Selling or buying a business in South Africa involves a layered set of transaction costs that go well beyond attorney fees. Before you sign a term sheet or heads of agreement, you need a clear picture of what the full transaction will cost — legal fees on both sides, financial and legal due diligence, Competition Commission filing fees if applicable, warranty and indemnity insurance, capital gains tax, VAT, and transfer duty. Failure to budget correctly for these costs can turn a good commercial deal into a painful financial outcome.
This guide provides a transparent, practical breakdown of all the costs involved in selling or buying a business in South Africa — from a small SME asset sale worth R8 million to a large corporate share transaction requiring Competition Commission approval. All fees are exclusive of VAT at 15% unless otherwise stated.
Overview Cost Table
The table below provides indicative cost ranges across the main transaction cost categories, segmented by deal size. Small deals are those with a purchase consideration below R10 million; medium deals are R10 million to R100 million; large deals are above R100 million.
Business Sale Transaction Costs (excl. VAT)
| Cost Category | Small (<R10m) | Medium (R10–100m) | Large (R100m+) |
|---|---|---|---|
| Legal Fees | R25k – R80k | R80k – R250k | R250k – R2m+ |
| Due Diligence | R15k – R60k | R60k – R300k | R300k – R1m+ |
| Competition Filing | N/A | R150k (intermediate) | R500k (large merger) |
| W&I Insurance | N/A | 1–3% of insured amount | 1–3% of insured amount |
| CGT / Tax | Deal-specific | Deal-specific | Deal-specific |
| Transfer Duty | Asset sales only | Asset sales only | Asset sales only |
| Other Advisors | R10k – R30k | R30k – R150k | R150k – R500k+ |
Note: All figures exclude VAT at 15% and are indicative only. Tax costs depend on the deal structure, base cost, and applicable exemptions. Legal fees cover both seller's and buyer's attorneys combined. Transfer duty and Competition Commission filing fees are government charges and are not subject to VAT.

Legal Fees
In every business sale transaction, both the seller and the buyer will typically engage their own attorneys. The seller's attorney drafts the sale agreement (whether a sale of shares agreement or a sale of business agreement), manages the due diligence process from the seller's side, and handles closing mechanics. The buyer's attorney reviews and negotiates the agreement, conducts or coordinates due diligence, and ensures that all conditions precedent are properly fulfilled.
Seller's Attorney Fees
The seller's attorney typically drafts the sale agreement, prepares the disclosure schedule, coordinates the data room, and handles closing. For a small SME sale this might cost R15,000–R50,000. For a medium-sized transaction, expect R50,000–R150,000. On a large or complex deal with multiple closing conditions, regulatory submissions, and protracted negotiations, seller's attorney fees can reach R500,000 or more.
Buyer's Attorney Fees
The buyer's attorney reviews and negotiates the sale agreement, advises on due diligence findings, drafts conditions precedent, and manages closing on the buyer's side. Buyer's attorney fees tend to be comparable to seller's fees — and can exceed seller's fees on complex transactions where the buyer is driving hard on warranty negotiations, pricing adjustments, or escrow mechanics.
Time-Based vs Fixed Fee Billing
Most business sale transactions are billed on a time-and-complexity basis at hourly rates typically ranging from R2,500–R6,000 per hour for experienced commercial attorneys in South Africa. Some attorneys will offer a fixed fee for a defined scope of work — typically the initial draft of the sale agreement and one round of amendments — with additional negotiation rounds billed at an agreed hourly rate. Always clarify the fee structure, what is included, and what triggers additional billing before signing an engagement letter.
What Legal Fees Include
For the quoted fee, your attorney should cover: drafting or reviewing the heads of agreement or term sheet; drafting or negotiating the main sale agreement; preparing or reviewing disclosure schedules and warranties; advising on conditions precedent (regulatory approvals, third-party consents, competition filing); attending to closing mechanics (resolutions, share certificate transfers, CIPC updates, payment mechanics); and post-closing compliance. Ancillary work — such as employment law advice on TUPE-style transfers of employees, conveyancing for immovable property, or tax opinions — is typically billed separately.
Due Diligence Costs
Due diligence is the buyer's investigation of the target business before committing to the transaction. The scope and cost of due diligence depends on the size and complexity of the business, the deal structure (share vs asset), and the risk appetite of the buyer. On most transactions of meaningful size, the buyer will commission financial, legal, and tax due diligence at a minimum.
