SALT is an acronym. It's states for State And Local Taxes. You are limited to deducting a maximum of $10,000 for these taxes on your federal return. $5000 if you are married filing separate. SALT is the total of all local taxes paid to include state tax, property tax, and any other tax imposed by any taxing authority at the state level or below. These taxes, if you paid them, are already on your tax return if you actually entered them when prompted by the program.
