Do I need to file ITR for getting money from mother

No, you do not need to file an ITR or pay taxes on the ₹11,000. Money received from a mother is a tax-free gift, and since you have no other income, you fall well below the mandatory filing limit.

Is there any necessary to report this transaction ?

While you don't need to report it now, it is always a good practice to keep a simple record (like the bank statement showing the transfer) just in case the tax department ever asks about the source of funds in your wallet. For such a small amount, a formal "Gift Deed" is usually unnecessary.

Thanks for clearing my confusion, I really appreciate your help.
