Earn-Outs and Deferred Consideration in NDIS Business Sales: What Buyers and Sellers Need to Know

Not every NDIS business sale settles with a single cheque on a single day. When a buyer and seller can't agree on what a business is worth right now, a deferred payment structure — most commonly an earn-out — can bridge that gap and get the deal done.

Used well, these structures are a legitimate and practical tool. Used poorly, they create disputes, delay payments, and occasionally end in litigation. Here's what both sides need to understand before agreeing to one.

What's the Difference Between an Earn-Out and Deferred Consideration?

They're related but not the same thing.

Deferred consideration is a fixed portion of the purchase price that's paid after settlement on an agreed schedule, usually over 12 to 24 months. The amount is set; only the timing is delayed.

An earn-out links part of the purchase price to future business performance. The seller only receives those additional payments if the business hits agreed targets — revenue, EBITDA, participant numbers, or another metric — after the sale completes.

Both are common in Australian SME transactions, particularly where a buyer wants to reduce the risk of overpaying and a seller believes the business is worth more than the buyer's upfront offer reflects.

Why Earn-Outs Come Up in NDIS Business Sales Specifically

NDIS businesses present a particular valuation challenge for buyers.

Revenue is recurring and government-funded, which looks attractive. But it's also tied to individual participants, their plans, and their right to choose their own provider at any time. A participant can disengage regardless of what any contract says, because self-determination is a core NDIS principle.

That creates a genuine uncertainty gap between what a seller believes their business is worth (based on current participant numbers and billing) and what a buyer is willing to pay upfront without knowing how many of those participants will still be there in 12 months.

An earn-out based on participant retention or sustained revenue is a logical way to split that risk between both parties. Understanding how NDIS business valuation works makes those conversations far more productive.

What Metrics Work and What to Avoid

Choosing the right earn-out metric matters enormously, and this is where NDIS-specific advice is essential.

Revenue-based targets are the most common starting point. They're straightforward to measure and hard for the buyer to manipulate after settlement. The risk for sellers is that a buyer who deprioritises participant acquisition or allows service quality to slip can erode revenue without technically breaching the agreement.

EBITDA-based targets are more meaningful as a measure of business health, but they're vulnerable to the buyer's cost decisions after settlement — increased overheads, management fees, or restructuring can reduce EBITDA even if the underlying business performs well.

Participant retention targets are intuitive in an NDIS context but require careful drafting. Participants cannot be contractually required to remain with a provider, so retention needs to be defined clearly — for example, as the percentage of active participants at settlement who continue receiving services 12 months later, with a carve-out for exits caused by changed circumstances beyond the business's control.

What to avoid: vague definitions, targets that rely on the buyer's internal accounting policies, or metrics that give the buyer effective control over whether the earn-out is reached.

Protections Every NDIS Seller Should Negotiate

If you're accepting deferred consideration or an earn-out as part of your sale, these protections are not optional:

• Non-interference clause: the buyer cannot redirect participants, restructure the service model, or merge the business into another entity during the earn-out period without triggering full payment
• Reporting rights: regular financial reporting (at minimum quarterly) and the right to independently audit figures if you dispute them
• Acceleration provision: if the buyer sells the business again before the earn-out period expires, the full outstanding amount becomes immediately payable
• Dispute resolution mechanism: independent accountant determination is the standard in Australian deals and is faster and cheaper than litigation

These provisions are regularly left out of first draft agreements. Put them back in.

The ATO's CGT Treatment of Earn-Outs

This is an area where professional tax advice is essential, and the rules are specific.

Under Australian tax law, earn-out arrangements that qualify as "look-through earnout rights" receive deferred CGT treatment — meaning the seller's capital gain on each earn-out payment is assessed when the payment is actually received, not at the time of sale. This can be a significant advantage, particularly for sellers who would otherwise have a large CGT liability in the year of settlement.

To qualify for look-through treatment, the earn-out must relate to the disposal of an active asset, the maximum earn-out period cannot exceed five years from the end of the income year of sale, and the arrangement must be genuinely contingent on future performance rather than a fixed deferred payment.

The ATO has detailed guidance on this at ato.gov.au. Get a tax adviser who understands how the earn-out rules interact with the small business CGT concessions before you agree to any structure.

A Quick Word for Buyers

Earn-outs work both ways. For a buyer, they reduce the risk of overpaying for a business whose value depends on participant relationships you haven't yet tested. But they also create ongoing obligations — reporting, non-interference, and the possibility of a larger total payment if the business outperforms.

Make sure the metrics are genuinely measurable, that the accounting treatment is locked in at settlement, and that you have legal advice on your obligations during the earn-out period before you sign. A disciplined due diligence process is what makes those metrics reliable in the first place.
