CGT Returns and Assessments in Zimbabwe

Executive summary

Report date: 16 Mar 2026 (Africa/Harare).

Capital Gains Tax (CGT) administration in Zimbabwe is a hybrid of (i) transaction-by-transaction “return-and-remit” compliance (commonly through Form CGT1 and the CGT Clearance Certificate workflow needed for registrable transfers) and (ii) a formal assessment framework imported (mutatis mutandis) from the Income Tax Act [Chapter 23:06] (“Taxes Act”) into the Capital Gains Tax Act [Chapter 23:01] via section 23.

For advanced practice, the key legal insight is that CGT “returns” are not only taxpayer declarations: the Act contemplates a broader information ecosystem (Registrar of Deeds and certain financial intermediaries must notify ZIMRA at intervals the Commissioner requires).

Timing is heavily event-driven. As a baseline, CGT becomes due within 30 days either from (a) the date an amount is deemed to have accrued under special timing rules (notably suspensive-condition sales under s 18 and credit/instalment sales under s 19) or (b) otherwise, from the date title is formally transferred. This interacts with “year of assessment” rules because allowances that defer part of the taxable amount (especially under s 18 and s 19) are pulled into the following year’s return.

Assessments may arise because the Commissioner is empowered—through incorporated Taxes Act provisions—to raise estimated assessments where a taxpayer defaults or information is unsatisfactory, issue additional assessments (subject to key time limits and exceptions), and make reduced assessments/refunds when over-taxation is proved.

Electronically, ZIMRA’s move to TaRMS is not merely operational: Taxes Act “information technology” provisions authorize computerized receipt/processing of returns and related documents, and ZIMRA has publicly stated that submission of tax returns and refund claims is only via TaRMS; for CGT specifically, ZIMRA confirmed manual CGT clearance certificates are discontinued and TaRMS-generated certificates are verifiable online.

Learning objectives and scope

By the end of this chapter, students and practitioners should be able to:

Interpret the statutory architecture that governs CGT returns and assessments: the Capital Gains Tax Act as the charging statute, the Finance Act for rates, and the Taxes Act provisions that are incorporated for returns/assessments and information technology.

Design compliant workflows for transactional CGT filing, including documenting the transaction, preparing CGT1, managing TaRMS interactions, and securing CGT clearance where registration depends on proof of payment.

Apply the statutory timing rules for ordinary disposals (30-day rule tied to transfer) versus special rules: suspensive-condition sales (s 18) and credit/instalment sales (s 19), including how deferral allowances are computed and carried into the next year.

Analyse assessment outcomes: when ZIMRA may issue estimated/additional assessments, how a taxpayer can correct errors (reduced assessments/refunds), and how objection time limits integrate into CGT compliance risk management.

Scope note: This chapter focuses on returns, assessments, and related procedural rules (including timing and TaRMS). It does not attempt a full re-teaching of capital gain computation rules beyond what is necessary for filing/assessment examples.

Statutory and administrative framework for CGT returns and assessments

Core statutes and how they interlock

The Capital Gains Tax Act [Chapter 23:01] provides the charge to CGT and is the primary statute governing CGT administration (including clearances, third-party notifications, and objection rights).

Rates are fixed through the Finance Act [Chapter 23:04]. For example, as consolidated on ZIMRA’s legislation portal (updated to 1 Dec 2024), section 38 sets CGT rates by reference to acquisition timing (pre-/post-22 Feb 2019), and section 39 sets withholding tax rates for Part IIIA mechanisms.

The Revenue Authority Act [Chapter 23:11] establishes ZIMRA and frames its role as the State’s agent in “assessing, collecting and enforcing” revenues. This anchors ZIMRA’s administrative posture within the CGT system.

Most importantly for “Lesson 12,” CGT Act s 23 imports (“shall apply, mutatis mutandis”) a package of Taxes Act (Income Tax Act) provisions covering (among other items) notices calling for returns, further information powers, estimated and additional assessments, refunds, and the information technology chapter.

