You win 10,000 shillings. The operator pays you 8,000. Nothing went wrong, nobody cheated you, and no support ticket will get the rest back — a withholding tax was deducted before the money reached your account.
Almost no gambling site tells you this before you play. It is not a small detail: in the markets where it applies, it is the single largest deduction from your winnings, larger than the house edge on most games.
Here is what each African market we cover actually does.
The short answer
| Country | Deducted from your winnings |
|---|---|
| Kenya | 20%, withheld by the operator before payout |
| Uganda | 15%, withheld at payout |
| Tanzania | Withheld by the operator; the rate is set annually in the Finance Act |
| Zambia | Withholding applies to winnings from licensed operators |
| Zimbabwe | Withholding applies to winnings from licensed operators |
| Ghana | None — the 10% withholding tax was removed in 2025 |
| Nigeria | None on individual winnings |
| South Africa | None for recreational players |
| Cameroon | None — the tax sits on the operator, not on you |
| Senegal | Applies to large lottery prizes through the state operator |
| Morocco | Applies to large lottery and betting prizes |
Two things stand out. Neighbouring countries disagree completely — a Kenyan player loses a fifth of every win while a Nigerian loses nothing. And Ghana went from 10% to zero in a single budget, which tells you how durable any of these numbers are.
Withholding is not the same as owing
This is the distinction that costs people money, so it is worth being precise about.
Withholding means somebody else takes the tax out before paying you. You never touch the money, you file nothing, and there is no decision to make. Kenya and Uganda work this way — the licensed operator is legally required to deduct and remit it.
Assessment means the tax is your responsibility to declare. South Africa’s position on recreational players is that winnings are not taxed, but income from professional gambling may be assessed — that is a question about you, not about the game.
The practical consequence: in a withholding country, you cannot get the deduction back by not mentioning it. It is already gone. In an assessment country, silence is a decision with consequences.
The offshore gap, honestly
Every rate above applies to operators licensed in that country. That is where the obligation sits.
An international casino licensed in Curaçao or Anjouan has no relationship with the Kenya Revenue Authority or the Uganda Revenue Authority. It deducts nothing. Your withdrawal arrives whole.
It is worth being clear about what that does and does not mean:
- It does mean your payout is not reduced at source
- It does not mean the winnings are outside your country’s tax law
- It does mean any obligation that exists is now yours to work out, with no paperwork from the operator to work from
We are not going to tell you what to do with that, because the answer depends on your country’s law and your own circumstances, and we are not qualified to give tax advice. What we will say is that “the casino did not deduct anything” is a statement about the casino, not about your position.
It is a tax on winning, not on profit
This is the part that surprises people, and it is worth stating carefully.
The house edge is charged on what you stake. A slot returning 96% costs you about 4% of everything you put through it, win or lose. Withholding is charged on the other side — on money coming back to you.
The two are not alternatives. They stack. A losing session is taxed at zero and still costs you the edge; a winning session pays the edge on the way in and the withholding on the way out. Over any stretch of play, the deduction is not a slice of your profit — it is a slice of your returns, and there is no arrangement of stakes that avoids it.
What the withholding is actually calculated on — the full payout, or the payout less the stake for that bet — is defined by each country’s tax law, and those definitions have been amended more than once. Read the payout breakdown on your own statement rather than trusting a rate quoted on any site, including this one. That document is the authority on what happened to your money; we are not.
This is why the honest comparison between a licensed Kenyan operator and an offshore one is not a comparison of bonus sizes. One deducts a fifth at source and gives you a regulator who will hear a complaint. The other deducts nothing and gives you a Curaçao licence, which — as we set out in casino licences explained — offers very little recourse if a payout is refused.
That is a real trade-off, and different players will weigh it differently. It is not the trade-off most affiliate sites present.
The rates move
Ghana’s 10% withholding tax on winnings was introduced, defended, and then removed in 2025. Tanzania’s rate is set annually in the Finance Act, which means it is a budget decision rather than a fixed feature. Nigeria moved gaming regulation from federal to state level after a 2024 Supreme Court ruling, and state-level authority means state-level divergence over time.
Anything you read about African gambling tax that carries no date is worth ignoring. This page carries one, and we review it — but a budget statement can make it wrong the week after we do.
Before you assume the number
Three checks worth doing, in order:
- Look at the payout breakdown, not the balance. Licensed operators that withhold are generally required to show the deduction. If your payout is smaller than your win and the difference is a round percentage, that is what happened.
- Check whether the operator is licensed where you live. It determines whether withholding applies at all. Our country pages list the regulator for each market we cover.
- Verify your account before you win, not after. Withholding and verification are separate problems, but they produce the same symptom — money that has not arrived. KYC verification explains why the second one is avoidable.
Where this leaves you
If you play from Kenya or Uganda with a locally licensed operator, price the deduction in before you decide a session was worth it. The full position for each is on our Kenya and Uganda pages — Uganda also has the highest minimum age of any market we cover, at 25.
If you play from Ghana or Nigeria, no personal deduction applies to your winnings today. Ghana’s case is recent enough to be worth re-checking; see Ghana and our Nigerian casino comparison.
If you play from South Africa, recreational winnings are not taxed, but the law on online casino play itself is the more consequential question.
And wherever you are: a tax rate is a reason to play smaller, never a reason to play more to make it back. If that thought has occurred to you, the warning signs page is short and worth two minutes.
