1. What IRC 183 Does and Why It Matters Post-TCJA
IRC 183 Quick Reference
What it does: IRC 183 governs "activities not engaged in for profit." When the IRS determines that a taxpayer's activity is a hobby rather than a legitimate trade or business, IRC 183 disallows all deductions attributable to that activity -- except those allowable without regard to profit motive (such as mortgage interest or property taxes on property used in the activity). Gross income from the activity is still taxable in full.
Post-TCJA severity: Before the Tax Cuts and Jobs Act (TCJA, Pub. L. 115-97, 2017), a taxpayer subject to IRC 183 could still deduct hobby expenses up to the level of gross hobby income as a miscellaneous itemized deduction on Schedule A (subject to the 2% AGI floor under IRC 67). The TCJA suspended miscellaneous itemized deductions for tax years 2018 through 2025. The One Big Beautiful Bill Act (OBBBA, Pub. L. 119-21, July 4, 2025) did not restore the miscellaneous itemized deduction or create a new above-the-line deduction for hobby expenses (verify current treatment at IRS.gov). For affected tax years, IRC 183 disallowance is functionally absolute: gross hobby income is fully taxable and virtually no expenses offset it.
Not covered here: IRC 469 passive activity loss rules are a distinct limitation; the two analyses are separate and sequential. IRC 183 is applied first (does the activity have a profit motive at all?); IRC 469 is applied only to activities already accepted as profit-motivated (does the taxpayer materially participate?). See the Related Guides section for the IRC 469 guide.
1.1 The Core Mechanism
Under IRC 183(a) (hedge: verify at IRS.gov and in current IRC text), if an activity "is not engaged in for profit," the deductions attributable to that activity are limited to the amounts specified in IRC 183(b). Any deduction that would have been allowed as a business expense under IRC 162 but for the hobby-loss determination is permanently disallowed. There is no carryover; the disallowed amount does not offset future hobby income or any other income in a later year.
1.2 OBBBA: No Direct Amendment to IRC 183
OBBBA (Pub. L. 119-21, July 4, 2025) made no direct amendments to IRC 183. OBBBA's Schedule 1A above-the-line deduction structure (the non-itemizer charitable deduction, NCTI deductions, and related provisions) does not include a slot for hobby activity expenses. Practitioners should verify the current status of IRC 67 and the miscellaneous itemized deduction at IRS.gov to confirm whether any post-OBBBA guidance has altered this analysis.
2. The Trade-or-Business vs. Hobby Threshold
2.1 The Profit Objective Standard
Under IRC 183(a) (hedge: verify at IRS.gov and in current IRC text), an activity is "not engaged in for profit" if it is not a trade or business under IRC 162 and is not an activity engaged in for the production of income under IRC 212. The threshold question is whether the taxpayer carries on the activity with an "actual and honest objective of making a profit" (hedge to Treas. Reg. Section 1.183-2(a) and IRS.gov; verify current judicial interpretation).
2.2 Profit Objective vs. Actual Profit
The standard is the taxpayer's profit objective -- not whether the activity actually generates a profit. A taxpayer who operates a new business at a loss for several years while making genuine efforts toward profitability may satisfy the "for profit" standard even without positive net income. Conversely, a taxpayer who pursues a pleasurable activity and incidentally receives income may fail the standard even in profitable years if the facts show no genuine profit motive. Verify the current judicial interpretation of the profit objective standard at IRS.gov and through current legal research.
2.3 The Sequential Relationship with IRC 469
IRC 183 and IRC 469 address different questions at different analytical stages. IRC 183 asks: does the activity have a profit motive at all? If no, IRC 183 permanently disallows the losses (subject to the Tier 1 and Tier 2 allowances in IRC 183(b)). If yes, the activity is analyzed under IRC 469: does the taxpayer materially participate? If not, the losses are deferred to future passive income -- they are not permanently lost. An activity that fails IRC 183 does not reach the IRC 469 analysis. A loss deferred under IRC 469 can be used against future passive income or released on a fully taxable disposition; an IRC 183-disallowed loss cannot.
