Common Mistakes

❌ Waiting until revenue far exceeds the threshold to register

💥 Consequence: Backdated VAT liability from the date you should have registered, plus penalties

✅ Fix: Register as soon as you expect to exceed £90,000 taxable turnover (12-month rolling)

❌ Assuming platform (Amazon/TikTok) handles VAT registration for you

💥 Consequence: Platform collects VAT only in some markets; you remain liable for registration in countries where you store stock

✅ Fix: Check which countries require YOUR registration regardless of platform

❌ Not having a local fiscal representative when required

💥 Consequence: Registration rejected or delayed; non-EU sellers in Italy/Spain/Greece often need one

✅ Fix: Check if UK requires a fiscal representative for non-EU entities

Seller Paths

Non-EU seller, no EU warehouse, B2C under €150

1. IOSS registration through intermediary — no local registration needed

Non-EU seller with FBA warehouse in EU country

1. Must register VAT in the warehouse country + OSS for other EU sales. English; generally accessible for non-native speakers

EU-based seller, single country warehouse

1. Register locally + OSS for cross-border B2C. May need local registration in customer countries for B2B.

B2B only (no B2C)

1. Register in each country where you make B2B supplies; reverse charge applies but you still need a VAT number
