Do not fall prey to expensive SARS fines. Businesses that utilise registered payroll compliance services in South Africa can rest assured that each employee has a Tax Reference Number (TRN).

Ensure Accurate Employee Income Tax Numbers

With Home Affairs and Labour audits on the rise, local businesses must comply with statutory requirements. Legally, SARS requires a valid 10-digit TRN for everyone on your payroll, regardless of immigration status. Even employees who fall below the personal income tax threshold must be registered with SARS by the employer.

Register Foreign National TRNs

A core duty of any South African payroll service is ensuring all Foreign National employees have valid SARS tax registrations captured on your company’s payroll system. To maintain strict compliance, employers must register a TRN using a passport, asylum permit, or official visa.

Staff ID Requirements—Payroll Pitfalls

SARS has indicated that TRNs are mandatory. Failing to submit accurate ID, passport or asylum numbers fails your entire EMP501 submission. This invites costly SARS penalties and can flag your business for an audit.

Meanwhile, the Department of Employment and Labour (DoEL) is tightening enforcement on businesses employing undocumented foreign nationals. The proposed Employment Services Amendment Bill (ESAB) threatens hefty fines for both first-time contraventions and repeated non-compliance. While not yet law, it indicates where workplace regulation is heading.

TRN Validation Options for SME Payroll Compliance

Organisations have several options to handle TRN registration and history checks:

  • e@syFile™ Employer: For individual (ITREG) or bulk (Bundled ITREG) registration.
  • eFiling TRN Registration: Allows up to 200 employee registrations per batch.
  • TRN Enquiry Services: Read full details in the SARS TRN Enquiry Services Guide.
  • Manual Staff TRN Registration: Appointment at a SARS branch is required for non-digital applications.

Note: SARS will only provide a tax number to an authorised third party, as detailed in the SARS Tax Number Guide.
