What IRS Form 8960 (2020) Is For
IRS Form 8960 (2020) is used to calculate the 3.8 percent net investment income tax for individuals whose income exceeds specific thresholds set by the Internal Revenue Service. It determines whether taxpayers must pay this additional tax by comparing their net investment income with their modified adjusted gross income. It applies only to investment income; it does not apply to wages or other forms of noninvestment taxable income. This form helps ensure that higher earners accurately report their investment income for the tax year.
When You’d Use IRS Form 8960 (2020)
You complete this form when your income exceeds certain thresholds, and you have investment income that may be subject to the tax imposed under NIIT.
- Your filing status creates an obligation to file IRS Form 8960 (2020). You must complete the form when your modified adjusted gross income exceeds the income threshold for your filing status, including single, head of household, married filing jointly, or married filing separately.
- You have investment income that meets NIIT requirements. You must file the form when your taxable investment income includes interest, dividends, rental income, or capital gains that require NIIT calculation.
- Your tax return includes complex income categories. You should file the form when your tax return contains items such as foreign earned income, self-employment income adjustments, or other factors that require the calculation of modified adjusted gross income.
Normas o detalles importantes para 2020
The IRS applied specific income thresholds and classification rules to determine who owes net investment income tax for the 2020 tax year.
- MAGI qualifications to trigger NIIT: You are subject to the 3.8 percent net investment income tax only if your modified adjusted gross income exceeds the applicable threshold based on your filing status.
- The core of the calculation: Net investment income includes capital gains, dividends, interest, rental income, and other passive income; it excludes earned income, such as wages or self-employment income.
- Adjusted gross income and specific add-backs: Your MAGI is based on your adjusted gross income plus certain items such as excluded foreign earned income, housing deductions, or tax-exempt interest.
- Rental income may be excluded: If you are a qualified real estate professional who materially participates in rental activities, your rental income may be excluded from NIIT.
- Retirement distributions are not subject to NIIT: Distributions from retirement plans, including Roth IRAs, traditional IRAs, and similar qualified plans, are not considered net investment income.
- Not included: Social Security benefits and unemployment compensation are types of income that are not included in the calculation of net investment income for IRS Form 8960 (2020).

Paso a paso (visión general)
Completing IRS Form 8960 (2020) involves three main sections that work together to determine your NIIT liability.
- Part I – Calculate Gross Investment Income and Apply Necessary Adjustments: You begin by reporting all relevant investment income, including interest, dividends, capital gains, and rental income. Then, adjust for amounts excluded under NIIT rules, such as active business income.
- Part II – Subtract deductible investment-related expenses to compute net investment income: You reduce your investment income by reporting eligible deductions such as investment interest expense, state and local income taxes related to investment income, and applicable advisory or tax preparation fees.
- Part III – Compare MAGI to the threshold and calculate the tax owed: You determine how much your modified adjusted gross income exceeds the threshold for your filing status, compare that to your net investment income, and apply the 3.8 percent rate to the lesser amount to calculate the tax.

Errores comunes y cómo evitarlos
Taxpayers frequently make filing errors with IRS Form 8960 (2020), but many of these can be prevented with proper review and documentation.
- Double-counting deductible expenses: You should avoid reporting the same investment interest or tax deduction on both Form 8960 and other schedules, such as Schedule A or Schedule E.
- Using incorrect income thresholds for filing status: You must confirm that you are applying the correct threshold amount based on your filing status, such as single, head of household, married filing jointly, or married filing separately.
- Claiming disallowed or expired deductions: You should not claim miscellaneous itemized deductions that were suspended under the Tax Cuts and Jobs Act, or deductions that do not apply to investment income.
- Omitting income from passive activities: You must include passive income, such as rental or partnership earnings, where you do not materially participate, as this type of income is considered net investment income.
- Failing to attach election statements when required: You need to attach a properly formatted statement when making special elections for foreign investments, such as controlled foreign corporations or passive foreign investment companies.
- Relying solely on tax software without review: You should carefully review all calculations made by tax software, particularly those involving passive activities, foreign earned income, or investment income grouping.
¿Qué ocurre después de presentar la solicitud?
Once you file IRS Form 8960 (2020) with your tax return, the Internal Revenue Service will assess whether the calculated Net Investment Income Tax has been appropriately applied. If you owe NIIT, the 3.8 percent tax will be included in your total tax liability on Schedule 2 of Form 1040. If you later identify an error or omission, you may need to file an amended return using Form 1040-X with an updated Form 8960.
If you’re unable to pay your NIIT liability in full, an Offer in Compromise for IRS debt may provide an option to settle your tax bill for less than the total amount owed.
Preguntas frecuentes
What is modified adjusted gross income (MAGI)?
Your modified adjusted gross income (MAGI) is your adjusted gross income (AGI) plus certain tax deductions added back in, such as foreign earned income or student loan interest deduction. MAGI is used to determine your eligibility for tax benefits and whether you are subject to the 3.8 percent net investment income tax (NIIT).
What is undistributed net investment income?
Undistributed net investment income generally refers to investment income earned by estates or trusts that is not passed on to beneficiaries. This income may still be subject to the 3.8 percent net investment income tax even though it is not distributed. It must be reported using IRS Form 8960 (2020).
Does the child tax credit affect IRS Form 8960 (2020)?
The child tax credit does not reduce your net investment income or directly affect NIIT calculations. However, it may reduce your regular income tax liability, which is a separate consideration from how your capital gains tax or investment income tax NIIT is determined.
Are Roth IRA contributions included in investment income for NIIT?
Roth IRA contributions are not included as investment income and are not subject to the 3.8 percent net investment income tax. Additionally, qualified distributions from Roth IRAs do not increase your MAGI and are excluded from both capital gains tax and NIIT calculations.
