IOSS Explained: What It Covers, What It Misses, and When D2C Brands Outgrow It
IOSS simplifies VAT collection on low-value shipments into the EU. It does not replace VAT registration, does not cover goods over €150, and does not handle customs duties.
What IOSS Actually Does
The Import One Stop Shop (IOSS) is an EU VAT registration scheme that lets non-EU sellers collect VAT from EU customers at checkout, remit it via a single monthly return, and have goods clear customs without an import VAT charge at the border.
Before IOSS, every low-value parcel entering the EU was either exempt from VAT (under the old €22 de minimis) or required the buyer to pay VAT on delivery. IOSS removed the exemption and created a cleaner mechanism: sellers collect VAT upfront, declare it centrally, and goods clear faster.
What Happens at Each Step Under IOSS
IOSS changes who pays VAT and when. The key shift is that import VAT is no longer assessed at the border because the seller already collected it from the customer.
IOSS handles import VAT only. Customs duties (tariffs) are assessed independently based on the product’s HS code and country of origin. Most consumer goods under €150 fall below the duty de minimis, but some categories do not.
What IOSS Does Not Cover
IOSS is genuinely useful for D2C brands shipping small orders directly from outside the EU. It has hard limits that catch scaling brands off guard.
| Scenario | Does IOSS apply? | What is needed instead |
|---|---|---|
| Single order over €150 intrinsic value | Not eligible | Standard import with customs duties and import VAT at border. Requires an IOR. |
| Selling from EU warehouse stock | Not applicable | Goods already in EU. Standard VAT registration in each country where stock is held, or OSS for cross-border B2C. |
| B2B sales to EU businesses | Not applicable | IOSS covers B2C only. B2B requires standard VAT registration and reverse charge handling. |
| Marketplace sales (Amazon, Zalando) | Platform handles it | Amazon EU is an IOSS-registered marketplace and handles IOSS for third-party sellers. Do not use your own IOSS number. |
| Excise goods (alcohol, tobacco) | Excluded | Excise goods are explicitly excluded from IOSS regardless of value. |
| Customs duties on dutiable categories | Not covered | IOSS covers VAT only. Duties are assessed separately at the applicable tariff rate. |
Some sellers try to split orders above €150 into multiple consignments to stay under the threshold. EU customs authorities treat artificially split shipments as a single consignment. The practice is considered VAT avoidance and carries significant penalty risk.
How to Register for IOSS as a Non-EU Seller
Non-EU sellers cannot register for IOSS directly in most EU member states. They must appoint an EU-established intermediary who registers on their behalf and takes joint liability for VAT compliance.
The intermediary requirement adds cost and a layer of dependency. If an intermediary terminates the relationship, the non-EU seller’s IOSS registration lapses and shipments begin attracting import VAT at the border until a new intermediary is appointed and a new registration is live. There is no grace period.
No mutual assistance agreement exists between the EU and the US or UK. Brands from both countries must appoint an EU intermediary. This is not optional.
When IOSS Is Right and When It Is Not
The right VAT structure depends on average order value, whether you hold EU stock, and your channel mix.
| VAT mechanism | Best suited for | Key limitation | IOR required? |
|---|---|---|---|
| IOSS | D2C, orders consistently under €150, shipping direct from outside EU | Hard €150 cap. Intermediary dependency. Does not cover in-EU stock. | Yes, on every shipment |
| OSS (One Stop Shop) | Brands with EU warehouse stock selling B2C across multiple member states | Covers intra-EU sales only. Requires existing EU VAT registration. Does not cover imports. | No (goods already in EU) |
| Country VAT registrations | Brands exceeding thresholds, B2B sellers, fiscal rep countries (France, Spain) | Per-country admin. Fiscal rep required in several EU states for non-EU brands. | Depends on supply chain |
| EuroSOR structure | Brands with mixed order values, EU stock, marketplace sales, and B2B | Better suited to brands moving real volume. Not a self-service setup. | Included within structure |
IOSS works well when:
- Orders are consistently under €150
- You ship direct from outside the EU, not from EU stock
- Sales are B2C only
- You are not on Amazon EU (they handle IOSS themselves)
- Volume is manageable through a single intermediary
IOSS becomes a problem when:
- Average order value approaches or exceeds €150
- You start storing stock in an EU warehouse
- You add B2B customers to your EU channel mix
- You list on Amazon EU (your IOSS number conflicts with theirs)
- Your intermediary raises prices or exits the market
When you grow past IOSS, EuroSOR handles the full structure.
IOSS solves a specific problem for early-stage D2C. As order values, channels, and EU stock locations grow, VAT compliance needs a more complete operating structure. EuroSOR covers IOSS alongside IOR, country VAT registrations, fiscal rep obligations, EPR, and marketplace compliance under one contract.
| VAT obligation | IOSS only | EuroSOR structure |
|---|---|---|
| D2C imports under €150 | Covered. Monthly IOSS return via intermediary. | Included. EuroSOR acts as intermediary or manages within broader VAT structure. |
| Orders over €150 | Not covered. Import VAT assessed at border. Requires separate IOR. | Covered. EuroSOR acts as IOR on every shipment regardless of value. |
| EU warehouse stock (OSS / local VAT) | Not applicable. IOSS does not cover intra-EU movements. | Covered. VAT registrations and OSS filings managed within structure. |
| Fiscal rep (France, Spain, Italy) | Not covered. IOSS does not affect fiscal rep requirements. | Handled within EuroSOR. No separate fiscal representative needed. |
