NYSSCPA members who provide tax services to clients, including tax return preparation, and represent clients before the IRS and New York state, are subject to various rules from a variety of sources. These include the AICPA Code of Professional Conduct, which the NYSSCPA adopted as its own conduct code in May 2013; the AICPA Statements on Standards for Tax Practice; the New York State Board of Regents (NYS Accountancy Regulations); and Circular 230, which describes rules governing practice before the IRS for CPAs and other authorized practitioners, including attorneys and enrolled agents.
