What counts as an amalgamation
The definition has three moving parts: everything must go across, it must go across by way of an amalgamation, conversion or merger, and the transferring company must be on its way out of existence.
“‘amalgamation transaction’ means any transaction— (a)(i) in terms of which any company (hereinafter referred to as the ‘amalgamated company’) which is a resident disposes of all of its assets (other than assets it elects to use to settle any debts incurred by it in the ordinary course of its trade and other than assets required to satisfy any reasonably anticipated liabilities to any sphere of government of any country and costs of administration relating to the liquidation or winding-up) to another company (hereinafter referred to as the ‘resultant company’) which is a resident, by means of an amalgamation, conversion or merger; and (ii) as a result of which the existence of that amalgamated company will be terminated;”
Note what the brackets allow the disappearing company to keep back: assets used to settle ordinary-course debts, assets needed for anticipated tax and government liabilities, and winding-up admin costs. Everything else must go to the resultant company. A transfer of merely most of the business, with the shell continuing to trade, is not an amalgamation — it is an asset sale, taxed normally (or structured under s 42 or s 45 if those definitions fit). And the converse is equally true: a transaction is not a tax “amalgamation” merely because one company happens to transfer all its assets — it must take place by means of an amalgamation, conversion or merger, and the termination requirement must be satisfied.
Note — the definition also has cross-border limbs: para (b) covers a foreign company amalgamating into a resident company, and para (c) covers two foreign companies within the same group where the survivor is a controlled foreign company. This guide concentrates on the domestic para (a) transaction.
Step 1 of 5 · Before
The company-level roll-over
Where the definition is met, the disappearing company is treated as selling each capital asset at its base cost — so no gain — and the survivor steps into its shoes completely:
“Where an amalgamated company disposes of— (a) a capital asset in terms of an amalgamation transaction to a resultant company which acquires it as a capital asset— (i) the amalgamated company must be deemed to have disposed of that asset for an amount equal to the base cost of that asset on the date of that disposal; and (ii) that resultant company and that amalgamated company must, for purposes of determining any capital gain or capital loss in respect of a disposal of that asset by that resultant company, be deemed to be one and the same person…”
The same one-and-the-same-person logic runs through the rest of the section: trading stock rolls over at its tax value (s 44(2)(b)), and for allowance assets — machinery, buildings and other assets on which wear-and-tear or building allowances have been claimed — no recoupment is triggered and the survivor simply continues the allowance history (s 44(3)). The survivor also inherits a slice of the disappearing company’s contributed tax capital (s 44(4A)), so the group’s capacity for capital repayments outside the dividends-tax net is preserved in proportion.
Note — SARS Interpretation Note 146 (2 September 2026) explains the limited purpose of the “one and the same person” deeming in s 44(3)(a). It does not merge the two companies into a single taxpayer for every purpose, and both cannot claim the same allowance for the year of transfer: an allowance that is apportioned by period (s 11(e) wear-and-tear) is split between them, while a non-apportioned allowance (s 12C) stays with the company that qualified for it in the year of the transfer, with the survivor claiming from the following year. SARS says the same principles apply to the equivalent deeming in ss 42, 45 and 47.
Cash and other extras: boot and deemed dividends
Cash and other consideration received instead of equity shares require two separate checks. First, the general boot rule: to the extent the consideration is anything other than equity shares in the resultant company (or the permitted assumption of old ordinary-course debt), the roll-over does not apply to that part (s 44(4) at company level). At shareholder level, s 44(6)(d) works proportionally: it excludes from the roll-over the part of each old share that bears the same ratio to the share as the other consideration bears to the full consideration — and that slice is taxed as a normal disposal.
Secondly, and easily missed: s 44(6)(e) can treat non-share consideration as an amount distributed by the disappearing company, for the purposes of the statutory “dividend” and “return of capital” definitions. That rule is capped: it applies only to so much of the other consideration as does not exceed the market value of all the company’s assets immediately before the merger, less its liabilities and the contributed tax capital of all its share classes. The resulting amount must then be classified under the dividend and return-of-capital definitions. It is not simply “cash received minus contributed tax capital”. Whether dividends tax is then actually payable depends on those definitions, the company’s allocation and any applicable dividends-tax exemption — but the design message is plain: an amalgamation is not a mechanism for pulling value out in cash; it is a mechanism for continuing ownership in a new wrapper.
Termination: the steps to take within 36 months
The whole bargain rests on the amalgamated company actually disappearing. Section 44(13) is blunt about what happens if it does not:
“The provisions of this section do not apply where the amalgamated company— (a) has not, within a period of 36 months after the date of the amalgamation transaction, or such further period as the Commissioner may allow, taken the steps contemplated in section 41 (4) to liquidate, wind up or deregister; or (b) has at any stage withdrawn any step taken to liquidate, wind up or deregister that company … Provided that any tax which becomes payable as a result of the application of this subsection may be recovered from the resultant company.”
