Gelato is legally obligated to pay VAT and sales taxes on some customers' orders. Whether or not tax is due depends on the item purchased, the shipping destination, the buyer's location, the production (printing) location, and the actual tax rate determined by the applicable state/country and/or local tax rates. You can find this information on the order detail page by clicking on the info callout next to "Tax" - see below:
Gelato is not a financial or tax advisor, for specific questions related to VAT we recommend you reach out to your accountant.
