Connect Magento 2 and SpeedTax to calculate real-time sales tax by address, apply the right rules at checkout, and reduce filing errors across states.
• Magento (Adobe Commerce) sends cart or order context to SpeedTax for real-time tax quotes, including ship-from, ship-to, line items, discounts, and shipping charges.
• SpeedTax returns jurisdiction and tax amounts per rate bucket, which are mapped back to Magento totals and stored with the order for traceability.
• Order lifecycle events (place order, invoice, credit memo) trigger tax recalculation or confirmation calls, depending on whether totals or addresses changed.
• Customer tax exemption data and certificate identifiers are mapped to SpeedTax exemption inputs when present, and persisted on the Magento customer or order record.
• Tax rounding, currency precision, and inclusive or exclusive tax settings are aligned to Magento tax configuration so stored totals match displayed totals.
• API requests and responses are logged with correlation IDs, and failures fall back to Magento error handling paths to prevent silent mismatches.

We implement the SpeedTax connector, map Magento addresses and order totals to SpeedTax requests, and validate tax results across cart, checkout, and order creation.
Yes – we can pass customer tax class, exemption flags, and related attributes to SpeedTax so exempt orders stay exempt from checkout through invoicing.
That’s the goal of the setup – tax decisions are carried through the order lifecycle, including invoicing, partial refunds, and cancellations, with the same SpeedTax rules applied.
Yes – SpeedTax calculates by ship-to address, and we can configure Magento store views, customer groups, and product tax classes to route the right context per store.
We run staging test cases for edge scenarios like address changes, mixed carts, discounts, shipping taxability, and refunds, then reconcile results against expected SpeedTax responses.