The “steps” are defined in s 41(4): lodging the voluntary winding-up resolution (Companies Act s 80(2)), or filing the deregistration request (Companies Act s 82(3)(b)(ii)) or the amalgamation/merger notice (Companies Act s 116) with the CIPC, plus disposing of all assets, settling liabilities, and having the company’s tax filings up to date. What must happen within 36 months (or a longer period SARS allows) is that those steps are taken — that is not necessarily the date by which the CIPC must have completed the process — and a step, once taken, must never be withdrawn or invalidated. If the steps are not taken in time, the entire relief unravels — with the tax collectable from the surviving company. Diarise this deadline on day one of the transaction, not at month 30.
The 18-month asset rule and other guard-rails
The 18-month rule (s 44(5)). If the survivor sells a rolled-over asset within 18 months, the historic gain (up to the asset’s value at the start of the period) is calculated separately and restricted: a capital gain’s resulting taxable capital gain cannot be set off against the survivor’s assessed losses, trading-stock and allowance amounts are deemed to belong to a separate trade with the same restriction, and matching rules quarantine early capital losses. The deferred history does not become ordinary profit-and-loss material for a year and a half.
Group amalgamations (s 44(14)(g)). Where the amalgamating companies and the shareholder are all in the same group, the parties may jointly elect out of s 44 for the asset transfers — useful where the group prefers the s 47 liquidation route or wants a different base-cost outcome. Section 44(14) also excludes certain resultant companies altogether (non-profit companies, tax-exempt entities and certain collective investment scheme mismatches).
Assessed losses do not travel. Nothing in s 44 transfers the disappearing company’s assessed loss to the survivor — the loss cannot be carried across, though the amalgamated company’s own use of it in its final period remains subject to the ordinary rules. And structuring share deals around a loss company walks straight into s 103(2). See The Rules that Override Roll-Over Relief.
Companies Act mechanics. The tax definition (“amalgamation, conversion or merger”) is broader than the Companies Act’s statutory merger in ss 113–116 — a scheme of arrangement or even a contractual all-assets transfer can qualify — but where the statutory merger is used, the s 116 notice of amalgamation doubles as a s 41(4) termination step. The company-law and tax tracks must be planned together.

The Pienaar Brothers warning
Section 44 carries the corporate rules’ most famous cautionary tale. In the mid-2000s, a scheme did the rounds: use a s 44 amalgamation to shift a business into a new company loaded with share premium, then distribute that premium to shareholders free of the secondary tax on companies of the day. Parliament shut this down by inserting s 44(9A) — and made the amendment retrospective. The sequence matters: SARS announced on 21 February 2007 that the exemption was withdrawn “with immediate effect” and published a draft Bill on 27 February; Pienaar Brothers signed its agreement on 16 March 2007, transferred the business on 1 April and distributed the premium on 3 May; the revised Bill followed on 7 June and the Act on 8 August 2007, with s 44(9A) deemed to have come into operation on 21 February 2007. The company — which had implemented after the announcement but before the Act — was assessed under the backdated provision and challenged it as unconstitutional.
The lesson for anyone restructuring today is not about share premium (that scheme is long dead). It is this: a structure that works only because of a gap in the corporate rules is exposed even after implementation — Parliament has closed such gaps backwards in time, and the courts have let it. Build amalgamations on commercial substance, not drafting accidents. The full judgment story is in What the Courts Actually Say.
Frequently asked questions
It is the Income Tax Act’s roll-over merger: one resident company transfers all of its assets to another resident company by amalgamation, conversion or merger, its shareholders take shares in the survivor, and the transferring company is terminated. Where every requirement is met, assets and shares roll over at tax cost with no immediate income tax or CGT; the gain is deferred, not forgiven.
The amalgamated company must take the formal liquidation, winding-up or deregistration steps in s 41(4) within 36 months (or a period SARS extends) and never withdraw them; CIPC need not have completed the process by then, but dormancy alone is not a step. If the steps are not taken in time, s 44(13) switches the relief off retrospectively — and the resulting tax can be recovered from the surviving company. Reversing a step already taken has the same effect.
Only at a price, and two separate checks apply. First, s 44(6)(d) takes the matching portion of the old shares out of the shareholder roll-over, so that portion is taxed as an ordinary disposal. Secondly, s 44(6)(e) can treat the cash or other non-share consideration as an amount distributed by the disappearing company. That second rule is capped by the market value of the company’s assets immediately before the merger, less its liabilities and the contributed tax capital of all its share classes; the resulting amount is then classified under the dividend and return-of-capital definitions. It is not simply “cash received minus contributed tax capital”. A s 44 merger is designed for continuing shareholders, not exiting ones.
No. Assets, base costs, allowance histories and a proportion of contributed tax capital roll over — but an assessed loss stays behind and dies with the amalgamated company. Transactions built to traffic in a company’s assessed loss are attacked separately under s 103(2).
Not necessarily — the tax definition covers any “amalgamation, conversion or merger”, including schemes of arrangement and contractual all-assets transfers. But the Companies Act ss 113–116 statutory merger is the natural fit, and its s 116 filing conveniently doubles as a termination step for s 41(4). Plan the tax and company-law tracks together from the start.
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.
