On the other hand, the SALT deduction incentivizes higher state and local spending and doesn’t have the great distributional implications, as my colleague Alex Brill carefully explains here. I could probably go either way on this one.
The SALT deduction is the largest itemized deduction and one of the largest tax expenditures in the entire tax code. I estimate that its repeal would raise $1.4 trillion in new revenue over a decade. In the piece for The Hill, I calculated how to “recycle” that $1.4 trillion in a distributionally neutral manner by lowering tax rates and increasing the standard deduction.
