Do I Need to Include VAT on Invoices? (UK Guide)
Understanding VAT requirements for UK invoices. When you must charge VAT, registration thresholds, and what to include on VAT invoices.
VAT (Value Added Tax) can be confusing for UK businesses. This guide explains when you need to charge VAT, what to include on invoices, and how to stay compliant with HMRC regulations.
When Must You Charge VAT?
You must charge VAT if:
- ✅ Your annual turnover exceeds £90,000 (2026 threshold)
- ✅ You're VAT registered (mandatory or voluntary)
- ✅ You're selling taxable goods or services
If you're not VAT registered, you cannot charge VAT on your invoices.
VAT Registration Threshold (2026)
You must register for VAT if your taxable turnover in the last 12 months exceeds £90,000. You can also register voluntarily if you're under the threshold.
Important:
- • Monitor your turnover monthly
- • Register within 30 days of exceeding the threshold
- • You can register voluntarily even if under £90,000
- • Once registered, you must charge VAT on all taxable sales
What Must Be on a VAT Invoice?
If you're VAT registered, your invoices must include:
Required Information:
- ✅ Your VAT registration number
- ✅ The words "Tax Invoice" or "VAT Invoice"
- ✅ VAT amount for each item (usually 20%)
- ✅ Total VAT charged
- ✅ Total amount including VAT
- ✅ All standard invoice requirements (name, address, invoice number, etc.)

What If You're Not VAT Registered?
If you're not VAT registered:
- • Do NOT charge VAT on your invoices
- • Do NOT include a VAT number
- • Do NOT show VAT amounts
- • Your prices are the final amount (no VAT added)
Warning: Charging VAT when you're not registered is illegal and can result in fines from HMRC.
Benefits of VAT Registration
Even if you're under the threshold, you might want to register voluntarily:
- ✅ Claim back VAT on business expenses
- ✅ Look more professional to larger clients
- ✅ No surprise registration if you grow quickly
- ✅ Better for B2B clients who can reclaim VAT
