IRS Letter 3172 is the Notice of Federal Tax Lien Filing issued under IRC § 6320, informing taxpayers that the IRS has recorded a public legal claim against all current and future property. Michigan taxpayers have 30 days to file Form 12153 requesting a Collection Due Process hearing, which can suspend collection and preserve Tax Court appeal rights. Options include CDP hearings, lien withdrawal, discharge, subordination, and full debt resolution. Ayar Law represents taxpayers nationwide facing federal tax liens.
This guide explains exactly what the federal tax lien notice means, how it affects your property and credit in Michigan, what your IRS lien rights are under a 6320 hearing, and what you can do right now to protect yourself.
When you receive Letter 3172, the IRS is not asking you to pay. It is informing you that it has already filed a Notice of Federal Tax Lien (NFTL) in the public record. That distinction matters.
Earlier IRS letters warn you about unpaid taxes. Letter 3172 confirms that the government publicly recorded its legal claim against your property. It also starts a strict 30-day deadline to preserve your appeal rights.
Many taxpayers confuse the federal tax lien with the NFTL notice. The lien itself arises automatically after the IRS assesses a tax, sends a demand for payment, and the taxpayer fails to pay. The NFTL filing is the IRS making that claim public to creditors, lenders, and title companies.
You can see how Letter 3172 fits within the broader IRS collection sequence in this breakdown of what each IRS collection notice means.
Once Letter 3172 arrives, your window to act is already shrinking.
A federal tax lien arises automatically under Internal Revenue Code § 6321. The trigger is straightforward:
At that point, the lien attaches by operation of law. No lawsuit. No judge. No court order. The federal government holds collection powers that private creditors do not. Many taxpayers assume they would have been sued first. They would not. Unpaid balances escalate into lien filings on a predictable timeline, as outlined in ” What happens when you owe back taxes.
Once the lien exists, the IRS may file the NFTL to protect its priority against other creditors. In Michigan, the IRS typically files the NFTL with the county register of deeds where you own real property. For personal property, filings may also appear through the Michigan Secretary of State’s UCC system.
Here is what makes a federal tax lien unusually broad:
Every asset you accumulate after the NFTL filing remains subject to the IRS’s claim until the debt is resolved.
Since 2018, Equifax, Experian, and TransUnion removed tax liens from consumer credit reports. This leads many taxpayers to assume the NFTL no longer matters. That assumption is wrong.
The NFTL remains a searchable public record. Mortgage lenders, title companies, and underwriters check public records during due diligence. A clean credit score does not prevent the lien from surfacing during a refinance or sale. For Michigan homeowners, a title search on real property will reveal the NFTL, and most title insurers will not allow a closing to proceed unless the lien is resolved, discharged from the specific property, or otherwise addressed.
The lien’s priority position creates additional obstacles. Under federal law, the IRS typically holds senior priority over later creditors. That means:
In certain regulated industries, an IRS-filed lien can create complications with professional licenses or government contracts.
Every dollar earned and every asset acquired after the lien is filed remains subject to the IRS’s claim. The window immediately following Letter 3172 is the highest-leverage moment to act. The protections available today may not be available 31 days from now.

IRC § 6320 gives every taxpayer the right to a Collection Due Process (CDP) hearing when the IRS files an NFTL. Congress built this protection into the tax code specifically to check IRS collection power.
This protection is not automatic. You must act. From the date on Letter 3172, you have 30 days to submit Form 12153 (Request for a Collection Due Process or Equivalent Hearing) to the IRS Office of Appeals at the address listed on your notice. This is a hard statutory deadline, not a guideline. Miss it, and you permanently lose your right to a full CDP hearing.
A timely 6320 hearing request allows you to:
One of the most powerful protections: once a proper CDP request is filed, the IRS must generally suspend collection activity while Appeals reviews your case. A timely CDP request also preserves your right to petition the U.S. Tax Court if you disagree with the Appeals determination. That judicial backstop disappears if you miss the deadline.
