What it does
This bill expands the federal research and development (R&D) tax credit for small businesses by raising the income threshold for eligibility from $10 million to $25 million in gross receipts, increasing the credit rate from 14% to 20% for qualified small businesses, and making the credit refundable against unemployment taxes. It also indexes the credit amounts for inflation starting in 2027, allowing small firms to claim larger tax breaks for R&D spending.
Why we flagged it
The bill's primary function is to expand and simplify the R&D tax credit for small businesses, making it more generous and easier to claim. This is a targeted tax expenditure designed to encourage private investment in research and development.
What the text implies
- The refundability against unemployment taxes (Section 3111) may reduce payroll tax revenue, shifting the cost burden to other taxpayers or reducing funds available for unemployment insurance programs.
- Raising the gross-receipts threshold to $25 million expands eligibility to mid-market firms that may not be considered 'small' in traditional SBA definitions, potentially benefiting larger private equity-backed companies.
