What is the Net Investment Income Tax?
The Net Investment Income Tax (NIIT) is a 3.8% tax on specific types of investment income. It affects individuals, estates, and trusts who have income above certain thresholds. This tax was introduced to help fund the Affordable Care Act and applies to investment income such as interest, dividends, capital gains, and rental income.
Who is Subject to NIIT?
Individuals with a modified adjusted gross income (MAGI) above specific thresholds are subject to the NIIT. Here’s how it breaks down:
- Single filers: MAGI over $200,000
- Married filing jointly: MAGI over $250,000
- Married filing separately: MAGI over $125,000
- Head of household: MAGI over $200,000
Estates and trusts face the NIIT when they have undistributed net investment income and adjusted gross income (AGI) over the level where the highest tax bracket kicks in, which is $14,450 for 2026.
What Income is Considered Net Investment Income?
Net investment income includes, but is not limited to:
- Interest: From savings accounts, CDs, etc.
- Dividends: From stocks or mutual funds
- Capital gains: From the sale of stocks, bonds, real estate, other investments
- Rental and royalty income
- Non-qualified annuities
Some income types are not included, such as wages, unemployment compensation, and Social Security benefits.
How is NIIT Calculated?
The NIIT is calculated as 3.8% of the lesser of:
- Your net investment income for the year, or
- The amount by which your MAGI exceeds the threshold for your filing status.
For example, if a single filer has a MAGI of $220,000 and net investment income of $30,000, the tax is calculated on the lesser of the $20,000 over the threshold or the $30,000 of investment income. Therefore, the NIIT would be 3.8% of $20,000, which equals $760.
Strategies to Minimize NIIT
Here are some strategies that may help reduce your exposure to the NIIT:
- Tax-deferred accounts: Use retirement accounts like 401(k)s and IRAs to defer taxes on investment income.
- Tax-exempt investments: Consider municipal bonds, which pay interest that is exempt from federal tax and, thus, NIIT.
- Dividends: Focus on qualified dividends, which may be taxed at a lower rate compared to ordinary income.
- Capital gains timing: Strategically realize gains in years when your income might be below the threshold.
- Loss harvesting: Offset gains by selling investments at a loss in the same tax year.
These strategies can be complex and might benefit from the advice of a tax professional.
