CP05A notice — Handle it this month

The follow-up to a refund review: the IRS now wants specific documents — pay stubs, employer statements, withholding proof — before it releases your refund.

Handle it

What this letter is

The follow-up to a refund review: the IRS now wants specific documents — pay stubs, employer statements, withholding proof — before it releases your refund.

Why you got it: The CP05 cross-check didn't resolve on its own; a human (or a stricter filter) needs paper proof of income or withholding.

What it is not

Not an accusation; it's a document request with a deadline. The risk is real though: no documents can mean an adjusted or denied refund.

Your first move: Send exactly what's listed, copies only, by the date on the notice. Employer letters on letterhead fix most withholding mismatches.

Your deadline, counted

Every clock runs from this date — not from the day the letter reached you.

Your options, in the order most people should try them

1. Send the listed documents

Copies, complete, with a cover note naming the notice and year.

2. Employer won't cooperate?

Pay stubs + a written statement of what you requested; the IRS has a path for uncooperative employers (Form 4852 territory).

Your rights on this letter

  • More time on request; substitute documents where the letter allows.
  • Any later adjustment comes with its own notice and dispute rights.

How to respond

Address/fax on the notice; keep copies and proof of sending.

Scam check

Documents go to the address on the paper notice — never to an email address a stranger gives you.

If you ignore it

The refund can be reduced or denied based on the records the IRS has — and then you're appealing instead of proving.
