Michigan Insurance Data Security Law

The Michigan Insurance Data Security Law added Chapter 5A, MCL 500.550 to 500.565, to the Insurance Code of 1956. Effective January 20, 2021, the law established new data security requirements for licensed insurers and producers. Please see this FAQ for answers to frequently asked questions.

Notification Requirements and Fines

In the state of Michigan, businesses are required to investigate when a data breach compromises personal information. Businesses must notify affected Michigan residents as soon as possible by mail, telephone, or electronic means. When the security breach reaches more than 500,000 people, or the cost of notification exceeds $250,000, public service announcements can be used in lieu of individual notification. When breaches affect more than 1,000 people, consumer-reporting agencies must be notified, too. Failure to do so can result in fines up to $750,000.
