As the 20 October 2025 filing deadline approaches, SARS is urging non-provisional taxpayers to submit their annual income-tax returns to avoid penalties and interest. The filing window for non-provisional taxpayers runs until 20 October 2025, and SARS has thanked the roughly 80% of filers who have already submitted their returns.
What’s happening and why it matters
The tax authority has emphasised compliance and is using expanded digital checks and third-party data to validate returns. That means late or incorrect filings are more likely to be spotted, and administrative penalties can follow if a return is not submitted.
Key verified facts (quick reference)
Filing deadline: 20 October 2025 (non-provisional taxpayers).
Reported early filers: SARS has publicly noted around 80% of non-provisional filers have already filed (about six million auto-assessments included).
Refunds: SARS auto-assessed refunds of R100 or more are typically paid within 72 hours of notification, where the return and banking details are in order.
Administrative penalties: Failure to submit a return can trigger fixed-amount monthly penalties (ranging from about R250 up to R16,000 per month depending on taxable income) and can continue monthly until the return is submitted.
Interest on outstanding amounts: Interest applies to late payments; SARS publishes updated interest tables and these rates change over time, so check the official interest table before making assumptions.
Practical last-minute checklist
1. Log into eFiling or the SARS MobiApp and confirm your pre-populated details (IRP5/employer data). Filing electronically is the fastest way to process refunds and avoid admin penalties.
2. Verify income and deductions (medical aid, retirement annuities, allowable donations). Avoid claiming items you can’t substantiate — automated checks flag common discrepancies.
3. If you expect a refund, ensure your bank details are up to date so the auto-refund process can work. Refunds of R100 or more are typically paid within the 72-hour auto-assessment window.
4. Protect your profile: enable two-factor authentication on eFiling to reduce fraud risk.
5. If you can’t meet the deadline for a valid reason, review SARS guidance on extensions or remission — these are exceptional and require supporting evidence.
Freelancers & mixed-income earners — what to watch
Many people who do some freelance work may straddle filing categories. If your freelance or business income reaches or exceeds thresholds that require provisional registration, different dates and obligations apply. If you fall under the non-provisional rules, the 20 October cut-off applies — but if you’re unsure, register or ask a tax professional quickly. Keep clear invoices and digital records (SARS requires retention of supporting records for several years).
Tools and workflow tips
Use the eFiling wizard to declare “other income” fields for side gigs; consider lightweight accounting tools to export figures into your return. If VAT registration or business-class deductions apply, align those records with your income tax return to avoid mismatches in SARS data cross-checks.
Lessons from advanced digital tax administrations
Large, tech-forward tax administrations increasingly use automated invoice and transaction matching and real-time data feeds to reduce evasion and speed up refunds. Those system designs — automated assessments, mandatory platform reporting, and digital invoices — are models that other administrations look to when modernising compliance and taxpayer services. These trends explain why accurate digital records and timely eFiling matter more than ever.
