Buy-Sell Insurance Australia: A Guide to Business Succession Planning
What is buy-sell insurance?
Buy-sell insurance, also known as business succession insurance, helps fund the transfer of a business owner’s interest when a defined trigger event occurs.
It works alongside a legally prepared buy-sell agreement. The agreement sets out what should happen to an owner’s shares or business interest; the insurance provides funding to make that transfer possible.
For Australian business owners, this can help protect both sides of a difficult situation:
The remaining owners can retain control of the business.
The departing owner, or their family and estate, can receive fair value for their interest.
Buy-sell insurance is commonly funded with life insurance, TPD insurance and trauma insurance, depending on the events the owners agree should trigger the arrangement.

Why is business succession planning important?
Many businesses have shareholder agreements, partnership agreements or informal understandings about ownership. Far fewer have a clear, funded plan for what happens if an owner dies, becomes permanently disabled or suffers a serious medical event.
Without a succession plan, the remaining owners may want to buy the departing owner’s share but lack the cash to do so. At the same time, the owner’s family may inherit an interest in a business they do not want to manage, cannot sell easily or need to convert into cash.
This can create avoidable pressure at precisely the wrong time.
A properly structured buy-sell arrangement can provide clarity on:
Who can buy the departing owner’s interest
What events trigger a transfer
How the business will be valued
How the purchase will be funded
How debts and ownership rights will be handled
What happens to decision-making control
How does buy-sell insurance work?
A typical buy-sell insurance strategy has four parts.
1. A buy-sell agreement is established
The owners enter into an agreement that sets out the rules for ownership transfer if a trigger event occurs.
The agreement should be prepared or reviewed by a solicitor. Insurance alone does not create a binding succession plan.
2. The owners determine what the business is worth
The agreement should include a clear valuation method. This may be a fixed value, a formula or a process for obtaining an independent valuation.
A valuation needs regular review. A policy that was appropriate when the business was worth $1 million may be insufficient if the business grows to $3 million.
3. Insurance is arranged to fund the transition
Life, TPD and trauma cover may be arranged to provide funds if an agreed trigger event occurs.
The policy ownership structure is important and should be designed with legal, tax and commercial advice.
4. A trigger event occurs
If an owner dies, becomes totally and permanently disabled or experiences another event covered by the agreement and policy, the insurance proceeds can be used to fund the purchase of their ownership interest.
The remaining owners can retain control, while the departing owner or their estate receives payment in accordance with the agreement.
What events can trigger a buy-sell agreement?
The trigger events are agreed by the business owners and set out in the legal documents. Common examples include:
Death
Terminal illness
Total and permanent disability
Trauma or critical illness
Permanent incapacity
Retirement
Bankruptcy or insolvency
Divorce or relationship breakdown
Loss of a required professional licence
Voluntary exit from the business
Not every trigger can be insured. This is why the agreement and funding strategy need to work together rather than being treated as separate documents.
Buy-sell insurance vs key person insurance
Buy-sell insurance and key person insurance are both important business protection tools, but they solve different problems.
Buy-sell insurance | Key person insurance |
Funds ownership transfer after a defined event | Helps protect the business from the financial disruption of losing a critical person |
Focuses on shareholders, partners and business owners | Can cover founders, directors or key employees |
Helps the remaining owners buy the departing owner’s interest | May help cover lost revenue, recruitment, debt or replacement costs |
Protects ownership continuity | Protects operational and revenue continuity |
A business with multiple owners may need both forms of protection.
For example, the business may need key person cover to stabilise cash flow after losing a founder, while buy-sell insurance provides the funds for the other owners to acquire that founder’s equity from their estate.
Who should consider buy-sell insurance?
Buy-sell insurance can be particularly relevant for:
Partnerships
Shareholder-owned companies
Family businesses
Medical practices and specialist clinics
Accounting and legal firms
Financial services and advisory firms
Construction and engineering businesses
Technology companies and start-ups
Recruitment, HR and consulting businesses
Businesses with two or more owners
Businesses where ownership is valuable but not easily sold
If a business has more than one owner, the owners should be able to answer one question clearly: “What happens to the business if one of us cannot continue?”
If the answer is uncertain, a buy-sell review is worth considering.
Common buy-sell insurance structures
The appropriate ownership structure depends on the business entity, the number of owners, the legal agreement, tax considerations and the intended outcome.
Common approaches can include:
Cross-ownership structure
Each owner holds insurance on the lives of the other owners. If a trigger event occurs, the surviving owners may receive the benefit and use it to acquire the departing owner’s interest.
Corporate or entity ownership structure
The company owns the policies and may use the proceeds to buy back the departing owner’s shares, subject to the legal and tax structure.
Trustee or superannuation ownership structure
In some circumstances, a trust or superannuation-related structure may be considered. These arrangements can be complex and require specialist legal, accounting and financial advice.
There is no universally best structure. The right arrangement depends on the business.
How much buy-sell insurance is needed?
The starting point is the value of each owner’s interest in the business. However, the calculation should also consider:
The current business valuation
Growth projections
Business debt
Each owner’s percentage interest
The value of goodwill and client relationships
Assets, liabilities and retained earnings
Any personal guarantees
Existing succession arrangements
Whether the business has sufficient cash reserves
Cover should be reviewed regularly, particularly after business growth, a major contract, a change in ownership, new debt, a restructure or a material change in profitability.
What can go wrong without a funded buy-sell agreement?
Without clear documentation and funding, a business may face a situation where the surviving owners cannot afford to buy the departing owner’s interest.
Possible consequences include:
The departing owner’s family becoming shareholders or partners
Disagreement over the business value
Pressure to sell business assets
Borrowing at an inconvenient time
Tension between owners and families
Disruption to staff, clients and suppliers
Delays to decision-making and succession
A buy-sell agreement does not eliminate every risk. It creates a clear pathway to manage an ownership transition with greater certainty.
Is buy-sell insurance tax deductible?
Tax treatment can vary significantly depending on the purpose of the policy, ownership structure, business entity and type of cover.
Business owners should not rely on general information when deciding ownership or tax treatment. A solicitor, accountant and qualified insurance adviser should work together to ensure the agreement and insurance strategy align.
Frequently asked questions
Is a buy-sell agreement legally binding?
It can be, provided it is properly drafted and executed. Business owners should obtain legal advice rather than rely on a verbal agreement or template.
Does buy-sell insurance replace a shareholder agreement?
No. Insurance provides funding. A shareholder agreement or buy-sell agreement establishes the legal process for ownership transfer.
Can a business use buy-sell insurance for TPD or trauma?
Yes, depending on the policy and agreement. Many arrangements consider life, TPD and trauma cover to address a range of agreed trigger events.
How often should a buy-sell arrangement be reviewed?
At least annually, and whenever the business value, ownership structure, debts, personal circumstances or succession objectives change.
Is buy-sell insurance only for large businesses?
No. It is often particularly important for SMEs and owner-managed businesses because they may have less cash available to fund a sudden ownership transfer.
Protect ownership. Secure the future.
