Training Case Study

Case overview

What the return required.

This training case involved a married filing jointly senior return with wage income, taxable and tax-exempt interest, dividends, IRA distributions, pension income, Social Security benefits, capital transactions, additional income, and two dependent scenarios. The return also incorporated Form 982 cancellation-of-debt treatment and California federal-to-state adjustments, creating a materially different preparation and review workflow from the other portfolio cases.
