Maine R&D Tax Credits

Find out if you qualify for R&D tax credits in Maine and recharge your business.

Maine offers an R&D Tax Credit and a Sales Tax Exemption for businesses engaged in certain specialized industries. In general, Maine's Research Expense Tax Credit closely follow the federal R&D qualification guidelines and are applied for as part of a taxpayer's Maine corporate tax return.

Research Expense Tax Credit:
The credit is based on a percentage of the federal R&D Tax Credit under IRC § 41. The Maine R&D credit is calculated as:

  • 5% of the excess qualified research expenses (QREs) over the previous three-year's average QREs plus 7.5% of the basic research payments.
  • Credit utilization is limited to 100% of the first $25,000 in corporate tax liability plus 75% of the tax liability in excess of $25,000.
  • The credit cannot be carried back, but can be carried forward for up to 15 years.


Sales Tax Exemptions
Maine sales tax exemptions are available for expenses related to manufacturing, research and development, custom computer programming, fuel & electricity, and biotechnology.

  • Manufacturing:  Sales of machinery and equipment used by the purchaser directly and primarily in the production of tangible personal property for later sale or use is eligible for a sales tax exemption. In addition, items consumed or destroyed directly or primarily in production, and repair and replacement parts for qualified production equipment, are exempt from Maine sales tax.
  • Research and Development:  Expenses related to machinery and equipment used by the taxpayer directly and exclusively in research and development are eligible for a sales tax exemption.
  • Custom Computer Programming:  Any customized computer software purchased by a business is exempt from sales tax. Specifically, if a standard program is purchased, then customized, the cost of the standard program would be taxable and the customizing, if separately stated, would be tax-exempt.
  • Fuel & Electricity For Use In Manufacturing:  Manufacturers are exempt from paying 95% of the sales tax on fuel and/or electricity used in the manufacturing operation.
  • Biotechnology:  Expenses for machinery, equipment, instruments, and supplies used by the purchaser directly and primarily in a biotechnology application are eligible for a sales tax exemption.
