Which business structure is best?

Adrian Rasmussen • August 14, 2024

A catchy business name, a trustworthy brand and an engaging website or social media presence are all vital to any small business. But don’t underestimate the effect of the business structure.

Choosing whether to operate as a sole trader, company, partnership or trust depends on many factors including cost, the size of the business, whether you have dependants and family members to share income with, and the degree of financial or legal risk involved in running the business.


Sole trader

Many small operators start out as a sole trader, and some decide to continue with this structure.


On the positive side, it’s easy to set it up and, with fewer business reporting obligations, it’s cheaper to run than other business structures.


There are one or two considerations that, depending on your circumstances, could mean a sole trader structure doesn’t work for you.


One of these is the extent of your liability if things go wrong. When you’re a sole trader your liability is unlimited, meaning your assets are at risk in the case of legal action. Some businesses may consider their risk to be too low to warrant changing the business structure or they may choose to find an insurance product to provide some protection.


Tax is another consideration. Among other issues, as a sole trader, you’re liable to pay tax on all income received by the business and you can’t split profits or losses with family members.i


Partnership

Two or more people can form a business partnership and distribute business income among themselves.


Like a sole trader structure, a partnership structure can be slightly cheaper to operate because there are minimal reporting requirements.


All partners are liable for all the debts and obligations of the business although there are different types of partnerships that vary liability among the partners.


For tax purposes, each partner reports their share of the partnership income or loss in their own return and pays tax on any income. Partners cannot claim a deduction for any money they withdraw from the business. Amounts taken from a partnership are not considered wages for tax purposes.ii


Company

A company structure has a number of advantages over a sole trader or partnership structure, but it costs more to set up and operate and there are more reporting requirements.


A company is considered a separate legal entity and has its own tax and superannuation obligations, but company directors have a number of legal responsibilities.


Companies pay an annual fee to be registered with the Australian Securities and Investments Commission (ASIC) and they usually cost more to put together the necessary annual accounts and tax return.


On the plus side, you will be able to employ yourself and claim a tax deduction for your wages.


But be aware of the Personal Services Income (PSI) rules. If more than 50 per cent of the income of the business is produced by your personal exertion, it’s considered PSI and you will pay tax at your marginal rate, rather than the lower company tax rate. This rule affects taxpayers with any business structure.


Trust

A trust is the most expensive and complex business structure to operate but it might be the most appropriate for your needs.


There are some pluses and minuses so expert advice from your accountant and lawyer is crucial. You will need help to decide on the type of trust, to set up a formal trust deed and to carry out annual administrative tasks.


On the positive side, there may be tax advantages and there are some protections from financial and legal liability.


On the flip side, all income earned must be distributed to beneficiaries each year otherwise tax is paid at the highest marginal rate. Also, losses can’t be distributed to beneficiaries, it may be difficult to dissolve or change elements of a trust and it may be more difficult to borrow funds.

After an incredible career dedicated to supporting regional businesses, farming families and rural communities, BMO Business Centre Partner Adrian Rasmussen will officially retire from the partnership effective 30 June 2026. For many across the Western Downs and beyond, Adrian has been far more than an accountant or advisor. Over decades in business, he has built trusted relationships grounded in honesty, loyalty and a genuine understanding of regional life and the people who live it. Adrian’s connection to the country and agriculture has always been at the heart of who he is. He has worked alongside generations of farming families and business owners through seasons of growth, challenge and change, becoming a steady and respected presence for clients, colleagues and the wider community alike. Reflecting on his time at BMO, Adrian said the relationships formed throughout his career have been among the most rewarding parts of the journey. “It has been a privilege to work with so many wonderful people over the years; not only clients, but colleagues and communities who have become lifelong friends,” Adrian said. “Regional communities are built on relationships, trust and supporting one another, and I’m incredibly grateful to have been part of that throughout my career.” BMO Business Centre Managing Partners Kelvin Tyler and Michelle McVeigh said Adrian’s contribution to both the business and the region would leave a lasting legacy. “Adrian has played an incredibly important role in shaping BMO into the business it is today,” they said. “His care for clients, commitment to regional communities and calm, practical approach have earned enormous respect across our industry and the communities we serve. While we will certainly miss having him in the office, we are excited for Adrian and his family as they enter this next chapter.” While stepping away from the partnership, Adrian is looking forward to spending more time with family, on the farm and enjoying a well-earned change of pace after many years dedicated to supporting others. Everyone at BMO Business Centre extends their sincere thanks to Adrian for his years of service, friendship and leadership, and wishes Adrian and his family all the very best for the future.
