Accounting & Tax Services in Troy, MI

Troy is Oakland County’s premier corporate center, home to the North American headquarters of Stellantis, Inteva Products, and Kelly Services along the Big Beaver Road corridor and the Troy Tech Center District. With over 4,000 businesses, Troy’s economy is driven by automotive engineering R&D, technology companies, and financial service firms that serve the broader Metro Detroit market. The Top of Troy shopping district and the Columbia Center office complex attract corporate tenants including cybersecurity firms, software development companies, and management consultancies. Troy’s technology sector includes autonomous vehicle software companies, connected car platforms, and engineering simulation firms that often qualify for substantial R&D tax credits. The city has no local income tax, which combined with its proximity to I-75 and I-696 makes it attractive for businesses seeking Oakland County’s affluent customer base without Detroit’s additional tax layers. SDO CPA serves Troy technology firms, automotive engineering companies, and financial service providers with multi-state nexus analysis, R&D credit documentation, and entity structuring for pass-through owners. We analyze your financials monthly to track project-based revenue, manage contractor payments, and optimize Michigan’s flow-through entity tax election for qualifying business owners.

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.

Troy is home to 4,000+ small businesses and a population of 87,307. From Technology, Automotive Engineering, Finance to professional services, Troy business owners need CPAs who understand Multi-state nexus management for technology firms serving automotive OEMs across North America and can provide year-round tax planning — not just compliance.
