# Tax Engine

The Tax Engine setting controls how <code class="expression">space.vars.productName</code> calculates tax for transactions in this subsidiary. It's a per-subsidiary choice; different entities in your NetSuite account can use different tax engines independently.

## Accessing Tax Engine

{% stepper %}
{% step %}

### Open the NetSuite Admin view

Switch to **NetSuite Admin** in <code class="expression">space.vars.productName</code>.
{% endstep %}

{% step %}

### Select the subsidiary

Use the subsidiary switcher at the top right.
{% endstep %}

{% step %}

### Open Configurations

Click **Configurations** in the left sidebar, then scroll to the **Tax Engine** section.
{% endstep %}
{% endstepper %}

## Tax Engine options

| Option              | Description                                                                                                                                   |
| ------------------- | --------------------------------------------------------------------------------------------------------------------------------------------- |
| **NetSuite Native** | Uses NetSuite's built-in tax groups, codes, and nexus configuration. The standard choice when your tax setup lives entirely in NetSuite.      |
| **Avalara**         | Delegates real-time tax calculation to Avalara's AvaTax service. Requires the Avalara integration to be installed and configured in NetSuite. |

## Choosing the right option

* **NetSuite Native** works for businesses with simple, predictable tax obligations whose tax tables are already configured in NetSuite. No additional integration is needed.
* **Avalara** is the right choice for businesses with multi-state nexus, frequent rate changes, or sales-tax compliance requirements that benefit from a dedicated tax engine. The Avalara integration must already be active in your NetSuite account.

## Saving changes

Use the **Save Changes** button at the top of the Configurations page. Changes apply to new transactions immediately; in-flight orders keep their original calculation.
