How do I handle city income tax for Detroit businesses?
Detroit imposes a city income tax that affects most businesses operating in the city. Your main obligation is withholding tax from employee wages, though some businesses also owe tax on profits.
For employee withholding, the rate depends on where your employees live. Detroit residents pay 2.4% of their wages. Non-residents working in Detroit pay 1.2%. You withhold this from each paycheck alongside federal and state taxes. Get the residency status wrong and either your employees owe money at tax time or you’re not withholding enough.
Register with the City of Detroit Income Tax Division before you start withholding. This is separate from your Michigan withholding account. You need a Detroit employer account number to file returns and make payments.
File quarterly withholding returns reporting total wages and taxes withheld. The deadlines are April 30, July 31, October 31, and January 31. Make deposits according to the schedule Detroit assigns based on your withholding volume. Higher volume means more frequent deposits.
At year end, submit W-2 information to the city showing Detroit wages and withholding for each employee. The deadline is February 28. Missing this creates problems for employees trying to file their own Detroit returns and can trigger notices from the city.
Most payroll processing systems can handle Detroit withholding if configured correctly. QuickBooks, Gusto, and similar software calculate local taxes when set up properly. Verify that your system is using the right rate based on each employee’s residency status.
Corporations operating in Detroit may also owe a separate business income tax on profits at 2%. Partnerships and S-corps typically pass income through to owners. If you’re unsure whether your entity owes business-level tax beyond withholding, check with a tax professional.
Common mistakes include not registering at all, especially for businesses based outside Detroit with employees working there. Others use the resident rate when they should use the non-resident rate, or they miss quarterly deadlines and let penalties accumulate.
If you’re behind on Detroit filings, catch up as soon as possible. File the returns you missed and pay what you owe. Penalties and interest add up, but ignoring the problem makes it worse. Many Macomb, MI bookkeepers have helped Metro Detroit businesses get compliant and stay that way.
