Yes - online betting is legal and regulated in Tanzania. The Gaming Board of Tanzania (GBT) licenses online sportsbooks, casinos and lotteries under the Gaming Act (Cap. 41), and only GBT-licensed operators may legally serve Tanzanian players. Betting is an 18+ activity, winnings are taxed at source (12% on sports betting, 13% on land-based casinos under the Finance Act 2025), and the everyday payment rail is mobile money in Tanzanian Shillings. Crypto gambling, by contrast, sits in an unregulated grey zone with no licensed local framework.

Tanzania is one of Africa’s earliest regulated betting markets. The Gaming Board of Tanzania (GBT), established under the Gaming Act (Cap. 41), which took effect on 1 July 2003, is the sole authority that issues gambling licences. It oversees casinos, sports betting, SMS and national lotteries, slots and online gaming. Remote operations are governed by internet-gaming regulations and administered through the GBT’s GLICA licensing and compliance system. Licences are granted for one year and renewed annually, and online operations require the appropriate licence with their own technical and compliance criteria. The GBT is the only body that may issue gaming licences in Tanzania.

Licensed vs offshore operators

Plenty of well-known brands hold GBT licences and operate legally, including SportPesa, Betway, Premier Bet, M-Bet, Gal Sport Betting (GSB), Parimatch, Betika, 22Bet, 888bet and Mkeka Bet. Choosing a GBT-licensed operator matters: only licensed sites offer local player protection, verified payouts and dispute recourse through the regulator. Offshore sites that accept Tanzanian players without a GBT licence operate outside the law and give you no local safety net if something goes wrong.

Payments locals actually use

The smoothest experience is in Tanzanian Shillings via mobile money, which is near-universal:

Deposits can start from roughly 1,000 TZS, and payouts flow straight back to your wallet. Cards and bank transfers exist but wallets are the default.

Not in any licensed sense. The Bank of Tanzania has issued public notices cautioning the public against trading or using virtual currencies and reiterating that the Tanzanian Shilling is the only legal tender. Cryptocurrencies are unregulated and not recognised as legal tender, and there is no licensed crypto-casino regime. The central bank has more recently opened a fintech regulatory sandbox - including a pilot of a TZS-pegged stablecoin - which signals it is studying the space, but no crypto-gambling framework exists. Practically: licensed GBT operators deal in TZS mobile money, not crypto. Any crypto gambling happens on unregulated offshore platforms - outside Tanzanian law and with zero local recourse.

Tax on your winnings

Tanzania taxes winnings at source, so you receive net payouts. Under the Gaming Act as amended by the Finance Act 2025 (effective 1 July 2025):

  • Sports-betting winnings: 12% of the amount or value won
  • Land-based casino winnings: 13%

Operators withhold and remit this to the Tanzania Revenue Authority (TRA). Note that for the 2026/27 budget the government proposed a 5% excise duty on the value of each betting stake, but that measure was removed from the final Finance Act 2026 by Parliament (June 2026) and did not take effect. Tax rules change with each Finance Act, so confirm current figures with the TRA or the GBT.

Safer gambling and help

GBT-licensed sites are expected to offer responsible-gambling tools such as self-exclusion, deposit and loss limits, and time-outs. All betting is 18+. Tanzania has no dedicated national gambling helpline, but the GBT provides responsible-gambling guidance and a voluntary self-exclusion process through its GLICA portal (glica.gamingboard.go.tz). Independent counselling is offered by Mind Garden Firm, and international directories such as findahelpline.com list further options.

18+. Gamble responsibly. Only bet what you can afford to lose; if it stops being fun, use self-exclusion or seek help.
