You missed an IRS response date: what to do next

Last updated · Situations and problems
Short answer

Contact the IRS using the number or address on your notice as soon as you notice the date passed. What is still possible depends on the notice type: some responses can simply be sent late, a late hearing request may still get a limited hearing, and a Tax Court petition deadline cannot be extended.

Start by identifying which notice you have

Missing a date is easy to do, especially when a notice arrives during a move, an illness or a busy season. Before you decide how worried to be, find the notice number in the upper right corner of the first page and note what kind of deadline it carried. The consequences of a missed date vary a lot.

A response date on a notice such as a CP2000 is not a Tax Court deadline. The IRS page says that if you neither respond nor request more time, the IRS may send another notice and a bill, and in some cases a notice of deficiency may follow. Replying late is generally still better than not replying, and contacting the IRS by the number on the notice is the usual way to ask for more time or to send your response.

Deadlines that are firm and deadlines that are not

The firmest deadline is the one on a notice of deficiency, such as a CP3219A. It gives you 90 days to petition the U.S. Tax Court (150 days if the notice is addressed outside the United States), and the last day to file is printed on the notice. Replying to the IRS does not extend that date, and the Tax Court cannot consider a late petition. If this is your notice and the date is close or recent, treat it as the priority and read the Tax Court's own filing instructions.

Other deadlines have more give. The IRS generally allows about 30 days to request a Collection Due Process hearing after a lien or levy notice, but a late request can still get what the IRS calls an equivalent hearing. Penalty relief requests and penalty appeals work on their own timelines, described below.

  • Notice of deficiency: firm. Date printed on the notice. No extension.
  • CP2000-type response date: contact the IRS and ask for more time or send your response.
  • Collection Due Process request: about 30 days from the notice date; a later request may be heard as an equivalent hearing.
  • Penalty appeal after a denial letter: generally about 30 days from the date of the letter; check your letter.

If the date for a collection hearing passed

Say you received a final notice of intent to levy and put it in a drawer. If you are still within the IRS window for late requests (your notice and the CDP FAQs page give the length), you can ask for an equivalent hearing using Form 12153. The IRS explains that an equivalent hearing differs from a timely one: the timing protections that a timely request provides do not carry over in the same way, and the result cannot be taken to court. For a lien, the equivalent-hearing window is measured from the lien filing, and the IRS Appeals pages give the specifics.

Because levy action can move quickly once a deadline lapses, call the number on the notice before you finish the paperwork, and ask what collection alternatives you can still use, such as a payment plan.

Penalties for being late

If a missed date led to a penalty, the IRS may remove or reduce some penalties when you acted with reasonable cause and in good faith. It decides this case by case. The IRS page lists examples such as a fire or disaster, an inability to get records, or a serious illness or death in the family. It says that relying on a tax professional, not knowing the rule, or lacking funds alone generally do not qualify.

The usual first step is to call the number on your notice with the notice and your facts in front of you. If that does not resolve it, you can ask in writing, often on Form 843. If the IRS denies your request, the denial letter explains how to appeal to the IRS Independent Office of Appeals, generally within about 30 days of the letter.

What not to do

Avoid waiting for the IRS to follow up. Each additional notice tends to narrow your choices, and interest keeps accruing on any unpaid amount in the meantime.

Avoid sending a response without a clear explanation of why it is late. A short, factual sentence is enough, such as the dates you were hospitalized or the date you moved. Keep copies of everything you send and note how and when you sent it.

How a written response fits

A late response works best when it is organized: the notice number, what you are responding to, why it is late, and the documents that support your position. IRS Audit Defense Pro is software that helps you organize your facts and draft a letter you review and send yourself. It does not give legal or tax advice and cannot promise how the IRS will respond. If you are near a Tax Court deadline, consider speaking with a qualified tax professional or a Low Income Taxpayer Clinic quickly.

Frequently asked questions

Can I still respond to a CP2000 after the date on the notice?

Often you can, but the IRS may already have sent another notice. Contact the IRS using the information on your notice, ask whether your response can still be considered, and send it with supporting documents.

What if I missed the Tax Court deadline on a notice of deficiency?

The Tax Court cannot consider a late petition, and the IRS can then assess the tax. Contact the IRS about payment options and speak with a qualified professional about what remains available.

Is there any way to ask for more time before a deadline?

For many notices you can request more time by the number, fax or mail option on the notice before the date passes. That does not apply to the Tax Court petition deadline, which cannot be extended.

Will I automatically get penalties for responding late?

Not automatically for the response itself, but unpaid tax keeps accruing interest and penalties. If you have a good reason for lateness, the IRS may consider reasonable cause relief for certain penalties.
