South African company directors can now hold Bitcoin as a treasury asset with clear accounting and tax frameworks in place. The International Accounting Standards Board amended IAS 38 in 2024 to allow Bitcoin to be measured at fair value with gains recognised in profit or loss, and the JSE adopted that guidance. The decision is no longer legally ambiguous. For a director evaluating whether this is appropriate for their company, the practical questions are accounting treatment, SARS implications, board approval, custody structure and ongoing disclosure obligations.
This guide covers each of those in sequence.
| Decision area | What a director needs to know |
|---|---|
| Accounting classification | IAS 38 (intangible asset at fair value) is the standard choice. Gains and losses flow through profit and loss each reporting period. |
| SARS tax treatment | CGT applies when the company disposes of Bitcoin. Unrealised accounting gains are not taxed. Company CGT rate is 22.4% (80% inclusion at 28%). |
| Board authority | The board must pass a resolution before acquiring Bitcoin. The MOI must permit the investment. Listed companies need audit committee oversight. |
| Custody | Bitcoin must be held in the company’s name using segregated, multi-signature custody. A personal exchange account is not acceptable. |
| Listed company disclosure | Material Bitcoin positions must be disclosed in annual financials and via SENS. Auditors must verify the holding and confirm fair value measurement. |
| Record-keeping | Maintain both the accounting fair value and the SARS cost basis separately. They diverge whenever fair value moves and no disposal has occurred. |
The Accounting Treatment
Bitcoin held as a corporate treasury asset is classified under IAS 38 as an intangible asset, measured at fair value at each reporting date.
Gains or losses from changes in Bitcoin’s fair value flow through profit and loss, directly affecting the company’s reported earnings. Shareholders, lenders and analysts will see those movements in the income statement. A 40% rise in Bitcoin’s price during a financial year shows up as a gain. A 30% fall shows up as a loss.
An alternative classification exists under IFRS 9 as a financial instrument measured at fair value through other comprehensive income. Under that treatment, gains and losses appear in OCI rather than directly in profit and loss, depending on the company’s election at initial recognition. Most companies holding Bitcoin as a treasury reserve use IAS 38 because it is simpler and consistent with treating Bitcoin as a held asset rather than a trading instrument.
The initial purchase is capitalised at cost on the balance sheet. At each subsequent reporting date, the Bitcoin is revalued to current market price. The director needs to understand which classification the company has adopted, what the audit implication is, and how the resulting volatility will appear in financial statements that shareholders review.
SARS Tax Treatment
SARS taxes Bitcoin held by a company as a capital asset. The tax event is disposal, not revaluation.
When the company sells Bitcoin, the taxable gain is the proceeds minus the original cost basis. That gain is subject to CGT at the corporate rate: 80% of the gain is included in taxable income and taxed at 28%, producing an effective CGT rate of 22.4%. The accounting gain and the SARS gain will often differ because the accounting value updates to fair value each reporting period while the SARS cost basis remains fixed at original purchase price until disposal.
A company holding Bitcoin that has appreciated in value carries two numbers: the fair value for financial reporting and the original cost basis for SARS. Both must be tracked separately and both must be reported in the annual tax return. Losing the cost basis documentation creates a reconciliation problem when disposal eventually occurs.
One additional point: if the company generates income from Bitcoin staking or yield, SARS treats that as business income taxable at the full corporate rate, not at the capital gains rate. Directors considering yield-generating Bitcoin strategies need to account for this distinction.
Board Resolution and Authority
Before the company acquires Bitcoin, the board must pass a resolution approving the decision.
The resolution should specify the purpose of the holding (treasury reserve, investment, operational hedge), the rand amount to be allocated, the custody arrangement, and the director or executive authorised to manage the position. Without a board resolution, a director acting unilaterally to purchase Bitcoin with company funds creates a governance problem, regardless of how the investment performs.
The company’s memorandum of incorporation must also permit the investment. Most modern MOIs grant directors broad authority to invest company funds. If the MOI is restrictive and lists only specific permitted investments, a shareholders’ resolution to amend it may be needed before Bitcoin can be purchased.
