What you need

Your VAT number and OSS registration

The number that matters is €10,000. Below it, an EU-based store can charge its own country's VAT rate on sales to consumers anywhere in the EU. Above it, a Dutch store selling a jacket to a customer in Germany has to charge German VAT, and a sale to Belgium needs Belgian VAT. Without OSS, that would mean registering for VAT in every one of those countries. With it, you file one return in your home country and pay the total there.

I set this up for Dutch and other European Shopify stores, and most of the problems I see come from the Shopify side rather than the tax office: the wrong registration type, a missing tax service, or IOSS switched on next to OSS. This guide covers both. The rules come from the European Commission and the Dutch Belastingdienst, and the Shopify steps from Shopify's Help Center, all as checked on 7 November 2026.

What OSS is, in plain terms

OSS stands for One-Stop Shop. Since 1 July 2021, it has covered distance sales of goods between EU countries and certain services to consumers. You register in one EU country, called your Member State of identification, and report VAT for all the other EU countries in one return there. That country passes the money on to the others.

Three points trip people up:

• It's only for sales to consumers. Sales to VAT-registered businesses in other EU countries normally fall under the reverse charge and stay out of OSS.
• It doesn't replace your normal VAT return. Sales in your own country still go on your domestic return. OSS covers the cross-border consumer sales.
• Once you join, it covers everything in scope. The European Commission says that when you opt in, the scheme applies to all your relevant sales in all EU countries. You can't use it for Germany and register locally for France for the same kind of sale.

The three schemes, and which one is yours

Most Shopify stores based in the Netherlands, Belgium or any other EU country that ship from their own warehouse need the Union scheme. A UK or US store that ships parcels directly to EU consumers is usually looking at IOSS instead. Non-EU businesses can also use the Union scheme for goods already inside the EU, for example stock held in an EU fulfillment center, which is a question for your accountant.

Do you need OSS yet?

The €10,000 threshold is one figure for the whole EU, not per country. It counts your cross-border sales of goods to consumers in other EU countries, plus certain digital services, excluding VAT, in the current and the previous calendar year. It only applies to businesses established in a single EU country.

Below the threshold, Shopify calls this the micro-business exemption: you keep charging your home VAT rate on cross-border sales and report them on your normal return. If you use Shopify Tax, Settings > Taxes and duties > European Union shows whether each registration is below, approaching or over a threshold, and Shopify sends monthly notifications about possible liabilities.

How to register for OSS in the Netherlands

Every EU country runs OSS through its own tax office. For a Dutch business, that's the Belastingdienst:

1. Log in to Mijn Belastingdienst Zakelijk with your business login.
2. Go to btw > E-commerce > Registratie and register for the Unieregeling (or the Invoerregeling if you import goods of €150 or less).
3. Wait for approval. Under the Unieregeling you can start from the first day of the quarter after you register. Invoerregeling users get a separate IOSS number.
4. Note your start date and tell whoever handles your bookkeeping, because sales from that date onward go on the OSS return, not the domestic one.

In other EU countries the steps are similar but the portal differs. Your accountant or local tax office will know where to register.

How to set up OSS in Shopify, step by step

Do this once your OSS registration is confirmed, or on the day you cross the threshold if your registration is still being processed.

1. Check your tax service. OSS only works with Shopify Tax or Basic Tax. Basic Tax is only available in the EU for stores already collecting tax there before 13 May 2026, so most new stores use Shopify Tax. With manual tax settings you'd have to maintain every country's rate yourself.
2. Check your EU location and shipping. In Settings > Locations, confirm your warehouse is listed with its EU address. In Settings > Shipping and delivery, make sure you have an EU shipping zone, because the EU tax region appears once you do.
3. Add your home registration. Go to Settings > Taxes and duties > European Union. Under Collect VAT in an EU country, click Collect VAT, select your country and enter your VAT number. This covers sales to customers in your own country.
4. Add the OSS registration. Under Collect VAT cross-border, click Collect VAT, select Collect using a One Stop Shop (OSS) registration, choose the country where you registered for OSS, enter your VAT number and click Collect VAT.
5. Check prices. If you show VAT-inclusive prices, check how prices behave in each market. With one price for all EU customers, your margin changes with each country's rate.
6. Test an order. Create a draft order to a customer in another EU country with a shipping method selected, and check the tax line uses that country's standard rate.

