Original Description

The net investment income tax (NIIT) is a 3.8% surtax that often catches taxpayers and preparers off guard, quietly increasing the tax bill once income exceeds statutory thresholds. In this webinar, we will break down exactly when the tax is triggered, how to pinpoint what qualifies as net investment income and how to correctly perform the NIIT calculation for individual taxpayers. We will also address common preparation and review pitfalls, including frequently overlooked exclusions from NII and deductions that can be strategically allocated to reduce tax exposure. The session concludes with a practical walk-through of the reporting requirements, including accurate completion of Form 8960, Net Investment Income Tax—Individuals, Estates, and Trusts.
