Final answer:
Tax law changes in the House of Representatives are primarily considered by the Ways and Means Committee, which is a standing committee responsible for initiating tax-related legislation.
Step-by-step explanation:
In the House of Representatives, tax law changes are primarily considered by the Ways and Means Committee. This is one of the standing committees, which are permanent and have jurisdiction over specific areas, such as tax law. This committee is significant in the legislative process because it is where the deliberation and initial crafting of tax-related bills occur. The Constitution stipulates that all bills for raising revenue must originate in the House, with the Ways and Means Committee playing a central role in their development before they move on to the Senate or other stages of the legislative process.
