Under Section 8(1) of the Income Tax Act [Chapter 23:06], “gross income” is broadly defined as “the total amount, in cash or otherwise, received by or accrued to or in favor of a person in any year of assessment from a source within or deemed to be within Zimbabwe, excluding amounts proved by the taxpayer to be of a capital nature.” In simpler terms, any earnings of an income nature that originate from Zimbabwe (or are deemed to originate from Zimbabwe) count as gross income, unless the taxpayer can show that a particular receipt is capital (in which case it is excluded from gross income). Zimbabwe’s income tax system is source-based, meaning that income is taxed if it arises from a Zimbabwean source or a source deemed to be in Zimbabwe. (There are detailed deeming rules in Section 12 of the Act for certain cross-border situations to ensure such income is taxed in Zimbabwe, which we’ll touch on later.)
Finance Act amendments up to 2025/26: The core definition above has remained consistent, but Finance Acts have introduced specific inclusions and clarifications over time. For example, Section 8(3) was inserted by the Finance Act 1 of 2018 (effective 1 Jan 2018) to address advance payments: if an amount is received as a prepayment for goods, services or benefits to be provided in a future tax year, that amount is excluded from the current year’s gross income and will instead be taxed in the year the goods/services are delivered. This prevents immediate taxation of income received in advance for future obligations. Additionally, specific items have been added to the gross income definition through Finance Act amendments – for instance, the value of fringe benefits (advantages or benefits from employment) is expressly included under Section 8(1)(f) and valued per rules (as discussed below), and employee share option gains are included under Section 8(1)(t). These inclusions, added in past amendments (e.g. taxing share option benefits around 2009), ensure that non-cash employment rewards are taxed as part of gross income. Overall, the Finance Act each year also updates rates and credits, but the fundamental meaning of “gross income” – total taxable receipts from Zimbabwean sources, excluding capital – remains as stated in the Act.
