This is the first of a three-part series on the Hindu Undivided Family. Part 2 covers what a family must do when the Karta dies. Part 3 covers how a deceased coparcener's share actually devolves.

What an HUF actually is

In twenty-five years of practice I have seen the HUF used brilliantly, and I have seen it neglected until a death in the family turns it into an expensive mess. The root cause is the same: families treat it as a tax device rather than what it legally is — a joint family that already exists, whether or not anyone files a return for it.

The Income-tax Act, 1961 nowhere defines "Hindu Undivided Family." It simply lists it in section 2(31)(ii) as a separate person, leaving the meaning to Hindu law. A joint family consists of all persons lineally descended from a common ancestor, together with their wives and unmarried daughters. It arises by operation of law, not by agreement. No deed creates it.

That single sentence disposes of the two questions I am asked most at the outset. No, you do not "form" an HUF by executing a deed — the deed and the corpus declaration merely record what already exists. And no, an HUF that has no property is not a fiction; it simply has nothing yet to be assessed on.

Members and coparceners — not the same thing

Distinguish these carefully — everything after a death turns on it. Every person in the family is a member. Only some are coparceners: those who take an interest in the joint property by birth and can demand partition. Under Mitakshara law, applicable across most of India, the coparcenary covers the holder of the property and three generations of lineal descendants.

Since the Hindu Succession (Amendment) Act, 2005, effective 9 September 2005, a daughter is a coparcener by birth on exactly the same footing as a son. The Supreme Court in Vineeta Sharma v. Rakesh Sharma (2020) settled that this right flows from birth and does not depend on the father being alive on the date of the amendment. A daughter therefore stays a coparcener in her father's HUF even after marriage, while becoming a member — not a coparcener — of her husband's HUF, as is a wife.

Hold on to that distinction. A member has rights of maintenance and residence and is counted when property is divided. A coparcener has an interest from the moment of birth and can walk into court and demand partition. Members cannot. In Part 3 of this series, this difference decides the entire outcome for a widowed daughter-in-law.

One regional caveat: in West Bengal and Assam the Dayabhaga school applies. Nobody acquires a right by birth, and the Karta holds as owner during his lifetime — which changes the succession outcome entirely.

Why the Income-tax Act cares

Because the HUF is a separate person, it gets its own PAN, files its own return, and enjoys its own basic exemption limit along with deductions under sections 80C, 80D and 80TTA. Rent, business profits, interest and capital gains from HUF-owned assets are assessed in its hands, not the Karta's. A family holding a let-out shop yielding ₹6 lakh a year can legitimately move that income out of a 30% individual slab.

The corpus has to come from somewhere defensible. Ancestral property, assets received on partition, a bequest under a will expressly in favour of the HUF, and gifts from members are all sound. Where families come unstuck is in assuming that anything transferred to the HUF gets taxed there.

The limits matter as much as the benefits. Section 64(2) claws back income where an individual converts self-acquired property into HUF property. The section 87A rebate and section 80U deduction are for individuals only. An HUF existing only on paper, without genuine corpus, invites disallowance.

Get these fundamentals right and the HUF is one of the few entirely legitimate income-splitting structures left in Indian tax law. Get them wrong, and every year of returns rests on a foundation the Assessing Officer can knock over in a single hearing.

Part 2, tomorrow: the Karta dies. Who becomes the new Karta, what has to be filed and amended across the bank, the demat account, GST and the income-tax portal — and what it costs a family to miss that year's return.
