Sole Trader Invoice Template UK

Sole Trader Invoice Template UK (Free PDF)

As a sole trader you are the business. There is no company behind you, no Companies House number and no registered office, which is exactly why a sole trader invoice looks a little different from a limited company one. The rules are short, but the ones that catch people out are about names and addresses, not numbers.

This page covers what GOV.UK says a sole trader invoice must show, how to use a trading name properly, when VAT comes into it, what changes if you work in construction, how to charge late payment interest, and how long to keep everything. For limited companies and general UK invoicing, see the UK invoice template.

What a Sole Trader Invoice Must Show

GOV.UK lists the same core details for every business invoice, then adds two lines that only apply to sole traders.

You do not need to put your Unique Taxpayer Reference (UTR) or National Insurance number on an invoice, and you should not. Your UTR is for HMRC and the businesses that pay you under CIS, not for every customer.

Using a Trading Name

You can trade under your own name, such as Sam Patel, or under a business name, such as Patel Decorating. Either is fine on an invoice. If you use a business name, GOV.UK says the invoice must show your own name as well, plus an address where legal documents can be delivered to you.

A trading name also has limits. It cannot include "limited", "Ltd", "limited liability partnership", "LLP", "public limited company" or "plc", because you are none of those. It cannot be offensive, it cannot be the same as an existing trade mark, and some sensitive words need permission first. The usual way to write it is "Sam Patel trading as Patel Decorating", or "Sam Patel t/a Patel Decorating".

The legal documents address does not have to be your home. A business address or a service address works, as long as post sent there actually reaches you.

VAT: Only Once You Are Registered

You must register for VAT when your VAT taxable turnover goes over £90,000 in a rolling 12 month period, or when you expect it to go over £90,000 in the next 30 days alone. Below that you can register voluntarily, which some sole traders do when most of their clients are VAT registered businesses that can reclaim it.

If you are not registered, do not charge VAT, do not show a VAT line, and do not write "VAT 0%" either, as that can suggest you are registered. Just show the total. Once you are registered, your invoice becomes a VAT invoice and needs more detail.

The full VAT invoice rules, including the 20%, 5% and 0% rates, are on the VAT invoice page.

Working in Construction: CIS Deductions

If you are a subcontractor working for a contractor in construction, the Construction Industry Scheme changes how you get paid. The contractor takes a deduction from your labour and pays it to HMRC as an advance on your tax: 20% if you are registered for CIS, 30% if you are not. Materials are not subject to the deduction.

That means your invoice should split labour and materials clearly, so the contractor deducts from the right figure. Show the labour total, the materials total, the CIS deduction and the net amount you expect to receive. The contractor then gives you a payment and deduction statement, which you keep and use to claim the deduction back against your tax bill. Registering for CIS is worth it on its own: it takes the deduction from 30% to 20%.

Payment Terms and Late Payment Interest

Put a due date on every invoice. If you and a business customer never agreed a payment date, the law sets a default of 30 days. Most sole traders use 14 or 30 days and write the date in full, such as "Due by 11 November 2026", rather than "Net 30".

When a business pays you late, the Late Payment of Commercial Debts rules let you claim statutory interest at 8% plus the Bank of England base rate, plus a fixed sum for the cost of chasing the debt. This applies to business customers, not to members of the public.

You do not need to warn customers in advance, but a line on the invoice such as "Late payments may incur statutory interest under the Late Payment of Commercial Debts (Interest) Act 1998" tends to speed things up. The late payment fee calculator works out the interest for you, and the payment reminder generator writes the chasing email.

Getting Paid: Bank Details on the Invoice

Add your account name, sort code and account number, and a payment reference, which is usually the invoice number. As a sole trader you can legally take payment into a personal account, but many banks' personal account terms do not allow business use, and a separate account makes your Self Assessment far easier. Clients paying by bank transfer will see a name check (Confirmation of Payee), so make sure the account name on your invoice matches the name on the account exactly.

Making Tax Digital for Sole Traders

Making Tax Digital for Income Tax is arriving in stages based on your qualifying income from self employment and property: over £50,000 from April 2026, over £30,000 from April 2027 and over £20,000 from April 2028. If you are in, you keep digital records and send quarterly updates to HMRC through compatible software.

MTD does not change what goes on an invoice. It changes how you record it. A consistent invoice number and a clear date on every invoice make your records easy to bring into MTD software. The details are in our UK MTD invoice requirements guide.

How Long to Keep Your Invoices

Keep copies of your invoices and other business records for at least 5 years after the 31 January Self Assessment deadline for the tax year they relate to. An invoice dated October 2026 falls in the 2026 to 2027 tax year, which is filed by 31 January 2028, so you keep it until at least 31 January 2033.

Starting Out: Registration Basics

You can earn up to £1,000 a year from self employment under the trading allowance without telling HMRC. Above that, register for Self Assessment by 5 October after the end of the tax year in which you started. You will get a UTR in the post. You do not need to register with Companies House, and there is no fee to become a sole trader.

How to Make a Sole Trader Invoice in 60 Seconds

Step 1. Open the invoice builder and set the currency to GBP.

Step 2. In your details, write your own name and your trading name if you have one, such as "Sam Patel t/a Patel Decorating", plus your address and email.

Step 3. Add your customer's name and address.

Step 4. Add each job or item with a clear description, the supply date and the price. Do not add a tax rate unless you are VAT registered.

Step 5. Add your sort code, account number and a due date.

Step 6. Download the PDF, send it, and file a copy for your Self Assessment.

Common Sole Trader Invoice Mistakes

Using "Ltd" in a trading name. You are not a limited company, and the name must not suggest you are.

Showing VAT before you are registered. You cannot charge VAT without a VAT number, and a "VAT 0%" line confuses clients.

Missing your own name. A trading name alone is not enough.

Reusing invoice numbers. Every invoice needs a unique number. Our guide to invoice numbering shows simple formats that never clash.

No due date. Without one you fall back to the 30 day default, and chasing gets awkward.
