Understanding Business Taxation Structures
The key difference between a sole trader and a company lies in how money flows and how it's taxed, impacting the final income tax for the business.
Sole Trader Tax Rate Flow
As a sole trader, you and the business are the same legal entity. All profit flows directly to you and is taxed at your personal marginal tax rates. There is no special tax rate for a sole trader.

Company Tax Rate Flow
A company is a separate legal entity. It earns the profit and pays tax at the flat company taxation rate. You, as the director, are an employee and are paid a salary, which is then taxed at personal rates.
