Updated for the One Big Beautiful Bill Act (P.L. 119-21, signed July 4, 2025) - The OBBBA permanently extended TCJA's expanded definition of 'losses from wagering transactions' to include all business expenses, and added the 90% loss cap. Professional gambler status is now LESS advantageous than before 2026. Last reviewed: July 2026 by Greg Monaco, CPA

Professional gambler status lets you report gambling activity on Schedule C - deducting business expenses, building Social Security credits, and contributing to retirement plans. But the OBBBA's 90% loss cap has fundamentally changed the math. In many cases, professional status now creates a worse tax outcome than recreational status. This guide covers the legal standard, the documentation, and the 2026 reality.
Before you get to Schedule C, identify the taxpayer and the entity. Schedule C is the route for an individual sole proprietor or a disregarded single-member LLC whose facts establish a Section 162 gambling trade or business. It is NOT the owner's route when the gambling is carried on by a partnership or S corporation: there, the entity files its own return, separately states the wagering gains and losses (Schedule K-1, including the Code K information the instructions require), and the individual partner or shareholder reports those items through Schedule E, not a second Schedule C - while a non-business entity routes the owner back to the casual-gambling lines. Forming an LLC or making an S election does not by itself create professional status; the Groetzinger facts still have to be there. And basis, at-risk, passive-activity, excess-business-loss, reasonable-compensation (S corporation), and Section 165(d) limits do not disappear because an entity exists.
The Groetzinger Standard: How the IRS Defines a Professional Gambler
The Supreme Court established the standard in Commissioner v. Groetzinger (480 U.S. 23, 1987). Robert Groetzinger went to the racetrack 6 days per week for 48 weeks per year, spending 60-80 hours per week studying racing data and placing wagers. He wagered $72,032, won $70,000, and had a net loss of $2,032. He had no other employment.
The Court ruled 6-3 (Justice Blackmun writing) that gambling constitutes a 'trade or business' when the taxpayer pursues it full time, in good faith, and with regularity, to the production of income for a livelihood. The Court explicitly rejected the 'Frankfurter gloss' - you do NOT need to hold yourself out to others or sell goods/services.
The Nine-Factor Hobby Loss Test (IRC Section 183)
The IRS applies these nine factors from Treas. Reg. 1.183-2(b) to determine if your gambling is a business or hobby:
Factor 1: Manner Carried On
The single most critical factor. Do you keep detailed records, maintain a separate bank account, track results in accounting software, and operate with a written business plan? A contemporaneous gambling diary per Rev. Proc. 77-29 is essential.
Factor 2: Expertise
Have you studied the games, developed and refined systems, attended training, kept records, and adapted your method over time? Treas. Reg. 1.183-2 weighs preparation, expertise, and operating method on all the facts - it does not rank poker over slots as a matter of law, so a systematic, well-documented slot player can satisfy this factor while a casual poker player may not. Baxter v. United States (arising under the former Sections 1348 and 911 maximum-tax rules, on extraordinary facts) treated a full-time professional poker player's winnings as earned personal-service income; it is not a modern Section 183 skill-game taxonomy or a general rule that poker skill by itself establishes a gambling trade or business.
Factor 3: Time and Effort
Groetzinger spent 60-80 hours/week. Myers prevailed at roughly 40 hours/week while also driving a truck. There's no minimum-hours rule - courts weigh continuity, regularity, and profit motive, and fewer hours simply means the other facts have to carry more weight.
Factor 4: Expectation of Asset Appreciation
Universally neutral/inapplicable to gambling. No assets appreciate.
Factor 5: Success in Similar Activities
Limited value unless you've run other gambling-related businesses.
Factor 6: History of Income/Losses
Persistent unexplained losses indicate hobby. The IRC 183(d) presumption (profit in 3 of 5 years) is rarely met by gamblers, but failing it doesn't automatically make you a hobbyist.
Factor 7: Occasional Profits
Must be proportionate to cumulative losses and investment of time.
Factor 8: Financial Status
A high-income professional claiming gambling losses raises hobby red flags. Merkin: Park Avenue psychiatrist - overstated hours (claimed 1,128, actual 319).
Factor 9: Personal Pleasure
The most challenging factor. Gambling is inherently recreational, but personal enjoyment doesn't automatically disqualify business status.
