Crypto Gambling Taxes: Complete IRS Guide for 2026

The Basic Rule: All Gambling Winnings Are Taxable

The starting point for understanding crypto gambling taxes is simple: under IRC Section 61, gross income includes all income from whatever source derived. The IRS has consistently held that this includes gambling winnings, and this applies regardless of whether those winnings are received in US dollars, foreign currency, cryptocurrency, or any other form of value.

When you win cryptocurrency through gambling — whether at a poker table, from a sports bet, at an online casino, or through any other wagering activity — you have received taxable income. The taxable amount is the fair market value (FMV) of the cryptocurrency at the time you receive it, measured in US dollars. This is your gambling income for the tax year, reported on your tax return regardless of whether you receive a W-2G, 1099, or any other tax document from the gambling platform.

The fact that many offshore crypto gambling platforms do not issue US tax documents does not eliminate your reporting obligation. The IRS requires taxpayers to report all income, and the absence of third-party reporting makes self-reporting even more critical — if the IRS later identifies unreported gambling income through blockchain analysis or information sharing, the penalties are significantly worse than they would be for an honest reporting error.

2026 Changes: The Big Beautiful Bill Act

The Big Beautiful Bill Act, signed into law in 2025, introduced several significant changes that affect crypto gamblers beginning in the 2026 tax year. Understanding these changes is essential for anyone reporting crypto gambling income.

90% Gambling Loss Deduction Cap

Previously, US tax law allowed gamblers to deduct 100% of their gambling losses against their gambling winnings (but not against other income). Starting in 2026, the deduction is capped at 90% of gambling income. This means that if you have $100,000 in gambling winnings and $100,000 in gambling losses, you can only deduct $90,000 of those losses — leaving $10,000 in net taxable gambling income even though you broke even in reality.

This change has significant implications for high-volume players, particularly poker players and sports bettors who may have large gross win and loss figures even when their net profit is modest. A poker player who wins $500,000 in gross winnings but has $480,000 in buy-ins and losses will now be taxed on $30,000 ($500,000 minus the 90% cap of $450,000) instead of $20,000 under the old rules. For casual players with smaller amounts, the impact is proportionally less significant but still present.

$2,000 Reporting Threshold

The threshold for mandatory withholding and W-2G reporting has been adjusted. For certain types of gambling winnings, the reporting threshold is now $2,000 (previously $600 for some categories). This primarily affects operators rather than players — your obligation to report all winnings remains unchanged regardless of whether a W-2G is issued.

Form 1099-DA (Digital Asset Reporting)

The new Form 1099-DA requires cryptocurrency exchanges and certain digital asset brokers to report transactions to the IRS, similar to how brokerage firms report stock transactions on Form 1099-B. While the specific rules for which gambling-related transactions trigger 1099-DA reporting are still being refined through IRS guidance, the direction is clear: the era of crypto gambling operating in a reporting blind spot is ending.

If you purchase crypto on a US exchange, transfer it to a gambling platform, and later receive winnings back, the exchange will report the outgoing and incoming transfers. While the exchange may not know the transfers are gambling-related, the IRS can infer this through patterns — frequent transfers to known gambling platform addresses, for example. Third-party blockchain analysis firms already provide this capability to tax authorities.

How to Calculate Crypto Gambling Taxes

Crypto gambling taxation involves two distinct layers: gambling income tax and capital gains tax on subsequent cryptocurrency appreciation. Understanding how these layers interact is crucial for accurate reporting.

Layer 1: Gambling Income

When you receive cryptocurrency as gambling winnings, the fair market value at the time of receipt is taxable as ordinary income. Your cost basis in that cryptocurrency is the FMV at the time you received it. For example, if you win 1 ETH when Ethereum is trading at $3,500, you have $3,500 in gambling income and a cost basis of $3,500 in that 1 ETH.

Layer 2: Capital Gains or Losses

If you later sell, trade, or dispose of the cryptocurrency you won, any difference between the sale price and your cost basis (the FMV at the time you received it as winnings) is a capital gain or loss. If you sell that 1 ETH for $4,000, you have a $500 capital gain. If you sell it for $3,000, you have a $500 capital loss. Long-term capital gains rates apply if you held the crypto for more than one year; short-term rates (taxed as ordinary income) apply if you held it for one year or less.

Tax Calculation Examples

The Stablecoin Advantage

The examples above illustrate why many experienced crypto gamblers prefer stablecoins like USDT or USDC for gambling. Because stablecoins maintain a 1:1 peg with the US dollar, there is no capital gains layer — the FMV at receipt is essentially the same as the FMV when you later convert to USD. This dramatically simplifies tax calculations and eliminates the risk that cryptocurrency volatility creates unexpected capital gains or losses between the time you win and the time you sell.

