It’s a shift from the U.S. president’s first term, and is driving a fresh wedge within his Republican Party.

For as long as Americans have paid federal income taxes, they’ve been able to subtract some of what they pay to their state and local governments from their taxable income. This federal deduction for state and local taxes — the SALT deduction, for short — has a big influence on how the tax burden is divided. It tends to help taxpayers in wealthier, more urban states, where sales taxes are higher and real estate costs more.

The White House needs nearly every Republican to vote for the bill, but two distinct factions have their doubts.
