The complexity of S corporation tax law creates a formidable challenge for the tax practitioner to accurately comply with and report their client's S corporation activities. Discuss the common errors practitioners make on S corporation tax returns that are often missed by review staff. The intent is to sharpen the skills of reviewers by examining case studies and discussing issues where additional information from the client may be warranted and areas of tax law where proper treatment requires further analysis and information. Multiple issues will be addressed, including income, deductions, K-1 reporting, and K-2 and K-3 reporting. This course follows a highly illustrative case study format to increase participant comprehension and retention.
