Michigan R&D Tax Credit Deadlines for Farms and Agribusinesses: What to Know for 2026

Michigan’s R&D Tax Credit creates a state-level opportunity for eligible farms, agribusinesses, processors, agricultural equipment companies, and other businesses with qualifying research activity in Michigan.

For agricultural businesses, the most important issue is timing. Michigan uses the calendar year in which Michigan Qualified R&D Expenses, or MQREs, are incurred to determine the application deadline. For 2025 expenses, the first statutory deadline was April 1, 2026. For 2026 expenses, the application deadline is March 15, 2027. Michigan Department of Treasury states that late applications are not accepted.

Since 2004, RCG Tax Partners has completed more than 25,000 R&D tax credit studies and identified over $750 million in tax savings. Its team includes CPAs, tax specialists, engineers, technical writers, and architects who support federal and state R&D Tax Credit studies with technical activity analysis, qualified expense review, and detailed supporting documentation.

The Deadline Depends on the Expense Year

Michigan’s filing schedule is straightforward once the expense year is identified.

Eligible businesses must submit the R&D Credit Application through Michigan Treasury Online before the applicable deadline. A timely application is required before the credit can later be claimed on the appropriate annual return.

Which Farms and Agribusinesses May Be Eligible?

The Michigan credit is available to eligible Corporate Income Tax filers and certain flow-through entities that are employers subject to Michigan withholding tax.

To qualify, a business must have Michigan Qualified R&D Expenses that exceed its base amount and must timely file the required application. Michigan Treasury also states that a business does not need to claim the federal R&D Tax Credit in order to qualify for the Michigan credit.

For agricultural businesses, potentially relevant projects may include:

• Crop or production-process testing
• Agricultural equipment development
• Feed or formulation work
• Irrigation or environmental systems
• Automation and controls
• Agricultural software
• Product or packaging development

The underlying activity still has to satisfy the applicable R&D requirements. Routine planting, harvesting, maintenance, or standard production does not automatically qualify.

Small and Large Employers Use Different Rates

Michigan divides claimants into small and large employers based on employee count.

A business with fewer than 250 employees throughout the expense year is treated as a small employer. If the business reaches 250 or more employees at any point during the expense year, it is treated as a large employer.

The standard credit is calculated as follows:

These are statutory calculation rules, not guaranteed credit amounts. The final allowed credit can also be affected by statewide proration. Michigan

Michigan Research University Projects Can Add Another Credit

Michigan also provides an additional credit equal to 5% of qualifying MQREs incurred in collaboration with a Michigan research university under a written agreement.

That additional credit is capped at $200,000 per claimant per year.

For farms and agribusinesses, this may be relevant when technical work is performed in collaboration with a Michigan university on crop science, processing, equipment, biological systems, or other qualifying research.

The Application Is Only Step One

Michigan’s process is more involved than simply calculating the credit and placing it on a return.

Step 1: Submit the R&D Credit Application

The business calculates its unadjusted credit using actual MQREs and files the application through Michigan Treasury Online by the statutory deadline. Late applications are not accepted.

Step 2: Wait for the Proration Notice

Step 3: Claim the Allowed Credit

After the applicable proration is known, the business claims the credit on the appropriate Corporate Income Tax or withholding tax return.

What Should Farms Track During 2026?

A farm planning to apply for the Michigan credit should not wait until March 2027 to reconstruct the year’s technical work.

Useful records may include:

Project records

Identify the crop, process, equipment, formula, software, or other business component being developed or improved.

Testing records

Keep field trials, engineering notes, test results, failed approaches, and production trials.

Employee activity

Track employees conducting, supervising, or directly supporting qualified research.

Supplies and contractor costs

Separate research-related costs from normal farm operating expenses.

Michigan location

Maintain records showing which qualifying research expenses were incurred in Michigan.
