When the IRS files a Notice of Federal Tax Lien, it has to tell you, and it has to offer you a hearing. That notice is usually Letter 3172, Notice of Federal Tax Lien Filing and Your Right to a Hearing Under IRC 6320.

The lien CDP hearing is a cousin of the levy hearing under IRC 6330. Same Appeals office, same Tax Court review. But the trigger, the timing, and the practical stakes are different. Here is how it works, procedurally.

The notice and its timing

IRC 6320(a) requires the IRS to notify you in writing of the lien filing. The notice must be given in person, left at your home or business, or sent by certified or registered mail to your last known address, not more than five business days after the day the lien notice is filed.

The hearing window is not 30 days from the date on the letter. IRC 6320(a)(3)(B) gives you the 30-day period beginning on the day after the end of that five-business-day period. In other words, the clock is tied to the filing date, not to when you opened the envelope. The letter should state the deadline. Use that date, and do not assume you have 30 days from receipt.

Like levy hearings, you get one lien CDP hearing per tax period (IRC 6320(b)(2)). A later lien filing for the same period in a different county does not create a new hearing right for that period.

How the hearing is conducted

IRC 6320(c) applies the levy hearing rules of IRC 6330(c), (d) (except (d)(3)(B)), (e), and (g). So the hearing has the same structure:

  • An impartial Appeals officer with no prior involvement (IRC 6320(b)(3)).
  • Verification that legal and administrative requirements were met.
  • Consideration of spousal defenses, challenges to the appropriateness of the lien, collection alternatives, and, where permitted, the underlying liability.
  • The balancing test of IRC 6330(c)(3)(C).
  • A Notice of Determination you can petition to the Tax Court within 30 days.

IRC 6320(b)(4) says lien and levy hearings should be held together to the extent practicable. If you have both notices and both windows are open, request both on one Form 12153.

What a lien hearing can and cannot stop

This is the part most people misread. The lien already exists. A federal tax lien arises by operation of law under IRC 6321 when tax is assessed, demand is made, and the tax goes unpaid. The notice filing is what makes it public and gives it priority against certain creditors. Requesting a hearing does not erase the filing.

IRC 6330(e) suspends levy actions that are the subject of a hearing. A lien-only hearing is not about a levy, so it does not create the same levy freeze that a levy CDP request does. What it does create is a forum, an independent decision-maker, and the right to go to court.

The collection statute is suspended for the period the hearing and any appeal are pending, under IRC 6330(e) as applied by IRC 6320(c).

Relief you can ask for

Withdrawal of the lien notice

IRC 6323(j) allows the IRS to withdraw a filed lien notice in specific situations, including when the filing was premature or not in accordance with procedures, when you have entered into an installment agreement (unless the agreement provides otherwise), when withdrawal will facilitate collection, or when withdrawal is in the best interests of the taxpayer and the government with the National Taxpayer Advocate's consent. A CDP hearing is a strong place to make the request because Appeals must address it in the determination.

Discharge and subordination

If you need to sell or refinance specific property, a certificate of discharge under IRC 6325(b) or subordination under IRC 6325(d) may be the real goal. Appeals can consider these as part of the hearing, though they also have their own application processes.

Collection alternatives

Installment agreements, offers in compromise, and currently not collectible status are all on the table. Resolving the underlying balance is often the most durable way to deal with the lien.

Procedural defects

Was the assessment valid? Was notice and demand sent? Was the lien filed in the right place? Was the Letter 3172 timely and properly addressed? Verification under IRC 6330(c)(1) covers these questions, and a defective process can support withdrawal.

Preparing the hearing request

A lien hearing is won or lost on specifics. When you file the request, state exactly what relief you want and why. A request that says only "I disagree with the lien" gives the settlement officer nothing to decide. Better examples:

  • "Request withdrawal under IRC 6323(j)(1)(B): the taxpayer will enter into an installment agreement, and the lien notice is impairing the taxpayer's ability to obtain the financing needed to make the payments."
  • "Request subordination under IRC 6325(d) to allow refinancing of the residence; the refinance will reduce the monthly mortgage and increase the amount available to pay the IRS."
  • "The lien was filed before notice and demand was issued for the 2022 assessment; request verification and withdrawal."

Then support it. Loan documents, an appraisal, a payoff statement, or a proposed installment agreement with financial statements all belong in the record before the conference.

Strategy: why request a lien hearing at all?

  • It preserves Tax Court review. A lien determination can be petitioned under IRC 6330(d)(1) as incorporated by IRC 6320(c).
  • It may be your only chance to raise liability. Under Treas. Reg. 301.6330-1, Q&A-E7, if you skip a lien CDP hearing, you are treated as having had a prior opportunity to dispute the liability for that period. A later levy hearing will not reopen it.
  • It gets an independent review of the filing decision. Revenue officers have discretion about when to file. Appeals can review that discretion.
  • It sets up a coordinated resolution. A determination that includes an installment agreement and a withdrawal decision resolves more than one problem at once.

That Q&A-E7 point deserves emphasis. Here's the part most people miss: ignoring the lien notice because "it is just a lien" can quietly forfeit your right to contest the tax later.

Missed the window?

For a lien notice, the equivalent hearing deadline is one year beginning the day after the end of the five-business-day period following the filing. The Collection Appeals Program also covers lien filings and denials of lien certificates, with fast timelines and no court review.
