Tax Structuring When Selling a Business in Australia: CGT Concessions Explained

For most owners, the sale price is only half the story. The other half is what you keep after tax. In Australia, the small business CGT concessions (Division 152) can reduce capital gains dramatically—sometimes to zero. But they’re not automatic. The outcome depends on how the deal is structured, how your business is held (company, trust, individual), and whether you satisfy several technical tests that can be tripped up by things as mundane as a large cash balance, an intercompany loan, or a passive investment property held in the same entity.

This article is a practical, seller-focused guide to tax structuring for business sales—specifically the CGT concessions—so you can ask better questions early, avoid common traps, and build a transaction plan that doesn’t fall apart when your accountant and the buyer’s lawyer finally look under the hood.

Important: This is general information only, not tax advice. The CGT concessions are highly fact-specific. Always obtain advice from your tax advisor before taking action.

What Are the Small Business CGT Concessions (Division 152)?

The small business CGT concessions are a set of rules that can reduce or eliminate capital gains made on the sale of certain business assets (including shares or trust interests in an “active” business). The four concessions work like a toolkit:

1. 15-year exemption (can eliminate the gain completely, if strict conditions are met)
2. 50% active asset reduction (halves the gain, subject to eligibility)
3. Retirement exemption (can disregard up to $500,000 of gain per individual over their lifetime, with conditions)
4. Small business rollover (defers the gain, subject to replacement asset rules)

These concessions can apply to:

• Shares in a company you own (if the company is a qualifying “CGT small business entity” and other tests are met)
• Units / interests in a trust that carries on the business
• Business assets sold in an asset sale (goodwill, plant & equipment, intellectual property, etc.)

Why “Tax Structuring” Matters Before You Go to Market

Owners often engage brokers/advisors, run a process, negotiate commercial terms—and only then discover that the tax outcome is materially worse than expected. This usually happens for one of three reasons:

• The deal structure (share sale vs asset sale) doesn’t match the seller’s tax plan
• The business doesn’t satisfy the eligibility tests (or only some stakeholders do)
• The entity structure (holding company, family trust, related entities) creates unexpected “connected entity” or “affiliate” issues

Good structuring starts early—ideally 12–24 months before exit—because some fixes require time (e.g., cleaning up passive assets, restructuring, clarifying ownership and control, improving documentation).

The Core Eligibility Tests (In Plain English)

To access Division 152 concessions, you generally need to satisfy:

1) The “Small Business” Test (Turnover or Net Assets)

Broadly, you need to satisfy either:

• Aggregated turnover test (commonly referenced as under $2m, noting thresholds can change and nuances apply), or
• Maximum net asset value (MNAV) test (commonly referenced as under $6m for the net value of CGT assets, including connected entities and affiliates).

The “gotcha” is the word aggregated. You don’t just look at the business you’re selling. You may need to include related entities (connected entities and affiliates), which can pull in other businesses, trusts, and investments.

2) The Active Asset Test

The asset being sold (or the underlying business assets, in the case of shares) generally needs to be an active asset. In simple terms: it must be used (or held ready for use) in carrying on a business for a required portion of the ownership period.

Common risks:

• Passive assets sitting in the trading entity (e.g., investment properties, large investment portfolios)
• Excess cash and loans to related parties that are not genuinely required for the business
• “Business” property that is actually used mainly to derive rent (e.g., a property-leasing entity)

3) Ownership / Stakeholder Tests (Significant Individual & CGT Concession Stakeholders)

When the sale is of shares (company) or units (trust), Division 152 introduces additional ownership concepts such as a significant individual and CGT concession stakeholders. The practical point is:

• The ATO cares not just about the business, but who economically benefits from the sale.
• Distributions from a trust, different share classes, unpaid present entitlements (UPEs), and family arrangements can all complicate this.

If you’re operating through a trust (very common in Australia), this is where careful advice is essential. A late-stage change to beneficiaries or distribution patterns can create unexpected outcomes.

Share Sale vs Asset Sale: The Tax Structuring Decision That Drives Everything

Most transactions come down to one of two legal structures:

Option A: Share sale (seller sells shares in the company)

Typical seller preference: Share sales often produce cleaner outcomes for the seller because the gain is on shares, and it may be more likely (depending on facts) that CGT concessions apply at the shareholder level.

