Your product costs €29.99 everywhere in the EU – one price, one listing, nice and clean. Your profit, however, does not respect that uniformity: on an order from Germany, €4.79 of VAT sits inside the price; on the identical order from Hungary, it is €6.38. Roughly €1.58 of margin per sale evaporates – with purchasing, shipping and fees unchanged.

The mechanism is called the destination principle, and since the EU’s 2021 reform it affects virtually every seller shipping to consumers in other EU countries. This article explains how it works, when it kicks in, and how to keep its margin impact under control.

The destination principle in one paragraph

For cross-border B2C sales within the EU, the VAT of the country the goods are delivered to applies – not that of the country of dispatch. From a fixed gross price, a different net amount is therefore extracted depending on the destination: €29.99 ÷ 1.19 for Germany, ÷ 1.20 for France, ÷ 1.27 for Hungary. Standard rates span from 17% (Luxembourg) to 27% (Hungary) – ten percentage points that land directly in your margin.

The €10,000 threshold: small but decisive

The destination principle applies once your total cross-border B2C revenue in the EU (goods plus digital services, all countries combined) exceeds the micro-threshold of €10,000 net per year. Below it, you may keep invoicing at your home rate. The threshold is crossed quickly – barely 30 orders of €29.99 a month to other EU countries is enough.

From then on there are two routes: register for VAT in every destination country – or use the One-Stop-Shop (OSS) and report all EU sales in a single return via your home tax authority. OSS simplifies the reporting substantially; calculating correctly per country remains your job. Note also: if you ship from foreign warehouses (Amazon FBA/PAN-EU), local registrations in those countries are still required – details in our guide to VAT in e-commerce.

What the rate does to margin: a worked example

Same product, same gross price €29.99, cost of goods €9.50, marketplace fee €4.50:

Destination	VAT rate	Net proceeds	Profit/unit
Luxembourg	17%	€25.63	€11.63
Germany	19%	€25.20	€11.20
France	20%	€24.99	€10.99
Hungary	27%	€23.61	€9.61

Between the best and worst case lies a good €2 per sale – about 17% of profit. Making it worse: marketplaces calculate their commission on the gross price. The fee stays identical in every country even as your net proceeds shrink – the tax effect hits your margin exclusively, never the marketplace’s.

Three pricing strategies for dealing with it

Uniform price, floating margin. Simplest to run, most consistent for conversion – but high-margin countries subsidise the weak ones. Works as long as the worst-case country (27%) is still profitable.

Country-specific prices. Maximum margin control, but operational overhead across listings and ads – and only partially feasible on some marketplaces.

Hybrid. A uniform base price with surcharges only for high-VAT countries with relevant volume. In practice the most common compromise.

Which strategy holds up is decided by the numbers per country – not by gut feeling.

Quantify instead of guessing

That is exactly what we built the free E-Commerce Profit & VAT Simulator (OSS) for: enter gross price, cost of goods and fees, pick destination countries – the simulator shows net proceeds and profit per country side by side. You see at a glance which country carries your margin and where a surcharge would be needed. For the building blocks, see our guides to calculating gross and net correctly and – for Amazon sellers – the fee breakdown.

Conclusion: OSS files the return, the maths stays yours

The One-Stop-Shop centralised the reporting, but the business task remains: knowing, per country, what is left of the price. With the Profit & VAT Simulator you quantify the effect in a minute.

In daily operations, that logic then has to run automatically for every order: detect the destination, apply the rate, book the net amount cleanly. That is precisely what KudTax does – across all shops and marketplaces, including a booking-ready DATEV export for your tax advisor. The destination principle becomes a background calculation instead of a month-end project.
