Conformity

FDDEI deductions should be repealed for policy reasons alone as they do not serve a legitimate purpose at the state level.

Including NCTI in state corporate tax law is an effective way to neutralize much of the tax avoidance that occurs when multinational companies artificially shift their profits into overseas tax havens.

The results are a mixed bag, with some states enacting promising policies that will improve tax equity and others going in the opposite direction.

Federal lawmakers passed a bill along party lines that would force the District of Columbia to override the decision of local elected officials and implement all of the costly and inequitable federal tax cuts passed under the “One Big Beautiful Bill Act” (OBBBA).

They should take steps to protect and boost their own revenues. And they should take a second look at their own tax cuts.

This provision in last summer’s tax law could actually make budget-balancing a little bit easier for states if they follow suit.

From Congressional discussions over the so-called "One Big Beautiful Bill Act" to debates on property taxes, ITEP kept busy this year analyzing tax proposals and showing Americans across the country how tax decisions affect them.

The new tax law enacted last month found a temporary compromise on the level of the cap, boosting it to $40,000 through 2029, but failed to fix a loophole that allows some rich taxpayers with good accountants to completely avoid the cap

While a federal SALT cap is hotly debated, capping deductibility at $10,000 was an unambiguously good idea at the state level.
