Description

TaxAutomator – Tax Rate Lookup for Woo Commerce is a lightweight connector that calls the TaxAutomator API during Woo Commerce tax-rate matching. It is intended for merchants that want a simple way to use TaxAutomator rate data inside Woo Commerce checkout flows.

This plugin connects Woo Commerce to the TaxAutomator service at taxautomator.net. A TaxAutomator account or API key may be required for production usage depending on the merchant’s plan and deployment settings.

During checkout tax matching or Test Connection, the plugin sends the destination ZIP or postal code to TaxAutomator. Example lookup:

GET https://taxautomator.net/api/v1/rates?zip=90210

Canadian postal codes are URL-encoded when needed, for example:

GET https://taxautomator.net/api/v1/rates?zip=M5V%202T6

When an API key is configured, the plugin sends it with the request for authorization. A successful response includes the total rate, state or province code, rate components, effective period, and API version. Woo Commerce receives the total rate as a percentage tax rate.

Diagnostics

The settings page includes a Test Connection tool. It calls the same TaxAutomator API endpoint used during checkout, but it only displays a minimal connectivity result: success message, redacted postal code, API version, and timestamp. It does not display rate values, rate components, jurisdictions, or effective periods. Failed API calls are written to the Woo Commerce logger with source taxautomator; API keys are not included in diagnostic output or log context.

Privacy

When enabled, the plugin sends the destination ZIP or postal code to the fixed TaxAutomator service endpoint at https://taxautomator.net to retrieve a rate quote. Optional API keys are stored in WordPress options, are not printed on the settings page after saving, and are not written to diagnostics or WooCommerce logs.

The plugin does not add storefront tracking pixels, does not embed public credit links, and does not load remote JavaScript or CSS. It only contacts the configured TaxAutomator API endpoint when tax matching or the Test Connection tool needs a rate quote.

External service

This plugin depends on the TaxAutomator API service for rate lookup. The API receives the postal code being quoted and returns a rate response for Woo Commerce tax matching. The service endpoint is fixed to https://taxautomator.net and is not editable in WordPress.

Installation

Install from WordPress.org, upload the plugin ZIP through WordPress Admin, or copy the extracted plugin folder into wp-content/plugins/.
Activate TaxAutomator – Tax Rate Lookup for Woo Commerce.
Open Settings > TaxAutomator – Tax Rate Lookup for Woo Commerce.
Keep Woo Commerce taxes enabled.
Use Settings > TaxAutomator – Tax Rate Lookup for Woo Commerce > Test Connection with a sample ZIP or Canadian postal code.
Enable TaxAutomator tax matching only after the connection test succeeds and your Woo Commerce tax settings are ready.

If your TaxAutomator API key is restricted by domain, add your WordPress site domain to the key’s allowed domains in the TaxAutomator Dashboard. Exact domains and wildcard subdomains such as *.example.com are supported.

FAQ

Does this replace tax advice?: No. TaxAutomator provides rate data. Merchants remain responsible for their tax obligations and Woo Commerce configuration.
Does the current TaxAutomator API require an API key?: Yes. Test Connection and checkout tax matching require a TaxAutomator API key.
Does activation immediately change checkout tax rates?: No. The plugin includes an Enable tax matching setting. Leave it disabled until Test Connection succeeds and your Woo Commerce tax settings are ready.
Which platform is first-class?: Woo Commerce is the first self-serve, first-class extension because it has a large install base and direct plugin hooks for tax matching.
