Michigan SB0583 amends tax administration to allow electronic notices and requires confidentiality of taxpayer information.

Michigan SB0583 amends the Michigan business tax act to allow taxpayers to consent to receive notices electronically. It also mandates that certain information, such as apportioned business income tax base and total final liability, be disclosed only under specific conditions and to authorized entities. The bill emphasizes confidentiality and restricts the disclosure of taxpayer information to authorized personnel and entities, with penalties for violations. It also allows for the revocation of electronic notice consent by taxpayers.