3. The Nine-Factor Test Under Treas. Reg. Section 1.183-2(b)
Warning: No Single Factor Is Determinative -- Address All Nine, Including Weak Ones
Under Treas. Reg. Section 1.183-2(b) (hedge: verify at IRS.gov and in current regulations), the nine factors are non-exclusive; no single factor controls the outcome. All relevant facts and circumstances must be weighed together. In practice, the IRS and the Tax Court often give significant negative weight to extended loss history, high non-activity income (which makes tax savings from losses valuable), and obvious elements of personal pleasure or recreation. A protest or litigation strategy that addresses only the favorable factors while ignoring adverse ones is substantially less persuasive than one that acknowledges weaknesses and contextualizes them. All nine factors must be addressed in every engagement involving a potential IRC 183 issue. Verify the current weight given to each factor at IRS.gov and through current legal research.
The following table summarizes all nine factors under Treas. Reg. Section 1.183-2(b) (hedge each factor to the current regulation and IRS.gov; all scenario examples are illustrative only and must be verified against the client's specific facts).
| Factor | Positive signals (supports business treatment) | Negative signals (supports hobby classification) | Practitioner notes (illustrative; verify at IRS.gov) |
|---|---|---|---|
| (1) Manner of carrying on the activity | Separate business bank account; formal books and records; written business plan; industry-standard accounting; strategic responses to losses | Commingled personal and activity funds; no formal books; no response to consecutive losses; personal assets mixed with activity assets | Often the most heavily weighted positive factor. IRS examiners assess whether the taxpayer operates with the same care as a profitable business in the same industry. Separate banking and contemporaneous books are minimum expectations. |
| (2) Expertise of the taxpayer or advisers | Formal training in the field; consultation with recognized industry experts; strategy changes based on expert advice | No training or expertise; ignoring expert recommendations; novice entry into a highly specialized activity | Documented expert consultations -- even where not fully followed -- strengthen this factor. Retain written records of all expert advice received and any resulting business decisions. |
| (3) Time and effort expended | Substantial personal time devoted to the activity; withdrawal from other employment; hiring qualified employees or managers | Minimal time; activity pursued only on weekends or vacations; primary employment unrelated to the activity | Contemporaneous time logs are the strongest evidence. Reconstructed logs are less persuasive. Document the nature of the business activities performed, not just hours. |
| (4) Expectation that assets may appreciate | Activity uses assets (land, horses, art, collectibles) with a genuine appreciation expectation independent of current income | Assets used primarily for personal enjoyment; no objective basis for appreciation; activity generates only depreciating consumables | Horse breeding and farming activities often rely on land appreciation to support this factor. The appreciation expectation must be objectively supportable. Any asset value figures used must be labeled "Illustrative Only." |
| (5) Success in other activities for profit | Prior track record of converting unprofitable activities into profitable ones; demonstrated business acumen in other ventures | No prior business experience; history of failed ventures with no course corrections | Prior success in any business -- not just the same activity -- can support this factor. Prior success in an unrelated industry demonstrates general business competence and profit-seeking behavior. |
| (6) History of income or losses | Losses in early start-up phase; losses attributable to unforeseen circumstances (drought, market shift); trend toward profitability | Extended loss history with no trend toward profit; losses continue despite claimed corrective actions; losses grow proportionally with the taxpayer's tax bracket | Extended losses are the IRS's primary examination trigger. Early-stage losses are less problematic than losses that persist 10-15 years. Document all external factors causing losses and all corrective responses taken. |
| (7) Occasional profits in relation to losses | Profits in some years, even if modest; profit-to-loss ratio consistent with a genuine start-up or cyclical business | No profitable years at all; profits, when they occur, are trivial relative to accumulated losses; profits arise only in years with significant tax benefit to the taxpayer | The IRS examines the ratio of profits to losses over the full period. A single profitable year in a decade of losses is less persuasive than an improving trend. Any dollar figures must be labeled "Illustrative Only." |
| (8) Financial status of the taxpayer | Activity is the taxpayer's primary or substantial income source; taxpayer cannot sustain activity losses indefinitely from unrelated income | Large, consistent non-activity income (salary, investment income) that makes tax savings from hobby losses highly valuable; activity losses provide substantial tax shelter | High-income taxpayers attract heightened IRS scrutiny. When activity losses produce large reductions in high-bracket tax liability, the IRS looks closely at whether losses primarily serve as a tax shelter. Particularly relevant for horse-breeding, aircraft, and collectibles activities. |
| (9) Elements of personal pleasure or recreation | Activity involves unpleasant tasks typical of legitimate businesses; efforts focus on income maximization rather than personal enjoyment | Obvious personal enjoyment (travel, competition, social aspects); assets available for personal use; activity takes place at vacation locations | Personal enjoyment alone does not disqualify an activity -- many legitimate businesses are enjoyable. But activities with strong recreational elements (yachting, wine-making, art collecting, horse racing) must present compelling evidence on the other eight factors. Document purely commercial aspects of the activity. |
4. The Profit Presumption Under IRC 183(d)
Caution: The Profit Presumption Is Rebuttable -- Meeting 3-of-5 Does Not Guarantee Business Treatment
Under IRC 183(d) (hedge: verify at IRS.gov and in current IRC text), the profit presumption shifts the burden of proof to the IRS, but the IRS may still rebut it with evidence that the activity lacks a genuine profit motive. A taxpayer who meets the three-of-five-year rule but has other overwhelmingly negative facts -- extensive personal use of activity assets, no businesslike records, very large non-activity income -- may still be classified as engaging in a hobby after the IRS presents its rebuttal. The presumption is a useful defensive tool but not an automatic safe harbor. Never advise a client that meeting the presumption eliminates IRC 183 risk. Verify the current rebuttal standards at IRS.gov and through current legal research.
