Gambling with crypto: Restricted.

• Minimum age: 18. Applies online and in gaming premises ↗

You must be 18 to gamble online in Tanzania, for online casino, sports betting and lottery alike.

• Tax on winnings: 15%. Withheld by the operator on each winning paid; no tax-free threshold ↗

The licensee withholds the tax when it pays each winning and remits it by the seventh day of the following month. Gaming Act R.E. 2023 s. 34(1) sets 15%; the Finance Act 2025 s. 41(a) set 12% for sports betting (from 10%) and 13% for land-based casino (from 12%) from 1 July 2025, and earmarked part of those two collections for the AIDS Trust Fund and the Universal Health Insurance Fund. The Finance Act 2026 s. 16 deleted s. 34(2) from 1 July 2026, so the 15% in s. 34(1) applies to all winnings; the TRA web page still shows the old rates. Winnings so taxed are not liable to income tax.

Rate: 15% on every winning from 1 July 2026 (the 12% sports-betting and 13% land-based casino rates of 1 July 2025 - 30 June 2026 no longer apply); withheld by the operator at payout, no tax-free threshold.

41 online licensees in Tanzania, as of 4 Nov 2026.

Always verify a casino holds a valid Gaming Board of Tanzania (GBT) licence before depositing. Check the official register before signing up.

The official register of licensed sitesGaming Board of Tanzania (GBT)'s website

Prominent operators in Tanzania

If a site isn't on the regulator's licensee register, ask the regulator before you play: an unlisted site is usually not licensed here (a register can lag behind a new licence). An unlicensed site is outside the regulator's supervision, so you cannot complain to the regulator about it.

• ✓
  Check the licence

  The Gaming Board lists every licensed operator by product, online and land-based. A licensed site shows its licence number and date of issue on its homepage, with a statement that the Board regulates it; a betting site shows them on every page.

• ✓
  Set your own limits

  Licensed operators must let you set a deposit or wager limit; raising or removing it takes effect only after seven days.

• ✓
  Help: 0800 110 051

  The Gaming Board’s toll-free number. Radio adverts must end with it, television adverts with celebrity commentary must mention it, and SMS or electronic adverts over 160 characters must include it.

• Deposit or wager limit: Your choice. The site must let you set one; changing or removing it takes effect only after seven days ↗
• Complaints: 14 days. The operator must resolve and answer within 14 days; you can then complain to the Board within 14 days ↗

• Myth

  Small winnings are tax-free.
  Reality

  No threshold exists: every winning is taxed at source, at 15% on all games from 1 July 2026 (12% on sports bets until 30 June 2026).

• Myth

  Self-exclusion at one site covers them all.
  Reality

  It does not: exclusion runs through each operator’s own system, for at least six months.
