Steps to Take if You Need to Complete a Self-Assessment Tax Return
If you have income that needs to be declared through Self-Assessment, here’s a step-by-step guide to what you’ll need to do:
1. Notify HMRC
If you haven’t sent a tax return before, you must inform HMRC by 5th October after the end of the tax year in which you received untaxed income. Failing to do this could result in a fine.
2. Keep Records
Keeping accurate records is essential for completing your tax return. If you’re self-employed, you’ll need to track:
Your business income and expenses (as a sole trader or partner in a business partnership).
3. Choose an Accounting Method
You’ll need to decide how to record your income and expenses:
Traditional Accounting
Record income and expenses based on the date you invoiced or were billed, even if the money was received later.
Example: If you invoiced a client on 28th March 2022, you record it for the 2021/22 tax year, even if the payment arrives in the next tax year.
Cash Basis Accounting
Record income and expenses only when the money is received or paid. This is ideal for small businesses earning £150,000 or less.
Example: If you invoiced on 15th March 2022 but didn’t receive payment until 30th April 2022, you’d record it for the 2022/23 tax year.
4. Maintain Proof of Income and Expenses

Based on your tax return, HMRC will calculate how much tax you owe. You’ll need to settle any outstanding amount by the same 31st January deadline.