What counts as a “CGT return” in Zimbabwe

At an advanced level, “CGT return” should be understood as a bundle of compliance instruments, not one artifact:

Transactional remittance return: ZIMRA’s Form CGT1 (Return for Remittance of Capital Gains Tax) is structured to capture seller identity and transaction data for immovable property and for unlisted marketable securities, and it includes a tick-list of common attachments (title deeds, agreements, proof of purchase price, IDs, executor documents where relevant).

Third-party information returns: the CGT Act requires (i) the Registrar of Deeds to notify the Commissioner of all property transfers (names/addresses and price) at intervals the Commissioner requires, and (ii) specified financial institutions/brokers to notify ZIMRA about certain marketable security sales (though this notification regime may be suspended until activated by Gazette notice).

Depositary/intermediary returns (Part IIIA): while Lesson 11 addresses intermediaries in depth, Lesson 12 must note that Part IIIA includes a depositary-return regime; and the Act also provides for suspension of Part IIIA features regarding marketable securities (including depositary returns to the extent depositaries hold monies representing the price).

TaRMS as the electronic compliance environment

Two levels matter: statutory permission and administrative implementation.

On the statutory side, Taxes Act Part VIIIA authorizes the Commissioner to establish computer systems for “despatch and receipt and processing” of returns, assessments, declarations, forms, and other tax documents; and it provides for a “Virtual Tax Management System” platform whose operating rules must be prescribed by regulation.

On the administrative side, ZIMRA publicly stated that submission of tax returns and refund claims will only be done through TaRMS via the Self-Service Portal, a strong operational signal on how filing/claims are expected to occur. For CGT specifically, ZIMRA issued Public Notice 56 of 2024 confirming: (i) validation of TaRMS-generated CGT clearance certificates, (ii) discontinuation of manual CGT clearance certificates, and (iii) taxpayer access to CGT clearance certificates through the TaRMS Self Service Portal.

Submission of CGT returns and timing rules

Who must file or remit, and through whom

ZIMRA’s CGT guidance states that the seller is liable to pay/remit CGT, but that a depositary (including conveyancers, legal practitioners, estate agents, building societies, Sheriffs/Master of the High Court, stockbrokers/financial institutions) may remit in practice; and it notes expansion of the “depository” concept to include certain registrars/registering officials for specified rights/title registers (from 1 Jan 2017).

Statutorily, if CGT is not withheld under Part IIIA, registration of acquisition of the specified asset (deeds or share transfers) cannot proceed unless a ZIMRA certificate confirming CGT payment is submitted to the Registrar of Deeds or the responsible shares transfer official.

Forms and required attachments

Primary return form used in practice

Form CGT1 is the principal ZIMRA domestic taxes form designed as a “Return for Remittance of Capital Gains Tax.” It requests (among other elements) seller identity/tax identifiers, asset details, sale and cost information, and flags for special treatments including rollovers, suspensive sale conditions, and certain exemptions/reliefs.

Typical attachments

The CGT1 form itself includes a “CGT attachments” checklist commonly including: copy of title deeds, purchase and sale agreement, identification, proof of purchase price, and for deceased estates, death certificate and letters of appointment.

ZIMRA’s CGT guidance page adds contextual documentation expectations for clearance processing (e.g., agreement of sale, deed/share certificate, proof of payment, IDs, utility bills where claiming rollover/exemption, powers of attorney for absent parties, and valuation reports in certain cases or at ZIMRA request).

Filing and timing mechanics

Baseline statutory due-date rule

CGT becomes due and payable no later than 30 days:

• from the date when a specified asset “accrues” to a taxpayer under s 18(1) or s 19(1) (i.e., under suspensive-condition or credit/instalment timing rules), or
• otherwise, from the date title to the specified asset is formally transferred.

Special timing rules for instalments and suspensive-condition sales

Suspensive-condition sale (s 18): where an agreement provides that ownership passes upon/after receipt of the whole or a portion of the amount payable, the whole amount is deemed to have accrued on the agreement date.

The critical “returns-and-year-of-assessment” interface is the statutory allowance mechanism:

• The Commissioner deducts an allowance computed by:
  Allowance = A × (B − C) / D,
  with variables defined by the Act (A = portion not receivable at year-end; B = capital amount deemed accrued; C = certain deductible sums; D = amount deemed accrued).
• The allowance deducted is then included by the taxpayer as a capital amount in the return for the following year of assessment.

