New Hampshire R&D Tax Credit Summary

The New Hampshire R&D Tax Credit offers taxpayers a permanent research and development credit against the business profits and business enterprise taxes. The credit is for qualified manufacturing research and development expenditures made or incurred within New Hampshire during the fiscal year. The expenditures are defined as wages provided that the wages qualify for the federal credit under IRC §41.

In New Hampshire, a Research & Development tax credit is allowed for qualified manufacturing R&D expenditures made or incurred during the fiscal year, however: The aggregate of tax credits issued to the taxpayers must not exceed

  • $2 million after May 20, 2013 and before July 1, 2017; and

  • $7 million starting on July 1, 2017

In the event that the aggregate amount of credit applied for, in any given fiscal year, exceeds the aggregate period's tax credit cap, all credits for that year will be allocated and reduced proportionately.  The credit is first applied against the business profits tax, and any remaining amount may be applied against the business enterprise tax.​
