RSU and Stock Compensation Tax Basics
RSUs are usually taxed as ordinary income when they vest, and later share sales can create capital gains or losses from the vesting-date value. Patterns differ by country and plan. This is a vocabulary guide for employees researching what happens after vesting - not payroll advice.
Vesting is often the income event
In many U.S.-style plans, the fair value of shares at vesting is treated as wages, with withholding. Your basis in the shares often starts at that included amount. Other countries use different employment-income rules for equity awards.
After you hold the shares
If you keep vested shares in a taxable account, later price moves can create capital gain or loss when you sell. Holding period for preferential rates may start at vesting in common U.S. storytelling - confirm plan and local law.
Sell-to-cover and diversification
Companies often withhold shares or sell a portion for tax. What you keep is concentrated employer stock - a portfolio risk topic as much as a tax topic. Estimated taxes can matter if withholding was light relative to your bracket.

Simple illustration
Educational numbers only - not your return.
RSUs vest when the share is $50; $50 per share is included as income (simplified). You later sell at $65. Many systems treat $15 as a post-vesting capital gain character question - subject to local employment-share rules.
Common mistakes
- Forgetting vesting income and only tracking the sale.
- Assuming options, RSUs, and ESPPs share one tax template.
- Ignoring double taxation risk across countries if you moved.
- Treating this guide as your plan’s legal summary.

Guide FAQ
Short answers for discovery.
Are RSUs taxed when granted?
Often the bigger employee-income event is vesting, not grant - but plans and countries differ. Read your grant documents.
Is this the same as NSO or ISO tax?
No. Options have their own exercise and AMT-style conversations in some systems. Keep award types separate.
Can StockWatch model my RSU vest?
No. We do not connect to payroll or plan administrators.
