Kintsugi AI Tax

Kintsugi AI Tax connects your store to Kintsugi, a tax automation service. When tax calculation is turned on, the plugin asks your Kintsugi account for the tax on each WooCommerce checkout. Kintsugi uses the same order data to monitor where you owe tax and to prepare, file, and remit your returns. A Kintsugi account is required. The plugin connects your store to the Kintsugi service and does not calculate tax on its own. You can create an account at https://app.trykintsugi.com/. What the plugin does

• Calculates sales tax, VAT, and GST at checkout for orders in the United States, Canada, and the European Union
• Keeps your Kintsugi account up to date as orders and refunds change in your store
• Lets you turn tax calculation and webhook processing on or off from the plugin settings

What your Kintsugi account does

• Monitors your sales against economic nexus thresholds in each jurisdiction
• Registers your business in new jurisdictions
• Prepares, files, and remits your returns
• Stores exemption certificates for tax-exempt customers
• Supports back filing when you find past obligations

Which of these are included depends on your Kintsugi plan. Nexus monitoring is available on the free plan. Registration, filing, remittance, and tax calculation at checkout need a paid plan. Requirements

• PHP 8.2 or higher
• WordPress 6.8 or higher
• WooCommerce 10.0.0 or higher
• A Kintsugi account and API key
• WooCommerce REST API keys (Read/Write) when connecting the store from Kintsugi Data Sources

Coverage Checkout tax calculation covers the United States, Canada, and the European Union. For stores that ship elsewhere, Kintsugi imports and monitors your WooCommerce data, and checkout calculation is not applied outside those regions. Compliance Kintsugi helps your business meet its sales tax, VAT, and GST obligations. No plugin or service can guarantee legal compliance, and you remain responsible for your store's tax obligations. Kintsugi's service performs the calculation, registration, filing, and remittance work included in your plan. Known limitations
