If you set up a tax in Arketa to be applied to a sale (such as a pack, subscription, retail item, or membership), the tax is calculated only on the price of the item and any applicable Stripe processing fees. Arketa's own transaction fees are not taxed.
Stripe does charge fees on taxes. This means that when a customer makes a payment and taxes are applied, Stripe’s processing fee is calculated on the total amount, including the tax portion.
For example:
If a customer pays $100 + $10 tax = $110 total
Stripe will charge their fee on the full $110 amount.
