I don't know every jurisdiction, but that's not the only relevant factor. If they are tax-deductible, they still introduce the need for paperwork etc. for the payment processor to let the payer deduct it from their own income. A 0% tax on some action doesn't imply you don't have to worry about tax law when performing said action.
Though I think you can just read the policy and take it at face value and not even have to know any of this beforehand.
