Tanzania and Qatar Sign Tax Treaty to End Double Taxation for Investors
Tanzania · EXPAT
Key Facts
- —The country Tanzania, on Africa’s Indian Ocean coast, has about 70.5 million people, roughly Britain’s population. Its economy was about US$90 billion in 2025, less than a fortieth of Britain’s (World Bank).
- —Why it matters Qatar, a Gulf state of about 3 million people, is a leading exporter of liquefied natural gas (LNG). Its US$216 billion economy has capital to invest abroad.
- —Why now Tanzania is courting Gulf money for gas, ports, farming and tourism. Prime Minister Mwigulu Nchemba was in Doha days before the signing, inviting Qatari businesses to invest.
- —What happened Finance ministers Khamis Mussa Omar and Ali bin Ahmed Al Kuwari signed a double-taxation treaty in Doha on Tuesday 29 September 2026.
- —The numbers Tanzania has such treaties in force with only nine countries. Treaties signed with the United Arab Emirates, Oman, Türkiye and Singapore since 2022 are not yet in force.
- —What it means for you Nothing changes yet for firms or expatriates earning in both countries. Withholding rates on dividends, interest and royalties will be known only when the treaty text is published.
- —Still open No treaty text, entry-into-force date or ratification timetable has been published. Neither government has put a figure on the investment it expects.
Tanzania, a fast-growing East African economy, has signed a treaty with gas-rich Qatar so that cross-border income is not taxed twice. It is a technical step, but it matters to anyone moving money between the two.
The Tanzania Qatar tax pact was signed in Doha on Tuesday 29 September 2026. Tanzania has about 70 million people on Africa’s Indian Ocean coast; Qatar is a small, gas-rich Gulf state.
Tanzania’s finance minister, Khamis Mussa Omar, signed with his Qatari counterpart, Ali bin Ahmed Al Kuwari. They met at the annual meeting of the Asian Infrastructure Investment Bank (AIIB), a Beijing-based multilateral lender.
What the agreement actually does
A double-taxation agreement decides which country may tax a given type of income, and how the other country gives relief. It lets an investor or employee avoid paying full tax on the same earnings twice.
The treaty also provides for the two tax authorities to share information and cooperate. Both governments said this would help fight tax evasion and avoidance while protecting their revenues.
“By eliminating double taxation, the agreement will promote international trade, investment and business activities,” Omar said, according to Tanzania’s The Citizen newspaper. He added that it would create “a more transparent and predictable environment for investors.”
Al Kuwari called Tanzania an important economic partner for Qatar. He said removing double-taxation barriers would help investment and capital move between the two countries.
A deal more than a year in the making
Negotiators finished the draft and initialled it in August 2025. At that stage, Qatar’s General Tax Authority said it covered dividends, interest, royalties, joint ventures and international air and sea transport.
Those are the main channels through which large projects are financed and run. Initialling is not a signature, so Tuesday’s ceremony completes the negotiation phase.
The signing followed a visit to Doha by Tanzania’s prime minister, Mwigulu Nchemba. On 27 September he met Qatari business leaders and invited them to invest in Tanzania.
The sectors on offer included gas, farming, food processing, minerals, livestock, tourism, ports, logistics and special economic zones. The two governments also signed a memorandum of understanding (MoU) to set up regular political consultations.
Where Qatari money could go
Qatar is already active in Tanzania through the Qatar Investment Authority (QIA), its sovereign wealth fund, and the Qatar Fund for Development. Al Kuwari said both take part in projects in the country.
He singled out oil and gas as an area where clearer tax rules could support existing and future projects. Tanzania holds large offshore natural-gas reserves that it has long hoped to develop into a liquefied gas industry.
Ports and aviation are another natural fit, since the treaty draft referred to air and maritime transport. Qatar Airways already flies to Tanzania, including to Zanzibar, the semi-autonomous islands off the coast.
Neither government has published figures on bilateral trade, Qatar’s investment stock in Tanzania or the investment the treaty is expected to bring. Claims about its economic impact therefore remain untested.
How Tanzania’s treaty network compares
Tanzania has double-taxation treaties in force with only nine countries: Canada, Denmark, Finland, India, Italy, Norway, South Africa, Sweden and Zambia. That is a thin network for an economy seeking foreign capital.
It also signed treaties, not yet in force, with the United Arab Emirates (2022), Oman (2024), Türkiye (May 2026) and Singapore (June 2026). The Qatar treaty joins that queue.
All five recent signings are with Gulf, Turkish or Asian partners, a sign of where Tanzania now looks for capital. The Rio Times follows these shifts in its Africa: The New Scramble coverage.
What expatriates and investors should watch
The most important next step is publication of the treaty text. Only then will companies and individuals know the withholding rates for dividends, interest and royalties, and the rules on capital gains.
Both countries must also complete their domestic approval procedures and exchange notifications. Only then does a treaty enter into force, and its provisions usually apply from a later tax year.
No such date has been announced, so existing tax obligations stay unchanged for now. Expatriates with income in both countries should follow guidance from the Tanzania Revenue Authority and Qatar’s General Tax Authority.
The information-sharing clauses cut both ways. They make cross-border business more predictable, but they also mean the two tax authorities will see more of each other’s data.
Why it matters beyond the tax code
A tax treaty does not by itself create investment. It does not lower customs duties, fix port bottlenecks or remove currency risk for investors.
What it does is remove one structural obstacle that makes investors hesitate. Whether Qatari capital actually follows into Tanzanian gas, ports and farms is the real test.
