RSU Tax Calculator
This view compares the flat RSU withholding convention with the likely full tax drag from a vest event so you can see whether the sell-to-cover result is likely to under-withhold or over-withhold.
Vest value left after modeled income and payroll taxes.
Incremental federal, state, and FICA tax created by the vest event.
Positive suggests the default supplemental withholding may leave more tax due later.

| Scenario | Primary | Secondary | Interpretation |
|---|---|---|---|
| Default supplemental rate | $6,600 | $3,988 | Base check for whether default withholding is likely to land near the true tax bill. |
| Higher withholding | $8,100 | $2,488 | Useful when you prefer to over-withhold slightly rather than face a later balance due. |
| Net proceeds focus | $19,412 | 35.3% | Useful for deciding how much of the vest still behaves like spendable cash after tax. |
How to read the result
- RSU withholding conventions are often simpler than the final tax reality created by your full income picture.
- The important comparison is actual incremental tax versus what the employer withholds at vest.
- A vest can feel like a raise in shares but behave like supplemental wage income for tax timing.

Method, Scenario, and Planning Cautions
Use these cards to see what the estimate is anchored to, where the main comparison sits, and which assumptions deserve a second look.
Review the main result from rsu tax calculator before comparing a second scenario.
The chart view is designed to show where the cost, tax, or coverage stack is concentrated.
The scenario table helps you pressure-test how the answer changes when you adjust one assumption at a time.
Planning Cautions
- Broker withholding defaults may not match the final marginal rate owed at filing time.
- Concentrated single-stock exposure can make the net-keep decision more important than the tax estimate itself.
- State tax, local tax, and employer payroll treatment can widen the gap from a federal-only model.
Built for employees receiving restricted stock unit compensation. Use this page for estimating withholding, sell-to-cover impact, and after-tax cash from an RSU vest, then compare at least one lower-friction and one higher-protection scenario before you act.
How the result is built
How This Page Helps You Compare Options
The calculator is tuned for finance-style decisions: it breaks results into components, shows a scenario ladder, and surfaces the gap that usually matters most for a real-world choice.
Use the first KPI to see whether the current plan leaves an uncovered loss, tax shortfall, or cash-flow mismatch.
Review the chart and scenario table to compare premium, deductible, withholding, or payout changes without losing context.
Adjust one assumption at a time so you can see whether the decision is robust or just dependent on one optimistic input.
This mode shapes the inline chart inside the calculator so the output looks more like a finance decision dashboard than a plain result box.

How to read the result
Treat the headline number as a planning anchor, not a final quote. The supporting cards and comparison rows show which levers are actually moving the result.
The most useful result on this page is usually the gap: uncovered risk, cash-flow drag, or withholding shortfall.
- Use the KPI cards to find the first decision you need to make.
- Use the chart or ladder to see where cost, tax, or coverage is concentrated.
- Use the scenario table to compare a low-friction option against a stronger-protection option.
