When does economic nexus trigger in Michigan?

Michigan economic nexus triggers when a remote seller exceeds $100,000 in revenue or 200 transactions from Michigan customers within a calendar year. Once triggered, the seller must register with the Michigan Department of Revenue and begin collecting and remitting sales tax.

How long do I have to register after crossing nexus in Michigan?
