Collect taxes in Checkout

When calculating tax, Stripe Tax uses information stored on the Products and Prices APIs to determine the right rates and rules. You can update your Checkout products and prices to include:

• tax_behavior—Specifies whether the price is considered inclusive or exclusive of taxes.
• tax_code (optional)—Specifies the product tax code. If you don’t set a tax_code on a product, we apply your preset product tax code. For more information, consult our list of tax codes.

When you set the tax_behavior parameter to exclusive, it adds tax to the subtotal. This is common in US markets and for business-to-business (B2B) sales. If you set the tax_behavior to inclusive, the amount your buyer pays never changes (even if the tax rate varies). This is common practice for business-to-consumer (B2C) buyers in markets outside of the US. If you don’t want to create your products and prices upfront, you can pass the price_data.tax_behavior and product_data.tax_code parameters in your Checkout session.

After updating your products and prices, you’re ready to start calculating tax on your Checkout sessions. You can create sessions for one-time and recurring purchases.

To calculate tax for new customers, Checkout validates and uses the provided shipping or billing address. For existing customers, Checkout calculates tax by validating and using the attached customer shipping or billing address. If you capture a new billing or shipping address for an existing customer, Checkout won’t automatically override the previous billing or shipping information. You must explicitly request customer address changes.

Apple Pay and Google Pay

If you wish to ensure that Google Pay is offered as a payment method while using Stripe Tax in Checkout, you must require collecting a shipping address. Apple Pay with Stripe Tax displays only when the customer’s browser supports Apple Pay version 12.

If you don’t pass in an existing customer when creating a Checkout session, Checkout creates a new customer and automatically saves the billing address and shipping information. Checkout uses the shipping address entered during the session to determine the customer’s location for calculating tax. If you don’t collect shipping information, Checkout uses the billing address.
