WooCommerce: Get Order Tax Percentage

You’d think WooCommerce had an easy way to get the order tax rate percentage, the same way as you can get almost everything inside the “order object” with a single line of PHP. Well, that’s not the case unfortunately.

The reason is that probably each order can have multiple tax rates, and that tax is not only applied to product prices, but also optionally to shipping, fees and more.

So, how do we get the list of tax rates in a WooCommerce order? Here’s a quick snippet that you can use – enjoy!

PHP Snippet: Get List of WooCommerce Order Tax Percentages

The function below “returns” an array of percentages – you can then use that in a plugin, snippet or theme in order to do calculations or print it somewhere.

function bbloomer_woocommerce_get_tax_rates( $order ) {
	$rates = array();
	foreach ( $order->get_items('tax') as $item_id => $item ) {
		$tax_rate_id = $item->get_rate_id();
		$rates[] = WC_Tax::get_rate_percent( $tax_rate_id );
	}
	return $rates;
}

Where to add custom code?

You should place custom PHP in functions.php and custom CSS in style.css of your child theme: where to place WooCommerce customization?

This code still works, unless you report otherwise. To exclude conflicts, temporarily switch to the Storefront theme, disable all plugins except WooCommerce, and test the snippet again: WooCommerce troubleshooting 101
