The core rule: income form does not control taxability
Gross income analysis starts with the taxpayer's accession to wealth, not the payment method.
Cash, digital payments, property, services, and business credits can all create taxable income unless a specific exclusion applies. Lack of an information return may make income harder to detect, but it does not make the income nontaxable.
Cash receipts are still business income
The exam trap is the phrase "no paper trail." For federal income tax, that is not a rule. If a taxpayer performs services or sells goods in a business, cash receipts are part of gross receipts.
Original example
Alder Creek Detailers cleans vehicles and receives `18,600` by card, `7,900` by check, and `5,400` in cash. Only the card processor sends an information return.
The correct Schedule C starting point is not `18,600`. The business must include the cash and check receipts too, then separately deduct ordinary and necessary business expenses.
Practitioner frame
An enrolled practitioner should not advise a client to omit cash sales. For EA exam purposes, separate two questions:
- What must the taxpayer report?
- What conduct is expected from the practitioner?
The substantive answer is that business receipts do not disappear because they were paid in cash. The practitioner answer is that federal tax practice includes diligence, accuracy, and ethical constraints under Circular 230.
Barter can be income even without money
Barter analysis asks whether the taxpayer received goods or services in exchange for goods or services. If the exchange is taxable, the measure is generally fair market value.
Business barter example
Ridgeview Bookkeeping prepares quarterly books for Oak Lantern Studio. Oak Lantern gives Ridgeview a custom conference table worth `1,250` instead of paying cash.
Ridgeview has business income measured by the fair value of the table. Oak Lantern may also have its own reporting consequences based on what it gave and received.
Informal service swaps need a different first question
Not every neighborly favor should be forced into a business-barter model. A noncommercial reciprocal arrangement among friends, with no business, price list, enforceable account balance, or commercial exchange, may not be the same thing as a taxable barter transaction.
The EA habit is to identify the transaction before measuring it:
- Was there a business or profit-seeking activity?
- Did the parties agree to exchange services with a measurable value?
- Was there a barter exchange or organized credit system?
- Are the services similar, informal, and noncommercial?
- Is a form required, and does the taxpayer still have income without a form?
A child's earned income is not automatically the parents' income
Dependency status and income ownership are separate. A child may still be a dependent while having their own earned income.
Original example
Mason, age 13, repairs bicycles in the neighborhood and earns `2,850` of net profit after buying parts and tools. His parents still provide most of his support.
Mason's business profit is not simply added to his parents' wages. The filing question belongs to Mason. If he is required to file and cannot file for himself, a parent or guardian may have to help file a return for him.
Earned income versus unearned income
The result can differ for:
- wages
- self-employment income
- interest and dividends
- capital gains
- trust distributions
This packet focuses on earned income and self-employment income. Unearned income of children can trigger separate rules and should not be solved by the same shortcut.
Schedule C and Schedule SE placement
For an individual sole proprietor, business gross receipts generally flow to Schedule C. Net earnings from self-employment may trigger Schedule SE.
Fresh example
Sofia runs a weekend calligraphy business. During the year, she receives:
- `4,200` through an online marketplace
- `1,100` in cash at school events
- `600` of design software in exchange for lettering a vendor booth
Her gross receipts analysis starts with all three streams. The barter item is not ignored because it was not cash. The cash is not ignored because no platform reported it.
Exam distractors to reject
Distractor 1: "No Form 1099 means no income"
Reject this. Information reporting is not the source of taxability.
Distractor 2: "Cash discounts are automatically tax-free"
Reject this. A lower price may be a business decision, but cash receipts from services or sales still count.
Distractor 3: "Barter is only taxable when a barter exchange files a form"
Reject this. A form may help identify the transaction, but taxable barter can exist without a third-party form.
Distractor 4: "A dependent child's profit belongs on the parents' return"
Reject this for earned income. The child's income may create the child's own filing obligation even if the parents still claim the child as a dependent.
Exam takeaway
For EA questions, identify the earner, the form of payment, and the reporting channel. Visibility, convenience, and lack of a tax form are not exclusions from gross income.
