In the near past, regardless of the amount, state and local taxes were deductible for the full amount. With the new tax legislation just passed, the limit is $10,000. For many people, that probably doesn't mean anything, but in too many states, that means a pickpocket will now be exposed.
I don't think many people realized how much the federal government funded the sometimes expensive whims of states, and communities. Taxpayers that could, deducted state and local taxes. Those without the burden, didn't have the deduction. They paid more taxes, and were basically helping those with the excessive taxes from becoming completely pissed-off. With the new tax law, some might find the thousands they once deducted will now be a burden they might not be able to afford, and some states are scrambling for relief from what will soon come.
I feel sorry for those impacted by this legislation, but like a boss once said: "I can feel for you, but just can't reach you." The problem is not the new legislation; the problem is out of control political entities and their foolish spending habits. The focus should be on the state and local legislators. I have a feeling that focus will lead to some unkind actions by those so severely impacted by excessive taxes.
