Before we can compute anyone's tax, we must answer a prior question: who, in law, is the taxpayer? Section 6 of the Income Tax Act [Chapter 23:06] answers it in a single sentence — income tax is "charged, levied and collected throughout Zimbabwe … in respect of the taxable income … received by or accrued to or in favour of any person during the year of assessment". The charge therefore fastens onto a "person", and the whole of the liability question turns on who counts as a person, when that person is within Zimbabwe's taxing jurisdiction, and who actually answers to ZIMRA for the tax when the person cannot act for itself.
The Act's definition of "person" in Section 2 is deliberately wide. It includes a company, a body of persons corporate or unincorporate (expressly excluding a partnership), a local or like authority, a deceased or insolvent estate, and — where income is held on a trust to which no beneficiary is yet entitled — the trust itself. The courts have confirmed it reaches a non-resident entity (Mota Engenharia Construction SA v ZIMRA, 22-SC-115). A separate definition of "taxpayer" then identifies the person actually in ZIMRA's hands: anyone in respect of whom an assessment is made, and anyone required to furnish a return. Liability to the charge (Section 6) and status as a taxpayer (assessment/return) are related but distinct ideas, and this lesson keeps them carefully apart.
Zimbabwe's system is source-based, so the residence of the person is not the primary trigger — the source of the income is. The practical effect is that residents and non-residents alike are liable on income from a source within (or deemed within) Zimbabwe; residence matters for particular rules (certain deemed-source and foreign-income provisions, some exemptions, and the mechanics of collection) rather than as the gateway to liability. A non-resident with Zimbabwean-source income is squarely a "person" liable under Section 6; the question is usually how the tax is collected from someone outside the country, which the Act solves through withholding taxes (Sections 26–34) and the representative-taxpayer machinery.
Different kinds of person are taxed through different mechanisms, and the bulk of this lesson is a careful walk through each: individuals (natural persons, taxed on the progressive PAYE/return basis), companies (separate legal persons taxed at the flat company rate, currently 25% under the Finance Act, and answering to ZIMRA through a public officer), partnerships (which are not persons — the partners are taxed individually on their shares), trusts and deceased/insolvent estates (taxed through a trustee or executor), and non-residents (taxed on Zimbabwean-source income, usually by withholding or through a Zimbabwean representative taxpayer).
The Act then supplies a crucial collection device: the representative taxpayer (Sections 53–56). Because many "persons" cannot personally deal with ZIMRA — a company is an abstraction, a deceased estate has no living owner, a non-resident is abroad, a minor is under disability — the Act designates a human or local stand-in who is assessed in a representative capacity and is responsible for the tax. The public officer of a company, the trustee of a trust or estate, an agent managing income, and the person remitting income to someone abroad are all representative taxpayers. They are liable to assessment in their own name (but only in the representative capacity), are entitled to an indemnity out of the represented person's assets (Section 55), and can become personally liable if they dispose of the income or funds while the tax is unpaid (Section 56).
Finally, liability does not stop at the primary taxpayer. The Act spreads responsibility to agents, public officers, and remitters, and backs it with personal-liability and recovery provisions, so that ZIMRA always has a local, reachable person answerable for the tax. This lesson grounds each of these rules in the Income Tax Act as updated to 27 May 2025, illustrates them with Zimbabwean case law printed in the Act itself (Afritrade International Ltd v ZIMRA, 21-SC-003; M Safaris (Pvt) Ltd v ZIMRA, 20-HH-331; Mota Engenharia, 22-SC-115), and works through computations for each class of taxpayer.