Typical buyer concern: In a share sale, the buyer inherits the company’s history (tax, legal, employee, warranty claims). Buyers may demand extensive warranties/indemnities or a price discount for risk.

Option B: Asset sale (company sells assets; seller then extracts cash)

Typical buyer preference: Buyers like asset sales because they pick the assets they want and avoid liabilities they don’t.

Typical seller problem: Asset sales can create two layers of tax in a company structure—tax on the asset sale, then tax when extracting funds (dividends). CGT concessions might apply to some assets (e.g., goodwill) but not others, and the extraction planning matters.

Reality: Many deals end up as an asset sale for buyer risk reasons. That doesn’t mean you can’t plan for it—but you need to model it early so you don’t accept a headline price that is effectively “net of tax” once the structure changes.

How the Four CGT Concessions Work (Practical Overview)

1) The 15-Year Exemption (The “Gold Standard”)

If you qualify, the 15-year exemption can disregard the entire capital gain on the sale of the asset (including shares). It is powerful, but conditions are strict. Common features typically include:

• Continuous ownership for at least 15 years (with certain continuity rules)
• The taxpayer (or relevant individual) is at least 55 and retiring, or is permanently incapacitated
• The business satisfies the basic eligibility conditions (small business / MNAV, active asset)

Structuring insight: If you are close to 15 years, or close to age thresholds/retirement triggers, timing the transaction and documenting “retirement” properly can be valuable. Don’t assume “I’m slowing down” automatically satisfies the test.

2) The 50% Active Asset Reduction

This concession generally reduces the capital gain by 50% (after applying any general CGT discount where applicable). It’s often a stepping stone that can then be combined with:

• the retirement exemption, and/or
• the rollover.

Structuring insight: The order of concessions and interaction with the general CGT discount matters. Your advisor should model the sequence, especially where multiple stakeholders share the gain.

3) The Retirement Exemption (Up to $500k per Person)

The retirement exemption can disregard up to $500,000 of capital gains per individual over their lifetime. If you’re under a certain age at the time of choosing the exemption, amounts may need to be contributed to superannuation. The rules are technical, but the practical implications are clear:

• It can be a major tax lever for owner-operators, especially couples with ownership split appropriately.
• It requires careful stakeholder identification and documentation.

Structuring insight: Ownership percentages (and who is a concession stakeholder) can change the total retirement exemption capacity available across the family group. Fixing ownership late can be difficult and may have separate tax consequences—so plan early.

4) The Small Business Rollover (Deferral)

The rollover can defer the capital gain if you acquire a replacement asset or make certain investments within relevant time windows. It’s commonly used when:

• You’re selling one business and buying another
• You need time to decide on reinvestment
• You want to manage taxable income across years (subject to advice)

Structuring insight: Rollover is not “free tax”; it is usually a deferral with conditions. Ensure you understand what triggers the deferred gain later.

Common Deal Terms That Affect CGT Outcomes (And Surprise Sellers)

Earnouts and Deferred Consideration

When part of the price is paid later (earnout, vendor loan, deferred instalments), the CGT timing and valuation can become complex. For sellers relying on concessions, the question becomes: when is the capital gain made, and on what value?

Seller takeaway: Don’t negotiate earnout mechanics purely as “commercial upside.” Model the after-tax outcome and ensure the legal drafting aligns with your tax position.

Working Capital Adjustments and Completion Accounts

Sale proceeds can move post-completion due to completion accounts. This can affect the final gain. Ensure your advisors communicate so the accounting mechanism doesn’t accidentally undermine the tax modelling.

Restraint of Trade Allocations

Some deals allocate part of consideration to restraints of trade or employment/consulting arrangements. This can shift amounts from capital to revenue treatment (or create other consequences). Buyers sometimes prefer this for their own tax deductions; sellers may dislike it if it increases assessable income.

Seller takeaway: Push for clarity on allocations and ensure you understand the tax character of each component of the price.