If you miss the 30-day window but file within one year of the NFTL filing date, you may still request an equivalent hearing. It allows Appeals review, but you lose the right to seek Tax Court review if you disagree with the result. A late filing is better than no filing, but the protections are meaningfully weaker.
What you write in Form 12153 typically limits what can be addressed at the hearing. The arguments you raise in that form define the boundaries of your appeal. This is one of the strongest reasons to have a tax attorney draft the request rather than filing it alone.
Missing the CDP deadline is serious, but it is not the end of every option. You may still request an equivalent hearing within one year. Outside the hearing framework, administrative remedies remain available:
None of these carries an automatic suspension of collection. The IRS does not routinely grant extensions to the CDP deadline. A taxpayer who waits to see what happens typically forfeits their strongest leverage.
If no CDP or equivalent hearing request is filed, the IRS may continue escalating enforcement. A lien is a legal claim. A levy is the actual seizure of wages, bank accounts, or property. The 30-day window is about more than a hearing. It is about preserving the strongest set of legal tools at the moment when the taxpayer has the most leverage.
Filing Form 12153 within 30 days is the most powerful first move available. It preserves appeal rights, can suspend collection, and creates an opportunity to negotiate from a stronger position. Precision matters. The issues raised in the request define the scope of the hearing. This is not a form to fill out alone.
A withdrawal removes the Notice of Federal Tax Lien from the public record entirely. This is meaningfully different from a lien release, which simply confirms the debt was satisfied. Withdrawal erases the public filing as if it never existed, which can restore access to credit and remove barriers to property transactions. Withdrawal may be available if the lien was filed improperly, the debt is paid, or you qualify under certain installment agreement programs. Eligibility details and the full process are covered in our guide to negotiating a tax lien withdrawal.
If you need to sell or refinance Michigan property before the underlying debt is resolved, you may seek a discharge or subordination. A discharge removes the lien from a specific asset and clears the path to sell. Subordination clears the path to refinance. Our guide to tax lien discharge vs. subordination explains eligibility for each.
Full payment, qualifying installment agreements, and Offers in Compromise each create different timelines toward lien release. For eligibility factors and a full breakdown, see when removing a tax lien is possible.
Each option carries trade-offs. The right strategy depends on the amount owed, the accuracy of the assessment, your financial condition, and how much time remains before deadlines expire.
No. A lien is a legal claim against property. A levy is the actual seizure. Letter 3172 signals escalating collection activity, not immediate seizure. Filing a timely CDP hearing request generally pauses levy action during the appeal.
Tax liens no longer appear on consumer credit reports. The NFTL remains a public record, however. Lenders and title companies often discover it through public record searches, which can interfere with sales, refinances, and financing, even when credit scores are unaffected.
Under IRC § 6502, the IRS generally has 10 years from the date of assessment to collect. The lien typically runs with that collection statute, subject to extensions or tolling events. It does not expire without resolution.
A 6320 hearing allows you to challenge the underlying liability if you did not previously have an opportunity to contest it. That argument must be raised specifically in Form 12153. If you never received a notice of deficiency or never had a chance to dispute the amount, the CDP hearing may be your opportunity to do so.
Form 12153 is the IRS form used to request a CDP or equivalent hearing. It must be sent to the IRS Office of Appeals address listed on Letter 3172. The content of the form shapes the entire appeal. An attorney should review it before it is submitted.
Yes. The IRS can and does file NFTLs even when a taxpayer is in an installment agreement. Certain streamlined or direct debit agreements may create pathways to withdrawal depending on eligibility, which is another reason the type and terms of an agreement matter.
The 30-day CDP deadline triggered by Letter 3172 is one of the most consequential deadlines in IRS collections law. Missing it narrows your legal options and eliminates your right to judicial review. Ayar Law’s Michigan tax attorneys help clients request CDP hearings, negotiate lien withdrawals, obtain lien discharges and subordinations, and resolve the underlying tax debts that trigger NFTLs in the first place.
