Pty Ltd vs Sole Trader

The Short Version

• Sole trader: cheap, simple, flexible — but you and the business are legally the same person. You keep all the profit and carry all the risk.
• Pty Ltd company: more expensive and more regulated — but the company is a separate legal entity. Your personal assets are generally protected, and there are real tax advantages once profits grow.

Most small businesses start as sole traders. Many should — and many shouldn't.

Sole Trader: The Basics

A sole trader is an individual carrying on a business in their own name. There is no separate legal entity. You register an ABN, you can trade under a registered business name if you want, and you report business income and expenses in your personal tax return.

Pros

• Cheap and fast to set up — an ABN is free and takes minutes
• Minimal ongoing compliance — no ASIC filings, no separate company tax return
• Full control — every decision is yours
• Losses can offset other personal income (subject to the non-commercial loss rules)

Cons

• Unlimited personal liability — every business debt is your debt. Clients can sue you personally. Creditors can chase your house, your car, your savings.
• Personal tax rates apply to all profit, up to 45% plus Medicare levy
• Limited ability to bring in co-owners or investors — a partner means restructuring
• Less perceived credibility with corporate clients, particularly for higher-value contracts

Pty Ltd Company: The Basics

A proprietary limited company is a separate legal entity registered with ASIC under the Corporations Act 2001 (Cth). It has its own ACN, its own ABN, its own tax file number, and its own bank accounts. The people behind it — the directors and shareholders — are legally distinct from the company itself.

Pros

• Limited liability — as a shareholder, your loss is generally capped at what you paid for your shares
• Flat 25% company tax rate (for base rate entities) — significantly lower than the top personal rate
• Ability to retain profits in the company and reinvest at the company tax rate rather than paying them out as personal income
• Easier to bring in co-founders and investors via share issues
• Structured succession and sale — you can sell shares in the company rather than the underlying business
• Perceived credibility — many corporate and government clients will only contract with a company

Cons

• Higher set-up cost — ASIC fees plus advisor costs
• Ongoing compliance — annual ASIC review, separate company tax return, corporate governance obligations
• Director duties under the Corporations Act — including duties of care, good faith, and to prevent insolvent trading
• Losses trapped in the company — they cannot offset your personal income
• Taking money out is more formal — via wages, dividends, or Division 7A-compliant loans, not just transfers

The Tax Question

Tax is often the deciding factor, but not the way people expect. A sole trader pays personal income tax on every dollar of business profit. A company pays 25% on profit, but the shareholder only pays tax when the profit is distributed as a dividend — and gets a franking credit for the tax already paid.

Rough rule of thumb: if the business generates less than about $80,000–$100,000 in profit and you need every dollar to live on, a sole trader is often no worse off after tax. As profit grows — and particularly if you can leave money in the business to reinvest — the company becomes more efficient.

The Liability Question

Every business owner should ask: if the worst plausible thing happened to a customer, employee or supplier because of my business, could I survive it personally?

Trades that carry physical risk, businesses that give advice, companies that hold client money or data, and any business signing high-value contracts should think very carefully before operating as a sole trader. A company plus adequate insurance is usually the right combination.

When to Switch from Sole Trader to Pty Ltd

Common triggers include:

• Business profit consistently over $80,000–$100,000
• Bringing in a co-founder, business partner or investor
• A material increase in liability risk (bigger clients, bigger contracts, bigger deliverables)
• Winning corporate or government work that requires a company counterparty
• Wanting to build value in a separately saleable entity

The small business CGT concessions and rollover reliefs mean the switch can often be made with minimal tax cost — but the transition needs to be planned properly.

Frequently Asked Questions

Is a Pty Ltd company better than a sole trader?

It depends on your situation. A Pty Ltd company gives you limited liability, potential tax advantages once profits grow, and generally more credibility — but it costs more to set up and run, and imposes ongoing ASIC obligations. For a low-risk business earning under about $80,000 in profit, sole trader is often the sensible starting point. Above that, or where liability risk is material, a company usually wins.

How much does it cost to set up a Pty Ltd company in Australia?

ASIC's registration fee is currently in the several-hundred-dollar range and rises each year. On top of that, most businesses pay an accountant or lawyer a few hundred to a few thousand dollars to set the company up properly with a constitution, share structure, and shareholders agreement. There is also an annual ASIC review fee.

What tax rate does a Pty Ltd pay compared to a sole trader?

A base rate entity company (which most small Pty Ltds are) pays a flat 25% tax on profits. A sole trader pays personal income tax on business profits at marginal rates ranging from 0% up to 45% plus Medicare levy. The company rate becomes attractive once your profits push you into the higher personal brackets.

Can I switch from sole trader to Pty Ltd later?

Yes. Many businesses start as a sole trader and incorporate once turnover, profit or risk crosses a threshold. The transition involves setting up the company, transferring assets and contracts to it, dealing with any tax consequences on transfer, and communicating the change to clients and suppliers. Small business CGT concessions can often reduce or eliminate the tax cost of restructuring.

Does a Pty Ltd really protect me from personal liability?

Mostly, but not absolutely. A company is a separate legal person and its debts are its own — that is the main benefit. But directors can still be personally liable for insolvent trading, unpaid PAYG and superannuation, personal guarantees they sign for the company, and their own negligent or unlawful conduct. Limited liability is powerful but not unlimited.
