Description

Shareholder basis is one of the most misunderstood areas of S corporation taxation, and Form 7203 has made it a mandatory part of the individual tax return for most shareholders. This session walks through the mechanics of stock and debt basis, how distributions and losses affect it, and exactly how to complete Form 7203 line by line so returns hold up under IRS scrutiny.

Because many practitioners inherit clients whose basis was never properly tracked, a major focus of this webinar is reconstruction: how to rebuild a shareholder's basis history from incomplete records, prior returns, and K-1s. Attendees will leave with a practical, repeatable process for both new engagements and long-standing S corp clients.