Still below the threshold? In step 4, choose Collect using your home country registration instead. That's the micro-business option, and Shopify charges your home rate on cross-border sales.

IOSS for stores shipping from outside the EU

If your stock sits in the UK, the US or elsewhere outside the EU, OSS isn't the scheme for those parcels. IOSS lets you charge VAT at checkout on consignments of €150 or less, so the customer doesn't pay import VAT on delivery. Sellers outside the EU usually need an EU-based intermediary to use it, and IOSS returns are monthly.

Three Shopify rules matter here:

• OSS and IOSS can't run together. When OSS is in use, Shopify disables IOSS collection on orders shipped from outside the EU. If you have locations both inside and outside the EU, Shopify recommends OSS.
• IOSS and Shopify's duties feature are exclusive at checkout. If you activate duties and import taxes for the EU, that feature handles all EU taxes and your IOSS registration is no longer used at checkout.
• Duty on low-value parcels changed on 1 July 2026. Shopify's guidance says the EU began removing the €150 customs duty exemption, with a flat €3 duty per tariff code in a parcel, not per parcel. VAT rules didn't change. Add HS codes under each product's Shipping > Customs information so duties calculate properly.

Filing and paying the OSS return

For the Dutch Unieregeling, the Belastingdienst says the return and payment must arrive by the last day of the month after each calendar quarter. You can't file before the quarter has ended.

• File even when there's nothing to report. A return is required for a quarter with no OSS sales. Miss three consecutive quarters and the Belastingdienst excludes you from the scheme for 2 years.
• Pay on time. Three consecutive reminders that aren't paid within 10 days also lead to a 2-year exclusion.
• One payment, in €. You report and pay in € in one payment covering all countries. If you sold in another currency, convert at the European Central Bank rate for the last day of the period.
• Keep records for 10 years. OSS records must be kept for 10 years after the end of the year of the sale, longer than the usual 7, and provided digitally if asked.
• Corrections. Fix a mistake in an earlier quarter through the tax office of the country where you filed.

Common mistakes

• Waiting until the end of the year. The threshold counts as you go. Once you pass €10,000, the next cross-border sale needs the customer's local VAT.
• Using manual tax settings. OSS in Shopify needs Shopify Tax or Basic Tax. Manual rates for 27 countries go out of date.
• Putting OSS sales on the domestic return. They go on the OSS return. Only sales to customers in your own country stay on the domestic one.
• Running IOSS next to OSS. Shopify won't support both, so pick the one that fits where your stock ships from.
• Skipping nil returns. Three missed quarters means 2 years out of the scheme.
• Forgetting B2B customers. Business sales with a valid VAT number in another EU country are normally reverse-charged and stay out of OSS.
• Pricing with your home rate in mind. A VAT-inclusive price earns you less in a country with a higher rate. Check your margins with the profit margin calculator.

OSS checklist for Shopify stores

• Cross-border consumer sales tracked against €10,000 from the first sale of the year.
• Registered for the right scheme in your Member State of identification.
• Shopify Tax (or Basic Tax) active for the EU.
• EU location and EU shipping zone set up.
• Home country VAT number added under Collect VAT in an EU country.
• OSS registration added under Collect VAT cross-border.
• IOSS off if OSS is on, and duties settings checked for non-EU shipping.
• Draft order tested to at least two other EU countries.
• Quarterly export and filing date in the calendar, including nil quarters.
• Records kept for 10 years.