What the case law actually shows: commentators have tabulated the decided cases and found taxpayers with more favorable facts win more often - no surprise. But Treas. Reg. §1.183-2(b) says the determination is NOT made by counting factors, so treat any '3 factors = 60%' style scoring as a reading aid, not a probability. The IRS and the courts look at the whole picture.
Professional vs. Recreational: Side-by-Side Comparison
| Feature | Recreational Gambler | Professional Gambler |
|---|---|---|
| Income reported on | Schedule 1, Line 8b | Schedule C |
| Losses reported on | Schedule A, Line 16 (must itemize) | Schedule C (no itemizing needed) |
| Business expenses | NOT deductible (OBBBA made permanent) | Part of 90% cap calculation |
| SE tax | None | 15.3% on net profit |
| 90% loss cap | Applies to Schedule A losses | Applies to ALL losses + expenses combined |
| Net Operating Loss | Not available | Not available (165(d) prohibits) |
| QBI deduction | Not applicable | Conditional - gambling gains/losses may be QBI only if a valid Section 162 gambling trade or business exists and each item meets Section 199A rules (Form 1120-S/1065/8995 instructions make this an entity/taxpayer-level determination); not an automatic 20%, and wage/UBIA and taxable-income limits still apply |
| Retirement plans | Not applicable | Solo 401(k), SEP-IRA available |
| Health insurance | Not deductible as business | Deductible under IRC 162(l) |
| Social Security credits | Not earned | Earned through SE tax |
Why Professional Status Is Now LESS Advantageous (OBBBA 2026)
Before the OBBBA, professional gamblers had a clear advantage: the Mayo v. Commissioner (136 T.C. No. 4, 2011) decision allowed business expenses (travel, software, coaching, home office) to be deducted separately from the IRC 165(d) cap on wagering losses. The TCJA (2018-2025) reversed Mayo, but it was set to expire.
The OBBBA made Mayo's reversal permanent. Starting TY2026, ALL deductions from wagering transactions - including business expenses - fall under the 90% cap. This creates a 'double hit' for professional gamblers:
Worked Example: Professional Gambler in 2026
- Gross winnings: $700,000
- Wagering losses: $560,000
- Business expenses (travel, software, coaching, home office): $70,000
- Total deductions: $630,000
- 90% of total deductions: $567,000
- Taxable income: $133,000 - despite only ~$70,000 of actual economic profit ($700K - $560K - $70K), so ~$63,000 is phantom income created purely by the 90% cap
- Federal before any conditional QBI deduction: SE base $133,000 × 92.35% = $122,825.50; SE tax = $18,792.30; deductible half = $9,396.15; taxable income after the $16,100 single standard deduction = $107,503.85; graduated federal income tax = $18,398.92; combined federal tax ≈ $37,191
- NJ is not $0. On simplified single/no-other-income facts, the result depends on how the separate $70,000 of business expenses is classified under NJ law: roughly $2,321 to $6,728, not zero. A return-specific NJ category analysis is required.
A recreational gambler with the same $700K wins and $560K losses (but no deductible business expenses) faces this math under OBBBA §70114: 90% of $560K losses = $504K deductible, so taxable income = $700K - $504K = $196,000. That's $140,000 of actual economic profit plus $56,000 of disallowed-loss 'phantom income'. Using the 2026 single brackets, federal tax on $196,000 is $39,638: $17,966 through $105,700 plus $90,300 × 24% ($21,672). Tax on $140,000 is $26,198, so the $56,000 phantom increment adds $13,440. Professional status changes the deduction and SE-tax mechanics; it is not a flat marginal-rate comparison.
When Professional Status Still Makes Sense
Professional status can still be beneficial when you're consistently profitable:
- Net profit above $50K consistently: SE tax hurts, but the QBI deduction (up to 20%, if a valid Section 162 gambling trade or business exists and the other Section 199A tests are met), health insurance deduction, and retirement plan contributions may offset it
- Solo 401(k) contributions: Up to $24,500 employee deferral (TY2026) + employer profit-sharing of ~20% of net self-employment earnings (the 25% plan rate translates to ~20% of net profit for a sole proprietor) = significant tax-deferred savings. Example: $100K net profit allows ~$43,100 in total contributions
- Health insurance: Self-employed health insurance deduction under IRC 162(l) - available to professional gamblers but NOT recreational
- Social Security credits: Earned through SE tax. Minimum ~$6,920 in net SE income for 4 credits per year; 40 credits (10 years) = retirement eligibility
Key Cases That Shaped the Law
Winners (Taxpayers Who Qualified)
- Groetzinger (1987): Supreme Court, 6-3. Full-time racetrack bettor, 60-80 hrs/week
- Castagnetta (T.C. Summ. Op. 2006-24): Part-time truck driver, 40+ hrs/week horse racing, detailed records. (Summary opinion - nonprecedential under IRC Section 7463(b); persuasive illustration only.)
- Myers: Trucker, ~40 hrs/week slots over 10 years. (Decided as a Tax Court summary opinion - nonprecedential under IRC Section 7463(b); verify the exact citation before relying on it.)
Loss-Deduction / Former-Law Cases (not professional-status holdings)
- Kochevar (T.C. Memo. 1995-607): The court assumed business status and decided a Section 165(d) wagering-loss issue for the government; it did NOT hold the taxpayer was a professional gambler. It illustrates that progressive slot play is not automatically disqualifying, not a favorable status outcome.
Losers (Taxpayers Who Failed)
- Boneparte (T.C. Memo. 2017-193): 8 of 9 factors against; 20% accuracy penalty imposed
- Merkin (T.C. Memo. 2008-146): Park Avenue psychiatrist; overstated hours (1,128 claimed vs. 319 actual)
- Mercier (T.C. Memo. 2023-59): No separate bank account, no contemporaneous records; switched from Schedule A to Schedule C after receiving deficiency notice - red flag
- Zalesiak (T.C. Summ. Op. 2019-16): 98.1% of income from day job. (Summary opinion - nonprecedential under IRC Section 7463(b).)
Documentation Requirements
Professional gambler status lives or dies on documentation. You need:
- Contemporaneous gambling log per Rev. Proc. 77-29: date, type of gambling, location/platform, start/end time, buy-in amount, cash-out amount, net result, companions present
- Separate bank account for all gambling activity
- Business plan documenting your approach, time commitment, and profit targets
- Receipts for all business expenses (travel, equipment, software subscriptions)
- Platform win/loss statements from every sportsbook and casino
- W-2G forms with reconciliation to session results
- Time log documenting hours spent - be honest (Merkin lost for overstating hours)
NJ Treatment of Professional Gamblers
How NJ taxes a federally-qualifying professional gambler is not clearly settled. N.J.S.A. 54A:5-1(g) puts gambling winnings in NJ's net-gambling category (Category (g), Line 24, same-year netting). But N.J.A.C. 18:35-1.1 generally includes income from an activity that qualifies and reports as a federal trade or business in NJ's net-profits-from-business category (Category (b)) - reduced by allowed business expenses. Which category a professional's results belong in (and where the expenses go - NJ does not allow netting across categories) is a position decision on your specific facts; as of July 2026, NJ has published no guidance squarely on point. Do not assume revenue in one category and expenses in another, and do not assume the recreational and professional NJ answers are identical.
Worked Example: Professional vs. Recreational Gambler Comparison
Meet Anthony, a NJ resident who plays poker full-time. He has no W-2 employment. He plays 50+ hours per week at Borgata, online (WSOP.com/PokerStars NJ), and travels to tournaments.
Anthony's 2025 Gambling Activity
| Item | Amount |
|---|---|
| Gross poker winnings (cash games + tournaments) | $185,000 |
| Gross poker losses | $142,000 |
| Business expenses: travel (flights, hotels, meals) | $18,000 |
| Business expenses: coaching, software, database subs | $4,200 |
| Business expenses: home office | $3,600 |
| Net economic profit | $17,200 |
Scenario A: Professional Gambler (Schedule C) - TY2025
| Line | Amount |
|---|---|
| Schedule C gross income | $185,000 |
| Wagering losses + expenses ($142,000 + $25,800) | ($167,800) |
| Schedule C net profit | $17,200 |
| SE tax (15.3% x 92.35% of $17,200) | $2,432 |
| QBI deduction (20% of $15,984 = net profit minus the $1,216 deductible half of SE tax per Reg. 1.199A-3(b)(1)(vi); available only if a valid Section 162 gambling trade or business exists and the Section 199A tests are met) | ($3,197) |
| Federal income tax (after standard deduction) | ~$0 |
| Total federal tax | ~$2,432 |
Note: the QBI line is shown only if Section 199A applies to this gambling trade or business - a conditional, item-by-item determination, not an automatic 20% - and it does not change this result. The standard deduction already reduces taxable income to about $0, so federal income tax is ~$0 with or without QBI.
