The Disability Tax Playbook

---

 Most South Africans significantly underclaim their disability tax benefits. Not because they're ineligible, but because the rules are complex and widely misunderstood.

Not every medical condition automatically qualifies. SARS applies a specific standard — and understanding it is the essential first step to a valid, optimised claim. All three criteria below must be met:

• Moderate to severe - Mild conditions typically do not meet the threshold for the disability tax deduction.
• Expected to last longer than 12 months - The condition must be ongoing — not temporary or short-term in nature.
• Diagnosed by a qualified medical practitioner - The diagnosis must be formally documented by an appropriate healthcare professional.

 Many taxpayers only capture the most obvious costs. A fully optimised submission includes the complete range of qualifying expenses — often revealing significantly more than initially anticipated. 

• Medical Aid Contributions - The medical aid contributions for the entire family can be included in your claim.

• Medical Expenses - Out-of-pocket medical expenses for the entire family can be claimed. This includes doctors' visits, prescription medication as well as therapy (eg. OT, Speech and Pysio)

• Disability Expenses - These include all non-medical expenses, specifically related to the diagnosis and can include assistive devices, caregivers, specialised schooling and travel expenses

 The burden of proof for the Section 6B Disability Tax Claim is exceptionally high. This means that SARS will not allow a claim if it is not substantiated with ALL the required documents. Here is a list of some of the supporting documents that may be required by SARS:

• Medical Aid Tax Certificate
• Detailed Tax Report from the Medical Aid
• Invoices or statements from the doctors or service providers for each amount claimed.
• Proof of payment of each amount claimed on the taxpayer's bank statement.
• Employment contract & payslips for caregivers
• Logbook for disability related travel expenses

 Each of these errors results in a claim that is lower than it should be — and in most cases, the taxpayer has no idea it happened. 

• Underclaiming expenses - Only capturing obvious costs while missing a range of qualifying deductions SARS allows. 

• Incorrect categorisation - Placing expenses under the wrong categories can reduce or invalidate entire portions of the claim. 

• Submitting incomplete documentation - Missing supporting records give SARS grounds to query or reject your submission. 

• Assuming previous claims were correct - Prior years are often underclaimed — and in many cases, they can still be revisited and corrected. 

 A fully optimised disability tax claim requires attention to both documentation and strategy. Here is what a strong, audit-ready submission looks like: 

•  Ensure the ITR-DD is correctly and completely filled in 

•  Capture all qualifying expenses — not just the most visible ones 

•  Review prior tax years for underclaimed amounts 

•  Structure your submission properly to withstand a SARS audit 

  While it is possible to submit your current year disability tax claim on your own, these submissions are often not fully optimised. The real complexity arises when dealing with backdated claims, disputes, or the resubmission of prior years’ returns, where SARS requirements become far more technical. For this reason, it is important to work with a qualified tax practitioner who has specific experience in disability tax claims, to ensure your claim is accurate, compliant, and maximised.  

Taxpayers who go it alone typically encounter one or more of the following:
