To follow the EU relegations regarding taxes, some people within EU are required to pay VAT depending on their country. This is fairly easily as PayPal allows you to set a VAT amount for each country individually. However Xenforo seems to be having issues with this. Whenever someone buys and upgrade with VAT paid, Xenforo notices it's not the expected amount and rejects the upgrade.
Example, user from UK buys $10 account upgrade. They check out, paypal adds 20% tax. The amount is $12 now. XenForo expects $10 and won't process the upgrade for this reason.
Any way of quickly fixing this?