Scenario B: Recreational Gambler (Schedule A) - TY2025
| Line | Amount |
|---|---|
| Gambling income (Schedule 1, Line 8b) | $185,000 |
| Gambling losses (Schedule A, Line 16) - itemizing; standard deduction forgone (they are mutually exclusive) | ($142,000) |
| Business expenses | NOT deductible |
| Federal taxable income | $43,000 |
| Federal income tax (2025 single brackets) | ~$4,922 |
| SE tax | $0 |
| Total federal tax | ~$4,922 |
(this example assumes you itemize - if you take the standard deduction, losses provide no federal offset)
NJ Return (Both Scenarios)
| Line | Amount |
|---|---|
| Net gambling income (Line 24): $185,000 - $142,000 | $43,000 |
| NJ exemptions | ($1,000) |
| NJ taxable income | $42,000 |
| NJ GIT | ~$828 |
In TY2025, professional status saves Anthony ~$2,500 ($4,922 - $2,432): Schedule C absorbs both the wagering losses and the business expenses, while the recreational filer must give up the standard deduction to itemize the losses (see the corrected Scenario B above). On the NJ side, the recreational scenario is straightforward Category (g) netting ($43,000 on Line 24); the professional scenario's NJ category is a position decision (see 'NJ Treatment' above) - the $828 figure assumes Category (g) treatment and could differ materially under a Category (b) business classification.
2026 Comparison: The 90% Cap Destroys Professional Status
Under the OBBBA's 90% cap (Section 70114), Anthony's total deductions of $167,800 are capped at $151,020 (90% x $167,800 in combined losses and expenses). His Schedule C taxable income becomes $185,000 - $151,020 = $33,980. SE tax: ~$4,800. Federal income tax after the standard deduction: ~$1,600. Total federal tax: ~$6,400 - on $17,200 of actual profit. As a recreational gambler under the 90% cap: losses are capped at $127,800 (90% x $142,000), and because those losses are an itemized deduction he must forgo the standard deduction - taxable income is $185,000 - $127,800 = $57,200, and the federal tax on it (2026 single brackets) is ~$7,296. No SE tax. Professional status still saves Anthony ~$900 in 2026 on these facts - the 90% cap narrows the gap but does not flip it. (Every line here assumes no other deductions; QBI is left out here because it is conditional on a valid Section 162 gambling trade or business and does not change this result; the NJ classification is a separate open question - see NJ Treatment above.) NJ still allows 100% netting: $43,000 on Line 24 regardless. (This example sits below the Section 68 '2/37' threshold of $640,600 single / $768,700 MFJ; a higher-income itemizer would lose a further ~2/37 of the surviving loss deduction to the revived Section 68 limitation, on top of the 90% cap.)
Frequently Asked Questions
Can I be a professional gambler if I have a day job?
Yes. Myers succeeded while working as a trucker. The key is whether you pursue gambling 'with regularity to the production of income' - not whether it's your sole occupation. However, if 98%+ of your income comes from your day job (Zalesiak), it's very hard to qualify.
Does playing slots disqualify me from professional status?
No. Kochevar held that progressive slots are not automatically disqualifying. However, purely chance-based games make Factor 2 (expertise) harder to satisfy.
Is professional gambler income subject to self-employment tax?
Yes. Net Schedule C profit is subject to 15.3% SE tax (12.4% Social Security on the first $184,500 for TY2026 + 2.9% Medicare on all earnings). The 0.9% Additional Medicare Tax applies above $200,000 (single) / $250,000 (MFJ).
Should I switch from recreational to professional status?
Run the numbers first. With the 90% loss cap, professional status increases your tax bill in many scenarios - especially if you're break-even or have significant non-wagering business expenses. Use the contact form to model both scenarios with your actual numbers.
Does forming an LLC or S corporation make me a professional gambler?
No. Entity choice and professional status are separate questions - the Groetzinger facts-and-circumstances test decides status, and an entity does not supply those facts. The return path also differs by entity: an individual or single-member (disregarded) LLC uses Schedule C, but a gambling partnership or S corporation files its own return, separately states the wagering gains and losses on Schedule K-1, and routes them to the owner through Schedule E - not a second Schedule C. A non-business entity instead routes the owner to the casual-gambling lines. Basis, at-risk, passive-activity, reasonable-compensation (S corporation), excess-business-loss, and the Section 165(d) loss limit all still apply.
