For provisional taxpayers, the upcoming deadlines in early 2026 relate to income earned during the 2025 tax year (1 March 2024 – 28 February 2025). SARS opened the filing window in July 2025, with annual returns due 19 January 2026 and final provisional payments due 28 February 2026. January is therefore the final opportunity to verify your figures, update records, and ensure all allowable deductions are captured.
Accuracy has become critical as SARS moves deeper into an AI-powered enforcement model. The tax authority now uses machine learning and real-time data analysis to compare your filings with information from banks, employers, investment platforms, crypto exchanges, and beneficial ownership databases. These systems flag mismatches quickly, whether sudden wealth changes, lifestyle inconsistencies, or omitted income, leaving far less room for estimation errors or outdated record-keeping.
This shift helped SARS collect a record R2.155 trillion in 2023/24 and signals stricter, faster, and more precise compliance monitoring ahead.
Filing Accurately and Avoiding Penalties
- To minimise risk, maintain detailed records of all income sources and deductions, and use SARS eFiling to reduce calculation errors.
- Always review SARS auto assessments. If anything is incorrect, submit your own return.
- Filing late or underestimating income triggers penalties and may increase your audit risk in an automated compliance system.
Common Pitfalls to Avoid
- Not claiming what you are entitled to, including retirement annuity contributions, medical scheme tax credits and qualifying medical expenses, business-related expenses, age-based tax rebates, learnership allowances, approved donations, and travel deductions.
- Ignoring SARS notifications or accepting incorrect auto assessments.
- Underestimating taxable income to reduce the February payment.
- Overlooking rental income, investment earnings, freelance income, or cryptocurrency gains.
Being proactive helps prevent penalties and reduces the likelihood of SARS queries
