Under Section 56(2) of the Income Tax Act, any sum of money received from a relative (which includes children) is completely exempt from tax, regardless of the amount.
Physical presence is not mandatory for gifting movable property like money (unlike land or houses).
For money transfers, a formal registered "Gift Deed" is often not strictly required by the Income Tax Department if you have a Gift Letter. Your daughter can draft a letter on her letterhead or plain paper in Kenya, sign it, and send you the scanned copy (and the original by post).
It must state her name, address, relationship to you, the amount transferred, the date, the bank transaction ID, and a clear statement that the money is being given out of "love and affection" and is irrevocable.
You must have the document ready before you file your Income Tax Return (ITR) for the financial year in which the gift was received. This ensures you have the proof ready if the tax officer asks about the "source of funds."
