NGO & Trust Audit - Form 10B / Form 10BB Filing
Once a registered trust, NGO, or Section 8 company's total income - before claiming exemption - crosses the basic exemption limit in a financial year, the Income Tax Act requires its accounts to be audited by a chartered accountant and the audit report filed before the income tax return. This audit is filed as Form 10B (larger or more complex entities) or Form 10BB (smaller entities below the prescribed income threshold). We assign a CA who understands charitable trust accounting - corpus donations, restricted grants, application of income - and get your audit report filed on time so your 12A/12AB exemption is not put at risk.

What is a Section 12A(1)(b) audit for NGOs and trusts?
Charitable trusts, registered societies, and Section 8 companies that hold valid registration under Section 12A or 12AB of the Income Tax Act are allowed to claim exemption on the income they apply towards their charitable or religious objects. Section 12A(1)(b) attaches a condition to that exemption: once the entity's total income, computed before claiming this exemption, exceeds the basic exemption limit in a financial year, its accounts must be audited by a chartered accountant and the audit report obtained in the prescribed form before the return of income is filed.
This is a different audit from a company's statutory audit under the Companies Act, and different again from a tax audit under Section 44AB that applies to businesses crossing turnover thresholds. The 12A(1)(b) audit looks specifically at how the trust or NGO applied its income towards its stated objects, whether it accumulated any income under Section 11(2), whether it made any prohibited investments, and whether any income was diverted for the benefit of trustees, founders, or related parties in breach of Section 13.
Depending on the entity's income level and complexity, the audit report is filed as Form 10B or Form 10BB on the income tax e-filing portal. Both are functionally the same audit under Section 12A(1)(b) - the form determines the level of reporting detail required, not whether the audit applies. 'NGO audit' and 'audit for charitable trust' are two common names for this same requirement, whether the entity is structured as a trust, a registered society, or a Section 8 company.
Form 10B vs Form 10BB: which applies to your NGO or trust?
Both forms report the same Section 12A(1)(b) audit - the difference is the entity's income level and the level of reporting detail required. Our CA team confirms which one applies before starting your audit.
Form 10B

Who needs an NGO or trust audit under Section 12A(1)(b)?
This audit is not optional bookkeeping - it is a statutory condition attached to your tax exemption.
- Your entity is a registered public charitable trust, a registered society, or a Section 8 company, holding valid registration under Section 12A or 12AB of the Income Tax Act
- Your entity's total income, computed before claiming exemption under Sections 11 and 12, has exceeded the basic exemption limit in the relevant financial year
- You claim exemption on income applied towards charitable or religious purposes and want that exemption to stand up to scrutiny
- You have accumulated part of your income under Section 11(2) for a specific project and need this reported and certified
- Your trust or NGO has business income incidental to its charitable objects under Section 11(4A) that needs to be reported alongside donation income
- You received a query, notice, or intimation from the Income Tax Department referencing a missing or defective audit report
- Entities with total income below the basic exemption limit before claiming exemption are not required to get this audit done, though maintaining audited accounts voluntarily is still good practice for donor and FCRA reporting

How the NGO/trust audit works
The audit is completed before your ITR-7 return is due - starting early avoids a last-minute scramble around the deadline.
Share your registration and financial documents
Send us your 12A/12AB certificate, trust deed or incorporation documents, and the year's books of accounts, bank statements, and donation register.
We confirm whether Form 10B or Form 10BB applies
Based on your total income before exemption and the complexity of your income sources, our CA team determines the correct form and threshold applicable for the year.
CA reviews books and verifies application of income
The assigned chartered accountant checks that income was applied towards charitable objects, accumulations under Section 11(2) were properly earmarked, investments comply with Section 11(5), and no income was diverted to trustees or related parties in breach of Section 13.
Draft financial statements and audit report prepared
We prepare the Balance Sheet, Income & Expenditure account, and the audit report in the applicable Form 10B or 10BB format, and share it with you for review before filing.
Audit report filed on the income tax e-filing portal
Once you confirm the figures, the CA digitally signs and files the audit report electronically, ahead of your ITR-7 filing deadline.
Audit report handed off for your ITR-7 filing
The filed audit report acknowledgement number is required when filing your ITR-7 return - we can handle that filing too under our separate Trust/NGO Tax Filing service.
This audit is a legal requirement once your income crosses the threshold, not a discretionary add-on - skipping it does not just risk a penalty, it puts your entire Section 11/12 exemption at risk for that year, meaning your income could be taxed at normal rates. If you are unsure whether your entity's income has crossed the threshold this year, ask us before assuming it doesn't apply.

