As Senate Republicans release key details of President Donald Trump’s spending package, some provisions, including the federal deduction for state and local taxes, known as SALT, remain in limbo.

Enacted via the Tax Cuts and Jobs Act, or TCJA, of 2017, there’s currently a $10,000 limit on the SALT deduction through 2025. Before 2018, the tax break — including state and local income and property taxes — was unlimited for filers who itemized deductions. But the so-called alternative minimum tax reduced the benefit for some higher earners.

The Senate Finance Committee’s proposed text released on Monday includes a $10,000 SALT deduction cap, which is expected to change during Senate-House negotiations on the spending package. That limit is down from the $40,000 cap approved by House Republicans in May.
