Congress has now approved the final version of the Tax Cuts and Jobs Act (H.R. 1) on a party-line vote (51-48 Senate, 224-201 House), sending the GOP tax overhaul to President Donald Trump to be signed into law. The approximately $1.5 trillion tax package includes substantial individual and business tax cuts, along with many other far-reaching changes to U.S. tax law, and represents fulfillment of a key campaign promise for Congressional Republicans and President Trump.

Final passage was not achieved without some last-minute surprises. Shortly after the House originally approved the legislation on December 19, the Senate parliamentarian determined that several provisions in the tax package would need to be stricken from the bill per the Senate's budget reconciliation rules unless they were supported by at least 60 votes. These provisions were ultimately removed from the final bill that the Senate approved on December 19, which meant that the House had to vote again on the final bill on December 20.