For listed companies, the threshold is higher. The audit committee must oversee the risk management of the Bitcoin position and the board must be prepared to disclose the decision to shareholders. Surprises in financial statements are not acceptable for listed entities.
Custody for Corporate Bitcoin
The company’s Bitcoin must be held in the company’s name, not in any individual director’s personal account or exchange wallet.
Corporate Bitcoin requires segregated custody: the company’s holdings must be clearly separated from any custodian’s own assets and from other customers’ assets. Exchange custody pools all customer Bitcoin together, which means the company’s Bitcoin is mingled with others and exposed to the exchange’s solvency and security posture. That is not an acceptable arrangement for a company treasurer.
Multi-signature custody is the correct model at corporate scale. SimplB’s Vault uses a 2-of-3 structure: the company controls one signing key, SimplB controls a second, and a third independent key can be held separately. No single party can move the Bitcoin unilaterally. Every transaction requires at least two keyholders to sign. The company can verify its Bitcoin balance independently at any time without relying on a custodian’s assurance.
The company must maintain custody agreements and periodic statements from the custodian as part of its financial controls. These are reviewed by the audit committee and form part of the auditor’s verification process. For very large holdings, a multi-custodian approach across two or three providers can reduce concentration risk further.
The Africa Bitcoin Corporation Example
Africa Bitcoin Corporation, listed on the JSE, provides a practical reference point for how corporate Bitcoin treasury works in South Africa.
ABC raised capital specifically to hold Bitcoin as a treasury asset. The Bitcoin holding is disclosed to shareholders. Fair value measurement is applied at each reporting period and the resulting gains or losses appear in the income statement. The structure is legal, the accounting is transparent, and the disclosure framework is in place. Directors considering a corporate Bitcoin position can use ABC as a reference for what compliant disclosure looks like under JSE requirements.
ABC is not the only model, but it demonstrates that the structure exists, has been implemented and has passed JSE scrutiny.
Listed Company Disclosure
A listed company holding a material Bitcoin position must disclose it to shareholders.
The annual financial statements must include the amount held, the cost basis, the fair value at reporting date, the unrealised gain or loss, the custody arrangement and the purpose of the holding. Shareholders are entitled to understand what Bitcoin exposure the company carries and what risk that creates.
The auditor must verify the existence of the Bitcoin through the custodian, confirm the fair value measurement and ensure accounting compliance with IAS 38 or IFRS 9. If Bitcoin’s price moves materially between reporting dates, or if the company’s position changes materially, a SENS announcement may be required within the JSE’s prescribed timeframe.
Directors of listed companies should treat Bitcoin disclosure the same way they treat any other material asset class: with consistent, accurate and timely reporting. Failing to disclose a material Bitcoin position or disclosing it late creates regulatory exposure.
Unlisted Company Holdings
Private companies face fewer disclosure requirements but carry the same accounting and tax obligations.
The directors of a private company must maintain proper accounting records, document the board decision to hold Bitcoin, and comply with SARS tax requirements including tracking cost basis and reporting disposals. Private companies are not required to publish annual financial statements publicly, but the records must exist and must be available for SARS audit.
Shareholders of a private company are still entitled to financial information. If the Bitcoin holding is material to the company’s net asset value, shareholders should be informed. Governance obligations do not disappear simply because the company is unlisted.
Risk Management and Controls
The board’s risk committee should treat Bitcoin like any other treasury asset: with regular review, documented policy and clear decision authority.
Minimum controls include quarterly verification of the Bitcoin balance through the custodian, monitoring of fair value and its impact on the company’s financial position, a documented policy on when the position should be reduced or sold, and board minutes recording every material decision about the holding.
Directors should be clear-eyed about volatility. A R50 million Bitcoin position can move R5 to R10 million in a week. If that level of swing in reported assets is unacceptable to the board, shareholders or lenders, the position size needs to reflect that constraint. Volatility is not a reason to avoid Bitcoin as a treasury asset, but it is a reason to size the position proportionately and document the board’s appetite for it explicitly.
Practical Steps for a Director
- Confirm that the company’s MOI permits Bitcoin as an investment. If not, seek a shareholders’ resolution to amend it before proceeding.
