Wrong VAT on every transaction isn't just a configuration problem β it's a compliance problem. Overcharging loses customers. Undercharging means you owe HMRC the difference. We fix the setup and get it right.
This is a legal issue, not just a technical one. If your store has been undercharging VAT, you're still liable to pay HMRC the correct amount β even if you didn't collect it. The sooner it's fixed, the smaller the exposure.
No fix? You pay nothing.
Most WooCommerce VAT problems look like a configuration annoyance. In practice, they create real legal and financial exposure.
WooCommerce VAT errors almost always fall into one of two categories β and each has very different consequences.
WooCommerce applies 20% VAT to products that should be zero-rated or exempt. Common with children's clothing, food items, books, disability aids, and certain services. Customers are paying more than they should β which damages conversion and trust.
WooCommerce applies 0% or no tax to products that should carry 20% VAT. Often caused by a misconfigured tax class, a plugin setting applied in error, or a migration from a platform with different tax defaults. The store appears cheaper β but you owe HMRC the difference on every order.
Post-Brexit, UK VAT rules for EU and international customers changed significantly. Many WooCommerce stores are still applying UK VAT to EU orders where local destination VAT or zero-rating should apply. This creates compliance exposure in both the UK and EU.
B2B customers who provide a valid VAT number should have VAT removed from their orders (reverse charge mechanism). WooCommerce doesn't handle this out of the box β it requires correct configuration or a plugin. Many stores simply never set it up.
WooCommerce needs to apply the correct rate to every product class. Getting this wrong is the root of most VAT problems.
VAT configuration in WooCommerce has many layers β tax classes, product assignments, display settings, location rules, and plugin interactions. We check all of them.
We review your WooCommerce tax settings, product tax class assignments, shipping tax settings, and any tax plugins. We map what your store is actually charging against what it should be charging.

β± Confirmed before we closeA UK children's clothing retailer came to us after a customer queried why they were being charged VAT. Children's clothing is zero-rated in the UK. Their WooCommerce store had been charging 20% on every order since launch β eight months earlier.
The developer who set up the store had enabled tax but only configured the standard 20% rate. No zero-rate class was created. Every product defaulted to standard rate. We created the correct tax classes, reassigned all products, and verified the configuration across multiple checkout scenarios. We also provided a report for their accountant summarising the period affected.
"We had no idea our products were being charged VAT at all. The fix was done the same day and we got a clear summary for our accountant explaining everything that had been wrong."
