Trump’s tax bill would dramatically cut the amount of food and drug makers can deduct from their taxable income.
The changes would effectively eliminate many of the deduction breaks that have helped millions of Americans.
A new study published in the journal Public Interest Research found that the GOP plan would reduce the average deduction amount by about $10,000 for a family of four.
For the richest Americans, the average family would get about $11,400 less in their taxes under the new law, according to the study, which examined the impact of the tax legislation.
The researchers also found that nearly half of the poorest households would see their tax bill increase under the tax bill.
The average household would pay $3,000 less in taxes under this new tax plan.
Under the Republican tax plan, nearly 2 million Americans would lose their deduction for state and local taxes.
Under the current law, that amount is only $3.5 million.
The Trump administration has said the bill would reduce taxes for the average taxpayer.
But the Tax Policy Center, a nonpartisan nonpartisan think tank, has estimated that the plan would only provide about $1,500 to $4,500 in tax cuts to the wealthiest Americans.
The nonpartisan Tax Policy Foundation also said the new plan would decrease federal revenues by $2 trillion over the next decade.
