When Should I Consider Changing From Sole Trader to a Company?

There's no single trigger that applies to every business — but a combination of growing profit, growing risk, and growing complexity is usually what makes the conversation worth having properly. The structure can be changed later, but doing so can involve tax, legal, contractual, transfer and administrative consequences — it's worth revisiting deliberately rather than only when a problem forces the issue.

• Profit has grown meaningfully. As a sole trader, all profit is taxed at your personal marginal rate, which climbs as income rises. A company's flat tax rate can create genuine planning opportunities once profit is consistently substantial — though the actual benefit depends heavily on your specific numbers and what you do with the profit afterward.

• Risk exposure has increased. Larger contracts, more stock, equipment finance, or employees all increase what could go wrong — and as a sole trader, your personal assets remain exposed to all of it.

• You're bringing in a partner or investor. A company structure makes it considerably easier to formally share ownership, issue shares, and bring in outside capital than a sole trader structure does.

• You want a cleaner separation between yourself and the business. For credibility with larger clients, for estate and succession planning, or simply for your own clarity between personal and business finances.

• You're planning to sell or exit eventually. A properly structured company can be considerably easier to sell, in whole or in part, than transferring an entire sole trader business.

• Registering a new company with ASIC, including a new ABN, TFN and any required GST registration.

• Transferring business assets, contracts and, where relevant, employees into the new entity.

• Understanding the tax consequences of the transfer — potentially including capital gains tax, though certain small business restructure concessions may reduce or defer this.

• Updating contracts, invoicing, business names and registrations to reflect the new structure.

• Establishing proper company governance — director duties, company records, and the payment structures covered in the company money guides.

This is genuinely more involved than the original decision to start as a sole trader — which is exactly why it's worth planning for deliberately, rather than reacting to a problem after it's already occurred.

Restructuring earlier, while the business is smaller, is generally simpler and less costly than doing it later once significant assets, contracts and goodwill have built up. A business that waits until a specific crisis — a large new contract, a lawsuit threat, an investor opportunity — to restructure is making the decision under pressure, with less room to plan the transition properly.

Rather than asking “should I become a company,” a more useful question is: “if I imagine this business in two years — bigger, more profitable, more exposed — would I wish I'd made this change earlier?” If the honest answer is yes, it's worth having the conversation now, while the transition is still relatively straightforward.

• Has my profit grown to a level where the tax rate difference between structures is genuinely material?

• Has my risk exposure — contracts, stock, staff — grown meaningfully since I started?

• Am I planning to bring in a partner, investor, or eventually sell the business?

• Have I actually modelled the numbers, or am I going on a general feeling that it's “time”?

• you want the tax and financial impact of restructuring modelled properly before deciding;

• you're bringing in a partner or investor and need the right structure in place first;

• you're growing quickly and want to understand the risk exposure trade-offs of staying a sole trader; or

• you've decided to restructure and want the transition — including any CGT concessions — handled correctly.
