How much tax do you pay on profits as a sole trader?

Your tax is calculated on your taxable profit, which is turnover minus allowable expenses and capital allowances, using standard Income Tax bands. You'll also owe Class 2 and Class 4 National Insurance, both worked out from the same profit figure rather than a fixed rate for every trader.

Does a sole trader need a profit and loss statement?

HMRC does not require a formal profit and loss statement in the way a limited company files one, according to HS222. You still need records that produce an accurate taxable profit figure for your Self Assessment return, so keeping a running summary makes the job far easier even though it isn't a legal filing requirement.

What are the disadvantages of working as a sole trader?

Sole traders carry unlimited personal liability for business debts, which is the most significant drawback according to government guidance on becoming a sole trader. Other common downsides include the full weight of admin and record-keeping falling on one person, no separation between personal and business assets, and less access to some financing routes available to limited companies.

What are the new rules for sole traders in the UK?

The main change affecting sole traders is the phased rollout of Making Tax Digital for Income Tax, which requires digital record-keeping and quarterly updates once a trader's qualifying income passes the relevant threshold. HMRC's guidance sets out the exact thresholds and sign-up timelines that determine when this applies to you.
