Under Section 61 of the Internal Revenue Code, gross income means all income from whatever source derived. That single phrase does most of the work. If a transaction leaves you wealthier and no other Code section excludes it, the IRS treats the gain as taxable. The statute lists fourteen familiar categories — wages, business profits, interest, dividends, rents, royalties, and so on — but the list is illustrative, not a limit. Anything not on it is still income if it fits the definition.1Office of the Law Revision Counsel. 26 U.S. Code 61 – Gross Income Defined
The Supreme Court fixed the reach of that phrase in 1955. In Commissioner v. Glenshaw Glass Co., the Court held that gross income covers “undeniable accessions to wealth, clearly realized, and over which the taxpayers have complete dominion.” Three elements: you got richer, the gain is real rather than paper, and the money is yours to control. Courts still apply that test to every close question about what counts.2Justia U.S. Supreme Court Center. Commissioner v. Glenshaw Glass Co.
The practical consequence is that the burden runs against the taxpayer. Congress must carve out each exception by statute. Section 61 gives no ground on its own.
What Clearly Counts as Gross Income
Compensation for Work
Wages, salaries, commissions, tips, bonuses, and severance are all gross income. Employers report these on Form W-2; contractor pay shows up on Form 1099-NEC. The full amount is included before any withholding for taxes or benefits.
Compensation does not have to arrive as cash. If your employer pays you in property or services, you include the fair market value of what you received. A consultant paid with $5,000 of equipment has $5,000 of gross income even though no dollars changed hands.
Business Income
If you run a business, gross income is total revenue from sales or services before subtracting costs. Sole proprietors report this on Schedule C. Net profit is subject to both income tax and self-employment tax. Partnerships and S corporations pass income through to the owners, and each owner’s share is included in the owner’s gross income.3Internal Revenue Service. Schedule C Profit or Loss From Business
Gains From Selling Property
When you sell an asset for more than your adjusted basis (generally what you paid plus improvements), the profit is gross income. You report the gain on Form 8949 and Schedule D. Property held one year or less produces a short-term gain taxed at ordinary rates; property held longer than a year qualifies for long-term capital gains rates of 0%, 15%, or 20%.4Internal Revenue Service. About Form 8949, Sales and Other Dispositions of Capital Assets
Realization matters. A stock that doubles in your brokerage account has not produced gross income yet. The gain becomes real, and taxable, only when you sell.
Interest, Dividends, Rents, and Royalties
Interest on bank accounts, CDs, corporate bonds, and personal loans is fully included in gross income, reported on Form 1099-INT. Under the cash method used by most individuals, you report interest in the year it is credited to your account, even if you leave it there.5Internal Revenue Service. About Form 1099-INT, Interest Income Original issue discount — the built-in interest on a bond sold below face value — is reported each year on Form 1099-OID even though the cash arrives only at maturity.6Internal Revenue Service. About Form 1099-OID, Original Issue Discount
Dividends paid out of corporate earnings are gross income, reported on Form 1099-DIV. Ordinary dividends are taxed at your regular rate. Qualified dividends are taxed at long-term capital gains rates if you held the underlying stock for at least 61 days during the 121-day period beginning 60 days before the ex-dividend date.7Internal Revenue Service. Topic No. 404, Dividends and Other Corporate Distributions
Rent for the use of real estate or equipment and royalties for the use of patents or copyrights are gross income, reported on Schedule E. Prepaid rent is taxed in the year received, no matter what period it covers.8Internal Revenue Service. About Schedule E (Form 1040), Supplemental Income and Loss
Retirement and Government Benefits
Distributions from a pension, traditional 401(k), or traditional IRA are generally included in gross income because the contributions were never taxed. If you made after-tax contributions, an exclusion ratio treats part of each payment as a nontaxable return of your own money. Roth distributions funded with after-tax dollars are generally tax-free.
Social Security retirement and disability benefits can be partially included in gross income depending on your total income, with up to 50% or up to 85% becoming taxable at the statutory thresholds. Supplemental Security Income is not taxable.9Office of the Law Revision Counsel. 26 U.S. Code 86 – Social Security and Tier 1 Railroad Retirement Benefits10Internal Revenue Service. Social Security Income
Unemployment compensation is fully taxable at the federal level. Any amount received under a federal or state unemployment program must be reported.11Office of the Law Revision Counsel. 26 U.S. Code 85 – Unemployment Compensation
Alimony
The rule depends on when the divorce or separation agreement was signed. For agreements executed on or before December 31, 2018, the recipient includes alimony in gross income and the payer deducts it. For agreements executed after that date, the Tax Cuts and Jobs Act eliminated both sides of the treatment, making alimony tax-neutral. Pre-2019 agreements later modified fall under the new rules only if the modification specifically adopts the TCJA changes.12Internal Revenue Service. Divorce or Separation May Have an Effect on Taxes13U.S. Congress. Public Law 115-97 – Tax Cuts and Jobs Act
Child support is different. It has never been included in the recipient’s gross income and has never been deductible by the payer, regardless of when the agreement was signed.14Internal Revenue Service. Dependents 6
Sources People Are Surprised to Learn Are Taxable
Section 61 does not care about the circumstances. If you ended up wealthier, the IRS wants its share, even if the source is unusual or unlawful.
