Corporate Roll-Over Relief (ss 41–47): The Complete Guide

Why the corporate rules exist

For tax purposes, almost any transfer of an asset is a disposal. A donation, or a disposal for a consideration that cannot be measured in money, can trigger the market-value rule, and a connected-person transaction must also pass the arm’s-length test in paragraph 38 of the Eighth Schedule. A disposal can produce income tax, recoupments or CGT, depending on the asset and its tax treatment. Without special rules, a group tidy-up, merger or move of a property into a company could trigger tax on paper profits, even though the same people still own the same assets at the end of the day.

Parliament’s answer is Part III of the Act. Its own heading tells you exactly what it covers:

The thinking is simple: where a genuine reorganisation merely changes the legal wrapper around an asset — the same economic owners keep the same economic exposure — the tax system should not force a tax bill that would otherwise make sensible restructuring impossible.

Deferral, not forgiveness

Most of the tools use the same basic machine. The person transferring the asset is treated as disposing of it at its tax cost (base cost for a capital asset, tax value for trading stock) — so no gain arises now. The person receiving the asset inherits that tax cost and the original acquisition date, standing in the transferor’s shoes. The built-in gain does not disappear; it travels with the asset, and the deferred amount is brought to account when the asset is eventually disposed of outside the relief — with the actual tax then depending on the proceeds, deductions, losses and law in force at that time. Two of the tools work differently in the detail: s 43 rolls the holder’s own cost into a replacement share, and s 46 splits an existing shareholder’s cost between two shareholdings rather than moving an asset at all — each spoke guide covers its own mechanics.

Two practical consequences follow. First, whether a roll-over is worth using depends on the gains, recoupments, the asset’s tax history, the other transaction taxes and the planned exit. Not every corporate-rule transaction requires an existing capital gain: s 42, for example, needs a market value equal to or above tax cost, and the other sections have their own rules for assets standing at a loss — check the specific section. Second, because the gain survives inside the structure, the exit is where SARS focuses its attention — which is why the anti-avoidance layer (below) matters as much as the relief itself.

The six roll-over tools at a glance

The six sections each address a distinct reorganisation pattern. The spoke guides below the grid walk through each in full — requirements, mechanics, traps and a worked example. In brief:

• s 42 — Asset-for-share: you hand an asset to a resident company and take new shares in exchange — the classic way to move a property or business into a company.
• s 43 — Substitutive share-for-share: a defined substitution of a linked unit for an equity share that is not a linked unit in the same company (historically, property-fund linked units becoming ordinary shares). A qualifying swap has no immediate gain or loss — a deemed disposal at your own tax cost, not a tax-free event.
• s 44 — Amalgamation: two companies become one: the amalgamated company transfers everything to the resultant company, its shareholders take shares in the survivor, and it is then terminated.
• s 45 — Intra-group: an asset moves between two companies in the same 70% group with the income tax deferred if the transaction qualifies — the workhorse of group restructures, with the fiercest anti-avoidance.
• s 46 — Unbundling: a company distributes the shares of a subsidiary to its own shareholders, so they hold both companies directly, side by side — strict gateways decide who may receive the shares with relief.
• s 47 — Liquidation distribution: a subsidiary being wound up passes all its assets up to its group holding company at tax cost, then disappears.

Two of these need a company to actually disappear: s 44 and s 47 both require the transferring company to take the statutory steps to be liquidated, wound up or deregistered within 36 months (or a longer period allowed by SARS), failing which the relief is reversed. That is a deadline for taking the steps, not necessarily the date by which CIPC must have finished the process.

The rules that override the relief

The corporate rules are powerful — s 41(2) makes them apply “notwithstanding any provision to the contrary” in the Act. But the same subsection then lists the provisions that beat the corporate rules. This carve-out list is the single most important sentence in the whole of Part III:

In plain language: even a perfectly executed roll-over can still be trumped by the value-mismatch rules (s 24BA — issuing shares worth more or less than the asset), the general anti-avoidance rule (GAAR, ss 80A–80L), the assessed-loss and avoidance rules in s 103, the value-shifting rules in the Eighth Schedule, and the foreign-exchange and interest-instrument rules (ss 24I and 24J). We unpack each of these — with the 2026 court decisions that show them in action — in The Rules that Override Roll-Over Relief.

