Bulgaria for Amazon FBA Sellers: Pan-EU VAT, IOSS & EOOD Guide (2026)

An Amazon FBA seller moving to Bulgaria cuts corporate tax from 20-30% to 10%, replaces marginal dividend rates of 26-32% with a 5% Bulgarian dividend tax, and keeps full access to Pan-EU FBA. The trade-off is a multi-country VAT footprint that does not simplify just because the seller is now Bulgarian — the goods are in the warehouse countries, and the warehouse countries still want their VAT. This guide covers the operational playbook: the new 2026 Pan-EU 5-VAT requirement, IOSS vs OSS, Amazon's deemed-supplier role, Multi-Country Inventory as a footprint-reducing tool, and the Bulgarian EOOD setup that makes it all work.

Why FBA Sellers Look at Bulgaria

Three reasons:

• Headline rate: 10% CIT + 5% dividend = 15% combined on distributed EOOD profit, vs 28-32% combined in most EU countries.
• Lean operating costs: accountant, bookkeeper, office, and (if needed) warehouse staff are materially cheaper in Sofia or Plovdiv than in Berlin, Amsterdam, Warsaw, or Dublin.
• EU + Schengen access: Bulgaria in the EU, the Schengen area (since Jan 2025), and the eurozone (since Jan 2026). No currency conversion on EU settlements.

What Bulgaria does not do: eliminate the need to be VAT-registered in every country where FBA stores your inventory. That obligation is fixed by EU VAT law, not by the seller's country of residence.

The FBA VAT Footprint Problem

Under EU VAT law, storing inventory in a country creates a VAT registration obligation in that country, because the goods are physically in the jurisdiction at the moment of supply. Amazon's FBA programmes distribute inventory in the following ways:

As of 2026, Amazon requires Pan-EU FBA sellers to hold active VAT registrations in a minimum of five EU countries to remain eligible for Pan-EU (previously four). Sellers who do not meet the threshold lose the Pan-EU rotation benefits and revert to MCI or EFN with constrained local stock.

OSS, IOSS, and When Each Applies

OSS (One Stop Shop)

Applies to cross-border B2C sales inside the EU above the EUR 10,000 pan-EU threshold. For an EU-established FBA seller:

• Cross-border B2C sales (goods moved from a warehouse in one Member State to a consumer in another) are reported through a single quarterly OSS return filed with the Bulgarian NRA.
• Local VAT (consumer's Member State rate) is charged and collected through OSS.
• Intra-Community transfers of own goods (warehouse to warehouse) are reported as zero-rated dispatches and acquisitions under the local VAT registrations in each country.

IOSS (Import One Stop Shop)

Applies to low-value consignments (up to EUR 150) imported from outside the EU for direct sale to EU consumers. When Amazon acts as the deemed supplier (typical for imports into the EU through FBA), Amazon handles IOSS — the seller does not separately register. For direct sales through a Shopify or other non-Amazon channel that imports low-value goods from outside the EU, IOSS registration is generally mandatory above 25 parcels per month.

Amazon as the Deemed Supplier

Under the 2021 EU e-commerce VAT package, Amazon is treated as the deemed supplier for VAT purposes in two scenarios:

1. Distance sales of imported goods with consignment value up to EUR 150, sold to EU consumers through the Amazon marketplace.
2. B2C supplies within the EU where the underlying seller is established outside the EU and the goods are sold to EU consumers through Amazon.

For a Bulgarian-established EOOD selling to EU consumers with inventory already inside the EU, Amazon is generally not the deemed supplier — the EOOD is the supplier, charges local VAT at the consumer's rate, and remits through OSS or local filings. The practical difference: a Bulgarian-established seller keeps the full invoice flow and VAT responsibility (with corresponding input VAT recovery on expenses); a non-EU seller shifts that to Amazon but loses some input VAT recovery.

The Bulgarian EOOD Setup for an FBA Seller

Why EOOD, not freelancer

FBA is an inventory and logistics business. It typically involves:

• Physical goods and working capital tied up in stock.
• Multiple platform fees (referral, FBA, advertising, storage, long-term storage).
• Warehouse contracts, shipping agreements, return processing.
• Often employees or contractors (PPC manager, listing specialist, customer service).
• Cross-border VAT registrations in several countries.

All of this fits naturally into an EOOD structure. Freelancer status is inappropriate for a genuine product business — the expense deduction under Art. 29 ЗДДФЛ is designed for service providers, not for sellers of goods with a real cost of goods sold and inventory.

What the Bulgarian side includes

• EOOD formation — articles, capital account, Commercial Registry filing, NRA and NHIF registrations.
• Bulgarian VAT registration — the domestic VAT number that ties into VIES, reverse-charge invoicing, and input VAT recovery on local expenses.
• OSS registration through the Bulgarian NRA.
• Customs EORI number — mandatory for any imports / exports outside the EU.
• Bank account (DSK, UniCredit, UBB, Postbank typical choices) + Wise / Revolut Business for FX on multi-currency marketplaces.
• Amazon Seller Central entity switch — change the legal entity and refresh bank details, tax documents, and VAT profiles.

What sits outside the Bulgarian scope

• Foreign VAT registrations in DE, FR, IT, ES, PL (or wherever your FBA footprint is) — handled by local VAT agents or specialist providers (Avalara, hellotax, SimplyVAT, Amavat, Taxdoo, etc.).
• Customs clearance on non-EU imports — customs broker in the port of entry.
• Product compliance (CE marking, WEEE, packaging, EPR) — specialist product-compliance providers.

Timeline for FBA Relocation

1. Week 0 — Diagnostic. Revenue, marketplaces, FBA programme (EFN / MCI / Pan-EU), current legal entity, foreign VAT registrations, team, inventory locations.
2. Week 1-2 — EOOD and Bulgarian registrations. Formation, BULSTAT / Commercial Registry, NRA, VAT, OSS, EORI, bank.
3. Week 2-4 — Foreign VAT handover. Re-register foreign VAT numbers under the new Bulgarian entity (or establish new ones where needed). Confirm Pan-EU 5-country compliance.
4. Week 3-5 — Seller Central entity switch. Upload new articles of association, new tax forms, new bank details. Amazon verifies in 2-6 weeks.
5. Week 4-6 — Bulgarian residence. EU residence or D-visa, long-term home in Sofia or Plovdiv, NHIF, GP registration.
6. Month 2+ — Operations. Monthly VAT in Bulgaria + each warehouse country. Quarterly OSS. Annual corporate return.

Common Mistakes

1. Assuming Bulgaria eliminates foreign VAT registrations

It does not. Inventory in a German warehouse creates a German VAT registration regardless of where the seller is resident.

2. Missing the 2026 Pan-EU 5-country threshold

Sellers with only 4 active registrations lose Pan-EU. Confirm active status in all 5+ before the first FBA rotation of 2026.

3. Using freelancer status for a product business

The 25% Art. 29(1)(3) ЗДДФЛ deduction is for service providers. Product sellers need an EOOD.

4. Mixing personal bank and Amazon disbursements

Amazon disbursements must go to the EOOD bank account, not a personal account. Open the business account before the Seller Central switch.

5. Not planning for product-compliance costs

EPR (Extended Producer Responsibility) in France, Germany, Spain, etc. is a separate registration and fee burden — outside VAT but mandatory for Amazon compliance.