- Obtain board approval. The resolution must specify purpose, rand amount, custody arrangement and authorised persons.
- Consult with the company’s auditors on accounting classification. Confirm whether IAS 38 or IFRS 9 is appropriate for the company’s specific holding strategy.
- Select a custodian. The Bitcoin must be held in the company’s name in a multi-signature segregated structure.
- Open a corporate account. The company, not the director personally, is the account holder. Personal accounts are not acceptable for corporate holdings.
- Establish a written Bitcoin treasury policy. Document acquisition limits, disposal criteria, authorisation levels and custody review schedule.
- For listed companies: disclose the Bitcoin holding in financial statements and via SENS as required by JSE rules.
- Maintain documentation: custody agreements, fair value valuations at each reporting date, disposal records and board minutes approving every material change in the position.
- Comply with SARS requirements. Track the cost basis separately from the accounting fair value. Report disposals in the annual tax return. Include Bitcoin as an asset in the company’s return.
- Review the position annually. The board should assess whether the holding size remains appropriate for the company’s strategy, risk appetite and financial position.
Frequently Asked Questions
Can a South African company legally hold Bitcoin as a treasury asset?
Yes. South African company law does not prohibit Bitcoin holdings and the JSE has adopted the IASB’s 2024 guidance under IAS 38, which provides a clear accounting framework. The company’s memorandum of incorporation must permit the investment and the board must pass a resolution approving it. Beyond those internal governance steps, no regulatory approval from SARS, SARB or FSCA is required to hold Bitcoin as a treasury asset.
How does SARS tax Bitcoin held by a company?
SARS treats Bitcoin held as a capital asset. The tax event is disposal: when the company sells Bitcoin, the gain (proceeds minus original cost basis) is subject to CGT. The corporate effective CGT rate is 22.4% (80% inclusion taxed at 28%). Unrealised fair value gains recognised in financial statements are not taxed by SARS until an actual disposal occurs. The company must maintain the original cost basis separately from the accounting fair value and report disposals in its annual tax return.
What custody arrangement is required for corporate Bitcoin?
The Bitcoin must be held in the company’s name in a segregated custody arrangement, not in a personal account and not in a pooled exchange wallet. Multi-signature custody is the appropriate model: multiple private keys are required to authorise any transaction, meaning no single person or institution can move the Bitcoin unilaterally. The company must maintain custody agreements, periodic statements from the custodian and records sufficient for audit verification.
What board approvals does a director need before purchasing Bitcoin for the company?
The board must pass a formal resolution before any Bitcoin is purchased. The resolution must specify the purpose of the holding, the amount to be allocated, the custody arrangement and the person authorised to manage the position. For listed companies, the audit committee must also be briefed and the risk management framework for the holding must be documented. If the company’s MOI does not permit Bitcoin investments, a shareholders’ resolution to amend the MOI is required before the board resolution can authorise any purchase.
What must a listed company disclose about its Bitcoin holdings?
A listed company must disclose material Bitcoin positions in its annual financial statements, including the cost basis, fair value at reporting date, unrealised gain or loss, custody arrangement and intended purpose. If the Bitcoin position changes materially between reporting dates, a SENS announcement may be required. The external auditor must verify the existence of the Bitcoin through the custodian and confirm the fair value measurement meets IAS 38 requirements. Late or incomplete disclosure of a material Bitcoin position creates regulatory exposure under JSE rules.
What is the difference between the accounting value and the tax value of corporate Bitcoin?
The accounting value is the fair market price of the Bitcoin at each reporting date, updated each quarter or year under IAS 38. The SARS tax value is the original cost basis at which the company purchased the Bitcoin, fixed at that amount until an actual disposal occurs. These two figures diverge whenever Bitcoin’s price moves and no sale has taken place. A company that bought Bitcoin for R5 million and now holds it at a fair value of R9 million has a R4 million unrealised gain in its accounts but no tax liability yet. When the Bitcoin is eventually sold, SARS will tax the gain based on the original R5 million cost basis, regardless of interim accounting values.
