What’s New in Filing Season 2025
- Expanded Auto Assessment coverage: now includes rental and freelance income data
- Enhanced AI Virtual Assistant: 24/7 tax support chat with natural-language insights
- USSD feature upgrades: faster balance queries and SMS notifications
- API access for developers: integrate SARS data into accounting software seamlessly
These updates reflect SARS’s drive toward a fully integrated, data-driven tax ecosystem. Expect more pre-populated fields, proactive alerts and audit-prevention tools.
Auto Assessment: Pre-Populated Returns
SARS’s Auto Assessment pulls data from employers, banks, medical aids and retirement funds to build your return. If all figures look correct, there’s no need to file manually – your assessment is final.
Spot an error? Log into eFiling or the MobiApp, correct the details and re-submit before your deadline. Any refunds above R100 are paid within 72 hours, thanks to streamlined processing.
Digital Channels: File Anywhere, Anytime
- eFiling portal: redesigned dashboard with Express Tabs for quick edits
- SARS MobiApp: fingerprint or Face ID login, push notifications and in-app support
- WhatsApp service: text “Hi” to 0800 117 277 for instant FAQs and status checks
- USSD code (1347277#): basic filing status and balance inquiries without data
With these options, you can file at your desk, on the train or between meetings. SARS has optimized each channel for mobile data constraints and high-traffic volumes.
Who Must File and Who Is Exempt
You’re exempt only if all these apply:
- Total income under R500,000 from one employer
- No rental, investment or side-gig earnings
- PAYE correctly deducted at source
- No additional deductions beyond standard allowances
If you fall outside any of these criteria, filing is mandatory. Even if you owe zero tax, a return keeps your tax record clear and prevents future queries.
Tech Tips for a Smooth Filing
- Update your personal and banking details on eFiling early.
- Review your auto-assessed draft before accepting it as final.
- Use Express Tabs on the portal to navigate directly to sections you need.
- Store digital copies of receipts and statements for at least five years.
- Enable two-factor authentication on the MobiApp for extra security.
These simple steps can reduce errors, speed up refunds and guard against identity fraud.
Behind the Scenes: AI, Data Matching and Security
Machine learning models now flag anomalies by cross-referencing global financial data and local transactions. SARS’s data-matching engine ingests millions of records daily to detect under-declared income. All your submissions are protected by end-to-end encryption and continuous penetration testing.
Beyond Filing: Automation and Integration
- Developers can leverage SARS’s new API to pull tax data directly into accounting platforms.
- Automate expense categorization with third-party bookkeeping tools linked via webhooks.
- Use cloud storage connectors for real-time receipt uploads and audit trails.
This is the year to move from manual spreadsheets to fully automated tax workflows.
