Form 8960: Net Investment Income Tax Overview (2024)

Filing Form 8960 can be confusing for many taxpayers.

This guide will clearly explain who needs to file Form 8960, how to calculate net investment income tax, and strategies to minimize or avoid the tax.

You'll learn key concepts like modified adjusted gross income thresholds, step-by-step instructions for completing the form, computing total liability, reporting on tax returns, and tax planning methods to reduce your tax burden.

Introduction to Form 8960 and the Net Investment Income Tax

Form 8960 is used to calculate and report the Net Investment Income Tax (NIIT). This tax applies to individuals, estates, and trusts that have net investment income above certain thresholds.

Understanding the Purpose of Form 8960

The purpose of Form 8960 is to:

Calculate the NIIT liability based on net investment income
Report that tax liability on the taxpayer's income tax return

The NIIT applies in addition to regular income tax and is intended to ensure that higher-income taxpayers pay a minimum level of tax on investment income.

Determining Who Should File Form 8960

You must file Form 8960 if:

You are an individual, estate, or trust
Your modified adjusted gross income exceeds $200,000 for single/head of household, $250,000 if married filing jointly, or $13,050 for an estate or trust
You have net investment income greater than the thresholds above

So this form applies to higher-income taxpayers with substantial investment income from interest, dividends, capital gains, etc.

Key Concepts: Net Investment Income and Modified Adjusted Gross Income

Net Investment Income includes income from interest, dividends, capital gains, rental income, income from non-qualified annuities, royalties, and passive income from partnerships/S-corporations.
Modified Adjusted Gross Income is your regular adjusted gross income with certain foreign and NOL deductions added back. This determines if you meet the MAGI thresholds for the NIIT.

Understanding these definitions is key to calculating the NIIT correctly on Form 8960.

Who needs to file IRS form 8960?

The IRS Form 8960, also known as the Net Investment Income Tax (NIIT) form, must be filed by certain individuals, estates, and trusts that meet specific modified adjusted gross income (MAGI) thresholds.

Specifically, you generally need to file Form 8960 if:

You file a joint tax return and your MAGI is over $250,000
You file taxes as a qualifying widow(er) and your MAGI is over $250,000
You file taxes separately and your MAGI is over $125,000
You file taxes as single or head of household and your MAGI is over $200,000

So in summary, if your filing status is married filing jointly, qualifying widow(er), or married filing separately, and your MAGI exceeds $250,000 or $125,000 respectively, you must file Form 8960. And if your filing status is single or head of household and your MAGI exceeds $200,000, you must file as well.

The Net Investment Income Tax is a 3.8% tax that applies to certain net investment income of individuals, estates, and trusts that have income above those thresholds. So by filing Form 8960, you are reporting any tax liability you may have under the Net Investment Income Tax provisions.

What is the net investment income tax for estates and trusts?

The net investment income tax (NIIT) is an additional 3.8% tax that applies to certain net investment income of individuals, estates, and trusts. For estates and trusts, the NIIT applies if the estate or trust has undistributed net investment income and also has adjusted gross income over the statutory threshold amount for the tax year.

Here are some key things to know about the net investment income tax for estates and trusts:

The NIIT applies at a rate of 3.8% to the lesser of (1) the estate's or trust's undistributed net investment income or (2) the excess of the estate's or trust's adjusted gross income over the statutory threshold amount ($12,950 for 2021).
Net investment income generally includes interest, dividends, capital gains, rental and royalty income, non-qualified annuities, income from businesses involved in trading of financial instruments or commodities, and certain other investment income.
There are special rules for calculating net investment income and for determining what constitutes undistributed net investment income for estates and trusts. Form 8960 and its instructions provide details.
Estates and trusts with adjusted gross income at or below the statutory threshold amount are not subject to the NIIT.

In summary, the NIIT can apply to estates and trusts with substantial undistributed investment income and adjusted gross income over the threshold amount for the year. Form 8960, Net Investment Income Tax - Individuals, Estates, and Trusts, is used to calculate and report the tax.

Who is subject to NIIT tax?

The Net Investment Income Tax (NIIT), also known as the Medicare Contribution Tax, applies to individuals, estates, and trusts that have certain levels of investment income and modified adjusted gross income (MAGI). Specifically:

What is the threshold for form 8960 in 2023?

The threshold for Form 8960, Net Investment Income Tax (NIIT), varies depending on your filing status. For the 2023 tax year, the threshold amounts are:

Single or Head of Household: $250,000
Married Filing Jointly: $250,000
Married Filing Separately: $125,000
Qualifying Widow(er): $250,000

If your Modified Adjusted Gross Income (MAGI) exceeds the threshold amount for your filing status, and you have net investment income, you may be subject to the 3.8% Net Investment Income Tax.

For example, if you file single and have $260,000 of MAGI and $15,000 of net investment income, the 3.8% tax would apply to the $15,000. Your NIIT liability would be $570 (3.8% of $15,000).

Some key things to know about the NIIT threshold for 2023:

The threshold does not change from year to year due to inflation adjustments
The threshold applies separately to individuals, estates, and trusts
If your MAGI falls below the threshold, you do not owe the tax regardless of your net investment income

So in summary, for 2023 the NIIT threshold is $250,000 for most individual filers, with special rules for those who file separately or as qualifying widows or widowers. Compare your MAGI to the relevant threshold to determine if you may owe this additional 3.8% tax on net investment income.

