FAQ

Self Assessment FAQs

What expenses can I claim as a sole trader?

You can claim expenses that are wholly and exclusively for business purposes, including office costs, travel, stock, marketing, professional subscriptions, and a proportion of home office costs if you work from home.

What is the penalty for late filing?

A £100 penalty is automatically charged if your return is up to 3 months late. Additional penalties apply beyond 3 months, including daily penalties and percentage-based charges on tax owed.

What records should I keep?

You should keep records of all income and expenses, bank statements, invoices and receipts, P60s and P11Ds from employment, and any other documents relating to your tax affairs. Records must be kept for at least 5 years after the filing deadline.
