Some basic difference between two Sec.Sec 80DD – Deduction is allowed to the Caretaker of the dependent disable person.Sec 80U – Deduction is allowed to the assessee himself.Sec 80DD – Either he has to make some medical expenses on the disable or deposit the amount for the disable to the Insurance Co.Sec 80U – Being disability is the only condition.
Assessee can take the benefit of either of the two secs whichever is more beneficial to him but once the assessee has taken the benefits under Sec 80DD for the disability of the person than the another assessee who is self-suffering from the disability can't take the benefit for the same under Sec 80U.
