Freelancing in Michigan comes with a level of independence that many workers find rewarding, but that freedom also carries tax responsibilities that can catch you off guard. Knowing what your potential federal and state tax obligations are can go a long way toward helping you avoid any issues in the future.
The federal self-employment tax
If you are earning $400 or more in net self-employment income for the entire year, the Internal Revenue Service (IRS) requires you to pay self-employment tax. The combined rate of 15.3% breaks down into the following:
- 12.4% for Social Security applies only to the first $184,500 in net earnings for the 2026 tax year
- 2.9% for Medicare applies to all net earnings with no cap
There is also an additional surtax on earnings above $200,000 for single filers or $250,000 for married couples filing jointly.
Michigan’s flat income tax on freelance earnings
The state does not impose a separate self-employment tax. Instead, it applies a flat individual income tax rate that stays the same regardless of how much you earn, which makes it relatively straightforward to estimate what you might owe.
For the 2026 tax year, the individual income tax rate remains at 4.25%. Michigan bases its calculation on your federal adjusted gross income, so the deductions you claim at the federal level can also influence your state tax liability.
Certain cities also levy their own local income taxes on top of the state rate. Detroit, for example, charges residents an additional 2.4%, while cities like Grand Rapids and Saginaw impose their own local rates as well.
Deductions that could shrink your tax bill
One of the advantages of freelancing is the range of deductions available to self-employed workers. The following could lower both your federal and state tax obligations:
- Home office expenses, if you use a dedicated space in your home exclusively and regularly for business purposes
- Half of your self-employment tax, which the IRS allows as an adjustment to your gross income
- Business-related supplies, software, equipment and mileage you use for work
Tracking expenses consistently throughout the year makes tax season smoother and helps you catch deductions you might otherwise miss.
A tax planning strategy going forward
Every freelancer’s tax situation looks a little different depending on income level, business structure and filing status. What works for one independent contractor may not apply to another, which is why a one-size-fits-all approach rarely covers all the bases.
An attorney can review your specific circumstances and help identify deductions or credits you may not realize you qualify for. They can also assist with setting up quarterly estimated tax payments, which helps you avoid underpayment penalties and keeps your cash flow more predictable throughout the year.
