Michigan Workers' Compensation Payroll Guide

About The Michigan Payroll And Workers' Compensation Rules

Michigan payroll professionals play an important role in workers' compensation administration because payroll records provide important wage, hours, employment, classification, and payment information used to administer workers' compensation claims, calculate wage-loss benefits, support insurance reporting and audits, and document an employer's compliance responsibilities.

Understanding Michigan workers' compensation rules is especially important for payroll professionals who maintain employee records, calculate wages, process payroll after workplace injuries, respond to workers' compensation claims, or provide payroll information to an employer's insurance carrier, third-party administrator, self-insurance program, or the Michigan Workers' Disability Compensation Agency.

Michigan Workers' Compensation Compliance Overview

At A Glance

Michigan generally requires covered employers to provide workers' compensation protection, subject to statutory coverage thresholds and exemptions.

Private employers generally must provide coverage when they regularly employ 1 or more employees for 35 hours or more per week for 13 weeks or longer during the preceding 52 weeks, or when they regularly employ 3 or more employees at one time, including part-time employees.

Agricultural employers, household employers, and public employers are subject to additional Michigan coverage rules.

Most Michigan employers obtain workers' compensation insurance from private insurance companies, while some employers are authorized to self-insure or participate in an approved group fund.

Most workers are covered from the beginning of employment when the employer is subject to the Michigan Workers' Disability Compensation Act.

Employees should report workplace injuries to their employer immediately or as soon as possible.

Michigan has a seven-day waiting period for wage-loss benefits. If disability continues for two weeks or longer, compensation may be payable for the first seven days as well.

Michigan workers' compensation benefits can include reasonable and necessary medical treatment, wage-loss benefits, vocational rehabilitation, specific-loss benefits, and death benefits.

Michigan generally calculates wage-loss benefits using 80% of the employee's after-tax average weekly wage, subject to statutory minimums and maximums.

The 2026 Michigan maximum weekly workers' compensation rate is $1,201.00.

For injuries resulting in death, specific loss, or disability extending beyond seven consecutive days, employers generally must report the injury to the Workers' Disability Compensation Agency using Form WC-100. A fatal injury also requires Form WC-106.

During the first 28 days of medical treatment, the employer or insurance carrier generally has the right to choose the medical provider. After that period, the employee generally may choose a physician subject to Michigan requirements.

Michigan Workers' Compensation Employer Requirements

Michigan requires covered employers to provide a method of assuring payment of workers' compensation benefits to eligible employees who suffer compensable workplace injuries or illnesses. Most employers satisfy this requirement by purchasing workers' compensation insurance from a private insurance company. Some employers may qualify for self-insurance or participate in an approved group fund.

Michigan Workers' Compensation Insurance

Payroll departments should maintain current workers' compensation insurance information, including the insurance carrier, policy information, employer identification information, payroll classifications, claims administrator contact information, and other records needed to respond to claims and insurance audits.

Michigan's coverage requirements are based in part on the number of employees, hours worked, duration of employment, and type of employer. Payroll should coordinate with HR and management whenever employee counts, schedules, classifications, or business operations change.

Michigan Workers' Compensation Exemptions

Michigan law contains specific coverage rules and exclusions for certain individuals and categories of employment. A sole proprietor who is self-employed is generally not considered an employee of the sole proprietorship, while employees of the sole proprietorship may be covered when the employer meets Michigan's coverage requirements.

Employers should not assume that an individual is excluded merely because the person is an owner, officer, part-time employee, contractor, or family member. The applicable Michigan requirements should be reviewed before excluding an individual from workers' compensation coverage.

Michigan Workers' Compensation Coverage For Multistate Employers

Employers operating in multiple states should review Michigan workers' compensation requirements whenever employees perform services in Michigan. Payroll should maintain accurate records showing where employees perform services and should coordinate with HR and the employer's workers' compensation administrator when an employee travels, relocates, works remotely, or regularly performs services in multiple states.

Medical Treatment: Payroll generally does not administer medical treatment, but payroll should coordinate with HR and the claims administrator when medical restrictions affect work status, hours, wages, or return-to-work arrangements.

