VAT: rates and price display

How the shop calculates VAT, where the rates are and how prices including tax are displayed.

⏱ 5 minAdvancedUpdated 8 Oct 2026

When we set up the shop, we configure it so that you enter prices including VAT and customers see them including VAT. This article shows where the settings are in case something changes, for example the VAT rate.

A wrong tax setting changes prices across the whole shop. Write to us before you make a change.

VAT rates

Stores › Taxes › Tax Zones and Rates

Stores menu with the Tax Zones and Rates item highlighted
The Taxes group has the rates (Tax Zones and Rates) and the rules (Tax Rules).
  1. Open the rate (for example the Slovenian standard rate of 22 %) and enter the new value in Rate Percent. Save.

  2. For the reduced rate (9.5 % in Slovenia), add a rate with Add New Tax Rate and, in Tax Rules, link it to the tax class of the products it applies to.

If you sell to other EU countries through the One-Stop Shop (OSS) scheme, each country has its own rate. We set these up together.

Calculation and display

Stores › Configuration › Sales › Tax

  1. In the Calculation Settings group, these two settings matter most:

    Tax calculation settings
    1. Catalog Prices - Including Tax: you enter product prices including VAT.
    2. Shipping Prices - Including Tax: shipping costs are entered including VAT.
  2. In the Price Display Settings group, you choose how customers see prices:

    Price display settings
    1. Display Product Prices In Catalog
    2. Display Shipping Prices

On a product, VAT is set by the Tax Class field. For a product with the reduced rate, choose the matching class.

Common problems

The price in the cart is different from the price on the product

The display settings for the catalogue and the cart are different (including and excluding tax). In the Shopping Cart Display Settings group, choose the same as for the catalogue.

The order has no VAT

The product has the Tax Class "None", or there is no tax rate for the customer's country. Write to us with the order number.
