If you work with international clients, you have probably encountered questions about VAT (Value Added Tax). Should you charge it? At what rate? What information must appear on your invoice? VAT rules differ from country to country, and getting them wrong can result in compliance issues for you or your client. This guide covers the fundamentals of VAT invoicing for freelancers and small businesses that serve clients across borders.
What Is VAT?
VAT is a consumption tax applied at each stage of the supply chain where value is added. Unlike U.S. sales tax, which is collected only at the point of final sale, VAT is collected incrementally. More than 170 countries use VAT systems, including all EU member states, the UK, Canada (GST/HST), Australia (GST), and most countries in Asia, Africa, and Latin America. The United States is one of the few major economies that does not use VAT, relying instead on state-level sales taxes.
When Does VAT Apply to Your Invoices?
Whether you need to charge VAT depends on several factors: where you are located, where your client is located, whether your client is a business or consumer, and what type of service or product you are providing.
If You Are Based in a VAT Country
When you are based in a country with VAT and you sell to a domestic customer, you charge VAT at the local rate. When you sell to a business in another VAT country (such as within the EU), the reverse charge mechanism typically applies: you do not charge VAT, and your client accounts for VAT on their end. When you sell to a customer outside the VAT zone entirely, VAT generally does not apply and the invoice is zero-rated.
If You Are Based in the United States
U.S.-based freelancers generally do not need to charge VAT on invoices to international clients. The U.S. does not have a VAT system, and your services are typically considered exported. However, if you have established a business presence (a fixed establishment) in a VAT country, you may have VAT obligations there. Additionally, some countries require foreign businesses to register for VAT if they sell digital services directly to consumers in that country.
The Reverse Charge Mechanism
The reverse charge is one of the most important concepts in international VAT. Under the reverse charge, the responsibility for reporting VAT shifts from the seller to the buyer. This commonly applies to B2B (business-to-business) transactions between companies in different countries. Instead of the seller charging VAT on the invoice, the buyer self-assesses the VAT and reports it on their own VAT return. This prevents the complexity of foreign sellers having to register for VAT in every country where they have customers.
When the reverse charge applies, your invoice should state "Reverse charge: VAT is to be accounted for by the recipient" and include both your VAT number and your client's VAT number.
VAT Rates Around the World
VAT rates vary significantly by country, and many countries have multiple rates depending on the type of goods or services.
- EU standard rates range from 17% (Luxembourg) to 27% (Hungary)
- UK standard rate: 20%
- Canada GST: 5% (plus provincial HST in some provinces)
- Australia GST: 10%
- Japan consumption tax: 10%
- India GST: 5%, 12%, 18%, or 28% depending on category
- Reduced rates often apply to essential goods and services
What Must Appear on a VAT Invoice
VAT invoices have specific formatting requirements that go beyond what a standard invoice includes. While requirements vary by country, most VAT jurisdictions require the following elements.
- Sequential invoice number
- Date of issue and date of supply (if different)
- Seller's name, address, and VAT registration number
- Buyer's name, address, and VAT registration number (for B2B)
- Clear description of goods or services supplied
- Quantity and unit price (excluding VAT)
- Total amount excluding VAT
- VAT rate applied
- VAT amount
- Total amount including VAT
- Currency used
- Reverse charge notation (if applicable)
InvoiceFold supports VAT-compliant invoice formatting, allowing you to add VAT numbers, apply the correct rate per client, and include reverse charge notations. This ensures your international invoices meet compliance requirements without manual formatting for each jurisdiction.
VAT Registration: Do You Need It?
If you are based in a VAT country, you generally must register for VAT once your taxable turnover exceeds a certain threshold. In the UK, the threshold is currently 90,000 GBP. In many EU countries, the threshold varies. Below the threshold, registration is often voluntary but may be beneficial if your clients are VAT-registered businesses who can reclaim the VAT you charge.
VIES Validation for EU Clients
When invoicing a business client within the EU under the reverse charge mechanism, you should validate their VAT number using the VIES (VAT Information Exchange System) database. This confirms the number is active and legitimate. If the number is invalid, you may be required to charge VAT at your domestic rate instead. VIES validation takes seconds and provides proof of verification that you should keep with your records.
Handling Multiple Currencies
When your invoice is in a currency different from your local currency, you may need to report VAT in your domestic currency using the exchange rate on the date of supply. Keep records of the exchange rates used and the source (such as the European Central Bank or HMRC rates). InvoiceFold's multi-currency support handles conversion automatically and records the exchange rate applied to each invoice for your compliance records.
Getting Started with International VAT
- Determine whether your country has VAT obligations
- Register for VAT if you exceed your country's threshold or choose voluntary registration
- Identify whether each international client is B2B or B2C
- Apply the correct treatment: charge VAT, apply reverse charge, or zero-rate
- Format invoices with all required VAT information
- File VAT returns on schedule and keep detailed records
- Validate EU client VAT numbers through VIES before applying reverse charge
International VAT can seem daunting, but once you understand the basic principles of where to charge, when to reverse charge, and what to include on your invoices, it becomes a manageable part of your invoicing workflow. The key is to set up your invoicing tool correctly from the start and verify each client's VAT status before issuing the first invoice.
