Form 10BB Audit Report & Disclosure

Form 10BB Audit Report & Disclosure

Form 10BB is the statutory audit report that a charitable institution, university, hospital, or approved fund must file before it can claim income tax exemption under section 10(23C) of the Income-tax Act, 1961. For FY 2026-27 / AY 2027-28, Form 10BB must be filed electronically on the Income Tax e-filing portal by 30 September 2027 — one clear month before the ITR-7 audit-case deadline of 31 October 2027. Miss that date and the institution forfeits its exemption for the entire year, with surplus income taxed at the maximum marginal rate. This guide walks you through every filing requirement, disclosure, and pitfall in the order you need to act on them.

What Is Form 10BB and Who Must File It

Form 10BB is mandated under Rule 17B of the Income-tax Rules, 1962, read with section 10(23C) of the Income-tax Act, 1961. It was last comprehensively overhauled by CBDT via Notification No. 7/2023 dated 21 February 2023, which drew a sharp line between the two principal trust audit reports: Form 10B (for institutions registered under section 12A / 12AB claiming exemption under section 11) and Form 10BB (for institutions approved under section 10(23C) claiming exemption under that section).

You must file Form 10BB if your institution falls under any of these sub-clauses:

• Section 10(23C)(iv): A fund or institution of national importance, established for charitable purposes, and notified by the Central Government.
• Section 10(23C)(v): A trust or institution existing wholly for public religious purposes or public religious and charitable purposes, notified by the Central Government.
• Section 10(23C)(vi): Any university or other educational institution existing solely for educational purposes (not for profit), approved by the Principal Commissioner of Income Tax (PCIT).
• Section 10(23C)(via): Any hospital or other medical institution existing solely for philanthropic purposes, approved by the PCIT.

Institutions under (iiiab) (substantially government-funded universities) and (iiiad) (smaller educational institutions with aggregate annual receipts below Rs. 5 crore, as notified) are also entitled to exemption under section 10(23C), but their audit and filing obligations differ — confirm the applicable rules with your CA based on current CBDT notifications.

The audit trigger for (vi) and (via) entities: if total receipts in the previous year exceed Rs. 5 crore (as notified), Form 10BB is mandatory. Below that threshold, audit remains best practice from a governance standpoint.

What the Section 10(23C) Approval Actually Means for Your Filing

Before you can file Form 10BB, your institution must hold a valid, current approval from the PCIT. Since the Finance Act 2022, approvals under section 10(23C)(vi) and (via) are granted for five years and must be renewed before expiry. A lapsed approval creates a gap period during which exemption can be denied in full.

Your approval letter states the applicable sub-clause. Verify this before your CA populates Form 10BB — a mismatch between the clause claimed in ITR-7 and the clause in the approval letter is a standalone ground for rejection during scrutiny.

Since the Finance Act 2022, an institution cannot simultaneously claim exemption under both section 11 (through 12AB registration) and section 10(23C). If your hospital or university holds both credentials, you must elect one regime for AY 2027-28 and be consistent throughout the year. The election is made implicitly by which form you file — Form 10B signals section 11, Form 10BB signals section 10(23C).

Key Disclosures in Form 10BB: What the Auditor Actually Certifies

Form 10BB is a structured disclosure document. The Chartered Accountant signs it with a Digital Signature Certificate (DSC) after verifying each section against the institution's books. Here are the areas that matter most in practice.

The 85% Application of Income Test

The central computation in Form 10BB is whether at least 85% of income — not 85% of gross receipts — was applied to the institution's stated objects in India during the year. The remaining up to 15% can be accumulated or set aside without any formal notice or approval.

What counts as "applied":

• Salaries and stipends of teachers, doctors, nurses, and other staff engaged in the institution's objects.
• Procurement of educational materials, medicines, diagnostic equipment, and consumables used in patient care.
• Repairs and maintenance of buildings and assets used exclusively for the institution's objects.
• Scholarships paid to students.
• Capital expenditure on assets used for the institution's objects — a new laboratory block or an MRI machine qualifies as application in the year of acquisition, not spread over the asset's depreciation life.

What does NOT count:

• Expenditure on assets that are even partly used for the personal benefit of trustees or specified persons.
• Administrative overheads that are disproportionate to the institution's scale.
• Payments to related parties at above-market rates.

Corpus Donations: The Most Scrutinised Line Item

A corpus donation is a contribution made with a specific written direction from the donor — signed and dated at the time of receipt — that the amount shall form part of the corpus of the institution. This direction cannot be given retroactively.

