Capital gains tax: preserve the story behind an asset disposal

Establish what happened and who owned the asset

Start with the asset, the legal owner and the transaction. Identify whether the event was a sale, donation, exchange, loss, transfer or another event requiring review. A cash receipt is not the only situation that can need capital-gains analysis, and a family or related-party transaction should not be assumed to fall outside the rules.

Build a timeline of acquisition, ownership changes, use and disposal. For jointly owned assets, identify the respective interests rather than splitting the final proceeds by a convenient percentage. Keep contracts, title or investment records and relevant correspondence together. The distinction between capital and revenue treatment also needs consideration; an asset's label in a spreadsheet does not decide it. SARS's capital-gains material provides the framework, while the actual facts determine how it applies. If ownership, intention, residency or the legal effect of a transaction is uncertain, identify the issue before beginning a calculation that assumes the answer.

Find the legally relevant disposal date

The date money reaches the bank may differ from the date relevant to the tax analysis. Agreements can include conditions, amendments or stages, and the legal timing needs to be assessed from the documents. Do not automatically use a property-transfer date, a settlement date or the day the accountant received the information as the disposal date.

Give your adviser the complete signed agreement and any conditions or changes, together with dates on which relevant events occurred. Explain whether an arrangement was cancelled, varied or completed in a different form. The year of assessment matters because rules, exclusions and other income can differ between years. A transaction spanning a year-end therefore deserves attention early, not after a return for one of the periods has been filed. Keep a short timing memorandum in the asset file so that future reviewers can understand why the disposal was reported in a particular year. This is especially important where the commercial timeline is more complicated than a simple cash sale.

Understand base cost without turning every expense into it

The relevant base cost is not necessarily just the purchase price, but neither is it every amount spent while owning the asset. SARS's base-cost guidance identifies the framework for qualifying acquisition, improvement and disposal costs and explains why amounts deducted against income cannot simply be counted again. The precise treatment depends on the facts and applicable rules.

Prepare an asset-cost schedule with dates, descriptions, amounts and supporting documents. Separate acquisition, improvements, repairs, financing and ordinary running costs for review instead of deciding from the bank narration alone. Where one price covered several assets, preserve the allocation and the evidence supporting it. For older assets or transactions involving deemed values, additional valuation-date or market-value analysis may be needed. Record uncertainty honestly; replacing a lost invoice with a guessed cost can create a misleading calculation. The objective is a supported history that lets the adviser identify qualifying amounts, not a folder arranged to maximise a preferred base-cost figure.

Reconcile proceeds to the transaction documents

Sale proceeds, cash received and accounting profit can differ. A disposal may involve selling costs, amounts settled directly, non-cash consideration or adjustments under the agreement. Prepare a reconciliation showing how the contractual terms connect to the amounts in the bank and ledger. Ask your adviser which amounts form the relevant proceeds for tax purposes.

Do not automatically subtract an outstanding loan from the sale price and call the balance the capital gain. Repaying finance and determining the tax result answer different questions. Similarly, a broker's cash statement may be useful evidence but may not explain all acquisition history or tax adjustments. Keep original transaction confirmations and a separate calculation rather than overwriting the provider's documents. Where consideration depends on future events or involves a connected person, obtain advice on the specific rules. A clear proceeds schedule helps prevent a common misunderstanding: the amount left in the bank after settling debts is not necessarily the amount on which the capital-gains calculation is based.

Check exclusions and inclusion rules for the actual taxpayer and year

Different taxpayers and assets can receive different treatment. Exclusions, limitations and inclusion rules should be checked against the relevant year, not copied from an old calculator. A primary-residence label, personal use or small-business description is not a substitute for examining the conditions and the asset's actual history.

The current SARS capital-gains rate and exclusion page should be read with the applicable legislation and effective dates. This guide intentionally does not reproduce changing monetary exclusions as though they apply to every disposal. Ask which rule is relied on, why its conditions are met and whether apportionment or another limitation is needed. A maximum effective rate is not a universal flat charge on proceeds or even on every taxpayer's gain. Capital losses also have their own treatment and should not be assumed to offset ordinary income. Keep the analysis with the calculation so the return reflects an explained position rather than a favourable number selected from a table.

A practical example: a property with changing use

Imagine a hypothetical individual who bought a property, lived in it, later let part of it and eventually sold it. The adviser needs the acquisition documents, improvement records, disposal agreement, ownership details and a timeline of use. A statement that “it was my home” does not by itself resolve every period or part of the property for tax purposes.

The preparation schedule distinguishes improvements from repairs for review, reconciles the contract price to settlement figures and identifies when the use changed. It also records any shared ownership and asks which costs have already been dealt with elsewhere. The adviser then assesses the relevant classification, timing and relief conditions. This example does not calculate an exclusion or imply that letting always removes or always preserves a particular benefit. Its lesson is that an accurate asset history makes a legal analysis possible. Keeping documents as expenditure occurs is usually far more reliable than trying to reconstruct years of activity from a few surviving bank statements at the time of sale.

Connect the disposal to the wider tax position

A disposal can affect more than the annual capital-gains schedule. Consider whether provisional-tax estimates, other taxes, accounting records or related-party balances require attention. The same transaction may need to be reported in several places for different purposes, and the figures should be connected by a clear explanation rather than assumed to be identical.

Tell your accountant about a proposed disposal before the return-preparation deadline. Provide a realistic transaction timeline and any expected changes in price or terms. If a transaction is abandoned or altered, preserve the history rather than deleting the original entry without a note. Keep the final tax calculation, supporting assumptions and evidence with the asset records. This helps when SARS asks a question or when another transaction depends on the remaining base cost or losses. A completed sale is a poor time to discover that nobody retained the purchase agreement, and a filed return is a poor time to learn that the agreement had a condition changing the relevant timing.

Preserve opening records when advisers or platforms change

When an investment platform, accounting package or adviser changes, obtain the history needed to support future disposals. A transferred opening value may be a market value for one purpose and not the tax base cost. Keep transaction-level records and ask what the supplied figures represent. If an asset was acquired through an inheritance, donation or restructuring, preserve the relevant documents and prior calculations rather than assuming the recipient starts with the original purchase price or the latest valuation. Establishing the correct starting point early can prevent a difficult reconstruction years later when the asset is sold.

Build an asset file while information is still available

For each significant asset, maintain an accessible file containing acquisition information, ownership changes, qualifying-cost evidence, use history and disposal records when applicable. Keep source documents separate from working calculations, and identify the tax treatment of any previous disposal or adjustment. Avoid relying on a software opening balance without knowing how it was established.

At your next review, ask which missing documents could materially affect a future calculation and prioritise obtaining them. For business assets, coordinate the capital-gains review with allowances and possible recoupments; those issues should not be collapsed into a single unexplained figure. Axia Finance can help organise the records and prepare capital-gains calculations from the relevant facts. This article is general educational guidance and does not determine whether a transaction is capital, the date of disposal or eligibility for an exclusion. Complex assets, foreign connections and related-party arrangements may need specialist advice before the transaction is finalised.
