The highest-paid Denver Broncos players will owe California thousands in taxes after their Super Bowl win Sunday, thanks to the state’s big tariffs on an athlete’s income.

These fees — sometimes called ” jock taxes” — exist in most states that have professional sports and a state income tax specific to athletes. In California, they fall under the state’s “sports program.”

What’s owed in the Golden State is calculated by dividing an athlete’s days of work by their overall compensation to create a ratio. The ratio is then multiplied by the compensation to reach what is owed.

Signing and performance bonuses can be included in what is taxable.

California’s income tax rate is 13.3 percent, which is higher than other states.

Sean Packard, tax director of Octagon Financial Services in McLean, Va., says that will mean big payouts from the Carolina Panthers and Broncos.

“Their tax rate is so high and guys are spending seven days there rather than one or two,” Packard said of the Super Bowl as compared with regular-season games.

Packard, who wrote about the topic for Forbes, said this year’s Super Bowl players will have 206 duty days in 2016, including minicamps, training camps, practices, games and playoffs.

Using that duty day number, he estimates Panthers quarterback Cam Newton owes California about $87,800 for the Super Bowl.

Packard said he couldn’t calculate what is owed by Broncos quarterback Peyton Manning and linebacker Von Miller because their salaries — and if Manning will even play — are still up in the air for next season.

By his estimate, however, Manning had to pay some $47,000 to New Jersey for playing in the Super Bowl against Seattle.

Mark Goldstick, a certified public accountant who specializes in the jock taxes, said he feels Packard’s estimate of what Newton owes is high by about $60,000.

Goldstick, who is based in Scottsdale, Ariz., declined to talk about how he came up with his estimation because he says it would give away his proprietary secrets.
