A Pennsylvania lottery winnings tax calculator has to account for two certain layers and one that depends on where you live: 24% federal withholding and 3.07% Pennsylvania withholding come off the top of any prize over $5,000, and Philadelphia residents owe another 3.74% on the back end. The combined bite usually lands between 35% and 40% of the prize, but the withheld amount rarely equals what you actually owe. The gap between withholding and final tax is where most winners get surprised.
What Comes Off the Top on Claim Day
When the net proceeds of your prize exceed $5,000, the Pennsylvania Lottery withholds 24% for federal income tax and 3.07% for state income tax before you leave with a check.1Internal Revenue Service. Instructions for Forms W-2G and 5754 (01/2026)2Pennsylvania Department of Revenue. Lottery Winnings On a $1,000,000 prize, that means the lottery keeps $240,000 for the IRS and $30,700 for Pennsylvania, and you walk out with $729,300.
Treat that number as a deposit toward your real tax bill, not your take-home. The 24% federal figure is a flat withholding rate that the IRS applies to gambling payouts; your actual federal liability runs through graduated brackets that almost always produce a larger number for a big prize.
Why the Federal Bill Is Bigger Than 24%
The IRS taxes lottery winnings as ordinary income, so the prize stacks on top of everything else you earned that year and gets sliced through the regular brackets. For 2026, a single filer’s brackets look like this:3Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026
- 10% on the first $12,400
- 12% from $12,401 to $50,400
- 22% from $50,401 to $105,700
- 24% from $105,701 to $201,775
- 32% from $201,776 to $256,225
- 35% from $256,226 to $640,600
- 37% on anything above $640,600
Married couples filing jointly get wider brackets, with the 37% rate not starting until $768,700, which means a joint filer owes somewhat less federal tax on the same prize than a single filer.3Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026
A common mistake is to assume the top rate applies to the whole prize. It doesn’t. Only the portion of your total taxable income above the 37% threshold is taxed at 37%. Everything below moves through the lower rates in order. That’s why the effective federal rate on a seven-figure prize usually runs in the low 30s, not 37%.
Pennsylvania’s Flat 3.07% Tax
Pennsylvania taxes lottery winnings at the same flat 3.07% it applies to all personal income.4Pennsylvania Department of Revenue. Personal Income Tax Multiply your winnings by 0.0307 and you have the state number. No brackets, no phase-outs.
You still have to report the full prize on your PA-40 return using Schedule T, the state’s form for gambling and lottery income.5Pennsylvania Department of Revenue. Instructions for PA-40 Schedule T – Gambling and Lottery Winnings Skipping Schedule T can generate a notice from the Department of Revenue even when the right amount was withheld.
Philadelphia Adds a Third Layer
If you live in Philadelphia, the city’s School Income Tax applies to cash lottery winnings from the Pennsylvania Lottery.6City of Philadelphia. The Lottery: Winning Numbers for You and the School District The current rate is 3.74%.7City of Philadelphia. Philly Extends Deadline for Relief Program, Announces Tax Cuts Nothing gets withheld for SIT at claim, so a Philadelphia resident who wins $1,000,000 owes roughly $37,400 more when the SIT return is filed by April 15.
Winners elsewhere in Pennsylvania don’t face a local tax on lottery income. The local earned income tax that most municipalities levy does not reach lottery winnings.
Working the Numbers on a $1,000,000 Prize
Here is what a single filer in Pennsylvania, outside Philadelphia, with no other significant income for the year, actually keeps from a $1,000,000 lump sum.
Withheld at Claim
- Federal, 24%: $240,000
- Pennsylvania, 3.07%: $30,700
- Check in hand: $729,300
Federal Tax at Filing
Subtract the 2026 standard deduction of $16,100 and taxable income is $983,900.3Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026 Through the brackets:
- 10% on $12,400: $1,240
- 12% on $38,000: $4,560
- 22% on $55,300: $12,166
- 24% on $96,075: $23,058
- 32% on $54,450: $17,424
- 35% on $384,375: $134,531
- 37% on $343,300: $127,021
Total federal tax comes to about $320,000. The lottery already withheld $240,000, so roughly $80,000 more is due at filing. The effective federal rate on this prize is about 32%, not 37%.
