Lesson 10 Teaching Pack

Capital Gains Withholding Tax Mechanisms
Zimbabwe-focused with UK and South Africa comparative notes. en-US. Date: 2026-03-16.

Executive summary

Capital gains withholding tax is Zimbabwe’s front-end collection mechanism for CGT on “specified assets” (especially immovable property and marketable securities). It is designed to prevent collection leakage by shifting the cash-collection point to intermediaries—notably depositaries (including conveyancers, legal practitioners, estate agents, financial institutions, stockbrokers, certain registrars, the Sheriff/Master, etc.), and in fallback scenarios, agents and ultimately the payee (seller). The mechanism is statutory in Part IIIA of the Capital Gains Tax Act [Chapter 23:01] and is reinforced by the Act’s clearance certificate regime and the registrar gating rule that can block registration of transfers where withholding was not applied. (zimra.co.zw)

In practice, the system runs as a tight timeline: when a depositary pays sale proceeds to the seller (or credits the seller), the depositary must withhold and remit by the 3rd working day (unless extended for good cause). Failure triggers (i) liability for the tax that should have been withheld and (ii) an additional 15% uplift penalty, which ZIMRA can waive if there was no intention to evade. The withheld amount is credited against the seller’s final CGT for that gain; excess is refundable subject to a six-year claim period, with statutory interest payable if ZIMRA delays beyond 60 days (subject to statutory exceptions). (zimra.co.zw)

This lesson trains learners to:
- identify the correct withholding actor (depositary → agent → payee) and trigger events;
- draft core practice documents;
- integrate clearance certificates into conveyancing and share-transfer workflows;
- manage reconciliation and credits/refunds; and
- anticipate dispute/enforcement risk (including the Sabeta case principle that ZIMRA, as a creature of statute, must perform statutory duties and should not add extra-statutory conditions). (lawportalzim.co.zw)

Learning objectives and recommended pre-reading

Learning objectives

By the end of Lesson 10, participants should be able to:

Explain what CGT withholding tax is (and is not): a collection mechanism distinct from final CGT, with its own liability chain and timelines. (zimra.co.zw)

Identify and apply the statutory responsibilities of depositaries, agents, and payees, including depositary registration obligations and severally liability rules where multiple depositaries hold proceeds. (zimra.co.zw)

Operationalize withholding in (i) property conveyancing and (ii) share transfers, using clearance certificates and registrar gating rules to prevent transfer delays. (zimra.co.zw)

Apply remittance timing (3rd working day), understand penalties and waiver potential, and manage documentation needed to support credits/refunds. (zimra.co.zw)

Draft and review core templates: withholding notice, clearance request, remittance instructions, and payee credit certificate. (zimra.co.zw)

Recommended pre-reading

Assign these before class (30–45 minutes total):
- Capital Gains Tax Act [Chapter 23:01] (updated to 1 Dec 2024): focus on Part IIIA withholding provisions (depositary, agent, payee, certificates, penalties, refunds) and section 30A registration gating rules. (zimra.co.zw)
- ZIMRA’s public Capital Gains Tax guidance: definition of specified assets; clearance-document pack; valuation posture; rates overview. (zimra.co.zw)
- Optional case-law anchor: Sabeta v Commissioner General, ZIMRA ZWHHC 79 (administration limits/mandamus). (lawportalzim.co.zw)

Detailed lesson script and lecture notes

Conceptual framing: meaning of CGT withholding tax

Instructor script (opening 5 minutes):
“CGT withholding tax is not primarily about the final tax rate. It is about collection at source. Zimbabwe uses withholding because the seller may disappear, be cash-constrained, or underreport. Withholding pushes compliance to the moment money changes hands—and assigns duties to actors who are easy to locate: conveyancers, estate agents, banks, stockbrokers, registrars.”

Core definition (teach precisely):
Under Part IIIA of the Capital Gains Tax Act, capital gains withholding tax is a tax that must be withheld and remitted by specified parties at specified moments in transactions involving a specified asset, functioning as an advance collection against the final CGT charge. The Act explicitly provides that withholding tax paid is credited against the CGT payable on the same capital gain; excess is refundable. (zimra.co.zw)

Teaching distinctions:
- Withholding tax is triggered by payment/crediting of proceeds (or representative receipt), not by the end-of-year return. (zimra.co.zw)
- Final CGT liability is determined by assessment rules and computation of capital gain, with withheld amounts as credits. (zimra.co.zw)

Agents responsible for withholding: depositaries, agents, payees

Teach this as a three-tier liability chain with clear “trigger moments.”

Depositaries: who they are (statutory definition)

The CGT Act defines “depositary” broadly and deliberately includes many intermediaries who hold or control the flow of purchase money. It includes (non-exhaustively):
- a conveyancer/legal practitioner/estate agent/other person who holds purchase price and pays it to seller on completion;
- building societies and other specified financial institutions;
- the Sheriff or Master;
- stockbrokers and other specified institutions;
- certain registrars for transfers/registrations of rights (and other listed roles in the statute). (zimra.co.zw)

Instructor tip: Put the statutory definition on a slide and underline “holds money and pays to the seller.” The system is designed around control of funds.

Depositary registration duties

A person acting as a depositary “in the ordinary course of business” must apply to the Commissioner for a registration certificate within 30 days after commencing the business (or transitional period requirements for existing operations). (zimra.co.zw)

Teaching point: depositary compliance is an institutional obligation; it is not optional “client service.”

Trigger for depositary withholding

When the depositary pays any amount held as depositary to or for the credit of the seller as a consequence of sale/transfer of a specified asset, the depositary must withhold withholding tax and remit it to ZIMRA no later than the 3rd working day from the date payment was made, unless extended for good cause. (zimra.co.zw)

Agents: the fallback withholding node

If withholding was not made by the depositary and no clearance certificate exists, any agent receiving funds on behalf of the payee must withhold and remit by the 3rd working day (same deadline structure). (zimra.co.zw)

Payees: ultimate fallback liability

If neither depositary nor agent withholds and no clearance certificate exists, the payee (seller) must pay to ZIMRA the amount that should have been withheld, by the 3rd working day from the date they received the payment. (zimra.co.zw)

Withholding on property transactions

This part is the “highest frequency” practice scenario.

Statutory triggers and the conveyancing “depositary moment”

In a property sale, the key statutory trigger is when the conveyancer/estate agent (as depositary) releases or credits funds to the seller. This is why ZIMRA’s clearance process requires buyer and seller interviews and a detailed document pack, and why valuation evidence matters (risk of undervaluation is explicitly addressed in ZIMRA guidance). (zimra.co.zw)

Clearance certificates in property transactions

A depositary need not withhold if, before paying the seller, the depositary or seller applies for and obtains a clearance certificate, and the Commissioner is satisfied that either (i) no CGT is likely payable, or (ii) CGT likely payable is less than the withholding amount and adequate arrangements exist for payment. The certificate can be issued subject to conditions (including return requirements). (zimra.co.zw)

Registrar gating (hard stop for transfer registration)

Where CGT is not withheld in terms of Part IIIA, registration of acquisition of a specified asset in the Deeds Registry must not proceed unless a certificate from ZIMRA states that any CGT payable has been paid. This is a critical administrative design feature that ties tax compliance to property rights transfer. (zimra.co.zw)

Sample property withholding workflow (teach as steps)

Use this as a “scripted walkthrough” in class:
1. Contract signed → conveyancer instructed → identify whether conveyancer is acting as depositary under the CGT Act definition. (zimra.co.zw)
2. Gather ZIMRA clearance file pack (CGT1, REV1, agreement of sale, title deed, IDs, proof of payment, etc.). (zimra.co.zw)
3. Decide: (A) withhold and remit; or (B) apply for clearance certificate (no/reduced withholding). (zimra.co.zw)
4. Settlement: release seller funds; if withholding route, remit by 3rd working day and issue withholding certificate. (zimra.co.zw)
5. Obtain the ZIMRA certificate required for registration where applicable; lodge transfer with Registrar. (zimra.co.zw)

Case-law cautionary note: If ZIMRA refuses to assess/issue certificates by importing extra conditions, Sabeta supports compulsory relief. However, practitioners should distinguish refusal to perform duty from legitimate requests for information needed to assess tax correctly. (lawportalzim.co.zw)

Withholding on share transfers

This section focuses on “marketable securities” and capital-market-adjacent compliance.

