Recent discussions have been clouded by misinformation about how VAT systems operate, especially in the context of proposed reciprocal tariffs. This has led to some misconception that VAT systems create unfair trade barriers for US corporations.

We explore the fundamentals of consumption tax systems, such as Value-Added Tax (VAT) and Goods and Services Tax (GST), and their potential impact on international trade compared with tariffs.

VAT Fundamentals

VAT, also known in jurisdictions such as Australia as Goods and Services Tax (GST), is a consumption tax levied on the sale of both goods and services. The tax is applied at each stage of the supply chain that is caught within a country’s VAT regime, from production to the final sale to the consumer. The fundamental principle of VAT is that it is ultimately borne by the end consumer, making it a transparent and equitable form of taxation.

VAT systems are used by 175 countries, including the United Kingdom, European Union, Canada, China, India, and Australia. Despite different terminologies for this tax (such as GST), the underlying principles are similar. Businesses are responsible for charging, collecting, and remitting VAT/GST on their sales, and they can claim credits for the tax they pay on their acquisitions or imports, known as input tax.

Broadly, non-resident entities that import goods into jurisdictions with a VAT system in place will incur VAT or GST at the border. However, given the fundamental principle of VAT systems that the tax is borne by the end consumer, refund mechanisms are typically in place to allow the non-resident entity to recover this once they have registered for VAT or GST in that jurisdiction.

Additionally, export sales of goods and services from a jurisdiction with a VAT system in place are broadly zero-rated, meaning no VAT or GST is charged. These exports may still be subject to the local consumption tax rules of the recipient's jurisdiction, which includes the US where state-level sales taxes may apply. This ensures that taxation is appropriately levied in the country where the goods or services are consumed, maintaining fairness in the global trade system.

The Australian GST system

In Australia, GST is a broad-based tax set at a rate of 10 per cent. It applies to most goods and services sold or consumed within the country. Similar to all other VAT systems, the GST is designed to ensure that the tax is only paid once by the end consumer, and businesses can recover any GST paid on business-related purchases or importations.

GST will only apply to supplies of goods and services that are ‘connected with Australia’ by an entity that is or is required to be registered for GST. Additionally, the supply must be for consideration (such as money), and be made in the course of the entity's enterprise. This applies to Australian resident entities and foreign entities, creating a level playing field for suppliers in the Australian market.

Entities may register for GST in Australia voluntarily or will be required to do so when the Australian threshold of AUD 75,000 is reached in a 12-month period. Again, this applies to both resident and non-resident businesses. Once registered, entities will need to charge and collect GST on Australian supplies but can also recover any GST paid on their acquisitions.

Comparison with US sales tax

The US operates a different system known as sales tax, which is levied at the final point of sale to the consumer. US sales tax is not a federal tax, with 45 US states operating their own sales tax regime ranging from 2.9 per cent to 7.25 per cent, creating a complex compliance landscape for US and non-US businesses trading across state lines.

Sales tax is charged by state and local authorities and is administered by the merchant. A merchant must charge sales tax if it has a 'nexus' in the state, which can be based on an economic or physical presence. Compliance involves varying rules across 45 states, each with its own requirements for registration, reporting, and payment.

Despite some differences, the principles are similar to VAT systems globally; the tax is ultimately borne by the end consumer, and resident and non-resident businesses caught within the tax remit are responsible for collecting and remitting the tax.

VAT systems and tariffs: Are they similar?

VAT systems apply equally to domestic and foreign suppliers for all goods and services captured within the local system. This ensures a level playing field, as both domestic and foreign businesses are subject to the same tax rules.

In Australia, GST registration is required when an entity’s activities are captured within the Australian GST rules, or may be made voluntarily where the entity conducts an enterprise in Australia. This allows registered entities, including non-residents, to recover any Australian GST incurred in making their supplies, such as on importation. This mechanism ensures that businesses are not unduly burdened by double taxation and can operate competitively in the Australian market.

In contrast, tariffs are specifically designed to protect domestic industries by making imported goods more expensive, in addition to being applied to exert political pressure on foreign countries.

This clear distinction between VAT systems and tariffs is set out below. 

Aspect VAT Systems Tariffs
Application  
Applied at each stage of the supply chain within the local VAT system.  
Applied on imported goods at the border.  
Purpose  
To impose a tax on consumption by the end consumer and generate revenue for the government.  
To protect domestic industries and generate revenue for the government.  
Impact on prices  
Increases the price of goods and services for consumers by a set rate.  
Increases the price of imported goods and their associated products for both businesses and consumers.  
Responsibility  
Registered businesses charge, collect, and remit the tax. Refund mechanisms allow these businesses to recover VAT/GST incurred.  
Importers pay the tariff at the border. There is typically no refund mechanism.  
Global trade  
Applies equally to domestic and foreign suppliers, ensuring a level playing field for all suppliers. Does not apply to goods and services consumed in a foreign jurisdiction.  
Can create trade barriers and affect international trade. Raises prices of goods that rely on the imported product.  


Understanding the fundamentals of VAT systems is crucial in dispelling misconceptions about their impact on international trade, particularly in the context of reciprocal tariffs. These taxes are designed to be equitable and transparent, applying equally to all businesses operating within a jurisdiction.

Given consumption taxes are intended to be incurred by the end consumer, while tax leakage does occur, VAT systems broadly maintain fairness in global context and do not create disadvantages specifically targeted at US corporations. As such, reciprocal tariffs imposed by governments based on the premise of VAT being similar to tariffs may result in negative consequences for international trade and economic relations.