Final Take-Home
- Federal tax: ~$320,000
- Pennsylvania tax: $30,700
- Net: approximately $649,300
A married couple filing jointly on the same prize would owe somewhat less federal tax because the wider joint brackets hold more of the income at 35% and below. A Philadelphia resident subtracts another ~$37,400 for SIT, dropping the net closer to $612,000.
Lump Sum Versus Annuity
The payout choice changes the calculation more than any deduction can. A lump sum counts the entire cash value as income in one year, which pushes a big winner deep into the 37% bracket immediately. The advertised cash value is typically 40% to 60% below the headline jackpot, but even that reduced figure creates a very large one-year tax event.
An annuity spreads the payout across roughly 30 annual installments for Powerball and Mega Millions. Each installment gets taxed at whatever rates apply in that year, and because each payment is smaller, more of it falls into the lower brackets. A $300 million jackpot paid as an annuity produces annual payments around $10 million; each payment still tops out at 37%, but far more of the lower-bracket capacity gets used than in a single-year lump sum.
The trade-off is control and rate risk. Lump sum winners can invest the after-tax proceeds; annuity winners are locked into a payment schedule and exposed to whatever future legislatures do to tax rates over 30 years.
Deducting the Cost of Your Wagers
Federal and Pennsylvania rules on wager costs are not the same, so plan for them separately.
On the federal side, gambling losses are deductible only if you itemize on Schedule A, and the deduction can never exceed your winnings for the year.8Internal Revenue Service. Topic No. 419, Gambling Income and Losses For most winners, the standard deduction beats itemizing, so this helps mainly people who already have substantial documented gambling losses from the same tax year.
Pennsylvania is friendlier here. On Schedule T, you can subtract the cost of your wagers from your winnings. For Pennsylvania Lottery tickets bought on or after January 1, 2016, the ticket cost counts, and you can also deduct tickets purchased in other states or for other lotteries in the same year. Other gambling-related expenses like travel, meals, and entry fees do not qualify.9Pennsylvania Department of Revenue. Gambling and Lottery Winnings Keep records for every cost you claim.
Making an Estimated Payment So You Don’t Get Penalized
Because 24% withholding almost never covers a large winner’s federal bill, the IRS can charge an underpayment penalty at filing. You avoid it by paying, during the year, at least 90% of what you’ll owe for the current year, or at least 110% of the prior year’s tax if your adjusted gross income tops $150,000.10Internal Revenue Service. Underpayment of Estimated Tax by Individuals Penalty
The clean fix is to send an estimated payment on Form 1040-ES in the same quarter you claim the prize.11Internal Revenue Service. About Form 1040-ES, Estimated Tax for Individuals Run the bracket math on your total expected income, subtract what the lottery already withheld, and pay the difference. Waiting until April on a five- or six-figure shortfall is how winners end up paying penalties on top of tax.
Inputs You Need to Run Your Own Numbers
Before you plug figures into any calculator, pull these together:
- Your Form W-2G from the lottery, showing gross winnings and the exact federal and state amounts withheld.12Internal Revenue Service. About Form W-2G, Certain Gambling Winnings
- All your other income for the year. A winner who already earned $200,000 from a job starts higher in the brackets than someone with no other income.
- Your filing status. Single, married filing jointly, and head of household each have different bracket widths and standard deductions.
- Last year’s tax return, both for a baseline of recurring items and to compute the 110% safe harbor for estimated payments.
- Records of any wager costs you plan to deduct on the federal or Pennsylvania return.
Whether you live in Philadelphia is the other switch. Adding 3.74% for SIT, or leaving it out, is often the difference between a calculator that matches your April return and one that doesn’t.
