I have a complex notice written entirely in Spanish that I can't understand, but which with the help of Google translate I have decoded to indicate that some 100 odd euros is being withheld from me as the customer paid for my services and has voluntarily paid some kind of tax on my behalf. I am sure with sufficient effort I can probably find a way to get that 100 euros refunded, but boy, it sure aint worth my time. But I mention it because while you may have no obligation to do anything, you can find oneself in this "withholding" situation if you don't.

How do you distinguish between that and some form of scam/fraud?

I suppose that's a good point - it would be a remarkably well executed scam, since it had all the account numbers, and details that I use with that client, as well as the actual amount from the invoice I sent them, printed on it. I didn't hesitate to believe it at the time.
