Final answer:
Federal tax law is controlled by all three branches of the Federal government: Legislative, Executive, and Judicial. The correct answer is 2).
Step-by-step explanation:
Federal tax law is controlled by the Legislative, Executive, and Judicial branches of the Federal government. The creation and enactment of tax laws primarily fall under the purview of the Legislative branch, as only Congress has the authority to create laws, a power clearly articulated in Article 1 of the U.S. Constitution.
The Executive branch, under the leadership of the President, is responsible for implementing and executing these laws, which includes the collection of taxes. Finally, the Judicial branch plays a role in interpreting tax laws and resolving disputes related to them.
Thus, these three branches work in a system of checks and balances to ensure the fair administration of federal tax laws.
