My medical aid is only deducted after PAYE. (i.e. Income - PAYE) = x less medical aid

My company insist that their calculations are correct. They only deduct my medical aid contribution after PAYE. As a result instead of my deduction being R10 000 to R11 000 odd I end up with at least R15000 plus deductions. Then they are adamant that when I do my tax returns I should get all that is due to me which is not true.

Yes, Medical Aid is no longer a deduction from income but rather a credit off the tax payable.
