It all started back in 1995, when the first online betting site took its very first wager — one of the earliest real-world examples of online payments during a time when most people were still wary of buying anything on the internet. Bettors, however, were eager to test the new frontier, and in doing so, they quietly helped shape what would become one of the fastest-growing digital industries in the world.
From that modest beginning, online betting has evolved into a multibillion-dollar powerhouse. By 2025, the U.S. regulated sports betting market alone is generating over $12 billion in annual revenue and handling hundreds of billions of dollars in wagers each year. What was once a niche pastime has become a central part of how millions of fans engage with their favorite sports.
The industry’s growth has been fueled by constant innovation — from live, in-game betting and mobile-optimized sportsbooks to new wager types that appeal to both casual fans and seasoned bettors. Today, players have an enormous variety of legal betting sites at their fingertips.
And while 1995 marked the beginning, 2018 was the turning point — the year the U.S. Supreme Court struck down the federal ban on sports betting. We’ll explain why that decision changed everything later on.
It’s also worth noting that offshore sportsbooks remain highly popular in 2025, attracting millions of American bettors thanks to their crypto options and fewer restrictions. However, this page will focus exclusively on U.S.-licensed and regulated betting sites — the ones operating legally under state and federal oversight to ensure transparency, security, and player protection.
U.S. regulation on sports betting can still feel confusing in 2025. That’s because the Supreme Court’s landmark 2018 decision removed the federal ban on sports wagering, leaving it up to individual states to decide if and how they want to legalize it. Since then, the country has developed a patchwork of different laws and models.
As of 2025, sports betting is legal in 38 states plus Washington, D.C. Of those, around 30 states allow mobile or online wagering, while others only permit betting in person at casinos, racetracks, or tribal venues. The level of access, tax rates, and market competition vary widely from one state to another.
For instance, Nevada, the long-time sports betting capital, still requires players to register their accounts in person before wagering online — a policy that excludes operators like DraftKings or FanDuel, which lack physical locations there. Florida now has statewide mobile betting through the Seminole Tribe’s Hard Rock Bet app, while North Carolina and Maine joined the legal betting map in 2024. Meanwhile, California and Texas continue to prohibit all forms of sports betting, both online and in person.
Despite these differences, the overall trend is unmistakable: more states are embracing legalization, recognizing its value for consumer protection, job creation, and tax revenue. With each passing year, regulated sports betting becomes a more normalized part of the American sports experience.
At the same time, offshore betting sites remain extremely popular in 2025, serving millions of U.S. players who prefer their broader markets, crypto payments, and fewer restrictions. While you can see some of our favorite offshore betting sites below, this article will focus more on regulated sportsbooks.
The first and most common question is regarding legal sports betting sites and whether winnings from these sites are taxable or not. The answer is yes. Gambling winnings are much like any other earnings. If the earnings go beyond a certain value it’s common for the gambling site, or casino to report the winnings themselves. However, this isn’t always the case and something bettors should check out and be aware of when playing.
It’s imperative that every player is able to deduct gambling losses from their tax declaration. Players that wager with Bitcoin betting sites will face the same taxation laws that players depositing using a more mainstream payment method like PayPal would be under. In order to do this, bettors must deduct gambling losses and provide records that show the amounts of both your winnings and losses; this can be done using casino or online betting receipts, tickets, and statements.
It’s important we emphasize the importance of recording movements of money with regard to gambling. While these rules don’t concern casual bettors, who simply have a flutter on the horses now and again, or place accumulators on the weekend. It does concern the more hardcore players. Gamblers that are invested in the business of gambling, who use it as a primary income, must be aware of declaring these funds or they may get caught out by the taxman.
There are winners and losers in gambling, but even winners can end up on the wrong side if they ignore their tax obligations. In the United States, all gambling winnings are considered taxable income and must be reported to the Internal Revenue Service.
The common belief that gambling winnings are always taxed at a flat 24% rate isn’t entirely accurate. That 24% represents the federal withholding rate, which is applied to certain large payouts, but the actual amount owed depends on the taxpayer’s income bracket. State taxes may also apply in addition to federal liability, depending on where the bettor lives.
Generally, operators must withhold 24% and issue a W-2G form when a player’s winnings exceed specific thresholds, such as:
These forms report both cash and non-cash prizes. If someone wins a car, vacation, or other item, they must pay tax on the item’s fair market value.
Players who use legal sportsbooks—whether online or in person—are subject to the same reporting rules as those gambling in casinos. Bettors can deduct gambling losses on their federal returns, but only up to the total amount of their reported winnings, and only if they itemize deductions. Maintaining accurate records of wagers, deposits, and payouts is essential for compliance.
In short, gambling winnings remain taxable in 2025, and both casual and professional bettors should treat them like any other source of income to avoid penalties later on. Below, we’ll take a look at how this compares to other popular gambling destinations around the world.
Canada takes a very different approach to taxing gambling winnings than the United States. In most cases, Canadians can win large sums—whether from sports betting, casino play, or lotteries—without owing any tax on those winnings.
The key distinction lies in intent and frequency. The Canada Revenue Agency generally considers gambling to be a non-taxable source of windfall income unless it is carried out as a business activity. That means recreational bettors who place occasional wagers, even if they win millions, do not pay tax on those profits.
However, players who gamble professionally—for example, earning a consistent living from betting, poker, or similar activities—may be required to report that income as business earnings. In such cases, their net profits become taxable, but they can also deduct legitimate business expenses.
This distinction applies equally to both online and offline gambling. Contrary to common belief, online poker is not automatically taxed; only players who demonstrate professional-level consistency and organization, such as maintaining bankroll management and using poker as their main source of income, fall under taxable status.
In short, casual bettors in Canada enjoy tax-free gambling winnings, while professional gamblers are treated as self-employed individuals for tax purposes.
In the United Kingdom, bettors continue to enjoy one of the most favorable tax environments in the world. Gambling winnings—whether from sports betting, casino games, poker, or lotteries—are not subject to personal income tax. Players owe no tax on either their stakes or their winnings, regardless of the amount.
This policy has been in place since 2001, when the British government reformed its gambling tax structure. Under then-Chancellor Gordon Brown, the government shifted the burden of taxation from players to operators, introducing a gross profits tax on bookmakers that took effect on January 1, 2002.
Since that change, licensed gambling operators in the UK have paid taxes on their profits, while individual bettors remain exempt. The system is regulated by the UK Gambling Commission, which ensures that operators comply with strict licensing, fairness, and responsible gambling standards.
The absence of taxation on player winnings remains one of the key reasons for the enduring popularity of gambling in the United Kingdom, both online and in retail betting shops.
Australia remains one of the most active gambling markets in the world, with estimates showing that around 80 percent of adults participate in some form of gambling each year. Despite this high level of activity, individual players are not required to pay tax on their gambling winnings.
The Australian Taxation Office classifies gambling as a form of recreation rather than income, meaning that winnings from sports betting, lotteries, or online casinos are treated as tax-free windfalls. The exception applies only to professional gamblers who operate in a structured, business-like way, although such cases are rare.
Similar to the UK, Australia places the tax responsibility on operators. Licensed sportsbooks and online casinos must pay state-level duties and levies based on their profits or turnover, with rates varying between jurisdictions such as New South Wales, Victoria, and Queensland.
While players may face small fees tied to deposits or withdrawals, these charges come from payment processors or exchange rates rather than from government taxation. Overall, gambling remains untaxed at the individual level in Australia, which continues to make it one of the most bettor-friendly systems worldwide.
There are now dozens of licensed and regulated betting sites operating across the United States, giving bettors a wide range of trusted options to choose from. But one question remains: how much does the government take from the winners?
In most countries, the answer is nothing. Players in places like Canada, the United Kingdom, and Australia keep 100 percent of their winnings, whether earned online or in a casino. The United States stands out as an exception, where gambling winnings are treated as taxable income and can be subject to a federal withholding rate of 24 percent, plus any applicable state taxes.
It’s a system that often surprises international bettors and frustrates many Americans, but it reflects the U.S. government’s long-standing approach to treating gambling profits like any other form of income.
