For this guide you will need to have a VAT Sense API Key, you can get a free one at vatsense.com.

VAT Sense is an API that allows you to fetch tax rates, calculate tax prices, and validate tax numbers. Today we'll look at the tax price calculation functionality.

Here we'll show you how to derive the tax price for Denmark via the VAT Sense API. This will return the tax rate for Denmark as well as the total amount of the price if the price is exclusive of tax and how much of the price is tax if it's inclusive of tax all depending on the tax rate for Denmark.

Tax Rates

Tax rates change in each country so if you want to calculate the amount of tax you need to collect you need to know which country and which kind of item you're calculating tax for.

For digital products such as eBooks, SaaS, etc. then you need to charge the tax rate of the country the customer resides in.

For example, if you are selling an ebook it may be a different rate than if you're selling a subscription to a SaaS. And if you sell an ebook to someone residing in Denmark it'll probably be a different rate than if you sold it to someone in a different country.

This means you will want to calculate the tax price every time you sell to a customer instead of calculating it once and reusing that calculation.

VAT Sense can manage this for you by providing you with an endpoint where you provide them the info to calculate the tax and it provides you all the information.
