As a sole trader, your business income is treated as your personal income for tax purposes. This means you report your business profit on your personal tax return and pay income tax at your marginal rate. While the simplicity of a sole trader structure is appealing, it comes with specific tax obligations including quarterly instalments, GST/VAT (if registered), record keeping and potentially paying both income tax and self-employment contributions.
