EU VAT compliance for online sellers has never been static — but 2026 brings a concentration of rule changes, enforcement upgrades, and threshold adjustments that makes the current year an unusually high-stakes compliance moment for Amazon sellers and cross-border e-commerce operators with inventory in Germany, France, and Poland. The One Stop Shop framework that simplified multi-country VAT reporting in 2021 is now being extended, enforcement data-sharing between national tax authorities has matured to the point where inconsistencies between OSS filings and local VAT returns are being identified and followed up routinely, and the platform economy VAT rules introduced under DAC7 are generating new reporting obligations for sellers whose transaction data Amazon and other marketplaces are now submitting directly to EU tax authorities on their behalf.
The consequence for Amazon FBA sellers with pan-European inventory is that VAT compliance errors that passed undetected in 2022 or 2023 — when enforcement infrastructure was still being built out — are increasingly being caught in 2026 through automated cross-checks between marketplace-reported transaction data, OSS quarterly returns, and local VAT registrations in the member states where stock is held. The gap between what Amazon reports to tax authorities about a seller's EU sales and what the seller reports in their own VAT filings is narrowing to zero as the EU's VAT compliance technology infrastructure matures — making the accuracy of every component of the VAT reporting chain a higher-stakes obligation than it was even two years ago.
This guide covers the seven EU VAT rules that online sellers with EU operations must track in 2026: the rules that are changing, the rules that are being more actively enforced, and the compliance infrastructure decisions that determine whether a seller's VAT position in Germany and across the EU is robust enough to withstand the scrutiny that the current enforcement environment applies.
1. OSS Threshold Applies Per EU Total, Not Per Country — and the EUR 10,000 Limit Is Stricter Than It Looks
The One Stop Shop distance selling threshold of EUR 10,000 per calendar year applies to the seller's total B2C cross-border sales across all EU member states combined — not per destination country. A seller with EUR 3,000 in cross-border B2C sales to France, EUR 4,000 to the Netherlands, and EUR 4,000 to Italy has exceeded the EUR 10,000 OSS threshold and must either register for OSS or register for local VAT in each country where their cross-border sales exceed the applicable national threshold. This is the most commonly misunderstood aspect of the OSS framework: sellers who check their sales to any individual country and find them below EUR 10,000 may incorrectly conclude they are below threshold when their aggregate cross-border total has exceeded the limit.
The threshold does not apply to sales from inventory held locally in a member state — those are domestic sales subject to local VAT regardless of value, because the goods are already in the destination country when the sale occurs. For Amazon FBA sellers with stock in German, French, and Polish FCs, sales dispatched from those local FCs to consumers in the same country are domestic transactions not counted toward the OSS threshold. Only sales dispatched from one member state to a consumer in a different member state count toward the EUR 10,000 cross-border total. Mapping cross-border vs domestic FBA sales for OSS threshold assessment separates the domestic and cross-border components of FBA sales by member state, applying the OSS threshold calculation to the cross-border portion only — producing the accurate threshold assessment that sellers attempting to perform the calculation manually from Amazon Seller Central sales reports frequently get wrong because the dispatch country attribution requires FBA inventory location data that the sales report alone does not provide.
2. Local VAT Registration Is Still Required When Stock Is Held in Another Member State
OSS does not replace local VAT registration in member states where a seller holds inventory. This is the most operationally significant VAT rule for Amazon FBA sellers enrolled in Pan-European FBA or European Fulfilment Network — and the most frequently misapplied. OSS covers B2C cross-border sales from one member state to consumers in other member states. It does not cover the intra-community acquisitions (stock arrivals from another EU country) or the domestic sales (sales to consumers in the same country as the stock) that arise when Amazon places inventory in French, Polish, or Czech fulfillment centers on the seller's behalf.
Every member state where Amazon holds FBA inventory belonging to the seller creates a VAT registration obligation in that country: the seller must register for local VAT, submit local VAT returns reporting domestic sales and intra-community acquisitions, and file EC Sales Lists reporting the intra-EU stock transfers that generated the acquisitions. In 2026, national tax authorities in Germany, France, Poland, and the Czech Republic are cross-checking Amazon's DAC7 seller data — which includes the fulfillment center locations where seller inventory is held — against their local VAT registration databases. Sellers identified in Amazon's DAC7 data as having inventory in a country where they have no local VAT registration are receiving registration requirement letters with retroactive filing obligations that reach back to the date the inventory first arrived in that member state. Monitoring FBA inventory locations against VAT registration status tracks the current FBA inventory locations across EU member states and compares them against active VAT registrations — flagging member states where inventory is present without a corresponding VAT registration before the tax authority identifies the gap through DAC7 cross-checking.