Credit/instalment sale where ownership passes on delivery (s 19): similarly deems the whole amount to have accrued on the agreement date when the price is payable in instalments, but gives the Commissioner discretion to deduct an allowance “as seems reasonable” for amounts not receivable at year-end; that allowance is also included in the taxpayer’s capital amount in the following year’s return.

TaRMS procedural overlay and clearance certificates

For property and other registrable transfers, filing is functionally linked to the CGT Clearance Certificate workflow:

• ZIMRA states the clearance certificate is issued once amounts due have been paid and ZIMRA concludes/finalizes the transaction; the certificate facilitates property transfer to the new owner.
• ZIMRA’s Public Notice confirms taxpayers access CGT clearance certificates through their TaRMS Self Service Portal and that manual issuance has been discontinued.

  G --> H[TaRMS-generated CGT Clearance Certificate issued]
  H --> I[Present certificate to Registrar / transfer official]
  B -- No --> J[Pay CGT within statutory 30-day rule\nKeep records for audit/assessment]

This workflow is grounded in the certificate-linked registration requirement (where CGT is not withheld) and ZIMRA’s TaRMS-based CGT clearance certificate framework.

Worked example on timing and filing

Example A: Ordinary sale with transfer-based due date

Facts (assumptions for training):

• Asset: residential stand with title deeds (immovable property = specified asset).
• Seller acquired property after 22 Feb 2019 and is therefore taxed at $0.20 per $1 of capital gain (20%).
• Sale price: US$120,000.
• Acquisition cost: US$70,000.
• Improvements (allowable): US$10,000.
• Selling legal costs: US$2,000.
• Title transfers on 1 June 2026.

Computation (simplified to illustrate filing/assessment mechanics):

Capital gain = 120,000 − (70,000 + 10,000 + 2,000) = US$38,000
CGT = 20% × 38,000 = US$7,600

Deadline mechanics:

Because this is not framed as a s 18 or s 19 arrangement, due date follows the title-transfer rule: tax is due no later than 30 days from 1 June 2026 → 1 July 2026.

Practical filing package:

Prepare CGT1 and attach (at minimum) sale agreement, deed of transfer copy/original, IDs, proof of payment, and any other documents ZIMRA requests; submit via TaRMS workflow to obtain the clearance certificate needed for registration.

Assessments: self-calculation, ZIMRA assessments, estimated and amended assessments

Legal basis: assessments in CGT are largely “imported” machinery

CGT Act section 23 incorporates Taxes Act provisions on:

• calling for returns (s 37) and further information (s 39),
• accounts and supporting documentation (s 43),
• estimated assessments (s 45), additional tax for defaults/omissions (s 46), additional assessments (s 47), reduced assessments/refunds (s 48), amended loss assessments (s 49), and the assessment issuance rules (s 51–52),
• as well as the information technology chapter (Part VIIIA).

This means CGT “assessment law” is not invented anew; it is an adapted transplant of Income Tax Act machinery into the CGT environment.

Self-calculation versus formal assessment

The statutory picture

Unlike the Income Tax Act’s explicit self-assessment regime (s 37A), CGT Act s 23 does not list s 37A among provisions imported into CGT. Therefore, CGT does not rest on an express “self-assessment return = assessment” equivalence in the same way income tax does.

The functional (practice) picture

Operationally, the CGT system functions as taxpayer/depositary computation + payment + clearance: CGT1 is completed with the taxpayer’s figures and supporting evidence, and ZIMRA issues a clearance certificate once it is satisfied amounts due are paid and the transaction is finalized.

Where ZIMRA is not satisfied (e.g., valuation concerns), ZIMRA indicates it may invoke statutory powers (e.g., fair market value determination powers) and request valuations/interviews.

Comparison table: practical “self-calculation” vs ZIMRA assessment event

Estimated assessments

Statutory basis and when they are used

Through CGT Act s 23, Taxes Act s 45 applies to CGT: where a taxpayer defaults in furnishing returns/information, or where the Commissioner is not satisfied with what is furnished, the Commissioner may issue an assessment with taxable income/assessed loss estimated (and give notice); and where a person cannot furnish an accurate return, the Commissioner may agree an amount, which is not subject to objection/appeal (subject to later increase if information was withheld).

