Off-Track Betting Laws and Regulations: Federal Rules, Licensing, Taxes

Off-track betting laws and regulations in the United States sit on a federal foundation — the Interstate Horseracing Act of 1978 — with each state deciding whether to permit the activity and how to license it. Roughly 40 states allow some form of off-track wagering, delivered through brick-and-mortar parlors or online advance deposit wagering (ADW) platforms. The rules cover who can run a facility, who can place a bet, how operators must handle cash and suspicious activity, and how winnings get taxed.

The Federal Law That Makes OTB Legal

The Interstate Horseracing Act (IHA), codified at 15 U.S.C. §§ 3001–3007, is the statute that allows legal wagering on a race in one state from a location in another. Congress passed it in 1978 to stop unauthorized operators from taking bets on races without paying the tracks and horsemen who produce them. The law does not create a right to open an off-track betting business. It sets conditions that must be met before any interstate wager can be accepted.

The Three Required Consents

Before an off-track system can accept a bet on an out-of-state race, three separate approvals are required. The host racing association where the race is run must agree, and it must have a written agreement with the horsemen’s group at that track covering the terms of off-track wagering. The racing commission in the state where the race takes place must consent. And the racing commission in the state where the bettor is placing the wager must also sign off.¹ Accepting interstate wagers without clearing all three creates civil liability to the host state, the host racing association, and the horsemen’s group.²

Why Online Horse Betting Is Allowed

The Unlawful Internet Gambling Enforcement Act (UIGEA), passed in 2006, broadly prohibits businesses from knowingly accepting payments tied to unlawful internet gambling. It carves out an explicit exemption for horse racing: any activity allowed under the IHA is excluded from the definition of “unlawful Internet gambling.”³ That exemption is why ADW apps can lawfully take online deposits and accept wagers. Payment processors still flag gambling-related transactions with merchant category codes, and individual banks may decline them even when the underlying activity is legal.

What HISA Does Not Cover

The Horseracing Integrity and Safety Act (HISA) is sometimes assumed to regulate betting. It does not. HISA governs anti-doping, medication control, and racetrack safety for Thoroughbred racing. The statute uses the existence of interstate and advance deposit wagering only to define which races fall under the Authority’s jurisdiction; the Authority has no power over wagering operations themselves.⁴ OTB operators answer to state racing commissions and the IHA framework.

State Licensing

Federal law sets the floor. Each state decides whether to allow off-track betting at all and how tightly to regulate it. Most states route this through a racing commission or gaming control board that writes administrative rules, approves or denies licenses, and can revoke them for violations.

Licensing is not quick. Applicants face background checks that examine criminal history, prior involvement in regulated gambling, and financial integrity. Owners and key stakeholders typically submit fingerprints and years of personal and financial records. Financial-stability requirements are equally demanding: applicants must demonstrate enough capital to cover payouts and operating costs, and most states require surety bonds.

For physical locations, many states also weigh community impact. Public hearings let residents and local businesses weigh in, and a commission can deny a license if the proposed parlor does not serve the public interest.

The Multi-State Compact

For people who work or operate across state lines, the National Racing Compact reduces duplicate paperwork. This interstate governmental entity, authorized by member states and approved by the FBI to receive criminal history data, lets an applicant complete a single license application with one set of fingerprints. The national license is recognized by all member states, and the licensee pays only a participation fee in each additional state. The compact does not replace state authority, but it avoids repeating a full background check in every jurisdiction.

Rules for Online and Advance Deposit Wagering

Advance deposit wagering is how most casual bettors interact with horse racing today. The defining feature is the pre-funded account: you deposit money before placing any wager, which prevents betting on credit and caps exposure to funds on hand.

ADW platforms must verify that every user meets the minimum age, which is 18 in some states and 21 in others. These systems cross-reference applicant data against government databases and credit bureau records at account creation. A failure to maintain effective age gates can lead to license suspension.

Geo-fencing is equally non-negotiable. Every ADW app uses GPS and IP tracking to confirm the bettor is physically located in a state where wagering is legal. A bet attempted from a prohibited jurisdiction gets blocked automatically. That technology is what keeps a platform licensed in one state from accidentally accepting wagers from a state that has not authorized the activity.

Digital operators also face data-security standards that are often stricter than those for physical parlors, with encryption requirements and regulatory audits. Responsible-gambling tools must be built directly into the platform: deposit limits, cooling-off periods, and self-exclusion options that lock a user out for a chosen timeframe. State regulators look at whether these tools actually work.

Zoning for Physical Parlors

State racing commission approval does not clear every hurdle. Opening a physical OTB parlor also requires passing local zoning. Most jurisdictions impose buffer zones that prohibit betting facilities near schools, places of worship, and playgrounds. Minimum distances of 500 to 1,000 feet are common.

Local municipalities often hold the decisive card through special use permits. A city council can block a location that conflicts with local land-use policy even after state sign-off. Zoning rules may also regulate internal layout and exterior appearance, requiring that the betting area not be visible from the street or that signage stay within set dimensions. Violations can lead to permit revocation and a full shutdown, and community groups have successfully litigated against operators who failed to keep required distances from protected zones.

Anti-Money Laundering Obligations

OTB operations that meet certain revenue thresholds fall under the Bank Secrecy Act and carry the same AML obligations as casinos. FinCEN treats OTB establishments that permit account wagering and have gross annual gaming revenue above $1 million as “casinos” for BSA purposes.⁵

Two reporting duties matter most. A Currency Transaction Report must be filed whenever a customer conducts cash transactions exceeding $10,000 in a single gaming day, and multiple smaller transactions by the same customer that day are aggregated toward the threshold.⁵ A Suspicious Activity Report must be filed for any transaction or pattern involving $5,000 or more in funds that appears designed to evade reporting, lacks a lawful business purpose, or involves proceeds from illegal activity. SARs are due within 30 days of detection, with a maximum extension to 60 days if no suspect has been identified.⁶ Supporting documentation must be kept for five years.

Insider Wagering Restrictions

People inside the racing industry face strict limits on betting. Most state racing commissions follow rules modeled on the Association of Racing Commissioners International (ARCI) Model Rules, which draw lines by role:

Trainers may bet only on their own horse in a race where they have an entry. Betting against your own horse, or on another trainer’s entry in that race, is prohibited.
Jockeys may wager only on their own mount, and only to win or in combination bets where the mount finishes first.
Racing officials and their assistants cannot bet on any race under their jurisdiction at all.

Violations carry administrative penalties that include fines up to $10,000, license suspensions of up to five years, license revocation, and forfeiture of purse money. All licensees must also report wagering irregularities they become aware of to the commission. Criminal penalties for insider betting, where they exist, come from state law rather than the model rules.

Taxes on Winnings

Tax rules in off-track betting run in two directions. The operator has reporting and withholding duties, and the bettor has an independent duty to report all gambling income. These are separate obligations.

What the Operator Reports

Starting in 2026, operators must issue IRS Form W-2G when a bettor’s winnings reach $2,000 and the payout is at least 300 times the amount wagered. The threshold increased from $600 due to inflation adjustments that now apply to the W-2G reporting minimum annually.⁷ Both conditions must be met. A $2,500 payout on a $50 bet would not trigger a W-2G, because the odds ratio is only 50:1 even though the dollar amount clears $2,000.

When winnings minus the wager exceed $5,000 and the payout is at least 300 times the bet, the operator must withhold 24% of the proceeds for federal income taxes. The $5,000 withholding threshold was not adjusted for inflation and remains unchanged for 2026.⁷ States with income taxes may require additional withholding on top.

What You Owe as a Bettor

You owe taxes on all gambling winnings, not just the ones large enough to trigger a W-2G. The IRS requires every dollar of gambling income to be reported on Schedule 1 of Form 1040, including wins that fall below the reporting threshold.⁸

Gambling losses are deductible, but only if you itemize on Schedule A, and only up to the amount of gambling income you report. Losses cannot create a net deduction that offsets other income.⁹ Keep records of wins and losses throughout the year. Without documentation, the IRS will count the winnings and disallow the losses.

Deadlines to Cash Winning Tickets

Winning pari-mutuel tickets do not stay valid forever. Every state sets a deadline for cashing them, and the window runs from as few as 60 days to the end of the following calendar year, depending on the jurisdiction. After the deadline, unclaimed funds are treated as abandoned property and escheat to the state. In most cases the money goes into the state’s general fund or education accounts rather than back to the track or the betting pool. If you have old tickets, check your state racing commission for the applicable deadline before it runs out.