Due Diligence Cost Breakdown
| DD Stream | Conducted By | Typical Cost (excl. VAT) |
|---|---|---|
| Financial DD | Auditors / accountants | R30,000 – R200,000 |
| Legal DD | Buyer's attorneys | Included in attorney fees |
| Tax DD | Tax advisors | R20,000 – R100,000 |
| IT / Technical DD | IT consultants | R15,000 – R80,000 |
| Data Room Setup | Virtual data room provider | R5,000 – R30,000/month |
Financial due diligence typically involves a review of three years of audited financial statements, management accounts, working capital analysis, debt and liability mapping, EBITDA normalisation, and assessment of the quality of earnings. The cost scales with the size and complexity of the target's financial records and the number of entities in the group.
Vendor due diligence — where the seller commissions their own DD report in advance and makes it available to potential buyers — can significantly reduce the overall due diligence costs on a deal and accelerate the transaction timeline. It is increasingly common on larger transactions and competitive sale processes.
Data room costs depend on whether the seller uses a dedicated virtual data room platform (typically priced by storage volume, number of users, and subscription duration) or simply shares documents via a secure cloud folder. For most SME transactions, a basic shared drive is sufficient. For mid-market and large deals, a purpose-built VDR with activity tracking, document watermarking, and Q&A functionality is recommended.
Competition Commission Fees
Where a business sale transaction meets the merger notification thresholds under the Competition Act 89 of 1998, the parties must notify the Competition Commission before implementation. The applicable filing fee depends on whether the transaction qualifies as an intermediate or large merger.
Competition Commission Filing Fees (2025/2026)
| Merger Category | Threshold | Filing Fee | Review Body |
|---|---|---|---|
| Small Merger | Below intermediate thresholds | No mandatory filing | — |
| Intermediate Merger | Combined turnover R560m+; target R80m+ | R150,000 | Competition Commission |
| Large Merger | Combined turnover R6.6bn+; target R190m+ | R500,000 | Competition Tribunal |
Note: Thresholds are based on the combined annual turnover or assets of all acquiring parties plus the target. Merger filing fees are not subject to VAT as they are government charges. The filing fee is paid by the acquirer and is typically non-refundable even if the merger is prohibited.
In addition to the filing fee, the parties must also budget for the cost of preparing the merger notification itself — typically charged by the attorneys handling the merger filing. Competition merger filings are specialist work and are generally billed separately from the main transaction legal fees. Preparation of an intermediate merger filing typically costs R50,000–R150,000 in attorney fees; a large merger filing can cost significantly more depending on complexity and whether competition economics advice is required.
The Competition Commission must be notified within 10 business days of the implementation trigger (the earliest of the parties concluding the transaction agreement). Timing of the competition filing is therefore a critical deal management issue, and the cost of the filing must be built into the transaction timeline and budget from the outset.
Tax Costs
The tax consequences of a business sale can dwarf all other transaction costs. The deal structure — share sale vs asset sale — determines which taxes apply and in what amounts. Proper tax planning before structuring the deal is essential and can save substantial amounts.
Capital Gains Tax (CGT) on Share Sales
On a share sale, the seller is subject to CGT on the gain realised (proceeds less base cost). The inclusion rate and effective tax rate depend on whether the seller is a company or an individual:
| Seller Type | Inclusion Rate | Tax Rate | Effective CGT Rate |
|---|---|---|---|
| Company | 40% | 27% (corporate) | 10.8% |
| Individual | 40% | Up to 45% (marginal) | Up to 18% |
| Trust | 80% | 45% | 36% |
Worked Example — Company Seller, Share Sale
Purchase price: R5,000,000. Base cost of shares: R1,000,000. Capital gain: R4,000,000. Inclusion (40%): R1,600,000 included in taxable income. Corporate tax at 27%: R432,000 CGT payable. This represents an effective CGT rate of 10.8% on the R4m gain.
VAT Going Concern Exemption — Asset Sales
Where a business is sold as a going concern in an asset sale (rather than a share sale), the transaction may qualify for VAT zero-rating under section 11(1)(e) of the Value-Added Tax Act 89 of 1991. This is commercially significant: a R10 million asset sale that is VAT exempt saves R1.5 million in VAT that the buyer would otherwise need to fund and recover.
For the going concern exemption to apply: (1) both seller and buyer must be registered VAT vendors; (2) the business must be sold as an income-earning activity; (3) the business must be capable of continuing as a going concern at the date of transfer; and (4) the parties must agree in writing that the sale is of a going concern at zero rate.
Common pitfalls: The exemption can be lost if the buyer is not a VAT vendor at the date of supply, if the business is not genuinely capable of operating as a going concern (e.g., key licences have not been transferred), or if the parties fail to expressly document the zero-rating agreement. SARS has successfully challenged going concern exemptions on procedural grounds. Proper tax advice before signing is essential.
