CartTaxify for WooCommerce

CartTaxify for WooCommerce lets store owners define simple, powerful tax rules based on cart value:

• Cart subtotal below the configured threshold → tax rate is applied automatically.
• Cart subtotal at or above the threshold → no tax (tax free).
• Each rule is tied to a specific currency, enabling true multi-currency tax logic.
• Works with any currency setup — no extra plugins required.

Key Features

• Add unlimited rules — one per currency
• Set your own threshold amount and tax rate per currency
• Optionally customize the tax label (e.g. “GST”, “VAT”)
• Clean admin UI under WooCommerce → Cart Tax Rules
• Works on classic cart/checkout AND WooCommerce Block Checkout
• No billing address required — tax is based on active currency only
• Compatible with WPML + WooCommerce Multilingual, WooCommerce Payments, and most other currency plugins
• HPOS (High-Performance Order Storage) compatible
• Clean uninstall — all data removed on plugin deletion

Example

• AUD rule: threshold = $500, rate = 10%
• Customer adds $200 AUD of products → 10% tax ($20) is added
• Customer adds $600 AUD of products → No tax (tax free)

Multi-Currency Support

CartTaxify detects the active currency automatically and applies the matching rule. It supports WooCommerce default (single currency), WPML + WooCommerce Multilingual, WooCommerce Payments multi-currency, and most other currency switcher plugins via the standard WooCommerce currency filter.

Important: Ensure WooCommerce native tax rates are cleared (WooCommerce → Settings → Tax → Standard Rates) to avoid double taxation.
