> The lottery tax calculator estimates how much of a U.S. lottery jackpot you keep after federal and state taxes – for the lump sum and the 30-year annuity – including the 24% federal withholding and the extra tax due at the top 37% bracket.

## Inputs

- Advertised jackpot (annuity value)
- Lump sum (cash option) percentage (%)
- Federal filing status
- State tax rate on lottery winnings (%)

## Results

- Lump sum before tax
- Federal withholding (24%)
- Total federal tax on the lump sum
- State tax on the lump sum
- Lump sum after taxes
- Extra federal tax due beyond withholding
- First annuity payment before tax
- First annuity payment after tax
- Total annuity after tax (30 payments, approx.)

## Formula

```
Lump sum = jackpot × cash option %
Federal withholding = 24%; actual federal tax ≈ 2026 brackets on the prize (top rate 37%)
State tax = prize × state rate
Annuity: 30 payments growing 5% a year (first ≈ jackpot × 1.5% )
```

## Explanation

Lottery prizes over $5,000 have 24% federal tax withheld, but big prizes fall in the 37% bracket, so winners owe more at tax time. Some states – such as California, Florida and Texas – don't tax lottery winnings; others charge up to about 11%.

### How to use the Lottery Tax Calculator

- **Advertised jackpot (annuity value)**
- **Lump sum (cash option) percentage**
- **Federal filing status**
- **State tax rate on lottery winnings**

Results update as you type, and every field accepts the units shown in its menu.

### How it works

Enter the advertised jackpot, the cash option percentage, your filing status and your state's tax rate on lottery winnings.

### Tips

- Tax figures here are estimates for planning – your actual tax depends on credits, deductions and local rules.
- Check the tax year and filing status before you rely on a result.
- Use gross (before-tax) figures unless a field asks for take-home pay.
- When in doubt, confirm with the tax authority's own calculator or a tax professional.

### Common mistakes to avoid

- Confusing marginal and effective tax rates.
- Adding sales tax to a price that already includes it.
- Forgetting payroll taxes (Social Security and Medicare) on wages.

### What each result means

- **Lump sum before tax** = [Advertised jackpot (annuity value)]×[Lump sum (cash option) percentage]÷100
- **Federal withholding (24%)** = [Lump sum before tax]×0.24
- **State tax on the lump sum** = [Lump sum before tax]×[State tax rate on lottery winnings]÷100
- **Lump sum after taxes** = [Lump sum before tax] - [Total federal tax on the lump sum] - [State tax on the lump sum]
- **Extra federal tax due beyond withholding** = [Total federal tax on the lump sum] - [Federal withholding (24%)]
- **First annuity payment before tax** = [Advertised jackpot (annuity value)]×0.05÷((1.05)^30 - 1)
- **Total annuity after tax (30 payments, approx.)** = [Advertised jackpot (annuity value)]×(1 - 0.355 - [State tax rate on lottery winnings]÷100)
