The House Ways and Means Committee plays a crucial role in considering and shaping proposals related to tax laws and policies in the United States. Specifically, the committee has jurisdiction over all taxation, tariffs, and revenue-raising measures, and any bill related to these issues must pass through the committee before it can be considered by the full House of Representatives.
When the President proposes changes in tax laws, these proposals are typically introduced in the form of legislation by members of Congress, and they are first considered by the relevant committees. The Ways and Means Committee has the authority to hold hearings, conduct investigations, and propose amendments to any tax-related legislation. The committee also has the power to block any legislation it disagrees with or make changes to the legislation before it goes to a vote.
In addition, the committee has oversight over the Internal Revenue Service (IRS) and the Department of the Treasury, which are responsible for administering and enforcing tax laws in the US. This gives the committee an additional level of control over the implementation and enforcement of tax laws.
Overall, the House Ways and Means Committee plays a significant role in shaping and controlling tax policy in the United States, and any presidential request for changes in tax laws would need to go through the committee's review and approval process before becoming law.
