When you sell a business, the tax outcome depends on what you’re selling and how the deal is structured. An asset sale (selling the business’ assets like goodwill, equipment and stock) often triggers different taxes than a share or unit sale (selling your interest in a company or trust). Broadly, gains on capital assets (goodwill, intellectual property, freehold property) are subject to capital gains tax (CGT). Plant and equipment are depreciating assets: profits or losses on disposal are usually handled via a “balancing adjustment” under depreciation rules rather than CGT. Trading stock is ordinary income to the seller (and deductible to the buyer). Keeping these buckets separate is essential because each has its own rate, concessions and record requirements. If you’re weighing up an asset sale versus a share sale, the choice can materially change GST, CGT concessions, duty and even your ability to contribute sale proceeds to super. A Toowoomba Financial Adviser can model each pathway so your after-tax proceeds fit your household goals as well as your exit timing.

Tax Implications of Selling a Business

CGT basics: timing, method and discount

For capital assets, the most common CGT event is CGT event A1 (disposal). Critically, the CGT happens on the contract date, not settlement, which affects which financial year the gain lands in and whether the 12-month holding period for discounts is met. Individuals and trusts may be eligible for the 50% general CGT discount on assets held for at least 12 months; companies can’t access that discount. Accurate contract dating, completion timetables and records (including cost base adjustments) are therefore essential to avoid surprises. If you’re selling near 30 June, the contract date can shift your tax year entirely. Your Online Financial Adviser can help you plan instalments, prepayments and super strategies around the expected tax year of the gain.

GST: when the sale can be GST-free as a “going concern”

Many business sales are structured as the supply of a going concern, which can be GST-free if strict conditions are met. In short: the sale must be for consideration; the purchaser must be (or be required to be) registered for GST; the parties must agree in writing that the supply is of a going concern; and the seller must supply all things necessary for the continued operation and carry on the enterprise until completion. Get this wrong and GST may apply to parts of the sale (e.g., stock, equipment), changing cash flows at settlement. Best practice is to bake the going concern wording into the contract and ensure the buyer’s GST registration is confirmed before exchange. Your adviser and lawyer should also consider apportionments, adjustments and settlement statements to avoid later disputes.

Queensland duty: transfer duty and landholder duty traps

In Queensland, transfer duty (stamp duty) can apply to an asset sale of a Queensland business—especially on goodwill and intellectual property—even when no land is involved. If the target holds land in Queensland, landholder duty can apply on a share or unit sale when the entity’s Queensland landholdings meet thresholds and the buyer acquires a “significant interest” (commonly 50% for private companies), with calculations linked to the value of the underlying land. These state taxes materially affect net proceeds and deal structure. Early scoping with your deal team avoids “duty shock” late in negotiations and helps you weigh an asset vs share sale with proper state tax costs in view.

The small business CGT concessions: four powerful tools

If you meet the basic conditions, Australia offers four small business CGT concessions that can reduce or even eliminate the tax on selling active business assets:

15-year exemption – full CGT exemption if you’ve owned the asset for 15+ years and meet age/retirement or incapacity criteria.
50% active asset reduction – halves the remaining gain on active assets.
Retirement exemption – disregard up to $500,000 of gains per individual (with super contribution requirements if under 55).
Small business roll-over – defer part or all of a gain if you acquire replacement active assets or improve existing ones within set timeframes.

These concessions sit on top of the general 50% discount (for individuals/trusts) if eligible, and can be combined in a prescribed order. Getting eligibility right—before you sign—is mission-critical.

Who qualifies: key eligibility tests (turnover, assets, and share/unit conditions)

To access the concessions you must satisfy the basic conditions, typically by being a small business entity (aggregated turnover < $2m) or passing the $6m maximum net asset value test, and selling an active asset. If you’re selling shares or trust units, extra conditions apply—often involving the significant individual test, where someone has at least a 20% small business participation percentage (direct or indirect). These rules are technical and interact with connected/affiliated entities, so ownership charts and look-throughs matter. Map your structure early and confirm who your “significant individuals” are before offers go out; small tweaks in holdings or timing can make or break eligibility.

