In the rapidly changing realm of cross-border eCommerce, complying with VAT requirements and customs procedures can sometimes prove to be a big headache, particularly for companies shipping products into the European Union (EU). The Import One-Stop Shop (IOSS) scheme has alleviated a much-needed convenience for VAT administration on low-value goods. However, how exactly does it co-exist with customs declarations? Can it eliminate them, or do both continue to coexist?
In this blog, we’re going to clear up the connection between IOSS and customs declarations. We’ll break down how they work hand in hand and explain why it’s so important to grasp both of these concepts for hassle-free, compliant deliveries throughout the EU.
What is IOSS?
The Import One-Stop Shop (IOSS) is a special VAT scheme introduced by the EU on 1 July 2021 to simplify VAT collection on distance sales of goods valued under EUR 150 imported from non-EU countries.
Here’s what IOSS allows sellers to do:
- Collect VAT at the point of sale (i.e., when the customer pays).
- Declare and pay the VAT monthly through a single IOSS return.
- Use one IOSS registration to cover all 27 EU member states.
By doing this, customers are no longer charged VAT upon delivery, which improves the buying experience and reduces delivery delays.
What are Customs Declarations?
A customs declaration is a formal statement that provides information about goods entering a country. It is required for customs authorities to assess the legality, origin, classification, and applicable duties or taxes of the goods.
For goods shipped into the EU, customs declarations are mandatory regardless of the value of the shipment or whether the seller uses the IOSS scheme.
Key elements of a customs declaration typically include:
- Sender and recipient details
- HS (Harmonized System) codes for goods
- Country of origin
- Description and quantity of goods
- Invoice value
- IOSS number (if applicable)
IOSS vs. Customs Declarations: What’s the Difference?
IOSS and customs declarations serve two different purposes:
- IOSS is about VAT: It handles the tax that’s collected from the customer at checkout.
- Customs declarations are about border control: They ensure that goods meet legal import requirements and help customs authorities verify compliance.
So, does IOSS replace customs declarations?
No, it doesn’t.
Even when a seller uses IOSS, a customs declaration must still accompany the shipment into the EU. The key difference is that when the IOSS number is provided in the declaration, customs authorities can see that VAT has already been paid.
How IOSS Affects the Customs Declaration Process
The customs process becomes simpler and faster when the IOSS number is used correctly. Here’s how it works:
- Sellers charge VAT at checkout (through their online store or marketplace).
- Seller includes the IOSS number in the customs declaration.
- The carrier or customs system recognises the IOSS number and confirms that VAT has been prepaid.
- The shipment is released faster and is exempt from additional VAT or handling fees at delivery.
Without IOSS, the customer may have to pay VAT upon delivery, plus extra admin charges from the courier, which often leads to poor customer experience, delays, and even parcel refusals.
Common Mistakes and Pitfalls
Even with IOSS, problems can arise if customs declarations are not filled out correctly. Some common issues include:
Omitting the IOSS Number
If the IOSS number is not entered into the appropriate field (usually box 44 of the customs declaration), customs won’t know that VAT was prepaid. This results in double taxation or delivery delays.
Misclassification of Goods
Incorrect HS codes or vague descriptions can lead to customs questioning the value or eligibility for IOSS, which complicates the clearance process.
Not Using the Right Shipping Partners
Some couriers or customs brokers may not be equipped to handle IOSS-linked shipments properly. It’s essential to work with logistics providers who understand IOSS protocols.
