Frequently Asked Questions About Invoicing in the United Kingdom
How do I create a VAT invoice in the United Kingdom?
To create a VAT invoice in the United Kingdom, you need to include your business name, VAT registration number, invoice number, date, buyer details, an itemised list of goods or services, the VAT amount at 15%, and the total including VAT. Our free invoice generator includes all these fields automatically, ensuring your invoices are HMRC-compliant every time.
What must a tax invoice include according to HMRC?
According to HMRC, a valid tax invoice must contain: the words "Tax Invoice", the seller's name, address, and VAT registration number, the buyer's name and VAT number (for invoices over £5,000), the date of issue, a unique serial number, a full description of goods or services supplied, the quantity or volume, the price excluding VAT, the VAT rate (15%), the VAT amount in pounds, and the total price including VAT.

Yes! SmartSheets offers a completely free invoice generator designed specifically for UK businesses. You can create professional, HMRC-compliant VAT invoices with automatic 20% VAT calculation, download them as PDFs, manage your clients, and track payments — all at no cost. No credit card required.
What is the VAT rate in the United Kingdom?
The standard VAT (Value-Added Tax) rate in the United Kingdom is 15%, effective since 1 April 2018. This rate applies to most goods and services. Certain basic food items are zero-rated (0%), and some financial and educational services are exempt from VAT. Our invoice generator automatically applies the standard 15% rate.
Do I need to register for VAT in the United Kingdom?
In the United Kingdom, VAT registration with HMRC is compulsory if your business's taxable turnover exceeds £1 million in any consecutive 12-month period. Voluntary registration is possible if your turnover exceeds £50,000. Once registered, you must charge VAT on your supplies and issue proper tax invoices that comply with the Value-Added Tax Act.
How do I add VAT to an invoice?
To add VAT to an invoice, calculate 20% of the subtotal amount (excluding VAT) and add it to get the VAT-inclusive total. For example, if your goods or services total £1,000 excluding VAT, the VAT amount is £200 (£1,000 × 20%), making the total £1,200 including VAT. Our free invoice generator calculates this automatically for every line item you add.
