# Sales Tax
Soulver can help you calculate sales tax, such as determining how much sales tax was paid on a gross price and what the pre-tax price was before tax was added.
### Setup
Open Soulver's **Money** settings and ensure that the correct name for sales tax (VAT, GST, etc) is set, with the correct percentage for your country or state:
Setting up sales tax in Soulver's regional settings
{% hint style="info" %}
Soulver sets sales tax defaults for many countries, including Australia, NZ, the UK and EU countries based on your device's regional settings.
Our American users must set their sales tax settings manually, as sales tax varies state-by-state in the US (and we don't want to ask for your geolocation).
{% endhint %}
### Working with sales tax
{% hint style="info" %}
The examples below assume a sales tax (VAT) of 15%.
{% endhint %}
#### Adding sales tax to an amount
```
$300 + VAT | $345.00
VAT on $300 | $45.00
```
#### Removing sales tax from a total
```
$300 - VAT | $260.87
VAT off $300 | $260.87
```
{% hint style="info" %}
Note that "$300 - VAT" is not the same as simply subtracting 15% from $300. Soulver correctly calculates the pre-tax price by dividing by 1.15, giving $260.87 (not $255).
{% endhint %}
#### Extracting the tax amount from a total
```
VAT in $300 | $39.13
VAT of $300 | $39.13
VAT from $300 | $39.13
```
