When selling to businesses it is common to charge a 0% reverse tax on your products and services if your customers are located outside of the country you are originated. Those businesses are then required to handle their own VAT submission and payment in their own country.
B2B 0% reverse VAT taxation can be set up by using additional settings when creating a Tax Rate.
Create a B2B 0% reverse Tax Rate
In your Firmhouse project, go to to Taxes & Invoices in the sidebar.
Click Create new tax rate
Under Rate, enter the tax percentage and set the tax type to Exclusive.
Then select from the B2B origin country dropdown the country you are based in and/or want to treat as origin. The dropdown will only show countries you've enabled for your project under Settings > Subscription model in your Firmhouse project.
Now set this tax rate as the default for your project and make sure all your appropriate plans and products are also set to use this tax rate. See the article about managing tax rates to learn how to do this.
Sample Checkout with B2B 0% reverse tax in action
In the following image you will see that:
The checkout on the left has taxes applied when the customer's country is set to Netherlands. This is the country set as B2B origin country in the Tax Rate.
The checkout on the right shows no taxes applied to a customer signing up in Belgium.