Transfer Duty on Immovable Property in Asset Sales
Where the assets being sold include immovable property (land and buildings), transfer duty is payable on the value of the immovable property being transferred. Transfer duty is imposed on the buyer under the Transfer Duty Act 40 of 1949 at rates ranging from 0% (on property values up to R1,100,000) to 13% (on values above R2,500,000). Note that if VAT is payable on the property transfer (i.e., the seller is a VAT vendor selling property as part of their enterprise), transfer duty does not apply — the two taxes are mutually exclusive.
Transfer duty does not apply to share sales. This is one of the reasons buyers and sellers sometimes prefer a share sale structure — the acquisition of shares does not trigger transfer duty even if the underlying company owns immovable property.
Warranty & Indemnity Insurance
Warranty and indemnity (W&I) insurance is a specialist insurance product that covers losses arising from breaches of warranties and indemnities given in a sale and purchase agreement. It is an increasingly common feature of mid-market and large M&A transactions in South Africa and allows the seller to achieve a clean exit (with limited post-closing liability) while giving the buyer direct recourse to an insurer rather than the seller in the event of a warranty breach.
W&I Insurance Key Parameters
| Parameter | Typical Range |
|---|---|
| Minimum deal size | R50 million (enterprise value) |
| Premium | 1% – 3% of insured limit |
| Policy type | Buy-side (buyer takes policy) or sell-side |
| Policy period | 3–7 years depending on warranty type |
| Retention (excess) | 0.5%–1% of enterprise value |
Buy-side policies are taken out by the buyer and allow the buyer to claim directly from the insurer for warranty breaches without having to pursue the seller. This is the dominant structure in most transactions. Sell-side policies are taken out by the seller to cap their liability exposure, with the buyer retaining the right to claim against the seller but with the seller's losses covered by insurance.
What is covered: Breaches of business warranties (title, authority, financial statements, tax compliance, employment, material contracts, IP) and fundamental warranties (capacity, title to shares). What is typically excluded: Known risks disclosed in the disclosure schedule, forward-looking warranties, purchase price adjustments, penalties arising from fraud.
For deals below R50 million, W&I insurance is generally not commercially viable due to minimum premium thresholds. Buyers on smaller deals must rely on contractual warranties, escrow arrangements, or deferred consideration as their protection against warranty breaches.
Two Worked Scenarios
The following scenarios illustrate how total transaction costs aggregate across a small SME deal and a large corporate transaction requiring Competition Commission approval.
Scenario A: R8m SME Asset Sale
Small owner-managed business, asset sale structure, going concern VAT exemption applies
| Cost Item | Estimate (excl. VAT) |
|---|---|
| Seller's attorney fees | R25,000 |
| Buyer's attorney fees | R20,000 |
| Financial due diligence | R30,000 |
| Tax advice (structure + going concern) | R15,000 |
| CGT on seller's gain (estimate) | R130,000 – R400,000 |
| Competition filing | N/A |
| Transfer duty (no immovable property) | N/A |
| Total Transaction Costs (excl. CGT) | ~R90,000 |
Transaction costs (excluding CGT and seller's tax liability) represent approximately 1.1% of the R8m purchase price. CGT on the seller's gain is the dominant cost and depends entirely on the seller's base cost in the business.
Scenario B: R120m Share Sale with Competition Approval
Mid-market share sale, intermediate merger filing required, W&I insurance
| Cost Item | Estimate (excl. VAT) |
|---|---|
| Seller's attorney fees (incl. competition) | R350,000 |
| Buyer's attorney fees (incl. competition) | R400,000 |
| Financial due diligence | R150,000 |
| Tax due diligence | R60,000 |
| Competition Commission filing fee | R150,000 |
| W&I insurance premium (2% of R60m limit) | R1,200,000 |
| Tax structuring advice | R80,000 |
| CGT on seller's gain (estimate) | R5,000,000 – R15,000,000+ |
| Total Transaction Costs (excl. CGT) | ~R2,390,000 |
Transaction costs (excluding CGT) are approximately 2% of the R120m purchase price. The W&I insurance premium is the largest single non-tax cost. CGT on the seller's gain — assuming a low base cost — is likely to dwarf all other transaction costs and is the most important cost to model upfront.
How to Manage Costs
Business sale transaction costs are largely non-discretionary — you cannot avoid paying CGT if it is due, or skip the Competition Commission filing if you are legally required to notify. But there are meaningful steps both sellers and buyers can take to avoid unnecessary cost inflation.
