What regulations govern the practice of tax professionals before the IRS?

Circular 230 is the set of regulations specifically governing the practice of tax professionals before the IRS. It establishes the standards of conduct and responsibilities for tax practitioners, including attorneys, certified public accountants (CPAs), and enrolled agents. This regulation covers various aspects, such as ethical behavior, due diligence, and the penalties for misconduct, thus providing a guideline for professionals to follow when representing clients in tax matters before the IRS.

The other options, while related to tax practice, do not specifically embody the regulations that govern tax professionals in the same capacity as Circular 230. The Tax Code lays out the laws concerning taxation but does not focus on the conduct of tax practitioners. IRS Guidelines provide procedural information and directives but do not serve as governing regulations for professional behavior. Professional Ethics Regulations may pertain to ethical standards in the broader sense but are not tailored specifically for tax professionals under IRS jurisdiction like Circular 230.
