## What’s New in Filing Season 2026 (South Africa)
### Auto Assessments Expanded
From **1 to 12 July 2026**, SARS will issue **auto assessments** for eligible individual and now **provisional taxpayers** based on third-party data including income from employers, medical schemes, banks and retirement funds.

### Section 20A Ring-fencing Shifts
For years of assessment starting **1 March 2026**, ring-fencing of assessed losses based on the marginal tax rate of **39%** applies (versus only above the 45% rate under previous law). This affects taxpayers with trades that generate recurring losses.

### Required Traveller Declarations & Changed Customs Procedures
Since **1 July 2026**, travellers entering or leaving SA must submit an **online traveller declaration** via the SARS Customs Online Traveller Declaration Portal, or through mobile app or QR codes. ([sars.gov.za](https://www.sars.gov.za/businesses-and-employers/government/government-connect-issue-36-july-2026/?utm_source=openai))
SARS also revised **sample documentation** for commercial goods under Customs & Excise effective 1 July 2026, clarifying owner liability and provisions for duty payment deferral. ([sars.gov.za](https://www.sars.gov.za/whats-new-at-sars/3/?utm_source=openai))
## Practical Compliance Tips
* Review auto assessment notices carefully. Disagree? You can still file amendments by the provisional taxpayer deadline (22 January 2027). ([sars.gov.za](https://www.sars.gov.za/businesses-and-employers/government/government-connect-issue-36-july-2026/?utm_source=openai))
* Keep accurate, auditable records of expenses—especially where ring-fencing applies.
* For travellers or businesses with cross-border movements, ensure correct declarations to avoid hold-ups or penalties. Use official SARS channels. ([sars.gov.za](https://www.sars.gov.za/businesses-and-employers/government/government-connect-issue-36-july-2026/?utm_source=openai))
* Update any business or personal address, email, banking info so third-party data syncs correctly. Mismatches may lead to wrong auto assessment entries.
## Deadlines at a Glance
| Deadline | What’s Due |
|----------|--------------|
| 1–12 July 2026 | Auto-assessment notices issued for eligible taxpayers. |
| 13 July 2026 | Non-provisional individuals not auto-assessed may start submitting returns. |
| 22 January 2027 | Deadline for provisional taxpayers and entities to submit their returns. |
## Example: A Provisional Taxpayer Adapting
A photographer who runs a side business and earns income from events and online sales qualifies as a provisional taxpayer. Expect an auto-assessment for their base income streams. They'll have to verify it and then include business income manually if needed. Losses from event business may now be ring-fenced if taxable income flows into higher marginal tax zones. Stick to tight record-keeping.
**Bottom line:** Filing Season 2026 introduces both relief (more automation) and responsibility (new thresholds, rules). Active vigilance and good documentation will ensure compliance without surprises.
