Keeping gambling records

Why keeping gambling records matters for US players

Keeping gambling records sounds like homework, but it answers three practical questions: what do I owe in tax, what can I prove if a casino holds my money, and what is gambling really costing me? Most players can't answer any of them from memory, because wins stick in the mind and losses blur together.

The tax side comes first. The IRS treats gambling winnings as taxable income, and the W-2G form only covers certain larger wins. Everything else is still reportable, and losses can only be claimed against winnings if you can support them. Our gambling taxes guide covers the full picture.

The second reason is specific to offshore play. The casinos US players see most, including our partners, are licensed (if at all) outside the US and not regulated by any US state. There is no state gaming board to file a complaint with, so a dispute comes down to your evidence against the casino's server logs.

The third reason is personal. A running total of net results is the clearest reality check there is, and it fits naturally with a gambling budget.

What gambling records to keep: the full checklist

You don't need special software. You need the same handful of facts for every session and every money movement, saved in one place.

How to start a gambling log in six steps

A spreadsheet or a notes app works fine. What matters is that you fill it in at the end of every session, not at the end of the year.

1. Create one sheet with columns for date, casino, game type, starting balance, ending balance, net result and notes.
2. Add a second sheet for money movements: deposits and withdrawals, each with method, amount, fee and reference number.
3. Before your first session at any casino, save a copy of its banking page, bonus terms and general terms (a PDF print or screenshots with the date visible).
4. At the end of each session, write the ending balance before you close the browser, then work out the net result.
5. Once a week, match the money sheet against your bank, card or crypto wallet history and fix any gaps.
6. Once a month, total your wins and losses separately and compare them with the budget you set.

Notice that wins and losses are totaled separately as well as netted. That split is what matters for tax purposes, because winnings are reported as income and losses are a separate deduction.

Gambling records and taxes: W-2G, winnings and losses

Under the IRS instructions for Form W-2G (opens in a new tab), a payer files a W-2G for slot, bingo or keno winnings of $2,000 or more for payments made in 2026 (keno is measured net of the wager). For other wagering, such as sports bets, the win must meet the threshold and be at least 300 times the stake.

Slots, bingo and keno have no regular withholding. Regular gambling withholding of 24% applies to certain other winnings where the win minus the wager exceeds $5,000, and 24% backup withholding can apply if you don't give the payer a correct taxpayer ID number.

The threshold is a reporting rule, not a tax-free allowance. A $600 slot win with no form is still income. That is why your own log matters more than any form a casino sends.

The loss deduction and the 90% cap

Wagering losses are deductible only to the extent of wagering gains for the same year. From the 2026 tax year, the 2025 federal tax law is reported to limit the deduction to 90% of wagering losses, still capped at your gains. An IRS proposed rule in the Federal Register (April 17, 2026) (opens in a new tab) describes the same limit. Check current IRS guidance or a tax professional before you file, and read our gambling loss deduction page for the detail.

Whether you need to itemize to claim losses isn't confirmed on an IRS page we can cite here, so ask a tax preparer. This page explains records, not tax advice for your situation.

Keeping casino records when there is no state regulator

At a state-licensed casino in New Jersey, Pennsylvania or Michigan, a player can complain to the state regulator. At an offshore casino there is no such route, which is explained in our page on player protections offshore vs licensed. Your records become the case file.

Timing matters. SlotoCash's terms (opens in a new tab) say disputes must be submitted within 14 days and that server records are final. Silver Oak's terms (opens in a new tab) are tighter: disputes within 3 days of the wager, with replies within 28 days through a Central Dispute System run by the software provider. Miss those windows and the casino can refuse to look at the complaint.

Inactivity is the other trap. SlotoCash's terms say balances are voided after 12 months without a login, Miami Club's terms remove real-money balances after 12 months (reinstatable on request), and Silver Oak marks accounts inactive after two years. A dated log reminds you that money is sitting there.

If something goes wrong, follow our casino complaint guide and attach your log, terms snapshots and chat transcripts.

Recording withdrawals, caps, fees and KYC documents

Withdrawal records catch the most expensive problems: fees you didn't expect, caps that split a win into weekly payments, and requests that sit in pending for weeks. Published figures also conflict, which makes a dated copy of the page you relied on valuable.

Log each withdrawal request the day you make it, with the method, amount and any fee quoted. If the payment arrives short, the record shows exactly where the gap is. Our pages on withdrawal limits and pending withdrawals explain both issues.

Keep a list of the documents you sent for verification and the date. Partners' terms ask for photo ID, proof of address and, in some cases, card photos or a selfie with ID, and repeated document requests are a common complaint in third-party reviews. See KYC documents for what casinos usually ask for.

Keeping gambling records for crypto deposits and payouts

Crypto adds a layer, because the coin's dollar value moves between the day you deposit and the day you withdraw. Record the dollar amount the casino credits, the coin amount, the wallet address and the transaction ID for every transfer.

Crypto payments generally can't be reversed, as the FTC warns, so a typo in an address is permanent. A clean log is also the only way to rebuild your history if an exchange account closes. Our Bitcoin banking guide covers deposits and withdrawals in more depth.

• Note the casino's dollar credit, not just the coin amount.
• Save the transaction ID (hash) for each deposit and payout.
• Write down any network or casino fee separately.
• Export your exchange and wallet history at least every quarter.

Keeping records of bonus terms and wagering progress

Bonus disputes are among the most common complaints about offshore casinos: winnings voided for breaking a max bet rule or for playing an excluded game. Writing down the rules when you claim, and checking progress as you play, protects you.

Take SlotoCash's welcome terms as published: 25x wagering on deposit plus bonus, a $10 maximum bet per spin while the bonus is active, and slots, keno and scratch cards only. A $100 deposit with a 200% match gives $300 in play, so the wagering is 25 × $300 = $7,500. Log the code, the date, the $7,500 target and the $10 limit, then note your wagered total after each session.

Our guides to wagering requirements and bonus terms red flags show what else to watch. Remember that table games are often excluded or weighted lower.

Using gambling records to keep play affordable

The house edge means losses are likely over time, and a log makes that visible in dollars. If your monthly net figure is bigger than you planned, that is useful information, not a reason to play more to win it back.

Set a monthly limit, compare it with your log, and use casino tools where they exist. SlotoCash and Miami Club say deposit and time limits are available on request, and Silver Oak lists deposit limits, cool-off periods and self-exclusion. See deposit limits and gambling and money for practical steps.

Gambling record-keeping problems and how to fix them

The fix for most problems is the same habit: write things down the day they happen. A record made months later is far weaker than one made at the time. Our other online casino guides cover withdrawals, verification and bonuses in the same practical way.
