Small Business Investment Act of 2025

This bill reduces the time period a noncorporate taxpayer is required to hold qualified small business stock (QSBS) before a percentage of the gain on the sale or exchange of such stock may be excluded from gross income. (Limitations apply.) The bill also expands QSBS to include qualified debt instruments and certain corporate stock.

Under current law, a noncorporate taxpayer may exclude from gross income 100% of the gain from the sale or exchange of QSBS acquired after September 27, 2010 (or a smaller percentage if acquired on or before such date) and held for more than five years. Further, under current law, QSBS must be C corporation stock. (Exclusions and other requirements apply.)