Illegal Income
Income from theft, embezzlement, drug sales, bribery, and any other illegal activity is fully taxable. The Supreme Court confirmed this in James v. United States, holding that embezzled funds are gross income because the embezzler exercises complete control over the money. Reporting illegal income does not violate the Fifth Amendment.15Justia U.S. Supreme Court Center. James v. United States, 366 U.S. 213 (1961) People running illegal businesses can generally deduct ordinary business expenses, with one major exception: businesses trafficking in controlled substances on federal Schedules I and II cannot deduct anything beyond cost of goods sold.16Office of the Law Revision Counsel. 26 U.S. Code 280E – Expenditures in Connection with the Illegal Sale of Drugs
Prizes, Awards, and Found Property
Lottery winnings, raffle prizes, game show payouts, and contest awards are all gross income. If the prize is property rather than cash, you include the fair market value. Win a $40,000 car and you owe tax on $40,000 even though no check ever arrives. Large gambling winnings are subject to 24% federal withholding at payout, though your actual liability depends on your overall income.
Even money you stumble across counts. Property discovered as a treasure trove is gross income at fair market value in the year you take undisputed possession. Find $5,000 in an old safe and you have $5,000 of taxable income.
Bartering
If you swap services or property instead of paying cash, both parties have gross income equal to the fair market value of what they received. A plumber who fixes an electrician’s pipes in exchange for rewiring work has income equal to the value of the electrical services. Business-related bartering goes on Schedule C; other bartering goes on Schedule 1. Organized barter exchanges report transactions on Form 1099-B.17Internal Revenue Service. Topic No. 420, Bartering Income
Cryptocurrency and Digital Assets
Digital assets follow the same principles as any other property under Section 61. Mining and staking rewards are gross income equal to the fair market value of the tokens at the moment you gain the ability to sell or transfer them. The IRS applied the Glenshaw Glass framework directly to proof-of-stake validation rewards in Revenue Ruling 2023-14.18Internal Revenue Service. Revenue Ruling 2023-14
Airdrops received after a hard fork are similarly taxable at fair market value when you gain dominion and control over the new tokens. Selling or exchanging cryptocurrency triggers capital gain or loss, just like selling stock. Form 1040 asks a direct yes-or-no question about digital asset activity, and every transaction must be reported.19Internal Revenue Service. Frequently Asked Questions on Virtual Currency Transactions20Internal Revenue Service. Digital Assets
Canceled Debt
When a lender forgives all or part of what you owe, the canceled amount is generally gross income. The logic: you borrowed money you had to repay, and now that obligation is gone, so your net worth went up. Lenders report cancellations of $600 or more on Form 1099-C.21Internal Revenue Service. About Form 1099-C, Cancellation of Debt
Section 108 carves out several situations where canceled debt is not income:
- Debt discharged in a Title 11 bankruptcy case.
- Debt canceled while you are insolvent, up to the extent of the insolvency.
- Qualified farm debt for eligible farmers.
- Qualified real property business debt for taxpayers other than C corporations.
- Qualified principal residence debt discharged before January 1, 2026, or under a written arrangement entered into before that date.