4.1 The Three-of-Five-Year Rule
Under IRC 183(d) (hedge: verify at IRS.gov and in current IRC text), if an activity produces gross income that exceeds the deductions attributable to it in at least 3 of the 5 consecutive tax years ending with the tax year in question, the activity is presumed to be engaged in for profit. When the presumption applies, the IRS bears the burden of presenting evidence to rebut it. Verify the current operation of this presumption and the burden-shifting mechanics at IRS.gov.
4.2 The Horse-Breeding and Horse-Racing Exception
For activities involving breeding, training, showing, or racing horses, IRC 183(d) (hedge: verify at IRS.gov and in current IRC text) provides a modified presumption: the activity is presumed for profit if it is profitable in at least 2 of the 7 consecutive tax years ending with the tax year in question. This extended window reflects the longer typical start-up cycle for horse-related activities. Verify the current horse-activity presumption rule and what qualifies as a horse activity for this purpose at IRS.gov.
4.3 Year-by-Year Analysis
The presumption is applied separately for each tax year under examination, not as a permanent status once achieved. A taxpayer who met the presumption for tax year 2022 may not meet it for tax year 2024 if the activity was unprofitable in 2023 and 2024 and profitable in only two of the preceding five years. Practitioners must reanalyze the presumption for each year at issue. Verify the current year-by-year application methodology at IRS.gov.
5. The IRC 183(e) Election: Postponing the Profit-Motive Determination
Caution: The IRC 183(e) Election Extends the Assessment SOL -- Advise Clients of Multi-Year Exposure Before Electing
Under IRC 183(e) (hedge: verify at IRS.gov and in current IRC text; verify whether Rev. Proc. 2004-34 governing the election mechanics has been superseded or updated at IRS.gov), making the election to postpone the profit-motive determination also extends the statute of limitations for assessment under IRC 6501 for all years within the 5-year (or 7-year, for horse activities) period. If the activity ultimately fails the profit motive test when the period ends, the IRS may assess tax deficiencies for ALL years in the elected period -- including years that would otherwise be closed under the ordinary 3-year IRC 6501 assessment SOL. Advise clients explicitly of this multi-year exposure before recommending the election. The election is not appropriate for every taxpayer. Verify all IRC 183(e) election mechanics and the SOL interaction at IRS.gov before advising any client.
5.1 What the Election Does
Under IRC 183(e) (hedge: verify at IRS.gov and in current IRC text), a taxpayer who has not yet completed the 5-year (or 7-year) period needed for the profit presumption may elect to suspend the IRS's determination of whether the activity is engaged in for profit until the period ends. During the election period, the IRS cannot make a final hobby-loss determination. At the end of the period, the presumption either applies (if the taxpayer meets the profit threshold) or the nine-factor analysis proceeds on the full record.
5.2 Election Mechanics
Under IRC 183(e) and applicable procedures (hedge ALL specifics to Rev. Proc. 2004-34 and IRS.gov; verify whether Rev. Proc. 2004-34 has been superseded), the election must generally be filed by the due date of the return (including extensions) for the second tax year in which the taxpayer engages in the activity. The election is made by attaching a statement to the return. Missing the filing deadline forfeits the election. Verify all current election requirements, the filing deadline, and any available late-election relief at IRS.gov before advising any client.
