Frequently Asked Questions
Why does my Schwab or Fidelity 1099-B show a $0 basis for my RSUs?
IRS regulations prohibit brokerages from automatically including W-2 compensation income in the cost basis reported on Form 1099-B Box 1e. If your CPA does not manually adjust Column (g) on Form 8949, you will pay capital gains tax on money that was already taxed on your W-2.
How do I prevent a huge tax bill when my RSUs vest?
The default federal RSU withholding rate is 22%, but high earners in Sunnyvale are usually in the 35% or 37% tax bracket. To avoid surprise bills and IRS underpayment penalties, you can make quarterly estimated tax payments or adjust your W-4 withholding.
