Fractional CFO & Controller Services for Businesses in Detroit and Southeast Michigan

Fractional CFO Services in Detroit

Fractional CFO and controller services for Detroit construction, contractors, distribution, manufacturing, and service businesses.

Southeast Michigan

Fractional CFO and Controller services for Detroit-area businesses.

Vessel Advisors supports businesses across Metro Detroit and Southeast Michigan — tier 2 and tier 3 auto suppliers, industrial and durable-goods manufacturers, family-owned mid-market operators, and distribution and logistics businesses . Our team includes CFOs and Controllers local to Detroit, backed by a vetted national bench of senior finance leaders who support businesses that need expert help.

Detroit's mid-market has been reshaping itself since the last cycle. Auto supply chain remains the anchor, but the base is broader and more diversified than the outside narrative suggests — and the EV transition is a live finance-function conversation for almost every supplier north of $10M.

The Market

Detroit is one of the deepest industrial mid-markets in the country — and the operator mix is broader than the auto-only story implies.

Southeast Michigan's business base sits on top of one of the most concentrated industrial supply chains in the world. Tier 2 and tier 3 auto suppliers dominate the mid-market, but the base also includes specialty industrial manufacturers, defense-adjacent operators, durable-goods producers, and a large distribution and logistics cluster serving the Great Lakes region. Family ownership runs deep — multi-generational operators in the second, third, or fourth generation are the rule here, not the exception.

The finance-function conversations reflect that. Auto suppliers are navigating an EV transition that reshapes program economics quarterly. Family-owned industrials are preparing for generational transitions or first-time sponsor conversations that require reporting they've never built. Distribution and logistics operators managing multi-warehouse complexity often lack consolidated financial visibility. And PE-backed platforms — more of them every quarter — expect institutional-grade reporting from day one.

What we see most:

  • Tier 2 and tier 3 auto suppliers managing program mix, EV transition economics, and OEM concentration risk.
  • Specialty industrial and durable-goods manufacturers with inventory, cost accounting, and margin discipline needs.
  • Multi-generational family-owned operators preparing for generational or sponsor transitions.
  • Distribution, logistics, and warehousing operators managing multi-facility complexity.
  • PE-backed platforms rolling up specialty industrials and services across the Great Lakes region.
  • Construction contractors and specialty trades serving the broader regional build-out.

Industries

Where we work most in Michigan.

Auto supply chain and specialty manufacturing

Tier 2 and tier 3 auto suppliers, specialty metal and plastic manufacturers, and defense-adjacent producers. Program economics, OEM concentration, EV transition planning, standard cost, and the margin visibility current-cycle diligence requires. Our manufacturing case study shows the pattern.

Industrial and durable-goods manufacturing

Industrial equipment, durable-goods producers, and specialty industrials serving the Great Lakes industrial base. Inventory accuracy, gross margin visibility, and standard cost discipline are the recurring pressure points.

Family-owned mid-market operators

Multi-generational family businesses across industrial, distribution, and services. Second- and third-generation transitions, first-time sponsor conversations, and the reporting maturity strategic buyers and institutional investors expect. More on how we serve family-owned businesses.

Distribution, logistics, and construction

Regional distributors, third-party logistics operators, warehousing platforms, and commercial construction contractors serving the Great Lakes economy. Multi-warehouse consolidation, working capital, WIP accounting, and margin discipline through the supply chain.

Michigan Taxes and Compliance

Michigan declined the 2025 federal write-offs. Detroit taxes S corporations as corporations.

Michigan's rates are flat: 6% on corporate income, 4.25% on individual income and 6% on sales. What a Detroit company owes turns on the 2025 federal changes the state left out, the city's own income tax, and employer rules the Legislature rewrote in 2025.

Taxes

Federal conformity

Research costs still amortize over five years

2025 PA 24, signed October 7, 2025, keeps Michigan off most of the 2025 federal law's business provisions. Domestic research costs are still spread over five years, and the federal transition rules, including the small-business option to expense them back to 2022, don't apply. Section 179 stays at the old limit, $1.25 million for 2025, and the interest limit is figured without adding back depreciation.

