International VAT & OSS for Foreign Companies
Find International VAT and OSS support in Greece for foreign companies selling into Greece and across the European Union.
N. KOLYDAS I.K.E. supports foreign businesses with VAT route selection, Greek VAT registration review, Union OSS / Non-Union OSS assessment, IOSS review, marketplace VAT analysis and cross-border VAT compliance coordination. The purpose is to choose the correct VAT route before filings, registrations or platform reporting create unnecessary risk.
Goods, services, B2B, B2C, platforms, marketplaces, imports and countries involved.
Greek VAT registration, OSS, IOSS, foreign VAT registration or combined structure.
VAT route selection should be made before deadlines, filings and platform corrections.
Registration, compliance coordination, platform data review and recurring VAT support.
Cross-border VAT should start with the correct structure.
Many international businesses assume that one VAT registration or one OSS setup will solve everything. In practice, the correct route depends on the type of supplies, where customers are located, where goods move from, whether platforms are involved and whether local obligations still apply.
What this service does
We help foreign companies understand whether they need a Greek VAT number, an OSS route, an IOSS route, a local registration elsewhere in the EU, or a combined compliance structure.
- Greek VAT registration review for foreign companies.
- Union OSS and Non-Union OSS route assessment.
- IOSS review for imported e-commerce transactions under applicable rules.
- Marketplace, platform and mixed sales model review.
- Cross-border VAT structure and reporting logic.
- Ongoing VAT coordination for international operations.
Designed for foreign companies that need clarity before they expand, invoice or file.
This service is appropriate when the business knows there is a VAT issue but does not yet know which route is commercially and technically correct.
E-commerce businesses
Companies selling goods to private customers in Greece or across multiple EU countries through their own website or digital channels.
Cross-border service providers
Businesses supplying B2C or mixed services and needing clarity on VAT treatment, reporting route and invoicing logic.
Non-EU businesses
Companies outside the EU that need a practical route for EU consumer sales, imported goods or wider VAT compliance coordination.
Marketplace sellers
Businesses selling through online marketplaces or platforms and needing clarity on who carries VAT obligations in each scenario.
Growing international groups
Companies expanding into Greece or the EU that want their VAT framework reviewed before operational scale creates problems.
Businesses with mixed flows
Cases involving more than one country, more than one sales model, or a combination of domestic and cross-border transactions.
A structured VAT entry point, not a generic information page.
We focus first on route selection and then on the correct implementation path: registration, OSS/IOSS review, platform reporting logic or recurring VAT compliance.

VAT registration, OSS, IOSS or another route?
Not every international seller should be pushed into the same compliance path. The correct route depends on the actual transaction model.
Decision point 01
Greek VAT Registration or OSS?
Used where the business may have local Greek VAT obligations or qualifying cross-border consumer transactions.
Greek VAT registration may be appropriate where the business has a local Greek VAT footprint, domestic reporting needs, Greek operational activity or a structure that must be handled through Greece. OSS may be relevant where qualifying cross-border consumer transactions can be reported through the appropriate OSS framework.
- Review where goods or services are supplied.
- Review whether customers are businesses or consumers.
- Review whether domestic Greek VAT obligations remain relevant.
Decision point 02
OSS or local VAT registration in another EU country?
Used where a business sells into multiple EU countries and needs a reporting route.
OSS may simplify certain reporting obligations, but it does not automatically remove every local VAT obligation. The transaction model, stock location, fulfilment route, customer location and marketplace role must be reviewed before choosing the route.
- Review whether goods are stored in an EU country.
- Review whether the seller has local domestic supplies.
- Review whether platform or marketplace rules change the VAT position.
Decision point 03
IOSS or import VAT handling?
Used for imported e-commerce goods where low-value import rules may be relevant.
IOSS may be relevant for qualifying distance sales of imported goods into the EU, generally within the low-value goods framework. It should be reviewed carefully together with marketplace, logistics, customs and customer data.
- Review whether goods are imported from outside the EU.
- Review consignment value and product type.
- Review whether the platform or seller is responsible for VAT handling.
Decision point 04
Marketplace liability or seller liability?
Used where platforms, online marketplaces or mixed sales channels are involved.
Marketplace and platform rules can change the VAT reporting responsibility. A seller that uses both its own website and marketplaces may need separate logic for each channel.
- Review marketplace reports and seller dashboards.
- Review who collects VAT from the customer.
- Review whether the platform is treated as a deemed supplier in a specific flow.
From uncertainty to the correct VAT route.
The process is designed to move the client from an unclear VAT position to an actionable compliance route without unnecessary delay.
Initial transaction review
We review the business model, type of supplies, customer profile, movement of goods or services and countries involved.
Route selection
We identify whether the case points toward Greek VAT registration, OSS, IOSS, another local registration or a tailored structure.
Implementation planning
We define the practical next step, required information and correct service path for the matter.
Execution and support
Where appropriate, we continue with registration support, compliance handling, ongoing coordination or advanced VAT advisory.
This service connects directly with VAT / OSS pricing.
The service page explains the scope. The pricing page shows the indicative starting fees and how the service is positioned in the wider international business catalogue.
Indicative starting fees
VAT Treatment Review may start from €450 + VAT. OSS / Cross-Border VAT Review may start from €600 + VAT. VAT Registration in Greece for foreign companies may start from €750 + VAT.

- Historic corrections, amended returns, retrospective platform reconciliations or tax authority communication.
- Legal opinions, binding tax rulings, litigation, audit defence or regulated legal advice.
- ERP, Shopify, marketplace, invoicing software or checkout implementation work.
- Translation, legalisation, government fees, bank fees or third-party service provider fees.
- Ongoing VAT filing, OSS filing, VIES, Intrastat or myDATA reconciliation unless included in the proposal.
Connect VAT route selection with the right business service in Greece.
