Hi @sanjana
Wherein any individual receives money in excess of 50,000 in any Financial Year without any consideration, such money will be taxed as Income from Other Sources in the hands of the recipient. However, this rule does not apply to money received from any relative, the definition of which includes your parents. Therefore, the amount credited by your father by way of a gift into your NRO account shall not be taxable.
Yes, the money needs to be sent to an NRO account. The gift from your parents cannot be credited to your NRE account. There is no such limit on gifts from relatives. Any gift given by them to you would be tax-free for both parties so far as India tax incidence is concerned.
Hope this helps
