Understanding the 3.8% Investment Income Tax: What You Need to Know

Effective January 1, 2013, individual taxpayers became liable for a 3.8 percent Net Investment Income Tax on their investment income. This tax applies to the lesser of their net investment income or the amount by which their modified adjusted gross income exceeds the statutory threshold amount based on their filing status.

What is Net Investment Income?

Net Investment Income includes various types of income such as:

• Interest
• Dividends
• Rental and royalty income
• Capital gains
• Non-qualified annuities

However, it does not include income from wages, unemployment compensation, operating income from a non-passive business, social security benefits, or distributions from certain retirement plans.

Who is Subject to the 3.8% Investment Income Tax?

The Net Investment Income Tax applies to individuals whose modified adjusted gross income (MAGI) exceeds the following threshold amounts:

• $200,000 for single filers
• $250,000 for married individuals filing jointly
• $125,000 for married individuals filing separately

If your MAGI is below these thresholds, you will not owe the Net Investment Income Tax.

How is the 3.8% Investment Income Tax Calculated?

The Net Investment Income Tax is calculated as 3.8% of the lesser of your net investment income or the amount by which your MAGI exceeds the applicable threshold amount.

Examples:

Example 1: John is a single taxpayer with a net investment income of $50,000 and a MAGI of $220,000. Since his MAGI exceeds the threshold amount of $200,000, he will owe the Net Investment Income Tax on the lesser of his net investment income or the excess of his MAGI over the threshold. In this case, the tax will be 3.8% of $50,000, which is $1,900.

Example 2: Sarah is married and filing jointly with her spouse. They have a net investment income of $100,000 and a MAGI of $240,000. Since their MAGI exceeds the threshold amount of $250,000 for married individuals filing jointly, they will owe the Net Investment Income Tax on the lesser of their net investment income or the excess of their MAGI over the threshold. In this case, the tax will be 3.8% of $100,000, which is $3,800.

Reporting and Paying the 3.8% Investment Income Tax

The Net Investment Income Tax is reported and paid using Form 1040. It is calculated on Schedule D and reported on Line 63 of Form 1040. If you owe the tax, it will be added to your total tax liability on your tax return.

Reducing Your Net Investment Income Tax Liability

There are various strategies you can employ to reduce your Net Investment Income Tax liability. Some of these strategies include:

• Maximizing contributions to tax-advantaged retirement accounts
• Utilizing tax-efficient investment strategies
• Engaging in tax-loss harvesting
• Donating appreciated assets to charity

It is advisable to consult with a tax professional to determine the best strategies for your specific situation.
