The medical deduction allowed for the 2019 year of assessment is R310 per month for the first two members, and R209 per month for every additional member.
For taxpayers who belong to a medical aid, and pay their own contributions monthly, this usually means that the medical deduction allowed will lead to a refund on their tax.
This is not the case for taxpayers who receive their medical aid as a benefit on their income package. Thus, their medical aid is paid by their employer. The reason for this is that the medical deductions is taken into account on a monthly basis, when tax(PAYE) on salary is calculated. This means that the taxpayer gets the benefit on a monthly basis instead of once a year.
Also note, there is no allowable deductions for a medical insurance.
