# Manual tax calculators

Configure the manual tax calculator by creating one or more associated [tax rules](https://docs.commercelayer.io/core-api-reference/tax_rules). The rules will apply the related tax rate to the matching orders.

{% hint style="info" %}
Manual tax calculators support **location-based** tax rules only. For any other use case please consider creating an [external tax calculator](https://docs.commercelayer.io/core-api-reference/external_tax_calculators) that handles your own custom tax calculation logic or leveraging our out-of-the-box integrations with [Avalara](https://docs.commercelayer.io/core-api-reference/avalara_accounts) and [TaxJar](https://docs.commercelayer.io/core-api-reference/taxjar_accounts).
