The Prize That Could Come With A Surprise Of Its Own
Your Canadian friend just won a huge cash prize while visiting the US, and everyone was celebrating. Then someone mentioned taxes. Would a Canadian owe American taxes? The answer can get surprisingly complicated.
Canadians And Americans Play By Different Rules
Although the two countries are neighbors, they treat contest and lottery winnings very differently. That's why crossing the border can completely change the tax picture.
Canadians Usually Don't Pay Tax On Winnings
In Canada, lottery jackpots, sweepstakes prizes, casino winnings for casual gamblers, and most contest prizes are generally tax-free. If you win $1 million, you usually keep the entire $1 million.
The US Treats Winnings As Income
The United States generally considers lottery prizes, sweepstakes, game show winnings, casino jackpots, and many other prizes to be taxable income. Winning a large prize can significantly increase your tax bill.
That's A Big Difference
Imagine two people each win a $1 million prize. A Canadian winner may keep nearly all of it, while an American winner could owe hundreds of thousands of dollars in federal—and sometimes state—taxes.
So, What If A Canadian Wins In The US?
Now things become more interesting. Even though Canada normally doesn't tax lottery or contest winnings, the United States may still tax prizes won within its borders.
The IRS May Withhold Money Immediately
For many prizes paid to non-US residents, the payer may be required to withhold up to 30% before the winner even receives the money, depending on the type of prize and applicable tax rules or treaties.
Canada And The US Have A Tax Treaty
Fortunately, the Canada-US Tax Treaty can affect how some winnings are taxed and may allow certain Canadians to recover part of the tax or reduce double taxation in specific situations.
Not Every Prize Is Treated The Same
Lottery winnings, casino jackpots, television game shows, sweepstakes, and promotional contests don't all follow identical tax rules. The type of prize matters.
Professional Gambling Changes Things
Canada generally doesn't tax casual gambling winnings. However, someone who earns a living as a professional gambler may face very different tax treatment.
The IRS Wants Documentation
If tax is withheld in the United States, you'll usually receive tax forms documenting the prize and any withholding. Don't throw those papers away—they're important.
You May Need To File A US Tax Return
Some Canadian winners may need to file a US non-resident tax return to report the winnings or request a refund if too much tax was withheld.
State Taxes Can Also Apply
Federal tax isn't always the end of the story. Some US states also tax gambling or contest winnings, while others don't.
What About Americans Winning In Canada?
Here's where the situation flips. Canada may not tax the winnings—but the United States often still will.

Americans Pay Tax On Worldwide Income
US citizens and many US residents generally report worldwide income on their federal tax returns. That means a tax-free Canadian jackpot may still need to be reported to the IRS.
Winning In Canada Doesn't Always Mean Tax-Free
An American who wins a Canadian lottery might not owe Canadian tax, but they could still owe US federal income tax after returning home.

A Car Counts Too
Winning a new vehicle isn't just exciting—it may also create a tax bill in the United States. The IRS generally taxes the fair market value of many non-cash prizes.
Trips And Vacations Can Be Taxable
An all-expenses-paid vacation won in a contest can also be treated as taxable income for many American winners.
Canadians Usually Have Different Expectations
Many Canadians are surprised to learn that prize winnings are taxable in the United States because that's simply not how things work at home.
Don't Spend Everything Right Away
If you've won a major prize in another country, it may be wise to wait until you understand the tax consequences before making large purchases.
Currency Exchange Matters
When filing tax documents, exchange rates may also become important because prizes often need to be reported in the correct currency.
Large Jackpots Can Affect Other Finances
Major prizes may influence financial planning, investment decisions, estate planning, and eligibility for certain income-tested benefits.
Cross-Border Tax Experts Can Save Money
International tax rules become complicated quickly. Professional advice can sometimes prevent costly mistakes or identify refunds you didn't know were available.
Keep Every Piece Of Paper
Prize notifications, tax forms, receipts, and payment records may all become important if questions arise later.
The Biggest Mistake Winners Make
Many people assume the tax rules from their home country automatically apply everywhere. That's one of the easiest ways to end up with an unexpected tax bill.
So, Who Pays Tax?
Generally speaking, Canadians usually don't pay Canadian tax on contest or lottery winnings. However, if the prize is won in the United States, US tax rules may apply. Likewise, Americans who win prizes in Canada may still owe U.S. tax because the United States taxes its citizens on worldwide income.
The Border Doesn't Change Everything
Winning a life-changing prize should be exciting—not confusing. But when money crosses international borders, understanding the tax rules can be just as valuable as the prize itself.