Step-by-Step Guide to Calculating Net Investment Income

To calculate your NIIT liability:

Determine your net investment income (NII). Common sources are interest, dividends, capital gains, rental income, annuities, royalties, etc. Certain income may be excluded.
Calculate your MAGI. This includes adjusted gross income plus any foreign earned income exclusion.
Subtract the threshold amount for your filing status from your MAGI.
Compare the lesser of #1 or #3. This is your NIIT base.
Multiply your NIIT base by 3.8% to determine your tentative NIIT. Complete Form 8960 line 9b calculation.
Enter your tentative NIIT on Form 1040 line 62 or Form 1041 Schedule G line 3.

Determining Modified Adjusted Gross Income for Form 8960

To determine your MAGI for Form 8960:

Start with your adjusted gross income (AGI) from Form 1040 line 7

Calculating and Reporting the Net Investment Income Tax

The Net Investment Income Tax (NIIT) is an additional 3.8% tax that may apply to individuals, estates, and trusts on certain investment income above certain income thresholds. Here is a guide to calculating and reporting the NIIT:

Computing Total Net Investment Income Tax Liability

To calculate your NIIT liability on Form 8960:

Determine your net investment income (NII):
- Includes interest, dividends, capital gains, rental and royalty income, non-qualified annuities, income from businesses involved in trading financial instruments or commodities, and others.
- Excludes wages, self-employment income, Social Security benefits, tax-exempt interest, distributions from IRAs and qualified retirement plans, and others.
Determine your modified adjusted gross income (MAGI) based on your tax return filing status.
Compare your NII to the threshold amount for your filing status:
- Filing Single: $200,000
- Married Filing Jointly: $250,000
- Married Filing Separately: $125,000
Your NIIT liability is 3.8% of the lesser of your NII or the excess of your NII over the threshold amount based on your filing status.

For example, if your NII is $100,000 and your MAGI is $220,000 filing single, your NIIT liability would be 3.8% of $100,000, or $3,800.

How to Report Net Investment Income Tax on Tax Returns

To report your NIIT liability:

On Form 1040:

Enter your NIIT liability from Form 8960 on line 62.

On Form 1041:

Enter your NIIT liability from Form 8960 on line 24e.

On Form 8960:

Calculate your NIIT liability and enter on line 17. Attach the completed Form 8960 to your Form 1040 or Form 1041.

Understanding Non-Section 1411 Trade or Business Income

Income derived in the ordinary course of certain trades or businesses is excluded from NII and not subject to the NIIT, including:

Income from sole proprietorships and partnerships where you are actively involved in the trade or business
Income from trading financial instruments and commodities if it is your main business
Certain rental and royalty income if you are actively involved
Others as specified by the IRS

So ordinary income from an active trade or business is generally exempt from the NIIT. However, income from trading financial assets for your own account or passive rental activities would still be subject to the tax.

I hope this guide on calculating and reporting the Net Investment Income Tax on Form 8960 helps provide clarity on this additional tax. Let me know if you have any other questions!

Strategies to Minimize or Avoid Net Investment Income Tax

The Net Investment Income Tax (NIIT) is a 3.8% tax applied to certain net investment income of individuals, estates and trusts that have income above specific thresholds. Here are some potential strategies to minimize exposure or avoid the NIIT:

How to Avoid Net Investment Income Tax: Legal Strategies

Keep income below the thresholds. For individuals, the NIIT applies if modified adjusted gross income (MAGI) exceeds $200,000 for single filers or $250,000 for married filing jointly. For trusts and estates, it applies if adjusted gross income exceeds around $12,500. Staying below these income thresholds is an effective way to avoid the NIIT entirely.
Shift investments to non-passive activities. Income from a non-passive trade or business is not subject to the NIIT. Actively participate in rental real estate activities or shift investments into an active business to potentially exempt that income.
Use tax-deferred retirement accounts. Income and gains from IRAs, 401(k)s, and other tax-advantaged retirement accounts are not included in net investment income subject to the NIIT. Maxing out contributions to these accounts can help minimize exposure.
Offset with investment expenses. Properly allocable investment expenses like investment fees, margin interest, and state taxes can reduce net investment income and thus lower NIIT liability.

Tax Planning for Investment Income

Harvest capital losses. Selling securities at a loss can offset capital gains, reducing net investment income. This strategy, known as tax-loss harvesting, should be implemented carefully to avoid wash sale rule violations.
Use charitable remainder trusts (CRTs). CRTs allow you to transfer appreciated assets to a trust which sells them tax-free. You receive a stream of payments now, while the remainder goes to charity later. This may shift income outside the NIIT thresholds.
Invest in tax-exempt bonds. Earnings from municipal bonds are exempt from federal tax and thus not included in net investment income subject to the NIIT. In some cases, this strategy can minimize exposure.
Review portfolio asset location. Consider strategically locating assets between taxable and tax-deferred accounts to maximize returns after taxes and minimize NIIT exposure. Work closely with a tax professional on implementation.

Careful planning around the NIIT can help taxpayers in high income brackets significantly reduce their exposure or avoid the tax entirely through legal and appropriate means. Consulting closely with a tax advisor is highly recommended when exploring these strategies.
