Gross Income Inclusions and Exclusions: CPA REG Notes [2026 Guide]

Gross income inclusions exclusions follow one starting rule in CPA REG: Section 61 of the Internal Revenue Code counts all income from whatever source derived, and a receipt stays out of gross income only when a specific Code section excludes it. Wages, interest, dividends, unemployment compensation, and canceled debt are in. Gifts, inheritances, municipal bond interest, and life insurance death proceeds are out. REG questions hand you a mixed list of receipts and test whether you can sort each item fast and name the section that controls it.

The stakes are high because this sorting skill opens almost every individual tax question. According to the AICPA CPA Exam Blueprints, federal taxation of individuals carries 22 to 32 percent of REG, the second largest area on the section. A candidate who classifies receipts correctly earns points here and also sets up the adjusted gross income work that follows.

Gross Income Inclusions Exclusions: The Section 61 Rule

Gross income inclusions exclusions start with one rule: Section 61 counts all income from any source unless a specific Code section excludes it. Wages, interest, dividends, and canceled debt go in. Gifts, inheritances, municipal bond interest, and life insurance death proceeds stay out.

Section 61(a) lists 15 items, and the list opens with the words “including (but not limited to).” That phrase does heavy lifting on the exam. An unlisted receipt still counts as gross income when it fits the general definition, which courts describe as an accession to wealth that the taxpayer clearly realizes and controls completely. Prizes, awards, found property, and illegal income all qualify under that definition, even though no line of Section 61(a) names them.

The 15 listed items are:

• Compensation for services, including fees, commissions, and fringe benefits
• Gross income derived from business
• Gains derived from dealings in property
• Interest
• Rents
• Royalties
• Dividends
• Alimony and separate maintenance payments (pre-2019 agreements)
• Annuities
• Income from life insurance and endowment contracts
• Pensions
• Income from discharge of indebtedness
• Distributive share of partnership income
• Income in respect of a decedent
• Income from an interest in an estate or trust

Notice the order of analysis this creates. First, ask whether the receipt is income at all. A return of capital is not income, and neither is borrowed money, because the borrower must repay it. Next, ask whether a specific section in Sections 101 through 140 excludes the item. Only then do you include it. IRS Publication 525, Taxable and Nontaxable Income, walks through this same order, and REG follows it closely.

The Exclusion Side: Sections 101 Through 140

Exclusions are narrow by design. Congress grants each one for a specific policy reason, and each one carries conditions. A REG question usually tests the condition, not the headline rule, so learn the limit that travels with every exclusion below.

Gifts and Inheritances: Section 102

Section 102(a) excludes the value of property a taxpayer acquires by gift, bequest, devise, or inheritance. The recipient pays no tax on the transfer itself, no matter how large it is. However, income that the transferred property produces later is taxable in the normal way, so dividends on inherited stock count as income. Section 102(c) adds a trap: a transfer from an employer to an employee is compensation, not a gift, even when the employer calls it one.

Life Insurance Proceeds: Section 101

Section 101(a) excludes life insurance proceeds paid because the insured person died. The beneficiary reports nothing, whether the insurer pays a lump sum or installments. By contrast, any interest the insurer pays on top of the death benefit is taxable interest, and surrendering a policy for more than the premiums paid creates taxable income on the excess.

Municipal Bond Interest: Section 103

Section 103 excludes interest on bonds issued by a state or local government. The exclusion supports state and local borrowing, and it applies only to the interest, never to gain on selling the bond. Tax-exempt interest still appears on Form 1040 as an information item, even though it adds nothing to taxable income.

Workers Compensation and Personal Injury Awards: Section 104

Section 104(a)(1) excludes workers compensation paid for occupational injury or sickness. Section 104(a)(2) excludes damages received on account of personal physical injuries or physical sickness, so a settlement for a broken leg stays out of gross income. Punitive damages, on the other hand, are taxable, with one narrow exception for punitive damages in a wrongful death action where state law provides only punitive damages. Damages for emotional distress without a physical injury are also taxable, apart from reimbursement of medical care costs.

Health Coverage, Scholarships, and Lodging: Sections 106, 117, and 119

Section 106 excludes employer-provided health coverage, including premiums the employer pays. Section 117 excludes a qualified scholarship for a degree candidate, but only the part that pays tuition and required fees, books, supplies, and equipment. Amounts for room, board, and travel are taxable, and so is any amount the student receives as pay for teaching or research services. Section 119 excludes meals and lodging that an employer provides on the business premises for the convenience of the employer; lodging must also be a condition of employment.

Gain on a Principal Residence: Section 121

Section 121 excludes gain on the sale of a principal residence up to $250,000 for a single filer and $500,000 for a married couple filing jointly. The seller must have owned the home and used it as a main home for at least two of the five years before the sale, and the exclusion is generally available only once every two years. Gain above the cap is taxable. IRS Publication 523, Selling Your Home, sets out the ownership and use tests in full.

