For individual income tax (IIT), there are three methods you can use to update your address with Treasury: the IIT eService, the Customer Contact call center, or sending your request via mail.
Note: Treasury automatically updates past tax year addresses based on your current tax year filing. Therefore, you only need to update your address with Treasury if you moved between filings.
On the IIT eService, you can use either the Account Services portal or the Guest Services portal to update the active address on file with Treasury. After sending an address change electronically, you will receive a confirmation message. Generally, your address change will take 72 hours to process.
Note: MiLogin is a single sign-on application that supports many State of Michigan web platforms, including the IIT eService. To determine if you already have a MiLogin account, view the list of MiLogin supported web applications. If you do not have a MiLogin account, click Create a New Account instead of Sign in on the IIT eService.
Note: When you use Account Services through the IIT eService, you are only required to answer the verification questions one time for each tax year as opposed to every time you look up or send information through the Guest Services or Inquiries portals.
Note: Updating your information through the Customer Contact call center can take a variable amount of time to process. However, Customer Contact initiated change requests are generally completed within 30 days. A confirmation number for this change cannot be provided by the IIT Customer Contact team.