The other taxes: transfer duty, STT and VAT

Income tax is only one of the taxes that can bite when an asset moves. Three separate exemptions are linked to the corporate rules — related, but each standing on its own statute, conditions and paperwork. The Transfer Duty Act exempts property acquired by a company under a qualifying s 42, 43, 44, 45 or 47 transaction (s 9(1)(l), limbs (i), (iA), (iB), (ii), (iii) and (iv)), on a sworn affidavit by the company’s public officer. The Securities Transfer Tax Act exempts share transfers made under the corporate rules (s 8(1)(a)), again on the public officer’s sworn declaration and subject to the Act’s timing requirements. And the VAT Act contains a deeming rule (s 8(25)) treating vendor parties to a qualifying s 42, 44, 45 or 47 supply as one and the same person — with going-concern (or fixed-property leaseback) conditions attaching to the s 42 and s 45 limbs specifically, and a written election for those limbs into the ordinary zero-rating rules instead. None of these applies automatically because the income-tax relief does — see VAT & Securities Transfer Tax When Restructuring and Transfer Duty & the Section 42 Exemption.

Note — an election out of a roll-over (most of the sections allow one in writing) changes the income-tax treatment. Its effect on STT, transfer duty and VAT must be checked under each Act’s own provisions, and the answer is not simply “the exemptions fall away”: the STT exemption refers to a transfer “in terms of an asset-for-share transaction referred to in section 42” — a definitional test — and in BPR 195 (2015) SARS ruled it applied although the parties had elected under s 42(8A) that the s 42 relief would not apply. The transfer-duty exemption uses similar wording without a published ruling. Either way the public officer must swear the acquisition complies with the exempting paragraph, so re-do the entry-tax analysis before you opt out.

Time limits and clawbacks

Every tool carries its own guard-rails, but four recur across the Part and are worth knowing from the start:

The 18-month rules. Several, but not all, of the corporate rules attach special consequences to a disposal within 18 months — ss 42, 44, 45 and 47 each have their own version, with their own triggers and outcomes; ss 43 and 46 have no equivalent early-disposal rule (though other anti-avoidance rules can still apply). Section 42 alone has three separate rules, which should not be read as one holding period: s 42(5) (an early sale of the shares, but only where its asset-composition test is met), s 42(6) (ceasing to hold the specified qualifying interest, or stopping the qualifying full-time service — which can apply without a sale, for example on a dilution, and treats the roll-over shares still held as sold and reacquired at their market value on the original transaction date, subject to specific exceptions) and s 42(7) (the company selling the asset early). Where an early asset sale is caught, the restriction generally applies to the historic amount the subsection specifies, not automatically to the whole later gain. Record the implementation date and check the rule for the specific section used before any later disposal or distribution.

The six-year degrouping charge (s 45(4)). If the companies stop being part of the same group within six years of an intra-group transfer, and the transferee still holds the asset, a deferred amount calculated under s 45(4) is brought to account in the transferee — the single biggest trap in group restructuring. The rule has its own asset-retention, tracing and calculation requirements; it belongs to s 45 transfers and is not a general six-year charge on every liquidation or restructuring.

The 36-month termination requirement (ss 44(13) and 47(6)). Amalgamations and liquidation distributions are conditional on the disappearing company actually taking the statutory steps (s 41(4)) to liquidate, wind up or deregister within 36 months, or a longer period allowed by SARS. That is not necessarily the date by which CIPC must have completed the process — but the steps must also not be withdrawn or invalidated in the way the section prohibits.

Extraordinary dividends (para 43A). Stripping value out as “exempt” dividends within 18 months before a share disposal converts those dividends into taxable proceeds — and the 2026 Company AF judgment shows SARS reaching the same result under GAAR even for older transactions. See Dividend Stripping & the 18-Month Web.

Before signing

Roll-over relief depends on the exact parties, share rights, asset tax classification, values, residence, VAT status, debt assumed, consideration received and the order of steps. Obtain transaction-specific tax and legal advice before agreements or resolutions are signed — a later correction may not restore the relief.