5.3 When NOT to Elect
The election is not appropriate when: (a) the activity is unlikely to meet the profit presumption even with more time; (b) the client prefers certainty over extended SOL exposure; or (c) the multi-year SOL exposure represents a greater tax risk than the current deficiency exposure on a single year. Verify all strategic considerations at IRS.gov before making or recommending this election.
6. Deductions Allowed Under IRC 183(b): The Ordering Rules
6.1 The Two-Tier Structure
Under IRC 183(b) (hedge: verify at IRS.gov and in current IRC text), even when an activity is classified as a hobby, two tiers of deductions may survive:
- Tier 1 (IRC 183(b)(1)): Deductions allowable even without any trade-or-business or profit requirement -- primarily mortgage interest under IRC 163 and state and local property taxes under IRC 164 attributable to property used in the activity. These are deducted first, in full, regardless of hobby income.
- Tier 2 (IRC 183(b)(2)): Deductions that would be allowable if the activity were a trade or business (such as business expenses under IRC 162), but ONLY to the extent that gross hobby income exceeds the Tier 1 deductions. Tier 2 deductions may reduce gross hobby income to zero but may not create a loss.
6.2 Post-TCJA Impact on Tier 2
Pre-TCJA, Tier 2 deductions were potentially recoverable as miscellaneous itemized deductions on Schedule A (subject to the 2% AGI floor). Post-TCJA, the miscellaneous itemized deduction is suspended (verify whether OBBBA or subsequent legislation restored it at IRS.gov). For most taxpayers in most post-TCJA years, Tier 2 deductions are effectively unavailable as a practical offset: they can reduce hobby income to zero within the activity but produce no deduction that offsets non-hobby income. Verify the current status of miscellaneous itemized deductions at IRS.gov.
6.3 Gross Hobby Income Is Fully Taxable
Gross income from a hobby activity -- sales, fees, prizes, or other receipts -- must be reported in full as gross income on the return under IRC 61 (hedge to current IRS.gov guidance). Post-TCJA, the taxpayer pays tax on all gross hobby income with almost no deduction to offset it. Practitioners must explain this asymmetric outcome clearly before a client makes any decision about whether to accept or contest an IRC 183 determination.
7. Post-TCJA Impact: Why IRC 183 Disallowance Is Now Absolute
Warning: Post-TCJA, Hobby Expenses Are Not Deductible on Schedule A -- Verify Current Law at IRS.gov Before Advising Any Client
Pre-TCJA, a taxpayer subject to IRC 183 could still deduct hobby expenses up to gross hobby income as a miscellaneous itemized deduction on Schedule A (subject to the 2% AGI floor under IRC 67). The TCJA suspended miscellaneous itemized deductions for tax years 2018 through 2025. OBBBA did not restore the miscellaneous itemized deduction or create a new above-the-line slot for hobby expenses (verify at IRS.gov). For tax years in which the suspension applies, an IRC 183 determination means gross hobby income is fully taxable with virtually no offsetting deduction. The tax cost of hobby classification is materially higher post-TCJA than it was before 2018. Verify the current status of the miscellaneous itemized deduction at IRS.gov before advising any client on the expected cost of an IRC 183 determination -- and before advising a client whether to accept or contest one.
7.1 The Pre-TCJA Framework
Before TCJA, a taxpayer classified as engaging in a hobby could deduct hobby-related expenses up to the level of gross hobby income as a miscellaneous itemized deduction on Schedule A, subject to the 2% of adjusted gross income floor under IRC 67. The deduction was imperfect -- many clients did not itemize, and the 2% floor reduced the benefit -- but it substantially reduced the after-tax cost of an adverse IRC 183 determination.
7.2 The Post-TCJA Landscape
TCJA suspended miscellaneous itemized deductions for tax years beginning after December 31, 2017, and before January 1, 2026 (verify the precise effective dates and any OBBBA or legislative modifications to the TCJA sunset at IRS.gov). For years in which the suspension applies, an IRC 183-classified taxpayer pays income tax on all gross hobby income while deducting almost nothing against it. OBBBA's above-the-line deduction expansions (Schedule 1A, non-itemizer charitable, NCTI) do not include a slot for hobby expenses. Verify current law at IRS.gov.
