Tax Implications of Online Sports Betting

The Intersection of Fantasy Sports and Federal Tax Law

As the excitement of each new fantasy sports season approaches, many enthusiasts are setting their rosters and entering daily or weekly contests. However, it is vital to understand that the federal tax law on online sports betting is a complex, evolving landscape. While the tax code does not have a section specifically titled “Fantasy Football,” the IRS has remained steadfast in its position: fantasy sports and gaming competitions involving entry fees and cash prizes constitute gambling activities for tax purposes. This stance was recently reinforced in a private letter ruling, signaling that the agency is paying closer attention to the digital arena.

Whether you are participating in high-stakes fantasy forums or niche competitions for golf, bowling, or birdwatching, the fiscal reality is the same. Gambling winnings are taxable income regardless of the venue. From the local church bingo hall to a sophisticated online sportsbook, the IRS expects its share. It is also worth noting that state income tax laws vary significantly; while some states mirror federal guidelines, others may have specific thresholds or restrictions on how you report your fantasy sports profits.

How to Calculate and Report Your Winnings

When it comes time to file, don’t assume that a lack of paperwork means you are off the hook. Beginning in calendar year 2026, online gaming platforms and online sportsbooks have a legal obligation to report annual net winnings of $2,000 or more to the IRS using either Form W2-G or 1099-MISC. Furthermore, if you receive your payouts through third-party payment processors like PayPal or Venmo, you will likely receive a Form 1099-K. Because the IRS receives copies of these documents, failing to include them on your return is a quick way to trigger an audit or a deficiency notice.

Even if your winnings fall below the $2,000 threshold and you do not receive a form, you are still legally required to report that income. Generally, the gaming organizer calculates your net profit by taking your total winnings, subtracting the entry fee, and adding any bonuses received. This net figure is then reported as “Other Income” on your individual tax return. Staying proactive by tracking gambling winnings and losses throughout the season is the best way to ensure accuracy and avoid a headache during the spring filing season.

Navigating the Rules for Deducting Losses

For the vast majority of players, the IRS classifies them as amateur gamblers. This classification carries specific limitations on how you can offset your wins. An amateur’s wagering losses can only be claimed as a miscellaneous itemized deduction. This means if you take the standard deduction, you cannot deduct any of your losses, and you must pay taxes on the full amount of your winnings. For those who do itemize, your deduction is strictly limited to the amount of winnings you reported. You cannot use a “bad year” in fantasy football to reduce your taxable salary or other types of income.

The passing of the One Big Beautiful Bill act has changed the amount of gambling losses taxpayers are able to deduct. Starting in calendar year 2026, the gambling loss deduction that is used to offset gambling winnings is limited to 90% of gambling losses. For example, if you won $10,000 but had losses of $10,000, you will only be able to deduct $9,000 of gambling losses, which creates taxable income from gambling of $1,000.

The rules do allow some flexibility in the types of gambling you combine. For instance, you could use losses from a losing streak at a blackjack table to offset winnings from a fantasy baseball league. However, you cannot carry excess losses forward to future years. These unused gambling losses are simply gone. Additionally, remember that out-of-pocket expenses—such as the cost of a trip to a sports bar, meals, or travel to a live draft—are considered nondeductible personal expenses and cannot be included in your loss calculations.

Amateur vs. Professional Status

There is a significant difference in how the government views those who play for fun versus those who play for a living. If you can prove that you are in the business of gambling, you may qualify as a professional gambler. This status allows you to deduct the full amount of your losses as business expenses and potentially deduct other costs like home office expenses or data subscriptions. However, the IRS sets a very high bar for this classification, utilizing a nine-factor test to determine if you have a legitimate profit motive.

• The manner in which you carry on the activity (business-like records).
• Your expertise in the activity.
• The time and effort expended.
• The expectation that assets used may appreciate in value.
• Your success in other similar or dissimilar activities.
• Your history of income and losses in the activity.
• Your amount of occasional profits, if any, that are earned.
• Your financial status and whether you rely on this income for your livelihood.
• The element of personal pleasure or recreation involved.

Strategic Record Keeping for Sports Bettors

The most effective way to manage your tax liability is to maintain a contemporaneous log of your activity. Relying on an app’s year-end summary can be risky, especially if you use multiple platforms. By keeping a detailed diary of your bets, entry fees, and payouts, you can confidently claim gambling loss deductions to the full extent permitted by law. Understanding the federal tax law on online sports betting now will prevent surprises when the season ends. If you find yourself winning consistently, it may be time to contact your tax advisor to discuss how these winnings affect your overall tax bracket and whether you should be making estimated tax payments throughout the year.
