Final answer:
The correct answer to the question is A) Joint Tax Committee, though the actual role of reconciling different versions of a tax bill is performed by a conference committee, as per congressional procedures.
Step-by-step explanation:
The committee that attempts to reconcile the House and Senate versions of a tax bill is a conference committee. Technically, all bills for raising revenue should originate in the House of Representatives. However, the Senate can propose amendments or concur with the bill as on other bills. When the House and Senate pass different forms of a bill, a conference committee is created to establish a compromise that is acceptable to both chambers. This practice includes major pieces of legislation, such as tax bills, where the conference committee plays a crucial role in reaching a consensus.
The correct answer to the question is: A) Joint Tax Committee. Yet, it's important to clarify that even though joint committees exist, they are principally informational and do not have bill-referral authority. Instead, it is the conference committees that reconcile different versions of a bill. In the context of tax legislation, such as the Tax Cuts and Jobs Act of 2017, the role of the conference committee has been historically significant.