These exceptions are claimed on Form 982.22Office of the Law Revision Counsel. 26 U.S. Code 108 – Income from Discharge of Indebtedness
Student Loan Forgiveness in 2026
This one catches borrowers off guard. The American Rescue Plan Act temporarily excluded most forgiven student loan debt from gross income, but that exclusion applied only to forgiveness occurring between January 1, 2021 and December 31, 2025. Starting in 2026, forgiveness of a federal student loan balance under an income-driven repayment plan is generally treated as taxable cancellation of debt income.23Taxpayer Advocate Service. What to Know about Student Loan Forgiveness and Your Taxes
Some types of forgiveness remain permanently excluded. Public Service Loan Forgiveness, Teacher Loan Forgiveness, and discharges due to death or total and permanent disability do not create a tax liability. The Section 108 insolvency exception is also still available: if your debts exceed your assets when the forgiveness occurs, you can exclude some or all of the amount by filing Form 982.22Office of the Law Revision Counsel. 26 U.S. Code 108 – Income from Discharge of Indebtedness
Legal Settlements and Damages
Whether a settlement or judgment is gross income depends almost entirely on what the payment compensates. Damages received on account of personal physical injuries or physical sickness are excluded. This covers compensatory damages for medical bills, pain and suffering, and lost wages, provided the underlying claim involves an actual physical injury. It applies whether the money comes from a verdict or a settlement, lump sum or periodic payments.24Office of the Law Revision Counsel. 26 U.S. Code 104 – Compensation for Injuries or Sickness
Punitive damages are almost always taxable, even alongside an otherwise tax-free physical injury award. Emotional distress by itself is not a physical injury for purposes of this exclusion, so damages for employment discrimination, defamation, or harassment without any physical injury are fully taxable. Emotional distress damages are excluded only when they flow directly from an underlying physical injury, such as anxiety and sleeplessness caused by car accident injuries. Medical expenses you actually paid to treat emotional distress symptoms can be excluded up to the amount paid.24Office of the Law Revision Counsel. 26 U.S. Code 104 – Compensation for Injuries or Sickness
Back pay in employment cases is treated as wages in the year paid, reported on Form W-2, and subject to employment taxes.25Internal Revenue Service. Publication 957, Reporting Back Pay and Special Wage Payments to the Social Security Administration
What Section 61 Leaves Out
The default is that everything is taxable, but Congress has enacted dozens of specific exclusions scattered across the Code. The ones you are most likely to encounter:
Gifts and Inheritances
Property received as a gift or inheritance is not included in your gross income. The exclusion recognizes that the wealth has typically already been taxed at the donor or estate level. Income generated by the gifted or inherited property after the transfer is fully taxable, however. Inheriting a bond portfolio is tax-free; the interest those bonds pay you going forward is gross income.26Office of the Law Revision Counsel. 26 U.S. Code 102 – Gifts and Inheritances For tax purposes, a gift requires detached and disinterested generosity. A payment from an employer to an employee is never a gift, even if the employer calls it one. It is compensation.
Life Insurance Proceeds
Amounts paid under a life insurance contract because the insured died are excluded from the beneficiary’s gross income, whether paid in a lump sum or installments. If the policy was transferred for valuable consideration before the insured’s death, the exclusion may be limited. Interest earned on proceeds left on deposit with the insurance company is taxable.27Office of the Law Revision Counsel. 26 U.S. Code 101 – Certain Death Benefits
Municipal Bond Interest
Interest on bonds issued by a state, territory, or local government is excluded from federal gross income. State income tax may still apply, depending on the issuer and your state of residence. Interest on certain private activity bonds does not qualify unless specific statutory requirements are met.28Office of the Law Revision Counsel. 26 U.S. Code 103 – Interest on State and Local Bonds
Employer Health Coverage and Fringe Benefits
Certain non-cash benefits from your employer are excluded. The most significant is employer-provided health coverage: both the employer’s contributions toward your premiums and the value of the coverage are excluded. Other excluded fringe benefits include occasional meals, business use of a company vehicle, and qualified transportation benefits up to annual IRS limits.29Office of the Law Revision Counsel. 26 U.S. Code 132 – Certain Fringe Benefits
Qualified Scholarships
Scholarship and fellowship funds used for tuition, required fees, books, supplies, and equipment are excluded. Amounts used for room and board are not, and must be reported as income. The exclusion applies only to degree-seeking students at institutions with a regular faculty and curriculum.30Office of the Law Revision Counsel. 26 U.S. Code 117 – Qualified Scholarships
Disaster Relief, Foreign Earnings, and Combat Pay
Amounts received to reimburse personal, family, living, or funeral expenses caused by a federally declared disaster are excluded, as long as insurance did not already cover the expense.31Office of the Law Revision Counsel. 26 U.S. Code 139 – Disaster Relief Payments
U.S. citizens and residents living and working abroad who meet either the bona fide residence test or the physical presence test can exclude up to $132,900 of foreign earned income for tax year 2026.32Internal Revenue Service. Figuring the Foreign Earned Income Exclusion
Enlisted military personnel can exclude active-duty pay earned in a designated combat zone, along with hostile fire pay and certain reenlistment bonuses. Commissioned officers face a monthly cap.
When Income Has to Be Reported
Knowing something is gross income does not tell you which year to report it. That depends on your accounting method and a couple of related doctrines.
Cash Method Versus Accrual Method
Most individuals use the cash method: you report income in the year you actually or constructively receive it. The accrual method, used mainly by larger businesses, recognizes income when you have a fixed right to receive payment, even if the cash has not arrived. The cash method is simpler and generally defers tax until money is in hand.
Constructive Receipt
You cannot avoid tax by declining to pick up your paycheck. Income counts as received when it is credited to your account or otherwise made available to you without substantial restrictions. A check your employer issues on December 31 is taxable in December, even if you wait until January to cash it. The question is whether you had the ability to access the funds, not whether you exercised it.
Claim of Right
If you receive money under a claim of right, treating it as yours and spending it without restriction, you include it in gross income for that year, even if there is some chance you will have to give it back later. Disputed bonuses and advance payments often trigger this rule. If you do return the money in a later year, you take a deduction or credit at that point rather than amending the original return.