3. DAC7 Data Sharing Means Tax Authorities Already Know Your Sales Figures
DAC7 — the EU directive on administrative cooperation in taxation that took effect from January 2023 — requires digital platforms including Amazon to report seller transaction data to the tax authority of the member state where the platform operates, which then shares the data with the tax authorities of the member states where the seller is resident and registered. For Amazon sellers operating in the EU, this means that German, French, Polish, and other national tax authorities receive annual reports from Amazon containing each seller's transaction count, gross revenue by member state, and the personal or business identification data that links the Amazon account to the seller's VAT registration.
The practical compliance implication of DAC7 data sharing is that tax authorities are comparing Amazon's reported seller revenue figures against the seller's own VAT return filings — identifying discrepancies between the sales that Amazon reports and the sales that the seller declares. Sellers who have been underreporting EU sales, filing OSS returns that do not capture all cross-border transactions, or omitting domestic sales from local VAT returns in countries where their inventory is held are now exposed to systematic cross-checking that was not technically feasible before DAC7 data sharing was operational. The 2026 enforcement cycle is the third year of DAC7 reporting, meaning national tax authorities have three years of seller transaction data to cross-reference — sufficient historical data to identify multi-year underreporting patterns rather than isolated single-year discrepancies. VAT reporting accuracy in the DAC7 enforcement environment aligns the transaction data that feeds OSS returns and local VAT filings with the Amazon sales data that DAC7 reporting provides to EU tax authorities — eliminating the discrepancies between seller-reported and platform-reported figures that DAC7 cross-checking identifies as the starting point for VAT investigation.
4. OSS Quarterly Returns Must Match Local VAT Returns — the Cross-Check Is Now Automated
OSS quarterly returns filed in the seller's member state of registration (typically Germany or the member state of the 3PL) are shared by the registration member state's tax authority with every destination member state's tax authority — allowing each country to verify that the OSS-reported VAT for sales to their consumers matches the VAT that the local tax authority expects based on transaction data from DAC7 and other sources. In 2026, this cross-check is automated in Germany, France, and the Netherlands: the OSS return data and the DAC7 Amazon transaction data are processed through a matching system that flags discrepancies above a de minimis threshold for human review and potential audit.
The specific inconsistencies that the automated cross-check identifies most frequently are: OSS returns that apply the wrong destination country VAT rate (using the German 19 percent rate for sales to France where 20 percent applies, for example); OSS returns that omit transaction categories that should be included (digital services sold to EU consumers outside Germany are OSS-reportable but are sometimes omitted by sellers who only report physical goods cross-border sales); and OSS quarterly returns whose total cross-border sales value differs materially from the cross-border sales volume implied by Amazon's DAC7 transaction count and average order value data. Each of these inconsistency types generates a query from the registration member state's tax authority that the seller must respond to with supporting documentation — and repeated inconsistencies across multiple quarters escalate from query to formal VAT audit. OSS return preparation and cross-border VAT rate accuracy applies the correct destination country VAT rate to each transaction in the OSS return — using the delivery address country and the applicable reduced or standard rate for the product category in that country — generating the rate-accurate OSS return that the automated cross-check validates without generating the rate-error flags that trigger manual review.
5. The Reverse Charge Mechanism for B2B Sales Requires Verified VAT Numbers
Cross-border B2B sales within the EU are zero-rated for VAT by the seller when the buyer provides a valid VAT number — the reverse charge mechanism that transfers the VAT accounting obligation from the seller to the buyer in the destination country. For Amazon sellers who sell both to consumers (B2C) and to businesses (B2B) across the EU, correctly applying the reverse charge requires obtaining and validating the buyer's VAT number at the point of sale, applying zero-rate VAT on the invoice, and reporting the zero-rated supply on the EC Sales List for the period in which the sale occurred.
The compliance risk in reverse charge application is the validation step: a seller who applies zero-rate VAT on the basis of a VAT number that is invalid, expired, or belongs to a different entity than the buyer has incorrectly zero-rated the supply and is liable for the VAT that should have been charged. German tax law (and EU VAT Directive Article 138) provides a good faith defence for sellers who validated the VAT number through the EU's VIES (VAT Information Exchange System) database at the time of the transaction and retained the validation record — but the good faith defence requires documented VIES validation at the transaction date, not retrospective validation when the audit arrives. B2B VAT number validation workflow for EU cross-border sales performs real-time VIES validation for every B2B transaction and retains the validation timestamp and result in the transaction record — creating the documented good faith defence that the reverse charge zero-rating requires and that a tax audit examines as the first evidence that the zero-rating was legitimately applied.
