Tax Standards

    Statements on Standards for Tax Services Overview 

    The AICPA’s Statements on Standards for Tax Services (SSTSs) are enforceable tax practice standards for members of the AICPA.  The SSTSs apply to all members regardless of the jurisdictions in which they practice and the types of taxes with respect to which they are providing services.  The original SSTSs, adopted in 2000, were revised in 2009, effective January 1, 2010. See below for links to the current and the former SSTSs.
