I’m guessing Trump already uses Mira Lago or some other Florida property as his official residence for tax purposes. Listening to how Rush describes it, every day Trump works in NYC, the State of New York STILL assesses an income tax but only a moron would declare New York their official residence and let that socialist state screw him in the ass on a daily basis.
If The President is still a resident of NY then he’d report all income, pay taxes to those states outside NY on that state’s income, then receive credits for taxes paid to those states.
To the extent a state like FL has no income tax, he’d get no credit and would pay the equivalent of NY tax on his Florida income.
His interest and dividends are all reported in the state of his resident, NY, regardless of where the bank, corporation etc are located or HQd
IOW, NY with its high rates gets the lion’s share.
