Officials from New York, New Jersey and other states are seeking to appeal a September federal court decision that upheld the U.S. government’s new cap on how much taxpayers can deduct in state and local taxes, which was enacted as part of the country’s major tax overhaul nearly two years ago. The new filing comes almost two months after a federal judge, in September, upheld that part of the law, saying it was within the authority of Congress to establish the cap.

The SALT cap, approved by Congress as part of the Tax Cuts and Jobs Act of 2017, capped the amount taxpayers can deduct in state and local taxes, or SALT, at $10,000. Federal law did not previously place a limit on those deductions.
