WooCommerce is a popular e-commerce platform that allows you to set up an online store and sell your products. One important aspect of running an online store is correctly calculating and collecting taxes on the products you sell. In WooCommerce, you can set the standard tax rates for your store, and by default, these tax rates are rounded to two decimal places. However, in some cases, you may need to round the tax rates to a different number of decimal places. In this article, we will show you how to set the standard tax rates to round to a specific number of decimal places in WooCommerce tax settings.

Here's how to do it:

1. Access the functions.php file of your WordPress site: You can do this through your WordPress dashboard by going to Appearance > Theme Editor.

2. Add the following code to the functions.php file:

add_filter( 'woocommerce_tax_rounding_mode', 'custom_tax_rounding_mode' );

function custom_tax_rounding_mode( $rounding_mode ) {
  return 'PHP_ROUND_HALF_UP';
}

add_filter( 'woocommerce_tax_rounding_precision', 'custom_tax_rounding_precision' );

function custom_tax_rounding_precision( $precision ) {
  return 1;
}

Note: In the code above, the PHP_ROUND_HALF_UP constant sets the rounding mode to round up, and the 1 value sets the precision to one decimal place.

3. Save the changes to the functions.php file.

With these steps, you have set the tax rounding mode to round up and the precision to one decimal place. This means that WooCommerce will round tax rates to one decimal place in the future. You can change the precision to any number of decimal places you need by adjusting the 1 value in the code.

Please keep in mind that making changes to your WordPress site's code can potentially cause issues, so it's important to make a backup of your site before making any changes. Additionally, you may need to consult a developer if you are not familiar with customizing WordPress site code.

In conclusion, rounding tax rates to a specific number of decimal places in WooCommerce tax settings is a simple process that can be done using a code snippet. By following the steps outlined in this article, you can configure your WooCommerce tax settings to meet your specific needs.
