KEY POINTS
  • A new tax proposal by Sen. Bernie Sanders raised concerns from Silicon Valley, including from a congressman leading his bid for the Democratic presidential nomination.
  • The proposal would tax nonqualified stock options of at least $100,000 at vesting for employees making at least $130,000.
  • Start-up employees are commonly offered stock options as part of their compensation packages to lure tech talent and critics of the bill fear it will make it harder for start-ups to compete with Big Tech companies for workers.

Vermont Sen. Bernie Sanders just introduced legislation that's raising alarms in Silicon Valley. But this time, it's start-up workers, not Big Tech executives, who may be concerned.

Sanders and Sen. Chris Van Hollen, D-Md., introduced a new tax bill Thursday that would tax nonqualified stock options of more than $100,000 at vesting for private company employees making at least $130,000 a year. This means that instead of being taxed once they exercise their options, employees would be taxed on shares when they vest, even though they still wouldn't be liquid assets. Employees who meet the tax threshold would be taxed on assets they haven't yet accessed and possibly will never exercise.
