About Lottery Tax Calculator
This calculator estimates net lottery winnings after basic federal and state taxes using a simplified model. Actual outcomes depend on the state where the ticket was purchased and where you reside, withholding rules, reciprocity agreements, local taxes, and whether you take cash or annuity. Cash options are typically a fraction of the advertised jackpot and may vary by game and market conditions. This tool is for educational planning and does not account for itemized deductions, additional surcharges, or special state rules. Consult official guidance or a tax professional before making financial decisions.
