Could you attach a debug report to check what’s happening in this case?

Hello Tim,

Since Weight Based Shipping doesn’t control the tax calculation process (aside from the Taxable / Non Taxable switch), the issue is likely related to other parts of your installation.

Contacting the support team of the plugin you are using for automatic taxes can help you resolve the issue faster since they are more experienced with tax calculation issues.

@masteradhoc you can disable the shipping tax in the WooCommerce tax settings https://i.imgur.com/K73RkEc.png

When this option is enabled, regular items are quoted by their total weight disregarding their length, width, and height.

You can turn this off to quote each item individually, considering both its weight and dimensions.

Hi @gagilbert13,

Glad the plugin works for you. You can leave a quick review:

Local Pickup is a core WooCommerce feature. It’s unlikely to conflict with USPS Simple. Probably a caching issue.

Could you check if the issue persists if you deactivate USPS Simple temporarily?

Hello @mhefti,

Since Weight Based Shipping doesn’t control the tax calculation process (aside from the Taxable / Non Taxable switch), the issue is likely related to other parts of your installation.

Could you create a temporary Flat Rate shipping option to check if the issue persists for it as well?

Could you attach screenshots of your tax settings and pages showing the problem?

Are you using any plugin for tax management?

Hello @waxinggibbous,

Adding the following code snippet to your theme’s functions.php will increase the shipping costs by the predefined percentage:

add_filter('woocommerce_package_rates', function ($rates) {

    $percentage_increase = 0.10; // 10% increase. Change this to your desired percentage (e.g., 0.15 for 15%).

    foreach ($rates as $rate_id => $rate) {
        $original_cost = $rate->cost;
        $new_cost = $original_cost + ($original_cost * $percentage_increase);
        $rate->cost = $new_cost;

        // Increase the cost of shipping taxes as well if applicable
        if (!empty($rate->taxes)) {
            foreach ($rate->taxes as $tax_id => $tax) {
                $rate->taxes[$tax_id] = $tax + ($tax * $percentage_increase);
            }
        }
    }

    return $rates;
});

Hello @lauraslezinger,

Do you have the Quote regular items by weight option enabled?

Hello @kinga01,

The new rules are always taxable.

Are you looking for a way to turn the shipping tax off?

I can see the following options to disable the shipping tax in this case:
– Adjust the woocommerce tax plugin settings to prevent it putting the shipping check back, if that’s supported.
– Find a custom code snippet to forcedly disable the shipping tax.
– Switch to another plugin for USPS.

WooCommerce 9.7 changed the way it detects global shipping methods, affecting WBS. As a result, the WBS global shipping method will not be available to your customers if it’s the only shipping method set up. Adding a method to a shipping zone serves as a workaround.

WBS 6.5.0 includes a fix for that.

It’s recommended to wait until all your plugins report compatibility with the new WooCommerce version before updating.

It’s up to you whether to use shipping zones, the global method, or both.

It is safe to update the plugin to the latest version since both the legacy and new UIs are supported simultaneously.

The legacy version remains fully functional, with no current plans for shutting down.

Both new and legacy shipping methods can be active on the same site, which might facilitate a gradual migration to the new UI.

Converting the legacy rules is optional. If you choose to do so, you’ll need to manually re-create them in the new UI.

Glad you have solved it! Thank you for the update.

Thank you for the debug report.

The maximum weight for First-Class Mail envelopes is 13 oz, while the package in the report was 7 lbs.

The plugin is not tied to any shipping zone, so it doesn’t appear in the Add shipping method list.

To prevent a tax from applying to shipping, uncheck the Shipping checkbox: https://imgur.com/a/h3PQxuP

Hi @diffhu,

By default, WooCommerce includes the shipping details into the confirmation email. This is not controlled by Weight Based Shipping, but rather a core feature.

If that isn’t happening in your installation, it might be related to a plugin, custom code snippet, or your current theme. To check that, temporarily disable all other plugins and switch to the default theme, and see if it helps. If so, return things back one at a time until it stops working again. Now you know the culprit.
