As per Guidence note on Tax Audit under Section 44AB of the IT Act 1961 by ICAI,
10.10 AS apply in respect of commercial, industrial or business activities of an enterprise. In the case of charitable or religious organisations, AS will not apply if all activities of such organisations are not of commercial, industrial or business nature (e.g. an activity of collecting donations and giving them to flood affected people). In other words, exclusion of an entity from the applicability of the AS would be permissible only if no part of the activity of such entity is commercial, industrial or business in nature.
10.19 Financial statements prepared on a basis other than accrual
With regard to the fundamental accounting assumption of accrual, the Council has made a specific announcement that in respect of (a) Sole proprietary concerns/individuals, (b) Partnership firms, (c) Societies registered under the Societies Registration Act, (d) Trusts, (e) Hindu undivided families and (f) Association of persons, the auditor should examine whether the financial statements have been prepared on accrual basis. In case where the statute governing the enterprise requires the preparation and presentation of financial statements on accrual basis but the financial statements have not been so prepared, the auditor should qualify his report.
On the other hand where there is no statutory requirement for preparation and presentation of financial statements on accrual basis, and the financial statements have been prepared on a basis other than ‘accrual’, the auditor should describe in his audit report, the basis of accounting followed, without necessarily making it a subject matter of a qualification.
