From www.accountingtoday.com: The Treasury Department and the IRS have proposed significant amendments to Circular 230 that would ban contingency fees for tax return preparation and update provisions related to registered tax return preparers.

The revisions also require tax practitioners to maintain technological competency, establish data security policies, and clarify the jurisdiction of the IRS Office of Professional Responsibility over practitioners.

These changes reflect the latest legal developments and aim to ensure ethical standards within the practice before the IRS, but may face opposition from tax professionals regarding the contingency fee ban.