Share registrars and “registrar gating” for shares

The CGT Act’s registrar gating rules for specified assets also address shares: where CGT is not withheld, a certificate from the Commissioner must be submitted before the registrar responsible for transfer of shares registers the acquisition (or equivalent). (zimra.co.zw)

Brokers, nominees, and beneficial ownership

Zimbabwe’s statute defines depositaries to capture stockbrokers and others who may hold and pay proceeds; in addition, practical shareholding often involves nominee structures. The core compliance control is: identify the payee and the depositary controlling payment flows. (zimra.co.zw)

Teaching note: Zimbabwe’s CGT withholding design is “funds-flow-based,” not “registry-form-based.” Therefore, nominee holdings do not remove withholding obligations if the depositary pays proceeds.

Non-resident sellers and cross-border friction

Zimbabwe’s CGT Act treats “gross capital amount” as arising from a source within Zimbabwe, which is relevant to non-resident disposals; withholding becomes especially important where collection from a non-resident is hard. Use this as a discussion point even where the statute does not create a separate non-resident withholding rate in Part IIIA. (zimra.co.zw)

Scrip/IPO issues

Explain to students:
- “Scrip” transactions and IPO lock-ups can create disposal timing and valuation issues, but withholding usually triggers only when proceeds are paid/credited under the statutory mechanisms.
- When share transfers are part of reorganizations or non-cash consideration, clearance certificates and documentation become critical to avoid transfer delays and disputes about whether withholding should have occurred. Ground this in the Act’s clearance certificate power and its conditions. (zimra.co.zw)

Deposit and remittance obligations

Teach this section like a compliance training: “what must be done, by when, and what happens if not.”

Who remits and by when

• Depositary: remits withholding tax by the 3rd working day after paying/crediting the seller. (zimra.co.zw)
• Agent: remits by the 3rd working day after receiving funds on behalf of seller in the fallback scenario. (zimra.co.zw)
• Payee: remits by the 3rd working day after receiving payment where neither depositary nor agent withheld and no clearance certificate exists. (zimra.co.zw)

Payment methods and documentary discipline

ZIMRA’s public CGT guidance emphasizes proof of payment and transaction documents as part of clearance and compliance. In practice, teach students to ensure:
- payment reference numbers are captured;
- proof of payment is attached to the file;
- withholding certificates are issued and preserved for credits and refunds. (zimra.co.zw)

Penalties for late/non-remittance and mitigation

If a depositary or agent fails to withhold/pay:
- They are liable for the withholding amount that should have been withheld, plus
- an additional amount equal to 15% of that withholding amount.
The 15% may be waived or reduced if the Commissioner is satisfied there was no intent to evade. (zimra.co.zw)

Instructor caution: Students should not treat waiver as automatic; it is discretionary and fact-driven.

Credits for withholding tax and refund claims

Crediting mechanism

The Act provides that withholding tax paid is credited against CGT payable for the same gain, and any excess is refundable. This means withheld amounts must be tracked per transaction and tied to the seller’s final CGT computation. (zimra.co.zw)

Refund claims and time limits

Where withholding tax paid exceeds final CGT:
- The seller (or controlling party) may claim a refund within six years after payment.
- Interest is payable if ZIMRA does not refund within 60 days after claim or after assessment completion (whichever is later), unless delay is due to the taxpayer’s defective return or error. (zimra.co.zw)

Documentation required for credits and refunds

Teach “evidence triad”:
- withholding certificate issued by depositary/agent;
- proof of payment to ZIMRA;
- transaction documents showing asset identity and parties. (ZIMRA clearance pack provides a practical blueprint of required docs.) (zimra.co.zw)

Comparative notes (brief)

• UK: For certain property disposals, HMRC requires reporting and payment within tight deadlines (commonly 60 days from completion for UK residential property disposals), illustrating a “post-completion rapid payment” approach rather than depositary withholding by conveyancers in most domestic cases. (gov.uk)
• South Africa: Non-resident immovable property sales are governed by a purchaser withholding regime (s35A) with directives to reduce/no withholding—an alternative design where the purchaser is central. SARS provides an external guide explaining the directive and withholding mechanics. (sars.gov.za)

Case study with model answer

Scenario:
A buyer purchases a residential property. The conveyancer holds the full purchase price in trust and is closing on Friday. The seller insists that the conveyancer release the full amount immediately and says they will “sort out CGT later.” No clearance certificate has been obtained. The agreed sale price appears below market; the seller proposes signing a “side letter” showing the true higher price while keeping a lower price on the agreement of sale to reduce taxes.

