What is Section 20A Ring-fencing?
Section 20A of the Income Tax Act in South Africa addresses the ring-fencing of assessed losses for individuals conducting certain trades. Previously, losses from those trades could be offset against other income (e.g., salary or investment income), but under ring-fencing, these losses can only be carried forward and offset against future income from the same trade. For example, someone operating a rental business or creative enterprise would use losses in that trade only when that same trade makes income. (sars.gov.za)
Key Change as of 1 March 2026
For years of assessment starting on or after 1 March 2026, the threshold that triggers this ring-fencing has been lowered. Now, assessed losses can be ring-fenced when a taxpayer’s marginal tax rate reaches 39%, rather than the previous benchmark of the maximum marginal rate (45%) of tax. This means more taxpayers with higher incomes may be affected. (sars.gov.za)
Summary of Conditions
To determine whether ring-fencing applies, the following must be satisfied:
- Step 1: The taxpayer’s adjusted taxable income (income plus assessed losses and previous carry-forwards) must reach the income level at which a 39% marginal rate applies. (sars.gov.za)
- Step 2: Either:
- the “three-out-of-five-years” test (losses in 3 of last 5 years), or
- trade is listed as a ‘suspect trade’ (such as renting vehicles, creative arts, farming part-time, etc.) under section 20A(2)(b). (sars.gov.za)
- If those are met—and the taxpayer does not demonstrate a reasonable prospect of making taxable income from the trade in the near term—ring-fencing kicks in. (sars.gov.za)
Practical Impacts & Examples
| Type of Taxpayer | Scenario | Effect of the Change |
|---|---|---|
| High-Income Creative Freelancer | Freelancer makes R1 million income subject to 39% rate, also generates losses from creative trade in 3 of past 5 years | Losses from the creative trade must now be ring-fenced—cannot offset against salary income. |
| Part-time Farmer with Lower Income | Farmer with income below the 39% threshold, no losses in many past years | Ring-fencing does not apply—losses can still offset other income. |
Actionable Advice for Taxpayers & Advisors
- Check your marginal tax rate: Look at your 2025/26 and upcoming 2026/27 assessments—are you paying or projected to pay ≥ 39%? If so, ring-fencing may soon affect you.
- Maintain loss records by trade: Keep good details showing how losses relate to specific trades—as trader activities in multiple niches might be treated separately.
- Review your history: If you had losses in 3 of the 5 years for a trade, start modeling out how ring-fencing would affect your tax liability.
- Plan for income generation: To avoid having losses go unused for many years, consider strategies to ensure at least some income arises from the trade—possibly adjusting scale, seeking contracts, or modifying business model.
- Consider trade classification: If your activity is borderline (e.g., creative arts, partial farming, rentals), evaluate if shifting status (e.g., corporate structure or full-time dedication) changes your treatment.
Why This Change Matters for Compliance & Planning
- More widespread impact: By lowering the trigger threshold, more individuals are drawn into the ring-fencing regime.
- Cash flow & tax liability shifts: Ability to offset losses immediately against other income decreases, raising net taxable income and possibly withholding, provisional tax demands, or PAYE liability changes.
- Strategic adjustments: For those in suspect trades, integrating multiple income streams, formalizing operations, or changing business structure might be necessary to optimize tax outcomes.
Bottom line: If you’re an individual with trade losses and a higher income, section 20A demands careful planning. Understand your income levels, track your losses per trade, and evaluate whether ring-fencing will reduce opportunities to offset non-trade income.
