About this plugin
Tax compliance is a full-time job. It shouldn’t be yours. VAT IT Tax Engine connects your WooCommerce store to the VAT IT compliance platform: every order gets the right tax at checkout, calculated in real time from the customer’s actual address.
Best for merchants selling into the US and internationally who want managed tax compliance from a global provider, not just a rate lookup.
A VAT IT account is required before you connect. Contact our team to get set up; once your account is ready, connecting your store takes minutes.
What’s included
- Real-time tax calculation. The right sales tax and VAT for every transaction, across jurisdictions, so your customers see accurate totals at checkout. US rates are resolved from the full address, down to state, county, city, and district level.
- B2B handling. Customer VAT numbers are picked up from your checkout and included in the calculation for correct business-customer treatment.
- Zero-friction setup. Connect through WooCommerce’s own secure authorization screen in one click. No API keys to copy and paste, and your checkout experience stays exactly the same.
- Your rules, your scope. US Addresses Only mode lets the engine handle US sales tax while your own WooCommerce settings apply elsewhere. Sandbox Mode lets you test everything against a sandbox account before going live.
- Safe rollout with Test Mode. List a few test customers and only they get engine-calculated tax, recorded as estimates rather than invoices. Every other customer checks out exactly as before, and order reporting is paused. Untick one box to go live for everyone.
Built for WooCommerce
No generic middleware. The plugin lives inside WooCommerce, works with both the block-based and classic checkout, and handles items, shipping, coupons, and whole-order discounts exactly as WooCommerce allocates them. Until you connect, it touches nothing; if you disconnect, it cleans up after itself and your store returns to its previous tax setup.
Backed by a compliance provider, not just software
VAT IT is a global tax compliance group serving businesses in over 100 countries. The Tax Engine is the same platform our compliance teams work with, which means the numbers at your checkout and the numbers in your filings come from one source.

- What it is used for: authorizing your store, calculating tax at checkout, and receiving orders as they are placed, for tax compliance reporting.
- What data is sent and when: your store URL and store name when you connect. At checkout, the customer’s billing/shipping address, name, email, VAT/tax number (if provided), and cart line items (products, quantities, prices) are sent to calculate tax. When an order is created or updated (including refunds and status changes), the order details are delivered to the platform via WooCommerce webhooks, signed with a per-store secret. No data is sent before you connect your store.
