What happens if I miss the SARS deadline? Here’s all to know

Why SARS won’t pay or collect refunds under R100 — What it means for your 2025 tax return
South Africans have until midnight tonight to file their income tax returns or risk facing steep administrative penalties from the South African Revenue Service (SARS). The revenue agency has reiterated that non-provisional taxpayers who fail to meet the 20 October 2025 deadline will be subject to fines and possible interest charges.
According to SARS, the filing process has been made easier and faster through digital innovations, including its Auto Assessment system, online filing tools, and improved helpline support. The agency says these upgrades were designed to remove barriers and ensure a smooth experience for taxpayers.
In an official statement, SARS emphasized that failure to meet the deadline is a serious offence. “The Commissioner urges all taxpayers not to abdicate their tax obligations. Non-compliance will result in administrative penalties and interest charges,” the agency warned.
Compliance or Consequences
SARS added that it is stepping up enforcement as part of its commitment to encourage voluntary compliance while also “identifying and acting against” defaulters. The agency confirmed that it has already processed over 7.9 million submissions, representing nearly 80% of non-provisional taxpayers.
Tax season officially kicked off on 7 July 2025, and different categories of taxpayers were assigned staggered deadlines to ensure efficiency. For those yet to file, tonight marks the final opportunity to submit without facing consequences.
Penalties Can Be Costly
Experts have warned that ignoring the filing requirement — even when no tax is owed — can prove financially damaging. According to Tax Consulting South Africa, taxpayers could face monthly penalties ranging from R250 to R16,000 per outstanding return.
“Many people wrongly assume that if they don’t owe SARS anything, they don’t need to file,” the firm said. “But that misconception can lead to retrospective assessments, penalties, and unnecessary legal trouble.”
Tax specialists recommend that even individuals who earn below the taxable threshold file their returns to keep their tax records updated, especially since SARS may still require proof of income or employment details in future audits.
Digital Transformation and Support
In recent years, SARS has made major strides toward digital transformation. Its Auto Assessment feature, available on eFiling and the SARS MobiApp, automatically generates tax returns based on verified third-party data, saving taxpayers time and minimizing human error.
The agency also provides access to call centers and walk-in branches nationwide for those needing assistance with last-minute submissions.
As the midnight deadline approaches, SARS continues to urge citizens to file voluntarily rather than risk enforcement action.
“In a country where tax compliance is not just a legal obligation but a civic responsibility,” a senior tax officer noted, “meeting your deadline reflects your contribution to the nation’s growth.”
