Tanzania Adds 5% Tax on Betting Stakes, Stacking a Turnover Levy on Top of GGR

Tanzania's Ministry of Finance has proposed a 5% excise duty on the value of every bet placed, a turnover tax that the national assembly in Dodoma will debate as part of the 2026/27 budget. Finance Minister Khamis Mussa Omar tabled the measure on June 11, 2026, and the government intends it to take effect on July 1, the start of the new fiscal year. The duty falls on the stake itself, not on operator gross gaming revenue and not on player winnings, which makes it a materially different instrument from the tax models spreading across African betting markets.

That distinction matters because the 5% does not replace anything. It stacks. Tanzanian sports betting operators already pay 25% on gross gaming revenue, digital casinos pay 25% on revenue after winnings, and operators withhold 10% on the net winnings of Tanzanian players, according to the Tanzania Revenue Authority schedule reported by SiGMA. A turnover levy sits at the top of the funnel and is charged on money wagered before any of it is lost or won, so its effective bite on operator margins is far larger than the headline 5% suggests. The proposal covers land-based and online sports betting, land-based and online casino gaming, forty-machine slot operations, and virtual games.

The Finance Ministry projects the new duty will raise about TZS74.5 billion ($28.4 million) a year. Ten percent of that take, roughly TZS7.45 billion, will be remitted to the Gaming Board of Tanzania (GBT) to, in the ministry's words, "improve efficiency and regulation of gambling activities." Officials framed the levy as a response to problem gambling and to youth pulling away from productive work. A GBT spokesperson told iGaming Expert: "The board is not leaving any stone unturned in protecting the citizenry, and we have often reiterated that gaming should be treated as entertainment rather than mainstream behaviour."

The numbers behind a fast-growing, mobile-first market

Tanzanian gambling is small in dollar terms but compounding quickly. Gross win reached $463.3 million in 2025 and is projected to clear $1 billion by 2031, with online alone accounting for $918.9 million of that, per market figures cited by iGaming Business. The black market held just 4.5% of interactive gross win in 2025, a low leakage rate by regional standards that the new turnover tax now puts at risk. GBT tax collections have already climbed from TZS33.6 billion in 2016/17 to TZS170.4 billion in 2022/23, an average annual rise the regulator put at 407%, across 91 licensed operators employing more than 25,000 people.

The market runs on mobile money. M-Pesa, Airtel Money, and Tigo Pesa handle the overwhelming majority of deposits and withdrawals, and roughly 75% of participants are aged 18 to 34 in a country where more than 60% of people are under 35. Football-led sports betting is about 63% of activity. For affiliates, that profile is the core of the opportunity and the core of the tax risk: a young, mobile-first, low-stake-per-bet audience is the most sensitive to any levy charged on the stake rather than on the loss.

Why the precedent next door should worry Dodoma

The relevant comparison is not Senegal's 20% winnings tax through LONASE, South Africa's proposed 20% GGR regime, or the 5% withholding on payouts that Lagos State enacted in Nigeria. It is Kenya, the only East African market that has run a turnover tax experiment to its conclusion. In the 2017 Finance Bill, Kenya imposed a 35% tax on gambling revenue effective January 1, 2018, up from 7.5%. SportPesa, then the country's largest operator, pulled all club and federation sponsorship and exited the Kenyan market, and Betin followed. By 2020 the parliamentary finance committee acknowledged the higher rate had produced lower tax revenue, partly because operators could relocate to low-tax jurisdictions like Malta and the Isle of Man and still serve Kenyan punters. Kenya later settled on a 7.5% excise on stakes and a 20% withholding on winnings, collecting TZS-equivalent records only after it integrated operator systems with the revenue authority for daily remittance.

The lesson for Tanzania is specific. A stake tax is easy to announce and hard to absorb, because operators pass it to bettors as worse odds or shorter payouts, which pushes price-sensitive mobile users toward unlicensed offshore books. Tanzania starts from a strong channelization position with only 4.5% black market share, so it has more to lose from leakage than Kenya did. Affiliates and B2B suppliers reading the 2026/27 budget should watch two things: whether the duty survives parliamentary debate at 5% or gets cut the way Kenya's committee trimmed its stake tax under pressure, and whether GBT pairs the levy with real-time system integration. Without enforcement, a turnover tax mostly rewards the operators willing to book Tanzanian action from Malta. The duty is scheduled to take effect July 1, 2026.
