Rural Historic Tax Credit Improvement Act

This bill increases tax credits for rehabilitating historic buildings in rural areas. It creates a new "applicable rural project" category: affordable housing projects get a 40% credit on rehabilitation costs (up to $5 million total), while other rural projects get a 30% credit. The credit can now be transferred to other taxpayers, unlike previous rules. It specifically targets buildings in areas outside cities over 50,000 people or adjacent urban zones, and requires affordable housing projects to maintain housing affordability standards. The changes apply to property placed in service after December 31, 2025.
