SST coding on recurring charges in Malaysian billing applications
A product marked “software, overseas, no SST” will bill that way forever. Recurring charges inherit the first person’s tax decision.
Subscription catalogues are built by product managers. Tax codes are often a drop-down chosen once. For a Malaysian registrant, that choice repeats on every renewal. A wrong exemption is not a one-line invoice error; it is a stream.
We do not give tax opinions. We test whether the codes in the billing application match the matrix finance and the tax adviser signed, and whether changes to that matrix were applied to existing subscriptions or only to new ones.
Place-of-supply and customer-location fields deserve the same attention. A billing application that stores a card-issuing country but invoices a Malaysian billing address will apply whichever field the tax engine was pointed at. That pointer is a configuration fact, and it should be in the working papers.
When we raise SST findings, we raise them as billing-application facts for management and the tax adviser to interpret. The financial-audit question is whether the invoices and the tax reports can be reconciled to the same product catalogue.
