e-Invois / MyInvois
MyInvois is LHDN's national e-invoicing system, rolled out to businesses in phases. It is a real government system — but that also makes its name useful to scammers. Treat any message about e-invoicing "fees," "registration," or "penalties" with the same check as any other LHDN message: genuine correspondence comes from an @hasil.gov.my address, and LHDN's own fraud-alert page (hasil.gov.my/polisi-portal/peringatan-penipuan) is the authority on what its real notices look like.
