Tax‑Proof Coupons for WooCommerce

Description

Tax‑Proof Coupons for WooCommerce adds a simple checkbox “Apply coupon after tax” to the coupon edit screen. When enabled on a fixed-cart coupon, the plugin converts the gross coupon value you enter into the correct net discount and applies it across the cart items—guaranteeing the exact gross amount is deducted, no matter the VAT rate or customer location.

Installation

  1. Upload the tax-proof-coupons folder to /wp-content/plugins/.
  2. Activate the plugin from the Plugins screen in WordPress.
  3. In WooCommerce Coupons, edit a fixed-cart coupon and check Apply coupon after tax.

FAQ

Why is this needed?

By default, WooCommerce adjusts fixed-cart coupons by the current VAT rate, causing the discount to vary by customer location. Tax‑Proof Coupons ensures a fixed gross coupon value remains fixed across all taxes.