7.3 Practitioner Implication: The Stakes Have Increased
Practitioners should explain to clients with recurring-loss activities that the post-TCJA tax cost of a hobby determination is materially higher than pre-TCJA. This changes the cost-benefit analysis for contesting IRC 183 at Appeals or Tax Court (the cost of litigation may be worthwhile where pre-TCJA it might not have been), and it makes early, proactive documentation of profit motive more valuable. A client who might have accepted a hobby determination pre-TCJA and taken the Schedule A deduction may now have strong financial reasons to contest it through all available channels.
8. IRS Audit Patterns: What Triggers an IRC 183 Examination
8.1 Common Examination Triggers
Based on IRS examination guidance and publicly available IRS data (hedge all descriptions to current IRM, IRS Data Book, and IRS.gov; IRS examination priorities change; verify current priorities at IRS.gov), the following fact patterns most commonly trigger IRC 183 scrutiny:
- Consecutive Schedule C losses: Three or more consecutive years of net losses on Schedule C, Schedule E, or Schedule F are the most common trigger. The IRS's automated systems identify recurring-loss patterns in certain industry codes.
- High-income taxpayers with large activity losses: When a taxpayer with significant other income (wages, investment income, or other businesses) also claims large losses from a separate activity, the combination draws examination interest. Factor (8) (financial status) is directly implicated.
- Specific activity categories: Horse breeding and racing, yacht operation, aircraft operation, art and collectibles dealing, wine production, photography, and farming activities with recreational characteristics are perennially high-examination activity types.
- Gig economy and online business losses: The IRS has increased examination activity in the online content creator, short-term rental platform, and gig-economy loss space in recent years (hedge to current IRS priorities and IRS.gov; priorities change).
- Digital asset activities: Mining and trading operations that generate losses alongside personal-use assets have attracted IRC 183 scrutiny in recent examination cycles (hedge to current IRS guidance and IRS.gov).
8.2 IRS Examination Techniques
When the IRS opens an IRC 183 examination, examiners typically issue an Information Document Request (IDR) seeking: all bank records for accounts associated with the activity; written business plans or financial projections; records of time spent; receipts for all claimed expenses; documentation of expert consultations; and records of income generated by the activity. Under IRM 4.10.4 (hedge: verify current IRM version at IRS.gov), examiners are instructed to evaluate all nine factors in Treas. Reg. Section 1.183-2(b) and to consider the overall weight of the evidence. Verify current examination techniques and IRS guidance at IRS.gov and in the current IRM before preparing an IDR response.
9. Responding to an IRC 183 Determination
9.1 The Revenue Agent Report and 30-Day Letter
When an IRS examiner proposes an IRC 183 disallowance, the taxpayer receives a Revenue Agent Report (RAR) and a 30-day letter offering the opportunity to protest to the IRS Office of Appeals. The protest should address each of the nine factors the examiner cited negatively and present the taxpayer's evidence in organized, factor-by-factor form. A protest that ignores adverse factors is less persuasive than one that directly addresses them and provides context. See the IRS Examination Appeals guide in the Related Guides section for Appeals protest mechanics.
9.2 IRS Office of Appeals
Appeals officers reviewing IRC 183 cases apply the same nine-factor framework as examiners. An Appeals conference gives the taxpayer the opportunity to present additional evidence, correct factual errors in the RAR, and negotiate a settlement. Many IRC 183 cases resolve at Appeals -- either by IRS concession, partial concession (deductions allowed in some years but not others), or a negotiated resolution. Appeals officers have settlement authority based on the hazards of litigation; a mixed-factor record with some genuinely strong elements can produce a favorable outcome. Verify current Appeals protest procedures and requirements at IRS.gov.
9.3 Tax Court Petition
If the taxpayer receives a Notice of Deficiency (IRC 6213) following an unsuccessful Appeals protest -- or following examination if the taxpayer bypassed Appeals -- the taxpayer may petition the Tax Court within the deadline specified in IRC 6213 (hedge: verify the current deadline and petition requirements at IRS.gov and the Tax Court's website). The Tax Court reviews IRC 183 determinations de novo on the trial record, applying the nine-factor test to the evidence presented. The standard of proof is preponderance of the evidence (hedge to current Tax Court rules and IRS.gov). Recent T.C. Memorandum decisions continue to develop the nine-factor analysis; verify current case law at IRS.gov and through current legal research before advising on trial strategy.
