What Happens at an IRS Collection Due Process Hearing

The Two Notices That Trigger a CDP Hearing

Collection Due Process rights do not attach to every IRS notice. They attach to two specific ones: a Notice of Federal Tax Lien filing, which arrives as Letter 3172, and a Final Notice of Intent to Levy, which arrives as Letter 1058 or LT11. Both give the taxpayer 30 days to request a hearing before Appeals, according to the IRS's own CDP FAQ page. An earlier balance-due notice, such as a CP504, does not carry this right on its own, even though it is often the notice that first tells a taxpayer the account has moved into active collection.

The request is filed on Form 12153, Request for a Collection Due Process or Equivalent Hearing. The IRS instructs taxpayers to state their issues in as much detail as possible and to include a current financial statement, Form 433-A for an individual or Form 433-F for a simplified version, so Appeals has something concrete to evaluate rather than a bare objection. A vague request, one that just says the taxpayer disagrees, moves slower and gives Appeals less to work with.

Filing on Time Stops Collection

The practical value of a timely CDP request is that it suspends enforced collection, meaning the IRS generally cannot levy a bank account or garnish wages, while the hearing is pending. That is the detail most taxpayers do not know when a lien notice first arrives: the 30-day clock is not just a deadline to beat, it is the mechanism that buys time to actually address the underlying balance through an installment agreement, an offer in compromise, or a currently-not-collectible determination, without the account being levied in the meantime.

Miss the 30 days and the request still has a path, just a weaker one. Form 12153 can be filed within one year of the notice as a request for an Equivalent Hearing instead. Appeals will still review the case on largely the same terms, but an Equivalent Hearing does not suspend collection while it is pending, and its outcome cannot be appealed to the U.S. Tax Court. That second point matters more than it sounds like it should, because judicial review is the backstop that keeps Appeals honest, and it is only available to a taxpayer who filed on time.

What Appeals Can and Cannot Consider

A CDP hearing is not a forum to relitigate whether the tax is owed, except in narrow circumstances, generally when the taxpayer never received a prior opportunity to dispute the liability. Where the underlying liability is off the table, Appeals instead considers collection alternatives: an installment agreement, an offer in compromise, currently-not-collectible status, or whether the proposed levy is more intrusive than necessary given the taxpayer's circumstances. Per the IRS's Internal Revenue Manual section on collection appeal rights, Appeals also weighs whether the collection action balances the government's need for efficient collection against the legitimate concern that it be no more intrusive than necessary.

A taxpayer who genuinely disputes the liability itself, not just the collection method, has other avenues: paying in full and filing a refund claim, requesting audit reconsideration with new evidence, or filing an offer in compromise on doubt as to liability grounds. Bringing the right issue to the right forum is most of what makes a CDP request effective rather than a formality that gets a routine denial.

The Notice of Determination and the Tax Court Window

When Appeals finishes its review, it issues a Notice of Determination. A taxpayer who disagrees with that outcome has 30 days from the date of the notice to file a petition with the United States Tax Court, under Internal Revenue Code section 6330(d). This deadline is treated strictly. If the petition is not timely received, the case is returned to Collection and the determination stands. There is no equivalent judicial review available after an Equivalent Hearing, which is the main practical difference between filing on day 20 and filing on day 45.

Most CDP cases resolve at the Appeals level without ever reaching Tax Court, because the point of the hearing is usually to negotiate a collection alternative rather than to litigate. The firm treats the Tax Court option as leverage that a timely filing preserves, not a step most clients actually need to take.

Where This Comes Up Locally

A Hamilton County taxpayer, whether in Chattanooga proper or in a surrounding community like East Ridge, who receives a federal tax lien notice is also dealing with a document recorded at the county level once the IRS files it. That recorded lien can affect credit and property transactions well beyond the CDP hearing itself, which is one more reason the 30-day window matters: a timely-filed request does not remove a lien that has already been recorded, but it does open the door to negotiating a resolution that can lead to a lien withdrawal or release once the underlying issue is addressed. See the firm's page on tax lien relief for how that process works separately from the CDP hearing itself. A levy notice raises a more immediate concern, since a bank levy or wage garnishment can move quickly once the 30-day window closes without a request on file.
