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.
