Accounting & Tax Services in Warren, MI
Warren is the epicenter of automotive R&D in America. The GM Technical Center, General Motors’ global research and development headquarters, employs over 19,000 people on a sprawling campus that drives vehicle design, engineering, and testing for the world’s largest automaker. Adjacent to the Tech Center, a dense network of Tier 1 and Tier 2 automotive suppliers, including operations from Stellantis, Faurecia, and Continental, form one of the most concentrated supplier ecosystems in North America.
The U.S. Army TACOM (Tank-automotive and Armaments Command) further anchors Warren’s economy with a significant defense presence, creating demand for defense contractors and precision manufacturers who must navigate government contract accounting and FAR compliance. Michigan’s flat 4.25% income tax applies to all pass-through entity income, and the state’s flow-through entity tax election provides a mechanism to bypass the federal SALT cap for S-Corp owners with substantial Michigan-source income.
SDO CPA works with Warren business owners in automotive supply, defense contracting, and precision manufacturing to structure entities, claim R&D credits for product development and process improvements, and manage OEM payment cycle cash flow. Whether you’re a Tier 1 supplier serving the GM Tech Center or a defense subcontractor working with TACOM, 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. Warren automotive suppliers should evaluate Michigan’s flow-through entity tax election to bypass the federal SALT cap, potentially saving $3,000-$12,000 for S-Corp owners with $200K+ in Michigan-source income. Businesses claiming R&D credits for automotive product development should maintain detailed documentation of qualifying activities including tooling design and process engineering.
