Repealing the cap would decrease tax liabilities for 13.1 million people, the report – released on Monday – noted.
“Approximately 99 percent of the decrease in tax liability accrues to taxpayers with $100,000 or more of economic income,” researchers wrote.
Those with incomes of more than $1 million would see tax liabilities decrease by $40.4 billion. People with incomes between $500,000 and $1 million would see liabilities decline by $14.4 billion, while those earning between $200,000 and $500,000 would experience an $18.2 billion decline.
Overall tax liabilities would decrease by $77.4 billion, the group found.
The Tax Cuts and Jobs Act introduced a number of reforms, including the notorious $10,000 cap on state and local tax deductions.
Democratic lawmakers in high-tax states have repeatedly pushed back on the cap, which is detrimental to their residents. The $10,000 cap is well below the average amounts claimed by individuals in states like New York, California and New Jersey. The average deduction claimed in California, for example, is $22,000, according to Kevin de Leon, a Democratic member of the California state senate.
A handful of states have even sued over the portion of the tax law. The U.S. recently moved to have the suit dismissed.

The strategy involved allowing taxpayers to make charitable contributions to an established state fund in order to earn a credit.
