This tax applies to individuals, estates, and trusts that have net investment income above certain thresholds. In this comprehensive guide, we will answer some of the most frequently asked questions about the Net Investment Income Tax and provide you with all the information you need to understand how it may affect your taxes.

What is the Net Investment Income Tax (NIIT)?

The Net Investment Income Tax (NIIT) is a 3.8% tax that is imposed on certain types of investment income. This tax was introduced as part of the Affordable Care Act and is designed to help fund Medicare. The NIIT applies to individuals, estates, and trusts that have net investment income above certain thresholds.

When did the Net Investment Income Tax take effect?

The Net Investment Income Tax took effect on January 1, 2013. This means that if you had net investment income above the threshold in 2013 or later, you may be subject to the NIIT.

Who is subject to the Net Investment Income Tax?

Individuals, estates, and trusts may be subject to the Net Investment Income Tax if they have net investment income above certain thresholds. The thresholds vary depending on filing status:

• Single filers: $200,000
• Married filing jointly: $250,000
• Married filing separately: $125,000

If your modified adjusted gross income (MAGI) exceeds these thresholds and you have net investment income, you may be subject to the NIIT.

What is included in Net Investment Income?

Net investment income includes several types of income, such as:

• Interest
• Dividends
• Rent and royalty income
• Capital gains
• Passive income from partnerships, S corporations, and trusts

It's important to note that not all types of income are included in net investment income. For example, wages, self-employment income, and income from retirement accounts are not considered net investment income.

How is the Net Investment Income Tax reported and paid?

The Net Investment Income Tax is reported and paid along with your regular income tax return. You will need to complete Form 8960, Net Investment Income Tax, to calculate the amount of tax you owe. The NIIT is subject to the estimated tax provisions, so you may need to make estimated tax payments throughout the year if you expect to owe more than a certain amount.

Are there any deductions or credits that can reduce the Net Investment Income Tax liability?

There are some deductions and credits that can reduce your Net Investment Income Tax liability. For example, if you have investment expenses that are deductible, you can subtract them from your net investment income. Additionally, certain tax credits can also reduce your NIIT liability.

Can the Net Investment Income Tax be withheld from wages?

The Net Investment Income Tax cannot be withheld from wages. Unlike regular income tax, which is typically withheld by employers from your paycheck, the NIIT is not subject to withholding. This means that you will need to plan accordingly and make sure you have enough funds to cover your tax liability.
