Guide to submit your individual income tax return (ITR12) via the SARS MobiApp

Table of Contents


SARS is committed to making it easy and simple for taxpayers to comply. One of the taxpayer’s compliance responsibilities is to submit their income tax return (ITR12) to SARS during the filing season or at the end of the financial year. To make it simpler for taxpayers to submit their income tax (ITR12) return, SARS digital channels has introduced the SARS MobiApp, which can be installed on your smart mobile phone or device.

This webpage demonstrates how taxpayers can navigate the SARS MobiApp for the purpose of submitting their income tax return to SARS. The webpage also includes functionalities that may be utilised when filing income tax returns, such as how to respond to duplicate income tax certificates (IRP5) or how to view tax assessments before an official return is submitted.  Additionally, where SARS has engaged and requested supporting documents, there is a section that demonstrates how to upload the requested supporting documents.


Income tax is imposed under the Income Tax Act No. 58 of 1962. It is a tax levied on all income and profit received by a taxpayer (which could include individuals, companies, and trusts). Collecting taxable income is a SARS mandate, inter alia by assisting the citizens of South Africa in complying with their tax responsibilities. One of the compliance requirements for individuals is to file or submit the personal Income Tax (ITR12) return every year. The completion and submission of the ITR12 return are to determine whether the taxpayer is indebted to pay any taxes or eligible for a tax refund.

Various SARS service channels are available in which taxpayers can file/submit their return. These service platforms, amongst other duties, ensure that taxpayers are serviced efficiently and the information pertaining to their tax affairs are up to date, accurate and credible. This ultimately results to more reliable and credible assessments. The SARS MobiApp is one such service platform within the SARS digital domain.