How the concessions stack (and why order matters)

In broad terms, you apply capital losses first, then (if eligible) the 50% general CGT discount (individuals/trusts), then the 50% active asset reduction (which applies automatically unless you elect out), and finally the retirement exemption and/or roll-over to the remaining amount. The order is crucial because it determines how much you can push into super under the concessions, how much is deferred, and how much tax is crystallised. There are cases where you might choose not to apply the active asset reduction to maximise tax-free payments via the retirement exemption. A Financial Planning Toowoomba specialist can run the numbers to find the optimal sequence for your situation and age.

Superannuation strategies: using the CGT small business caps

Two concession pathways can turbo-charge your super. Under the 15-year exemption, you may be able to contribute sale proceeds to super without counting against non-concessional caps, up to the CGT cap amount (indexed). Under the retirement exemption, up to $500,000 per individual (lifetime) can be contributed under the CGT cap rules. For 2025–26, industry technical briefings put the CGT cap at $1.865m. These contributions are separate from standard caps (e.g., the general concessional cap is $30,000 from 1 July 2024) and can apply even if your total super balance exceeds the general transfer balance cap. Precise paperwork (CGT cap elections) and timing are vital. Aligning your exit with your Retirement Financial Advice plan helps convert business value into long-term, tax-effective wealth.

Depreciating assets and trading stock: not CGT (mostly)

When you sell depreciating assets (machinery, vehicles, fit-out), a balancing adjustment compares termination value to written-down value: the excess is assessable income (or a deduction if less), rather than a capital gain. CGT is generally disregarded for business-use depreciating assets. If assets had private use, CGT event K7 may arise to the private-use extent. Trading stock is ordinary income at disposal; GST may apply unless the sale qualifies as a GST-free going concern. These mechanics often justify separate line-item pricing in the contract for stock, plant and goodwill—because the tax treatment differs for each bucket. Clean fixed asset registers and stock counts save tax time angst.

Earn-outs and vendor terms: how later payments are taxed

If part of your price depends on future performance (an earn-out), Australia uses “look-through” CGT treatment for qualifying look-through earnout rights. Rather than guessing the value upfront, later payments adjust the capital proceeds (for sellers) or the cost base (for buyers) when they’re received. Qualifying earn-outs must meet specific criteria, including that financial benefits are linked to economic performance and generally provided within five years after the end of the income year in which the CGT event occurred. Get your lawyers and tax adviser to draft earn-out clauses that meet the tests—poor drafting can deny the concession and trigger messy amendments.

Foreign resident CGT withholding: clearance certificates and new settings

Where taxable Australian property (for example, real property used in the business) is sold, the purchaser may need to withhold and remit foreign resident capital gains withholding (FRCGW) unless the vendor provides a clearance certificate. From 1 January 2025, the withholding rate increased to 15% and the $750,000 threshold was removed, meaning more transactions require certificates to avoid withholding—even at lower prices. If your sale includes land or long leases, build FRCGW checks into your deal checklist early so settlement funds aren’t clipped unexpectedly.

Asset sale vs share sale: practical tax differences

In an asset sale, the seller recognises income on stock, balancing adjustments on plant, and CGT on capital assets like goodwill. GST and Queensland transfer duty can apply, but small business CGT concessions may be available at the owner level. In a share (or unit) sale, there’s no GST on the share transfer, and the seller typically faces CGT on the shares—again with potential access to concessions if “significant individual” and active-asset conditions are met for shares/units. However, if the company or trust holds Queensland land, landholder duty can apply on the equity transfer. Buyers often favour asset deals for step-ups and risk control; sellers often prefer share deals for simpler tax and clean exit. Your Toowoomba Financial Adviser can help weigh price vs after-tax proceeds to choose the structure that best serves your goals.

