Why Withholding Is Not the Same as Final Tax
Large lottery prizes may have federal withholding taken out before payment, but withholding is only a prepayment. The final tax bill can be higher or lower depending on taxable income, filing status, state rules, local taxes, deductions, and timing.
Some states do not tax lottery winnings. Others apply state income tax or special rules. Always confirm the exact result with the state lottery, IRS guidance, and a qualified tax professional before making financial decisions.
