Knowledge Base & Operational DocumentationWhy Does CS-Cart Show a Different Tax Amount After the Customer Signs In?
Tax can change after sign-in because a saved address, customer tax exemption, group setting, or location rule becomes available. The change can be legitimate but should be understandable before the customer submits the order.
What to check
Compare guest and account address, tax status, customer group, product tax settings, shipping destination, and tax display configuration. Test with a known exempt and non-exempt account and inspect the order calculation.
Recommended next step
Make tax assumptions visible and confirm the final amount before order placement. Validate account and guest flows after tax configuration changes and consult the appropriate tax owner for policy questions.
