How to use the lottery tax calculator

If you've had the good fortune of a lottery win, our lottery tax calculator can help you understand the tax implications. Here's how to make the most of this tool:

  1. Input annuity payout: Begin by entering the total annuity payout amount you've won in the lottery.

  2. Determine lump sum payout: If you opt for a lump sum, specify the percentage of the total annuity value you will receive upfront.

  3. Select tax treatment: Choose the appropriate tax treatment based on your situation. This could be the default US taxes (steps 4 and 5) or customizable tax rates, depending on the options provided.

  4. Set your Federal filing status: Select your federal filing status, such as single, married, filing jointly, or head of household, which will affect the federal tax calculation.

    Check which tax bracket you are in with our tax bracket calculator.

  5. Choose your state: Indicate the state where you reside, as state tax rates can vary significantly from one state to another.

  6. View results and annuity schedule: The calculator will display both the gross payout and the net payout after federal and state taxes are deducted.

    It will also show an annuity schedule if you choose to receive your winnings as an annuity, detailing the gross payment, taxes deducted, and net payment for each year.

This calculator can also perform reverse calculations:

  • If you know the net payout and the taxes applied, you can work backward to find out the gross payout.
  • You can adjust the lump sum payout percentage to see how different options affect your taxes and net income.

For example, on a $100,000,000 annuity payout with a 52% lump sum option, the calculator shows a lump sum payout of $52,000,000. If you're a single filer living in Arizona, it calculates Federal taxes at around $19,200,332 and state taxes at $2,600,000, leaving you with a net payout of approximately $30,199,668.

Whether you're considering taking a lump sum or annuity payments, this tool will help you plan for your new financial landscape, taking into account the complexities of lottery winnings and tax treatments.

How much is lottery tax? Tax on lump sum vs. annuity lottery

While the same type of taxes are levied on lump sum and annuity payouts, the final amounts you may receive can diverge considerably. First of all, the lump sum payment is typically lower than the advertised lottery prize (usually by around 52 percent) and is subject to an automatic 24 percent federal withholding tax.

The remainder of the amount is also reduced by the additional Federal tax (up to 37 percent) depending on your filing status, lottery purchase, and place of residence.

In the case of lottery annuity payments, the same taxes are levied; however, they are paid annually and are always based on the actual tax rates of the given year.

Behind the scenes of the lottery tax calculator

I'm Tibor, a PhD in statistical methods in economics, and the architect of the lottery tax calculator.

The inspiration for this calculator stemmed from my keen interest in finance, leading to the creation of a tool that demystifies the tax obligations associated with lottery winnings. Recognizing the complexities winners face, I aimed to facilitate informed decision-making regarding payout options and tax liabilities.

My extensive knowledge has been instrumental in ensuring the calculator accommodates various tax scenarios, from federal to state-specific considerations. It serves as a reliable resource for winners to forecast their net earnings and plan accordingly.

Trust in the lottery tax calculator comes from our rigorous standard of accuracy and my financial acumen. The tool undergoes regular updates to reflect the latest tax codes and is verified for precision, providing users with confidence in their financial planning post-lottery win.


What are the lump sum lottery winnings after taxes?

The federal tax on the lottery is determined by the federal marginal rates, which is 37 percent in the highest bracket. In practice, there is a 24 percent federal withholding of the gross prize, plus the remaining tax, based on your filing status.

For example, if your gross prize is $1,000,000, you need to pay $334,072 in total taxes ($240,000 federal withholding, plus the remaining $94,072 for single filing status in 2021).

How do I calculate lottery lump sum after taxes?

To find lump sum lottery winnings after taxes:

  3. Additional federal tax is imposed according to your filling status.
  4. In most cases, state taxes are also levied depending on where you bought the lottery and where you live.
