Tax season can feel overwhelming for many South African employees, especially those filing for the first time or dealing with multiple income sources. This step-by-step guide is designed to demystify the SARS eFiling process and help you complete your ITR12 return accurately and confidently. The guide covers everything from registering on eFiling to understanding your IRP5, identifying allowable deductions, and submitting your return before the deadline. Written in plain language with South African examples, this resource can assist employees in understanding which expenses may be deductible — including home office costs for remote workers, medical aid contributions, retirement annuity deductions, and travel allowances. It also highlights common errors that may trigger a SARS audit and how to avoid them, as well as what to do if you receive a verification letter. Whether you are a salaried employee, a part-time worker with additional income, or someone who has never filed before, this guide may help you navigate the 2026 tax season with greater confidence and potentially maximise your refund within the bounds of SA tax law.
