The IRS just got its own World Cup payday | Official Website of Louis Velazquez, entrepreneur, finance guy and tech innovator

Every windfall arrives with a second number attached, and almost nobody talks about the second one.

There is the amount you won. That is the figure that goes on the poster, in the headline, in the group chat. Then there is the amount you keep, which shows up quietly a few weeks later and rarely matches.

Most of us learn this in small doses. A bonus lands short of what the letter promised, and a freelance invoice clears with something already carved out of it.

Professional sports runs on the identical principle, just with more zeros and more borders. FIFA approved a record $727 million contribution in December, then raised the total again in April after European federations lobbied for travel help.

Spain beat Argentina 1-0 in extra time on July 19 at MetLife Stadium and collected the largest champion’s check in the tournament’s history. The World Cup winner earns $51 million, with second place taking $34 million, according to CNBC.

Then the Internal Revenue Service (IRS) got in line.

How the IRS sources a foreign team’s World Cup prize money

The rule at the center of this is not new and it is not a soccer rule. Money earned for work performed inside the United States is US source income, and foreign recipients owe US tax on it regardless of where they live or where the check is cut.

What made 2026 unusual is that the tournament straddled three countries, which meant somebody had to decide which slice of a prize belongs to which government.

The three tax agencies handled that in advance. Compensation for a participating member association should be allocated “based on the games played in a specific jurisdiction,” according to the Canada Revenue Agency, in a consensus reached with the IRS and Mexico’s Servicio de Administracion Tributaria.

The formula is deliberately plain. Multiply total earnings by matches played in a country, then divide by total matches played across all three hosts.

So I pulled Spain’s actual route and ran it through the formula rather than trusting the round numbers going around.

Atlanta on June 15 and June 21, the group draw with Cape Verde and the 4-0 win over Saudi Arabia, both inside the United States, according to Sky Sports.
Zapopan, Mexico on June 27, the 1-0 win over Uruguay, the only Spain match played outside American borders, according to Sky Sports.
Los Angeles and Dallas from July 2 through July 14, four consecutive knockout wins over Austria, Portugal, Belgium and France, all on US soil, according to FIFA.
East Rutherford, New Jersey on July 19, the final against Argentina, according to FIFA.

That is seven of eight matches in the United States, or 87.5% of Spain’s tournament.

Why the $43.75 million tax bill number is wrong

Apply the agreed formula and roughly $44.6 million of Spain’s $51 million prize gets sourced to the United States. Foreign entities and athletes face “30% federal withholding tax on the gross amount,” according to the Taxpayer Advocate Service, unless a lower treaty rate, a statutory exemption or a Central Withholding Agreement applies.

Thirty percent of $44.6 million is about $13.4 million.

That is the default withholding, not a confiscation.

More Taxes:

Here is where my analysis parts ways with most of what got published this week. The $43.75 million number in circulation is $50 million multiplied by seven-eighths.

That is the share of income allocated to the United States, not the tax on it. Somebody read an allocation figure as a bill and it traveled from there.

Headlines claiming Spain lost half its prize have the same problem. Withholding at 30% of the US-allocated portion is roughly a quarter of the total check, before any refund.

What the US-Spain tax treaty actually does here

Treaties get invoked in these stories as though they are an escape hatch. They are narrower than that.

Under the US-Spain convention, an athlete’s performance income is taxable where the performance happened once compensation exceeds “ten thousand United States dollars,” according to the treaty text published by the IRS. Every player on Spain’s roster cleared that threshold in a single knockout round.

The second paragraph of that same article matters more, and I have not seen it raised anywhere in this week’s coverage. When income from an athlete’s activity accrues to somebody other than the athlete, a federation, for instance, that income can still be taxed where the athlete performed.

It specifically overrides the business profits article. The Spanish federation cannot route around the bill by noting it has no US office.

State rules sit on top of all this. New Jersey does not recognize international tax treaties for state income tax purposes, KPMG’s Rob Fagan noted, as reported by Benzinga, which means the final itself carries a state layer no treaty softens.

What these World Cup tax rules mean for your own money

The useful part is what happens after the withholding.

That 30% is not a final tax. It is a deposit taken off the top before expenses, and the recipient files a return afterward to reconcile it.

Overpay and you claim it back. Athletes and federations do this every year.

The same structure governs far more ordinary situations. Income earned inside a jurisdiction is generally taxable by that jurisdiction, whether you are a Spanish midfielder in Atlanta, a consultant with a client in another state, or an American picking up contract work abroad.

The paperwork scales down. The logic does not.

Spain’s federation now decides how to split what remains among players, staff and grassroots programs. The players face individual determinations of their own, shaped by residency and endorsement structures.

The trophy goes home clean. The money goes home with paperwork, and a refund claim sits somewhere in the pile.

That gap between the poster number and the deposit number is the most durable feature of the whole tournament. It shows up again in 2030, when the hosting map changes and the arithmetic starts over.
