South African trust law recognises several distinct types of trust, each created for a different purpose and governed by different rules. Understanding the difference between an inter vivos trust and a testamentary trust is fundamental to effective estate planning, asset protection, and family wealth structuring. For a broader overview of how trusts work in general, see our comprehensive guide to trusts in South Africa.
All trusts in South Africa are governed primarily by the Trust Property Control Act 57 of 1988, which prescribes how trusts are registered, administered, and wound up. The Income Tax Act 58 of 1962 and the Estate Duty Act 45 of 1955 determine the tax treatment of trusts and trust assets — a critical consideration when selecting the right structure. This guide examines each trust type in detail.
What is an Inter Vivos Trust?
An inter vivos trust — from the Latin inter vivos, meaning "among the living" — is a trust created and registered during the founder's lifetime. It is the most commonly used trust structure in South African estate planning and asset protection because it comes into existence immediately upon registration with the Master of the High Court, and continues to exist after the founder's death. The assets held in an inter vivos trust fall outside the founder's deceased estate, which has significant implications for estate duty, executor fees, and the continuity of asset ownership.
Key Characteristics of an Inter Vivos Trust
- Created during the founder's lifetime: The trust deed is executed and the trust is registered with the Master of the High Court while the founder is alive. The T62 application form is filed and Letters of Authority are issued to the trustees before any assets are transferred.
- Assets fall outside the deceased estate: Once assets have been validly transferred into the trust, they belong to the trust — not the founder. On the founder's death, those assets are not part of the deceased estate and are therefore not subject to executor's fees or estate duty on any growth that has accrued within the trust.
- Donations tax implications on transfer: Transferring assets into an inter vivos trust during the founder's lifetime constitutes a donation for tax purposes. Donations tax is levied at 20% on amounts up to R30 million (25% above that), subject to the annual R100,000 exemption. Loans between the founder and the trust, often used instead of outright donations, carry their own interest and transfer pricing considerations.
- Continuity after death: The trust continues to operate after the founder's death, governed by the trust deed and administered by the trustees. This makes it ideal for business succession, family property holdings, and ensuring that assets remain intact for the benefit of future generations.
- Amendable during the founder's lifetime: If the trust deed permits it, the founder (with the consent of trustees and beneficiaries) may amend the deed during their lifetime. Once the founder dies, the trust deed becomes immutable — it governs the trust for the rest of its existence.
- Founder may also be a trustee and beneficiary: South African law permits the founder to serve as a trustee and even as a beneficiary, provided the trust deed is structured carefully to avoid the trust being deemed a "sham" or a "pure bequest" arrangement by SARS or the courts. An independent trustee is strongly recommended.
The inter vivos trust is particularly powerful for asset protection because, once assets are properly transferred, they are shielded from the founder's personal creditors (subject to the insolvency Act's claw-back provisions for dispositions made within certain periods before insolvency). For a step-by-step guide to registration, costs, and documentation, see our article on how to set up a trust in South Africa.
Important: Sham Trust Risk
SARS and the courts scrutinise inter vivos trusts carefully. If the founder retains effective control over all trust assets and decisions — acting as if the trust does not exist — the trust may be disregarded for tax purposes (section 7C of the Income Tax Act) or set aside entirely. Independent trustees, proper record-keeping, and genuine transfer of assets are essential to maintaining the trust's legal integrity.
What is a Testamentary Trust?
A testamentary trust is a trust created by a will (testament) and only comes into existence on the death of the testator. Unlike an inter vivos trust, it has no legal existence during the testator's lifetime — it is merely a provision in the will that instructs the executor to establish a trust and transfer specified assets into it after death. The assets must first pass through the deceased estate, meaning they are subject to estate duty and executor's fees before reaching the trust.
Key Characteristics of a Testamentary Trust
- Created by will, activated on death: The trust exists only on paper until the testator dies. Upon death, the executor winds up the deceased estate, pays estate duty and executor's fees, and then transfers the specified assets to the testamentary trust. The Master of the High Court oversees this process and issues Letters of Authority to the testamentary trustees.
