The Tax Cuts and Jobs Act (TCJA) that went into effect January 1, 2018 included a provision that limited the amount of state and local taxes (SALT) that are deductible for Federal tax purposes to $10,000 per year (previously uncapped). The SALT limit disproportionately impacted middle-to-high income residents of high-tax states that pay more than the new $10,000 limit.
