Rule 136 of Income explained: this guide covers what it means, who it applies to, the step-by-step process, documents required, fees, due dates and penalties in India — so you can stay compliant with confidence and avoid costly mistakes.
Rule 136 of the Income-tax Rules, 2026 provides that the option under sections 199(3), 200(5), 201(2), 202(4), 203(5) and 204(2) "shall be in the return of income to be furnished under section 263(1) for such tax year". The separate election forms of the 1962 Rules — 10-IC, 10-ID, 10-IE, 10-IEA and their siblings — have no counterpart.
The whole rule, in one sentence
Rule 136 is one of the shortest operative rules in the 2026 rulebook, and one of the most consequential for ordinary filing:
"The option to be exercised or withdrawn under the provisions specified in column B of the following Table, by a person specified in column C thereof, for any tax year shall be in the return of income to be furnished under section 263(1) for such tax year."
It replaces rules 21AD to 21AHA of the Income-tax Rules, 1962 — the family of rules that each prescribed a separate election form with its own filing deadline.
The Table — who elects under which section
| Sl. No. | Section | Person |
|---|---|---|
| 1 | 199(3) | Manufacturing domestic company |
| 2 | 200(5) | Domestic company |
| 3 | 201(2) | New manufacturing domestic company |
| 4 | 202(4) | Individual or Hindu undivided family, or an association of persons (other than a co-operative society) or a body of individuals, whether incorporated or not, or an artificial juridical person |
| 5 | 203(5) | Resident co-operative society |
| 6 | 204(2) | New manufacturing co-operative society |
Why this is a real change, not a renumbering
Under the 1962 Rules the election lived in a separate form with its own due date, and a large volume of disputes turned on nothing more than a form filed late or not filed at all while the return itself claimed the concessional rate. Rule 136 removes that failure mode entirely: there is no separate form to miss. The election is made by the return, so a return filed within section 263(1) carries the election with it.
What the change does not do is relax the timing discipline. The option "shall be in the return of income to be furnished under section 263(1)" — that is, the return furnished within the section 263(1) time limit. The deadline has not disappeared; it has merged into the return's own deadline.
Exercise and withdrawal are treated identically
Both the heading of rule 136 and its operative words say "exercised or withdrawn". A taxpayer stepping out of a regime does it the same way as stepping in — through the return for that tax year. There is no separate withdrawal intimation.
The substantive limits on how often a person may switch are not in rule 136. Those sit in the sections themselves — sections 199 to 204 — and must be read there. Rule 136 governs only the manner of the election.
How the 1962 architecture maps across
| Point | Rules 21AD to 21AHA (1962) | Rule 136 (2026) |
|---|---|---|
| Number of election rules | Several, one per regime | One rule with a six-row Table |
| Election instrument | A separate prescribed form | The return of income |
| Separate due date | Yes, generally before the return | No — the section 263(1) return deadline |
| Withdrawal | Separate treatment | Same instrument as the exercise |
| Electronic filing mechanics | Per form | Return filing mechanics, rule 164 |
Worked example
A domestic manufacturing company wants the section 201 regime for tax year 2026-27, and an individual client wants to move out of the section 202 default regime for the same year.
- The company makes the election in its return of income for tax year 2026-27, furnished within the section 263(1) time limit. No separate election form is filed.
- The individual's exit is likewise made in the return for that year — the same instrument, under Sl. No. 4 of the rule 136 Table.
- Neither election has its own deadline. Both stand or fall with the return's own timeliness under section 263(1).
Compliance checklist
- Remove separate election forms from the tax-year 2026-27 filing checklist; there is no rule 136 form.
- Make sure the election field in the return is completed deliberately, not left at its default — the return is now the only place the choice is recorded.
- Confirm the return is furnished within section 263(1); the election travels with it.
- Identify the correct row of the Table — sections 199, 200, 201, 203 and 204 are entity-specific, and 202 covers the non-corporate, non-co-operative persons.
- Read the section, not rule 136, for how many times a person may switch.
- Retire references to rules 21AD to 21AHA and to the old election forms.
Common mistakes
- Looking for a form that rule 136 does not prescribe, and delaying the return while trying to file one.
- Assuming the election has become deadline-free. It is tied to the section 263(1) return.
- Filing a separate withdrawal intimation. Withdrawal is in the return too.
- Applying the co-operative society rows to an association of persons. Section 202(4) expressly excludes a co-operative society from the AOP limb.
- Reading the switching restrictions out of rule 136. They are in sections 199 to 204.
