On lottery winnings in Rhode Island, you will pay federal taxes up to 37% and state taxes up to 5.99%, with no local income taxes. Federal withholding is 24% on prizes over $5,000, while Rhode Island withholds 5.99% on prizes exceeding $2,500. Your actual tax liability depends on your total income, pushing you into progressive brackets for both federal (10%-37%) and state (3.75%-5.99%) taxes. Rhode Island treats lottery winnings as ordinary income, subject to these rates without any special exemptions. For a $1 million lump sum prize, expect about $240,000 federal withholding and $59,900 state withholding upfront, but final federal taxes could reach $370,000 if you're in the top bracket. This leaves you with roughly $530,100 after initial withholdings, though you might owe more or get a refund when filing. While this provides a general overview based on 2025 tax rates, consult a tax professional to calculate your exact liability.
