Selling an NDIS business is a significant financial event — and the tax outcome can vary dramatically depending on how the deal is structured, how long you've owned the business, and which concessions you're eligible for.
Most NDIS business sellers focus on the sale price. Far fewer think about what they'll actually keep after tax. That's a costly oversight. With the right advice and planning, some sellers can reduce their CGT liability substantially — in some cases, to zero. Others, without guidance, pay far more than necessary.
This article explains the core tax considerations every NDIS business seller in Australia should understand before going to market. It is not a substitute for advice from a registered tax professional — but it gives you the language and framework to have that conversation with confidence.
Capital Gains Tax and What Triggers It

When you sell an NDIS business or its assets for more than your cost base — the original purchase price plus associated costs — the profit is a capital gain. That gain forms part of your assessable income and may be subject to Capital Gains Tax (CGT).
The rate you pay depends on your business structure. Sole traders and partners in a partnership pay CGT at their marginal income tax rate. Companies pay CGT at the applicable company tax rate. Trusts distribute the gain to beneficiaries, who then pay at their own rates.
How much CGT you ultimately pay — and whether you pay any at all — depends heavily on whether you qualify for any of the small business CGT concessions administered by the Australian Taxation Office (ATO).
The Four Small Business CGT Concessions
The ATO provides four CGT concessions specifically for small businesses selling active assets. NDIS businesses — particularly the goodwill, participant agreements, and operational assets — commonly qualify as active assets. To access any of the concessions, you must first meet the basic eligibility conditions: your business must be a small business entity with an aggregated turnover under $2 million, or your net asset value (including related entities) must not exceed $6 million.
If you pass those thresholds, here are the four concessions available:
1. The 15-Year Exemption — This is the most generous concession. If you have continuously owned the active asset for at least 15 years, are aged 55 or over, and are selling in connection with your retirement (or are permanently incapacitated), the entire capital gain can be disregarded. You pay no CGT on the sale proceeds. This is the exit that long-term NDIS business owners should plan toward — the 15-year clock starts from the date you acquired the asset.
2. The 50% Active Asset Reduction — After applying capital losses and the general CGT discount (50% for individuals who have held the asset more than 12 months), this concession further reduces your remaining capital gain by 50%. It applies automatically if the basic conditions are met, unless you choose to opt out — for example, in favour of the retirement exemption.
3. The Retirement Exemption — This allows you to exclude up to a lifetime limit of $500,000 of capital gains from tax when selling active business assets. If you are under 55, the exempt amount must be contributed to a complying superannuation fund. If you are 55 or over, the payment into super is optional.
4. The Small Business Rollover — If you're planning to reinvest in another active business asset, this concession allows you to defer all or part of the capital gain for up to two years — or longer if you acquire a replacement asset within that period. This is useful for sellers who aren't exiting entirely but are restructuring their business holdings.
These concessions can be combined in a specific order, and applying them correctly requires careful tax planning. An accountant or tax adviser with experience in business sales should be involved well before settlement.
GST and the Going Concern Exemption
The other major tax consideration in an NDIS business sale is GST.
When you sell a business as an asset sale, GST can apply to the sale price — adding 10% to what the buyer is paying, or cutting into what you receive if the contract doesn't address it clearly. However, if the sale qualifies as a supply of a going concern, the transaction is GST-free under section 38-325 of A New Tax System (Goods and Services Tax) Act 1999.
To qualify, several conditions must be met: both parties must be registered for GST; there must be a written agreement stating that the sale is a supply of a going concern; the seller must supply everything necessary for the continued operation of the business; and the seller must continue operating the business up until the day of settlement.
If any of those conditions are not met, or if the ATO later determines the exemption doesn't apply, GST liability can fall on the seller. For this reason, well-drafted sale contracts typically include a clause that passes the GST risk to the buyer if the ATO rejects the going concern treatment.
In a share sale — where the buyer acquires the shares of the company that owns the NDIS business — the share transaction is generally treated as a financial supply and is input taxed, meaning GST does not apply to the sale of shares themselves.
The GST treatment is another reason why NDIS provider sale process decisions — asset sale versus entity acquisition — should be made with legal and tax advice, not just based on what's simplest.
How Deal Structure Affects Your Tax Position
The choice between an asset sale and a share sale (entity acquisition) affects both CGT and GST outcomes.
In an asset sale, the seller triggers a CGT event on the individual assets sold — goodwill, client lists, equipment, and so on. Each asset has its own cost base and may be treated differently. Active assets qualify for the small business CGT concessions. However, goodwill is typically a significant driver of value in an NDIS business sale, and it is generally an active asset eligible for those concessions.
In a share sale, the seller disposes of their shares in the company, and CGT applies to the gain on those shares. Depending on the structure, the small business CGT concessions may still apply — but the rules are more complex and require careful analysis against the eligibility conditions.
Sellers should not assume that the structure preferred by a buyer automatically works in their favour from a tax perspective. Your preferred deal structure may be different from the buyer's, and negotiating this requires understanding the tax consequences on both sides.
Plan Early: Tax Outcomes Are Shaped Before the Sale
The single most important piece of advice for NDIS business sellers is this: talk to your accountant or tax adviser before you list, not after you receive an offer.
Several of the most valuable concessions — particularly the 15-year exemption — depend on conditions that have been building over years. Once you decide to sell, it is too late to change those conditions. Sellers who plan their exit with a three-to-five year horizon can often structure their affairs to maximise eligibility for concessions, time the sale appropriately relative to their age, and minimise the gap between the headline sale price and what they actually bank.
Working with NDIS business brokers who understand this landscape means your sale timeline and deal structure can be considered alongside your tax position — rather than creating tax surprises at settlement.
