What a CP71C is
A CP71C is the IRS's annual reminder of an unpaid balance, carrying the passport certification warning. The notice's headline is the same as a CP71's — "Annual reminder of balance due taxes" — and the IRS describes it as arriving because "you still have an unpaid balance on one of your tax accounts and it requires your immediate attention."
Everything on a CP71 is true of this letter too. It is a reminder the IRS says it is required to send, it prints an amount and a date, it names payment, a payment plan, an offer in compromise, lien filing and levy, and it says it will keep arriving "until the statute of limitations for collection expires." It also carries the sentence people miss on both versions: "We'll assume you agree with the information in this notice if we don't hear from you." It is a restatement rather than an escalation — but it is not a letter with nothing on it.
The one paragraph that makes it different is the passport paragraph, and the letter sets out the statutory background in full:
"On December 4, 2015, as part of the Fixing America's Surface Transportation (FAST) Act, Congress enacted Section 7345 of the Internal Revenue Code (IRC), which requires the Internal Revenue Service to notify the State Department of taxpayers certified as owing a seriously delinquent tax debt. The FAST Act generally prohibits the State Department from issuing or renewing a passport to a taxpayer with seriously delinquent tax debt."
And then the notice does something better than most IRS letters do: it gives you the definition.
"Seriously delinquent tax debt means an unpaid, legally enforceable federal tax debt of an individual totaling more than [threshold] that has been assessed and for which a Notice of Federal Tax lien has been filed and all administrative remedies under IRC Section 6320 have lapsed or been exhausted, or a levy has been issued."
That single sentence is the whole test, and it is on your letter. What it cannot tell you — because it is a statement of law rather than a statement about your account — is which of its three limbs applies to you. That gap is what the rest of this page is about.
(The dollar figure is redacted above deliberately. It is adjusted every January and older notices print older numbers — see the warning below.)
The three things that must all be true
"Seriously delinquent tax debt" is a defined term, and the definition has three parts. All three are required.
| # | The requirement | Is it likely true for you? |
|---|---|---|
| 1 | More than $66,000 for 2026 — legally enforceable, unpaid federal tax debt including assessed penalties and interest. Adjusted every year for inflation. | Check the current figure, not the one printed on an older letter. |
| 2 | A Notice of Federal Tax Lien has been filed and administrative remedies under section 6320 have lapsed or been exhausted — or a levy has been issued. | This is the one people miss. A filed lien is a specific event with its own letter. |
| 3 | The debt is not covered by an exception. | See below — two of them are ordinary arrangements. |
Requirement 2 is where most of the reassurance lives, and it is the limb the definition sentence buries in the middle of a long clause. A large balance with no filed Notice of Federal Tax Lien and no levy issued is not seriously delinquent tax debt, whatever the number. If a Notice of Federal Tax Lien had been filed against you, you would have received a Letter 3172, which carries its own appeal rights and its own thirty-day hearing window.
So the single most useful thing you can establish tonight is whether a lien has actually been filed. That is a fact about your account, not a judgment call, and it is free to check.
⚠️ A note on the figure, because it will catch people. The threshold is adjusted annually and it moves every January. Older CP71C letters — including the published specimen — print earlier figures. A number on a letter from a previous year is not the current threshold and should not be relied on. Take it from the IRS's own current page, or ask.

What certification does, and what it does not
Certification is the IRS telling the State Department. It is not the State Department taking anything.
What follows certification, generally: the State Department will not issue a new passport and will not renew an existing one.
What is discretionary and separate: revoking a passport you already hold, or limiting it to return travel. The IRS's language is that the State Department may do this. It is not automatic and it is not the ordinary case.
And if you apply while certified, the State Department generally holds the application open for a period before denying it, to give you time to resolve the debt — which is not on your notice and is worth knowing before you cancel anything.
The practical shape of it: for most people the real exposure is not a passport being taken. It is a renewal quietly failing at the wrong moment.