Procedural mechanics (step-by-step)

An advanced procedural view:

Identify default/deficiency: missing CGT1-like return/evidence, incomplete cost records, contradictory documents, non-cooperation, or urgency concerns.

Commissioner estimates tax base: for CGT this typically means estimating the capital amount, allowable deductions, and therefore gain (plus applying the correct rate under the Finance Act).

Issue notice of the estimated assessment: Taxes Act assessment notices must be given to the taxpayer.

Taxpayer response: the taxpayer can cure by furnishing the missing information; the legal position on objection rights will depend on whether the amount was agreed under s 45(2) (generally not objectable) versus estimated unilaterally under s 45(1) (generally subject to ordinary objection mechanisms, unless otherwise limited).

Worked example B: estimated assessment and later correction

Facts (training assumptions):

• Seller sells an unlisted company interest (marketable security) for US$300,000.
• Seller fails to provide acquisition cost evidence and does not submit complete information in response to ZIMRA requests.
• ZIMRA estimates: acquisition cost = US$0 (worst-case) and selling costs = US$0.
• Asset falls under post-22 Feb 2019 “20% of capital gain” regime for illustration.

Estimated assessment (ZIMRA position):

Estimated capital gain = 300,000 − 0 = 300,000
Estimated CGT = 20% × 300,000 = 60,000

Later correction:

Taxpayer later produces bank transfer records and share subscription documentation proving acquisition cost US$220,000 and transaction fees US$5,000.

Correct capital gain = 300,000 − (220,000 + 5,000) = 75,000
Correct CGT = 20% × 75,000 = 15,000

Procedural consequence:

The taxpayer’s pathway becomes a “reduce assessment/refund” argument—i.e., proving to the satisfaction of the Commissioner that tax was charged in excess—under Taxes Act s 48 as applied to CGT via CGT Act s 23, subject to time limits for claims.

Additional assessments and amended assessments

Additional assessments (upward adjustments)

Taxes Act s 47 (as applied by CGT Act s 23) empowers the Commissioner, after an assessment, to adjust where taxable income should have been charged but wasn’t, or credits were wrongly granted—subject to key protections and time limits (notably, a general “no adjustment after 6 years from the end of the relevant year of assessment,” unless fraud/misrepresentation/wilful non-disclosure).

In CGT practice, common s 47 triggers include: undisclosed side-consideration, related-party under-pricing, omission of recoupments, or failure to include a prior-year allowance add-back mandated by s 18 or s 19 in the following year’s return.

Reduced assessments and refunds (downward adjustments)

Taxes Act s 48 requires the Commissioner to issue an amended assessment reducing tax if it is proved the taxpayer was charged in excess, and to authorize a refund where tax was overpaid—subject to limitations (including a requirement that the refund claim be made within 6 years after the date of the notice of assessment in question).

From a systems perspective, ZIMRA’s TaRMS operational posture matters: ZIMRA has said that refund claims are submitted through TaRMS.

Objections and their place in the assessment lifecycle

A taxpayer aggrieved by an assessment under the CGT Act may object within 30 days of the notice of assessment (or written decision notification), per CGT Act s 25, and the CGT Act applies Taxes Act objection and appeal provisions (s 62–70) mutatis mutandis.

This flow reflects the statutory 30‑day objection window and the CGT Act’s adoption of Taxes Act objection/appeal rules.

Worked example C: suspensive sale allowance, return timing, and later inclusion

Purpose: show how CGT timing and returns bridge two years of assessment under s 18.

Facts (assumptions):

• 1 Oct 2025: Seller signs agreement to sell commercial property for US$200,000.
• Contract is suspensive: ownership passes only after buyer pays at least US$150,000.
• By 31 Dec 2025 (year-end assumption for teaching): buyer has paid US$120,000; remaining US$80,000 not receivable at year-end.
• Deductions allowed in s 18 formula (aggregate C) = US$120,000 (acquisition cost + improvements + transaction costs relevant to s 11(2)(a)–(d)).
• Therefore:
• B (capital amount deemed accrued) = 200,000
• A (portion not receivable at year-end) = 80,000
• C = 120,000
• D = 200,000 (amount deemed accrued under agreement).

