About Jackpot Tax Calc
Jackpot Tax Calc answers one question well: after every tax, how much of a lottery prize or a year of gambling winnings do you keep, where you live?
Who we are
The site is written and maintained by the Jackpot Tax Calc Editorial Team, part of an independent publisher that also operates other free calculator sites on unrelated topics. There is no named author or reviewer because none exists: we do not invent credentials. We are not a lottery, not a law or accounting firm, not affiliated with any state lottery, the Multi-State Lottery Association, the Mega Millions consortium or any tax agency, and we do not sell tickets, financial products or leads.
Why it exists
Jackpot headlines quote the advertised annuity, and most quick calculators then subtract 24% and one state rate. That is wrong in both directions. Federal withholding is 24%, but a jackpot is taxed at 37%. Several states recapture their lower brackets (New York, Connecticut), add surtaxes (Massachusetts, Maine, California’s 1% on income above $1 million), exempt their own lottery (California) or small prizes (New Jersey), or cannot tax nonresidents at all (the District of Columbia). A winner who bought the ticket across a state line deals with two states. We built a calculator that models those rules one state at a time, using 107 primary sources — statutes, tax-agency tables and the lotteries’ own claim pages — each listed on our sources page.
How the site is funded
Jackpot Tax Calc carries no advertising, no affiliate links and no third-party trackers. The pages load nothing from other companies’ servers. We measure only first-party, anonymous counts (a page was viewed, a calculation was completed, which state was chosen) — never the amounts you type; the privacy page lists exactly what is stored.
What we will not do
We will not tell you whether to take the cash or the annuity, how to structure a trust, or how to claim anonymously beyond what each state’s lottery publishes. Those decisions turn on facts we cannot see. Use the numbers here to prepare questions for a CPA or attorney licensed in your state, and confirm withholding with the lottery when you claim.
Coverage
All 51 jurisdictions (50 states and DC) have their own page, built from that state’s sources and worked through that state’s own example. Federal figures are for tax year 2026. The methodology explains every step and every limit, and the editorial policy explains how figures are checked and corrected.
