Final answer:
For 2019, the dollar limitation for the State and Local Tax deduction was $10,000. This limit was set by the Tax Cuts and Jobs Act of 2017 and affects property, income, and sales taxes.
Step-by-step explanation:
The dollar limitation for the State and Local Tax (SALT) deduction in 2019 was $10,000. This limit applies to the combined total of state and local property taxes, and either income or sales taxes that can be itemized for deductions on a federal tax return. The Tax Cuts and Jobs Act (TCJA), which was passed in 2017, imposed this limit starting in the 2018 tax year and it remains in place for subsequent tax years unless legislative changes are made.
