How South Dakota lottery winnings are taxed
Lottery prizes are taxable income. Every winner pays federal tax — the IRS withholds 24% up front, and the true rate climbs to 37% on large prizes. South Dakota does not add a state tax on lottery winnings, so your only lottery tax is federal — one of the better states to win in. Taking the prize as a lump sum is taxed all in one year (pushing more into the top bracket); a 30-year annuity spreads the income out.
