What IRS Form 8960 (2012) Is For
IRS Form 8960 (2012) is used to calculate the Net Investment Income Tax that applies when individuals' estates and trusts have investment income, and their modified adjusted gross income exceeds specific threshold amounts. It identifies investment income that is subject to this tax for federal income tax purposes and separates it from income that is not included in this category. It also ensures that taxpayers correctly apply income threshold rules that determine when the net investment income tax applies for the relevant tax year.
When You’d Use IRS Form 8960 (2012)
You would use IRS Form 8960 (2012) when your investment income and filing status place you within the group that is subject to the tax for the applicable threshold amounts.
- Filing when net investment income tax applies: You must file Form 8960 when your modified adjusted gross income exceeds the statutory threshold for your filing status and your investment income results in a liability for this tax.
- Late or amended income tax returns: You must file Form 8960 with Form 1040-X if you later determine that you were subject to the tax and did not initially include this form with your income tax returns.
- Special rules for estate or trust filing: You must file the form when an estate or trust has undistributed net investment income that exceeds the dollar amount at which the highest tax bracket begins for that entity.
- Filing with specific statuses: You must file this form when married filing jointly, married filing separately, a single taxpayer, a head of household, or a qualifying surviving spouse if your income exceeds the applicable threshold amounts for that filing status.
- Foreign income considerations: You may need to complete this form when you have foreign earned income, and the foreign earned income exclusion affects whether your filing status MAGI threshold has been exceeded.
Key Rules or Details for the 2012 Tax Year
You should understand several rules that determine how IRS Form 8960 (2012) applies to income and filing thresholds for the Net Investment Income Tax.
- Income types included: Net investment income includes capital gains, dividends, interest, mutual funds, real estate investment trusts, passive partnership interests, annuities, and other investment income considered net investment income for federal income tax purposes.
- Income types excluded: Net investment income does not include social security benefits, unemployment compensation, self-employment income, tax-exempt interest, traditional IRA distributions, or other income excluded explicitly under the tax code for regular income tax purposes.
- MAGI thresholds: Net investment income tax applies when the taxpayer’s adjusted gross income MAGI exceeds the statutory threshold amounts that vary based on filing status for the relevant tax year.
- Estate and trust rules: NIIT applies to undistributed net investment income of an estate or trust once the highest tax bracket begins at the applicable dollar amount for that tax year.
If you receive penalties for errors or late filing related to IRS Form 8960, ask about IRS penalty abatement to help reduce or remove those charges.
Step-by-Step (High Level)
- Calculate total investment income: Taxpayers must combine dividends, interest, capital gains, rental income, passive income, and other investment income to determine their gross income, which will be evaluated for NIIT.
- Subtract allocable investment expenses: Taxpayers must subtract properly allocable investment expenses, such as advisory fees, state or local taxes, and similar charges, to determine their net income for this tax.
- Determine MAGI amounts: Taxpayers must calculate their adjusted gross income (AGI) and compare it to the threshold amounts established by the Internal Revenue Service (IRS) for their filing status.
- Compare MAGI excess to the taxpayer's net investment income: Taxpayers must determine whether the excess MAGI amount or the taxpayer’s net investment income is the smaller figure, since this determines the amount subject to NIIT.
- Compute final tax liability: Taxpayers must calculate the final tax liability by applying the NIIT rate to the appropriate amount and then including this figure on their income tax return, as required by the Internal Revenue Service.
Common Mistakes and How to Avoid Them
Several errors can occur when completing IRS Form 8960 (2012), and understanding them can help taxpayers avoid issues that affect net investment income tax calculations.
- Misclassifying income types: Taxpayers can avoid errors by ensuring that wages, social security benefits, unemployment compensation, or self-employment income are not treated as net investment income since these categories are not subject to the NIIT.
- Ignoring the home sale exclusion: Taxpayers can avoid overstating net investment income by excluding gain from the sale of a personal residence when the exclusion rules for real estate apply.
- Incorrect material participation claims: Taxpayers can avoid incorrect passive activity treatment by carefully reviewing participation rules, especially when determining whether real estate activities qualify as those of a qualified real estate professional.
- Estate or trust threshold errors: Executors or trustees can avoid NIIT miscalculations by confirming the exact point at which the highest tax bracket begins for an estate or trust in the relevant tax year.
- Deduction allocation mistakes: Taxpayers can avoid errors by allocating investment expenses only to income categories that are subject to the NIIT rather than to excluded income types or unrelated items.
Addressing any unfiled individual returns is essential to ensure all net investment income is reported correctly and to prevent IRS penalties for missed income.
What Happens After You File
After you file IRS Form 8960 (2012), the Internal Revenue Service reviews the calculation of the net investment income tax along with your overall tax return. The IRS may issue notices if adjustments are required; these may involve unreported investment income, incorrect MAGI amounts, or misclassified income. Refunds may decrease if the tax increases your total liability, or balances due may increase if the net investment income tax was not paid on time.
If your net investment income tax increases your balance due, IRS payment plans can help you pay your tax over time and avoid additional penalties.
