IRS to tax up to $44M of Spain’s $50M World Cup prize

Spain lifted the World Cup trophy on July 19 after a 1-0 victory over Argentina in the 2026 final. The celebration lasted about as long as it took for US tax authorities to start doing math.

The IRS has claimed that a significant portion of Spain’s $50 million winner’s prize qualifies as US-sourced income, since the tournament was co-hosted on American soil. Some estimates peg the potential tax liability at up to $43.75 million, which would leave Spain’s federation with roughly $6.25 million from a $50 million check.

How the IRS math works

Under standard withholding rules, foreign entities earning US-sourced income face a 30% tax rate. Applied to the full $50 million, that would be roughly $15 million.

The effective tax burden could climb significantly higher depending on how many of Spain’s matches were played on US soil versus the other co-host nations, Canada and Mexico. The more games Spain played in the US, the larger the share of prize money the IRS can classify as domestically sourced. Some analyses have pegged the effective exposure at $43.75 million, suggesting the vast majority of Spain’s tournament path ran through American venues.

There is a US-Spain income tax treaty that could provide some relief. Treaty provisions can reduce withholding rates on certain types of income, and Spain’s federation could potentially claim credits or reduced rates under this bilateral agreement.

The bigger picture for international sports

The total prize pool for the 2026 World Cup exceeded $655 million. Only the winnings attributable to US-hosted matches face IRS scrutiny for foreign teams. Matches played in Canada and Mexico fall outside Washington’s tax jurisdiction.

Spain isn’t the only team affected. Every non-US team that played matches on American soil during the tournament faces some degree of tax exposure on their prize money. Argentina, as the runner-up, earned a smaller but still substantial prize, and would face similar proportional calculations. Even teams eliminated in earlier rounds that played group-stage matches in US cities could owe something.

What this means for global sports finance

The US-Spain tax treaty remains the most likely avenue for reducing the final damage. If Spain’s federation and its tax advisors can successfully invoke treaty provisions, the effective rate could drop meaningfully below the headline $43.75 million figure.
