Yes, Zazzle collects the sales tax for all orders on your behalf as a Maker. We will only collect sales tax on orders from states that are specified in the Shipping and Sales Tax settings in your account. Also note, sales tax is based upon the shipping address of the order, not the billing address.
You can manage your sales tax settings by logging into your account and going to the Shipping and Sales Tax tab in your account settings. To select which state you wish to collect tax from, simply click on the box next to each of the relevant states and click save. There is also an option if you do not collect sales tax.
Once collected, Zazzle will forward the full sales tax amount to you during each bi-monthly pay period.
