Self-Employed Invoice Template UK: What to Include in 2026

Self-Employed Invoice Template for UK Sole Traders

If you're self-employed in the UK, you need to issue invoices for the services or goods you provide. Unlike limited companies, sole traders have slightly different requirements — but your invoices still need to be professional and HMRC-compliant. Here's your complete guide.

Do Self-Employed People Need to Issue Invoices?

Yes. If you're self-employed and provide goods or services to businesses or individuals, you should issue an invoice for every transaction. This is essential for:

• Getting paid (obviously!)
• Keeping accurate records for your Self Assessment tax return
• Meeting HMRC record-keeping requirements
• Maintaining professional relationships with clients

What to Include on a Self-Employed Invoice

As a sole trader, your invoice must include:

• Your full name (or trading name if you use one)
• Your address
• Your contact details (email, phone)
• Client's name and address
• A unique invoice number
• The invoice date
• A clear description of work done
• The amount charged
• Payment terms and due date
• Your bank details

What NOT to Include (Common Mistakes)

• Don't add VAT unless you're VAT registered (turnover above £90,000)
• Don't use a company registration number — sole traders aren't registered at Companies House
• Don't write "Ltd" or "Limited" after your name — this is illegal if you're not incorporated

Sole Trader vs Limited Company Invoices

The main differences:

• Sole traders use their personal name; limited companies use the registered company name
• Limited companies must show their company registration number
• Limited companies must show their registered office address
• Both must show VAT numbers if VAT registered

Record Keeping for Self-Employed

HMRC requires self-employed individuals to keep records of all income and expenses for at least 5 years after the 31 January submission deadline. Keep copies of every invoice you issue and every receipt for business expenses. Digital records are perfectly acceptable.

Tips for Self-Employed Invoicing

• Invoice immediately after completing work — delays cost you money
• Use consistent numbering (INV-001, INV-002, etc.)
• Keep a simple spreadsheet tracking all invoices issued
• Set clear payment terms upfront before starting work
• Follow up politely but firmly on overdue payments
