Exiting a business partnership in Australia means one of three things: buying out your partner, selling your share to a third party, or winding up the business entirely. Which path is right depends on your legal structure, what’s in your agreement, and whether your partner agrees. Most partnership exits take three to six months when both parties cooperate; they can take years when they don’t.
Here’s how it actually works.
”Business Partner” Can Mean Two Different Things in Australia
This sounds pedantic, but it matters when you want out. In Australia, a formal “business partnership” is a specific legal structure — a general partnership registered under your state’s Partnership Act. If you operate as one, leaving is governed by that legislation.
But most people who say “I have a business partner” don’t actually run a formal partnership. They co-own a Pty Ltd company — as co-directors and co-shareholders. The exit process is different, the documentation is different, and the legislation that governs any dispute is different.
If you’re unsure which structure you’re in: check your ABN registration on the ABN Lookup website. If the entity type says “Partnership”, you’re in a legal partnership. If it says “Australian Private Company”, you own shares in a company — and it’s your company’s constitution and shareholders agreement that govern your exit, not partnership law.
The principles below apply to both situations. The specific formal steps differ.
Start With Your Partnership Agreement or Shareholders Agreement
Before you do anything — including having a difficult conversation with your business partner — find the document. A properly drafted partnership agreement or shareholders agreement will contain:
- An exit clause — the process for leaving voluntarily, including notice requirements
- A buyout mechanism — how the purchase price is calculated, usually referencing an independent valuation or a pre-agreed formula
- A right of first refusal — your partner typically gets first option to buy your share before you can offer it to an outside party
- Deadlock provisions — what happens when you can’t agree (important for 50/50 structures)
- A restraint of trade clause — restrictions on what you can do after you leave, particularly around competing with the business
Most Australian SME owners drafted their agreement years ago and haven’t looked at it since. I worked with a client last year who had a 40% share in a well-performing $4M revenue business. His shareholders agreement required any exiting shareholder to offer their shares at net asset value — a figure around $180,000. The market value of his 40% stake, based on a proper valuation, was closer to $700,000. The agreement was binding. (You can imagine how that conversation went when he finally read it.)
If you don’t have a written agreement — and a surprising number of Australian business partnerships don’t — you’re operating under the default rules of your state’s legislation. Those default rules may or may not reflect what you’d actually want.
The Four Ways to Exit a Business Partnership
There are four realistic exits, regardless of your structure:
1. Your partner buys your share. The most common outcome and usually the cleanest. You agree on a price for your equity, sign the transfer documents, and leave. The business continues unchanged. The key question is the valuation — more on this below.
2. You buy your partner out. The reverse. If you want to keep the business and your co-owner wants out, you buy their share. Same valuation principles apply; same need for an independent view on the number.
3. You both sell to a third party. Sometimes the cleanest outcome when neither partner wants to continue, or when neither can afford to buy the other out. A trade buyer or investor acquires the whole business at market value. For a guide to that process, see how to value your business for sale.
4. Wind up the business entirely. If the business isn’t saleable and both partners want out, the partnership dissolves: debts are paid, assets distributed, registrations cancelled. This destroys the going-concern value — the premium a buyer pays for an operating business — and is usually the last resort. Most partnership exits in Australia end in a buyout, not a wind-up.
How Your Share Is Priced: Getting the Number Right
This is where most partnership exits go wrong. It’s the number that causes the fight, and it’s the number most people get wrong before they get advice.
Your share of the business is worth a percentage of the business’s market value — not the accounting value, not net asset value, and not what either of you thinks it should be worth. The market value of an ongoing SME is typically calculated on a multiple of normalised earnings (EBITDA), adjusted for the specific characteristics of the business: profitability trend, customer concentration, staff dependency, and owner reliance.
As a benchmark: a well-run Australian SME with $500,000 in normalised annual profit might be worth $2M–$2.5M — a 4x–5x EBITDA multiple. If you own 50%, your share is worth $1M–$1.25M at market value. If your agreement says valuation at “net assets” — perhaps $200,000 total — you can see why these conversations become contentious.
One thing that regularly surprises exiting partners: a minority shareholding (less than 50%) is typically valued at a discount to the pro-rata business value, because minority shareholders have less control over distributions and business decisions. How much of a discount depends on the specific shareholders agreement and whether it contains drag-along and tag-along rights.
Getting an independent business valuation from a qualified advisor before negotiating is not optional — it’s the anchor point for the entire discussion. For context on how different methods work, see our guide on small business valuation methods in Australia.
The Formal Process for Dissolving a Partnership in Australia
If you operate as a formal legal partnership, the process for a partner leaving or the partnership dissolving is:
Step 1: Give written notice. A partner in an indefinite partnership can leave by giving written notice to all other partners. The partnership technically dissolves at the date of notice unless the agreement provides otherwise.
Step 2: Wind up partnership affairs. Existing contracts need to be fulfilled, transferred, or novated. No new business should be entered into once dissolution is triggered.
