Dear Sir,
Hope you are doing well !!
As per an amendment in the Budget 2018, tax exemption on medical reimbursement amounting to INR 15,000 and transport allowance amounting to INR 19,200 in a financial year have been replaced with a standard deduction of INR 40,000.
This amendment became applicable from FY 2018-19 (i.e. starting 1st April 2018).
From FY 2019-20 onwards, the standard deduction has been raised to Rs. 50,000. (Amended in Budget 2019).
So, even if there is some reimbursement of medical expenses on normal treatment and medicines, you will not be able to get any tax benefit as the reimbursed amount will be treated as perquisite and will be taxed accordingly.
However, apart from this, tax benefits on account of medical expenditures may be availed as per other sections or income-tax rules.
