Accounting & Tax Services in Dearborn, MI

Dearborn is the global headquarters of Ford Motor Company and home to the iconic Rouge Complex, one of the largest integrated manufacturing facilities in the world. Ford’s $950 million investment in the Rouge Electric Vehicle Center for the F-150 Lightning has transformed the local economy, drawing EV component suppliers, battery technology firms, and advanced engineering consultancies to the Michigan Avenue and Oakwood Boulevard corridors. The University of Michigan-Dearborn campus produces engineering graduates who feed directly into the automotive supply chain, and the city’s Fairlane Town Center district hosts professional service firms that support Ford’s vendor ecosystem. Dearborn’s diverse business community along Warren Avenue and Ford Road includes restaurants, retail operators, and healthcare providers serving a population of nearly 108,000. Unlike neighboring Detroit, Dearborn does not impose a city income tax, giving businesses a tax advantage while maintaining proximity to Detroit’s workforce and infrastructure. SDO CPA serves Dearborn automotive suppliers, engineering firms, and small businesses with cost accounting for manufacturing operations, R&D tax credit documentation for EV innovation, and entity structuring that takes advantage of Michigan’s flow-through entity tax election for pass-through owners earning $200K+ in state-source income.

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.

Dearborn is home to 4,900+ small businesses and a population of 107,846. From Automotive, Manufacturing, Engineering to professional services, Dearborn business owners need CPAs who understand Complex automotive supplier cost accounting and R&D credit documentation for EV component development and can provide year-round tax planning — not just compliance.
