Connect Salesforce with TaxJar to calculate, collect, and file sales tax with the right nexus rules, keeping tax data consistent from quote to order and across channels.
• Orders and customer ship-to addresses from Salesforce are sent to TaxJar for real-time sales tax calculation, with returned tax amounts written back to the originating order records.
• Product and line-item attributes in Salesforce are mapped to TaxJar tax codes where available; unmapped items fall back to default taxability rules defined in TaxJar.
• Transaction syncs create or update TaxJar records for finalized orders, with support for partial refunds and cancellations by issuing matching adjustment transactions.
• Sales tax jurisdiction is derived from validated destination address data; invalid or incomplete addresses are flagged, and calculation responses are logged for traceability.
• Idempotency keys and order identifiers are used to prevent duplicate transaction creation during retries, resyncs, or webhook replays.
• Sync ownership is split: Salesforce remains the source for order state, while TaxJar remains the source for tax rate logic and transaction-level tax reporting.

We map Salesforce order, shipping, product taxability, and customer location data to TaxJar’s API, then return the calculated tax back to the order record. The same flow can cover refunds and partial shipments when needed.
At minimum, TaxJar needs ship-to address, origin, item SKUs, prices, discounts, shipping charges, and exemption status. We also align your product and customer data so TaxJar can apply the right taxability and nexus logic.
Yes, we can separate channels using TaxJar transaction “provider” settings, warehouse origins, or custom mapping rules. This keeps reporting clean when you run multiple storefronts, brands, or sales streams.
We standardize rounding, discount allocation, and shipping tax logic across Salesforce objects so TaxJar and Salesforce land on the same numbers. We also add validation so edits don’t silently change tax after the order is confirmed.
