Tanzania taxes residents on worldwide income and non-residents on Tanzania-source income only. Tanzania operates a self-assessment system for corporate tax, with the Tanzania Revenue Authority conducting post-filing review.
Tanzania's tax year runs the calendar year, with an annual returns deadline of 31 January of the following year. Note the East African Community (Kenya, Uganda, Tanzania, Rwanda, Burundi) implemented coordinated customs and duty changes effective 1 July 2026.
Tanzania's headline corporate income tax (CIT) rate is 30%.
The headline personal income tax (PIT) rate is residents 30%; non-residents 15-30%.
The standard VAT/GST (or equivalent consumption tax) rate is 18% mainland (16% for certain B2C); 15-18% Zanzibar.
An individual is a Tanzanian tax resident if they have a permanent home in Tanzania and visit during the year, or - lacking a permanent home - are present in Tanzania 183 days in the year, or average 122 days per year across the current and preceding two years. Residents are taxed on worldwide income; non-residents only on Tanzania-source income.
A non-Tanzanian entity has a Tanzania permanent establishment through a fixed place of business or a dependent agent habitually concluding contracts in Tanzania on the entity's behalf, following the OECD Model Treaty definition as applied under Tanzanian domestic law and any applicable tax treaty.
Tanzania has genuine CFC provisions: the attributable income (less distributions) of a controlled foreign trust or corporation is included in the income of the Tanzanian "controlling person." A separate anti-avoidance measure lets the Commissioner deem 30% of an entity's profits as distributed if no distribution occurs within 12 months after the accounting period ends - resident entities already covered under the CFC rules are exempted from this deemed-distribution provision to avoid double-counting.
Interest deductibility for an "exempt-controlled resident entity" (a resident entity where 25% or more of underlying ownership is held by tax-exempt bodies, approved retirement funds, charities, non-residents, or their associates) is restricted where the debt-to-equity ratio exceeds 7:3 (equivalent to roughly 2.33:1). The definition of "equity" was expanded to include positive retained earnings (previously limited to paid-up share capital only). Non-deductible interest amounts can be carried forward.
Tanzania does not use an elective check-the-box classification system; entity classification generally follows the entity's actual legal characteristics. Tanzania does not have a comprehensive ATAD2-style anti-hybrid regime.
No foreign bank account or foreign financial asset reporting regime exists requiring residents to separately disclose foreign accounts; foreign income is reported through the standard annual tax return.
Tanzania does not provide a broad participation exemption for foreign dividends in the European sense; relief from double taxation is available primarily through Tanzania's foreign tax credit system, coordinated against Tanzania's own genuine CFC regime to avoid double-counting attributed profits.
Tanzania has a foreign tax credit mechanism for foreign tax paid on foreign-source income also taxed in Tanzania, capped at the Tanzanian tax otherwise due on that income.
Tanzania's treaty network is limited, with double tax treaties in force with Canada, Denmark, Finland, India, Italy, Norway, South Africa, Sweden, and Zambia.
