Equity compensation guide
RSU and Stock Compensation Tax
RSUs and stock compensation can make income look much larger on paper while creating tax, withholding and cash-flow complexity. The key is understanding when shares are taxed, when cash is actually available, and how state rules can affect the final result.
Restricted stock units are commonly taxed as income when they vest.
Employer withholding can be too high or too low depending on total income and state exposure.
Future gains or losses after vesting can create capital gains questions.
How RSUs usually work
Restricted stock units are typically promised first, then taxed when they vest. At vesting, the share value is often treated as wage income, which can affect federal tax, payroll tax and state tax.
Why withholding can surprise people
Employers may sell shares to cover withholding or apply supplemental wage rules. For high earners, that withholding may not perfectly match the final tax bill, especially when salary, bonus and equity compensation combine.
Capital gains after vesting
Once shares vest and are taxed as income, later price movement can create capital gains or losses when shares are sold. That is a separate layer from the wage-income treatment at vesting.
State tax and relocation context
State rules can matter for equity compensation, especially if work location, residence or vesting periods cross state lines. Users with complex equity income should use this guide as orientation, not as a substitute for professional tax advice.
Where this fits in salary planning
Compensation complexity changes how useful a simple salary number is. These guides connect calculator results to real payroll situations without turning every salary page into a long technical explainer.

Practical interpretation
Use estimates carefully
Calculator outputs help with planning, but payroll settings and personal circumstances can move the final paycheck.
Compare net impact
Gross pay, bonus amounts or day rates are less useful until tax, benefits and timing are included.
Keep decisions grounded
The goal is better planning, not aggressive tax avoidance or unrealistic income promises.
Questions this page helps answer
Why can compensation feel different from the headline amount?
Tax, withholding, payroll timing, benefits, deductions and income variability can all change the money that actually reaches the bank account.
Should I use this instead of a calculator?
No. Use it with the calculators and salary pages. The guide explains why the result may differ from a simple salary conversion.
Does this apply to both UK and US users?
Some concepts are country-specific, but the main planning idea is shared: judge compensation by realistic take-home pay and timing.
When should I get professional help?
Complex equity, contractor income, tax residency, payroll disputes or self-employed situations are good reasons to check records and speak with a qualified professional.
Practical next-step context
This page works best as part of a wider salary-planning journey. Start with the estimate, then test what it means after tax, fixed costs and household commitments.
Use related AfterTaxTool calculators and assumption pages when comparing salaries, locations or monthly affordability. A single figure rarely captures the full financial picture. For transparency, use the methodology and tax assumptions pages alongside the result.
| Question | What to check | Why it matters |
|---|---|---|
| Income view | Separate gross pay from usable take-home pay. | Budgeting decisions usually depend on net income. |
| Cost view | Add housing, transport, debt and savings pressure. | The practical result is what remains after fixed costs. |
| Practical use | Compare the estimate with real income, bills and commitments. | The page should support planning, not create a false sense of precision. |
