The Difference Between VAT, Sales Tax, and Customs Duties

What makes these taxes different and why it matters for international trade?

For companies engaged in cross-border trade, an understanding of taxes is a must, but one that normally tends toward confusion. 

Many companies use the terms VAT, sales tax, and customs duties interchangeably. In reality, these taxes are fundamentally different in the way they are applied, collected, and finally, are paid. 

This article explains various tax types and underlines the key differences between them. Understanding these taxes will help any international seller or expanding vendor to stay compliant and avoid expensive surprises.

What is Value Added Tax?

VAT is a form of indirect tax levied on each stage of manufacture from production through the supply chain to final sale to the consumer.  

  • Common in: EU, UK, Canada, Australia 
  • Levied on: both domestically produced and imported goods/services
  • Paid by: An end consumer, charged at every stage of the supply chain 
  • Refundable? Yes, businesses registered for VAT can reclaim VAT

Key features: 

  • Tax is levied on added value at each stage along the supply chain 
  • Businesses collect VAT on their sales (output VAT) and reclaim the input VAT paid on their purchases 
  • Ultimately, the end consumer bears the burden of the tax

What is a Sales Tax?

Sales tax is also an indirect tax, but it is levied only at the last point of sale to a final consumer. 

  • Common in: USA 
  • Levied on: Only retail sales 
  • Paid by: The end consumer 
  • Refundable? No 

Key features: 

  • Collected singularly at the retail level 
  • Manufacturers and wholesalers do not normally pay sales tax 
  • Sellers commonly have to discount resale certificates to insulation business buyers 

What are Customs Duties?

They are taxes imposed against the importation of goods into a country. Custom duties are meant for protecting the domestic industries and generating revenue for the government.  

  • Common in: all countries apply in some capacity customs duties 
  • Levied on: Imported goods on customs clearance 
  • Paid by: The importer of record 
  • Refundable? No 

Key features: 

  • Calculated based on HS code, declared value, origin, and shipping costs. 
  • Vary depending on type of product, country of origin, and trade agreements. 
  • May be accompanied by tariffs, which are policy-based kinds of duties.

 Do I have to pay all three?

Yes, in many cases, businesses must both customs duty and VAT be imposed on the imported goods. And if you happen to sell in a state where sales tax applies (e.g., the US), you may have to collect sales tax at checkout rather than charging VAT. 

Generally speaking: 

  • Importing into the EU, customs duties + import VAT are imposed at the border. 
  • Selling to a US customer might require you to collect sales tax, depending on the state. 

Being aware of where-and-how these apply will help you set-up your pricing, compliance, and logistics right. 

Why this matters for international trade

These differences between VAT, sales tax, and customs duties help you and your business: 

  • Avoid surprise costs and shipping delays. 
  • Select the right Incoterms and assign tax responsibility properly. 
  • Ensure compliance with import/export and local tax laws. 
  • Reclaim VAT where possible to further reduce costs.
