CP575: confirmation of your employer identification number

A CP575 confirms your business's EIN. It's good news, not a bill: keep it, use the EIN everywhere, and keep your address and responsible party current.

What a CP575 means

A CP575 is the IRS confirming your employer identification number, the EIN your business uses on everything it sends the IRS and the Social Security Administration. source 1

The IRS page describes the CP575 as a digital notice you get through your business tax account. It says it can stand in for the original CP575 series of new-EIN notices and for Letter 147C, the letter that confirms an EIN already assigned. source 1

Nothing here is owed and nothing is wrong. We treat a CP575 like the birth record of the business: boring to read, a nuisance to replace, and asked for at the worst moment.

The date that counts

There is no response date: a CP575 asks for nothing back. The one timing rule the IRS page mentions is for later changes: a change of responsible party is reported on Form 8822-B within a set number of days, and the IRS page gives that window. source 1

Why people get one

  • You applied for an EIN for a new business, trust, estate or other entity.
  • You need written proof of an existing EIN, for a bank account or another business service, and pulled the confirmation from your business tax account.
  • You lost the original new-EIN notice, which the IRS says can't be duplicated or recreated.

First steps

  1. Check that the business name and EIN on the notice match what you applied for.
  2. Save the notice in your permanent records, the way the IRS page asks, and keep a few copies for anyone who asks to verify the EIN. source 1
  3. Use the EIN on every return, payment and form the business sends the IRS or the Social Security Administration. source 1
  4. If the address or the responsible party changes later, file Form 8822-B. source 1
  5. If anyone asks you to confirm or pay something about your EIN, check it in your business tax account at irs.gov, typed in yourself.

What not to do

  • Don't ask the IRS for a reprint of the original new-EIN notice. The IRS page says it can't be duplicated; the digital CP575 or Letter 147C serves instead. source 1
  • Don't pay anyone for an EIN confirmation through a link in an unexpected email or text. The IRS issues the EIN and the confirmation itself.
  • Don't let the responsible party on file go stale when owners or officers change.
  • Related LTR 147C The letter that confirms an EIN already assigned; the IRS page says the digital CP575 serves the same purpose.

Questions

Why would I need to confirm my EIN?

The IRS page gives opening a business bank account or getting other business services as the usual reasons. source 1

Can I get a copy of my original EIN notice?

No. The IRS says the original new-EIN notice can't be duplicated or recreated. The digital CP575 in your business tax account is the replacement. source 1

Is the digital CP575 the same as Letter 147C?

The IRS says it serves the same purpose, and that banks and other institutions accept it as written confirmation of an entity's EIN. source 1