9.4 Accuracy-Related Penalty Exposure
An IRC 183 disallowance typically triggers an accuracy-related penalty under IRC 6662 (hedge: verify at IRS.gov and in current IRC text). The taxpayer may assert reasonable cause and good faith under IRC 6664(c) as a penalty defense; this requires showing that the taxpayer made a good-faith effort to determine the correct tax and had a reasonable basis for the position. Documentation of profit-motive analysis (reliance on the nine-factor test, contemporaneous records, professional advice) strengthens the reasonable-cause defense. Verify current penalty defense standards at IRS.gov and in the IRC 6662 guide in the Related Guides section.
10. Documentation Best Practices: Building the Profit-Motive Record
The following practices support a profit-motive argument under the nine-factor test. All practices should be verified against current IRS guidance and IRM provisions at IRS.gov; documentation expectations can evolve.
10.1 Business Operations
- Maintain a dedicated bank account and credit card used exclusively for the activity; never commingle personal and activity funds.
- Keep formal books of account using standard accounting practices; update them regularly throughout the year, not at year-end from memory.
- Prepare an annual budget and financial projections; retain each year's budget alongside the year-end actual results and written explanations for variances.
- Maintain a written business plan and update it as the activity evolves; document all strategic changes made in response to losses or changing market conditions.
10.2 Time and Expertise Records
- Keep a contemporaneous log of time spent on the activity; note the date, hours, and nature of the work performed (marketing, production, administration, client meetings, supplier negotiations).
- Retain records of formal training, courses, seminars, trade association memberships, and subscriptions related to the activity.
- Document all consultations with industry experts and retain written summaries of advice received and how the taxpayer responded to that advice.
- Record attempts to change strategy based on expert recommendations; changes in direction are evidence of businesslike responsiveness to new information.
10.3 Responses to Losses
- When the activity produces a loss, document the specific reasons (market conditions, weather, economic environment, unforeseen events) and the taxpayer's corrective actions in writing.
- Retain market research, third-party analyses, or industry data supporting the taxpayer's decision to continue operating despite losses.
- Document any changes in methods, practices, or personnel made in response to losses -- and explain in writing why prior approaches were abandoned.
10.4 Personal-Use Separation
- Where activity assets (horses, aircraft, boats, cameras, vehicles) are also used for personal purposes, maintain a detailed log documenting business vs. personal use allocation by date and purpose.
- Charge fair market fees or rent for any personal use of activity assets; document those charges in writing and at arm's length.
- Do not use activity premises, vehicles, or equipment for personal events without documenting the personal-use allocation and any charge assessed.
11. Special Situations: Crypto, NFTs, Online Content Creators, and Farm Activities
11.1 Cryptocurrency Mining
The IRC 183 profit-motive analysis applies to cryptocurrency mining when the activity generates consistent losses alongside personal-use aspects (for example, hardware used for both mining and personal gaming). The IRS has indicated that cryptocurrency mining may be classified as a business or a hobby depending on the specific facts and circumstances (hedge: verify at IRS.gov and through current IRS guidance; IRS guidance on cryptocurrency mining and IRC 183 continues to evolve). Apply the nine-factor test to the mining activity; factors (1) (businesslike manner), (3) (time and effort), and (8) (financial status) are particularly relevant in typical mining loss scenarios. Verify all current IRS guidance on cryptocurrency mining tax classification at IRS.gov before advising any client.
11.2 NFTs and Digital Collectibles
Self-created NFTs and digital collectibles present novel IRC 183 questions when the creator sells NFTs at a loss or generates minimal income relative to production expenses. The general nine-factor framework applies; no specific safe harbor for NFT creators exists as of July 2026 (hedge: verify at IRS.gov and through current IRS guidance). Factor (9) (personal pleasure) may be particularly relevant where the NFT activity involves an artistic or gaming hobby with obvious recreational elements. Verify all current IRS guidance on digital asset and NFT classification at IRS.gov before advising any client.
