How to read your results

Medical Tax Credit (Section 6A)

Review this figure alongside gross income and the local tax rules that apply to you. It is a planning estimate, not a filing result.

Total Medical Tax Credit

Review this figure alongside gross income and the local tax rules that apply to you. It is a planning estimate, not a filing result.

Common mistakes

  • Using an assumption that is not supported by a current local quote, bill, statement or official source.
  • Treating a generic estimate as a lender, provider, payroll or tax authority decision.
  • Mixing monthly and annual inputs without converting them consistently.
  • Testing only one scenario instead of checking how a cautious assumption changes the result.

What to do next

  • Run a second scenario with a cautious assumption so you can see the downside clearly.
  • Compare the result with the related calculators below before making a decision.
  • Check current local rules, eligibility and provider terms before applying or committing money.
  • Keep a record of the assumptions so you can update the estimate when a quote, bill or pay figure changes.

Questions people ask

Section 6B provides relief for out-of-pocket medical costs that exceed a threshold set at four times your annual Section 6A credit. For taxpayers under 65, a 25% credit applies to qualifying expenses above that threshold. For taxpayers aged 65 or older, the credit is more generous — 33.3% applies to all qualifying medical contributions and out-of-pocket expenses with no lower threshold. Qualifying expenses include medical aid contributions not covered by the Section 6A credit and approved medical costs not reimbursed by your medical aid scheme.
