📜 What the law says — Section 503, Income-tax Act 2025
503. (1) After a finding of total partition has been recorded by the Assessing Officer
under section 315 for any Hindu family, notices under this Act in respect of the
income of the Hindu family shall be served on the person, who was its last manager,
or, if such person is dead, then on all adults who were members of the Hindu family
immediately before the partition.

for the income of such firm or association may be served on any person, who was
a partner (not being a minor) or member of the association, immediately before

Service of notice in case of discontinued business.
In plain language
What Section 503 actually deals with
Section 503 of the Income-tax Act, 2025 is a procedural machinery provision in the "General" / miscellaneous part of the Act. It answers a very practical question: once a Hindu Undivided Family (HUF) has broken up, or a firm or association of persons (AOP) has been dissolved, who does the Income-tax Department serve its notices on? A dissolved firm or a partitioned HUF no longer exists as a functioning entity, so a notice cannot simply be handed to "the firm" or "the family". Section 503 fixes the correct legal recipient so that assessment, reassessment and recovery of the entity's past tax cannot be defeated merely because the entity has ceased to exist.
This section is the re-enacted successor to Section 283 of the Income-tax Act, 1961. The wording is carried over almost verbatim; the only real change is the updated cross-reference to the new Act's partition-finding provision.
The two situations it covers
- Disrupted (partitioned) Hindu family — Section 503(1): After the Assessing Officer records a finding of total partition of an HUF under Section 315 of the 2025 Act (the successor to Section 171 of the 1961 Act), any notice relating to the past income of the HUF must be served on the person who was its last Karta (manager). If that person has died, the notice is served on all the adult members who belonged to the family immediately before the partition.
- Dissolved firm or AOP — Section 503(2): Where a firm or other association of persons is dissolved, a notice relating to the income of that firm/AOP may be served on any person who was a partner (not being a minor) or a member immediately before dissolution. Note the important limitation: it can never be served on a minor partner.
Who it applies to
- Former Kartas and adult members of an HUF that has undergone total partition recognised by the Department.
- Adult (non-minor) partners of a dissolved partnership firm or LLP treated as a firm.
- Members of a dissolved AOP or Body of Individuals (BOI).
- Legal heirs step in only through the death route in sub-section (1); otherwise this section is about the surviving natural persons behind the entity.
Key conditions and limits
- A formal order is a pre-condition for HUF cases. Sub-section (1) only bites after the AO has recorded a total-partition finding under Section 315. Without that order, the HUF is still deemed to continue and is served in the normal way.
- It covers total partition only — a partial partition does not disrupt the family for this purpose (partial partition of an HUF is generally not recognised for tax).
- For firms/AOPs, service on any one adult partner/member is valid service on the whole dissolved entity.
- Minors are excluded as valid recipients in the firm/AOP case.
- There is no monetary threshold, rate or fee — this is a pure procedure section.
How it interacts with related sections
- Section 315 (assessment after partition of an HUF) supplies the trigger; 503 supplies the service mechanism that follows.
- Section 504 (successor to s.284) handles service in the case of a discontinued business, a close cousin situation.
- Sections 501–502 deal with the general mode and authentication of notices; 503 is a special-case carve-out to those general rules.
- Liability that gets crystallised through a 503 notice is recovered through the recovery machinery and the joint-and-several liability rules for firms/AOPs and for members of a partitioned HUF.
Practical implications
- Winding up does not wipe out tax exposure. Ex-partners and ex-Kartas remain reachable for the entity's pre-dissolution/pre-partition tax years.
- If you were the last Karta, keep records even after partition — a valid notice can still land on you.
- When drafting a partnership dissolution deed, address who will handle post-dissolution tax notices and how any liability is shared, because the Department can pick any adult partner.
- A notice served correctly under Section 503 is legally valid; an assessee generally cannot escape assessment by arguing "the firm/HUF no longer exists".
💡 Example
Worked example 1 — Dissolved firm: "Sharma & Associates" was a firm of three partners: Anil, Bela and Chetan. The firm is dissolved on 30 June 2026. In December 2026 the Department finds unassessed income of ₹18,00,000 for the year the firm was still operating, creating a tax demand of about ₹5,40,000. Under Section 503(2), the AO can validly serve the reassessment notice on any one of the three adult ex-partners — say Anil alone. That single service is good service against the dissolved firm; Anil cannot argue the notice is invalid because the firm no longer exists, though the eventual liability is shared among the partners.
Worked example 2 — Partitioned HUF: The "Verma HUF" was managed by Karta Ramesh Verma with four adult members. The AO records a total partition under Section 315 effective 1 April 2026. Later, income of ₹9,00,000 relating to an earlier year (tax roughly ₹1,80,000) surfaces. Under Section 503(1), the notice must go to Ramesh (the last Karta). If Ramesh had already passed away, the notice would instead be served on all four adult members who were part of the family just before partition.
Relatable story: Two brothers, Kunal and Manav, ran a small trading firm and dissolved it after a falling-out, each assuming "the firm is closed, so tax is closed." Eighteen months later a notice for an old year arrived at Kunal's home. He panicked, thinking it was a mistake since the firm was gone. His CA explained Section 503: because he was an adult partner immediately before dissolution, the notice was perfectly valid — dissolving the firm never dissolved its tax history. They responded on time and settled the matter, but it was a costly reminder that "closing the business" is not the same as "closing the tax file."
| Situation | Trigger / pre-condition | On whom notice is served | Key limit |
|---|
| Total partition of HUF (primary recipient) | AO records total-partition finding under Section 315 | Person who was the last Karta / manager | Total partition only; partial partition not covered |
| Total partition of HUF (Karta has died) | Last Karta is deceased | All adult members of the family immediately before partition | Only adults; minors not served |
| Dissolved firm / LLP-as-firm | Firm dissolved | Any one adult partner immediately before dissolution | Cannot be served on a minor partner |
| Dissolved AOP / BOI | Association dissolved | Any member immediately before dissolution | Service on one member is valid for all |
| 1961 Act equivalent | — | Same rule under Section 283 | Cross-ref was to old Section 171 (now Section 315) |

Frequently asked questions
What is Section 503 of the Income-tax Act, 2025 about?
It sets out who the Income-tax Department must serve notices on when a Hindu Undivided Family has undergone total partition or when a firm/association has been dissolved. It ensures notices remain valid even though the entity no longer functions.
Which section of the old Income-tax Act, 1961 does it replace?
It re-enacts Section 283 of the 1961 Act almost word for word. The main change is that the cross-reference for HUF partition is now to Section 315 (instead of the old Section 171).
After my firm is dissolved, can the Department still send it a notice?
Yes. Under Section 503(2), a notice for the firm's pre-dissolution income can be served on any one adult (non-minor) partner who was a partner immediately before dissolution, and that is valid service on the dissolved firm.
Who receives the notice when an HUF is partitioned?
The notice goes to the person who was the last Karta (manager). If the last Karta has died, it is served on all the adult members who were in the family just before the partition.
Can a notice under this section be served on a minor?
No. In the dissolved firm/AOP case, the notice can only be served on a partner or member who is not a minor.
Does Section 503 create any new tax or apply to partial partition of an HUF?
No. It is purely a procedural provision with no tax, rate or threshold. And it applies only to total partition recorded under Section 315; a partial partition is not covered.
I was one of several partners — am I personally liable if served under Section 503?
Being served makes the notice valid against the dissolved firm and puts you on record. The underlying tax is dealt with under the firm/AOP liability rules, so it is wise to respond and coordinate with the other ex-partners rather than ignore it.
