Quick answer
Couples in business do best with a few agreed money rules: clear roles, one business account and separate household accounts, a regular pay amount for each partner, a shared rule for big decisions and borrowing, a written plan for guarantees and security over the home, and an agreed approach if one partner steps back or the relationship changes. Write them down and review them yearly.
Key points
- Agree who does what with the money, and who makes which decisions.
- Keep business and household accounts separate, and pay each partner on a rhythm.
- Set a rule for borrowing: amounts above an agreed level need both partners' agreement.
- Plan for the what-ifs: illness, a new baby, one partner stepping back, separation.
Running a business with your partner can be wonderful. You share the load, you trust each other, and the business becomes something you’ve built together. It can also blur every line there is: work and home, business money and household money, “my decision” and “our decision”.
Couples who thrive in business usually have a few simple money rules — sometimes written down, sometimes just understood. This guide suggests some, with an eye on what matters when you borrow.
Rule 1: agree who does what with the money
In most couple-run businesses, one partner ends up closer to the money: doing the books, paying suppliers, talking to the accountant. That’s fine, as long as both of you know what’s happening.
Agree:
- who pays bills and suppliers
- who reconciles the accounts and how often
- who talks to the accountant, the ATO and any lender
- how the other partner stays informed (a monthly 20-minute money meeting works well)
The partner who isn’t doing the books should still be able to answer: what did the business earn last quarter, what does it owe, and is the ATO up to date?
Rule 2: separate business and household money
business.gov.au says partnerships and companies “must have a separate bank account for tax purposes”. But the separation that really helps couples goes further:
| Account | What goes through it |
|---|---|
| Business everyday | All business income and costs — nothing personal |
| Business tax | GST and tax set-asides, moved weekly |
| Household joint | Each partner’s pay lands here; household bills come out |
| Personal accounts (optional) | A little money each partner doesn’t need to explain |
When the business pays household bills directly, the business’s true performance gets hidden, tax gets harder, and in a company there can be Division 7A questions. See mixing personal and business debt.
Rule 3: pay each partner on a rhythm
Decide how much each partner takes from the business, how often and in what form (drawings, wages, director’s fees or dividends — your accountant will advise). Then stick to it. A regular amount on a regular day turns the household budget from guesswork into a plan. Our guide on paying yourself as a sole trader or director explains the options.
It’s also worth being explicit about fairness. If one partner works full time in the business and the other part time, how is that recognised? These conversations are easier to have early.
Rule 4: set a borrowing rule
Borrowing is where couple-run businesses most often hit friction. One partner sees opportunity; the other sees risk. A simple rule helps:
- Below an agreed amount, the partner running the finances can arrange business finance, and tells the other.
- Above that amount, or anything that uses the home as security, or any new personal guarantee — both partners agree first.
Before any significant loan, talk through the purpose, the amount, the exit and the worst case together. Our page on loans for couple-run businesses explains who usually signs what.
When you’re both comfortable, either of you can start a quick enquiry. Mention that the business is run by both of you and the specialist will make sure both of you are part of the conversation.
Rule 5: treat the home as a joint decision — always
If the home is in joint names, both of you must sign any mortgage over it. Even if it’s in one name, it’s still the family home. The rule is simple: no security over the home unless both of you genuinely agree, and the partner less involved in the business has had the chance to get independent advice. Our page on borrowing against a home in joint names goes into detail.
Rule 6: know every guarantee you’ve signed
Many couples sign guarantees without really registering them — with the bank loan, the equipment finance, the shop lease, a supplier account. Keep a simple list: who guaranteed what, for how much, and how you’d be released. It matters most if things change later. See releasing a personal guarantee.
Rule 7: plan for the what-ifs
Couples in business carry a double exposure: if the business struggles, both incomes suffer at once. It’s worth planning, calmly, for:
- Illness or injury. business.gov.au describes income protection insurance as covering “part of your income if you’re unable to work because of sickness or an accident”. Talk to a licensed adviser about what suits you.
- A new baby or caring responsibilities. Who covers which role, and can the business afford cover?
- One partner stepping back. How is their share of pay and ownership handled?
- Separation. Nobody wants to think about it, but a shareholders’ or partnership agreement that covers it protects you both. business.gov.au notes a partnership agreement “sets clear expectations and helps avoid disputes between partners”.
Rule 8: review once a year
Once a year, sit down with your accountant’s figures and ask:
- Is the business paying us both fairly and sustainably?
- Are our accounts still separate, or has mixing crept back? (The money-mixing check takes two minutes.)
- What do we owe, and what’s securing it?
- Are our roles still right?
- Anything we’d do differently next year?
Rule 9: be honest about credit histories
It’s surprisingly common for one partner not to know the details of the other’s credit file — an old default, a debt from before the relationship, a past bankruptcy. It matters when you borrow together, because lenders usually look at both of you. Each of you can get your credit report for free every three months, according to Moneysmart. Check them together before any significant application, so there are no surprises in front of a lender. Past credit issues are considered case by case, and they’re far easier to deal with when they’re disclosed upfront.
Rule 10: don’t let the business become the only topic
This one isn’t about money, but it protects the money. Couples in business can find every dinner turns into a business meeting. A set time for business talk — the monthly money meeting, say — makes it easier to leave it alone the rest of the week. It also means financial decisions get made with proper attention, not in the car on the way to a job.
A worked example (illustrative)
A couple run a small bakery through a company, both as directors. She handles production; he handles the books. They agree that any borrowing over $20,000, anything secured by their home, and any new guarantee needs both of them to sign off. When the chance comes to buy a second-hand deck oven for $45,000, he brings it to their monthly money meeting with the quote, a cash-flow check and two finance options. They choose an unsecured option sized on turnover, leaving the home out, and both sign the guarantees knowing exactly what they cover.
What if you already have tangled finances?
Most couples in business do, at least a little. Start with the account structure in Rule 2 and a regular pay amount from Rule 3. Those two changes alone untangle most of it within a few months. Our page on separating finances before borrowing walks through the rest.
Where does borrowing fit into all this?
Good money rules make borrowing easier, not harder. A lender assessing a couple-run business wants to see clear accounts, sensible pay and two owners who both understand the loan. If you’ve followed even half these rules, you’ll present far better than most. And if the family home is part of the conversation, read protecting the family home together first.
Borrow as a team, with one person on your side
You run the business together; any loan should be a decision you make together too. Starting an enquiry takes about 60 seconds and there’s no credit check. We won’t send your details off to a crowd of lenders — one specialist takes it and calls to understand both of your roles and what you want to achieve. Please fill in the form accurately, including who owns the home and who would sign, so we can bring you the right option first time.
Frequently asked questions
Should we both be directors or partners?
It depends on your roles, tax position and appetite for risk. Your accountant and a lawyer can advise. For lending, remember that partners and directors are usually both asked to sign or guarantee.
Should we pay both of us even if one works part time?
How you pay each partner is a tax and structure question for your accountant. What matters for the household is agreeing an amount each month the business can sustain.
Who should deal with the lender?
Either of you can start an enquiry. But if both of you will sign or the home is involved, both should understand the loan and be part of the key conversations.
What if we disagree about using the house?
Then the house isn't the right security for now. Look at unsecured options or other property, or revisit the decision once the business has more history.
Do we need a written agreement?
A partnership agreement or shareholders' agreement is strongly worth having. business.gov.au notes a partnership agreement isn't mandatory but helps set clear expectations and avoid disputes.
