRS's own list and it is often how a dormant balance suddenly becomes real.
What is harder than it looks here is step 1, and specifically the suspensions. Collection statute dates are not printed on any notice. They are derived from assessment dates and then adjusted for every event in the account's history that paused the clock — and each pause has to be identified from a transaction code and measured. The dates people arrive with are usually wrong in the same direction: they have counted ten years from the year of the tax, rather than from assessment, and have not counted the suspensions at all.
Two things worth reading next, depending on where this goes. Currently Not Collectible status explains what it is and what it does not do — including the three things that keep running while it is in place. Hardship status explained covers how the financial picture is assessed.
