The National Register of Historic Places does not have a tax or grant program ourselves. However, Technical Preservation Services (a different division of the National Park Service, Cultural Resources Directorate) does have a tax credit program that may be of assistance to you. The website for the tax credit program is: https://www.nps.gov/subjects/taxincentives/about.htm
Additionally, sometimes State historic preservation offices may have state run programs that could help. You can find contact information for the SHPOs at http://www.nps.gov/nr/shpolist.htm
