Support Small Business Growth Act of 2025

This bill creates a new payroll tax deduction for qualifying small businesses, allowing them to deduct 12% of wages paid to designated low-wage employees. It directly affects small businesses meeting specific criteria: those with no more than 15 full-time employees, meeting gross receipts limits, and certifying compliance. The deduction applies only to the lowest-wage full-time employees (excluding high earners), with the number of eligible employees decreasing annually (starting at 10 in 2026 and ending at 4 in 2033). The provision expires after 2033 and applies to taxable years beginning after December 31, 2025.
