This course will provide tax advisers with a comprehensive and practical guide to mastering the tax reporting of 1099 brokerage statements on Form 1040 Schedule D and Form 8949. The panel will go beyond the basics to offer an in-depth tutorial on making adjustments to reported asset basis and navigating specific challenges, such as reporting for high-volume and day traders, discerning dealer vs. investor questions for clients selling real estate, identifying wash sale issues, and preparing reconciliation schedules to support reporting variances on Form 8949.


Five years after the IRS began requiring brokers to report basis in securities sold by U.S. taxpayers during a calendar year, tax advisers continue to struggle with key tax compliance complexities. While some tax reporting for transactions involving covered securities is straightforward, advisers are often faced with complex calculations and time-consuming data collection and analysis.

Taxpayers are required to reconcile basis information provided by brokers on Form 1099-B with their calculations of gains and losses on Schedule D using Form 8949. However, this reconciliation also presents specific complications for tax advisers, particularly in situations where the client is a high-volume trader, has multiple brokerage accounts, has transactions that may have wash sale loss disallowance, or has investments in real estate.

There are numerous other complexities in reporting transactions involving capital assets. Taxpayers receiving assets through gift or inheritance can face significant challenges in determining basis, especially when the assets are foreign-based. Section 1202 small business stock can also present calculation and reporting issues.

Listen as our experienced panel provides a thorough and practical guide to the challenges of Form 1099-B reporting on clients’ 1040 returns. The panel will outline approaches to properly report capital gains and anticipate potential audit red flags and common cost basis reporting errors.
