Final answer:
The Congressional Budget Office (CBO) analyzes budgetary implications and evaluates economic effects of policies but does not enforce tax laws, which is the job of the IRS and Treasury.
Step-by-step explanation:
The Congressional Budget Office (CBO) is responsible for several key functions, including analyzing budgetary implications of proposed legislation, evaluating the economic effects of different policies, and creating budget estimates to assist in policy analysis.
However, the CBO does not have the mandate to enforce tax laws; this responsibility lies with the Internal Revenue Service (IRS) and the Department of Treasury. The CBO is known for its attempts to remain non-partisan and provide objective analyses to assist Congress in making informed budgetary decisions.
