Gifts: Cash gifts from a member to an HUF are generally tax-free for the HUF, but be aware of "clubbing of income" (Section 64(2)) if the gift involves income-generating assets.
Interest: Interest income earned by an individual on a loan given to their HUF is taxable for the individual. Only the distribution of the HUF's own income to its members is typically exempt under Section 10(2).
