Accounting & Tax Services in Sterling Heights, MI

Sterling Heights is Macomb County’s largest city and a cornerstone of Detroit’s automotive and defense manufacturing base. The Stellantis Sterling Heights Assembly Plant produces the Ram 1500, employing over 7,000 workers across multiple shifts and generating demand for hundreds of local suppliers, logistics providers, and service businesses. General Dynamics Land Systems maintains its headquarters here, designing and manufacturing military vehicles including the Stryker and Abrams platforms, creating a parallel defense manufacturing ecosystem.

The intersection of automotive and defense manufacturing gives Sterling Heights businesses unique accounting challenges: OEM cost transparency requirements, government contract compliance under the Federal Acquisition Regulation (FAR), tooling amortization schedules, and R&D credit documentation for both commercial and military product development. Michigan’s flat 4.25% income tax applies to all pass-through entity income, and the flow-through entity tax election offers S-Corp owners a mechanism to bypass the federal SALT deduction cap.

SDO CPA works with Sterling Heights business owners in automotive supply, defense contracting, and precision manufacturing to structure entities, navigate FAR compliance for government contracts, and maximize R&D credits across both commercial and defense product lines. Whether you’re a Tier 1 supplier to the Sterling Heights Assembly Plant or a defense subcontractor serving General Dynamics, 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. Sterling Heights manufacturers serving both commercial automotive and defense clients should track R&D activities separately, as defense-related development often qualifies for enhanced credits. The flow-through entity tax election can bypass the federal SALT cap, saving $3,000-$12,000 for S-Corp owners with $200K+ in Michigan-source income.

Sterling Heights is home to 7,500+ small businesses and a population of 134,346. From Automotive, Defense, Manufacturing to professional services, Sterling Heights business owners need CPAs who understand defense contract compliance and automotive supplier accounting and can provide year-round tax planning — not just compliance.
