Any medical expenses when paid is considered as part of taxable salary. If the employee submits proof of having incurred the expenditure towards medical treatment, the sum spent towards medical treatment or ₹ 15,000/-, whichever is less, is excluded from salary. The exclusion is on the basis of the proviso (v) to section 17(2) of the Income Tax Act. If the amount spent towards medical treatment is in excess of ₹ 15,000/- the excess (beyond ₹ 15,000) is not considered as a deduction. Effectively, the excess amount spent continues to remain taxable. If no proof of having incurred the expenditure towards the medical treatment is produced by the employee, the entire sum paid is considered as a perquisite. TDS under section 192 of the Act has to be deducted accordingly. In this case presuming that proof has been submitted any amount in excess of ₹ 15000 would be subject to TDS provided of course that this limit of ₹ 15000 has not been already exhausted earlier during the Financial Year
