What a beneficiary is
A trust exists for its beneficiaries — the people the trustees may benefit. In law a beneficiary is anyone with an interest in the trust’s income, accruals or assets, whether that interest is already vested (fixed) or merely contingent (dependent on a future event). The Income Tax Act draws the line wide, and SARS reads it wider still: a person does not have to be receiving anything yet to count as a beneficiary.
“beneficiary” in relation to a trust means a person who has a vested or contingent interest in all or a portion of the receipts or accruals or the assets of that trust; [IN 67 adds:] This definition is wide and includes capital and income beneficiaries with vested rights and discretionary beneficiaries … A contingent beneficiary whose rights are dependent upon, for example, reaching a specific age, will … also be a ‘beneficiary’ prior to that date.
Note — Interpretation Note 67 (Connected Persons) quotes the s 1(1) definition and explains its breadth. Note the closing qualifier in the wide reading: a contingent right counts provided that these have been designated as such in the trust instrument.
A beneficiary’s entitlement usually relates either to the income the trust earns (interest, rent, dividends) or to its capital (the assets themselves) — and the same person can hold both. Whether that entitlement is fixed or discretionary is set by the trust deed, and it is the single most consequential fact about any beneficiary. For where beneficiaries sit alongside the founder and trustees, see founder, trustee and beneficiary.
Vested vs discretionary rights
A vested right is an unconditional, enforceable right: the trust deed already entitles the beneficiary to a specified amount or share, and the trustees must pay it over. A discretionary (contingent) interest is the opposite: the trustees decide whether, when and how much to distribute, and until they exercise that discretion the beneficiary holds only a hope — a spes — and nothing a court will order paid. SARS’s trust-return guide puts the distinction plainly.
Under a vesting trust the income or capital gain or assets of the trust are vested in the beneficiaries and the beneficiaries are said to have vested rights … Under a discretionary trust, the trustees usually have the discretion as to whether and how much of the income or capital of the trust to distribute to the beneficiaries[; the beneficiaries] merely have contingent/discretionary rights (hope or spes) …
The practical difference runs through everything. A vested right can be enforced, ceded and — because it is an asset of the beneficiary — attached by that beneficiary’s creditors. A discretionary interest cannot be enforced, ceded or attached, because there is no right to attach until the trustees act. That is why the overwhelming majority of South African family trusts are fully discretionary: it gives the trustees flexibility each year and gives beneficiaries the strongest asset protection.
How rights drive the tax: the section 25B conduit
The vested/discretionary distinction is not just about enforcement — it decides who pays the tax. A trust is treated as a conduit, a pipe: income it receives and then vests in a resident beneficiary in the same year is taxed in that beneficiary’s hands, not the trust’s. Only what stays in the trust is taxed in the trust — at the flat 45% rate.
Any amount … received by or accrued to … any person … in his or her capacity as the trustee of a trust, shall, subject to the provisions of section 7, to the extent to which that amount has been derived for the immediate or future benefit of any ascertained beneficiary, who is a resident and has a vested right to that amount during that year, be deemed to be an amount which has accrued to that beneficiary, and to the extent to which that amount is not so derived, be deemed to be an amount which has accrued to that trust.
The income keeps its character on the way through — interest is still interest, rent still rent — and it is taxed at the beneficiary’s own marginal rate, which for most family members is far below 45%. That flow-through is the whole point of using a discretionary trust: the trustees vest income in the right beneficiaries each year rather than letting it stack up and be taxed at the top rate. The full mechanics, including the 45% trust rate and the 36% effective CGT rate, are in our guide to how trusts are taxed.
Minors and attribution: when the tax loops back to the founder
A minor — a person under 18, the age of majority under section 17 of the Children’s Act 38 of 2005 — can be a beneficiary, and trusts are one of the best ways to hold assets for children. But the conduit does not reliably save tax for a minor. Where a child benefits because of a donation, settlement or other disposition by a parent, the Act taxes the parent instead.
Income shall be deemed to have been received by the parent of any minor child or stepchild, if by reason of any donation, settlement or other disposition made by that parent of that child— (a) it has been received by or has accrued to or in favour of that child or has been expended for the maintenance, education or benefit of that child; or (b) it has been accumulated for the benefit of that child.
How SARS matches IT3(t) data to the beneficiary’s return
Beneficiary tax is no longer something a trust can quietly self-assess. A resident trust must file an annual IT3(t) return reporting every amount it vested in a beneficiary — income, capital gains and capital distributions — in addition to its own trust return (the ITR12T). SARS then matches that third-party data against what each beneficiary reports, so a distribution declared by the trust must line up with the beneficiary’s return. The trust-return guide is explicit that it is the rights conferred — vested versus discretionary — that drive who is taxed.
Frequently asked questions
A vested beneficiary already holds a fixed, enforceable right — the trustees must pay it over. A contingent (discretionary) beneficiary holds only a hope (spes) that depends on a future event, such as reaching a set age or the trustees exercising their discretion. Both are “beneficiaries” under s 1(1) of the Income Tax Act, but only the vested right is enforceable and only it draws income to that person under the s 25B conduit.
Only where the right has vested. A vested beneficiary can ask a court to compel payment because the trustees have no discretion to withhold. A purely discretionary beneficiary cannot — until the trustees exercise their discretion there is no enforceable claim, only a spes. They can still challenge a decision made in bad faith, for an improper purpose, or in breach of the trustees’ fiduciary duty.
Usually yes, where the income vests in or is distributed to a resident beneficiary in the same year the trust earns it. Section 25B treats that amount as having accrued to the beneficiary, taxed at their own marginal rate, and the income keeps its character. The conduit only works for a resident beneficiary with a vested right — otherwise it stays taxable in the trust, and attribution under s 7 can pull it back to the founder.
Yes. A minor — a person under 18, the age of majority under s 17 of the Children’s Act 38 of 2005 — can be a beneficiary, and protecting minors is one of the main reasons trusts exist. But vesting income or a gain in a minor child generally does not save tax: s 7(3) and paragraph 69 attribute it back to the funding parent. See minor children and attribution.
Yes. A deed can define beneficiaries as a class — for example “the descendants of the founder” — automatically capturing future and unborn members without amendment, provided the class is certain enough to apply. For the Master’s beneficial-ownership register, every beneficiary named in the instrument must still be recorded — see trust reporting and registers.