Price allocation, records and “evidence beats guesswork”

ATO scrutiny increases when sale prices are lump-sum with no sensible allocation. A commercially supportable allocation across goodwill, plant and equipment, and stock reflects economic reality and aligns with each asset’s tax rules. For goodwill specifically, ATO guidance sets out how goodwill is treated under CGT events—so keep valuation files, contract schedules, and working papers tidy. Attach invoices, settlement statements and valuation reports to your accounting file. Well-organised documentation not only reduces disputes at tax time, it also protects your access to the small business concessions by proving use, ownership periods and active-asset status.

Deal timeline: a 6–18 month roadmap for sellers

6–12 months out: Clean financials, reconcile fixed asset registers, verify share/unit registers, map connected entities and confirm who your significant individuals are. 3–6 months out: Model asset vs share sale, test eligibility for concessions, line up super strategies and CGT-cap paperwork, and agree a price allocation approach. Contract stage: Lock down going concern wording (if relevant), confirm buyer’s GST registration, address FRCGW clearance, and plan settlement statements. Pre-settlement: Prepare BAS/GST adjustments, stocktake and final debtor/creditor cut-offs. Post-settlement: Execute super contributions under the 15-year or retirement exemptions within timeframes, finalise tax elections, and store all documents securely. Working to a rhythm with a Financial Planning Toowoomba specialist keeps the transaction orderly and tax-efficient, without frantic last-minute fixes.

Owner wealth: turning sale proceeds into a retirement plan

Your business exit is also a household money moment. Decide how much to direct to superannuation under the CGT concessions, how much to park in offset/redraw, and how much to invest for income. The timing of super contributions (and the choice of fund options) should align with your investment horizon and risk profile, not just tax. Consider insurance run-off, personal emergency buffers, and a staged income plan so life after the sale is calm and fully funded. A tailored plan with an Online Financial Adviser ensures concession-driven contributions integrate with your broader Retirement Financial Advice strategy—so the tax win turns into lasting wealth.

Common mistakes (and quick fixes)

Signing before testing eligibility: Run the small business CGT concession tests (including significant individual look-throughs) before issuing heads of agreement.
Forgetting contract date rules: Remember CGT is pegged to the contract date, not settlement; plan cash and instalments accordingly.
Sloppy going concern wording: Put the GST-free “going concern” agreement in writing within the contract.
Ignoring Queensland duty: Asset deals can trigger transfer duty; share/unit deals can trigger landholder duty if land is involved. Budget for it.
Earn-out clauses that miss the rules: Draft to satisfy look-through earnout criteria or risk re-assessments later.

Local lens: Toowoomba considerations

In and around Toowoomba, many sales include plant-heavy trades, ag-adjacent enterprises, and premises with land or long leases—each with distinct tax consequences. Seasonality (harvest or school-holiday impacts) can influence completion dates and therefore the contract timing of the CGT event. Queensland’s transfer duty on business assets and landholder duty on equity sales with QLD land mean structuring needs a local lens. If you’re relocating or semi-retiring after the sale, line up super contributions and cash flow plans well before settlement so your household stays liquid while tax paperwork is finalised. A Toowoomba Financial Adviser can coordinate the tax, duty and super levers into one coherent exit plan.

Quick reference: which taxes touch which assets?

Goodwill/IP: CGT (discount/concessions may apply).
Plant & equipment: Depreciation balancing adjustment (income or deduction); CGT generally disregarded for business-use assets.
Trading stock: Ordinary income to seller.
Commercial property: CGT; GST unless going concern; duty on transfer; landholder duty possible on share/unit deals.
Shares/units in trading entity: CGT; no GST on the equity transfer; small business concessions may apply if additional tests are met.

Final word

Selling a business is as much about design as it is about price. The right mix of structure, timing, and concessions can transform your after-tax outcome and super balance. Before you sign, map your eligibility, confirm GST and duty positions, and decide how the proceeds feed your Financial Planning Toowoomba strategy. If you’d like a model of your options (asset vs share sale, concession sequencing, and super contributions), we can build that and help you execute with confidence.
