Accounting & Tax Services in Detroit, MI

Detroit is America’s automotive capital and the epicenter of the EV transition. With Ford, GM, and Stellantis investing over $50 billion in electric vehicle and battery technology, the Metro Detroit economy is experiencing a manufacturing renaissance that extends across thousands of Tier 1 and Tier 2 suppliers. The city’s resurgent downtown, anchored by Rocket Companies and a growing tech startup scene in the Corktown and Midtown neighborhoods, has transformed Detroit into a hub for both industrial and digital innovation.

Detroit’s 2.4% city income tax (1.2% for non-resident employees) creates an additional compliance layer that many business owners overlook. Combined with Michigan’s flat 4.25% state income tax and the 6% Corporate Income Tax, Detroit businesses face three levels of income taxation that demand careful entity structuring. S-Corp owners operating within city limits should model whether the city tax savings from relocating to suburbs like Warren or Sterling Heights outweigh the benefits of a Detroit address.

SDO CPA works with Detroit business owners in automotive, technology, and healthcare to structure entities, claim R&D credits for EV component innovation, and manage the interplay between federal, state, and city tax obligations. Whether you’re an EV supplier along the I-94 corridor or a healthcare practice affiliated with Henry Ford Health, we provide monthly bookkeeping and fractional CFO services scaled to your growth stage.

Michigan Tax Planning Tip

Michigan’s flat 4.25% income tax applies to all pass-through entity income. Detroit businesses face an additional 2.4% city income tax (1.2% for non-resident employees). S-Corp owners in the Detroit metro should evaluate whether locating outside city limits reduces their total tax burden. Michigan’s flow-through entity tax election can also help bypass the federal SALT cap for owners with $200K+ in Michigan-source income.

Detroit is home to 35,000+ small businesses and a population of 633,218. From Automotive, Technology, Healthcare to professional services, Detroit business owners need CPAs who understand navigating Detroit’s 2.4% city income tax alongside state and federal obligations and can provide year-round tax planning — not just compliance.

Yes. Our fractional CFO services provide cash flow forecasting, budgeting, financial modeling, and strategic planning for Detroit businesses generating $500K+ in revenue that need financial leadership without a full-time hire.
