Collection notice and Notice of Federal Tax Lien
tax year · reviewed 2026-08-18 · I. Ohu
The lien and the notice of lien are two different things, and almost every practical error in this area comes from treating them as one. The lien arises by operation of law the moment an assessment goes unpaid after demand. Filing a notice of it changes nothing between the taxpayer and the government — it changes the government’s position against third parties, and it is what gives the taxpayer a hearing right.
The rule
The lien arises without any filing. If a person liable for tax neglects or refuses to pay after demand, the amount — including interest, additions, assessable penalties and costs — is a lien in favour of the United States upon all property and rights to property, real or personal, belonging to that person (IRC § 6321). It attaches to everything the taxpayer owns and everything they later acquire while it runs.
When it starts and stops. Unless another date is fixed by law, the lien arises at the time the assessment is made and continues until the liability is satisfied or becomes unenforceable by reason of lapse of time (IRC § 6322). Nothing needs to be recorded for it to exist.
What filing the notice does. The § 6321 lien is not valid against a purchaser, holder of a security interest, mechanic’s lienor, or judgment lien creditor until a notice meeting § 6323(f) has been filed (IRC § 6323(a)). Filing is therefore about priority against four classes of third party, not about the taxpayer’s liability. Even after filing, the lien remains invalid against certain interests — securities purchased without actual notice, and the other superpriorities in § 6323(b).
Where it is filed. In the one office designated by state law for the county or subdivision where the property is situated; failing a state designation, with the clerk of the United States district court for that judicial district; and in the District of Columbia with the Recorder of Deeds (IRC § 6323(f)(1)).
Refiling. Unless refiled during the required refiling period, a notice loses its original filing date and is treated as filed on the later date. The required refiling period is the one-year period ending 30 days after the expiration of 10 years from the date of assessment, and each 10-year period after thatTY2026 (IRC § 6323(g)(1), (3)).
The hearing right. Filing the notice triggers a collection due process right. The IRS must notify the taxpayer within 5 business days after the notice of lien is filed, with the 30-day hearing window opening the day after that periodTY2026, and the notice must state the amount, the right to request a hearing, the administrative appeals available, the release provisions, and the § 7345 passport certification consequences (IRC § 6320(a)(2), (a)(3)).
Getting out. Four different things, often confused:
- Release — the Secretary shall issue a certificate of release not later than 30 days after the liability is satisfied or becomes legally unenforceable, or a bond is acceptedTY2026 (IRC § 6325(a)).
- Discharge — removes specific property from the lien, leaving the lien otherwise intact (IRC § 6325(b)).
- Subordination — lets another creditor take priority over the lien as to identified property (IRC § 6325(d)).
- Withdrawal — treats the notice as if it had never been filed, available where filing was premature or contrary to procedures, where the taxpayer has entered a § 6159 installment agreement, where withdrawal will facilitate collection, or where the taxpayer or the National Taxpayer Advocate consents and it is in the best interests of both (IRC § 6323(j)(1)). On written request, the IRS must make reasonable efforts to notify credit reporting agencies and named creditors (IRC § 6323(j)(2)).

How it works in practice
The distinction that matters to a client is that the lien already exists. A taxpayer who says “they put a lien on me” usually means a notice was filed and their credit or a pending sale is affected. The lien attached at assessment; what changed is the government’s standing against buyers and lenders. That framing decides which remedy to pursue, because discharge, subordination and withdrawal each address a different problem.
Withdrawal is the one worth knowing cold, because it is the only remedy that erases the filing itself, and because § 6323(j)(1)(B) makes an installment agreement an express ground. A client whose complaint is the recorded notice — not the tax — has a statutory route that most do not know exists, and § 6323(j)(2) obliges the IRS to notify credit agencies on written request. Release, by contrast, leaves the filing history in place; the debt is gone, but the record of it is not withdrawn.
Discharge and subordination solve transactions. A client selling a house does not need the lien released; they need the property discharged so the sale can close, or the lien subordinated so a refinancing lender can take first position. Asking for a release in either case gets a refusal that looks like obstruction and is actually a category error.
The refiling rule is a quiet trap on old liabilities. A notice not refiled in its window keeps the lien alive but loses its priority date, so an intervening purchaser or lender may outrank it. On a file older than ten years the refiling history is worth checking before advising a client that the government stands first.
The sale that could not close
A client under a filed notice of lien has a buyer for her house. The equity after the mortgage is $40,000 and the tax liability is $180,000. Her agent tells her the sale is impossible until the lien is released.
Analysis. The agent has the wrong remedy. Release under § 6325(a) requires the liability to be satisfied or unenforceable, which it is not. What the transaction needs is a discharge of the specific property under § 6325(b), which removes the house from the lien while leaving the lien on everything else. The government typically takes the net equity from the closing. The sale can proceed; asking for the wrong certificate is what stops it.
The notice that should not have been filed
A taxpayer entered an installment agreement in March. In May, a notice of federal tax lien is filed against him because a systemic filing criterion was met. His agreement is current and he is meeting every payment.
Analysis. Section 6323(j)(1)(B) makes entry into a § 6159 installment agreement an express ground for withdrawal of the notice, unless the agreement provides otherwise. Withdrawal means the chapter applies as if the notice had never been filed — better than release. On written request the IRS must make reasonable efforts to notify credit reporting agencies (§ 6323(j)(2)), which is the point of the exercise for most clients.
Counting the hearing window
A notice of federal tax lien is filed on Monday 6 April. The Letter 3172 is mailed on Thursday 9 April. The client brings it in on 20 May and asks whether he can still request a hearing.
Analysis. The window is not measured from the letter. Section 6320(a)(2) requires notice within five business days of filing, and § 6320(a)(3)(B) gives the right to request a hearing during the 30-day period beginning the day after that five-business-day period. From a Monday 6 April filing, the five business days close on 10 April and the 30 days run from 11 April to 10 May. A request on 20 May is out of time for CDP; an equivalent hearing may still be available, but Tax Court review is lost.
Traps
The lien is not the notice. The lien arises at assessment under § 6321; the notice affects priority against third parties under § 6323(a).
Release, discharge, subordination and withdrawal are four remedies, and only withdrawal treats the notice as never filed.
An installment agreement is a statutory ground for withdrawal. IRC § 6323(j)(1)(B).
The CDP clock runs from the filing, not from the letter — five business days, then thirty.
Filing does not defeat every third party. The § 6323(b) superpriorities survive it.
A missed refiling costs priority, not the lien. The lien survives; its date does not.
How this has changed
The lien provisions took their modern shape in the Federal Tax Lien Act of 1966 (Pub. L. 89-719), which rewrote §§ 6322 to 6325 and built the priority scheme in § 6323 that still governs. The two later layers matter more in practice. The withdrawal power in § 6323(j), including the installment agreement ground and the obligation to notify credit reporting agencies on request, came from the Taxpayer Bill of Rights 2 and the Restructuring and Reform Act of 1998, which also added the § 6320 CDP right on filing. Most recently, § 6320(a)(3)(E) now requires the notice to explain the § 7345 passport certification consequences of seriously delinquent tax debt.
Exam focus
Separate the lien from the notice, and be able to say what filing achieves. Know the four classes in § 6323(a) that filing defeats. Know all four exit routes and which one each fact pattern needs — especially that a sale needs discharge and a refinancing needs subordination. Know that an installment agreement supports withdrawal. Count the CDP window correctly: five business days from filing, then thirty days beginning the day after. Expect the release deadline in § 6325(a) as a discrete fact.
