- HASiL’s SDK 1.0 release notes confirm that TIN and BRN (Business Registration Number) validation will be added from 1 August 2026 to the Validate Taxpayer’s TIN API, improving buyer data accuracy for e-invoice submissions. [sdk.myinvo…sil.gov.my]
- Recent SDK updates also tighten field validations: State Code 17 is now restricted to consolidated e-invoices issued in Malaysia or transactions outside Malaysia; scientific notation is no longer supported in amount fields — all values must use standard numeric format. [sdk.myinvo…sil.gov.my]
- Operational action: Start buyer master-data clean-up now. Collect accurate BRNs, align buyer records with HASiL data, and test validation logic before the August production change.