How Michigan Payroll And Workers' Compensation Work Together

Workers' compensation and payroll are closely connected. When an employee is injured at work, payroll may need to provide historical earnings, hours worked, employment information, wage changes, job classifications, and post-injury earnings.

Payroll may also become involved when an injured employee:

Misses work because of a workplace injury

Returns to work with medical restrictions

Works reduced hours

Performs modified or light-duty work

Receives wages after returning to work

Receives salary continuation or other employer-paid compensation

Experiences a change in compensation following an injury

Michigan payroll departments should maintain a documented procedure for responding to workers' compensation claims and producing historical payroll and hours-worked information. Payroll should coordinate with HR, management, the employee's supervisor, and the workers' compensation claims administrator when an injury changes an employee's work status or compensation.

Michigan Workers' Compensation Wage Information

Payroll records can be particularly important when a Michigan workers' compensation claim involves wage-loss benefits. Michigan generally bases wage-loss benefits on the employee's average weekly wage and the statutory formula applicable to the claim.

Payroll Wage Information

Payroll should maintain complete and accurate wage and employment records that can be used to determine the employee's applicable average weekly wage and benefit rate.

Maintain complete pre-injury wage records

Maintain hours-worked records

Track regular wages

Track overtime wages

Track bonuses and commissions

Track other compensation that may be relevant to the wage calculation

Document wage changes before the injury

Maintain employment and job-classification records

Provide accurate wage information to the carrier or claims administrator

Review wage information for accuracy before submission

Michigan Workers' Compensation Benefit Calculations

Average Weekly Wage: Michigan workers' compensation wage-loss benefits generally depend on the employee's average weekly wage and the applicable statutory calculation.

Wage-Loss Benefits: Michigan generally calculates wage-loss benefits at 80% of the employee's after-tax average weekly wage, subject to statutory limitations.

Maximum Weekly Benefit: The 2026 maximum weekly workers' compensation rate is $1,201.00.

Partial Disability: An employee who returns to work but has reduced wage-earning capacity may qualify for partial wage-loss benefits under Michigan law.

Specific Loss Benefits: Michigan provides benefits for qualifying specific losses identified under the Workers' Disability Compensation Act.

Death Benefits: Eligible dependents may receive workers' compensation benefits following a compensable work-related death.

Medical Benefits: Workers' compensation can provide reasonable and necessary medical treatment related to compensable workplace injuries and illnesses.

Vocational Rehabilitation: Qualifying injured workers may receive vocational rehabilitation services when they are unable to return to their previous employment.

Waiting Period: Michigan generally has a seven-day waiting period for wage-loss benefits. If disability continues for two weeks or longer, compensation may be payable for the first seven days as well.

Michigan Workers' Compensation Rates

Michigan workers' compensation insurance premiums are separate from employee workers' compensation benefit amounts. Michigan uses competitive workers' compensation insurance pricing, and premiums can vary based on the employer's classification, payroll, insurer, experience, loss history, and other applicable rating factors.

For 2026, Michigan's state average weekly wage is $1,333.88 and the maximum weekly workers' compensation rate is $1,201.00, which represents 90% of the state average weekly wage. The applicable benefit amount for an individual employee depends on the employee's wages, tax status, dependents, disability, and the applicable statutory formula.

Michigan Workers' Compensation Medical Care

Michigan workers' compensation can provide reasonable and necessary medical care for compensable workplace injuries and illnesses. Medical benefits should generally be provided from the date of injury.

During the first 28 days of medical treatment, the employer or insurance carrier generally has the right to choose the medical provider. After 28 days, the employee generally may choose a physician subject to applicable Michigan requirements.

Payroll generally does not administer medical treatment, but payroll information can become relevant when an employee's medical status affects work hours, wages, modified duty, or return-to-work arrangements.

Michigan Workers' Compensation And Modified Duty

An injured employee may return to work with medical restrictions when medically authorized. The employee may return to the regular position, a modified-duty position, or another position that complies with applicable restrictions.

Payroll should accurately record regular wages, reduced hours, modified-duty earnings, overtime, bonuses, and other compensation after an employee returns to work. Accurate post-injury earnings can be important when determining whether an employee continues to experience a loss of wage-earning capacity.