Corpus donations are not treated as income and are therefore excluded from the 85% application computation. However, they must be invested or deposited in instruments specified under section 11(5), which include:

• Government securities
• Fixed deposits with scheduled commercial banks
• Post office deposits
• Units of UTI
• Bonds notified by the Central Government for this purpose

Voluntary contributions received without a written corpus direction are treated as income and must pass through the 85% filter.

Maintain a signed donor-declaration register. Every corpus receipt, however small, needs a corresponding written direction. A large unrestricted donation retrospectively labelled as "corpus" will not survive scrutiny.

Related-Party Transactions Under Section 13(3)

Section 13(3) defines "specified persons" — trustees, founder-members, their relatives, and any company or AOP in which any of them holds a substantial interest. Every transaction between the institution and a specified person must be:

• Fully disclosed in Form 10BB with the name of the specified person, nature of the transaction, and amount.
• Conducted at arm's length — market rate for goods, services, or properties.
• Approved by the governing board, with the interested trustee abstaining.

Even a below-market rent charged to a trustee's company, or a construction contract awarded to a trustee's relative at a premium, triggers section 13 and can result in the exemption being denied for the entire year — not just the transaction amount.

Foreign Contributions (FCRA Disclosures)

If your institution is registered under the Foreign Contribution (Regulation) Act, 2010, Form 10BB requires disclosure of all foreign contributions received during the year. These must:

• Have been received only in the designated FCRA bank account (State Bank of India, as specified under FCRA 2020 amendment rules).
• Be recorded in a separate FCRA receipt-and-payment account.
• Reconcile exactly with your Form FC-4 annual return filed on the FCRA online portal.

The Income Tax Department and the Ministry of Home Affairs increasingly cross-reference Form 10BB figures against FC-4 data. A rupee difference between the two triggers queries.

How to File Form 10BB: Step-by-Step Process on the Income Tax Portal

The filing is entirely electronic at unknown node. Here is the sequence for AY 2027-28:

1. Log in using the institution's PAN credentials.
2. Navigate to e-File → Income Tax Forms → File Income Tax Forms.
3. Search for Form 10BB and select Assessment Year 2027-28.
4. Part A — Entity details: Name, PAN, address, date of PCIT approval, and the applicable sub-clause of section 10(23C).
5. Part B — Income details: Gross receipts, corpus donations, non-corpus voluntary contributions, and income from investments (interest, rent, capital gains).
6. Part C — Application of income: Object-wise expenditure breakdown, capital expenditure on objects, details of any prior-year application brought forward.
7. Part D — Corpus and investment details: List each corpus investment with instrument type, name of institution/bank, amount, and confirmation of section 11(5) compliance.
8. Part E — Related-party transactions: Names of all specified persons under section 13(3), nature of each transaction, amount, and arm's-length confirmation.
9. Part F — FCRA details (if applicable): Amount of foreign contributions, donor country, purpose, and FCRA registration number.
10. Attach audited financial statements: balance sheet, income and expenditure account, receipts and payments account, and notes to accounts — as a single PDF, ideally under 5 MB.
11. The CA signs using their registered DSC. The institution's authorised signatory (Managing Trustee or Secretary) also signs with their DSC.
12. Submit and download the Acknowledgment Receipt (ARN) — retain it as proof of timely filing.

Portal tips: DSC registration mismatches (CA's DSC linked to a different e-filing profile) are the single biggest cause of last-minute delays. Test your DSC on the portal well before September. Save drafts frequently — the portal times out after 30 minutes of inactivity.

Statutory Deadlines and the Real Cost of Missing Them

For FY 2026-27 / AY 2027-28, the standard compliance calendar is:

Important caveat: CBDT issues extension circulars from time to time — monitor unknown node and the e-filing portal. Do not plan around an extension; plan for the standard date and treat any extension as a buffer.

If Form 10BB is filed after the deadline, the institution forfeits exemption under section 10(23C) for that entire assessment year. The surplus is brought to tax. Under section 164, the applicable rate for a charitable institution whose exemption is denied is the Maximum Marginal Rate (MMR) — 30% plus applicable surcharge plus 4% health and education cess.

There is no partial relief — you cannot claim exemption for the months during which you were compliant. The exemption is binary for the year.

Worked Example: What a Missed Deadline Actually Costs

Institution: Rameshwari Educational Foundation — an educational society approved under section 10(23C)(vi).

FY 2026-27 financials:

The Foundation's CA completed audit fieldwork in mid-October 2027. Form 10BB was filed on 15 October 2027 — 15 days after the 30 September 2027 deadline.