6. German VAT Compliance: Finanzamt Requirements, Umsatzsteuervoranmeldung Filing, and the 2026 Digitalisation Push
Germany remains the most important single VAT jurisdiction for most EU Amazon sellers — both because Amazon Germany is the largest EU marketplace by seller revenue and because German FBA inventory creates the local VAT registration and filing obligations that generate the highest compliance volume. The Finanzamt (German tax office) requires VAT-registered sellers to file Umsatzsteuervoranmeldung (advance VAT returns) monthly for the first two years of registration, reverting to quarterly filing after a compliance track record is established — a monthly filing frequency that requires the transaction data pipeline to produce accurate monthly input VAT and output VAT totals rather than the quarterly aggregates that OSS reporting uses.
Germany's push toward digital VAT reporting — the planned introduction of mandatory electronic invoicing (E-Rechnung) for B2B transactions from 2025 and the longer-term move toward real-time VAT reporting that the European Commission's ViDA (VAT in the Digital Age) initiative is driving — is creating new technical requirements for sellers' invoicing systems. E-Rechnung for German B2B transactions requires invoices in a structured XML format (XRechnung or ZUGFeRD) that can be processed by the buyer's accounting system and validated by the tax authority's digital infrastructure — a format requirement that sellers using PDF invoice generation through Amazon's VAT Calculation Service or third-party tools must verify their current invoicing outputs meet. German VAT filing and e-invoicing compliance for FBA sellers manages the Umsatzsteuervoranmeldung data preparation for German-registered FBA sellers — extracting the domestic sales, intra-community acquisitions, and input VAT data from the fulfillment and procurement transaction records that the monthly advance return requires, and verifying that the B2B invoice format meets the E-Rechnung structured format requirements that German tax compliance demands.
7. ViDA — VAT in the Digital Age — and What the 2025–2028 Implementation Schedule Means for EU Sellers Now
The European Commission's VAT in the Digital Age (ViDA) package — formally adopted by the EU Council in 2024 — introduces the most significant structural changes to EU VAT reporting since the OSS framework in 2021. ViDA's three pillars are: digital reporting requirements (real-time or near-real-time transaction reporting to tax authorities, replacing the periodic summary reporting of EC Sales Lists for intra-EU B2B transactions); the deemed supplier rule extension (making platforms like Amazon the VAT collector for all sales facilitated through their marketplace, not just for non-EU sellers); and the single EU VAT registration framework (extending OSS to cover more transaction types currently requiring local VAT registration, reducing the number of countries where separate registration is mandatory).
The ViDA implementation schedule runs from 2025 to 2028, with different pillars taking effect at different dates. The deemed supplier extension — most relevant for Amazon sellers — takes full effect from 2027, meaning Amazon will collect and remit VAT for all marketplace sales in the EU regardless of whether the seller is EU-established, removing the current distinction between EU and non-EU sellers for VAT collection purposes. The single VAT registration extension — which would reduce local VAT registration requirements for sellers whose only connection to a member state is through FBA inventory — is the most complex pillar with the longest implementation horizon, and sellers should not adjust their current local VAT registration structure in anticipation of single registration simplification that has not yet taken effect. Preparing EU VAT compliance infrastructure for ViDA implementation monitors the ViDA implementation timeline and translates each confirmed implementation date into the operational changes that FBA sellers' VAT compliance processes require — allowing sellers to adapt their reporting workflows as each ViDA pillar takes effect rather than discovering a compliance gap after the new requirement's effective date has passed.
Why 2026 EU VAT Enforcement Will Be Harder for Amazon Sellers to Outsmart
The seven VAT rules covered in this guide represent the compliance obligations that will generate the most enforcement activity against EU Amazon sellers in 2026: OSS threshold miscalculation, local VAT registration gaps exposed by DAC7, OSS-to-local-VAT cross-check mismatches, reverse charge validation failures, German advance return accuracy, and the forward-looking ViDA changes that sellers need to understand now even though their full implementation lies ahead. Each rule requires a specific compliance process — not a general awareness of EU VAT complexity — because the enforcement infrastructure that the EU has built since 2021 is now technically capable of identifying non-compliance at the transaction level rather than the annual audit level that previously limited enforcement to sellers with the most egregious VAT gaps.