Pre-Sale “Tax Readiness” Checklist (12 Months Before Exit)

These are practical steps that often improve the likelihood of achieving the intended CGT concession outcome:

1) Map the Group Structure (Entities, Owners, Control)

• List all entities: trading company, trusts, holding companies, property entities
• Identify controllers, directors, trustees, appointors
• Confirm share classes, unit holdings, and beneficiary arrangements

2) Identify Passive Assets and “Non-Business” Items

• Investment properties held in the trading entity
• Large surplus cash not required for operations
• Intercompany loans and related-party receivables
• Unused assets and legacy items on the balance sheet

Why it matters: These items can impact active asset status and MNAV calculations, and they can complicate sale negotiations (buyers may demand they’re carved out anyway).

3) Clean Up Documentation (So Due Diligence Doesn’t Drive a Structure Change)

• Employment agreements and contractor arrangements
• Customer/supplier contracts and assignability
• IP ownership and licensing
• Leases and consents

Transaction reality: If the buyer finds problems late, they may insist on an asset sale instead of a share sale. Tax readiness and legal readiness are connected.

4) Model Outcomes Under Both Deal Structures

At a minimum, you want a model showing:

• Share sale: expected CGT, availability of concessions, and cash to owners
• Asset sale: company-level tax, extraction strategy, and net cash to owners
• Impact of earnouts and deferred payments

5) Consider Whether Restructuring Is Needed (But Don’t DIY It)

Sometimes restructuring is worthwhile (e.g., separating passive assets from the trading entity). But restructuring can itself trigger tax, duty, and “integrity” issues. It must be planned carefully and early.

Worked Example (Conceptual)

Consider a business owner selling their trading company for $4.0m. The company holds:

• $2.8m of goodwill and business value
• $700k of plant and equipment
• $500k of surplus cash and an investment portfolio

Scenario 1: Buyer agrees to a share sale. The seller’s gain is on the shares. If Division 152 applies (and stakeholder tests are satisfied), the seller may reduce the gain significantly via concessions.

Scenario 2: Buyer insists on an asset sale. The company sells goodwill and assets, potentially triggering tax in the company. Then the owner needs to extract cash (dividends), potentially creating another tax layer. In addition, the buyer will often demand the surplus cash and investments are removed prior to completion, which changes both the price and the tax base.

Lesson: The “same” headline price can produce very different net outcomes depending on structure and balance sheet composition. This is why tax structuring is not a last-minute checkbox—it’s a core part of exit strategy.

Common Traps That Break CGT Concession Eligibility

Trap 1: You Assume You’re “Small” Without Testing Aggregated Turnover / Net Assets

Owners often look at trading revenue alone and conclude they qualify. But aggregated tests can include other entities, and MNAV can include assets you forgot existed.

Trap 2: Passive Assets in the Trading Entity

Holding investment assets in the same entity as the trading business may create active asset test issues and complicate buyer negotiations. Often, buyers require these assets to be carved out anyway.

Trap 3: Ownership and Trust Distributions Don’t Match “Stakeholder” Requirements

Where the business is held in a discretionary trust, the pattern of distributions, documentation, and beneficiary entitlements can matter. This is not an area to “wing it” late in the process.

Trap 4: You Leave It Too Late to Document Retirement / Exit Intent

If you want to rely on the 15-year exemption, the retirement aspects must be supported by facts and evidence. The deal documents, your role post-sale, and your ongoing involvement can all be relevant.

Key Takeaways

• Division 152 CGT concessions can materially change what you keep after selling. But eligibility is technical and must be confirmed early.
• Share sale vs asset sale is the structuring decision that drives the tax outcome. Model both structures before you go to market.
• Passive assets, surplus cash, and related-party loans can create eligibility issues and negotiation friction.
• Trust and ownership structures can affect who qualifies as a stakeholder and how much of the gain can be disregarded.
• Start 12–24 months early where possible—some fixes require time and careful restructuring advice.

Final Thoughts

In a business sale, tax is not just an accounting issue—it’s a deal issue. A well-run exit process aligns commercial terms, legal structure, and tax outcomes so you don’t end up renegotiating the transaction (or accepting a worse offer) because the after-tax result surprises you late.

If you’re planning to sell within the next 6–24 months, the best first move is a structured “exit readiness” review: entity map, concession eligibility scan, and a share sale vs asset sale model. That gives you negotiating leverage and a clearer target price—because you understand what you’re actually keeping.
