If a jackpot gets split among a group — an office pool, family, or friends — here's roughly what each person's share works out to after estimated tax.

Net share
This is a simplified estimate for informational purposes only, not tax advice. It calculates federal tax using approximate progressive brackets applied to each person's individual share (which is more accurate for group splits than assuming everyone lands in the top bracket) but ignores filing status, deductions, other income, and current-year bracket updates. Splitting a real prize requires formally documenting each person's share with the lottery at the time of claiming — see our guide on lottery office pools for how that works.
Why Each Person's Tax Rate Can Differ From the Full Jackpot's
Our main tax calculator assumes a single winner and applies the top 37% federal bracket, which is realistic for any jackpot-sized prize going to one person. But when a jackpot is split many ways, each individual share can be small enough to land in a lower federal bracket entirely — splitting $100 million ten ways is $10 million each (still top-bracket territory), but splitting a $2 million Lotto America-style jackpot twenty ways is $100,000 each, which is taxed very differently. This calculator applies real progressive brackets to each share rather than assuming everyone is a top-bracket taxpayer.
