How Betting Winnings Are Taxed in Tanzania
Tanzania taxes betting winnings at source, and since 1 July 2026 the rate is 15% of net winnings for every game type. The tax is not charged on the full payout: the stake comes off first, and the licensed operator withholds the tax before paying you. This guide explains what net winnings are, why some pages still say 12% or 13%, and what Amina in Dodoma would actually receive from a 100,000 TZS payout.
The short answer: Betting winnings in Tanzania are taxed at 15% of net winnings from 1 July 2026, not on the full payout. The operator withholds it before paying you. Some pages still quote 12% or 13%, which are the older rates.

The tax is on net winnings, not the payout
The base is the winning amount minus the stake. A 10,000 TZS bet that returns 100,000 TZS has 90,000 TZS of net winnings, so the 15% tax is 13,500 TZS and the net payout is 86,500 TZS. The tax is not 15,000 TZS on the full payout, and it is not charged on the stake you got back.
The Sports Betting Rules 2016 define the return field as net winnings — winning amount minus winning stake — and require the ticket to show the expected winnings, the tax and the net expected winnings. TRA's gaming-tax page uses the same phrase. If an operator quotes a tax figure on the gross payout, the base is wrong.
The rate is 15% from 1 July 2026
Finance Act 2026 deleted s.34(2) of the Gaming Act, which had set lower rates for land-based casinos and sports betting. The 15% general rate in s.34(1) now applies to every activity the Act covers.
| Period | Sports betting | Land-based casino | Other games |
|---|---|---|---|
| 1 Jul 2022 – 30 Jun 2025 | 10% | 12% | 15% |
| 1 Jul 2025 – 30 Jun 2026 | 12% | 13% | 15% |
| From 1 Jul 2026 | 15% | 15% | 15% |
Why some pages still say 12% or 13%
Those were the reduced rates for sports betting and land-based casinos up to 30 June 2026. They are still visible on TRA's gaming-tax page and on several betting-tax calculators, including one pan-African tool that uses 12% for Tanzania. For payments from 1 July 2026, the Act gives 15% for every game type.
The safest check is the payment date, not the date the bet was placed: the rate in force when the operator pays the winning is the one that applies. If an operator withholds 12% on a payment made after 30 June 2026, it has under-withheld, and the operator is liable for the difference.
The 5% stake tax never happened
The 2026/27 budget proposed a 5% excise on the value of bets, but it was withdrawn before the Finance Act 2026 was enacted. There is no 5% charge on placing a bet, and a calculator that adds one is describing a proposal rather than the law.
Who withholds it, and when
The licensed operator is the withholding agent. It deducts the tax when it pays the winning, remits it to TRA by the 7th of the following month, and files a return by the 15th. The player receives the net amount; there is no separate payment to make.
Winnings that have borne this tax are not liable to income tax under s.34(3), so the 15% withholding is the final tax on the winning. A payslip-style income tax calculation on top would double-count it.
A worked example: Amina's 100,000 TZS payout in Dodoma
A sports betting punter stakes 10,000 TZS and receives 100,000 TZS in total. Net winnings are 90,000 TZS (100,000 − 10,000), so the 15% gaming tax is 13,500 TZS and the net payout is 86,500 TZS. Winnings that have borne this tax are not liable to income tax.
Amina staked 10,000 TZS and the bet returned 100,000 TZS. The operator withholds 13,500 TZS, so she receives 86,500 TZS. The effective tax on the payout is 13.5%; the effective tax on the net winnings is 15%.
Common mistakes
The errors that most often change the answer:
- Applying 15% to the full payout instead of the net winnings. The stake comes off first, which lowers the tax.
- Using the old 12% sports-betting or 13% land-casino rate for a payment made after 30 June 2026.
- Adding income tax on top of the winnings tax. Winnings that have borne the gaming tax are exempt.
- Adding the withdrawn 5% stake excise, or treating a losing bet as taxable. A loss has no net winnings.
Reading the ticket
The Sports Betting Rules require a ticket to show the expected winnings, the tax and the net expected winnings. That is the check a bettor can make at the counter: the tax line should be 15% of the expected winnings minus the stake, and the net line should be the amount the operator will pay. A ticket that shows only a total, with no tax line, does not let the bettor verify the deduction and is worth querying before the race or match starts.

How Betting Winnings Are Taxed in Tanzania FAQs
How much tax is taken from betting winnings in Tanzania?
15% of net winnings from 1 July 2026. The operator withholds it before paying the winning; on a 100,000 TZS payout from a 10,000 TZS stake, the tax is 13,500 TZS.
Is the 15% charged on the payout or on the profit?
On the profit: total payout minus the stake. The tax is 15% of that net figure, not 15% of the amount returned.
Why do some pages still say 12%?
12% was the sports-betting rate up to 30 June 2026. Finance Act 2026 deleted the reduced-rate subsection and the general 15% applies from 1 July 2026.
Do I pay income tax on betting winnings in Tanzania?
No. Winnings that have borne the gaming tax are not liable to income tax under s.34(3) of the Gaming Act; the 15% withholding is the final tax.
Was the 5% tax on bets ever introduced?
No. It was proposed in the 2026/27 budget and withdrawn before the Finance Act 2026 was enacted. No stake excise is in force.
What happens if my winnings are less than my stake?
There is no net winning, so no gaming tax is due. A losing bet is not taxed, and the loss is not carried forward as a credit.
Who pays the tax — the bettor or the operator?
The tax is the player's, but the operator withholds and remits it. The player receives the net payout; the operator is liable if it fails to withhold.
