A B2B client from Berlin enters their company number at checkout and sees the same amount with tax. A reseller from Florida doesn't understand why they're paying European VAT for a digital product. WooCommerce can calculate tax out of the box, but it can't remove it for specific customers, roles, or jurisdictions.

Six plugins in this roundup cover different tax scenarios: automatic VAT number validation through VIES for B2B in the EU, exemption by user roles, manual document workflow with an admin panel, full OSS/IOSS compliance, and US sales tax through Avalara. Each has been verified for 2026.

💡 Quick overview:

• Choose your scenario: B2B in the EU with VIES validation, exemption by user roles, or manual document workflow with an application form
• Install the right plugin and configure exemption rules for the needed roles, users, or countries
• Test checkout: VAT number validates through VIES, tax is removed automatically, client sees the net amount

⁉️🤔 Frequently asked questions

Do I need a separate plugin if I only sell within my own country?

If you sell only B2C within one country without B2B clients with VAT numbers, WooCommerce handles it out of the box. As soon as you have at least one B2B client or buyer from another tax jurisdiction, a plugin becomes necessary.

Is it mandatory to verify VAT through VIES?

Yes, if you sell B2B in the EU. VIES (VAT Information Exchange System) is the official European Commission registry. Without verification, the risk falls on the seller: if the client's VAT number turns out to be invalid and tax wasn't charged, the store is liable. EU VAT Number, EU/UK VAT Manager, and EU/UK VAT Compliance Assistant Pro work with VIES directly.

Which plugin to choose for the US market?

WooCommerce AvaTax from Avalara. The US has no unified VAT: instead there's sales tax different in every state, county, and city. AvaTax determines the rate automatically by customer address and prepares data for filing. Other plugins in this roundup are oriented toward the European VAT model.

Can I use multiple plugins simultaneously?

Not recommended. Two plugins changing tax calculation logic can conflict: duplicate fields at checkout, remove tax twice, or cancel each other's exemptions. Choose one plugin for all your scenarios.

What to do if EU/UK VAT Manager is closed on WordPress.org?

Plugin is temporarily closed since April 2026 and undergoing review. Existing installations work. If you're just choosing a plugin, consider EU/UK VAT Compliance Assistant, covers the same scenarios and is actively maintained.

How does AvaTax differ from European VAT plugins?

AvaTax works as an integration with the external Avalara service, which calculates taxes on its side. European VAT plugins work locally: determine country, insert rate, validate number through VIES. AvaTax covers the US and over 80 countries, European plugins are tailored to the EU and UK VAT model.

💎 What to install in 2026: selection matrix

For B2B in the EU with auto-validation through VIES: go with EU/UK VAT Compliance Assistant Pro ($55). Full cycle from geolocation to CSV report for OSS/IOSS, regular updates. Need only VIES validation without full compliance: EU VAT Number ($29) covers the task with one field.

Budget is limited, VIES not needed: Tax Exemption for WooCommerce by RelyWP covers exemption by user roles for free. Manual document workflow with certificates and applications: Tax Exempt for WooCommerce from WooCommerce.com ($59).

US market: WooCommerce AvaTax, no alternatives. Thousands of sales tax jurisdictions can't be calculated manually.
