This discussion clarifies that a Hindu Undivided Family (HUF) cannot claim tax deductions for contributions made to the Karta's Public Provident Fund (PPF) account, as HUFs cannot open PPF accounts. However, HUFs can claim deductions under Section 80D for Mediclaim payments made for the Karta and his very senior citizen father, with a total deduction limit of £50,000. The father of the Karta is considered a member of the son's HUF for this purpose.