Document the employee's return-to-work date

Track work restrictions through the employer's HR and workers' compensation process

Track regular and modified-duty hours

Track post-injury wages

Track overtime and additional compensation

Document changes in pay or work schedule

Provide post-injury wage information when requested by the claims administrator

Update payroll records when the employee returns to regular duty

Additional Michigan Workers' Compensation Resources

Difficult Administrative Areas

Michigan workers' compensation administration can become complicated when payroll, human resources, management, medical providers, insurance carriers, third-party administrators, and the Michigan Workers' Disability Compensation Agency must coordinate information across different parts of an employee's claim.

Determining The Correct Wage Information: Payroll should maintain accurate historical wage and hours-worked information and provide the information requested by the insurance carrier or claims administrator.

Handling Employees With Multiple Jobs Or Pay Rates: Employees may work different positions, shifts, or jobs with different compensation arrangements. Payroll should maintain clear records showing the employee's wages, hours, duties, and applicable pay rates.

Tracking Modified-Duty Employees: Payroll should separately document regular wages, reduced hours, modified-duty earnings, overtime, and other compensation after an injured employee returns to work.

Coordinating Workers' Compensation And Paid Leave: Payroll should maintain clear records of vacation, sick leave, PTO, salary continuation, and other employer-paid compensation during a workers' compensation claim.

Handling Return-To-Work Changes: Payroll should promptly update records when an employee returns to work, changes hours, performs modified duties, changes compensation, or returns to regular duty.

Maintaining Accurate Injury And Employment Records: Payroll records should be consistent with HR, timekeeping, employment, and workers' compensation records.

Managing Subcontractor Coverage: Employers and contractors should maintain appropriate documentation concerning subcontractor status and workers' compensation coverage.

Multistate Employees: Employers with workers performing services in multiple states should maintain accurate work-location records and coordinate workers' compensation requirements with HR and the appropriate administrator.

Responding To Payroll Information Requests: Claims administrators may request detailed wage and hours-worked information. Payroll should establish a standardized process for gathering, reviewing, and transmitting accurate information.

Protecting Confidential Employee Information: Workers' compensation administration involves sensitive employee, wage, and medical information. Payroll should limit access to authorized personnel and use appropriate procedures when transmitting records.

Keeping Procedures And Rates Current: Michigan workers' compensation rules, benefit rates, insurance requirements, forms, and administrative procedures can change. Payroll and HR departments should periodically review their procedures and verify current Michigan requirements.

Common Errors

Michigan workers' compensation mistakes often occur when payroll, HR, safety, and management do not have a consistent process for identifying, reporting, and documenting workplace injuries.

Failing To Maintain Required Workers' Compensation Coverage: Employers should determine whether they meet Michigan's statutory coverage requirements and maintain appropriate workers' compensation protection.

Incorrectly Excluding Part-Time Workers: Part-time employees may be covered, including when an employer meets Michigan's three-or-more-employees coverage threshold.

Misclassifying Employees As Independent Contractors: A contract, Form 1099, or job title does not by itself determine whether a worker is an employee for workers' compensation purposes.

Failing To Report An Injury Promptly: Delaying an injury report can interfere with medical treatment, claim administration, investigation, and required reporting.

Using Incorrect Wage Or Hours Information: Incomplete or inaccurate payroll and timekeeping records can interfere with the calculation and administration of workers' compensation benefits.

Ignoring Post-Injury Earnings: Payroll should accurately record wages and hours after an employee returns to work, especially when the employee is working reduced hours or modified duties.

Failing To Track Benefit Payments: Payroll and HR should coordinate with the claims administrator when workers' compensation benefits begin, change, or stop.

Failing To Document Modified Duty: Employers should maintain accurate records of work restrictions, modified duties, hours, wages, and changes in work status.

Using Outdated Benefit Rates: Michigan publishes current weekly benefit tables and maximum rates. Payroll and claims personnel should verify current rates rather than relying on prior-year schedules.

Failing To Report Required Injuries: Employers should have procedures for identifying injuries requiring WC-100 or other applicable reports.
