# Charge tax

Stockeo allows you to decide whether to charge tax on a product based on data from the product feed.&#x20;

In the Data Mapping section, open the Add field dropdown, and select "Charge tax". Then specify the field in your product feed that determines whether a product is taxable.

The "Charge tax" field accepts the below values.

Positive values:

* yes, Yes, YES
* true, True, TRUE
* 1

Negative values:

* no, No, NO
* false, False, FALSE
* 0

You can use a Liquid expression to convert unsupported values, or to specify a fixed value.

For example, when your feed contains a VAT\_Taxable field with one of the two values _Y_, and _N_:

```
{%- case VAT_Taxable -%}
{%- when "Y" -%} yes
{%- when "N" -%} no
{%- else -%} yes
{%- endcase -%}
```

To specify a fixed value:

```
{{ "yes" }}
```
