> Moving from current realization-based to accrual-based taxation would reduce founder ownership at exit by 25% on average but would also increase the fraction receiving positive payoffs from 16% to 47% when tax credits are refunded.
Founders would use VC money to pay the tax and get a refund if the startup fails, since the capital gains were never realized. Therefore "pre-paying" capital gains would be a good thing for most founders since otherwise a liquidity event wouldn't happen for 84% of them.
This only happens with a tax on unrealized capital gains, though, not a normal wealth tax.
Another corollary is that "zombie startups" would be heavily discouraged, since "failing fast" could result in a payout.
