What Is Unearned Income and How Is It Taxed?

Unearned income is money you receive from sources other than working a job or running a business, including interest, dividends, capital gains, rental payments, royalties, and retirement distributions. The IRS taxes most of it, but the rules differ sharply from wages: no payroll taxes apply, some categories get preferential rates, and higher earners face an additional 3.8% surtax on investment income once modified adjusted gross income crosses $200,000 (single) or $250,000 (married filing jointly).

What Counts as Unearned Income

The federal SSI regulations put the definition plainly: unearned income is “all income that is not earned income.”1eCFR. 20 CFR 416.1120 – What Is Unearned Income The most common categories:

  • Interest paid by banks on savings accounts, CDs, and bonds.
  • Dividends distributed by companies to shareholders.
  • Capital gains from selling stock, real estate, cryptocurrency, or other assets for more than you paid.
  • Rental income from tenants on property you own.
  • Retirement distributions from 401(k) plans, traditional IRAs, pensions, and annuities.
  • Social Security benefits, a portion of which may be taxable depending on your total income.
  • Unemployment compensation, fully taxable at the federal level.
  • Royalties from copyrights, patents, or mineral rights, reported on Schedule E unless you created the work as part of an active business, in which case they go on Schedule C.2Internal Revenue Service. What Is Taxable and Nontaxable Income
  • Gambling winnings and prizes, including lottery payouts, casino winnings, and the fair market value of non-cash awards like cars and trips.3Internal Revenue Service. Topic No. 419, Gambling Income and Losses
  • Alimony from divorce or separation agreements finalized before 2019. Agreements finalized after 2018 changed this: the recipient no longer includes alimony in gross income, and the payer can no longer deduct it.4Internal Revenue Service. Topic No. 452, Alimony and Separate Maintenance

What Doesn’t Count (or Gets Special Treatment)

A few things that look like unearned income either aren’t income at all or receive different treatment.

Gifts and inheritances. Money or property you receive as a gift or inheritance isn’t reported as income. The person making the gift may need to file a gift tax return if they give more than $19,000 to any one person in a year, but the recipient owes nothing on the transfer itself. If you later sell inherited property for more than its fair market value on the date the previous owner died, the profit is a taxable capital gain.5Internal Revenue Service. Gifts and Inheritances

Municipal bond interest. Interest on state and local government bonds is generally excluded from federal gross income under the Internal Revenue Code.6Office of the Law Revision Counsel. 26 U.S. Code 103 – Interest on State and Local Bonds The interest can still count toward modified adjusted gross income for purposes like ACA subsidy eligibility.

Post-2018 alimony. As noted above, alimony under agreements finalized after 2018 is not included in the recipient’s gross income at all.

How Unearned Income Is Taxed

Tax treatment varies dramatically by type. Some categories are taxed at ordinary rates, others get preferential rates, and a surtax layers on top for higher earners. The consistent advantage over wages: no payroll taxes.

No Payroll Taxes, but a Surtax on Investment Income

Wages carry a combined 12.4% Social Security tax and 2.9% Medicare tax, split between employee and employer.7Internal Revenue Service. Self-Employment Tax (Social Security and Medicare Taxes) Unearned income escapes both. That means investment income effectively avoids the 7.65% employee share an equivalent paycheck would owe.

The trade-off for higher earners is the Net Investment Income Tax. If your modified adjusted gross income exceeds $200,000 (single) or $250,000 (married filing jointly), you owe an additional 3.8% on your net investment income, or on the amount by which MAGI exceeds the threshold, whichever is less.8Office of the Law Revision Counsel. 26 USC 1411 – Imposition of Tax Those thresholds are not adjusted for inflation, so more taxpayers cross them each year. Net investment income for this purpose includes interest, dividends, capital gains, rental income, and royalties.

Short-Term vs. Long-Term Capital Gains

How long you hold an asset determines the rate you pay when you sell. Assets held one year or less produce short-term capital gains, taxed at your ordinary income rate. For 2026, ordinary rates run from 10% to 37%.9Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026

Assets held longer than a year qualify for preferential long-term capital gains rates. For 2026:

  • 0% if your taxable income is up to $49,450 (single) or $98,900 (married filing jointly).
  • 15% above those amounts and below $545,500 (single) or $613,700 (married filing jointly).
  • 20% on taxable income above $545,500 (single) or $613,700 (married filing jointly).9Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026

Qualified dividends, paid by most U.S. corporations and held for a minimum period, are taxed at those same preferential rates. Ordinary dividends that don’t meet the requirements are taxed at your regular rate. Interest, rental income, and retirement distributions are generally taxed at ordinary rates as well. There’s no preferential rate for savings account interest or 401(k) withdrawals.

