If there's an actual city income tax that is assessed on a paycheck for someone working in that city (whether they live there or not), there's no issue in including it. You had this silly idea of including property taxes and everything else (including sales taxes). I have no problem including city-level taxes assessed on the income of someone working in that city (regardless of where they live). All that is is an income tax.
An actual income tax is a far cry from taking ****ing property taxes into account.
You find it funny, but is it that far fetched? It's ultimately just the next step in the process, if you dont lack vision. Once we've made a level playing field for 'income tax' the argument will be "players are signing cheaper deals in X state/province because they dont have to pay sales tax/no property tax/no whatever tax, and its creating an unfair advantage because players get more take home pay because of that."
The point isnt that i think property taxes are impactful. The point is that there is absolutely no way to even the playing field on income taxes. A state like Florida collects a large amount of income because the roads are tolled. Isnt that an unfair advantage? At what point do the advantage become 'meaningless'?
All of this compllete ignores that the impact isnt nearly as large as people are making it out to be. Players play 41 games at home. They pay taxes in every other state when they play their. cut whatever advantage people are actually getting in half, and is it really as sizable as being suggested? Likely not. Here's a fun game too - once we equal out income taxes, is it fair that Toronto gets to play more games in FLorida (against the panthers and tampa), thus paying less in income tax to a team in the Metro, who doesnt get to play as many games in tax-shelter states?
Just so we're clear, that last sentence or two isnt entirely serious - but it just reiterates the point that people are always going to have advantages. Everyone wants to play the 'parity' game until it turns on them, then its not as much fun.
