Lottery Tax Calculator
A 1,000,000 dollar jackpot taken as a lump sum at 60% cash value leaves about 378,000 dollars after 37% federal tax. This lottery tax calculator estimates your take-home pay for both the lump-sum cash option and the full annuity, so you can see how federal and state tax reshape a headline jackpot before you decide.
Quick answer
The advertised jackpot is the annuity total paid over many years, not cash in hand.
What this tells you
- •The advertised jackpot is the annuity total paid over many years, not cash in hand.
- •The lump sum is the cash value, often around 60% of the advertised amount.
- •Federal tax withholds 24% upfront, but large jackpots reach the top marginal rate of 37%.
- •State tax varies widely, from 0% in states with no income tax to over 10% in others.
How to Use
- 1Enter the advertised jackpot amount.
- 2Enter your state tax rate as a percent (use 0 if your state does not tax winnings).
- 3Adjust the federal rate and lump-sum cash value share if you want a different scenario.
- 4Calculate to compare the lump-sum take-home against the annuity net.
How It Works
Formula
Lump-Sum Net = (Jackpot x Cash Value %) - Federal Tax - State TaxThe lump sum is the advertised jackpot multiplied by the cash value share. Federal and state tax are applied to that cash value to find the take-home. The annuity option taxes the full advertised jackpot at the same rates without the cash-value discount.

Worked Examples
1 million dollar jackpot, no state tax
The 60% cash value is 600,000 dollars. A 37% federal tax removes 222,000 dollars, leaving 378,000 dollars.
Same jackpot with a 5% state tax
The 5% state tax adds 30,000 dollars on the 600,000 dollar cash value, lowering the take-home to 348,000 dollars.
Common mistakes
- Assuming the advertised jackpot is the cash payout. The lump sum is the smaller cash value.
- Planning around the 24% federal withholding. Large jackpots owe up to 37% at filing time.
- Forgetting state tax. It can remove another 10% or more depending on where you live.
Limitations
This calculator uses flat federal and state rates you enter, not graduated tax brackets or filing-status details. It does not model local taxes, non-resident withholding, deductions, gift or estate planning, or the way annuity payments are taxed in the year each installment is received. Cash value shares change with interest rates and vary by game.
