Check my CP148B notice freeWhat the IRS says this notice is about
We changed your mailing address because we received an employment tax return or Form 8822-B, Change of Address or Responsible Party - Business, with a different address than the one we have on file. We send CPs 148 to both the employer’s former (148B) and new (148A) addresses to confirm the address change.
What you need to do
- If the address change is correct, you don’t need to do anything.
- If the address change is incorrect, please return the notice to us with a completed Form 8822-B, Change of Address or Responsible Party - Business PDF .
Your deadline
Answer by the date printed on your notice. If there is no date, answer as soon as you can, and call the number on the notice if you need more time.
What to check before you answer
You have 60 days to disagree
If you disagree with the change and ask in writing within 60 days of the notice date, the law requires the IRS to reverse it. If the IRS still disagrees, it must then use the regular process, which keeps your appeal rights.
Is this letter really from the IRS?
The IRS writes first by mail. A real letter shows a notice or letter number, your name and part of your tax ID number. The IRS does not ask for payment by gift card, crypto or wire transfer. If in doubt, sign in to your IRS online account, where many notices are listed.
