What This Notice Means
You asked to be set up as the Designated Official (DO) for a business in the IRS Business Tax Account system. The CP311 gives you the Personal Identification Number (PIN) you need to finish that registration.
The Designated Official must be someone with authority to legally bind the business. Once registered, the DO can see the business's tax information, use the account's features, and manage other authorized users. That is real access. The IRS treats it that way.
What to Do
- Sign into Business Tax Account.
- Select the business entity you asked to register for.
- Enter the PIN from your notice.
Rules for the PIN
- It works one time only.
- It expires 30 days from the date of the notice.
- It is for your use only.
- It only works for DO access to the business you requested.
This PIN is not your e-file signature PIN, your Identity Protection PIN (IP PIN), or an ITIN. Don't mix them up.
If the PIN Expired or Doesn't Work
You'll need to request a new PIN. You must wait 14 days from your first request before asking for another one.
If the Notice Never Arrived
Check that the IRS has the business's current address. You can confirm or update it by phone or by mail. Once the address is right, request a new PIN. The same 14-day waiting period applies.
If You Didn't Ask for This
If nobody at the business requested DO access, treat it as possible unauthorized access or identity theft. Call the number on your notice and report it. If you can't finish registration and need help with an issue right away, use the regular ways of contacting the IRS, such as phone or correspondence.
If you received a CP311 you didn't request, or you need help with a business tax problem, call us at (813) 229-7100.
