What you’re seeing: VAT is still charged even though the VAT number is valid.
Quick check (2 minutes)
- Is the VAT number validated as valid?
- Is the billing country different from your store country?
- Are both countries EU members?
Confirm the validation result in Logs
- Go to EU VAT Checker → Logs
- Search for the order or VAT number
- Confirm the result shows Valid and the correct country
If all conditions are met but VAT is still charged, check WooCommerce tax settings and other tax plugins.
