Reverse Charge VAT Explained: What It Is & How It Works

What is Reverse Charge VAT?

Value added tax (VAT) is an indirect tax generally levied on buyers at all stages of the supply chain. In most cases, in the approximately 175 countries where VAT applies, the seller collects the VAT from the customer and then remits the funds collected to the country’s taxing authority.

But in some cases, businesses are allowed to apply the “reverse charge” mechanism. This allows businesses who sell to other businesses (but who have no other VAT obligation in a country) can issue an invoice stating that the “reverse charge” applies. The seller doesn’t collect VAT. The buyer instead self-assesses the VAT rate that would have been due on the transaction and pays it to the taxing authorities themselves on their next VAT return.

Why does the reverse charge mechanism exist?

The reverse charge mechanism simplifies cross border business by not requiring businesses who have no other tax obligations in a country to register for and collect VAT. The reverse charge mechanism also combats tax fraud by unregistered remote businesses by placing the onus of VAT compliance on in-country registered businesses.

When Does the Reverse Charge VAT Apply?

Reverse charge VAT generally applies to businesses in countries with VAT but only under certain conditions, including:

Supplier not established locally – A supplier (seller) does not have a physical presence or other presence in a country, which means they’re required to register for that country’s VAT system. If they are locally established, a supplier can’t take advantage of the reverse charge mechanism and should instead simply charge and pay VAT as required.

Customer is VAT-registered – The customer (buyer) must be a business registered for VAT in their jurisdiction. They must prove this by furnishing a valid VAT ID or equivalent tax ID. If the buyer doesn’t have a valid VAT ID (such as an SMB that doesn’t transact enough business to be required to collect VAT yet), the transaction is comparable to a B2C transaction, and the reverse charge mechanism cannot be applied. 

Note that the reverse charge mechanism is also applicable in most countries that have a Goods and Services Tax (GST).

Countries That Use the Reverse Charge VAT Mechanism

EU Member States

Under the EU VAT Directive, cross-border B2B transactions are eligible to apply the reverse charge mechanism. 

Some EU countries also apply reverse charge domestically in certain high-fraud sectors like construction, telecommunications, electronics, natural gas/electricity, and investment gold. This places the onus of VAT on the buyer even in domestic transactions to ensure proper tax collection. But note that each EU member state gets to make their own rules when it comes to which transactions must be subject to domestic reverse charge. 

UK: Post Brexit VAT Reverse Charge

Though now divorced from the EU’s VAT system due to Brexit, the UK still uses a reverse charge approach to cross-border transactions. 

Like many EU countries, the UK also implements a domestic reverse charge (DRC) on building and construction services transactions. That means buyers, not suppliers, are responsible for paying VAT on these transactions. 

Countries Where Reverse Charge Can Be Applied

More than 165 VAT and GST countries allow the reverse charge mechanism, including:

• Australia
• Canada (with the exceptions of British Columbia, Manitoba and Saskatchewan) (GST)
• Egypt
• European Union
• Georgia
• India (GST)
• Indonesia
• New Zealand (GST)
• Norway
• Saudi Arabia
• Singapore (GST)
• South Africa (as of 1 April 2025)
• South Korea
• Switzerland
• United Arab Emirates
• United Kingdom
• Vietnam

Note that some countries have Goods and Services Tax (GST) rather than VAT and these have been indicated with (GST).

Countries Where Reverse Charge Cannot be Applied

• Japan - has a reverse charge, but very limited in scope
• Kenya 
• Malaysia
• Nigeria

Some Canadian provinces, like British Columbia, Manitoba, and Saskatchewan also do not allow suppliers to apply the reverse charge mechanism. Always check with the tax authority before attempting to apply a reverse charge.

Reverse Charge Mechanism Examples

Below are some examples of when a supplier/seller might apply the reverse charge mechanism:

Cross-Border SaaS Sales (EU Example)

A SaaS company based in Poland sells a year’s worth of service to another company based in Sweden. In this case, the supplier in Poland can apply the reverse charge mechanism. The buyer in Sweden will be responsible for reporting and paying the VAT they should have been charged on the sale. Note that this only applies if the Polish company has no physical presence, such as employees or offices, in Sweden.

Domestic Construction Industry (UK Example)

The UK has implemented a Domestic Reverse Charge (DRC) on sales in the construction and building industry to combat unusually high historical instances of VAT fraud in this industry. In this case, the buyer (usually a contractor, but can also be the end customer) is responsible for paying VAT. The supplier, i.e., the builder or materials supplier, is required to implement the reverse charge mechanism to ensure that the buyer/end user pays the VAT due.

Postponed VAT Accounting (Imports Example)

Some countries with VAT allow businesses to postpone their VAT payments on imports in an accounting method known as postponed VAT accounting (PVA). With this method, a business imports goods and the VAT on the import is technically due when the goods arrive at the border. But instead, PVA allows businesses to instead apply the VAT payment on their imported goods to their next (usually quarterly) VAT filing and remittance instead. PVA facilitates the flow of business and stops physical goods from being held up in customs.
Not all VAT countries allow PVA. Germany, for example, is a notable exception. 

How Reverse Charge Works: Understanding the VAT Flow

To understand how reverse charge works, it's helpful to know the difference between input tax and output tax. Input VAT is the VAT a business pays on purchases, while output tax is the VAT a business collects on sales. Under normal VAT rules, businesses offset their input tax against their output tax during VAT reporting.

With reverse charge, the foreign supplier doesn't collect output tax from the buyer. Instead, the domestic buyer reports both the input VAT (as a purchase) and output tax (as if they made the sale to themselves) on their VAT return. This ensures compliance with VAT rules while simplifying cross-border supplies of goods and services.

How to Implement Reverse Charge VAT Compliantly

Step 1: Verify Customer VAT IDs

Before applying the reverse charge mechanism, obtain and verify the buyer’s VAT registration number. Most countries allow you to easily verify VAT numbers online through official databases. Or you can use Sphere which verifies VAT IDs across various local databases to ensure validity.

Step 2: Structure Your Reverse Charge Invoice Correctly

Invoices where the reverse charge is applied require extra information. 

Structure invoices like normal, with supplier and buyer’s info, date, invoice number, and list of supplies of goods or services sold and their prices. 

But to stay compliant with reverse charge rules, add a note stating something like:

• “Reverse charge: VAT to be accounted by the purchaser” or 
• “0% VAT (reverse charge)”

Payment processors like Stripe allow you to collect VAT numbers and adjust your invoices so that you are applying the reverse charge mechanism in a compliant manner (more information on how to do this in Stripe here). However, note that these payment processors do not validate tax IDs which is a critical component in applying the reverse charge mechanism correctly. Sphere automatically pulls VAT IDs from your billing system, verifies them and adjusts your invoices to apply the reverse charge mechanism compliantly.

Reverse Charge VAT: Make It Work for Your Business

Reverse charge VAT helps simplify cross-border sales by shifting tax responsibility to the buyer, who likely already has tax responsibility in a country. This reduces the need for foreign VAT registrations, the need for which have historically led to tax noncompliance by the foreign company (often accidentally).

When applied correctly, the reverse charge mechanism makes international sales easier while also keeping tax authorities happy and their coffers full of the funds they need for budget items like schools, roads, and hospitals. 

Businesses who sell cross-border can do business without the administrative hassle of complying in multiple foreign countries, and business flows smoothly between suppliers and buyers.
