🇬🇧 United KingdomAllowable business expenses Official confirmation needed

What expenses can I claim?

As a general principle, a cost can usually be counted as a business expense when it is spent wholly and exclusively for the business — stock, tools, business travel, business insurance, accountancy fees, and a fair share of home-working costs. Personal spending, and the personal share of a mixed cost, is normally excluded. Keep the receipt and a short note of why the cost was for the business.

🇬🇧 United KingdomVAT / IVA / sales tax Official confirmation needed

Do I need to register for VAT?

VAT registration in the UK is driven by your VAT taxable turnover over a rolling 12-month period, and by whether you expect to pass the threshold in the next 30 days. You may also register voluntarily below the threshold. Because the threshold figure is reviewed by government, check the current amount on GOV.UK before deciding — this app does not treat any figure as final.

🇬🇧 United KingdomRecord-keeping Official confirmation needed

What records must I keep?

Self-employed people are generally expected to keep records of all sales and income, all business expenses, VAT records if registered, PAYE records if they employ anyone, and personal income. HMRC publishes how long records must be kept, and the period differs between sole traders and companies — check the current requirement rather than relying on a remembered number.

🇬🇧 United KingdomDeadlines Official confirmation needed

What are the filing deadlines?

The UK tax year runs 6 April to 5 April. Self Assessment returns are filed after the year ends, with an online filing deadline in January and payments on account that can fall in January and July. Companies follow their own accounting reference date instead. Confirm your personal dates in your HMRC account — they depend on when you registered.

🇬🇧 United KingdomInvoicing Official confirmation needed

What must an invoice show?

A business invoice normally shows a unique number, your business name and address, the customer's details, a clear description of what was supplied, the date, and the amount due. If you are VAT registered there are extra requirements, including your VAT number and the VAT charged. Check the current VAT invoice requirements before issuing your first VAT invoice.

What changed this year?

Making Tax Digital continues to expand for self-employed income and property income, phased by income level. This prototype does not connect to HMRC and cannot tell you whether you are in scope. Treat this as a prompt to check the current MTD timetable on GOV.UK.
