Going into business with another person can create momentum, shared capability and more capacity to grow. It can also create financial and legal exposure that is easy to underestimate when the relationship is new and everyone is optimistic.

A successful partnership is not built solely on trust or a good business idea. It needs clear ownership arrangements, disciplined financial systems and a practical plan for the situations no one wants to think about, including disagreement, illness, debt, a sale or a partner leaving.

Start by choosing the right structure for the business and the risk

A partnership can be a straightforward way for two or more people to operate a business together. It is generally less formal to establish and administer than a company, but that simplicity can come with significant personal exposure.

Under state and territory partnership laws, partners in an ordinary general partnership can have personal liability for business debts and obligations. The exact legal position depends on the jurisdiction and the type of partnership involved, so it is important to obtain legal advice before assuming that an informal arrangement protects personal assets.

This does not mean a partnership is inherently the wrong choice. It means the structure should match the business’s risk profile. A low-risk professional or service business may have different needs from a business that holds stock, signs long leases, borrows heavily, employs staff, provides regulated services or enters long-term customer contracts.

Before commencing, consider:

  • What assets will the business own, lease or use?

  • Will either partner provide a personal guarantee to a bank, landlord or supplier?

  • Could the business face customer claims, professional negligence claims or workplace claims?

  • Will employees, contractors or subcontractors be engaged?

  • Does the business need particular licences, permits or industry registrations?

  • Would a company, trust or another structure provide a more suitable framework as the business grows?

Insurance is also part of the structure discussion. Depending on the business, this may include public liability, professional indemnity, workers compensation, cyber cover, management liability, business interruption and product liability insurance. Insurance does not replace good governance, but it can help manage risks that a partnership agreement cannot eliminate.

A registered business name can help the business trade under a chosen name, but it is not the same as a trade mark or a guarantee that another business cannot use similar branding. If the name, logo or reputation will be valuable, trade mark advice should be considered early.

Put the partnership agreement in writing before money changes hands

A written agreement is not always required for a partnership to exist. However, relying on conversations, text messages and goodwill is rarely a sound long-term strategy.

Where there is no clear agreement, the relevant partnership law may fill the gaps. For example, default rules can affect how profits and losses are shared, how decisions are made and what happens when a partner leaves. In New South Wales, the default position includes equal sharing of capital, profits and losses unless the partners agree otherwise. Other jurisdictions have their own legislation, so the agreement should be prepared with the governing state or territory clearly in mind.

A strong partnership agreement should address the practical questions that tend to cause disputes later, including:

  • each partner’s ownership percentage;

  • initial capital contributions and whether they are equity or loans;

  • responsibility for future funding;

  • profit and loss sharing arrangements;

  • authority to sign contracts, borrow money or commit the business to spending;

  • daily roles, working hours and decision-making responsibilities;

  • what happens if one partner contributes more time than the other;

  • rules for partner drawings and reimbursements;

  • ownership and use of intellectual property, client lists and business records;

  • insurance responsibilities;

  • treatment of confidential information;

  • dispute resolution procedures;

  • circumstances in which a partner may retire, be bought out or be required to leave;

  • arrangements for death, incapacity, bankruptcy or serious misconduct; and

  • valuation and payment terms when an interest is sold or transferred.

The agreement should be commercially realistic. A clause requiring unanimous approval for every decision may sound fair, but it can make the business difficult to run. On the other hand, allowing one partner to make large financial commitments without a spending limit can expose everyone unnecessarily.

It is usually helpful to separate decisions into categories, such as routine operational matters, significant expenditure, borrowing, hiring staff, entering leases, changing prices, admitting a new partner and selling the business.

Separate capital, loans, profits and drawings

Many partnership problems arise because the partners use the word “money” to describe several very different things.

At a minimum, the business records should distinguish between:

  • capital introduced by each partner;

  • loans made by a partner to the partnership;

  • income earned by the business;

  • business expenses and liabilities;

  • amounts drawn by partners for personal use;

  • retained cash held for future costs or expansion; and

  • profit allocated to each partner.

This distinction matters because not every amount taken from the business is income, and not every amount left in the bank belongs equally to the partners. A partner who advances funds to cover a short-term cash shortfall may expect repayment ahead of a distribution of profit. Another partner may regard the same payment as additional capital. Without clear records and agreement, both may feel justified.

Maintain individual partner capital and current accounts from the start. These accounts should show what each partner has contributed, borrowed, withdrawn or become entitled to receive. They are particularly important if ownership percentages, contributions or drawings are unequal.

The business should also have a formal cash management process. Agree on:

  • the bank accounts to be used;

  • who can access online banking;

  • payment approval limits;

  • the frequency of bank reconciliations;

  • how GST, PAYG withholding, superannuation and other liabilities will be funded;

  • the minimum cash reserve to be retained in the business; and

  • the circumstances in which further capital may be requested.

Avoid treating the business account as an extension of personal finances. Personal expenses paid from partnership funds can create bookkeeping issues, tax consequences and resentment between partners. They can also make it difficult to understand whether the business is genuinely profitable.

Understand how partnership income is taxed

For income tax purposes, a partnership lodges a partnership tax return, but it does not generally pay income tax on the partnership’s net income. Instead, each partner includes their share of the partnership’s net income or loss in their own tax return and is personally responsible for the tax on that share.

