80D claim for payment paid by parent

Yes, you can claim the benefit of Section 80D for a senior citizen for the amount of Rs. 50,000 paid by cheque by your parent, even if your parent has not claimed it in their return.

 Section 80D allows an individual to claim a deduction for medical expenses incurred for themselves or their dependents, including parents.

Since your parent has not claimed the deduction, you can claim it as long as you have the necessary documents to support the expense. 

To claim the deduction, you will need to meet the following conditions:

 1. The payment should be made by cheque.

2. The payment should be made to a registered insurer or a licensed insurer. 

3. The premium should be paid for a health insurance policy that covers your parent. 

4. Your parent should be a senior citizen (above 60 years). You will also need to obtain a receipt or a certificate from the insurer that confirms the payment of the premium. You can then claim the deduction in your income tax return. 

However, please note that the deduction is subject to a maximum limit of Rs. 50,000 for senior citizens.

 Additionally, you should also check the income tax laws and regulations for any changes or updates before claiming the deduction.
