Oregon Lottery Tax Calculator - 10% State Tax

Oregon has no sales tax but relies heavily on income tax. For high earners—and a lottery jackpot puts you there—the top bracket is in the 9.9%–10% range. So on a $60 million lump sum, state tax alone is about $6 million. That's among the highest state rates on lottery winnings in the U.S. Only a handful of states (e.g. New York 10.9%, New Jersey 10.75%) are in the same league. If you're used to hearing that neighboring Washington has no income tax, the contrast is stark: the same $60M win would cost $0 state tax in Washington and $6M in Oregon.

Assume cash value $60M (e.g. ~$100M advertised jackpot at 60%). Federal at 37%: $22.2M. Oregon at 10%: $6M. Total tax ≈ $28.2M; take-home ≈ $31.8M. The lottery withholds 24% federally ($14.4M), so you receive less up front and still owe the federal gap (about $7.8M) at filing. Oregon will also withhold or collect its 10% at or around payout. The main surprise for many winners is the size of the federal gap—plan for it so you're not short in April.

Oregon's 10% makes it an outlier in the region. Washington has no state income tax—so 0% on lottery winnings. California doesn't tax lottery winnings at the state level (0%). Nevada: 0%. So a winner in Portland pays $6M state tax on a $60M lump sum while a winner in Seattle or Los Angeles pays $0 state tax on the same prize. That difference is a big reason some people think about residency and where to claim; if you're an Oregon resident when you win, you owe Oregon tax on that income regardless of where you later move.

At payout, the lottery withholds 24% for the IRS. Oregon will take its share (typically 10% or the applicable rate) for state tax. So a large check is already reduced by federal and state withholding. The catch: 24% is not your final federal rate. If you're in the top bracket, you owe 37%, so 13% of the prize can still be due at filing. On $60M that's about $7.8M. Setting aside that amount—or making estimated payments—avoids underpayment penalties and last-minute scrambles.

Oregon taxes the full prize either way at up to 10%. The choice matters mainly for federal tax. A lump sum hits in one year (often 37% on the whole amount). An annuity spreads payments over 30 years, which can keep more of each year's payment in lower federal brackets and reduce the total federal bite. State side, you'll pay 10% on each year's payment with an annuity. A CPA can run both scenarios for your situation.

The Oregon Lottery has been funding state programs since 1985. A significant portion of net revenue goes to education, state parks, and economic development. The 10% you pay in state income tax on winnings is part of Oregon's general revenue structure—same as tax on wages or investments. That doesn't change your obligation, but it explains why the state treats lottery winnings as ordinary income.

With a combined rate pushing 47% on a large win, every planning step counts. Don't claim before talking to a tax attorney and a CPA. Use this calculator to see your approximate total tax and the federal gap. If you take the lump sum, plan to pay the extra federal tax at filing and consider estimated payments. Decide whether to claim as an individual or through an entity (if allowed by Oregon Lottery rules). Residency is key: if you're an Oregon resident when you win, you owe Oregon tax on that prize even if you move later.