Negotiate Fixed Fees with a Defined Scope
Many commercial attorneys will agree a fixed fee for a clearly scoped mandate — typically covering the initial draft of the sale agreement, one round of negotiations, and closing. Ask your attorney to provide a fixed fee covering these stages, with an agreed hourly rate for anything outside scope. This gives you budget certainty and aligns incentives for efficient drafting.
Stage Attorney Engagement
You do not need to instruct attorneys at full rate from day one. Use your attorney for high-value strategic work (agreement drafting, negotiation, closing mechanics) and handle administrative tasks (document collation, data room preparation, due diligence document index) internally or using a paralegal. Staged engagement can reduce legal fees by 20–40% on well-managed transactions.
Commission Vendor Due Diligence
On competitive sale processes or where the seller anticipates multiple buyer enquiries, commissioning vendor due diligence (a DD report prepared by the seller's accountants and made available to all bidders) reduces the overall DD cost on the deal and accelerates the timeline. Each buyer need not commission their own fresh DD — they review the vendor report and rely on it (with appropriate reliance letters). This is standard practice on larger structured sale processes.
Conduct Early Competition Assessment
Do not wait until the sale agreement is signed to assess whether a Competition Commission filing is required. Engage a competition attorney early to assess the merger notification thresholds based on the parties' combined turnover and the target's turnover. An early assessment can prevent costly surprises — including the risk of implementing a notifiable merger without approval, which carries significant penalties under the Competition Act.
Get Tax Structuring Advice Before Signing
Tax structuring advice is one of the highest-return investments in any business sale transaction. A tax advisor engaged before the term sheet is signed can identify deal structures, rollover relief provisions, and exemptions that may not be available once the transaction is committed. Post-signing tax advice can optimise the tax treatment within the agreed structure but cannot change the structure itself. Early tax engagement typically costs R15,000–R40,000 and can save multiples of that amount.
Frequently Asked Questions
What do legal fees cost for a business sale in South Africa?
Legal fees depend on the size and complexity of the deal. For small transactions below R10 million, combined legal fees (seller and buyer) typically range from R25,000 to R80,000. Medium deals between R10 million and R100 million cost R80,000 to R250,000 in legal fees. Large or complex transactions — those involving regulatory submissions, multiple closing conditions, or prolonged warranty negotiations — can cost R250,000 to R2 million or more. Attorney fees are charged on a time-and-complexity basis at rates of R2,500–R6,000 per hour, though fixed fees are available for defined scopes. All attorney fees are subject to 15% VAT.
How much does due diligence cost?
Financial due diligence conducted by auditors or accountants typically costs R30,000–R200,000 depending on the size and complexity of the target's financial records and the number of entities in the group. Legal due diligence is generally included within the buyer's attorney fees and does not attract a separate charge. Tax due diligence by a specialist tax advisor costs R20,000–R100,000 depending on the complexity of the target's tax position and compliance history. IT or technical due diligence, where commissioned separately, costs R15,000–R80,000. Virtual data room costs (where a dedicated platform is used rather than a shared drive) typically run R5,000–R30,000 per month.
What is the Competition Commission filing fee?
The Competition Commission charges R150,000 for an intermediate merger filing and R500,000 for a large merger filing. These are government charges and are not subject to VAT. The intermediate merger threshold applies where the combined annual turnover or assets of all the acquiring parties plus the target exceeds R560 million, and the target's turnover or assets exceed R80 million. The large merger threshold applies where the combined turnover exceeds R6.6 billion and the target's exceeds R190 million. The filing fee is paid by the acquiring party and is non-refundable. In addition to the filing fee, parties should budget for the cost of preparing the merger notification — typically R50,000–R150,000 in attorney fees for an intermediate merger filing.
What tax is payable on a business sale?
The tax payable depends on whether the transaction is structured as a share sale or an asset sale. On a share sale, the seller is subject to capital gains tax on the gain (proceeds less base cost). Companies have a 40% inclusion rate taxed at the 27% corporate rate, giving an effective CGT rate of 10.8%. Individuals have a 40% inclusion rate taxed at their marginal rate, giving an effective CGT rate of up to 18%. On an asset sale, VAT may apply at 15% unless the transaction qualifies for the going concern zero-rating — both parties must be VAT vendors and the business must be sold as a going concern. If immovable property is transferred in an asset sale, transfer duty applies on the property value (0%–13% depending on the value). Transfer duty does not apply to share sales.
Budget for the Full Cost Before You Sign
The most common mistake sellers and buyers make is budgeting only for attorney fees and overlooking tax, due diligence, Competition Commission costs, and W&I insurance. A comprehensive transaction cost budget — prepared before the term sheet is signed — allows both parties to negotiate with eyes open and avoids the uncomfortable situation of discovering a R5 million CGT liability after committing to a deal price.
