What a total bunch of brain-dead nonsense. If you're paying more than $10K in state and local taxes, then you are in the top 10% of income earners and you live in a fairly expensive house. The "friend" who said that "Trump raised his property taxes by $4K" is both idiotic and very well off.
I live in Virginia. In order to pay more than $10K in state and local taxes, you have to make at least $120K per year *and* live in a house tax-appraised at over $330K. In order to pay substantially more--$3K or more--than $10K per year in state and local taxes, you have to make at least $180K per year and live in a house tax-appraised at over $500K.
And if you make $180K per year, your federal income tax burden will be cut by 3 percentage points for your first taxable $38K (single)/$77K (married), cut by another 3 percentage points for your taxable income between $38K-$82K (single)/$77K-$165K, and cut by 4 percentage points for your taxable income between $82-$157 (single)/$165-$315 (married).
So maybe your liberal friend should start lobbying his state and county governments to reduce their tax rates instead of expecting taxpayers in low-tax states to subsidize his state and local taxes that exceed $10K.
It depends on the location. In Los Angles, a median priced 3 bedroom house and a $70,000 taxable income would create a state tax in access of $10,000. This provision of the tax bill is designed to punish blue states since most blue states have higher property values, income, and taxes than red states. It's just party of the Trump plan to further divide the country.
Yep, and it was Obama’s agenda to divide America.

Don’t you get tired of all the nonsense?
I live in a blue state, my home is worth $400,000, there is no state income tax, most people in this state would need a close to a million dollar home to burn up the $10,000. Maybe Trump secretly likes my blue state, hmmmm....
Texas a $500,000 home would burn the $10,000 tax exempt limit. Why does Trump hate Texas?
And Florida, over a million dollar home and it wouldn’t hit the $10,000 exemption and that is a toss up state!
You could make up some wild conspiracy theories, have at!
What is funny is I find you one of the more reasonable people on this board then you come up with this nonsense.
