5 Key Features of a Sole Proprietorship

Summary

  • A sole proprietorship is Australia’s simplest and most common business structure, requiring only registration of a business name and tax file number, with business income taxed as personal income and minimal ongoing reporting obligations.
  • Sole proprietors retain complete ownership and control, keep all profits without sharing, and benefit from straightforward dissolution, but face significant limitations in raising capital compared to partnerships or company structures.
  • Unlimited personal liability is the key risk of sole trading, as the business and owner are legally the same entity, meaning personal assets including property and savings are exposed to business debts and liabilities.
  • This article is a guide to sole proprietorships for individuals and small business owners in Australia, explaining the key features, advantages, and risks of operating as a sole trader.

Tips for Businesses

Register an ABN even if not legally required, as it enables tax deductions and helps clients identify your business accurately. Maintain financial records including tax returns for at least five years. Regularly review whether your business structure remains appropriate as your business grows, particularly if you require additional capital or wish to limit personal liability.

Sole proprietorships (‘sole traders’) are Australia’s most common business entity, offering simplicity, full control and minimal red tape. Sole proprietorships are popular because they are relatively simple to register, operate, and dissolve. Additionally, sole proprietorships offer complete control to the owner, allowing for quick decision-making and flexibility in managing the business. This makes them an attractive option for individuals starting a small business or those looking to maintain direct oversight of their operations. However, the more your business’s goals shift towards growth, the more risky and less appealing a sole proprietorship will likely be. This article will take you through five key features of a sole proprietorship to determine whether this business structure is right for you.

1. Simplicity 

Sole proprietorships are the simplest business structure. Consequently, it is the most common type of business entity in Australia. Sole proprietorships are simple in their setup, management and dissolution. To register a sole proprietorship, you only need to register:

  • a tax file number; 
  • a business name (the fees for registering a business name from 1 July 2024 are $44 for one year and $102 for three years); and 
  • an Australian Business Number (ABN), if you choose. 

While a sole proprietor does not have to have an ABN, it may be prudent to do so for several reasons, such as:

  • obtaining financial advantages – for example, allowing the business to claim tax deductions for any purchases made relevant to the running of your business; and
  • avoiding instances of mistaken identity – for example, allowing clients to precisely identify your business and distinguish other businesses with similar names.

Note that registering for an ABN is simple and free.

Similarly, taxation for a sole proprietorship is simple. Since sole proprietors are not separate businesses, they do not need to file a business tax return. Instead, business income is taxed alongside the sole proprietor’s personal income. Therefore, being a sole trader may even provide you with access to small business tax concessions that are in place to promote business growth. However, given its simplicity and individual basis of taxation, other opportunities for tax minimisation are relatively limited compared to other business structures. 

2. Sole Ownership

Another key feature of a sole proprietorship is that you get to be your own boss. While a sole proprietor might have multiple employees, only one owner exists. This means a sole proprietor has complete control over the business management and operations. The sole proprietor has the responsibility and authority to make and implement all decisions, preventing any ownership disputes that might arise under different structures with more than one owner. Indeed, while a sole trader retains ownership, there are finite avenues to fund and grow the business, in contrast to, say, a partnership or company structure. With such limited ability to raise capital, it may be prudent, and it is possible to change business structures to better align with the business’s present goals.

3. Unlimited Liability

Another key feature of a sole proprietorship is that it carries unlimited liability. Unlimited liability means the sole proprietor is personally liable for the business’s debts and liabilities. Importantly, the business is not a separate entity. Instead, the sole proprietor and the business are one and the same. Due to the lack of distinction between private and business assets under a sole proprietorship, unlimited liability is often considered a major downfall of the sole proprietorship business structure. 

In other business types, such as companies, company directors will be considered separate from the company itself. In most cases, this will protect their personal assets. If a sole proprietor incurs debts, this risks the sole proprietor’s personal assets. This might include their personal property and savings. 

4. Profit

Another key feature of a sole proprietorship is that it does not have to share its profits. While the sole trader must pay any employee wages and super contributions and comply with workers’ compensation and tax obligations, the business profit does not need to be shared. This means the sole proprietor can return more money to the business operations or draw a higher salary. With the sole proprietor responsible for business profits, they must ensure they pay their own super contributions.

5. Minimal Formality

Another key feature of a sole proprietorship is that there is minimal formality. Unlike other business structures, sole proprietorships have very few reporting requirements. There are very few documents needed for registration and also very few ongoing reporting documents needed.

A sole proprietor will only need to:

  • apply for and use an ABN;
  • use your individual tax file number to file a tax return;
  • report your income and business income and expenses (it is important that you keep your financial records, including tax returns, for 5 years);
  • register to pay Goods and Services Tax (GST) if the annual GST turnover is greater than $75,000;
  • pay income tax at the end of the year;
  • claim a deduction for any personal super contributions; and
  • pay your employees’ wages and super contributions.

For other business structures, there will be ongoing reporting requirements to the Australian Securities and Investments Commission (ASIC).

To dissolve a sole proprietorship is also simple. You simply need to cancel your ABN and business name within 28 days of ceasing trading.
