When a taxpayer and ZIMRA disagree about a capital gains tax (CGT) assessment or a Commissioner's decision, the dispute is resolved through a structured, time-bound process of objection and then appeal. The gateway is Section 25 of the Capital Gains Tax Act [Chapter 23:01], which gives a taxpayer "aggrieved by any assessment made upon him" or by a defined list of the Commissioner's discretionary decisions the right to object within 30 days. Section 25 does not build its own machinery from scratch; instead it applies, mutatis mutandis, the objection-and-appeal provisions of the Income Tax Act [Chapter 23:06] — specifically subsections (2)–(6) of Section 62 and Sections 63 to 70 — so the CGT dispute pathway is, in substance, the income-tax pathway you met in Provisional Tax, QPDs and PAYE Administration, transposed onto capital gains.
The pathway has three tiers. Tier 1 — objection to the Commissioner. A taxpayer must lodge a written objection, specifying in detail the grounds, within 30 days of the notice of assessment or of the written notification of the decision (Section 25(1) of the CGT Act; Section 62(3) of the Taxes Act). The Commissioner may reduce, alter or disallow the assessment; if he does not notify his decision within 3 months, the objection is deemed to have been disallowed (proviso to Section 62(4)). If no objection is lodged, or an objection is disallowed or withdrawn, the assessment becomes final and conclusive (Section 62(5)).
Tier 2 — appeal to the High Court or the Special Court for Income Tax Appeals. A dissatisfied taxpayer may appeal, electing either the High Court or the Special Court (Section 65(1), read with the Twelfth Schedule), by lodging a written notice of appeal with the Commissioner within 21 days of the decision (Section 65(2)). The appeal is a full rehearing (PL Mines (Pvt) Ltd v ZIMRA 15-HH-466), but the appellant's arguments are limited to the grounds stated in the notice of objection (Section 65(4)) — there is no "ambushing" with fresh grounds. Hearings are held in private (Section 65(7)) and no order for costs is made unless the Commissioner's claim was unreasonable or the appeal frivolous (Section 65(12)).
Tier 3 — appeal to the Supreme Court. From the determination of the High Court or Special Court, either party may appeal to the Supreme Court on a question of law alone as of right, or on a question of fact, or of mixed law and fact, only with leave (Section 66). Subject to that, the lower court's decision is "final and without appeal" (Section 65(13)).
Two principles dominate the whole process. First, the burden of proof is on the taxpayer (Section 63): in any objection or appeal, the person claiming an exemption, non-liability or deduction must prove it, and the court will not reverse the Commissioner's decision unless the appellant shows it is wrong. This is the "double onus" you encountered in Capital vs Revenue Receipts. Second, objecting or appealing does not suspend the duty to pay (Section 69): the obligation to pay the tax "shall not, unless the Commissioner otherwise directs, be suspended pending a decision on any objection or appeal" — the pay-now-argue-later rule (Ellis N.O. v Commissioner of Taxes 92-SC-001). If the assessment is later altered, a due adjustment (refund or further recovery) is made.
What can be disputed is also defined. Beyond the assessment itself, Section 25(1)(b) lists the specific Commissioner decisions that may be objected to — among them the fair-market-price deeming under Section 8(2)(b) and (e), valuation and cost decisions under Section 11, the damage/destruction determination under Section 13(3), the fair market price determination under Section 14, the intra-group transfer decision under Section 15, and the principal private residence determinations under Section 21. By contrast, Section 68 confirms that, save for those listed decisions, no decision of the Commissioner is subject to objection or appeal. The leading CGT authority confirming that these income-tax procedures govern CGT disputes is Sommer Ranching (Pvt) Ltd v Commissioner of Taxes 99-SC-065. This lesson walks the entire pathway clause by clause, works a dated timeline, integrates the controlling case law, and flags the traps that cost taxpayers their right to be heard.
