What this notice means
Employers, financial institutions or other third parties reported information that doesn't match your return. The difference might raise your tax, lower it or not change it at all.
It's not a bill, but a response is required. If you agree, the IRS figures any additional tax and sends you a CP2000. If you disagree and send support, the IRS may accept your return as filed.
Why you got it
- An employer, bank or other payer reported income or payments that aren't on your return.
- A payer reported a payment you left off your return because you believe it isn't taxable.
- Someone else used your name and Social Security number.
What to do now
- Read the whole notice and follow its instructions.
- If you agree, sign the response form and send it back by the date listed. If you filed jointly, both spouses need to sign.
- If you disagree, send the signed response form with a signed statement explaining why, documents that support you, any expenses tied to the income that may lower your tax, and an amended return or forms if the notice asks for them.
- If you include Form 1040-X, write 'CP2501' at the top.
- Reply by upload, which is the fastest way, or by fax or mail, as your notice explains. If you need more time, send an extension request using one of those reply options.
If you don't respond
After reviewing your reply, the IRS either accepts your return as filed or sends a CP2000 showing the proposed tax change. If you don't respond or ask for more time, additional tax could be assessed.
Questions people ask
Is a CP2501 a bill?
No. But you do need to respond by the date on the notice.
Do both spouses need to sign?
Yes. If you filed married filing jointly and you agree, the IRS needs both spouses' signatures on the response form.
What if the income isn't taxable?
Send a signed statement with your response form explaining why. The IRS mentions examples like state relief payments or income made nontaxable by the Infrastructure Investment and Jobs Act.