- Assets pass through the deceased estate: Because assets only move into the testamentary trust after the death of the testator, they form part of the deceased estate and are subject to estate duty (levied at 20% on dutiable estate above R3.5 million) and executor's fees (up to 3.5% of the gross value of assets administered).
- Primarily used to protect minor beneficiaries: The testamentary trust's most common application is protecting assets destined for minor children until they reach a specified age (commonly 18, 21, or 25). The trust holds and administers the inheritance on behalf of the minor, preventing reckless dissipation and ensuring professional management.
- Cannot be amended after the testator's death: Once the testator has died and the trust comes into operation, its terms are fixed by the will. Only a court of law can deviate from the trust deed in exceptional circumstances — the trustees and beneficiaries cannot simply agree to vary the terms.
- Winds up when beneficiaries reach the specified age: Unlike an inter vivos trust that may endure indefinitely, a testamentary trust typically has a built-in termination date — when the youngest beneficiary reaches the age specified in the will, the trust distributes its assets and is terminated. This makes it a temporary rather than permanent structure.
- Also used for special needs beneficiaries: Beyond minor children, testamentary trusts are frequently used to provide ongoing care and financial support for beneficiaries with disabilities or special needs who may never be able to manage their own affairs.
A well-drafted will including a testamentary trust is one of the most cost-effective ways to protect a minor child's inheritance. However, it offers none of the lifetime asset protection benefits of an inter vivos trust and does not reduce the founder's estate for estate duty purposes. For families with significant assets, an inter vivos trust established during the founder's lifetime will generally provide superior estate planning outcomes.
Side-by-Side Comparison Table
The following table summarises the key differences between inter vivos trusts and testamentary trusts across the most important practical and legal dimensions. Use this as a quick reference when evaluating which trust type best suits your estate planning goals.
| Feature | Inter Vivos Trust | Testamentary Trust |
|---|---|---|
| When created | During founder's lifetime | Only on testator's death |
| Who registers it | Founder files T62 with Master of the High Court | Executor registers with Master after deceased estate is wound up |
| Assets in deceased estate? | No — assets excluded from estate (if properly transferred) | Yes — assets form part of deceased estate before transfer to trust |
| Donations tax? | Yes — on transfer of assets into trust during lifetime | No — estate duty applies instead |
| Executor fees on assets | No — trust assets bypass the deceased estate | Yes — up to 3.5% of gross asset value |
| Estate duty on growth | No — growth accrues within the trust, outside the founder's estate | Yes — full estate duty on the value at date of death |
| Ongoing amendments | Yes — during founder's lifetime (if deed permits) | No — trust deed fixed at death; court order required to deviate |
| Continuity on death | Yes — trust continues uninterrupted | Trust only begins on death; winds up at specified age of beneficiary |
| Privacy | Higher — trust deed not publicly accessible | Lower — will is lodged with the Master and may be accessed by interested parties |
| Setup costs | Higher — professional drafting, Master's fees, asset transfer costs | Lower upfront — incorporated into cost of drafting a will |
| Common uses | Asset protection, business succession, family property, estate duty planning | Protecting minors' inheritances, special needs beneficiaries, spendthrift protection |
Note: The table reflects general principles under the Trust Property Control Act 57 of 1988. Tax implications depend on individual circumstances. Always obtain professional tax advice before establishing or transferring assets into any trust. See our trust costs and fees guide for a breakdown of registration expenses.
Special Trusts Explained
A "special trust" is not a separate category of trust in the sense of its legal structure — it is a tax classification under section 1 of the Income Tax Act 58 of 1962. Special trusts receive preferential income tax treatment: they are taxed at individual marginal rates (up to 45%) rather than the flat 45% rate applied to ordinary trusts, and — crucially — they benefit from the same income tax brackets and rebates that individual taxpayers receive. SARS approval is required for special trust status.
