Democrats say three provisions in the Republican $1.5 trillion tax bill violate Senate rules and will likely be removed before that chamber votes on the measure.
The House approved the legislation Tuesday. But this means the House will have to vote again on the legislation once it’s been amended and approved by the Senate.
Senate passage was expected Tuesday night or early Wednesday. GOP House Majority Leader Kevin McCarthy’s office says the House would reconsider the bill Wednesday morning and send it to President Donald Trump for his signature.
Democrats said the Senate parliamentarian had found three items that violated Senate rules.
These included one provision that would let families use tax-advantaged 529 accounts for home-schooling expenses.
The problem was revealed by Vermont independent Sen. Bernie Sanders and Oregon Democrat Ron Wyden.
The House has passed the most sweeping rewrite of the nation's tax laws in more than three decades. The bill now goes to the Senate for an expected vote Tuesday evening.
The House approved the bill by a mostly party line vote of 227-203. The bill represents the first major legislative victory for President Donald Trump.
The $1.5 trillion package would provide steep tax cuts for businesses and the wealthy and more modest cuts for middle- and low-income families. The business tax cuts would take effect in January. Workers would start to see changes in the amount of taxes withheld from their paychecks in February.
The bill would nearly double the standard deduction used by most taxpayers, while those who itemize would lose some deductions.
