@creationmachinesllc We’re here to help you out if you run into any issues at all related to our plugin before, during, or after your TaxJar trial. No monthly subscription is required for prompt, friendly support.

When our plugin is installed, we always back up your existing tax rates to /wp-content/uploads . You’ll find a CSV file starting with taxjar-wc_tax_rates. We also clear your cache (e.g. transients) and set some default WooCommerce tax settings to ensure our plugin will work properly.

If you decide to uninstall the plugin, you can use the backup CSV file to re-populate your tax rates under WooCommerce > Settings > Tax. Select your primary tax class and click the “Import CSV” button to upload the CSV file manually or provide the file path on your server. After uninstalling, you’ll be able to use WooCommerce’s native tax calculations without any issues.

We absolutely do not override or inject code outside of our plugin directory, so once our plugin is deleted it’s completely gone. Our plugin is open source on GitHub if you’d like to review the code in more detail.

@clickstudio The latest version of TaxJar’s plugin (v1.3) now supports WooCommerce Subscriptions. If there’s other third party plugins you’d like supported, please let me know. We’ll also help fix any issues you experience right away if you reach out to our support team. Thank you!

Update: One hook you can use is woocommerce_before_save_order_items via wc_save_order_items called here: https://github.com/woocommerce/woocommerce/blob/21baa5d2304bd1806592480feb10a1748e0dd77f/includes/class-wc-ajax.php#L1024

I was able to get all the data I need with $order_id and the address info available in $_POST when the “Recalculate” button is clicked.

Bumping this thread. Can you provide the other hooks to assist with calculating tax for backend orders?

Both woocommerce_ajax_calc_line_taxes and woocommerce_ajax_after_calc_line_taxes were removed in this commit: https://github.com/woocommerce/woocommerce/commit/c88984eb0e7cf4e24fde92a7ea1ea9e9b3d8750c

The closest hook I could find is woocommerce_calc_tax when calculating tax for individual lines, but this isn’t ideal. For building plugins that communicate with a sales tax API, we need something like woocommerce_calculate_totals for backend orders.

Thank you!
