Proving betting winnings to your bank: what it wants and which documents help
Payouts from several bookmakers land on your current account, and suddenly your bank wants to know where the money comes from. That is not an accusation; it is a legal duty of the bank. This guide explains why it asks, which documents usually settle it quickly, and how a simple record keeps you ready. It is a different check from the one a bookmaker makes, which is covered in source of funds checks.

This page describes the general position in Austria and Slovakia as of October 2026. Each bank applies its own rules. If your account has been restricted or large amounts are involved, get advice, for example from a consumer advice centre.
In short
- Banks must monitor your account under anti-money-laundering law and, where needed, ask about the source of the money.
- The best answer is a short explanation plus evidence: the bookmakers' transaction histories, your bank statements and a simple summary of all deposits and withdrawals.
- This is not the same as a bookmaker asking about your source of funds. That check is explained in source of funds checks.
Why the bank asks
Banks are obliged entities under the EU anti-money-laundering directive (EU) 2015/849. It requires "ongoing monitoring of the business relationship": the bank must check that your transactions fit what it knows about you, including, where necessary, the source of funds. Austria implements this in the Financial Markets Anti-Money Laundering Act (FM-GwG, § 6), Slovakia in Act No. 297/2008. From 10 July 2027, the EU Anti-Money Laundering Regulation (EU) 2024/1624 applies directly as well.
In practice, the bank's software flags patterns that differ from your usual activity. The bank then writes to you, usually through online banking or by letter, and asks for an explanation and evidence. Until that is settled, it can hold individual payments or restrict the account.
Worth knowing: if a bank has filed a suspicious activity report, the law forbids it to tell you (in Austria § 20 FM-GwG). Short, general requests are therefore normal and not a sign that anyone suspects you of anything.
What stands out to a bank
With sure bets you move money between several betting accounts. On a statement that looks different from someone who stakes €20 on a match once a month:
- Payments from several bookmakers, often in odd amounts and at short intervals.
- High turnover compared with your salary: deposits and withdrawals that together are a multiple of your income.
- Fast back and forth: money goes to bookmaker A, comes back from bookmaker B, goes out again.
- Detours through e-wallets or crypto exchanges, where the bank can't see the origin.
- Operators without a known licence or based outside the EU.
None of this is forbidden. It simply isn't understandable for the bank without an explanation.
Documents that help
| Document | What it shows | Where you get it |
|---|---|---|
| Transaction history per bookmaker | Every deposit and withdrawal with date and amount, in your name | Your bookmaker account under "transactions" or "account history"; otherwise ask support |
| Bet history (export or printout) | That the payouts come from bets | Your bookmaker account; many send a file on request |
| Your bank statements | That deposits came from your own account, for example from your salary | Online banking as PDF |
| Your own summary | Deposits, withdrawals and net result per bookmaker for the period, on one page | Your spreadsheet or the CSV export of a bet tracker |
| Licence details of the bookmakers | That they are regulated companies | The bookmaker's imprint or footer |
| Payslip or pension statement | Where your starting money came from | Employer, pension insurer |
A bank usually doesn't want to see 400 bet slips. It wants to understand where the money comes from and that the totals add up. One page of figures per bookmaker, with the bookmakers' histories attached as evidence, is usually enough. How to keep such a record from the start is in bet tracking.
Worked example: gross flows and the result
Banks see gross amounts. What is left for you is far smaller. A simplified example over three months:
| Bookmaker | Deposits | Withdrawals | Net |
|---|---|---|---|
| Bookmaker A | €500 | €780 | +€280 |
| Bookmaker B | €400 | €0 | −€400 |
| Bookmaker C | €300 | €540 | +€240 |
| Bookmaker D | €300 | €300 | €0 |
| Total | €1,500 | €1,620 | +€120 |
The bank sees €1,620 coming in from bookmakers. Your result across all accounts is +€120. At bookmaker B you only lost, because that is where the opposite legs of your sure bets were. This summary answers the bank's question: the money came from your salary, went round your own betting accounts and came back with a small plus.
Assumptions: simplified example, no balance left on any betting account at the end. Real results vary and can be negative.
How to reply
- Check it's genuine. Read the request in online banking or call the number on your bank card. Don't click links in emails or text messages that ask for login details.
- Note the deadline and scope. Which transactions, which period, by when?
- Write a short explanation, for example: "The incoming payments from bookmakers A, C and D are withdrawals from sports betting accounts in my name. I funded them from this account, from my salary. Attached are the bookmakers' transaction histories and a summary per bookmaker. My net result for the period is +€120."
- Attach the evidence, as complete PDFs. Send what is asked for, not your whole betting history.
- Get receipt confirmed and note the date. If the bank follows up, answer factually and with numbers.
If a bank closes your account anyway, EU law gives consumers a right to a basic payment account at another bank (Directive 2014/92/EU, implemented in Austria and Slovakia). In Slovakia, Národná banka Slovenska handles consumer complaints about banks; in Austria, the Arbeiterkammer advises consumers free of charge.
And tax?
The bank's question is about money laundering, not tax. The same records still help if the tax office ever asks:
- Austria: winnings from private sports betting are generally not subject to income tax; very large, business-like betting can be assessed differently. See Austria betting tax.
- Slovakia: winnings from bookmakers licensed by ÚRHH are generally exempt; winnings from foreign or unlicensed operators may be taxable. See Slovakia betting tax.
The general picture is in tax and legality.
What to avoid
- Splitting deposits artificially to stay under a threshold you suspect exists. That is exactly the pattern anti-money-laundering systems look for.
- Using other people's accounts or cards, including a partner's or parents'. It breaks bookmakers' terms and makes every explanation harder.
- Incomplete or polished figures. A plain summary that includes losses is better than a story that doesn't match the numbers.
- Ignoring the request. If you don't answer, the bank may end the relationship.
If the bank declines payments to bookmakers in the first place, that is a separate issue: see bank blocks gambling payments.
Be ready before anyone asks
It is easiest when you already have the numbers. Keep one line per bookmaker and enter every deposit and withdrawal. In ArbVantage, the Tracking page keeps balances, deposits and withdrawals per bookmaker, and the bet tracker exports your bets as a CSV file. That doesn't replace the bookmakers' own histories, but it gives you the summary for the bank in minutes. A separate current account used only for betting makes it even clearer.
Frequently asked questions
Can my bank restrict my account because of payments from bookmakers?
Yes. While it checks the source of funds under anti-money-laundering law, a bank may hold individual payments or restrict the account. A short explanation with evidence usually settles it quickly.
Which documents does the bank want to see?
Usually the bookmakers' transaction histories, your bank statements and a simple summary of deposits and withdrawals per bookmaker. Send what is asked for, complete and as PDFs.
Is this the same as a bookmaker's source of funds check?
No. Here your bank asks about money moving through your current account. A source of funds check comes from the bookmaker and asks where the money you deposited there came from. The same records help with both.
Why won't the bank tell me exactly what it is about?
If a bank has filed a suspicious activity report, the law forbids it to tell you. General, brief requests are therefore normal and not an accusation.