If you gamble with volatile cryptocurrencies like BTC, ETH, or SOL, you need to track the exact FMV at the moment of each win. A $30,000 BTC win that you hold through a price increase to $35,000 creates both $30,000 in gambling income and $5,000 in capital gains — potentially at different tax rates depending on your holding period. With stablecoins, you just track the dollar amount.

The Disposition Question: Is Depositing Crypto a Taxable Event?

One of the most debated questions in crypto gambling taxation is whether transferring cryptocurrency to a gambling platform constitutes a taxable disposition. If you purchased 1 BTC at $40,000 and it is now worth $60,000, and you deposit it at a crypto casino, have you realized a $20,000 capital gain?

The answer is not definitively settled. Some tax professionals argue that depositing crypto at a gambling platform is analogous to exchanging it for chips at a casino — a disposition that triggers capital gains at the time of deposit. Others argue that because you retain the ability to withdraw the crypto (assuming you do not lose it gambling), it is more analogous to a transfer between your own accounts, which is not a taxable event.

The safest approach from a tax compliance perspective is to treat the deposit as a potential disposition and track the cost basis accordingly. If you deposit BTC with a cost basis of $40,000 and an FMV of $60,000, record the potential $20,000 gain. If you later withdraw the same amount, you can argue the disposition did not occur. Consult a tax professional for guidance — this is an area where professional advice is particularly valuable.

Record-Keeping Requirements

Adequate record-keeping is not optional — the IRS requires records sufficient to substantiate all items reported on your return. For crypto gambling, this means maintaining detailed records of every transaction. The following table outlines the minimum information you should track.

Tools for Tracking

Manual record-keeping is feasible for casual players but becomes impractical for anyone with significant volume. Several crypto tax software platforms can help automate the process. Tools like CoinTracker, Koinly, TokenTax, and CoinLedger can import transactions from most exchanges and some gambling platforms. They track cost basis, calculate FMV at the time of each transaction, and generate tax reports compatible with US filing requirements.

For gambling transactions that occur within a platform (not on the blockchain), you may need to manually export or record those transactions, as crypto tax software typically only sees on-chain activity. Many gambling platforms provide transaction history exports that can be imported into tax software or used alongside it.

State Tax Considerations

Federal tax obligations are just part of the picture. Most US states with income taxes also tax gambling winnings, and state treatment can differ from federal rules in important ways.

Seven states have no state income tax: Alaska, Florida, Nevada, South Dakota, Texas, Washington, and Wyoming. Tennessee and New Hampshire do not tax earned income but do tax some investment income (New Hampshire is phasing out its interest and dividends tax). Residents of these states only owe federal tax on crypto gambling winnings.

For residents of states with income tax, the key question is whether the state allows gambling loss deductions. Some states follow federal rules and allow losses up to the level of winnings (now capped at 90% federally). Others, like Massachusetts and Connecticut, do not allow gambling loss deductions at all — meaning your full gross gambling winnings are taxable at the state level even if you had offsetting losses. A few states have unique gambling tax provisions that differ significantly from federal treatment.

International Tax Considerations

For US citizens and residents who gamble at offshore platforms, all winnings are still reportable to the IRS regardless of where the platform is located. US tax obligations follow the citizen, not the geography of the transaction.

Foreign Account Tax Compliance Act (FATCA) reporting may be triggered if you hold cryptocurrency in offshore accounts exceeding certain thresholds. While the application of FATCA to crypto gambling platform balances is not entirely settled, the safest approach is to report foreign financial accounts exceeding $10,000 in aggregate value on FinCEN Form 114 (FBAR) and specified foreign financial assets on Form 8938 if applicable thresholds are met.

For non-US residents gambling at US-based or US-connected platforms, tax treaties between your country and the US may affect withholding and reporting requirements. Many countries tax gambling winnings differently from the US — some exempt gambling winnings entirely, while others tax them at flat rates. Consult a tax professional familiar with international taxation for guidance.

When to Consult a Professional

While this guide provides a foundation for understanding crypto gambling taxes, several situations warrant consulting a qualified CPA or tax attorney who specializes in cryptocurrency taxation.

If your total crypto gambling winnings exceed $10,000 in a tax year, if you have gambling activity on multiple platforms, if you gamble with multiple cryptocurrencies (creating complex FMV tracking requirements), if you are uncertain about whether specific transactions are taxable events, if you have unreported gambling income from prior years, or if you are a professional gambler filing on Schedule C — you should seek professional guidance. The cost of a consultation is typically far less than the potential penalties for incorrect reporting.
