Michigan rules for construction & trades

State income tax (2026): Michigan has a flat 4.25% state income tax for 2026. Treasury confirmed on April 15, 2026 that the rate stays at 4.25% for 2026 because the conditions for the automatic rate-cut trigger were not met. Twenty-four Michigan cities also levy income taxes. For example, Detroit charges 2.4% for residents and 1.2% for nonresidents.
State estimated tax: You must make estimated payments if you expect to owe more than $500 with your 2026 MI-1040, unless withholding covers 90% of 2026 tax, 100% of 2025 tax, or 110% of 2025 tax if 2025 AGI was over $150,000. Same dates as federal (April 15, June 15, Sept. 15, 2026, and Jan. 15, 2027). You can skip the fourth voucher by filing your 2026 return by Feb. 1, 2027. Form MI-1040ES.
IRS 20-factor test for unemployment and workers' comp (MCL 421.42 and 418.161): Since Jan. 1, 2013, Michigan has used the IRS 20-factor common-law test (Rev. Rul. 87-41) to decide whether a worker is an employee for unemployment insurance and workers' compensation. Anyone whose employer must withhold federal income tax is presumed to be an employee.

Federal rules for 2026

W-2 or 1099 changes everything

On a W-2 your employer withholds tax and may offer a retirement plan. As a 1099 subcontractor you pay self-employment tax and quarterly estimates, but you can deduct tools, materials and job-site driving.

Tools and equipment

Tools, equipment, safety gear and work vehicles used for business are deductible; larger purchases can often be written off in the year you buy them.

Overtime deduction for W-2 workers

Non-exempt W-2 workers can deduct the overtime premium they are paid, up to $12,500 a year ($25,000 joint) from 2025 through 2028, subject to an income phase-out.

Quarterly estimated taxes

No one withholds tax from self-employment income, so you generally pay estimates four times a year if you expect to owe $1,000 or more. For 2026 income the federal dates are April 15, June 15 and September 15, 2026, and January 15, 2027. Paying 100% of last year's tax (110% if your AGI was over $150,000) in four equal installments avoids the underpayment penalty.

A worked example