Alimony and Child Support: The Agreement Date Decides

Divorce payments cause more REG errors than any other item in this topic, because the answer depends on a date. Under the Tax Cuts and Jobs Act, alimony under a divorce or separation agreement executed after December 31, 2018 is not income to the recipient and is not deductible by the payer. The payment is tax-neutral, like a gift between the two former spouses.

Agreements executed before 2019 keep the old rule instead: the recipient includes the alimony in gross income and the payer deducts it. That treatment survives unless a later modification expressly states that the new rule applies. As IRS Topic No. 452 confirms, a modification that stays silent on the point leaves the original treatment in place.

Child support is simpler, and the rule never changes. Child support is never income to the recipient and never deductible by the payer, regardless of when the agreement was signed. One practical detail matters when payments fall short: the payer’s money applies to child support first, and only the remainder counts as alimony.

Gross Income Inclusions Exclusions in Practice: A Worked Example

Megan, a single filer, had an eventful 2026. She received 12 different receipts during the year, listed in the table below. Her task, and the task on many REG questions, is to sort each receipt and total only the includable items. Megan owned and lived in her home for four of the last five years, and her divorce agreement was executed in 2024. She was solvent all year and was never in bankruptcy.

Receipt	Amount	Treatment	Section
Salary from employer	$92,000	Include	61
Interest on savings account	$1,850	Include	61
Dividends on stock	$2,400	Include	61
Unemployment compensation	$3,200	Include	85
Student loan balance discharged	$6,000	Include	61
Interest on municipal bonds	$1,100	Exclude	103
Cash gift from her father	$15,000	Exclude	102
Inheritance from her aunt	$40,000	Exclude	102
Child support received	$9,600	Exclude	Never income
Alimony, 2024 agreement	$12,000	Exclude	Post-2018 rule
Life insurance proceeds, father’s death	$100,000	Exclude	101
Gain on sale of her main home	$180,000	Exclude	121
Gross income	$105,450

The includable items total $105,450: $92,000 plus $1,850 plus $2,400 plus $3,200 plus $6,000. The excluded items total $357,700, so Megan received $463,150 during the year yet reports gross income of only $105,450. Two items deserve a second look. First, the discharged student loan counts because Megan was solvent and outside bankruptcy, and, as IRS Topic No. 431 explains, the temporary exclusion for student loan discharges applied only to discharges before January 1, 2026. Second, the $180,000 home gain fits under Megan’s $250,000 Section 121 cap, so Section 121 removes all of it.

Traps That Cost REG Points

• Punitive damages. Compensatory damages for a physical injury are excluded under Section 104(a)(2), but punitive damages are taxable, apart from the narrow wrongful death exception.
• Scholarship room and board. Section 117 protects tuition and required course costs only. Money a scholarship provides for room, board, or travel is taxable.
• Employer gifts. A bonus or gift card from an employer is wages under Section 102(c), whatever the employer calls it.
• Forgiven debt. Discharge of indebtedness is gross income under Section 61. Only the bankruptcy and insolvency exclusions in Section 108 remove it, and this trap catches candidates every exam window.
• The alimony date. The same $12,000 payment is income under a 2017 agreement and tax-neutral under a 2024 agreement. Always read the agreement date before you classify.
• Gain above the Section 121 cap. Section 121 shelters the first $250,000 or $500,000 of gain. The excess is taxable capital gain, not excluded income.

Frequently Asked Questions

Is a cash gift from a parent taxable income?

No. Section 102(a) excludes gifts from the recipient’s gross income, with no dollar cap on the exclusion. Any gift tax exposure falls on the donor, not the recipient. Income the gifted money earns later, such as bank interest, is taxable as usual.

Is alimony taxable income in 2026?

It depends on the agreement date. Alimony under an agreement executed after December 31, 2018 is not income to the recipient and not deductible by the payer. Alimony under an earlier agreement remains income to the recipient and a deduction for the payer, unless a modification expressly adopts the new rule.

Are life insurance proceeds taxable?

Proceeds paid because the insured person died are excluded under Section 101(a). Interest the insurer pays on those proceeds is taxable, and gain on surrendering a policy during the insured person’s lifetime is taxable to the extent it exceeds premiums paid.

Is canceled student loan debt taxable income?

Generally, yes. Discharge of indebtedness is gross income under Section 61, and the temporary exclusion for student loan discharges covered only discharges before January 1, 2026. Debt discharged in a bankruptcy case, or to the extent the taxpayer is insolvent, stays excluded under Section 108.

How much home sale gain can a single filer exclude?

A single filer can exclude up to $250,000 of gain under Section 121, and a married couple filing jointly can exclude up to $500,000. The seller must meet the ownership and use tests: two of the five years before the sale in each case. Gain above the cap is taxable.
