OSS VAT return preparation for EU sellers, without the quarterly spreadsheet.

Your OSS VAT return, country by country, from the sales export you already have.

Import a Shopify, WooCommerce, Amazon or Stripe CSV. We apply the destination-country rate to every line and show the per-country breakdown in the OSS portal's format. Every rate applied is logged. You or your accountant file the return.

Sounds familiar?

• Twenty-seven member states, each with its own standard and reduced rates by product category, and a quarter of orders to classify.
• My shop exports orders, not a filing-ready breakdown per member state. Every quarter I rebuild it in a spreadsheet.
• My accountant bills a monthly package and still asks for my per-country spreadsheet before every return.
• Reduced rates changed in eleven member states on 1 January 2026. Nothing in my export tells me which lines are affected.

How it works

1. 01

   Import sales

   Upload a CSV from Shopify, WooCommerce, Amazon or Stripe. Map the columns once; the mapping is saved for next quarter.

2. 02

   Check the classification

   Each line gets a destination country and a rate, with the rate table version and source shown. Fix exceptions in a review screen.

3. 03

   Export the return

   Per-country totals in the OSS portal's format, ready for you or your accountant to file, plus an audit trail PDF of every rate applied.

What you get: A per-country OSS breakdown in your national portal's format, with an audit trail of every rate applied.

Who it is for

EU sellers above the €10,000 cross-border B2C threshold, sellers whose provider stopped filing OSS returns this year, and small accounting firms with e-commerce clients.

Not for sellers whose marketplace collects VAT on all their sales, nor for IOSS (imports up to €150, monthly return) at launch.

Pricing

No VAT is charged (French micro-entrepreneur, art. 293 B CGI). The Seller plan is also available at €99 per quarter.

Questions

Do you file the return?

No. You get the per-country breakdown in the portal's format and submit it yourself or hand it to your accountant. Direct filing depends on each member state's portal and is not in v1. The OSS itself is extended on 1 July 2028 under ViDA; we will follow that change.

When is the OSS return due?

Quarterly, by the end of the month after the quarter: 30 April, 31 July, 31 October and 31 January. The deadline does not move when it falls on a weekend or public holiday. A nil return is still required for a quarter with no sales.

Does the €10,000 threshold apply per country?

No. It is EU-wide, excluding VAT, and measured over the current and the previous calendar year. Once you pass it, destination-country VAT applies to every cross-border B2C sale.

How are rates kept current?

The rate table is maintained from the official national rules, and every export shows the version applied. On 1 January 2026 no standard rate changed, but reduced rates or their scope changed in eleven member states. You set a product category once per product; the table maps it to the reduced rate where one exists.

What if I find a mistake after filing?

OSS corrections go into a later return, within three years of the original due date. The audit trail shows which rate and table version were applied to each line, so you know exactly what to correct.

My provider stopped filing OSS returns this year. Can I start mid-year?

Yes. Import the current quarter's sales and you have the breakdown for the next deadline. Earlier quarters can be imported too, so the audit trail is complete. Filing itself stays with you or your accountant.
