SARS Sets 2026 Auto-Assessment Window as Millions of Taxpayers Go Digital

The South African Revenue Service (SARS)  has confirmed that its 2026 auto-assessment process will run from 1 July to 12 July 2026. During this period, millions of taxpayers will automatically receive assessments based on information already available to SARS from third-party sources such as employers, medical schemes, and financial institutions. Taxpayers who are not auto-assessed, or who disagree with their assessment, will be able to file their returns from 13 July, with the final deadline for non-provisional individuals set for 23 October 2026.

SARS has introduced several enhancements to improve the 2026 tax filing experience. These include pre-filled third-party data such as investment and employment income, a simplified return format with clearer questions, dropdown options for approved medical aid schemes to reduce errors, the delivery of assessment notices via WhatsApp, and a new declaration alert system designed to reduce the likelihood of returns being flagged for verification. The aim is to make the process faster and more accurate for most taxpayers.

Despite these improvements, tax experts continue to warn that auto-assessments should not be accepted without careful review. According to TaxTim, the system can only work with the data it receives, meaning any income or deductions not reported by third parties will not appear in the assessment. This includes common items such as freelance or side-hustle income, rental income, foreign income, donations, medical expenses, home office costs, travel claims, and certain retirement annuity contributions.

Taxpayers are advised to carefully check whether all income, deductions, and personal details match their actual financial situation before accepting the assessment. If third-party data such as an employer’s IRP5 or medical aid certificate is incorrect, taxpayers cannot directly edit it on the return. Instead, the original provider must correct and resubmit the information to SARS. Only missing items that SARS does not already have on record can be added by the taxpayer when filing.

If a taxpayer does not respond to an auto-assessment, SARS treats this as agreement, and the assessment becomes final. Any refund of R100 or more is typically paid automatically within about 72 hours, provided there are no verification, compliance, or banking issues. If the taxpayer disagrees with the assessment, they must submit a corrected return through the appropriate filing channel before the deadline.

TaxTim, a South African tax service, has encouraged taxpayers to take a few minutes to review their assessments carefully rather than accepting them automatically. It also provides tools such as an auto-assessment checker and an AI assistant called TimAI to help taxpayers identify missing or incorrect information and ensure their returns are accurate before submission.
