Are R&D Tax Credits
Available in New Hampshire?

Yes. New Hampshire offers a permanent R&D Tax Credit against the Business Profits Tax (BPT) and the Business Enterprise Tax (BET). The credit applies to qualified manufacturing research and development expenditures (wages that also qualify under IRC §41) incurred within New Hampshire.

Credit is first applied against the BPT, with any excess applied against the BET.

If statewide claims exceed $7 million in a year, credits are reduced proportionally.

Carryforward:

Unused credits may be carried forward for 5 years.

Unitary businesses are treated as one taxpayer when claiming the credit.

Credit amount is the lesser

10% of qualified manufacturing R&D expenditures over the base amount, or

$50,000 per taxpayer.

Application process

Submit Form DP-165 to the New Hampshire Department of Revenue Administration (NH DRA).

Must be postmarked by June 30 following the taxable year in which R&D occurred.

Attach Federal Form 6765.
