Data Breach Laws in Michigan: 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.
