Determination Letter Applications – Provide Your Correct Address

The Employee Plans determination letter function mails thousands of notices and letters every year but receives hundreds of them back as “undeliverable” because of incorrect or missing address information on the application or power of attorney forms.

What can you do to ensure that you receive your acknowledgement notice or determination letter?

Before submitting your application, make sure your address is complete and correct on both the determination letter application and power of attorney (if applicable) forms:

  • Include the suite, room, floor, or other unit number after the street address. (This is the most common error we see.)
  • If the Post Office does not deliver mail to the street address and the plan sponsor has a P.O. Box, you should use the P.O. Box number in the address instead of the street address.

If you realize after filing your application that the mailing information is incorrect, incomplete or an old address, you should notify us at the address below so that we can change your address. Please include:

  • your correct mailing address
  • plan sponsor’s name
  • plan sponsor's EIN
  • plan name
  • plan number
  • date the application was filed

Do not send a copy of your application.

If your representative’s address has changed, you aren’t required to complete a new power of attorney form. Your representative can send a signed statement identifying the correct information.
