The Senate passed the final version of the bill introduced as the Tax Cuts and Jobs Act (TCJA) in the early hours of December 20, with the House of Representatives voting again the same day to pass the reconciled tax reform bill. President Trump signed the tax reform bill into law December 22, bringing home a major campaign promise. Due to a violation of Senate procedural rules, the bill’s name reverted to the more ungainly title, "To provide for reconciliation pursuant to titles II and V of the concurrent resolution on the budget for fiscal year 2018." We will refer to it merely as the tax reform bill, for ease of reference. As passed, the bill includes elements of both the House version and the Senate version of the tax reform bill.
