How do I add GST to a WooCommerce Product?

To add GST in WooCommerce, first enable taxes. Go to WooCommerce → Settings → General and tick “Enable taxes,” then save. Set your store address to India. Open the Tax tab and choose whether product prices include GST. In Standard rates (or a custom “GST” class), add rows for your GST slabs, like 5%, 12%, 18%, or 28%, with Country = IN and State/Postcode if required. Save. Now edit the product, open Product data → Tax, select the correct Tax class, and set Tax status to Taxable. Update the product and test checkout totals. Add HSN code in product notes.
