Can I claim a deduction for medical aid premiums above the tax credit?

Yes. If your annual medical aid contributions exceed three times the annual MTC, the excess qualifies as additional medical expenses. SARS allows a credit of 25% of these excess contributions for taxpayers under 65, or 33.3% for those 65 and over or with a disability. Out-of-pocket medical expenses not paid by medical aid also qualify under the additional expenses calculation.

Is the Medical Tax Credit refundable?

No. The MTC is a non-refundable credit — it can reduce your tax liability to zero but cannot create a refund on its own. If your total tax liability after other deductions and credits is already zero, the MTC provides no additional cash benefit.

A realistic South Africa planning example

Use these sample inputs as a quick scenario test, then change one variable at a time to compare outcomes.

Monthly Medical Aid Premium (R)

Number of Additional Dependants

Annual Income (R)

R400,000

After entering these figures, review monthly mtc, annual tax credit and additional credit together rather than in isolation — each metric tells a different part of the story. Then rerun the tool with one input adjusted to see which variable has the biggest effect on all three outputs before you settle on a plan.

How to read your results

Monthly MTC

Use this metric to compare scenarios side by side and understand how changes in the key inputs drive the final outcome. If the figure surprises you, isolate one variable at a time and rerun the calculation to identify which assumption is responsible.

Annual 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 or a recommendation to make a tax decision.

Additional Credit

Total Annual Credit

This is the headline outcome of the calculation, but it is most useful when read alongside the supporting metrics below it rather than in isolation. Try changing one input at a time and watching how this total moves to understand which driver has the biggest impact.

Monthly Tax Saving

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

Method & assumptionsAuthoritative sources

This calculator estimates the SARS Medical Tax Credit (MTC) for the 2024/25 tax year. The primary MTC is R364 per month for the main member plus R246 per month for each additional dependant registered on the scheme — these amounts are fixed by SARS and apply regardless of the actual premium paid. The additional medical expenses credit applies when annual premiums exceed three times the annual primary MTC: the excess is multiplied by 25% (for taxpayers under 65 without a disability) or 33.3% (for those aged 65 and over, or with a qualifying disability). This simplified model uses annual premium versus three times the annual MTC as the trigger for the additional credit. Out-of-pocket expenses not reimbursed by medical aid are not included in this calculator but can further increase the additional credit when included in your ITR12 return.

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.
!Forgetting location-specific taxes, fees, eligibility rules or payroll deductions where they apply.
!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.
Use the result to prepare better questions for a lender, provider, adviser or employer rather than treating it as a final answer.
