We are dealing with a strange situation for the past few days.
Some payments we receive through paypal are not charged with VAT at all.
Example:
UserA located in Greece pays through Paypal and is charged correctly with the net amount + VAT = total (18eur + 4.32eur = 22.32eur).
UserB located in Greece, pays through Paypal and he is not charged VAT at all! (18eur + 0eur =18.00eur total).
The above clients (UserA and UserB) are from the same country, paid for the same subscription and paid with a time difference of a few minutes.
This does not happen all the time. We had about 80 sales the last 3 days and this happened 5 times. All 5 times we had to refund the payment in order to be in compliance with the OSS EU directive.
In one of the 3 cases that we refunded, the same user, paid again without any problems. This time the VAT was charged normally!
Tax rules configuration is correct, everything was working great since 01/01/2026 that we started charging VAT and nothing has changed.
Example of Notification's raw data (Same Country, Same subscription, one is charged with VAT but the other is not)
Here are the invoices for the above
Can you please advise?
