California IPO windfall: taxes tangled by structure and timing
California could gain from SpaceX’s IPO and expected OpenAI/Anthropic debuts, but the tax windfall is likely smaller and less predictable than past IPOs. Key factors are RSU vesting tied to liquidity (which can trigger taxes earlier), private pre-IPO sales and tender offers that shift when revenue is realized, and tax strategies like donor-advised funds and stock-backed loans. State estimates depend on market timing and company behavior, and the rise of pre-IPO liquidity reduces the lump-sum tax hit historically seen with IPOs, making any gain a potential one-time boost rather than a steady stream.
