Invoice rules in the UK at a glance

Tax

VAT, standard rate 20%. See all rates and the VAT calculator

Tax number

VAT registration number

Not registered for tax

A business that is not VAT registered must not charge VAT or show VAT on its invoices and cannot issue VAT invoices. It still issues an ordinary invoice with the standard details.

Small invoices

A simplified VAT invoice can be issued where the supply is £250 or less including VAT; it shows your name, address and VAT number, the tax point, a description, and for each VAT rate the total including VAT and the rate. Above £250 a full or modified invoice is required.

Payment terms

30 days after the customer receives the invoice or the goods or services are delivered, whichever is later, if no date was agreed. Agreed terms between businesses should normally be no more than 60 days (30 days for public authorities).

Late payment

Late Payment of Commercial Debts (Interest) Act 1998: in business-to-business contracts the supplier can claim simple statutory interest plus a fixed sum for debt recovery costs, unless the contract sets a different (substantial) remedy. Fixed compensation: £40 for debts under £1,000; £70 for £1,000 to £9,999.99; £100 for £10,000 or more (once per invoice). Reasonable extra recovery costs can also be claimed.

Keep records

At least 6 years for VAT records (10 years for VAT One Stop Shop or Mini One Stop Shop records).