Tax consequence (AY 2027-28):

A 15-day delay cost the Foundation Rs. 6,66,000. At a scholarship value of Rs. 50,000 per student, that is 13 scholarships lost — far more than the incremental cost of scheduling the audit a month earlier.

Section 10(23C) vs Section 12A: Choosing the Right Exemption Regime

If you run an educational institution or hospital, you may hold both a section 12AB registration (entitling you to claim under section 11) and a section 10(23C) approval. Since the Finance Act 2022, you must elect one regime per year. Here is how the two compare:

Practical rule of thumb: Multi-purpose trusts that carry out both religious and educational activities generally retain section 12AB registration because section 10(23C) does not accommodate religious objects well. Pure educational institutions and hospitals that receive PCIT-supervised grants tend to stay within section 10(23C) because it is cleaner for their governance structure. Once you choose a regime for a year, switching mid-year is not possible. Switching across years is permitted but triggers consistency questions during scrutiny — document the reason for any change in regime in the trust's board resolution.

Common Mistakes That Trigger Form 10BB Scrutiny

1. Corpus Without a Written Direction

Treating a large unrestricted donation as corpus purely to exclude it from the 85% computation. The written direction must pre-date or be contemporaneous with the receipt. Fix: Introduce a standard one-page donor declaration form at the point of collection and have it countersigned by the institution's treasurer.

2. Section 11(5) Investment Violations

Corpus funds parked in equity mutual funds, company fixed deposits, or chit funds — none of which appear in the section 11(5) prescribed list. Fix: Review investment compliance every quarter. When an FD matures, re-invest within 15 days in a compliant instrument.

3. Application Shortfall Without Formal Notice

The institution applied 76% of income and simply carried forward the 9% shortfall with no formal communication to the tax authority. Fix: If you anticipate a shortfall before 31 March, consult your CA immediately. A formal notice of intention to accumulate, submitted in the prescribed manner before the due date, protects the balance.

4. Capital Expenditure Not Linked to Objects

A vehicle purchased as a "school transport bus" but also used by a trustee for personal travel. The entire asset cost claimed as application was disallowed. Fix: Maintain a fixed asset register with user-mapping for each asset, supported by a board resolution confirming the asset is used exclusively for the institution's objects.

5. FCRA-ITR-Form 10BB Triangle Mismatch

Foreign contributions recorded as ordinary voluntary income in the income and expenditure account, with different figures appearing in Form FC-4. Fix: Maintain a separate FCRA receipt-and-payment account; reconcile it against FC-4 data quarterly before any of the three filings is submitted.

6. Late Engagement of the Chartered Accountant

Books handed over in late September for an audit that should have begun in June. A thorough audit of a Rs. 2-crore institution — including application-of-income tracing, section 11(5) investment verification, and related-party mapping — cannot be done in two weeks. Fix: Sign the audit engagement letter by end of May. Target completion of fieldwork by 31 August. Allow a minimum of two to three weeks for portal processing, DSC coordination, and review cycles.

7. Omitting Minor Related-Party Disclosures

Trustees underestimate what counts as a related-party transaction. Using the institution's printer for personal documents, hiring a trustee's relative as a contract gardener, or providing free meals to a trustee's family during an event — all of these are technically disclosable. Fix: Circulate a related-party declaration form to all trustees and senior staff at the beginning of each financial year and update it at least quarterly.

Key Takeaways

• Form 10BB is the mandatory audit report for section 10(23C)(iv), (v), (vi), and (via) entities — file it electronically on the Income Tax e-filing portal, signed by the CA and the authorised signatory using DSC.
• For FY 2026-27 / AY 2027-28, the standard filing deadline is 30 September 2027 — plan your audit to complete fieldwork by 31 August at the latest.
• A missed deadline forfeits the entire year's exemption — a modest surplus of Rs. 20 lakh results in a tax-and-interest bill of approximately Rs. 6,66,000 at the Maximum Marginal Rate.
• Corpus donations require a contemporaneous written direction from the donor and must be invested exclusively in section 11(5)-compliant instruments — equity mutual funds and company deposits do not qualify.
• The 85% application of income rule applies to income (not gross receipts). Capital expenditure on objects qualifies in full in the year of acquisition; expenditure benefiting trustees personally does not qualify at all.
• Related-party transactions under section 13(3) must be fully disclosed and arm's-length priced — even minor omissions can trigger denial of the full year's exemption.
• FCRA, ITR-7, and Form 10BB are actively cross-verified by the department — reconcile all three documents against each other before submitting any one of them.
