Stripe Tax

Stripe Tax empowers your businesses to generate revenue around the globe without being impacted by complex tax compliance laws. It dynamically calculates tax based on customer locations and clearly displays it for your customers so they always know what they are paying.

Behind the scenes, it monitors transactions, pre-fills required tax registrations, and helps you submit new ones when necessary.

Back to top

Applying product-specific tax codes ensures you are charging customers the correct rate. Use Stripe's product tax codes to look up the codes for your product categories.

  1. Go to your product collection.
  2. Click on your product and add a code into the Stripe tax code field.
    • If you don't add a tax code here, your account will use the default tax code saved in your Stripe account.
    • Add txcd_00000000 if your product is not taxable.
  3. Click Save.


Fields required to calculate taxes

Back to top

Whether selling products on an order form or logging a manual transaction, you must send your customers’ location information to Stripe to calculate the taxes. Use the chart below to determine which location fields you must include on your form.

Add your products to order forms

Back to top

You must collect your customers’ location information on your order forms to calculate taxes. Set the location fields to “required” to ensure that you collect the required information.

  1. Add your taxable product to your order form.
  2. Add billing and/or shipping address fields to your order form.
  3. Click on the fields that are required to calculate the taxes.
  4. Check the “Required field?” checkbox.
  5. (Optional) Prefill the address fields to make filling out your form easier for your customers.
  6. Click Done.
  7. Save and publish your page.


Calculate tax on manual transactions

Back to top

Stripe can calculate the taxes on the manual transactions you create, but you must provide the same location information as you do on forms. The difference for manual transactions is that the required location fields are in your customers' credit card information instead of on your form.



Offline transactions

Back to top

Since offline transactions don’t have credit card information to pull from, when you log one, Ontraport will ask you to fill in location fields. This allows Stripe to calculate the taxes.

TaxJar

Back to top

Managing taxes based on a customer’s location can be difficult due to the varying tax rates across cities, states, regions and countries. This variability can be overwhelming and may restrict you to only selling products to customers in specific locations. By integrating TaxJar’s services, you can accurately collect taxes and open up new opportunities for sales.

Enable and configure your TaxJar integration

  1. Go to AdministrationBusiness InfoBusiness Information.
    • Enter your business address, business city, business zip/postal code, business state and business country.

  2. Go to your accountAdministrationIntegrationsTaxJar.
  3. Add your TaxJar live token to the “Live token” field.

  1. (Optional) Update your default tax code.
    • TaxJar will use this code if your products don’t contain a tax code. We recommend keeping the default tax code unless you have a good reason to change it. (For example, if you only sell one product type, such as live training services.) Use TaxJar’s tax categories page to locate applicable codes.
  2. Click Save.

Pro tip

Shipping address fields have precedent over billing address information. If you provide shipping and billing addresses on your forms or manual transactions, TaxJar will calculate the taxes based on your customers’ shipping address.
