Manufacturing Accounting and Tax Services in Metro Detroit

Manufacturers in Metro Detroit face the same core financial questions as plants anywhere: true product and job profitability, reliable monthly reporting, inventory valued consistently, cash flow that matches reported profit, and pricing decisions backed by cost data. The difference locally is proximity: an advisor who can visit the plant, understand the operation and work alongside the owner.

Pagac works with manufacturers on cost accounting, inventory, financial reporting, cash-flow management and the analysis behind pricing, capital purchases and growth decisions, from its office at 1750 S Telegraph Rd in Bloomfield Hills.

Michigan levies a 6 percent corporate income tax on C corporations, a 6 percent sales and use tax, and property taxes that vary by locality. Manufacturers have specific sales and use tax considerations around production equipment, tooling and materials, and the exemptions and rules depend on how the property is used.

Federal strategy matters too: for 2026, Section 179 expensing is capped at $2,560,000 with a phase-out beginning at $4,090,000 of qualifying purchases, and 100 percent bonus depreciation applies to qualified property. Domestic research costs are immediately deductible under the rules enacted by the One Big Beautiful Bill Act. Whether these apply depends on the company's entity, property and circumstances.

Pagac & Company is a CPA, tax, accounting and business advisory firm founded in 1975, located in Oakland County at 1750 S Telegraph Rd Suite 203, Bloomfield Hills, MI 48302. The firm serves manufacturers in Metro Detroit, Southeast Michigan and beyond, with a national specialty practice for manufacturing companies.

The firm operates from this single verified office and does not maintain offices in other cities. For qualifying manufacturers beyond the immediate market, engagements are supported from the Bloomfield Hills office, which is an important distinction for owners who value a dedicated advisor rather than a network of remote offices.

Before year-end, a manufacturer should review equipment purchases against Section 179 and bonus depreciation rules, confirm domestic R&D documentation for immediate expensing and the R&D credit, check sales and use tax positions on recent purchases, and update cash-flow and profit forecasts with the latest cost and margin data.

Pagac's case study of a Metro Detroit electrical-parts manufacturer shows why the review matters: an accounting-system error had effectively counted the same labor cost twice, creating almost $250,000 in false cost swings, and the corrected reports revealed that rising copper costs were eroding margin on two strong-selling products. Reliable numbers come first; strategy follows.
