Tax Form W-8 info supplied but still US tax is taken

#1

Hello,
I supplied Tax Form W-8 twice allready but still US tax is taken from my US sales.
What could be wrong with this?
Thank you.

Unfortunately, Croatia does not have a double tax treaty with the USA.
You must pay 30% withholding tax only on US sales.
Without W-8 form it is 28% on all your sales.
