How do I Add or Enable Tax in WooCommerce?

Go to WooCommerce → Settings → General, confirm your store address and currency. Scroll to “Enable taxes” and tick it, then Save changes. A new Tax tab appears. Open WooCommerce → Settings → Tax and choose whether prices include tax, how to display tax in cart/checkout, and whether shipping is taxable. Next, add tax rates: pick Standard (or create additional tax classes), click “Insert row,” then enter country/state, postcode, city, rate %, tax name, and priority. Save. Finally, place a test order to verify the correct tax shows for each location. If you sell globally, create separate rows per region.
