TaxZen for WooCommerce

Stop spending hours wrestling with WooCommerce tax tables. TaxZen for WooCommerce replaces the tedious, error-prone process of manually configuring tax rates with a guided 5-step wizard that gets your store tax-compliant in minutes.

🧙 5-Step Setup Wizard

Get from zero to fully-configured taxes in under 5 minutes:

1. Store Setup — Auto-detects your WooCommerce store country and currency (or set manually)
2. Product Types — Choose what you sell: Physical Goods, Digital Products, Services — each gets the correct tax class
3. Target Countries — Select the countries where you sell, with smart defaults for EU, NAFTA, and APAC regions
4. Rate Preview — Review every rate before it touches your store, with country-by-country breakdown
5. One-Click Apply — Push all rates to WooCommerce tax tables with a single click and two-step confirmation

Re-run the wizard anytime. TaxZen cleans up old rates automatically — no duplicates, no orphaned entries.
