IOSS, OSS & VAT Compliance – Sell Across Borders, Comply with Confidence
VAT is the single biggest compliance challenge for cross-border ecommerce. One mistake can mean customs delays, frustrated customers and unexpected tax bills. We make VAT simple—so you can focus on selling, not on paperwork.
VAT Shouldn’t Be a Barrier to Global Growth
Selling to customers across borders should be simple. But VAT rules vary by country, thresholds differ, and customs procedures can delay deliveries by weeks. The EU has simplified cross-border ecommerce VAT with two game-changing schemes: IOSS for imports and OSS for intra-EU sales. But navigating these schemes requires expertise. Our IOSS, OSS & VAT Compliance practice helps you register, file and stay compliant across 30+ countries—so your customers receive their orders on time, and you avoid unexpected tax liabilities.
Complete VAT Compliance Solutions
IOSS (Import One-Stop Shop) – Simplify EU Imports Under €150
The Import One-Stop Shop (IOSS) is a game-changer for businesses selling low-value goods to EU customers. Instead of customers paying VAT and customs handling fees at delivery, you collect VAT at checkout and remit it monthly via a single return.
How IOSS works:
- For goods valued at €150 or less shipped from outside the EU to EU consumers
- You charge VAT at checkout (based on the customer’s country rate)
- You file a single monthly IOSS return covering all EU sales
- Goods clear customs quickly—no delays, no hidden fees for customers
What we cover for IOSS:
- Eligibility assessment: Does your business qualify for IOSS?
- IOSS registration: Choose an EU country of establishment and register
- Marketplace integration: Ensure your sales channels (Amazon, Shopify, etc.) are IOSS-compatible
- VAT calculation and collection: Set up correct VAT rates at checkout
- Monthly filing: Prepare and submit IOSS returns
- Record-keeping: Maintain required documentation for audits
Who needs IOSS:
- Ecommerce sellers shipping low-value goods to EU customers
- Marketplaces facilitating third-party sales to the EU
- DTC brands fulfilling orders from outside the EU
OSS (One-Stop Shop) – Simplify Intra-EU VAT
The One-Stop Shop (OSS) replaces multiple VAT registrations across EU countries with a single quarterly return. If you sell to consumers in multiple EU countries, OSS saves you from registering for VAT in every country where you exceed distance selling thresholds.
How OSS works:
- For B2C sales of goods and services within the EU
- You charge VAT at the rate of the customer’s country
- You file a single quarterly OSS return covering all EU sales
- VAT is paid to your country of registration, which distributes it to other member states
What we cover for OSS:
- OSS eligibility: Determining if OSS is right for your business
- OSS registration: Registering in your EU country of establishment
- Threshold monitoring: Tracking sales to each EU country
- VAT rate application: Ensuring correct rates for each product/country
- Quarterly filing: Prepare and submit OSS returns
- Non-Union OSS: For businesses established outside the EU
Who needs OSS:
- Ecommerce sellers with inventory in the EU
- Digital service providers (software, streaming, SaaS)
- Businesses exceeding distance selling thresholds
EORI Numbers – Your Customs ID for EU Trade
An EORI (Economic Operator Registration and Identification) number is required for any business importing or exporting goods to/from the EU. Without it, your shipments can’t clear customs.
What we cover for EORI:
- EORI application: Registration in the EU country where you first import/export
- UK EORI: Separate registration for Great Britain (post-Brexit)
- EORI validation: Ensuring your EORI is active and correctly linked to your business
- Customs integration: Linking EORI to your IOSS/OSS registration
Fiscal Representation – When You Need a Local VAT Representative
Some EU countries require non-EU businesses to appoint a fiscal representative—a local entity jointly liable for your VAT obligations. We provide or arrange fiscal representation where required.
What we cover for fiscal representation:
- Requirement check: Which countries require fiscal representation
- Representative appointment: Acting as or arranging your fiscal representative
- Joint liability management: Ensuring compliance to protect your representative
- VAT registration and filing: Full management of local VAT obligations
Countries requiring fiscal representation for non-EU businesses:
- Austria, Belgium, Denmark, Finland, Germany, Italy, Netherlands, Portugal, Spain, Sweden, and others (requirements vary)
Direct VAT Registration – When OSS/IOSS Don’t Apply
For some activities, OSS and IOSS aren’t available. This includes B2B sales, goods over €150, and certain services. In these cases, you may need direct VAT registration in individual countries.
What we cover for direct VAT registration:
- Registration threshold analysis: Do you exceed local thresholds?
- Country-by-country registration: Managing multiple VAT registrations
- Local filing: Preparing and submitting periodic VAT returns
- Intrastat and EC Sales Lists: Additional reporting requirements
- Local language support: Dealing with tax authorities in their language
- Deadline management: Never miss a filing deadline
VAT Refunds – Recover VAT Paid Abroad
If your business incurs VAT in EU countries where you’re not registered, you can recover it through the EU VAT refund process or via direct claims. We help you identify and recover VAT you’re entitled to.
What we cover for VAT refunds:
- Eligibility assessment: Which expenses qualify for refund
- EU VAT refund process: Filing claims via your home country portal
- Direct claims: For countries outside the EU refund system
- Documentation: Gathering and submitting required invoices
- Follow-up: Managing claims through to payment
