CP2000 response letter sample: when part of the proposed change is wrong

When this letter fits

A CP2000 proposes changes to your return because income or payment information that others reported to the IRS does not match what is on the return. The IRS says it is not a bill, and the change may increase, decrease or leave your tax unchanged. This sample suits a common middle case: some of the listed items are right, some are duplicates or belong to someone else, and you want to explain item by item.

Picture a self-employed designer who receives a CP2000 listing three payers. One payer's 1099 was reported on the return, a second was combined into a single line, and the third form carries her Social Security number but is for a different person's work. The letter walks through each one in order.

Read your notice before you adapt anything

Your notice tells you how to reply: the response form, the IRS document upload tool, a fax number or the mailing address at the top left. It also gives the date by which to reply; the IRS gives no standard day count, so write nothing from memory and use the date on your notice. Publication 5181 describes the choices as agree or disagree, so complete and sign the response form to match what you decided and attach this letter as your explanation.

If you need more time, the IRS says you can ask by mail, fax or the toll-free number on the notice. If you neither respond nor ask, additional tax could be assessed and interest keeps accruing, and the IRS may later send a notice of deficiency with a 90-day period to petition the Tax Court that cannot be extended.

The sample letter

Replace every bracketed placeholder with details from your own notice and records. Delete lines that do not apply.

How to adapt it

Keep each item in the order the notice lists it, and use the notice's own wording for the payer name and amount. State what you accept without argument, because a clear concession on one line makes your explanation of the other lines easier to follow.

Describe documents rather than characterizing people. "The enclosed bank statement shows the deposit was a reimbursement" is better than an accusation. If you need a record you do not have, an IRS wage and income transcript can show what payers reported.

What to attach

Enclose copies, never originals, and label each one with the item number it supports.

• The signed CP2000 response form
• A copy of the first page of the notice
• The return pages where the item was reported
• The payer's corrected form, if one was issued
• Bank or ledger records tying deposits to the item
• A short written note for each duplicated or misattributed form

Sending it

Mail by a method with a receipt and keep a complete copy. IRS Audit Defense Pro is software that helps you organize your facts and draft a response letter you review and send yourself. It is not a law firm, CPA or enrolled agent, and it gives no legal or tax advice.
