The Michigan Research and Development Tax Credit, enacted under Public Acts 186 and 187 of 2024 and effective for tax years beginning on or after January 1, 2025, rewards businesses for increasing qualified research expenses conducted within the state. Administered by the Michigan Department of Treasury, this refundable credit uses the IRC section 41(b) definition of qualified research expenses but applies its own Michigan specific base and rate rules and only counts research conducted in Michigan.

How to Calculate the Michigan R&D Tax Credit

Michigan uses a single incremental method based on calendar-year state-sourced data, requiring calculation of a base amount as the average of prior QREs. Only Michigan QREs qualify, regardless of tax year.

Incremental Method
  • Determine total Michigan QREs for the calendar year (e.g., 2025).
  • Calculate base amount: Average Michigan QREs from the prior three calendar years (or fewer if applicable; zero if no prior).
  • Compute excess QREs: Current-year QREs minus base amount.
  • Apply rates: For 250 employees, 3% of QREs up to base + 15% of excess; for ≥250 employees, 3% up to base + 10% of excess.
  • Add university bonus (if applicable): 5% of collaborative QRE portion under written agreement.
  • Apply caps: $250K max for 250 employees; $2M max for larger; prorate if statewide claims exceed $100M.
Example Calculation
QREs (2025) =$1,000,000
Base (avg prior 3 years) =$600,000
Excess =$400,000
Credit (250 employees) = (3% × $600,000) + (15% × $400,000) = $18,000 + $60,000 =$78,000
University Collab ($200,000 of QREs) = +5% × $200,000 =$10,000
Total =$88,000 (below $250K cap)
For startups (no prior QREs): Base = $0, so credit =tiered rate on full QREs. Unitary groups calculate at group level but allocate pro-rata.
Base Calculation for Michigan R&D Tax Credit
Identify Michigan QREs for the prior 3 calendar years.
  • Compute average = (Year -1 QREs + Year -2 QREs + Year -3 QREs) / 3.
  • Apply as base amount (if fewer than 3 years, average available years; if no prior QREs, base = $0).
  • Use only Michigan-sourced QREs; calendar-year basis regardless of taxpayer's tax year.
Example Calculation
Prior Year -1 QREs =$900K;
Year -2 =$700K;
Year -3 =$500K;
→ Base = ($900K + $700K + $500K) / 3 =$700K
If no prior:
→ Base =$0 (full current QREs qualify as excess)
Important Notes on Base Calculation
  • Use only Michigan sourced qualifying R&D expenses (QREs) for both the base and the current year. Michigan does not use federal gross receipts or the federal Sec. 41 base formula
  • Employee count is based on IRC §3401(c) (withholding-eligible individuals) at the group level for unitary business groups
  • Fiscal-year filers: Treasury is developing an optional calendar-year conversion method for pre-2025 base years

Michigan-Specific Rules

Michigan's program emphasizes immediate liquidity through refunds and incentives for small businesses and university partnerships, with a focus on high-tech sectors like automotive and semiconductors.

High Incremental Rates for Small Businesses

Businesses with fewer than 250 employees benefit from a 15% rate on excess QREs, making this credit highly valuable for startups and mid-sized innovators. The $250K per-taxpayer cap supports scaling, with $25M of the $100M statewide allocation reserved for small taxpayers to ensure equitable access.

Fully Refundable Structure

Excess credit over tax liability is refunded in cash after other nonrefundable credits, providing immediate benefits without carryforwards. This structure suits R&D-heavy firms with low initial liability, subject to statewide proration.

University Collaboration Bonus

An extra 5% credit on qualifying collaborative expenses (up to $200K annually) incentivizes partnerships with Michigan public universities or independent nonprofits. Requires a written agreement, boosting claims in life sciences and engineering.

Other Rules
  • Tentative Claim: Submit actual data by April 1, 2026, for 2025; late ineligible. Proration notice via website; post-2025 deadline March 15
  • In-State Only: All QREs must be physically conducted in Michigan; unitary groups at group level
  • No Transfer: Credits non-assignable; entity-level for flow-throughs, no owner allocation
  • Audit: Retain 4 years (projects, time logs, agreements); IRC §41(b) substantiation