Step 1: Accrual and deemed timing

Under s 18(1), the whole amount is deemed to have accrued on the agreement date (1 Oct 2025).
Due date is then governed by CGT Act s 26(1)(a): payable no later than 30 days from the accrual date under s 18.

Step 2: Compute s 18 allowance

Allowance = A × (B − C) / D
= 80,000 × (200,000 − 120,000) / 200,000
= 80,000 × 80,000 / 200,000
= 32,000

Interpretation: part of the gain is deferred to the next year by deducting this allowance now, then bringing it back next year.

Step 3: Current-year taxable capital gain (simplified)

Total “gross gain” = (B − C) = 80,000
Deferred via allowance = 32,000
Taxable gain in 2025 (simplified) = 80,000 − 32,000 = 48,000

CGT rate assumption (post-22 Feb 2019 asset): 20% of capital gain.
CGT payable for 2025 portion = 20% × 48,000 = 9,600

Step 4: Following-year inclusion (return mechanics)

Section 18(1)(ii) requires the allowance deducted (32,000) to be included by the taxpayer as a capital amount in the return for the following year of assessment.
Assuming no other adjustments, additional CGT in 2026 on that inclusion = 20% × 32,000 = 6,400.

Compliance note: this is a classic audit trigger—failure to include the allowance in the next year can drive an additional assessment risk under Taxes Act s 47 as applied to CGT.

Compliance checklist, documentation pack, and common pitfalls

High-control compliance checklist for CGT returns and assessments

This checklist aligns statutes (deadlines/assessment tools) to TaRMS operational expectations.

Confirm the correct timing rule: ordinary transfer-based due date vs s 18 (suspensive) or s 19 (credit sale).

Assemble the “defensible file” (minimum viable evidence): - CGT1 completed (as applicable) with accurate seller identifiers and transaction details.
- Title deed / share certificate / deed references and agreement of sale.
- Proof of purchase price/acquisition cost and proof of improvements/transaction costs.
- IDs (seller and buyer) and authorizations (power of attorney, executor documents for estates).

Use TaRMS correctly: - Ensure taxpayer access/registration and use the Self Service Portal consistent with ZIMRA’s statements on returns/refunds and CGT clearance certificate access.

Track year-of-assessment “carryover” inclusions: - For s 18 and s 19 allowances, schedule the following-year inclusion into the next year’s return position.

Monitor assessment notices and objection deadlines: - If an assessment issues, diarize the 30-day objection window (CGT Act s 25).

Refund discipline: - Where overpayment is established, understand the legal route (Taxes Act s 48 as incorporated) and ZIMRA’s operational requirement that refund claims are submitted via TaRMS.

Common pitfalls and audit triggers

Timing mismatches: paying based on transfer date when the transaction is actually a suspensive-condition agreement (s 18) or credit sale (s 19) can create late-payment exposure because accrual is deemed earlier.

Failure to carry allowances into the next year: the statutory mechanism explicitly pulls the allowance into the following year’s return; omission can support a later additional assessment.

Incomplete cost records: inability to prove acquisition cost or improvements invites estimated assessment risk (s 45) and/or adverse valuation adjustments.

Neglecting the clearance certificate dependency: where CGT is not withheld under Part IIIA, the Registrar/transfer official cannot register the transfer without a ZIMRA certificate proving CGT payment.

Late refund claims: reduced assessment/refund pathways are time-bar sensitive (s 48 includes a 6‑year claim limit in its provisos).

Selected authoritative interpretations and case law pointers

Because CGT assessment machinery is adopted from the Taxes Act, judicial interpretations of the Taxes Act assessment sections often matter by analogy in CGT disputes (via “mutatis mutandis” adoption).

Within CGT-specific materials, the consolidated CGT Act text itself points readers to certain CGT-related cases in editorial notes (e.g., on clearance/transfer dynamics and objections).
In practice, when teaching or advising, ensure you locate and read the full judgments from an authoritative law report database where available; use citations in the Act as leads rather than as substitutes for the ratio decidendi.