Special Trust Type A — Disabled Beneficiaries
A Special Trust Type A is created solely for the benefit of a person with a disability as defined in section 6B(1) of the Income Tax Act — a condition that has lasted or is expected to last more than a year and results in a limitation of the person's ability to function in daily activities. The trust must have been created solely for the benefit of that person, and no other beneficiary may receive any benefit from the trust during that person's lifetime. Because the beneficiary may never be able to manage their own affairs, the trust provides continuity of care and financial management.
Special Trust Type B — Minor Children of Deceased
A Special Trust Type B is a testamentary trust created solely for the benefit of the minor children of a deceased person, where the youngest child has not yet reached the age of 18. The special trust tax treatment applies for a limited period — effectively within five years of the testator's death — after which the trust loses its special trust status and is taxed at the flat trust rate. This category recognises the financial vulnerability of minor children in the period immediately following a parent's death.
Tax Treatment of Special Trusts
Both types of special trust are taxed at individual marginal rates rather than the flat 45% trust rate. This means the first R237,100 of taxable income (2026/27 threshold) is effectively tax-free, and lower income bands attract lower rates. For a trust holding income-generating assets, the tax saving compared to an ordinary trust can be substantial over time.
SARS Approval Required
Special trust status is not automatic — the trustee must apply to SARS for approval and must demonstrate that the trust meets all the requirements of section 1 of the Income Tax Act. Supporting documentation including the trust deed, Letters of Authority, and medical evidence (for Type A) or the will and death certificate (for Type B) will be required. SARS may withdraw special trust status if the conditions cease to be met.
Practical Consideration
Special trust status is lost permanently if any person other than the qualifying beneficiary receives a benefit from the trust, or if the beneficiary's circumstances change such that they no longer meet the definition. Trustees of special trusts must exercise extreme caution to preserve the trust's qualifying status and should seek professional advice before making any distributions.
Bewind Trusts
A bewind trust is a fundamentally different legal structure from both the inter vivos and testamentary trust. In a conventional trust, the trust itself is the owner of the trust assets — the trustees hold and administer the assets on behalf of the beneficiaries, but the beneficiaries have no direct ownership rights. In a bewind trust, by contrast, the beneficiaries are the owners of the assets. The trustees are appointed only to administer those assets on behalf of the beneficiaries, without holding ownership themselves.
Conventional Trust vs Bewind Trust: The Core Distinction
Conventional Trust
- ✓Trust owns the assets
- ✓Trustees hold title on behalf of beneficiaries
- ✓Beneficiaries have a personal right against the trust
- ✓Assets protected from beneficiary's creditors
Bewind Trust
- ✓Beneficiaries own the assets
- ✓Trustees administer without holding title
- ✓Beneficiaries have a real right in the assets
- ✓Assets may be exposed to beneficiary's creditors
Bewind trusts are most commonly encountered in commercial and property development contexts — for example, where multiple investors co-own undivided shares in a property portfolio and appoint a professional trustee to administer the portfolio on their behalf. They are also used in certain retirement fund and investment structures. Because the beneficiaries are the owners, the asset protection benefits of a conventional trust are largely absent — a creditor of a beneficiary can attach that beneficiary's share of the trust assets.
From a tax perspective, income generated by assets in a bewind trust is attributed directly to the beneficiaries in proportion to their ownership interest, rather than being taxed in the trust at the flat trust rate. This can result in significant tax savings where beneficiaries are taxed at lower marginal rates than the 45% flat trust rate.

Which Type is Right for You?
The right trust type depends entirely on your goals, the nature of your assets, and your family circumstances. The following scenarios illustrate which trust structure is most appropriate in common situations. For detailed guidance on the registration process and what documentation you need, see our article on how to set up a trust.
