Preparing for your self-assessment tax return doesn't have to be stressful if you approach it systematically.
Start by gathering your income records — invoices, payment summaries, and any P60s or other employment income documents if applicable. For sole traders, this means a full record of all business income for the tax year.
Next, compile your expense records. This includes receipts, bank statements, and mileage logs. Remember that only legitimate business expenses can be claimed, and they must be supported by evidence.
If you use cloud accounting software like Xero or QuickBooks, much of this information will already be organised. If not, consider whether now is the time to make the switch — it can save significant effort next year.
Finally, don't leave it to the last minute. The self-assessment deadline is 31 January, but starting your preparation in the autumn gives you time to address any gaps or questions before the rush.
If you'd prefer not to go it alone, our self assessment support can prepare and submit your return on your behalf.
