Income Not Subject to Tax Is Called Nontaxable Income

Income the federal government doesn’t tax is called nontaxable income, and the tax code names the specific categories that qualify: gifts and inheritances, life insurance death benefits, most of the gain on a home sale, certain employer-paid benefits, qualifying scholarships, most need-based government aid, child support, workers’ compensation, municipal bond interest, damages for physical injury, and qualified Roth retirement distributions. Everything else is presumed taxable until you can point to a provision that says otherwise.

Why the Default Is “Taxable”

Federal law starts with the broadest possible net. Gross income includes all income from whatever source, and the statutory list of examples is explicitly open-ended.¹ Unless a specific provision removes a category of money from that definition, the IRS treats it as taxable.

An exclusion works differently from a deduction. Excluded income never enters your gross income in the first place, so you don’t add it and then subtract it. That mechanical difference matters when you fill out a return, and it matters even more if you get the classification wrong. Underreporting because you treated taxable money as excluded triggers an accuracy-related penalty of 20% of the underpayment.²

Gifts and Inheritances

Money or property you receive as a gift or an inheritance is excluded from your gross income.³ A relative can hand you $50,000 in cash or leave you a house worth $400,000, and neither counts as taxable income to you. Any gift or estate tax falls on the giver or the estate, not on you.

Inherited property also gets a reset in basis: for capital gains purposes, its cost basis becomes the fair market value on the date of death.⁴ One important limit: while the property itself is excluded, income it produces afterward is taxable. Rent from an inherited house, dividends from inherited stock, and interest from an inherited bank account all land on your return like any other income.

Life Insurance Death Benefits

When a beneficiary receives a life insurance payout because the insured person died, that amount is excluded from gross income.⁵ A $500,000 death benefit arrives tax-free whether it comes as a lump sum or in installments.

The exclusion covers the benefit itself, not money that grows on top of it. If you leave the proceeds with the insurer and they pay interest on the balance, that interest is taxable.⁵ That most often shows up when a beneficiary chooses an installment option instead of taking the full amount at once.

Gain on Selling Your Home

Selling your primary residence can generate a substantial gain that’s entirely excluded. Single filers can exclude up to $250,000 of profit; married couples filing jointly can exclude up to $500,000.⁶ For most homeowners, that shelters the entire profit.

To qualify, you must have owned the home for at least two of the five years before the sale and used it as your main residence for at least two of those five years.⁶ The two years don’t need to be consecutive. For the joint $500,000 exclusion, both spouses must meet the use requirement, though only one needs to meet the ownership requirement. You can claim the exclusion more than once in a lifetime, but not more often than every two years. And it applies only to gain: a loss on a personal residence isn’t deductible.

Employer-Provided Benefits

Several workplace benefits that feel like compensation are specifically excluded. The biggest is employer-paid health insurance: when your employer covers your premiums, that coverage doesn’t count as income to you.⁷ For most working people, it’s the largest exclusion they receive.

Employer-provided group-term life insurance is excluded up to $50,000 of coverage. If your employer provides more, the cost of the excess shows up on your W-2 as imputed income, calculated using IRS age-based cost tables.⁸

Employer-funded education assistance is excluded up to $5,250 per year, covering tuition, fees, books, supplies, and payments toward your student loans.⁹ Anything above that is taxable as regular wages.

Scholarships and Fellowship Grants

Scholarship money is excluded from gross income, but only when used for qualifying expenses at a degree-granting institution. Qualifying expenses are tuition, required fees, and required books, supplies, and equipment for your courses.¹⁰

Scholarship funds spent on room and board, travel, or optional equipment are taxable.¹¹ If you receive a $30,000 scholarship and tuition costs $22,000, the remaining $8,000 used for housing is taxable income even though you never see it as cash. Grants that pay you for services also lose their tax-free status: if the money requires you to teach or perform research as a condition of receiving it, that portion is treated as compensation.¹⁰

Government Benefits, Child Support, and Workers’ Comp

Most need-based government payments are excluded. Supplemental Security Income, welfare, and other public assistance benefits aren’t taxable. Federal disaster relief grants are also excluded so long as they cover necessary expenses like housing, medical care, and funeral costs.¹²

Child support is never taxable to the person receiving it and never deductible by the person paying it.¹³ The tax code treats it as a neutral transfer for the child’s benefit.

