Plain English
What is a federal tax lien?
A federal tax lien is a claim the IRS gets against everything you own when you do not pay a federal tax bill. It is not something an investor can buy. If you came here looking for tax liens to invest in, those are sold by counties, not by the IRS.

How is this different from the tax liens people invest in?
Different government, different tax, different rules. A federal tax lien belongs to the IRS and covers unpaid federal tax such as income tax. A property tax lien belongs to a county and covers unpaid property tax on one specific parcel.
Only the county kind is sold. Counties sell their claims to investors because they need the cash now and the tax is attached to a single property. The IRS does not sell its liens to the public at all. So if somebody is offering to sell you a federal tax lien, something is wrong.
When does a federal tax lien arise?
It happens by operation of law rather than by anybody filing a document. Under Internal Revenue Code section 6321, once the IRS assesses the tax, sends a demand for payment, and the taxpayer does not pay, the lien attaches automatically.
That means the lien can exist before you have seen any paperwork about a lien. The bill is the warning. The lien is what follows from ignoring it.
What is a Notice of Federal Tax Lien, and is it the same thing?
No, and this is the distinction almost every article blurs. The lien is the IRS claim. The Notice of Federal Tax Lien is the public document the IRS files to tell the world about it, usually with a county recorder or a state office.
The notice is what makes the claim visible to banks, buyers and anyone searching the record. Filing it also puts the IRS ahead of most creditors who come along afterwards. The lien exists either way; the notice is what other people can find.
How do I search for a federal tax lien?
You look where the notice is filed, which is public record. For real property that is normally the recorder, register of deeds or clerk in the county where the property sits. For business assets many states use a central filing office.
There is no single national IRS lookup for the public. Commercial search services aggregate the county and state filings, which is why they exist. If you are checking your own position, the IRS itself is the better source: it can tell you what is assessed and what is outstanding.
How long does a federal tax lien last?
Tied to how long the IRS has to collect, which under Internal Revenue Code section 6502 is generally ten years from the date the tax was assessed. When that collection period ends the lien becomes unenforceable and self-releases.
Ten years is the general rule and not a promise. Certain events, a bankruptcy, a collection due process appeal, an instalment agreement request or time spent abroad, can suspend or extend the clock. Check the dates on your own account rather than counting ten years from memory.
How is a federal tax lien released or removed?
Paying the full amount is the ordinary route. The IRS then issues a Certificate of Release of Federal Tax Lien, Form 668(Z), and it is supposed to do so within 30 days of the liability being satisfied or becoming unenforceable.
There are other routes with different effects, and the words matter. A withdrawal, requested on Form 12277, removes the public notice as though it had never been filed. A discharge removes the lien from one specific piece of property. A subordination lets another creditor move ahead of the IRS, which is often how a refinance gets done. Release, withdrawal, discharge and subordination are four different things.
Does a federal tax lien affect my credit?
Not on your consumer credit report, not any more. The three main credit bureaus stopped including tax liens on consumer credit reports, so a lien will not show up as a line item or move your score the way it once did.
That is not the same as invisible. The Notice of Federal Tax Lien is still public record, and lenders, title companies and anyone doing proper diligence can and do find it. It can still stop a house sale or a refinance.
Putting real numbers on it
The two kinds side by side, with real figures
- A federal tax lien: the IRS claim over everything the taxpayer owns, for unpaid federal tax. Not for sale, at any price.
- A county property tax lien, 3333 Brothers Pl SE, Washington DC: $1,010.99, of which $434.37 is the unpaid property tax and $576.62 is penalties and fees.
- That DC claim was sold. The District bid it off to itself in August 2026, and an investor can now buy it over the counter, which here means directly from the government with no auction and no bidding against anyone.
- A Lake County, Florida certificate from live county inventory: $200.49, paying up to 18 percent a year.
If what you want is the second sort, you are in the right place and the wrong page. We track county-held liens and deeds across 22 states. If what you have is the first sort, the IRS is who to deal with, and a tax professional is usually worth the fee.
What goes wrong
- You confuse the lien with the notice. The IRS claim exists from assessment and non-payment. The Notice of Federal Tax Lien is the later public filing. Waiting for a notice before acting wastes the time you had.
- You assume ten years and stop worrying. The collection period can be suspended or extended, so your actual date may be later than you think.
- You pay in full and assume the record clears itself. Check that the Certificate of Release was issued and recorded. An unreleased notice still shows up in a search years later.
- You ask for the wrong remedy. Release, withdrawal, discharge and subordination do different things, and asking for the one that does not fit your situation costs months.
- You think it no longer matters because credit reports dropped it. It is still public record, and a title company will find it before your sale closes.
- Somebody offers to sell you a federal tax lien. Nobody can. The IRS does not sell its liens to investors. Walk away.

Frequently asked questions
Can you buy a federal tax lien?
No. The IRS does not sell its tax liens to the public. The tax liens investors buy are property tax liens sold by counties, which are a different claim under different law. Anyone offering to sell you a federal tax lien is not selling what they say they are.
What is the difference between a federal tax lien and a property tax lien?
A federal tax lien is the IRS claim against everything a taxpayer owns for unpaid federal tax, and it is not for sale. A property tax lien is a county claim against one specific parcel for unpaid property tax, and counties do sell those to investors with statutory interest attached.
How long does a federal tax lien last?
It generally follows the IRS collection period, which under Internal Revenue Code section 6502 is normally ten years from assessment, after which the lien becomes unenforceable and self-releases. Certain events can suspend or extend that period, so verify the dates on the specific account.
How do I find out if there is a federal tax lien on a property?
Search the public record where the Notice of Federal Tax Lien would be filed, usually the county recorder, register of deeds or clerk for the county where the property is, and the state filing office for business assets. There is no single public IRS database.
What is a Certificate of Release of Federal Tax Lien?
It is the IRS document, Form 668(Z), confirming the lien has been satisfied or has become unenforceable. The IRS is required to issue it within 30 days of that happening. Keep a copy and confirm it was recorded where the original notice was filed.
Does a federal tax lien show up on my credit report?
Not on consumer credit reports. The major credit bureaus removed tax liens from them, so it will not appear as a line item or affect your score the way it used to. The notice remains public record, and lenders and title companies still find it.
