HB 5059 Connecticut House · 2026 Regular Session

AN ACT ESTABLISHING A RESEARCH AND DEVELOPMENT TAX CREDIT FOR PASS-THROUGH ENTITIES.

HB 5059 creates a 6% tax credit against personal income tax for pass-through entities (such as S-corporations, partnerships, and sole proprietorships) that incur research and development expenses. The credit directly applies to business owners who pay personal income tax, reducing their tax liability by 6% of qualifying R&D costs. Key provisions require businesses to pay or incur eligible R&D expenses during a taxable year to claim the credit. This policy change lowers the tax burden for small businesses and entrepreneurs investing in innovation, without altering tax rates or creating new regulations.
