What this notice usually means
The IRS uses different forms for different notices. Form 9465 asks for a monthly payment plan. Use it if you cannot pay the full amount owed. Form 12153 asks for a Collection Due Process hearing. Send it after a lien or levy notice, within 30 days. Form 12203 asks the IRS Office of Appeals to review an audit result. This applies when the amount is $25,000 or less for that tax period. Form 843 claims a refund. It can also ask the IRS to remove certain taxes, interest, penalties, or fees. File it within three years of filing the return, or two years of paying the tax, whichever is later. Each form answers a different notice. Each one has its own deadline. Match the form to what your own letter asks.
What to do now
- 1
Match your notice to the right form
Check whether your letter mentions a payment plan, a lien or levy, an audit appeal, or a refund and penalty claim. That tells you whether Form 9465, 12153, 12203, or 843 applies.
- 2
Check the deadline printed on your letter first
Form 12153 and Form 12203 both usually have a 30-day window from the date of the letter that offers the hearing or appeal. Your own letter has the real date.
- 3
File Form 12153 within 30 days to keep a full hearing
A late request can still get an Equivalent Hearing. You have up to one year to ask for it. But that later hearing will not pause a levy. It also will not keep your right to ask a court to review the result.
- 4
Use Form 843 within its own refund window
Generally file Form 843 within three years of filing the return or two years of paying the tax, whichever is later. Missing that window can end your right to the refund or abatement.
- 5
Send Form 9465 if you just need a payment plan
Form 9465 does not dispute the amount you owe. It only asks the IRS to let you pay it over time.
