A sweeping tax package has passed the U.S. House and is now headed for the U.S. Senate.

But Senate procedural rules mean some provisions of the bill may have to be stripped, which will require the House to revote on Wednesday.

• Congress voting on GOP tax bill today
• Bill passed House, 227-203
  
• $1.5 trillion tax package

Senate Democrats say there are three provisions in the bill that violate Senate rules that will allow the chamber to vote with a simple majority. 

One of those provisions lets families use tax-advantaged 529 accounts for homeschooling expenses.

The bill represents the most sweeping rewrite of the nation’s tax laws in more than three decades. It's not known yet what the other two are.

Assuming those provisions are stripped from the final bill, the Senate is expected to vote Tuesday night or Wednesday morning. The House will then take the revote after.

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.

Every Republican Florida representative voted in favor of the bill, while every Democratis representative voted against it.

Overall the vote went largely along party lines, with all Democrats voting against the bill and 12 Republicans voting no. Those Republicans come from states like California and New York, where analysts say the average taxpayer will likely lose out because of a repeal of some deductions.

Heading to the Senate

The bill now goes to the Senate for an expected vote Tuesday evening.

Rubio tweeted that he became an "enthusiastic YES" after his demands for higher child tax credits were met.

Corker, however, is facing some harsh criticism for switching sides. He was originally a "no" vote because of projections that the plan could add a trillion dollars to the national debt.

However, soon after a tax deduction was added that could benefit his real estate investments, Corker said he was in favor of the bill. Now, people are calling him out on Twitter using #corkerkickback.

California Democratic Rep. Ted Lieu wrote that it "looks like straight up self-enrichment."

Florida Democratic Sen. Bill Nelson took the floor Monday night and spoke out against the bill.

"Under current law, corporations that send jobs overseas have to pay taxes on the money that they bring back into the U.S.," Nelson said, "But now what this new GOP tax bill says, is corporations that send jobs overseas can bring the money back to the U.S. tax-free."

However, with Rubio and Corker now on board, all Republicans in the Senate are in favor of the bill, which would allow it to pass. Two more holdout GOP senators — moderate Susan Collins of Maine and Mike Lee of Utah — came into the fold on Monday.

Now, the biggest reshaping of the U.S. tax code in three decades is on a clear path to passage and a presidential signing into law. It permanently slashes the tax rate for corporations from 35 percent to 21 percent and reduces levies on the wealthiest Americans, while making more modest tax reductions for most others. The tax cuts for individuals are temporary, expiring in 2026. It doubles the standard deduction used by about two-thirds of U.S. households, to $24,000 for married couples, also ending in eight years.

Those who itemize lose some deductions.

The legislation also repeals an important part of President Barack Obama’s health care law — the requirement that all Americans carry health insurance or face a penalty — as the GOP looks to unravel a law it failed to repeal and replace this past summer.
