The administration of capital gains tax (CGT) is the machinery through which the Zimbabwe Revenue Authority (ZIMRA) turns the substantive CGT charge into collected revenue: how a seller is registered, how a disposal is declared on the Form CGT 1, how the tax is paid, how transfers are gated until the tax is settled, how third parties report disposals, and how the whole system is enforced. This lesson assembles those moving parts into a single operating picture. The governing law is the Capital Gains Tax Act [Chapter 23:01], which — rather than re-write a complete administrative code — imports the Income Tax Act (Taxes Act) [Chapter 23:06] machinery mutatis mutandis through Sections 23, 24, 27, 28 and 29, and adds CGT-specific provisions in Section 26 (payment), Sections 30A and 32 (transfer-gating) and Section 31 (third-party returns), all sitting on top of the Part IIIA withholding administration (Sections 22FA registration and 22G returns).
The declaration instrument is the Form CGT 1 — Return for Remittance of Capital Gains Tax, filed on the ZIMRA Self-Service Portal (SSP) for two asset classes only: immovable property in Zimbabwe and marketable securities. It is filed per disposal by the seller (or, in practice, by the conveyancer/estate agent acting as depositary), with prescribed supporting documents attached. A disposal that is wholly exempt under Section 10 needs no CGT 1; listed-share disposals are covered by the 1% final withholding (see Capital Gains Withholding Tax) and do not normally require a CGT 1.
The payment rule is in Section 26 of the CGT Act: tax is due no later than 30 days from the relevant accrual/transfer date (or the earlier Part IIIA withholding date). The ZIMRA CGT 1 guide refers to this 30-day rule as "Section 13", but Section 13 of the CGT Act actually deals with damage/destruction — so the operative payment provision is Section 26, and the guide's "Section 13" citation should be treated as a known mis-citation (consistent with CGT Returns and Assessments).
Registration runs on two tracks. Ordinary sellers may have no TIN until the SSP issues one as part of the CGT registration on first disposal. Separately, every person who acts as a depositary in the ordinary course of business (conveyancers, estate agents, stockbrokers, financial institutions) must register within 30 days under Section 22FA — failure being a criminal offence — and file monthly returns with the tax under Section 22G.
The keystone of CGT administration is the transfer gate. Under Sections 30A and 32, neither the Registrar of Deeds nor a company's share-transfer official may register the acquisition of a specified asset unless a ZIMRA certificate confirming the CGT has been paid is produced. No certificate, no transfer — which makes payment effectively unavoidable. The complement, from Sabeta M v Commissioner-General, ZIMRA (12-HH-079), is that ZIMRA must issue that certificate once the tax is paid. Reinforcing the gate, Section 31 requires the Registrar of Deeds (and, when not suspended, banks, building societies and brokers) to report transfers to ZIMRA — giving the Authority an independent cross-check.
Enforcement is imported: Section 27 brings in the Taxes Act offences (Sections 81–86), evidence (Sections 87–88), forms/service (Section 89) and regulations (Section 90); Section 28 imports double-tax relief (Taxes Act Section 91); and Section 29 imports the general anti-avoidance rule (Taxes Act Section 98). Penalties and interest for late or false returns flow through this imported machinery (the ZIMRA guide additionally references its own penalty sections — flagged below for verification). This lesson builds on CGT Returns and Assessments (the Section 23 assessment detail), Role of Intermediaries and Depositaries and Capital Gains Withholding Tax (the withholding/collection layer), Payment of CGT and Clearance Certificates (due dates and recovery), How to Object and Appeal a CGT Assessment (disputes), and Provisional Tax, QPDs and PAYE Administration (the parent income-tax administrative architecture it borrows).
