The regulation provides an example of activities where deductions are not allowable under section 162 or 212. These are activities carried on primarily as a sport, hobby, or for recreation. Legal Information Institute This definition helps distinguish between a business and a personal pursuit. If the client’s side activity fits this description, it may not belong on a business schedule.

The Internal Revenue Code provides a specific definition for activities that do not meet the threshold for business treatment. Under 26 U.S. Code § 183, the term “activity not engaged in for profit” means any activity other than one with respect to which deductions are allowable for the taxable year under section 162 or under paragraph (1) or (2) of section 212, according to Legal Information Institute. This definition sets the boundary between deductible business expenses and non-deductible personal or hobby expenses. If an activity falls outside the scope of section 162 or section 212 paragraphs (1) and (2), it is classified as an activity not engaged in for profit.

When evaluating whether a client’s side activity fits this definition, the focus shifts from the taxpayer’s personal belief to documented behavior. This standard requires the operations lead to look beyond verbal assurances of profit motive. Instead, the determination relies on tangible evidence of how the activity is conducted.

The Internal Revenue Code provides a specific safe harbor for determining if an activity is engaged in for profit. Under 26 U.S. Code § 183, if the gross income derived from an activity for 3 or more of the taxable years in the period of 5 consecutive taxable years which ends with the taxable year exceeds the deductions attributable to such activity, the activity is presumed to be engaged in for profit, unless the Secretary establishes to the contrary, according to Legal Information Institute. This presumption applies for purposes of the tax chapter to the specific taxable year in question. The statute calculates this by looking at whether income exceeds deductions, determined without regard to whether or not such activity is engaged in for profit, according to Legal Information Institute.

For activities involving horses, the statute modifies these year counts. In the case of an activity which consists in major part of the breeding, training, showing, or racing of horses, the preceding sentence shall be applied by substituting “2” for “3” and “7” for “5,” according to Legal Information Institute. This means a horse activity is presumed for profit if it shows a profit in 2 or more of the 7 consecutive taxable years ending with the current year.

A side activity, with every amount labelled illustrative, is checked over 5 years. Income and deductions are 580 and 420, then 420 and 580, then 835 and 580, then 190 and 420, then 840 and 580. Income exceeds deductions in 3 of the 5 years. That is the comparison used for the three-of-five-year presumption described above. An activity that consists in major part of breeding, training, showing, or racing horses would instead be checked for profit in 2 years out of 7. These amounts are illustrative only and stand for no real client.

When you review a client's side activity, the regulation outlines how specific behaviors signal profit motive. The fact that the taxpayer carries on the activity in a businesslike manner and maintains complete and accurate books and records may indicate that the activity is engaged in for profit, according to Legal Information Institute. This standard suggests that organized documentation is a key indicator. If the client keeps books that mirror standard business practices, that structure supports the argument for a profit motive.

Professional preparation also plays a role in the determination. Preparation for the activity by extensive study of its accepted business, economic, and scientific practices, or consultation with those who are expert therein, may indicate that the taxpayer has a profit motive where the taxpayer carries on the activity in accordance with such practices, according to Legal Information Institute. This covers clients who have researched industry standards or hired specialists to guide their operations. If the client follows accepted practices in their field, that alignment with professional norms supports the profit-motive claim.

Time commitment is another factor, but it is not the sole measure. The fact that the taxpayer devotes a limited amount of time to an activity does not necessarily indicate a lack of profit motive where the taxpayer employs competent and qualified persons to carry on such activity, according to Legal Information Institute. This means a client who hires staff to run the day-to-day operations can still demonstrate a profit motive even if they spend few hours personally on the task. The presence of competent and qualified persons carrying on the activity offsets the limited personal time.

The table below traces the specific profit factors and safe-harbor rules to their named sources. Each row isolates a single publisher's quoted language so you can verify the exact wording during intake.

Use the Internal Revenue Service rows to check if your client keeps records in a businesslike manner and if they rely on the income for their livelihood. The Journal of Accountancy row confirms that the regulation lists nine factors for the profit determination. The Tax Adviser row provides the specific year counts for the safe harbor, distinguishing between general activities and those involving horses. Verify these quotes against the linked pages before finalizing your intake notes.

Use the nine profit factors to structure your intake questions. Each question below maps to a specific factor so you can document the client's answer and the supporting papers they have.

Do you keep complete and accurate books and records?

Ask whether the client carries on the activity in a businesslike manner and maintains complete and accurate books and records, according to Internal Revenue Service. If the client uses a separate bank account, tracks expenses in accounting software, or keeps papers in a dedicated folder, note that documentation and compare it with a client bank reconciliation. If they do not, ask what records they currently keep and whether they can reconstruct past transactions using missing client records.

Do you depend on income from the activity for your livelihood?

Ask whether the client depends on income from the activity for their livelihood, according to Internal Revenue Service. This question helps distinguish a primary income source from a casual side project. If the client earns a full-time wage elsewhere and the side activity generates only modest income, that context matters for the profit-motive analysis.

Are your losses due to circumstances beyond your control?

Ask whether the client's losses are due to circumstances beyond their control or are normal in the startup phase of their type of business, according to Internal Revenue Service. If losses persist beyond the startup phase without a clear external cause, flag that for further review.

What other factors do you have papers for?

Beyond the three questions above, ask the client to list which of the remaining profit factors they already have documentation for. This inventory becomes the first page of your intake file and tells you exactly what to request before you open the business schedule.

On the next side-activity intake, write down which of the nine factors you already have papers for and which ones you still need to ask about. Pair that list with the Accounting Client Intake Checklist for a Clear Handoff.

What are the nine factors for?

The regulation lists nine factors to determine whether a taxpayer engages in an activity for profit, according to the Journal of Accountancy.

Can one factor decide the file?

No, the regulation explicitly states that no one factor is determinative in making this determination, according to the Legal Information Institute.

What does the three-of-five-year presumption do?

If gross income exceeds deductions in three or more of the five consecutive taxable years ending with the current year, the activity is presumed to be engaged in for profit unless the Secretary establishes the contrary, according to the Legal Information Institute.

How are horses different?

For activities consisting in major part of breeding, training, showing, or racing horses, the statute substitutes “2” for “3” and “7” for “5” in the safe harbor calculation, according to the Legal Information Institute.

What should I ask before opening the business schedule?

Ask whether the client maintains businesslike records and whether they depend on the activity for their livelihood. Inquire if losses are due to circumstances beyond the client's control or if the activity is in a startup phase.