Step 3: Settle debts and distribute assets. Partnership debts are paid first; the remainder is distributed according to each partner’s interest under the agreement or applicable legislation.
Step 4: Notify the ATO. Cancel the partnership ABN, finalise the final partnership tax return, and cancel GST registration. This is mandatory, not optional.
Step 5: Deregister the business name. Cancel the business name registration with ASIC if it’s registered to the partnership.
Step 6: Notify banks, suppliers, and clients. Practically critical and often neglected until problems emerge. Your bank will need to update authority on accounts; key clients may need formal notification of the change.
For a company structure where co-shareholders are separating, the process involves formal share transfers or a share buyback, ASIC notifications (change of directors, change of shareholders), and potentially changes to the company constitution.
What Happens to Employees
Employees don’t automatically lose their jobs when a partnership changes structure — but there are obligations to manage. If the business is being wound up entirely, redundancy entitlements apply and must be properly calculated and paid. If the business continues under one partner, employment is typically transferred on the same terms. For a full breakdown, see what happens to employees when you sell a business.
The mistake is leaving employee conversations to the end. Staff often sense when something is happening before you’ve told them anything, and uncertainty kills retention.
Tax When Exiting a Partnership
The tax treatment of a partnership exit depends on your structure, the value of your interest, and how long you’ve held it.
For a company share transfer, capital gains tax (CGT) applies to the difference between your sale proceeds and your cost base. If you’ve held the shares for more than 12 months, the 50% CGT discount applies for individuals and trusts.
Australia’s small business CGT concessions may also apply — the 15-year exemption, active asset reduction, retirement exemption, and rollover provisions can significantly reduce or eliminate your liability if you meet the eligibility criteria. The difference between a structured and unstructured exit can be hundreds of thousands of dollars in tax. Read more in our guide on tax on selling a business in Australia.
One thing to avoid: entering a valuation negotiation before understanding your tax position. The after-tax proceeds — not the headline price — are what you actually keep.
When Partnership Exits Turn Adversarial
A broker I know described a 50/50 partnership in a Perth-based building services business where neither partner could agree on what the business was worth. One wanted to sell to a third party; the other refused and believed the business would be worth considerably more in three years if they kept growing. Eighteen months of deadlock followed. Legal fees north of $80,000. Two key site managers left during the uncertainty. When both partners finally agreed to an independent expert determination, the business had declined enough that both outcomes — sale and buyout — were worse than they would have been before the dispute started.
Deadlock provisions in a well-drafted shareholders agreement address this scenario directly: typically through an independent expert appointed by a neutral body, or a “shotgun clause” that forces one partner to either buy or sell at a nominated price. Without that clause, mediation is the first step; court-ordered winding up is the last.
Partnership disputes without a deadlock mechanism regularly cost both parties $50,000–$200,000 in legal fees before resolution. The earlier you bring in neutral expertise — whether legal, financial, or advisory — the more options you have and the cheaper the outcome.
Getting Help With a Partnership Exit
If you’re considering exiting a business partnership — whether by buying out your co-owner, selling your share, or putting the whole business to market — the first step is understanding what your business (and your share of it) is actually worth.
Miro Capital works with business owners across Australia on exactly these situations: valuing the business independently, structuring the exit, and where appropriate, finding a third-party buyer for the whole business when that’s the better path.

Frequently Asked Questions
How do I quit a business partnership?
Review your partnership agreement or shareholders agreement for the exit clause. Give written notice to your partners, negotiate a buyout price based on an independent valuation, settle all financial obligations, and formally transfer your interest. Get legal and financial advice before you give notice — the sequence of steps matters.
How to close a partnership in Australia?
Give written notice to all partners, complete existing contracts, settle all debts, distribute remaining assets according to each partner’s interest, cancel the ABN and GST registration with the ATO, and deregister the business name with ASIC. When partners agree, the process typically takes one to three months.
Can I remove myself from a business partnership?
Yes — by giving written notice (for an indefinite partnership) or following the exit process in your agreement. Your interest must be formally transferred and obligations settled before your liability ends. Until that’s done, you remain legally and financially responsible for partnership activities.
How do you close a business partnership?
Either dissolve the whole partnership (wind up operations, settle debts, distribute assets, cancel registrations) or have one partner buy out the other so the business continues. Dissolution destroys going-concern value and is usually the last resort. A buyout at a fair independently-determined price is typically better for both parties.
Can I just walk away from a partnership?
No. Walking away without formal exit steps leaves you exposed to ongoing liability. Partners can be held responsible for partnership debts incurred after they thought they’d left, if no formal notice was given and no formal transfer executed. Document the exit properly — don’t just stop showing up.
How to get rid of a 50/50 business partner in Australia?
A 50/50 deadlock requires your shareholders agreement’s deadlock mechanism (shotgun clause or independent expert), mediation, or as a last resort, court orders. Without a deadlock provision, disputes are expensive and slow. The first step is an independent business valuation to anchor negotiations before positions harden.
