The WSOP 2026 schedule just dropped, and poker players across Canada are already marking their calendars and booking their flights to Las Vegas. Whether you are eyeing the Main Event or grinding the daily deepstacks, there is no feeling quite like the electric atmosphere of a summer in Sin City.
But as you prep your ranges and study your GTO charts, there is one opponent you should not overlook: the Internal Revenue Service (IRS). For many Canadians, the worst part of a WSOP cash is not the variance at the table. It is the 30% gambling tax the casino withholds at the payout cage before you ever leave the building.
At Casino Tax Refund, we understand that frustration because we are poker players, too. That is why we have put together this guide on WSOP gambling tax preparation for Canadians to ensure you are ready before you ever set foot on the plane. For the full breakdown of the recovery process, see our step-by-step guide to recovering your casino withholding.
What Happens When a Canadian Cashes at the WSOP
When a Canadian resident hits a qualifying payout at the WSOP, the casino may withhold 30 percent of the winnings and issue Form 1042-S. The withheld funds are sent directly to the Internal Revenue Service.
Withholding applies when net tournament winnings exceed $5,000 (gross payout minus the buy-in). This is not discretionary. It is a federal requirement applied to non-resident players under U.S. tax law.
If you want a full explanation of why casinos withhold 30 percent from Canadians and how the recovery process works, we cover that in detail in our guide to understanding the 30% withholding.
The sections below cover what is structurally different about 2026 and the specific steps you should take before boarding your flight.
The New 90% Loss Rule: Why WSOP 2026 Is Different
The 2026 series is the first full WSOP under the new 90 percent gambling loss limitation. Beginning with the 2026 tax year, documented gambling losses can only offset 90 percent of gambling winnings.
This change may sound technical, but it has real implications for tournament grinders.
Consider a typical WSOP summer:
Dozens of tournament entries
Multiple re-entries
Side cash sessions
A mix of small cashes and possibly one deeper run
Under prior rules, if your documented U.S. losses matched your winnings, your taxable position could often be reduced to zero. Under the 2026 framework, even a break-even year may leave 10 percent of winnings exposed to tax.
You win $50,000 and document $50,000 in losses. Previously, you could offset the full amount. Under the 2026 rule, only $45,000 of those losses apply, leaving $5,000 taxable at 30%. That is $1,500 you cannot recover.
For high-volume players, this shifts tax considerations from a clerical issue to a planning issue. Volume magnifies the effect of structural rules.
WSOP Gambling Tax Scenarios That Deserve Attention
General gambling tax advice rarely accounts for how the WSOP actually works. Series play introduces complexity that single-event trips do not.
Multiple Cashes Across Different Events
A productive WSOP summer can generate several payouts, each accompanied by its own documentation. Managing multiple 1042-S forms across different casinos or properties requires organization. Losing or misplacing even one form can delay reconciliation later.
For example, if you cash in a WSOP event at the Horseshoe and a Wynn Summer Classic side event the same week, each property issues its own 1042-S independently. You must collect both.
Re-Entries and True Economic Results
Modern WSOP structures encourage re-entries. From a poker perspective, that is standard. From a documentation perspective, it requires discipline.
If you enter a $1,500 event four times and cash once, your true cost basis is $6,000, not $1,500. Your economic reality differs from what a single payout slip suggests. Accurate tracking ensures that your true net position is reflected properly when filing.
Selling Action and Backing Agreements
Many Canadian players sell pieces of themselves during the WSOP. The IRS, however, sees the payout issued in your name, not your staking arrangement.
If you only retain a percentage of your action, clean documentation of ownership percentages and distributions becomes important. Without it, your reporting may not reflect your actual economic interest.
Before the series, create a written record of each staking arrangement that includes the percentage sold, the backer's name, and the terms of distribution.
Playing Cash and Other Games Between Events
A WSOP summer rarely consists only of bracelet events. Players often:
Play cash games at nearby casinos
Participate in other summer series
Place sports bets
Certain table games like blackjack, baccarat, and roulette are generally exempt from withholding for Canadians. If a casino accidentally withholds on one of these games during a side session, flag it — that strengthens your refund case further.
All U.S.-sourced gambling activity within the same tax year can affect your overall position. Treating each event in isolation creates unnecessary risk.
Your Pre-Flight WSOP Tax Checklist
WSOP preparation should extend beyond strategy and bankroll management. Before departing for Las Vegas, Canadian players should address several practical considerations.
Check Whether You Have an Active ITIN
To reconcile withheld funds through a U.S. non-resident return, you must have an active Individual Taxpayer Identification Number. If you do not have one, or if yours has expired, that issue will need to be resolved during the filing process.
We explain the ITIN process in detail in our dedicated guide to applying for an ITIN from Canada.
ITIN applications typically take 6 to 11 weeks. Confirming your status before the series reduces uncertainty if you hit a significant score.
Establish a U.S.-Only Tracking System
Before you leave Canada, set up a clean and simple tracking framework. At minimum, you should log:
Event name and buy-in
Re-entries
Cash sessions
Sports wagers
Payout amounts
Dates and locations
Maintaining contemporaneous records is significantly more reliable than reconstructing activity months later.
A basic spreadsheet is sufficient. The key is consistency.
