Sections 344 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.
Sections 344, 345 and 346 of the Income-tax Act, 2025 deal with a registered non-profit organisation that holds a business undertaking or carries out a commercial activity. Section 344 gives the Assessing Officer the power to determine the income of the undertaking. Section 345 and section 346 say when commercial activity is allowed. This article reads them as per the Income-tax Act, 2025 (30 of 2025) as amended by the Finance Act, 2026.
A registered non-profit organisation may carry out a commercial activity only on conditions. Under section 345, the activity must be incidental to the attainment of the objectives and separate books of account must be kept. An organisation that advances "any other object of general public utility" is governed by section 346 instead: the activity must be part of actually advancing that object, aggregate receipts must not exceed 20% of total receipts of the tax year, and separate books must be kept. Breach of these conditions has consequences under sections 351 and 353.
Where these sections sit
These sections form part 3, "Commercial activities by registered non-profit organisation", of Part B of Chapter XVII (sections 332 to 355). The Chapter is summarised in the Chapter XVII guide. The opening registration step is covered in our post on section 332. Later amendments, rules and notifications should be checked.
If your organisation sells services or goods alongside its charitable work, these three sections tell you what you must keep in place. Our page on 12A, 80G and CSR registration describes how we help non-profit organisations with their compliance.
Meaning of "commercial activity"
The definition is in section 355(e) and applies "for the purposes of this Part". A commercial activity is any activity in the nature of trade, commerce or business, or any activity of rendering any service in relation to any trade, commerce or business, for a cess or fee or any other consideration. The definition adds that this is irrespective of the nature of use or application, or retention, of the income from the activity. So the label of the activity does not matter, and neither does what the organisation does with the money afterwards. Our article on section 355 covers the other definitions: definitions for registered non-profit organisations.
Section 344: business undertaking held as property
Section 344 reads as a single rule. Where the property held by a registered non-profit organisation includes a business undertaking, and a claim is made that the income of that undertaking is eligible for benefits under this Part, the Assessing Officer has the power to determine the income of the business undertaking as per the provisions of this Act.
Three points follow from the words:
- The section applies only where the organisation's property includes a business undertaking. It does not cover an incidental activity that is not an undertaking.
- It is triggered by a claim that the income of the undertaking is eligible for benefits under this Part (sections 332 to 355).
- The Assessing Officer determines the income "as per the provisions of this Act", that is, the provisions of the whole Act, not only of this Part.
The section does not itself say how the determination is made, what notice is needed or what time limit applies. The text is silent on these; they must be read from the rest of the Act.
Section 345: the general restriction
Section 345 applies to a registered non-profit organisation other than one mentioned in section 346. Such an organisation shall not carry out any commercial activity unless:
| Clause | Condition |
|---|---|
| (a) | The commercial activity is incidental to the attainment of the objectives of the registered non-profit organisation |
| (b) | Separate books of account are maintained for such activities |
Both clauses are joined by "and", so both must be satisfied. The Act does not define "incidental" beyond these words; whether an activity is incidental to the objectives is a question of fact for each organisation.
Section 346: organisations advancing any other object of general public utility
Section 346 is addressed to a registered non-profit organisation carrying out advancement of any other object of general public utility. It says that no such organisation shall carry out any commercial activity unless all three of the following hold:
| Clause | Condition |
|---|---|
| (a) | The commercial activity is undertaken in the course of actual carrying out of advancement of any object of the general public utility |
| (b) | The aggregate receipts from such commercial activity or activities do not exceed 20% of the total receipts of the registered non-profit organisation of the relevant tax year |
| (c) | Separate books of account are maintained by the organisation for such activities |
The limit in clause (b) is measured against total receipts of the registered non-profit organisation for the relevant tax year. The text does not define "total receipts" in this section. Receipts from the commercial activity or activities are counted together ("aggregate").
The consequences of getting it wrong
These sections only state the restriction. The consequences are in the next sections of the Part:
- Section 351(1)(b) lists as a specified violation the carrying out of commercial activity in contravention of section 345. The consequences of a specified violation, including cancellation of registration, are in section 351(2) and (3). See our post on specified violations.
- Section 353(1)(d) covers an organisation advancing any other object of general public utility that carries out commercial activity in contravention of section 346. Its regular income, reduced by the expenditure described in section 353(3), becomes taxable regular income chargeable to tax as per section 334.
So the two groups of organisations are treated differently: a breach of section 345 is a specified violation, while a breach of section 346 is dealt with in section 353. The Finance Act, 2026 changed section 351(1)(b) by omitting the reference to section 346 (footnote 66 of the copy consulted).
Worked example
Rangoli Education Society (an invented name) is a registered non-profit organisation whose objects are educational. It sells printed question papers to other schools for a fee. Under section 345 the society may do this only if the activity is incidental to its educational objectives and it keeps separate books of account for the sale. If the society keeps its sales in its general ledger and does not maintain separate books, condition (b) of section 345 is not met.
Now take Green Valley Welfare Trust (invented), which advances an "other object of general public utility" and has total receipts of Rs. 50,00,000 in a tax year. It runs a small training programme, which is a commercial activity undertaken in the course of advancing its object, and keeps separate books. Under section 346(b), aggregate receipts from commercial activities must not exceed 20% of Rs. 50,00,000, that is, Rs. 10,00,000. If the training programme brings in Rs. 8,00,000, the limit is respected. If the trust adds a second commercial activity and the aggregate becomes Rs. 11,00,000, the limit is exceeded and the consequence in section 353(1)(d) is attracted for that tax year.
