Wife is under treatment for the last 4 years for muscular dystrophy Did not obtain medical certificate & didn't claim any deduction so far. Last fy-2017-18 expenses were much more. Now if i obtain it in ay 2018-19,can i claim deduction under 80DD or 80DDB or not? I never knew that deduction will be admissible in ay2018-19.please clarify. Thank you in anticipation.
