Employers hiring in Michigan are responsible for payroll tax withholding, unemployment insurance, workers’ compensation, and regular payroll reporting. They may also need to manage city income tax withholding where employees live or work in municipalities such as Detroit.

For international employers, Michigan payroll can be more complex than many other states because payroll obligations may include federal taxes, state taxes, and local city income taxes. Understanding where employees live and work is an important part of setting up payroll correctly and determining applicable withholding obligations.

Michigan income tax withholding

Michigan applies a flat individual income tax rate of 4.25% . Employers required to withhold federal income tax must register for Michigan withholding and apply the Michigan rate to taxable wages. Registration and filing are handled through the Michigan Department of Treasury.

Even one employee working in Michigan can create payroll withholding obligations for an out-of-state or international employer. Businesses also need to consider local income tax where employees live or work in cities that levy their own income tax, such as Detroit.

An Employer of Record (EOR) manages these payroll obligations on the employer’s behalf. This includes state payroll withholding, MI-W4 administration, payroll reporting, and year-end tax documentation, allowing employers to hire in Michigan without setting up their own payroll registrations.

Michigan city income tax: Detroit and other municipalities

Michigan is one of the few US states where employers may also need to withhold city income tax. According to the Michigan Department of Treasury, certain Michigan cities, levy their own income tax, so employers need to consider both where an employee lives and where they work.

Detroit has the highest city income tax rates, with a resident income tax rate of 2.4% and a non-resident income tax rate of 1.2%.Other cities, including Grand Rapids, Lansing, and Flint, also levy local income tax at different rates.

Remote work can also affect city tax withholding. For example, an employee who lives and works from home in Detroit may have different withholding obligations from an employee who lives outside Detroit but travels into the city for work.

For employers hiring across different Michigan locations, keeping track of state and local payroll taxes can quickly become complex. An Employer of Record (EOR) manages state and city payroll withholding as part of its payroll service, helping employers meet their payroll obligations without managing multiple local registrations.

Michigan unemployment insurance tax

Employers hiring in Michigan must register with the Michigan Unemployment Insurance Agency (UIA) and pay State Unemployment Insurance (SUI) tax. New employers generally start with a standard 2.70% unemployment insurance tax rate, while established employers receive an experience rate based on their claims history.

Michigan’s taxable wage base is 9,500 USD per employee. Once an employee’s earnings reach that amount for the year, no further SUI tax is payable for that employee. Employers must also report employee wages each quarter through the Michigan Web Account Manager (MiWAM) and respond to unemployment claims when employment ends.

For international employers, even one employee in Michigan can create unemployment insurance obligations. Many businesses choose an Employer of Record (EOR) to manage UIA registration, quarterly reporting, unemployment claims, and ongoing payroll administration without setting up their own employer registrations.

Michigan workers’ compensation: mandatory coverage

In Michigan, workers’ compensation coverage is mandatory for employers that meet the statutory coverage thresholds. Private employers must carry coverage if they regularly employ one or more workers for 35 or more hours per week for 13 weeks or longer or regularly employ three or more employees at one time.

Moreover, Michigan workers’ compensation can be obtained through a licensed insurer, assigned risk coverage or approved self-insurance. Operating without required coverage can create fines, uninsured injury liability and criminal exposure. Employers should confirm their workers’ compensation obligations before hiring employees in Michigan. Waiting until the workforce grows can leave the business without the required coverage.

Many companies choose an Employer of Record (EOR) because workers are covered under the EOR’s workers’ compensation policy. This means employers can hire in Michigan without arranging a separate workers’ compensation policy for their local workforce.

Michigan unemployment insurance

Michigan unemployment insurance responsibilities continue after payroll has been set up. When an employee resigns, is dismissed, or is laid off, employers must provide accurate information to the Michigan Unemployment Insurance Agency (UIA) to help determine the employee’s eligibility for unemployment benefits.

Employers in Michigan should also keep payroll and worker classification records up to date. The UIA can review these records during an audit, particularly where a business engages independent contractors.

Worker classification is especially important. Genuine independent contractors are generally not covered by Michigan unemployment insurance. If a worker is later found to have been misclassified, the employer may be required to pay unpaid unemployment insurance contributions and other related amounts.

Many employers use an Employer of Record (EOR) to manage unemployment insurance reporting, worker classification, and employment records as part of their ongoing payroll administration.