The Kiddie Tax

Congress long ago closed the loophole of shifting large investments into a child’s name to use the child’s lower bracket. Under the kiddie tax, children under 18 (or under 24 if a full-time student whose earned income doesn’t cover half their own support) pay tax on unearned income above a set threshold at the parents’ marginal rate rather than their own.10Office of the Law Revision Counsel. 26 USC 1 – Tax Imposed

The math works in three layers. The child’s first slice of unearned income (equal to the dependent standard deduction, $1,350 in 2025) is covered by that standard deduction and isn’t taxed. The next equal slice is taxed at the child’s own rate. Everything above that, above $2,700 in 2025, gets taxed at the parents’ rate.11Internal Revenue Service. Topic No. 553, Tax on a Child’s Investment and Other Unearned Income These thresholds adjust for inflation, so check the current-year figures.

Passive Activity Loss Rules

Rental property and limited partnership interests can generate losses, but you generally can’t use those passive losses to offset wages, interest, or other nonpassive income. Passive losses can only offset passive income. One exception matters for many small landlords: if you actively participate in managing rental real estate, you can deduct up to $25,000 in rental losses against other income. That allowance phases out once your modified AGI reaches $100,000 and disappears entirely at $150,000.12Internal Revenue Service. Publication 925, Passive Activity and At-Risk Rules Losses you can’t use in the current year carry forward.

Paying Tax During the Year: Estimated Payments

Wages have taxes withheld automatically. Unearned income usually doesn’t. If you receive substantial investment income, rental income, or retirement distributions without adequate withholding, you’re expected to make quarterly estimated payments. The IRS requires them if you expect to owe $1,000 or more in tax after subtracting withholding and credits.13Taxpayer Advocate Service. Making Estimated Payments

For the 2026 tax year, quarterly payments are due April 15, June 15, and September 15 of 2026, plus January 15, 2027. You can skip the January payment if you file your full return and pay the balance by February 1, 2027.14Internal Revenue Service. 2026 Form 1040-ES – Estimated Tax for Individuals

Miss the payments and an underpayment penalty applies. To avoid it, pay at least 90% of your current-year tax liability or 100% of last year’s, whichever is less. If prior-year adjusted gross income exceeded $150,000 ($75,000 if married filing separately), the prior-year safe harbor rises to 110%.15Internal Revenue Service. Underpayment of Estimated Tax by Individuals Penalty This is a common first-year surprise for people who begin receiving significant investment income.

Forms You’ll See and File

Financial institutions send copies of 1099 forms to the IRS, so the agency already has a record of your interest and dividends before you file. The main forms:

If total taxable interest or ordinary dividends exceed $1,500 for the year, file Schedule B with your return.17Internal Revenue Service. 2025 Instructions for Schedule B (Form 1040) Capital gains and losses go on Schedule D, with individual transactions detailed on Form 8949. Rental income and royalties go on Schedule E.

One requirement people miss: if you hold money in foreign bank accounts and their combined value exceeds $10,000 at any point during the year, you must file a Report of Foreign Bank and Financial Accounts (FBAR) on FinCEN Form 114. That obligation applies whether or not the accounts earned income.18Internal Revenue Service. Report of Foreign Bank and Financial Accounts (FBAR)

How Unearned Income Affects Benefits and Health Coverage

Tax isn’t the only issue. Unearned income can reduce government benefits and change what you pay for health insurance.

Supplemental Security Income

SSI applies a strict formula. After a $20 monthly general exclusion, every additional dollar of unearned income reduces the SSI benefit dollar-for-dollar.19Social Security Administration. Code of Federal Regulations 416.1124 Even modest amounts of interest or dividends can noticeably shrink a monthly check.

ACA Marketplace Subsidies

Eligibility for premium tax credits on marketplace health insurance depends on modified adjusted gross income, and most unearned income counts. Investment income, rental income, retirement withdrawals (other than Roth distributions), and even tax-exempt municipal bond interest all factor in.20HealthCare.gov. What’s Included as Income A large capital gain in a single year can push MAGI above the subsidy threshold and leave you paying full price for coverage.

Some categories don’t count toward MAGI for marketplace purposes: Supplemental Security Income, veterans’ disability payments, and workers’ compensation.20HealthCare.gov. What’s Included as Income

Penalties for Underreporting

Because 1099 forms flow to the IRS directly, underreported unearned income is easy to catch through automated matching. If a discrepancy surfaces, the accuracy-related penalty adds 20% on top of the underpaid tax.21Office of the Law Revision Counsel. 26 U.S. Code 6662 – Imposition of Accuracy-Related Penalty on Underpayments

The penalty doubles to 40% for undisclosed foreign financial asset understatements. If you failed to report income from overseas accounts and also skipped the FBAR, consequences escalate fast.21Office of the Law Revision Counsel. 26 U.S. Code 6662 – Imposition of Accuracy-Related Penalty on Underpayments Separate FBAR penalties are steeper still. The safest approach is straightforward: report every 1099 you receive, however small. The IRS matches all of them.
