Getting a Final Notice of Intent to Levy or a Notice of Federal Tax Lien filing from the IRS can feel like the clock starts ticking all at once. In many cases, that instinct is right. A Collection Due Process (CDP) hearing is one of the main ways taxpayers ask the IRS Independent Office of Appeals to review a proposed levy or lien filing before collection moves forward, but the deadline is short and the rules are technical. The IRS generally gives 30 days to request a timely CDP hearing, and missing that window can change the remedies available, including access to Tax Court review in many situations. IRS Publication 594, IRS Publication 1660, and 26 U.S.C. § 6330
In this post, you’ll learn how to request a CDP hearing, where the deadline comes from, what to include, where to send it, and what may happen if the 30-day period has already passed. If you want a broader overview of how these hearings fit into IRS collection defense, this guide on protecting your rights in the IRS collection process adds useful background.

A timely CDP request can do more than preserve a conversation with Appeals. In general terms, a timely request may also pause certain collection activity and preserve the taxpayer’s ability to seek judicial review after Appeals issues its determination. By contrast, if the request arrives late, the IRS may treat it as a request for an Equivalent Hearing instead. Equivalent Hearings can still be useful, but they usually do not carry the same collection suspension rules or the same path to Tax Court review. IRS Form 12153 Instructions, Taxpayer Advocate Service on Form 12153, 26 U.S.C. § 6330
That difference is why timing often becomes the first and most important issue. Before arguing about liability, payment options, hardship, or levy alternatives, many taxpayers are trying to preserve the hearing itself.
Not every IRS collection letter gives CDP rights. The notices that commonly trigger them include:
The IRS explains that CDP rights generally arise when it files a notice of federal tax lien or before it makes the first levy for a particular tax liability. IRS CDP FAQs, Taxpayer Advocate Service, 26 U.S.C. § 6330
A practical point: many IRS letters look similar. Some discuss balances due, some discuss installment agreements, and some warn about future enforcement without yet creating CDP rights. The specific notice number and wording on the letter often control the next step. If the notice says you have a right to a hearing under IRC 6320 or 6330, that is the signal to focus on Form 12153 and the deadline on the page.
For a levy notice, the IRS states that a CDP request generally must be filed on or before 30 days after the date of the notice. For a lien notice, the deadline generally runs 30 days after the end of the 5-business-day period following the filing of the Notice of Federal Tax Lien. If that timely period is missed, the taxpayer may still request an Equivalent Hearing within a longer period, generally one year from the relevant notice date for levy notices, or one year plus five business days from the lien filing date for lien notices.

This is where many deadline problems start. Some taxpayers count from the day they opened the letter. Others count from the mailing date on the envelope. In many cases, the IRS uses the date shown on the notice itself. That means a letter sitting unopened for a week can quietly reduce the time available.
Because lien and levy notices calculate differently, people often misread one as the other. That is one reason taxpayers often look for guidance on common errors that can wipe out review rights in a CDP case before submitting anything.

The IRS encourages taxpayers to request a hearing on Form 12153, Request for a Collection Due Process or Equivalent Hearing. The form is usually enclosed with the CDP notice. The IRS also accepts another written request if it contains the same information and is signed by the taxpayer or an authorized representative. IRS Form 12153, IRS Internal Revenue Manual 5.19.8
A valid written request generally includes:
