Online gambling has turned into a massive global industry, and while many believe that games of chance are widely accepted in the US, that is not so. California is one of the many states of the United States that do not allow online casinos, as only seven do. New Jersey, Connecticut, West Virginia, Pennsylvania, Delaware, Michigan, and Rhode Island. The Golden State is also unique in not allowing commercial land-based gaming venues, permitting only tribal ones. Yet, card clubs are widely available in this section of the country, and the state lottery runs regular prize draws.
Online Casino Winnings – That said, residents of the City of Angels have options for testing their luck on slots and casino classics such as blackjack and roulette remotely. They are free to do so at offshore sites that accept US gamblers. There are loads of these, and they operate under the watchful eye of a regulator in the jurisdiction where they are based, usually Panama, Curacao, the Isle of Man, or Anjouan. Moreover, many operators that run such hubs online also have social gaming offshoots that function legally in the US as social casinos. These are ones where users buy credits, which they use on games that are identical to the ones featured at real money casinos.
With interactive gaming entertainment available to Los Angeles residents, many wonder if they must pay taxes on winnings attained through enjoying this hobby, given that those funds are generated at sites without servers in the United States. As explained below, the Internal Revenue Service (IRS) and the California Franchise Tax Board (FTB) have clear rules about gambling income, regardless of where they have won.
Federal Tax Laws on Gambling Winnings
Here is something universal across the US. Federally, all gambling winnings are taxable. They must be reported as income, regardless of where they were earned, and it does not matter what casino payment methods were used for depositing or withdrawing. Using cryptos as a transaction option does not affect this. US gamblers must report these on a W-2G form when they have won $600 or more for any form of gambling, attained $1,200 or more from bingo or slots, or collected $5,000 or more from poker tournaments, sweepstakes, or lotteries.
The federal withholding of 24% applies to winnings over $5,000. Of course, not counting the money wagered. All non-residents must report their winnings on Form 1040-NR, and given their non-citizen or permanent resident status, they will get taxed using a flat 30% rate, with no loss deductions. This does not apply to Canadians, who are exempt due to a tax treaty. People who gamble almost full-time can mark themselves as professional gamblers, allowing them to report winnings as self-employment income.
Now, it is essential to note that offshore sites are unlikely to issue Form W-2G. But that does not excuse gamblers from reporting winnings collected at such websites. The rule of thumb here is to jot them under “other income” on Schedule 1 – Form 1040.
California Tax Laws re Online Casino Winnings
Unlike New Hampshire, which offers an exemption for lottery games, California requires that all gambling winnings that residents are lucky or skillful enough to take home get taxed. Like the federal rule, it does not matter where they have won. They could have been attained in-state, out-of-state, online, or offshore; they still are subject to state taxation. Furthermore, California also does not allow deductions for gambling losses, which some regions do. So, even if someone itemizes this on their federal return and deducts their losses, they cannot do the same on their state tax return.
Non-residents are generally not taxed by the state on gambling income they have earned outside California. Yet, the revenue has been generated from a California-based source. In that case, it will be subject to taxation, with winnings reported as Other Income on a California Form 540 (Resident) or Form 540NR (Nonresident/Part-Year Resident).
Everyone is responsible for making estimated tax payments, as California does not automatically withhold taxes. So, anyone who wins at a site licensed in another country must report those profits, which is why it is so pivotal that everyone keeps detailed records of their gaming activity.
Filing Tips & Penalties for Non-Compliance
We suggest that people who gamble regularly keep records for each session separately, including the sums wagered, won, and lost, using a budgeting app. Most online casinos today have a transaction page in account profiles that shows this, making things easier for those who only use one site.
Gamblers must know how to correctly fill out the forms mentioned above and be sure to retain all records for three years. Failure to report gambling winnings can trigger IRS audits, resulting in a 20% negligence penalty and a 75% penalty for fraud or underpaid tax if this is intentional. There are also late filing fines, federal and California ones.
Individuals who win $10,000 or more via offshore betting should consult a tax specialist who can ensure compliance and minimize liabilities and potential future disputes with the IRS or FTB.
