What this means for your store
- You can enable HPOS with WooCommerce Tax active: the plugin's own code declares it supports the HPOS order tables. As with any change to order storage, try it on a staging copy first.
- If your store uses the block-based Cart and Checkout (the default for new WooCommerce stores), check that WooCommerce Tax's features appear there on a staging copy. The classic checkout (the [woocommerce_checkout] shortcode) is the fallback.
- Its code does use the WooCommerce Blocks integration API (payment gateways typically register a block payment method this way), so it likely works in the block checkout even without a declaration. This is a hint from the code, not a declaration.