Why getting the audit right matters
Protects your exemption
- A timely, correctly filed Form 10B or 10BB is what keeps your Section 11/12 exemption intact for the year - without it, the exemption can be denied even if your spending was entirely charitable
- A CA who understands corpus donations, restricted grants, and accumulation under Section 11(2) is less likely to leave a reporting gap that draws a query later
Builds donor and regulator trust
- Institutional donors, CSR funders, and grant-making foundations routinely ask for audited financials before releasing funds
- A clean audit trail supports your FCRA compliance and 80G donor certificates, if applicable
Keeps you filing-ready
- The audit report number is required to file your ITR-7 return - having it done early avoids a last-minute rush before the return deadline
- A consistent audit record year-on-year makes future 12A/12AB renewal and 80G renewal reviews smoother

Frequently asked questions
It is a mandatory audit of a registered trust, NGO, or Section 8 company's accounts by a chartered accountant, required once the entity's total income - before claiming exemption under Sections 11 and 12 - exceeds the basic exemption limit in a financial year. The audit report is filed as Form 10B or Form 10BB before the income tax return.
Yes. These are two common names for the same statutory requirement under Section 12A(1)(b) of the Income Tax Act. Whether your entity is structured as a trust, a registered society, or a Section 8 company, the same audit and filing obligation applies once your income crosses the threshold.
Both report the same 12A(1)(b) audit. Form 10B is generally used by larger or more complex trusts/NGOs - those with business income, foreign contributions, or higher income levels - and requires more detailed reporting. Form 10BB is used by smaller entities below the prescribed income threshold, with a comparatively simpler format.
No. The audit is only mandatory in a financial year where the entity's total income, computed before claiming exemption, exceeds the basic exemption limit. If your income stays below that limit, the audit is not compulsory, though maintaining audited accounts voluntarily is still useful for donor reporting.
Only a practising Chartered Accountant can conduct a Section 12A(1)(b) audit and sign Form 10B or Form 10BB - it cannot be self-certified by the trustees or done by an unregistered accountant.
No. A Section 8 company may separately be subject to a statutory audit under the Companies Act, 2013, in addition to this income-tax audit under Section 12A(1)(b). The two serve different purposes and are governed by different laws, though the same CA firm can often handle both.
The audit report (Form 10B or 10BB) must be furnished electronically before you file your ITR-7 income tax return for the year - the audit is a precondition to filing a valid return claiming exemption, not something done afterward.
Missing or delayed filing of the audit report can result in the Section 11/12 exemption being denied for that year, meaning the entity's income could be assessed and taxed at normal rates - a materially worse outcome than the audit's cost.
The CA verifies your books of accounts, confirms income was applied towards charitable or religious objects, checks that any accumulation under Section 11(2) was properly earmarked and invested, verifies investments comply with Section 11(5), and confirms no income or property was used to benefit trustees, founders, or related parties in breach of Section 13.
Only if the entity's total income before exemption crosses the basic exemption limit in that first year. A newly registered trust with modest income in year one may not need the audit yet, but should track income levels through the year to know when it becomes applicable.
The audit (Form 10B/10BB) certifies your accounts and application of income for the year. The income tax return (ITR-7) is the separate return you file afterward, using figures from the audited financials. We offer both as separate services, or bundled together - see our Trust/NGO Tax Filing service for the return itself.
Yes. Any entity holding valid registration under Section 12A or 12AB - whether structured as a trust, a registered society, or a Section 8 company - is subject to the same Section 12A(1)(b) audit requirement once its income crosses the threshold.
The audit becomes mandatory once total income, computed before claiming exemption under Sections 11 and 12, exceeds the basic exemption limit applicable for the year. The exact income band that separates Form 10B from Form 10BB is set by government notification and can be revised, so we confirm the current applicable figures at the time of your engagement.
We support the Section 12A(1)(b) income-tax audit for entities that also hold FCRA registration, including reconciling foreign contribution figures against your books. A separate FCRA-specific audit and annual return (Form FC-4) is a distinct filing, which we can quote for separately.
Yes - our Audit + ITR-7 Filing Bundle covers the applicable audit form and the subsequent ITR-7 return in one coordinated engagement, so both deadlines are tracked together and nothing is filed at the last minute.
If total income before exemption stays under the basic exemption limit for the financial year, the Section 12A(1)(b) audit is not mandatory. You would still typically file an ITR-7 return, but without the audit report requirement attached.