Bonus depreciation

None for C corporations, 40% for pass-throughs in 2025

The corporate income tax has never allowed bonus depreciation. Individual returns and the flow-through entity tax follow the pre-2025 phase-down instead of the federal 100%. The new federal write-off for qualified production property applies to none of Michigan's income taxes.

Income tax

6% corporate, 4.25% individual in 2026

Both rates are flat. Partnerships, S corporations and LLCs taxed as partnerships pay no corporate income tax, and a company with apportioned gross receipts under $350,000 owes none. Michigan levies no franchise, net-worth or gross-receipts tax.

Flow-through entity tax

4.25%, elected only by electronic payment

S corporations and partnerships can pay Michigan tax at the entity level, and their members get a refundable credit for it. The election is a payment through Michigan Treasury Online, due by the last day of the ninth month after the tax year ends. It binds the business for that year and the next two.

Research credit

Refundable from 2025, then prorated

Michigan's credit covers research done in the state from tax year 2025, and it is refundable. A $100 million statewide cap, with $25 million reserved for smaller employers, led Treasury to allow 2025 claims at 50.96% for companies with 250 or more employees and 59.88% for smaller ones.

Sales and use tax

6% everywhere in Wayne, Oakland and Macomb

Cities and other local units can't levy a sales tax, so Detroit's rate is the state rate. Motor fuel came out of the sales tax on January 1, 2026 and now carries a motor fuel tax of 52.4¢ a gallon for 2026. Remote sellers collect once they pass $100,000 in Michigan sales or 200 transactions in the prior year.

City income taxes

Detroit income tax

2.4% for residents, 1.2% for nonresidents

Residents pay on all income, nonresidents on income earned in Detroit. Every employer with a Detroit location, or doing business in the city without one, withholds it and files monthly or quarterly with Michigan Treasury, which administers the city tax. The annual reconciliation is due the last day of February.

Detroit corporate income tax

2.0%, and S corporations pay it

S corporations pay no Michigan corporate income tax, but Detroit taxes them as corporations. Every corporation doing business in the city files a return, with or without an office there, by the 15th day of the fourth month after year end. Quarterly estimates are required once the liability exceeds $250.

Nearby cities

Highland Park, Hamtramck and Pontiac tax income too

Highland Park taxes residents and businesses at 2.0% and nonresidents at 1.0%, and accepts paper returns only. Hamtramck taxes nonresidents at 0.5%, and Pontiac levies its own city income tax. No city in Macomb County levies one, and no county does.

Employers

Minimum wage

$13.73 an hour in 2026, $15.00 in 2027

The statute sets the $15.00 rate for January 1, 2027, and inflation indexing starts with the 2028 rate. Cities can't set their own minimum, so employers across Detroit, Oakland and Macomb pay the state rate. The tipped cash wage is $5.49 when tips bring pay to at least $8.24.

Earned sick time

One hour for every 30 worked

Employers with 11 or more employees can cap annual use at 72 hours, and those with 10 or fewer at 40, counting part-time, temporary and agency workers. Small businesses came under the law on October 1, 2025. Cities can't add sick-leave rules of their own.

Unemployment insurance

$9,000 wage base, 5.0% for new construction employers

The 2026 base is $9,000 per employee for employers with no unpaid balance and $9,500 for those owing $25 or more. New employers pay 2.7%. New construction employers pay the construction-industry average instead, 5.0% for 2026.

Hiring questions

Cities can't regulate salary-history questions

State law, as amended by 2018 PA 84, bars cities and counties from regulating what employers ask on applications or in interviews, salary history included. Detroit and its suburbs can't add hiring-question rules of their own.

Unclaimed property

Paychecks over $50 are presumed abandoned after one year

Holders report and remit by July 1 for the 12 months that ended March 31. Holders send due-diligence letters for items of $50 or more 60 to 365 days before filing. Paychecks of $50 or less fall outside the act.

