Zimbabwe operates a source-based income tax system, not a residence-based one. The gateway to the charge is built into the definition of gross income in Section 8(1) of the Income Tax Act [Chapter 23:06]: only an amount received or accrued "from a source within or deemed to be within Zimbabwe" enters the tax net. Residence is therefore not the primary connecting factor the way it is in many other countries — a non-resident with a Zimbabwean source is taxed, and a resident with a purely foreign source is, as a starting point, outside the charge. This single design choice drives almost every rule in this lesson.
Because a pure source test would let mobile income and modern cross-border arrangements escape, the Act bolts on a series of deeming provisions that pull specified foreign-flavoured amounts into a Zimbabwean source. The central catalogue is Section 12 ("Circumstances in which amounts are deemed to have accrued from sources within Zimbabwe"), supported by Section 10 (amounts deemed to have accrued even if not yet paid) and Section 11 (income from assets in deceased and insolvent estates). Several of the Section 12 deeming rules are switched on only when the taxpayer is "ordinarily resident" in Zimbabwe — so residence re-enters the system as a secondary factor that widens the net for residents, even though it is not the gateway.
Residence does the heaviest lifting for companies. Under Section 19A (inserted by the Finance Act (No. 2) of 2017, backdated to 1 January 2017) a company not resident in Zimbabwe is liable to Zimbabwean tax only if it carries on business here through a permanent establishment, and then only on the taxable income attributable to that permanent establishment. Section 19B defines "permanent establishment" (a fixed place of business, or a dependent agent who habitually concludes contracts), with the usual independent-agent and preparatory/auxiliary carve-outs. A company's residence itself turns on the common-law central management and control test, reflected in the Act's deeming rule that a company is "ordinarily resident in the state or territory in which its central management and control is situated."
Key defined terms you must hold precisely: "source" (an originating cause located somewhere — a question of fact, not where payment is made); "deemed source" (a statutory override that fixes a Zimbabwean source regardless of true origin); "ordinarily resident" (a common-law concept of habitual, settled residence — there is no statutory definition for individuals, so it is decided on the facts); and "resident"/"non-resident" as used in particular provisions. A recurring trap is Section 12(1)(c), which deems a Zimbabwe source for employment services an ordinarily resident person performs abroad during a "temporary absence" — defined as absence not exceeding 183 days in aggregate in the year of assessment.
The rates that attach once an amount is inside the net are set by the annual Finance Act [Chapter 23:04] (the "charging Act"): for the 2025 year of assessment, companies and trusts are taxed at 25% (Finance Act Section 14(2)(c)), individuals on a sliding scale up to 40% on taxable income above US$36,000, and a foreign-domiciled satellite-broadcasting or e-commerce operator caught by Section 12(6)/(7) and Section 12A pays 5% of its Zimbabwean revenue (Finance Act Section 14(2)(k)) once that revenue exceeds US$500,000 in the year. An AIDS Levy surcharge is added to the income tax payable.
Finally, where Zimbabwe has concluded a Double Taxation Agreement (DTA), the treaty overlays these domestic rules — reducing source-country rates, raising the permanent-establishment threshold and supplying residence tie-breakers. Crucially, you engage the domestic charging and source rules first, and only then apply the treaty as relief (see the dedicated lesson on Double Taxation Agreements). DTA relief in Zimbabwe is delivered through Sections 91 to 93 of the Income Tax Act.
