Sick leave laws in Michigan are set to undergo significant changes starting Feb. 21, 2025. The reinstatement of the Earned Sick Time Act (ESTA) by the Michigan Supreme Court will replace the current Michigan Paid Medical Leave Act (PMLA), which has been in effect since 2019.
Mosey is here to help Michigan employers understand the upcoming changes, their implications, and how you can manage state compliance with changing leave laws.
Business tax planning can be complicated. It’s particularly involved for employers with multi-state payroll, who need to figure out withholding obligations in every state where they employ workers.
If you do business or employ workers in one of the 15 states that allow local jurisdictions to impose income taxes, you might also need to withhold and remit local income taxes where your employees live, work, or both.
Most businesses are managing modern compliance requirements with tools built for a different era.
Ten years ago, spreadsheets and email reminders could handle multistate compliance. Multistate compliance mistakes were rare because state payroll was simpler. Employees worked from offices. State compliance requirements changed slowly. And companies expanded more deliberately, usually one state at a time.
But that world no longer exists.
Today’s compliance management landscape is constantly shifting. Remote employees scattered across state lines overnight. Regulations update continuously. And what used to be manageable for employers has become a tangled knot of requirements that outdated tools simply can’t manage.