Questions Detroit owners ask

Does Detroit tax my company if we don't have an office in the city?

Every corporation doing business in Detroit files a city corporate return whether or not it has an office there, and S corporations file as corporations at 2.0%. A partnership files its own annual city return, due the 15th day of the fourth month after year end, and its partners are taxed at the individual rates. An employer doing business in Detroit without a location there still withholds the city tax.

How does Michigan tax construction contractors?

A contractor is the consumer of the materials it affixes to someone else's real property. It pays sales tax when it buys them, or 6% use tax if none was charged, and it can't bill the tax to the customer separately. It can build the tax into its price as overhead, and a general contractor isn't liable for an independent subcontractor's use tax. More on fractional controllers for construction companies.

What are the construction lien deadlines in Michigan?

The owner records a notice of commencement before work starts. Subcontractors and suppliers serve a notice of furnishing within 20 days of first furnishing; a general contractor working directly for the owner needs none. A late notice doesn't void the lien, but it reduces the lien by payments the owner made under sworn statements or waivers before receiving it. The claim of lien is recorded within 90 days after last furnishing, and the foreclosure suit is filed within one year of recording.

How are payments on a Michigan construction job protected?

Under the Builders' Trust Fund Act, money paid to a contractor or subcontractor for building construction is a trust fund for the payer, laborers, subcontractors and suppliers, and the contractor is the trustee. On public work, the agency may retain up to 10% until the job is 50% in place, then no more unless progress is unsatisfactory or for a specific cause. Retainage sits in an interest-bearing account and is released with the final payment. Contracts with MDOT, school districts, community colleges and MSHDA, and contracts under $30,000, fall outside that retainage rule.

Can a buyer inherit the seller's unpaid Michigan taxes?

Yes, for every tax Treasury administers under the Revenue Act, not only sales tax. The buyer has to escrow enough of the purchase money to cover the seller's unpaid taxes, interest and penalties until the seller produces a Treasury receipt or a certificate that nothing is due. With the seller's written waiver, Treasury discloses what is owed within 60 days, and an escrowing buyer owes no more than that amount, or nothing if Treasury misses the deadline. A buyer who skips the escrow is personally liable up to the business's fair market value, less proceeds applied to superior secured debt. More on the first months of a newly acquired business.

Are non-compete agreements enforceable in Michigan?

Yes, when they protect the employer's reasonable competitive business interests and are reasonable in duration, geography and type of work. A court may narrow an unreasonable covenant and enforce it as limited. Michigan sets no salary threshold or notice requirement for them.

Do we owe personal property tax on our equipment?

Michigan taxes business personal property, but a company whose commercial and industrial personal property in a city or township, counting related entities, has a true cash value under $180,000 is exempt. Under $80,000, a one-time Form 5076 filed with the city or township by February 20 of the first year claimed keeps the exemption in place. Between $80,000 and $180,000, the company files the personal property statement and the Form 5076 attestation every year by February 20. Late claims go to the March Board of Review.

How is Michigan's research credit calculated?

Companies under 250 employees get 3% of qualifying Michigan research expenses up to the base, the average of the prior three calendar years, plus 15% above it. Companies with 250 or more get 3% plus 10%, and expenses incurred with a Michigan research university add 5%, each with its own cap. C corporations claim the credit against the corporate income tax and flow-through entities against withholding, with the tentative claim due March 15 after each calendar year.

Detroit Finance Talent

Detroit is the 14th-largest U.S. metro. Its financial managers earn a median $160,240.

The Bureau of Labor Statistics counts 11,670 financial managers, the category that covers controllers and finance directors, in the Detroit-Warren-Dearborn metro. Their median pay is $160,240, 3.8% below the national median of $166,570. The top tenth earns $285,500 or more, against $323,270 nationally.

The metro has 5,859 business locations with 50 to 499 employees, and they recruit from the same 11,670 financial managers. A company that needs CFO judgment doesn't have to win that hiring market to get it.
