If you're not sure if you're self-employed for income tax, you can use a standard set of questions to check.

Filling out your personal tax return
You must keep business records relating to your income and outgoings. You will need these so that your accountant can submit a true and accurate set of accounts or so you can produce your own set of factual accounts.
Record keeping if you're self-employed
Weekend trading and casual profits
This is generally small cash-in-hand income generated by ad-hoc work you perform outside of (and not associated with) your normal day-to-day work. This is taxable and the details must be entered on your annual tax return.
Getting an accountant
Larger businesses with a turnover exceeding £100,000 should have their financial statements prepared by a qualified accountant.