Questions:
a) What are the conveyancer’s withholding obligations and deadlines?
b) What are the legal and practical risks of the “side letter” structure?
c) What documentation and steps should be taken to ensure the seller receives credit for withholding tax against final CGT?

Model answer:
a) The conveyancer qualifies as a depositary (statutory definition includes conveyancer/legal practitioner holding and paying purchase price). When paying/crediting the seller, the conveyancer must withhold withholding tax and remit to ZIMRA no later than the 3rd working day after payment unless a clearance certificate is obtained before payment. Therefore, release of the full amount without withholding or clearance is non-compliant. (zimra.co.zw)
b) A side letter intended to misstate consideration for tax purposes risks illegality and can undermine enforceability; Zimbabwe courts have treated tax/duty evasion structuring harshly in property disputes, sometimes invoking stamp duty anti-evasion rules and refusing enforcement. Beyond private-law risk, ZIMRA may require valuation evidence and can uplift valuations where declared values are outside market value. (zimra.co.zw)
c) The conveyancer should (i) remit withheld amount by the deadline, (ii) issue a withholding certificate to the seller with required particulars, (iii) keep proof of payment and supporting transaction documents, and (iv) ensure the seller’s final CGT assessment claims the credit; if excess withholding exists, a refund claim can be made within six years, with possible interest if delayed beyond 60 days. (zimra.co.zw)

Short practical checklist for practitioners (Zimbabwe)

Use this as a “desk card”:

• Confirm if the asset is a “specified asset” (immovable property/marketable securities). (zimra.co.zw)
• Identify the withholding node: depositary? agent? direct-to-seller?
• If depositary will pay seller: diarize 3rd working day remittance deadline. (zimra.co.zw)
• Decide early: withhold vs clearance certificate.
• If clearance certificate: file before releasing funds; prepare full ZIMRA document pack. (zimra.co.zw)
• Issue withholding certificate and store proof of payment; ensure seller can claim credit/refund. (zimra.co.zw)
• Avoid side letters/false consideration; valuation risk and illegality risk are high. (zimra.co.zw)

Classroom activities

• Workflow roleplay (25–30 min): teams act as seller, buyer, conveyancer (depositary), and ZIMRA officer. They must choose withholding vs clearance and produce a settlement statement with the remittance deadline. Use ZIMRA’s required document pack as the evidence checklist. (zimra.co.zw)
• Document drafting lab (20 min): learners complete the four templates (withholding notice, clearance request, remittance instruction, credit certificate) from a fact pattern.
• Compliance debate (10 min): “Does registrar gating reduce avoidance more efficiently than purchaser withholding?” Use South Africa s35A guidance (purchaser withholding) as the comparator design. (sars.gov.za)

One-page quick reference summary (end)

Core concept: CGT withholding tax is collection at source for specified asset disposals; it is credited against final CGT. (zimra.co.zw)

Who withholds/pays (chain):
1) Depositary (primary) → withhold when paying/crediting seller; remit by 3rd working day; issue certificate.
2) Agent (fallback) → same timeline.
3) Payee (seller) (last resort) → pay what should have been withheld by 3rd working day. (zimra.co.zw)

Clearance certificate: allows reduced/no withholding before paying seller if Commissioner satisfied; certificate may have conditions. (zimra.co.zw)

Registrar gating: where not withheld, registration (Deeds/shares) generally cannot proceed without ZIMRA certificate that CGT payable has been paid. (zimra.co.zw)

Penalties: depositary/agent failures → liability for tax + 15% additional amount; waiver possible if no intent to evade. (zimra.co.zw)

Credits and refunds: withholding credited against final CGT; excess refundable if claimed within 6 years; interest may apply if refund delayed beyond 60 days (subject to exceptions). (zimra.co.zw)

Practice mantra: If you control proceeds, you control withholding risk.
