CP2000 showing a refund or no change: should you reply?

By Tax Letter Desk Updated November 4, 2026

Short answer

The mismatch on a CP2000 can raise your tax, lower it or leave it unchanged. A reply may still be required.

If the notice shows a refund and asks for your signature, sign and return the form.

Pub 5181 says to expect the refund in 6 to 8 weeks, if you owe no other debts the IRS must collect.
