Research and Development Tax Credit Program
The New Hampshire Research and Development (R&D) Tax Credit Program was established in 2007 by Senate Bill 134 (Chapter 271, Laws of 2007)
Through FY2013, the maximum credit allowed for all taxpayers was $1,000,000 per fiscal year. The annual limit was increased to $2,000,000 in FY2014, and then to $7,000,000 in FY2017. The credit is based upon 10% of the excess of the qualified R&D expenses for the taxable year over the base amount. Wages for which a credit is taken shall not also be eligible under the ERZTC (RSA 162-N:7). Each taxpayer's share of the R&D tax credit shall not exceed $50,000 per fiscal year. Each credit shall be used to offset the taxpayer's tax liability within the subsequent 5 tax years.
