What the calculator leaves out
Federal tax stacks the prize on wages after the 2026 standard deduction and taxes it at the ordinary brackets. Withholding treats the whole prize as winnings, though the IRS tests winnings minus the wager. The calculator takes the cash received this year: a lump sum is taxed in full the year it is paid, and annuity payments are taxed each year as they are received. Gambling losses are left out; only filers who itemize can deduct them, and from 2026 only up to 90% of losses. Tax another state may charge on a ticket bought there is left out.
