The bipartisan SHARE Plan Act would give US companies with 500 or more employees a 3% corporate tax rate reduction if they grant stock at no cost to the lowest-paid 80% of their workforce, excluding top earners. Companies qualify by distributing at least 1% of their stock in a given year or 5% cumulatively, with stock grants subject to vesting but required to fully vest within five years and be freely transferable once vested. While the bill could significantly expand broad-based employee ownership, its success depends on whether the tax incentive outweighs the costs for companies, and its large potential budget impact may challenge passage.