Workers’ compensation benefits for a job-related injury or illness are excluded from gross income.¹⁴ If you receive workers’ comp and Social Security disability at the same time, however, part of your Social Security benefits may become taxable depending on your total income.

Social Security Benefits

Social Security sits in its own category: not fully taxable, not fully excluded. What you owe depends on your combined income, which the IRS defines as your adjusted gross income plus any nontaxable interest plus half your Social Security benefits.

For single filers, Social Security stays completely tax-free if combined income is below $25,000. Between $25,000 and $34,000, up to 50% of benefits become taxable. Above $34,000, up to 85% is taxable. For married couples filing jointly, the thresholds are $32,000 and $44,000.¹⁵ SSI, by contrast, is always fully excluded regardless of other earnings.¹⁶

Disability Insurance Benefits

Whether disability insurance payments are taxable depends on who paid the premiums. If you paid the premiums yourself with after-tax dollars, the benefits are tax-free. If your employer paid, the benefits are fully taxable. When costs are split, the taxable portion matches the employer’s share.¹⁷

Watch for a trap: if you pay premiums through a cafeteria plan on a pre-tax basis, the IRS treats them as employer-paid because you never included them in your taxable income. That makes the future benefits fully taxable.¹⁷ Some employees deliberately elect after-tax premium payments to keep future benefits tax-free. Your pay stub will tell you which method your employer uses.

Municipal Bond Interest

Interest earned on bonds issued by state and local governments is excluded from federal income tax.¹⁸ Earn $5,000 in interest from a municipal bond fund and your federal tax bill doesn’t move.

You still have to report the amount on your return as an informational item. Reporting doesn’t convert it to taxable income, but the IRS uses the figure to calculate other things, particularly the taxable portion of Social Security benefits for retirees.¹⁹

Personal Injury Settlements

Damages received for a physical injury or physical sickness are excluded from gross income, whether the money comes from a lawsuit verdict or a negotiated settlement.¹⁴ A $150,000 settlement for a car accident injury, including amounts covering medical bills and lost wages, stays entirely out of taxable income.

The exclusion has hard boundaries. Punitive damages are always taxable, even when awarded alongside a physical injury claim.²⁰ Emotional distress damages are taxable unless the distress stems directly from a physical injury. If you were physically hurt and developed anxiety as a result, the emotional distress portion of your settlement is generally excluded too. Emotional distress from a non-physical wrong like defamation or harassment is taxable, and physical symptoms of stress such as headaches and insomnia don’t qualify as “physical injury” in the eyes of the IRS.¹⁴

Qualified Roth Distributions

Qualified distributions from a Roth IRA are completely excluded from gross income, including the earnings.²¹ The same rule applies to designated Roth accounts inside employer plans like 401(k)s.²² You pay tax on Roth contributions up front with after-tax dollars, and in return the account grows and pays out tax-free.

To qualify for tax-free treatment, the account has to have been open for at least five years, and you must be at least 59½, disabled, or deceased (for beneficiaries). Pull earnings before meeting those conditions and you’ll owe income tax plus a potential 10% early distribution penalty. Contributions you already paid tax on can always come back out tax-free, even if the five-year rule isn’t met.

What to Report Anyway

Excluded income isn’t always invisible to the IRS. Municipal bond interest goes on your return as an informational item, and the IRS uses it to figure how much of your Social Security is taxable.¹⁹ Leaving it off doesn’t save you any tax and can trigger a notice.

Scholarship funds that exceed qualified education expenses need to show up on the recipient’s return as income. Large gifts may require the donor to file a gift tax return, even though you as the recipient owe nothing. If you receive a legal settlement, keep clear documentation of what portion covers physical injury and what portion covers other claims, because the IRS looks closely at how settlements are allocated between taxable and nontaxable categories. The safest approach across the board is to keep records that connect each excluded item to the specific provision that protects it.
