When preparing your federal income tax return, it’s important to understand that some taxpayers may be subject to an additional tax known as the Net Investment Income Tax (NIIT). Although it doesn’t apply to everyone, individuals with higher levels of income and investment earnings should understand how this tax works and whether it may affect their overall tax liability.

The NIIT is a 3.8% federal tax that may apply to certain types of investment income when your modified adjusted gross income (MAGI) exceeds specific IRS thresholds. Investment income can include interest, dividends, capital gains, rental income, royalties, and certain passive business income. However, wages, self-employment income, Social Security benefits, most retirement plan distributions, and tax-exempt interest generally are not considered net investment income for purposes of this tax.

The NIIT is calculated based on the lesser of your net investment income or the amount by which your MAGI exceeds the applicable threshold for your filing status. Because of this calculation, determining whether the tax applies can be more complex than simply reviewing your investment earnings.

Tax planning can play an important role in managing the impact of the NIIT. Timing the sale of investments, understanding the difference between passive and non-passive income, harvesting capital losses, and coordinating retirement or estate planning strategies may help reduce exposure to this additional tax. Since every taxpayer’s financial situation is unique, personalized planning is often the best approach.

Many taxpayers are surprised to learn that a significant increase in investment income—such as the sale of appreciated stock, rental property, or other investments—may trigger the NIIT even if they have never owed it before. That’s why reviewing major financial transactions before the end of the year can be beneficial.
