That’s not true for US Resident players who sign heavy bonus structured contracts
In fact that was the only reason Huberdeau reupped so quickly in Cgy after Fla trade. Alberta has lowest provincial taxes + his deal is heavily bonus structured. So bonuses are not viewed as income in most US states (incl his home in Fort Lauderdale) and his Cdn portion of taxes are at lowest taxation rate
It’s also why Tavares squabble with Revenue Canada right now about back taxes owed, is so important to Cdn teams. Tavares despite having US residency status, didn’t actually spend 6-months + 1-day in the US to meet residency requirements for US taxation per US / Canada tax treaty
It’s the Matthews effect, at $12M ($1M actual salary), even zero tax states would need to offer Stamkos upwards of $14M to match take home