This has an important cash-flow consequence. A partner may be taxed on their share of partnership income even if the partners agree to retain some of the cash in the business for stock, equipment, debt repayments or growth. The partnership agreement should therefore deal with tax distributions or a sensible process for ensuring partners can meet their personal tax obligations.

The partnership needs its own tax file number and Australian Business Number, and it must keep records that support its income, deductions, asset purchases, debt balances and distributions between partners. It may also need to lodge business activity statements where it has GST, PAYG withholding or PAYG instalment obligations.

GST registration is required where the partnership’s GST turnover meets the applicable registration threshold. For most businesses, the current threshold is $75,000, while separate rules apply to certain activities and not-for-profit entities. GST turnover is not the same as profit, so monitoring sales is essential even in a business with modest margins.

Partners should also understand that they cannot simply place themselves on payroll as though they were employees of the partnership. Amounts described as a partner’s salary or wage are not treated in the same way as employee wages for income tax purposes. A payment arrangement for a working partner should be documented carefully because it can affect the allocation of partnership profit between the partners.

Partners are responsible for their own superannuation planning. The partnership may still have superannuation, PAYG withholding and other obligations for eligible employees and, in some cases, contractors.

Other tax issues can arise depending on the business and its assets, including:

  • capital gains tax when an ownership interest or business assets are sold;

  • GST consequences when the business is transferred or restructured;

  • payroll tax, which differs between states and territories;

  • duty on transfers involving land or other dutiable property;

  • land tax where relevant property is held or used; and

  • fringe benefits tax where benefits are provided to employees.

These issues should be reviewed before a significant transaction is signed, rather than addressed after settlement.

Build transparency into financial reporting and decision-making

A partnership works best when neither partner is surprised by the financial position of the business.

Regular reporting should be built into the operating rhythm of the business, not reserved for EOFY. Monthly management reports can help partners monitor sales, gross margin, overheads, overdue debtors, stock levels, cash flow, tax liabilities and business debt.

A useful monthly partnership meeting may cover:

  • actual results compared with budget;

  • bank balances and expected cash needs;

  • unpaid customer invoices;

  • supplier debts and upcoming commitments;

  • GST and other tax liabilities;

  • employee costs and superannuation payments;

  • major contracts, risks and opportunities;

  • partner drawings and loan balances; and

  • decisions requiring approval.

The reports do not need to be complicated. They do need to be reliable, timely and understood by both partners.

Consider using accounting software with appropriate user permissions, bank feeds and document storage. Keep invoices, contracts, loan documents, lease agreements and insurance policies organised and accessible. If only one person controls the records, bank account and software login, the business has a governance weakness.

A practical scenario

Two business owners establish a partnership to run a design and construction business. One partner handles sales and project delivery, while the other manages suppliers and finance.

The business grows quickly, but the partners never formally agree how much cash should remain in the business. One partner begins taking regular drawings because they believe the business is profitable. The other expects the cash to be retained for materials, wages and upcoming BAS obligations.

Neither partner has acted dishonestly, but the lack of an agreed drawings policy creates a cash shortage and an argument about who should contribute additional funds. A clear agreement, monthly reporting and partner current accounts could have identified the issue earlier and provided a fair process for resolving it.

Plan for change, not just the start-up phase

Partners often spend considerable time discussing how to launch the business and very little time discussing how it will end or change.

An exit plan should cover voluntary retirement, a sale to an existing partner, admission of a new partner, incapacity, death, financial distress, divorce-related pressures, misconduct and a breakdown in the working relationship. These events are not necessarily signs of failure. They are normal commercial risks that should be anticipated.

The agreement should contain a workable valuation process. A valuation may need to consider:

  • plant, equipment and stock;

  • cash and unpaid debts;

  • loans and other liabilities;

  • work in progress;

  • customer contracts;

  • goodwill and brand value;

  • intellectual property;

  • employee entitlements; and

  • the commercial impact of one partner departing.

The partners should decide whether the value will be set by an agreed formula, an independent valuer, an accountant, or a combination of these methods. It is also important to agree on payment terms. A business may be valuable on paper but unable to fund a large immediate buy-out without borrowing or affecting operations.

A change in partnership membership can have more consequences than simply updating a business name record. Depending on the circumstances, it may affect the partnership’s tax registrations, GST treatment, asset ownership, financing documents, customer contracts and insurance policies. The legal and tax position should be reviewed before an incoming or outgoing partner signs transfer documents.

Selling or transferring an interest may also create capital gains tax consequences. In some circumstances, a restructure into a company or another entity may be possible, but any available rollover or concession depends on strict conditions and should be assessed at the time of the transaction.

A partnership is stronger when expectations are documented

The most successful partnerships combine shared ambition with clear boundaries. The partners know what they own, what they owe, how they are paid, who can make decisions and what will happen if circumstances change.

A written agreement, disciplined bookkeeping, regular reporting and early legal and tax advice can reduce uncertainty before it becomes conflict. The right structure is not just about starting a business efficiently. It is about giving the business a stable foundation for growth, changing circumstances and eventual succession.