Asset Protection & Estate Planning
- ✓Inter vivos trust — transfer assets now and freeze estate growth above the donated value
- ✓Growth on trust assets is excluded from your estate, reducing future estate duty exposure
- ✓Ideal if your estate exceeds or is likely to exceed R3.5 million
Protecting Minor Children's Inheritance
- ✓Testamentary trust — low-cost solution built into your will
- ✓May qualify as Special Trust Type B for tax benefits in the first five years
- ✓Specify the age at which children receive their inheritance outright
Caring for a Disabled Family Member
- ✓Inter vivos trust (or testamentary trust) registered as Special Trust Type A
- ✓Individual tax rates apply — significant saving over flat 45% trust rate
- ✓Provides professional, continuous management of care funding
Business Succession & Co-owned Property
- ✓Inter vivos trust — ensures business or property continues uninterrupted after your death
- ✓No need to wind up and re-establish ownership in the hands of heirs
- ✓Trustees can manage day-to-day operations and strategic decisions
Tax Differences at a Glance
Tax is the single most important factor in choosing between trust types — and the rules have become significantly more complex over the past decade. The following summary covers the key tax distinctions. Always obtain advice from a qualified tax practitioner before proceeding, as individual circumstances vary substantially.
Income Tax: Flat Rate vs Individual Rates
Ordinary inter vivos trusts and testamentary trusts are taxed at a flat rate of 45% on all taxable income retained in the trust. This is the same as the top marginal rate for individuals, but without the benefit of tax brackets, rebates, or the primary exclusion. Special trusts (Types A and B) are taxed at individual marginal rates, which can be substantially lower. Distributions of income to beneficiaries in the same tax year are taxed in the beneficiaries' hands, not the trust — making strategic distributions a key planning tool.
Capital Gains Tax (CGT): The 36% Inclusion Rate
Capital gains in ordinary trusts are subject to an inclusion rate of 80% and an effective CGT rate of 36% (compared to 18% for individuals). This is a major disadvantage of trust ownership for appreciating assets where realisation events occur within the trust. Special trusts are taxed at the individual inclusion rate of 40%, giving an effective CGT rate of 18%. Strategic planning around CGT realisation events — for example, timing disposals and attributing gains to beneficiaries — is critical.
Section 7C: Interest-Free and Low-Interest Loans
Section 7C of the Income Tax Act taxes the "forgone interest" on loans made to trusts by connected persons at below the official rate of interest (currently the SARS official rate, linked to the repo rate). The amount of interest foregone is treated as a donation to the trust in the hands of the lender, triggering donations tax. This provision significantly affects the traditional "loan to trust" estate planning strategy and requires careful structuring.
Estate Duty: The Critical Difference
Assets held in an inter vivos trust at the time of the founder's death are not part of the deceased estate and are therefore not subject to estate duty (levied at 20% on dutiable estate above R3.5 million). This is the primary estate duty benefit of the inter vivos trust. Testamentary trust assets, by contrast, are part of the deceased estate and attract full estate duty before being transferred into the trust. The inter vivos trust's estate duty advantage grows over time as the trust accumulates wealth beyond the original donated amount.
Tax Comparison Summary
| Tax | Ordinary Trust | Special Trust | Individual (for comparison) |
|---|---|---|---|
| Income tax rate | Flat 45% | Marginal (18%–45%) | Marginal (18%–45%) |
| CGT inclusion rate | 80% (effective 36%) | 40% (effective 18%) | 40% (effective 18%) |
| Annual exclusion | None | R40,000 (same as individual) | R40,000 |
| Estate duty on assets | No (inter vivos); Yes (testamentary) | No (inter vivos); Yes (testamentary) | Yes — 20% above R3.5m |
Choosing the Right Trust Type for Your Circumstances
The choice between an inter vivos trust and a testamentary trust — and the decision to seek special trust status — depends on your specific estate planning goals, the nature and value of your assets, your family situation, and your long-term objectives. An inter vivos trust provides the most comprehensive asset protection and estate planning benefits, but carries upfront costs and ongoing compliance obligations. A testamentary trust is a cost-effective solution for protecting minors' inheritances, but provides no lifetime benefits. Special trust status can deliver significant tax savings for qualifying beneficiaries.
