Sample IRS response letter package
Here is a complete, real-format response package for a typical scenario, every document you'd receive for $39, annotated so you can see why each piece matters.
A taxpayer receives a CP2000 proposing $4,618 in additional tax: the IRS matched a 1099-B from a brokerage and assumed a cost basis of zero on $12,400 of stock sales. The correct position: partial disagreement, accept a small forgotten 1099-INT, contest the stock proposal with the brokerage statement. (All names and figures below are illustrative.)
The response letter, IRS-formatted, ready to sign
Not a generic template: a letter built from your notice and your answers. It references the notice number, tax year and each contested item precisely, the format the IRS Automated Underreporter unit processes fastest.
- States the position (partial agreement) in the first paragraph, no ambiguity
- Addresses each item separately with the matching evidence named
- Requests penalty removal with a reasonable-cause basis
- You review, sign, and stay in full control of what's sent
AUR Correspondence, P.O. Box 00000, City, ST
Response to Notice CP2000 dated June 28, 2026
To whom it may concern:
I am responding to the above-referenced notice within the stated deadline. I partially disagree with the proposed changes, as detailed below.
Item 1, Interest income, Bank Name ($142): I agree with this item, which was omitted in error.
Item 2, Securities proceeds, Brokerage ($12,400): I disagree. The proposal assumes a cost basis of $0. As shown on the enclosed Form 1099-B and account statement, the aggregate cost basis was $11,930, resulting in a net gain of $470, not $12,400…
Proposed accuracy-related penalty: I respectfully request removal for reasonable cause, as…
The evidence checklist, matched to each item
The most common reason IRS responses fail isn't the letter, it's missing or mismatched documentation. Your checklist maps each contested item to the exact proof that supports it, with tips on what the IRS looks for.
- One evidence line per contested item, nothing generic
- Copies only, never originals (the checklist reminds you)
- Each attachment labeled to the item it supports
Exact sending instructions, no guessing
The IRS has dozens of addresses and several response channels; sending to the wrong one costs weeks. Your instructions give the exact destination for yournotice, and when the IRS Document Upload Tool is available for it, we tell you (it's the fastest channel).
- The specific AUR address or fax from your notice, verified
- Certified-mail guidance so you can prove the date
- What to keep: a full copy of everything you send
Deadline reminders & what happens next
The package doesn't stop at the mailbox. You get email reminders before your deadline, and a plain-English preview of the IRS's possible replies, no-change letter, reduced recomputation, or a request for more information, so nothing that arrives next surprises you.
- Reminder emails at D-7 and D-2 before your deadline
- Typical IRS response time for your notice (60-90 days for a CP2000)
- What each possible IRS reply means, and your next move for each
Your notice deserves the same treatment.