11.3 Online Content Creators
Streaming, YouTube, podcasting, and similar online content creation activities that generate consistent losses relative to expenses (equipment, travel, production, software subscriptions) have attracted increasing IRS examination activity in recent years (hedge to current IRS priorities and IRS.gov; priorities change; verify current enforcement posture). Practitioners advising online content creators should focus on factor (1) (businesslike manner): a creator who maintains a production schedule, tracks audience metrics, pursues advertising partnerships and brand deals, and adjusts content strategy based on monetization data presents a stronger profit-motive argument than one who posts irregularly with no attention to income generation. Verify current IRS guidance and examination priorities for online content creators at IRS.gov.
11.4 Farm Activities
Farm activities are subject to the modified 2-of-7 profit presumption under IRC 183(d) for horse activities (Section 4.2, above); the regular three-of-five rule applies to other farm activities. Farm activities with recreational elements -- hunting preserves, vineyards, agritourism operations -- require particularly careful documentation of businesslike operations and should address all nine factors with specificity. Verify all IRC 183 standards applicable to farm activities at IRS.gov and in the current IRM (verify version at IRS.gov).
12. Practitioner Checklist
Use this checklist for any client with recurring activity losses. All items are hedged to current IRC text and IRS.gov; verify before advising any client.
- Apply the nine-factor profit-motive analysis before the return is filed -- not after an examination opens. Evaluate each factor in Treas. Reg. Section 1.183-2(b) against the client's specific facts and document the analysis in the engagement file. If the analysis is close, advise the client to implement corrective documentation practices immediately. Verify the current nine-factor standard at IRS.gov.
- Check whether the IRC 183(d) profit presumption applies for the year at issue. Count the profitable years in the applicable 5-year (or 7-year for horse activities) window ending with the current year. If the presumption applies, note its rebuttable nature in all client communications. Reanalyze the presumption separately for each year under examination. Verify the current presumption rule at IRS.gov.
- Evaluate the IRC 183(e) election and advise the client of the SOL consequences before electing. If the client is in the second tax year of the activity and has not completed the profit-motive period, assess whether the election is strategically appropriate. Advise the client explicitly that the election extends the IRC 6501 assessment SOL for all years in the elected period. Verify current election mechanics at IRS.gov and Rev. Proc. 2004-34 (verify whether superseded).
- Ensure all gross hobby income is reported in full. Even when the activity is classified as a hobby, gross income from it must be reported under IRC 61. Omitting hobby income is a separate compliance issue from the deduction question. Verify current gross income reporting requirements at IRS.gov.
- Identify which IRC 183(b)(1) Tier 1 deductions remain allowable. Determine whether mortgage interest, property taxes, or other Tier 1 amounts attributable to the activity apply and confirm they are correctly reported. Verify the current Tier 1 deduction scope at IRS.gov.
- Advise the client that post-TCJA, hobby expenses are not deductible as miscellaneous itemized deductions. Verify the current status of the miscellaneous itemized deduction suspension at IRS.gov. If it remains suspended, explain clearly that gross hobby income is taxable with virtually no offsetting deduction beyond Tier 1 items. This information is material to the client's decision about whether to contest an IRC 183 determination.
- Establish a contemporaneous documentation system before and during the activity. Provide the client with specific guidance on: separate banking, time logs, expert consultation records, written business plans, and documentation of responses to losses. Confirm implementation at the next annual client meeting and document that confirmation in the engagement file.
- If an IRS examination is opened, address all nine factors in the protest response. Organize the protest by factor; present positive evidence for each and address adverse factors directly rather than ignoring them. A protest that acknowledges weaknesses and provides context is more persuasive than one that only presents favorable facts. Verify current protest requirements at IRS.gov.
- Assess whether to resolve at examination, protest to Appeals, or petition Tax Court. Weigh the strength of each of the nine factors, the dollar amount of the proposed deficiency, the client's risk tolerance, and the post-TCJA tax cost of hobby classification. A factually mixed record with some genuinely strong elements may settle more favorably at Appeals than at examination. Verify current Tax Court petition procedures at IRS.gov and the Tax Court's website.
- Evaluate IRC 6662 accuracy-related penalty exposure separately from the substantive IRC 183 argument. If the IRS proposes a penalty, assess whether the client can establish reasonable cause and good faith under IRC 6664(c). Document any reliance on professional advice, prior IRS guidance, or the contemporaneous profit-motive analysis. Verify current penalty defense standards at IRS.gov.
