CarVertical, Lithuanian firm, sells used car reports in Poland. Customers using Polish addresses and BLIK payments can select 0% VAT from Bahamas or Afghanistan. System defaults to 23% Polish VAT but allows easy change to lower rates. This drops report price from 108 zł to 88 zł. Experts call it illegal under EU rules requiring seller verification of buyer location. Polish tax authorities should get VAT based on buyer residence via IP or address. Practice risks lower Polish budget revenues from 350k+ annual Polish purchases. Company claims IP and language auto-assign VAT correctly. Users can override via VPN or language choice without penalty. Experts say responsibility lies with seller, not buyers. Firm passed audits in Poland and elsewhere.
