The individual — the natural person — is where the income-tax system both begins and ends. Companies and trusts are taxed as separate persons, but ultimately the income they generate flows to individuals, and it is on individuals that the system's defining feature, progressivity, operates. This lesson assembles everything the earlier lessons established about gross income, exemptions, deductions and rates and shows how they combine into a single personal income-tax computation for one human being for one year of assessment.
An individual is taxed under the Income Tax Act [Chapter 23:06] on the taxable income that the charging section, Section 6, brings to charge, calculated under Section 7 by applying the rates and credits fixed each year by the Finance Act [Chapter 23:04]. The mechanism is the familiar funnel established in the lesson on Foundations: gross income (Section 8) − exempt income (Section 14 / Third Schedule) = income; income − deductions (Section 15, limited by Section 16) = taxable income; taxable income × rate − credits = tax; + AIDS Levy. The defining feature for individuals is that all of a person's income from every source is aggregated into one taxable income and then taxed on a progressive scale — the more you earn, the higher the marginal rate on the top slice.
For the 2025 year of assessment the United States dollar annual rates run 0% on the first US$1,200, then 20%, 25%, 30%, 35%, and a top marginal rate of 40% on taxable income above US$36,000, with a parallel ZiG table (bands of 33,600 / 100,800 / 336,000 / 672,000 / 1,008,000) and an AIDS Levy of 3% added to the income tax. Because Zimbabwe taxes on a source basis (not worldwide residence), an individual is taxed on income from a Zimbabwean or deemed-Zimbabwean source; the deeming rules in Section 12 can, however, pull in some foreign employment, interest and dividend income of a person who is ordinarily resident here.
The individual income-tax computation differs from the corporate one in four structural ways. First, progressive rather than flat rates (companies pay a flat 25% for 2025; individuals climb a ladder). Second, personal tax credits are available only to individuals — the elderly persons' credit (aged 55+, US$900), the blind persons' credit (US$900), the mentally or physically disabled persons' credit (US$900), and the medical-expenses credit (50% of qualifying medical costs and medical-aid contributions). Third, the Finance Act distinguishes "taxable income from employment" (remuneration, as defined in the Thirteenth Schedule) from "taxable income from trade or investment" (everything else an individual earns), applying the rate scale to each — which matters when income is earned in different currencies. Fourth, collection differs by income type: tax on employment income is collected at source through PAYE (and is usually final under the Final Deduction System), while tax on an individual's trade, investment or rental income is collected through provisional tax (QPDs) under Section 72 — four instalments of 10%, 25%, 30% and 35% due on 25 March, 25 June, 25 September and 20 December.
Several rules shape how individuals are treated as a class. Zimbabwe assesses each individual separately — there is no joint assessment of spouses; each is taxed on their own income (with a narrow exception allowing an unused blind credit of a married blind person to transfer to the spouse). Anti-splitting rules in Section 10(3)–(6) prevent a parent from diverting income to a minor child or through a revocable settlement to escape the progression. Deceased and insolvent estates and persons under legal disability are taxed through representative taxpayers (see that lesson). And the currency-split rule in Section 4A requires tax on foreign-currency income to be paid in foreign currency, with separate USD and ZiG computations.
This lesson builds on Foundations (the charge, the funnel, the year of assessment), Gross Income and Specific Inclusions (what enters the computation), Exempt Income (what is removed), General and Specific Deductions (what is subtracted), Employment Income & PAYE (how employment income is taxed and collected), and Persons Liable to Income Tax (the individual as a "person"). It connects forward to Calculation of Income Tax Liability (the full worked mechanics), Partnerships (where individuals are taxed on profit shares), Representative Taxpayers, and Trusts and Deceased Estates.
