Common questions

FAQs.

Who needs to file Form 10B?
Every public charitable or religious trust / institution registered under Section 12A or 12AB of the Income-tax Act 1961 must obtain an audit report in Form 10B from a Chartered Accountant if its total income (before exemption under Sections 11 and 12) exceeds the basic exemption limit. Trusts registered under Section 10(23C) follow a similar requirement, with some institutions using Form 10BB.
What's the difference between Form 10B and Form 10BB?
Form 10B is the audit report for trusts/institutions registered under Section 12A or 12AB. Form 10BB is the audit report for institutions referred to in Section 10(23C) — specifically (iv), (v), (vi) and (via) — like educational and medical institutions wholly or substantially financed by the Government, or annual receipts up to ₹5 crore. Both forms cover similar disclosures; this generator follows the Form 10B structure which is the more common form.
When is the due date for filing Form 10B?
Form 10B must be filed at least one month before the due date for filing the trust's return of income under Section 139(1). For most trusts this means filing by 30 September of the assessment year if the return is due by 31 October. Failure to file Form 10B can result in loss of exemption under Sections 11 and 12.
What is the 85% income application rule referenced in the annexure?
Under Section 11(1), a trust must apply at least 85% of its income (derived from property held under trust) towards charitable or religious purposes in India during the previous year, to claim exemption. The remaining 15% can be accumulated without restrictions; amounts beyond 15% can be accumulated only by following Section 11(2) — filing Form 10 and investing in specified modes under Section 11(5).
Who are the "specified persons" under Section 13(3)?
Specified persons include the author/founder of the trust, persons who have contributed more than ₹50,000, any relative of the above, any concern in which any of the above has a substantial interest, and any trustee/manager of the trust. Section 13 disallows exemption if income/property is applied for the direct or indirect benefit of these persons — hence the detailed disclosures in Part II of the annexure.
Do I need to file UDIN with Form 10B?
Yes. The Chartered Accountant signing Form 10B must generate and quote a Unique Document Identification Number (UDIN) from the ICAI portal. The UDIN is required on the audit report itself and is verified by the Income-tax department portal at the time of filing.