The ways out
There are two statutory exceptions under section 7345(b)(2), and they are worth stating exactly because they are the whole of the statute's list:
"(A) a debt being paid in a timely manner under an installment agreement under section 6159, or an offer in compromise under section 7122; and (B) a debt whose collection is suspended because a section 6330 due process hearing is requested or pending, or because a section 6015 innocent spouse election is made or relief requested."
Read exception (A) again, because it contains the answer for most people who reach this page. A payment plan you are keeping to takes the debt outside the definition entirely. Not a hardship argument, not an appeal, not a negotiation — an installment agreement.
Note what (A) does and does not cover. An installment agreement being paid on time, or an accepted offer in compromise, are both inside it. A pending offer is not — that sits on the IRS's administrative list below, which is a different kind of protection. And not everyone can get or keep an agreement; unfiled returns block one outright.
The IRS also publishes a further list, and it matters that this list is not in the statute. The IRS says it will not certify debt that is: in currently not collectible status, subject to a pending installment agreement or offer request, or belonging to an identity theft victim. It separately treats child support, FBAR penalties and debt under a Department of Justice settlement agreement as outside the definition.
Those are administrative practice, not statutory rights, and the difference is real. A statutory exception is something you can rely on. Administrative practice is what the IRS says it currently does. Both are useful; only one of them is a rule. Anyone presenting the full list as "seven statutory exclusions" is wrong — the statute has two.
What happens if you do nothing
On the letter itself: another one next year. A CP71C is not a step in a sequence and does not lead directly anywhere.
On the passport question: it depends entirely on requirement 2. If no Notice of Federal Tax Lien has been filed and no levy has issued, certification is not currently in play. If a lien has been filed and the administrative rights on it have lapsed, and the balance is over the threshold, certification is a live possibility and the balance is growing toward it either way.
And penalties and interest continue regardless. They do not pause because collection has gone quiet.
What to do
Step one, tonight, free, and it answers most of the question: find out whether a Notice of Federal Tax Lien has been filed against you. Requirement 2 is the hinge, and until you know the answer everything else is speculation. Your IRS account transcript shows it, and so does the public record in the county where you live.
1. Establish the lien position. See above. This is the whole ballgame.
2. If you are near or over the threshold and a lien is filed, get an installment agreement in place. That is exception (A) and it is the most reliable route out. ⚠️ On this page specifically, the online route is not available to you. The IRS's online application for a long-term payment plan requires that you "owe $50,000 or less in combined tax, penalties and interest, and filed all required returns." Every reader of this page is above the passport threshold and therefore above that ceiling. The route is Form 9465, Installment Agreement Request, by mail or by phone on 800-829-1040 — and at this balance the IRS will generally want a financial statement with it. The setup fee by phone, mail or in person with direct debit is $107. This is not a twenty-minute job and anyone telling you it is has not looked at the number.
3. If you cannot pay anything at all, currently not collectible status is on the IRS's own non-certification list. It is requested at the number on your notice or at 800-829-1040, and the IRS may ask for Form 433-F, or Form 433-A for wage earners and the self-employed. Three things travel with it and none are optional to know: penalties and interest keep accruing, a lien may still be filed, and the debt is not forgiven.
4. If you have travel booked, say so early. Timing changes what is worth doing, and it is the one fact that turns this from an administrative problem into a dated one.
5. If you are already certified and resolve the debt, reversal is not instant and it is not the same as having a passport. That is the subject of the CP508R page.
The part that is harder than it looks: requirement 2's second half — whether the administrative remedies on a filed lien have "lapsed or been exhausted." A lien that has just been filed, with a Collection Due Process hearing still available or already requested, does not meet the test. A lien filed three years ago with nothing done about it does. The same document, the same balance, and two opposite answers depending on dates and events that are nowhere on this notice.
Two things worth reading next, depending on where this goes. How IRS payment plans work covers what an agreement at this balance involves, which is not the online form. And if no payment is possible, hardship status explained covers the route that appears on the IRS's non-certification list.
