E-commerce VAT in Estonia — OSS, IOSS, Amazon FBA & Shopify for OÜs
An Estonian OÜ selling physical goods to EU consumers — via Shopify, WooCommerce, Etsy, or Amazon FBA — hits three VAT regimes at once: domestic 24% Estonian VAT, the EU-wide One-Stop Shop (OSS) for cross-border B2C distance sales, and the Import One-Stop Shop (IOSS) for low-value consignments from outside the EU. Getting the right scheme in place before the €10 000 distance-selling threshold is crossed keeps you on a single quarterly OSS return instead of five national VAT registrations.
The €10 000 distance-selling threshold and OSS
Since 2021-07-01 the old per-country distance-selling thresholds are gone. A single EU-wide €10 000 annual threshold covers B2C cross-border goods and digital services combined; below it, you charge home-country (Estonian) VAT; above it, the place of supply shifts to the buyer’s country. OSS lets a single Estonian registration cover all other 26 EU states through one quarterly declaration to EMTA.
Practical rules per EMTA’s special-schemes page: register for OSS in Estonia before the first cross-border sale that takes you over €10 000; file quarterly by the end of the month following the quarter; pay in euro; keep records for 10 years. If you cross the threshold mid-quarter, the OSS rate applies from the sale that crossed it, not from the next quarter.
IOSS, the €150 rule, and imports
IOSS applies to B2C imports of goods whose intrinsic value (excluding shipping and insurance) does not exceed €150. With IOSS, VAT is charged at checkout at the destination-country rate and remitted monthly via a single EU portal; without it, the customer pays VAT and a broker fee at import — a conversion-killer. IOSS registration is done in one EU state (Estonia is fine for OÜs) via EMTA.
Above €150 the regular import-VAT regime applies: VAT and any duty are settled at customs by the importer of record. Marketplaces (Amazon, eBay, AliExpress) running the “deemed supplier” rule may collect IOSS VAT themselves on your behalf — confirm in Seller Central whether Amazon is taking that role for your SKUs before you register redundantly.
Amazon Pan-EU FBA — the multi-registration trap
Pan-EU FBA distributes your stock across Amazon fulfilment centres in up to 7 EU countries (DE, FR, IT, ES, PL, CZ, NL and rotating). Every country where Amazon stores your goods creates a VAT-registration obligation locally, independent of OSS — because OSS only covers B2C cross-border supplies, not local-to-local supplies from foreign stock. FBA Baltic-only (EE/LT/PL, for example) is materially cheaper than full Pan-EU once you count 5–7 foreign VAT filings.
Q: Do I need OSS registration for my Estonian Amazon FBA store? A: Yes — OSS handles all cross-border B2C shipments from your stock, including Amazon-fulfilled orders. But OSS does NOT replace the local VAT registrations that Pan-EU FBA triggers in each fulfilment-centre country; you end up running OSS plus those national VAT numbers in parallel. We model the break-even for Baltic-only vs. Pan-EU FBA before onboarding.
Q: How do I declare VAT on Amazon returns from an Estonian OÜ? A: Returns that reverse a cross-border B2C sale are corrected in the OSS return of the quarter they occur (EMTA form), reducing output VAT for that destination country; returns on locally-fulfilled supplies (Pan-EU FBA) are corrected in the relevant national VAT return. Amazon’s VAT Transactions Report is the source of truth; we reconcile it to Merit/Xero monthly.

Do I need OSS registration for my Estonian Amazon FBA store?
If your cross-border B2C sales inside the EU exceed €10,000 a year, OSS lets you declare VAT in a single filing instead of registering in each destination country. Pan-EU FBA usually crosses that threshold quickly and can also trigger standalone VAT registrations in the countries where Amazon warehouses your stock. We map Seller Central reports to OSS versus standalone registrations during onboarding.