Collect Your Form 1042-S at the Cage Before You Leave Vegas
Every time a casino withholds tax, they produce a Form 1042-S. Do not leave the property without collecting your copy. If you cash in multiple events across different venues, you will need a 1042-S from each one. Misplacing a form adds time to your claim. Casino Tax Refund can help obtain duplicates, but collecting them on the spot is always faster.
Request Win/Loss Statements at Every Casino's Rewards Desk
Before you fly home, visit the rewards desk at each property where you played. A printed Win/Loss statement is powerful secondary evidence that corroborates your session logs and strengthens your filing.
Plan for Processing Timelines
If tax is withheld during the WSOP, reconciliation does not happen immediately. Non-resident filings via Form 1040-NR are typically processed on paper and can take 6 to 12 months.
If you anticipate relying on recovered funds for future bankroll seasons, plan accordingly.
If You Brick the Series
Even in a losing year, your documented losses have real dollar value. Discipline in losing years protects you just as much as discipline in winning years.
If you lose over the course of the summer, proper documentation still matters. U.S.-sourced losses form part of your overall gambling record for the tax year.
Under the new 90 percent rule, every dollar of documented loss is more valuable than before. The deduction cap means you need thorough records to maximize what you can offset.
Treat recordkeeping as part of your professional structure, not as a reaction to success. If you had tax withheld in a losing year, your documented losses may support a full recovery. Reach out to see if you qualify.
A Final Word for Canadians Playing WSOP 2026
The 2026 WSOP will be competitive. Fields will be large. Variance will be high. The new 90 percent rule adds another structural variable to consider.
You cannot control outcomes at the table.
You can control your structure.
If you are travelling from Canada to play this summer, treat gambling tax preparation as part of your overall WSOP strategy. Casino Tax Refund handles the entire filing process, from identity verification to IRS submission, so you can focus on the tournament. The players who approach the series with discipline off the felt give themselves an edge before the cards are even in the air.
Frequently Asked Questions About WSOP Taxes for Canadians
Are poker winnings taxable in Canada?
Canada does not tax gambling winnings for recreational players. However, when you win at the WSOP in Las Vegas, the IRS treats those winnings as U.S.-sourced income. A 30% withholding tax applies to net tournament winnings of $5,000 or more, regardless of how Canada handles it at home. The good news is that as a Canadian, you can file a U.S. non-resident return to recover most or all of that withheld amount.
How much does the IRS actually withhold from a WSOP cash?
The IRS requires casinos to withhold 30% on net tournament winnings of $5,000 or more. Net winnings are calculated as your gross payout minus the buy-in. For example, if you pay a $1,500 buy-in and win $15,000, your net is $13,500 and the casino withholds $4,050 on the spot. You will receive a Form 1042-S documenting this withholding, which you will need when filing for a refund.
Do I need an ITIN before I fly to Vegas for the WSOP?
You do not need an ITIN at the payout cage. The casino will withhold the tax regardless of whether you have one. However, you must have an ITIN to file Form 1040-NR and claim your refund after the trip. ITIN applications through the IRS typically take 6 to 11 weeks to process, so applying before you travel ensures you are ready to file as soon as your Form 1042-S arrives. The refund itself, filed separately, typically takes 6 to 12 months.
Can I deduct my WSOP buy-ins and other tournament entries as losses?
Yes. As a Canadian filing a U.S. non-resident tax return, you can deduct your documented U.S.-sourced gambling losses against your winnings under the Canada-U.S. Tax Treaty. This includes tournament buy-ins, re-entries, and satellite entries played in the United States. Under the One Big Beautiful Bill Act, signed into law on July 4, 2025, gambling loss deductions are capped at 90% of winnings starting with the 2026 tax year. Detailed, contemporaneous records are now more important than ever.
How long does it take to get a U.S. gambling tax refund as a Canadian?
Non-resident tax refund claims filed via Form 1040-NR are processed on paper by the IRS. Most Canadian filers receive their refund within 6 to 12 months of submission. The timeline depends on IRS processing volume, the completeness of your documentation, and whether your ITIN is already active. You have up to three years from the date of the winnings to file your claim, so there is no need to rush, but earlier filings tend to process faster.
Is it worth filing for a refund on a small WSOP cash?
It depends on the amount withheld and your total documented U.S. gambling losses for the year. Filing Form 1040-NR involves professional preparation fees, so for very small withholdings the cost may outweigh the refund. As a general rule, if the IRS withheld $500 or more, a recovery filing is likely worthwhile. Casino Tax Refund can help you assess your specific situation before you commit to filing.
Do I have to report U.S. gambling winnings on my Canadian tax return?
For recreational gamblers, Canada does not require you to report gambling winnings as taxable income. However, if you are considered a professional gambler by the CRA, your worldwide gambling income may be taxable in Canada. The U.S. withholding is a separate matter handled through the IRS. If you successfully recover your withheld taxes through a U.S. filing, the refund itself is not taxable income in Canada for recreational players.
What is the new 90% gambling loss rule for 2026?
Under the One Big Beautiful Bill Act, signed into law on July 4, 2025, gambling loss deductions are capped at 90% of winnings starting with the 2026 tax year. This means that even if your documented U.S. losses equal your winnings, 10% of those winnings remain taxable. For example, if you win $50,000 and document $50,000 in losses, only $45,000 of losses apply, leaving $5,000 taxable at 30%. This makes thorough recordkeeping more important than ever for Canadian players at the WSOP.
