IRS Notice CP575: What It Means and What to Do

Why did I get a CP575?

Common reasons include:

• You applied for and were assigned a new EIN (original CP575A-J series)
• You downloaded a digital CP575 from Business Tax Account to confirm your EIN
• A bank or other business needed written confirmation of your EIN

What should I do?

1. Check that the business name and EIN on the notice are correct.
2. Keep the notice in your permanent records.
3. Use your EIN on all items you send to the IRS and the Social Security Administration for your business.
4. Make several copies, since the notice can be used when someone asks you to verify your EIN, for example when opening a business bank account.
5. If you need proof of your EIN later, download a digital CP575 in Business Tax Account (if eligible), or call the IRS Business & Specialty Tax Line and ask for Letter 147C, EIN Previously Assigned.

What documents do I need?

• The CP575 notice (keep the original)
• Copies of the notice for banks and other institutions
• Your business formation documents, stored with the notice
• Access to your IRS Business Tax Account, if you're eligible

What should I avoid?

• Don't throw the notice away; the IRS says the original CP575A-J can't be duplicated or recreated.
• Don't apply for a new EIN just because you lost the notice; use the IRS options to confirm your existing EIN.
• Don't use the EIN inconsistently; use it on all business items sent to the IRS and SSA.

What if I disagree with a CP575?

The IRS page doesn't describe a dispute process; the notice only confirms your EIN. If something on it looks wrong, contact the IRS using the number on your notice or the Business & Specialty Tax Line listed on the IRS EIN page.

What happens if I ignore a CP575?

No action is required. If the notice is lost, the original CP575A-J can't be reissued, but the IRS offers a digital CP575 in Business Tax Account, Letter 147C, or an entity transcript to confirm your EIN.

What else should I know about CP575?

Many owners treat the CP575 as a one-time letter, but it's the document banks usually ask for as proof of your EIN, and the IRS says the original CP575A-J notice can't be duplicated or recreated. The IRS now offers a digital CP575, Employer Identification Number Verification Notice, available only through Business Tax Account. It says the digital version is accepted by banks and other institutions and can substitute for both the original notice and Letter 147C, EIN Previously Assigned. If you can't use Business Tax Account, the IRS EIN page says you can still call the Business & Specialty Tax Line to ask for Letter 147C, or request an entity transcript.
