What Publication 1450 is
Publication 1450 is the IRS's instruction sheet for requesting a Certificate of Release of Federal Tax Lien. Its full title is "Instructions for Requesting a Certificate of Release of Federal Tax Lien."
It is a publication, not a notice, which is worth saying plainly because people search for it as one. The IRS does not send it the way it sends a CP or an LT. It is instructional matter that travels with the lien paperwork, and it is where the mechanics of getting a lien released are actually written down.
If you are looking for it because a lien was filed and you want to know what happens next, the letter that reported the filing is Letter 3172 and that is the page for the hearing rights and the deadlines. This page is for the other end of the problem: the balance is dealt with, and you want the lien gone.
Your clock — and it is not yours
The IRS has 30 days. You have none.
Section 6325(a)(1) is mandatory language: the Secretary "shall issue a certificate of release of any lien imposed with respect to any internal revenue tax not later than 30 days after the day on which" the liability is satisfied or becomes legally unenforceable. The IRS says the same thing in plainer words: "The IRS releases your lien within 30 days after you have paid your tax debt."
We are pointing at the direction of the arrow because readers assume every deadline in a tax letter is one they can miss. This one is a duty owed to you. If it is day 25 and nothing has arrived, you are not late.
Two things shorten or change it:
Guaranteed funds. Publication 1450: "Should there be an unpaid balance on your liability, you must pay the balance with guaranteed funds for the Certificate of Release to be immediately issued." Guaranteed funds are a certified check, a cashier's check, an official bank check, or an acceptable money order. Read the sentence as it is written — it is a requirement for getting immediate issuance, not a description of what happens to everyone who once paid by money order.
The second limb of the statute. Release is required when the liability "becomes legally unenforceable," which is what happens when the collection period expires. The IRS generally has ten years from assessment to collect — longer where a pending offer, a timely CDP request, an innocent spouse claim or a bankruptcy suspended it. On an old lien with no money behind it, that sentence is the whole answer, and it is the one almost nobody publishes.

What happens on its own, and what does not
A Notice of Federal Tax Lien generally self-releases when the collection period expires. The Taxpayer Advocate Service puts it this way: "The lien is generally released automatically (self-released), or the IRS can file a certificate of release prior to it self-releasing."
Carry the word generally, because the exception is the reader most likely to be relying on this. Self-release operates off a date printed on the lien notice itself. A collection period that has been suspended or extended — by a pending offer in compromise, by a timely Collection Due Process request, by bankruptcy — runs past that printed date, and the lien does not fall away when the paper suggests it will.
So: the release is automatic, the date on the paper is not necessarily the date, and the difference is on your transcript rather than on the lien notice. If you are planning around a self-release, that is the document to check.
How to ask for the release
- Confirm the balance is actually satisfied — all of it, all periods. A lien notice can cover several periods. A payoff that clears three of four leaves the lien standing on the fourth, and the certificate cannot issue.
- Put the request in writing. Publication 1450 directs a written request to the Collection Advisory Group for your area. Publication 4235 lists the addresses.
- Or call the Centralized Lien Operation. 800-913-6050, or 859-320-3526 from outside the United States. This is the unit that handles lien releases and it is the fastest route to finding out where yours is. The IRS's current e-fax for that unit is 855-390-3530 — Publication 1450's older revision prints 855-753-8177, so use the live number and ring if a request already went to the older one.
- If you need it urgently, go in person. Publication 1450: "If you have an immediate or urgent need for a Certificate of Release of Federal Tax Lien, you can visit or telephone the local IRS office." Take proof of payment.
- Check what the certificate says before you rely on it. The certificate of release extinguishes the lien — section 6325(f)(1). It does not erase the filed notice from the public record. What the record then shows is a lien that has been released, which is not the same as no lien ever having been filed.
- If the record itself is the problem, you are asking for a withdrawal, not a release. A release ends the lien; a withdrawal removes the notice from the record. If a lender reading the file or an application that keeps stalling is what is costing you, that is a withdrawal question.
- If you get a withdrawal, ask for the notifications — in writing. Section 6323(j)(2) says that on written request the IRS "shall promptly make reasonable efforts to notify credit reporting agencies, and any financial institution or creditor whose name and address is specified in such request." The IRS does not do this unprompted. Name the lender. Name the bureaus. Put it in the letter.
| You want | Ask for | What you get |
|---|---|---|
| The lien to end | Release | The lien is extinguished; the record shows a released lien |
| The public notice gone from the record | Withdrawal | The notice comes off; the liability can remain |
| One property freed | Discharge | That property comes out; the lien continues elsewhere |
| A lender ahead of the IRS | Subordination | The lien stays; the named creditor goes first |
