Aeion Tax for EU VAT Cross-Border
Selling into the EU means navigating 27 countries × different VAT rates, the post-Brexit One Stop Shop (OSS) regime, Import One Stop Shop (IOSS) for goods, and B2B reverse charge rules that require a valid EU VAT ID. Aeion Tax computes VAT locally — zero per-calculation fees, VAT-inclusive pricing for EU consumers, reverse charge for customers with a VAT ID on file, per-country digital-service-tax rules, and the per-country sales/VAT breakdown you need to prepare your quarterly OSS return.

How OSS Works With Aeion
`
B2B Reverse Charge
Being honest upfront: Aeion Tax does not integrate with the EU's VIES (VAT Information Exchange System) for real-time VAT ID validation. Reverse charge in Aeion is handled through the same tax-exemption mechanism used for resellers, nonprofits, and government buyers elsewhere in the platform — a manually-entered, admin-verified exemption record, not an automated VIES lookup at checkout.

What Aeion Tax Does NOT Cover for EU
Being honest:
FAQ
No — that was the old regime. OSS (since July 2021) means ONE registration in your country of identification covers all EU cross-border B2C sales. Aeion computes the correct per-country VAT on each sale and gives you the per-country breakdown for that one OSS return; you still register and file it yourself.
Country of identification doesn't affect VAT rate — rates are based on customer's country, not yours. Choose country of identification for filing convenience (language, e-filing portal quality).
UK left EU VAT system. EU sales to UK now treated as exports (no VAT charged); UK sales to EU treated as imports. UK has own MTD VAT system. Aeion handles both.
Historical EU rules apply. Aeion preserves audit trail.
Generally same: VAT at customer's location (B2C) or reverse charge (B2B). Some countries have specific SaaS classification rules; Aeion handles per-country.
Same digital service rules apply if it's "supply of services electronically". Crypto-to-crypto: often outside VAT scope. NFTs: usually VAT-able as digital services. Per-country interpretation varies.
Marketplace collects + remits VAT on your behalf in EU since 2021. Track separately (don't double-count). Aeion segregates marketplace vs direct sales.
No. Reverse charge requires a valid VAT ID, entered and verified as a tax exemption on the buyer's record. Without a verified exemption on file: standard VAT applies. Aeion enforces this at the exemption-lookup step.
Transitional rules ended 2024. Standard non-EU rules apply to UK now.
VAT is per customer's country regardless of currency. Customer in France paying in USD: still French VAT rate. Currency conversion at point of sale for VAT calculation; Aeion handles.
Per-transaction: timestamp, customer country (as passed at checkout), rate applied, product-class details, and currency conversion used — retained per your own audit-log retention policy. Aeion does not independently capture the "2 pieces of location evidence" EU digital-service rules call for, or VIES validation results (see the reverse-charge section above) — those need to come from your checkout flow if required for your audit defense.
