Zimbabwe's ordinary income tax, charged under Sections 6 and 7 of the Income Tax Act [Chapter 23:06], assumes a particular kind of taxpayer: one who keeps books of account, computes a taxable income by subtracting allowable deductions from gross income, files a return, and is assessed by the Commissioner. That model — which you studied in Persons Liable to Income Tax (itcliablepersons), Allowable Deductions (itcdeductions) and Calculation of Income Tax (itccalculation) — works well for employers, companies and registered businesses. It breaks down completely for the very large part of the Zimbabwean economy that is informal: the commuter-omnibus operator taking cash fares, the flea-market vendor, the backyard welder, the cross-border trader, the small-scale gold panner. These operators keep no records, hold no business bank account, and cannot realistically be audited. Left alone, they would be both a revenue leak and an equity problem, because the formally employed and the registered corporates would carry a burden the informal sector escaped.
Presumptive tax is the system's answer. Instead of taxing proven profit, it taxes a presumed level of income inferred from something the tax authority can see — the passenger capacity of a minibus, the tonnage of a goods vehicle, the number of operating chairs in a salon, the stall in a designated market, the value of goods a cross-border trader imports. The charge is a fixed, periodic amount (usually quarterly), levied without any deduction of expenses and, for genuine informal operators, operating as a final tax — pay it and the income-tax obligation on that trade is discharged.
The regime is built from three pieces working together: the charging section, s36C of the Income Tax Act; the Twenty-Sixth Schedule, which defines the categories, the basis of charge, the compliance rules and the collection-through-agents machinery; and Section 22C of the Finance Act [Chapter 23:04], which sets the amounts and is revised in almost every national budget. A defining Zimbabwean feature is collection by intermediaries — landlords of designated premises, licensing bodies and mineral buyers are appointed to collect and remit on ZIMRA's behalf, and are personally liable if they fail.
This lesson explains who is caught, how each category is charged and collected, how presumptive tax interacts with ordinary assessment, VAT registration and the other levies, the point at which a growing operator "graduates" out of the regime, and the traps that catch both operators and the agents who collect from them. Because the schedule amounts change with each budget, the lesson teaches the durable framework in full and flags every specific figure for confirmation against the current Finance Act and any operative Statutory Instrument.
