Tax Audit When You Have a Loss: Interest Income, Depreciation and the Cases Nobody Talks About

A loss does not switch off tax audit, and a profit does not switch it on. What decides audit is the nature of your receipts, the head of income they fall under, and whether you have ever opted for presumptive taxation.

Every audit season we meet two kinds of clients. One says, "My business made a loss, so I don't need an audit." The other says, "I earned ₹1 crore of interest, so I must need one." Both can be wrong.

Most articles stop at the turnover limit and the 5% cash test. This one looks at the cases those articles skip:

• A company or firm with nil or negligible turnover but bank interest of ₹1 crore or more

• A business where depreciation alone turns a profit into a loss

• A small business that once filed under the presumptive scheme and now has a loss

• How the new Income-tax Act, 2025 changes the picture from Tax Year 2026-27

For FY 2025-26 (AY 2026-27), the 1961 Act still applies. The section numbers below follow that Act unless stated otherwise.

The basic rule: audit follows receipts, not profit

Section 44AB has five triggers. Two look only at receipts. The other three look at profit, and all three apply only to people who use presumptive taxation.

• 44AB(a), business turnover: above ₹1 crore, or above ₹10 crore where cash receipts and cash payments are each within 5%. Profit or loss is irrelevant.

• 44AB(b), professional receipts: above ₹50 lakh. Profit or loss is irrelevant.

• 44AB(c), presumptive cases under 44AE, 44BB or 44BBB: triggered when lower profit is claimed.

• 44AB(d), professionals under 44ADA: triggered when less than 50% is claimed and income exceeds the exemption limit.

• 44AB(e), businesses in the 44AD(4) lock-in: triggered when income exceeds the exemption limit.

Two consequences follow, and most of this article builds on them.

First, under clause (a), a business with ₹1.2 crore turnover and a ₹15 lakh loss needs an audit. The loss is irrelevant.

Second, clause (a) counts only "sales, turnover or gross receipts" in business. A receipt that is not business income does not count towards the limit, however large it is. That is the key to the interest-income question.

Scenario 1: Nil turnover, but ₹1 crore of bank interest

Whether ₹1 crore of interest triggers an audit depends on one question: is that interest business income, or income from other sources? The amount alone decides nothing.

Case A: Surplus funds parked in fixed deposits

Take a company that sold its factory, or a firm whose trading has wound down. It keeps ₹15 crore in FDs and earns ₹1.1 crore of interest. Sales are nil.

Interest earned by investing surplus funds is ordinarily taxed as "income from other sources". The Supreme Court took this view in Tuticorin Alkali Chemicals & Fertilizers Ltd v. CIT (1997). It is not a receipt "in business", so it does not count towards the ₹1 crore limit in 44AB(a).

Result: no tax audit under 44AB, even with ₹1.1 crore of interest. A company still needs its statutory audit under the Companies Act. A partnership firm or individual needs neither, provided nothing else triggers one.

Two cautions apply:

• Be consistent. If the books and the return present the interest as business income, the department can hold you to that. Classify it once, correctly, and keep it that way.

• Interest on FDs kept as margin money for a bank guarantee or letter of credit is different. That interest is tied to the business, and courts have often treated it as business income. In that case, the safer course is to include it when testing the limit.

Case B: Lending is the business

For a money-lender, finance firm, NBFC or credit co-operative society, interest is the turnover. The ICAI's Expert Advisory Committee has said that only the gross interest counts. Loan principal given and repaid is excluded (ICAI EAC opinion).

Two details catch lenders out:

• Gross, not net. A lender who earns ₹1.1 crore of interest and pays ₹1.05 crore on borrowings has a turnover of ₹1.1 crore, not ₹5 lakh. If expenses leave a loss, audit is still required.

• The 5% cash test counts every cash rupee. The higher ₹10 crore limit applies only if cash receipts and cash payments are each within 5% of the total. Those totals include loan repayments collected in cash, not just interest. A lender who collects EMIs in cash will usually fail the test, so the ₹1 crore limit applies.

Case C: Big interest income plus a small, loss-making business

This is the case most people miss. Mr. Desai earns ₹1.2 crore of FD interest. He also runs a small shop with ₹40 lakh of sales. In FY 2023-24 he declared 8% profit under section 44AD. In FY 2025-26 the shop made a loss of ₹3 lakh, and he wants to report that loss.

Interest is not turnover, so 44AB(a) does not apply. But he opted into 44AD and is now declaring less than the presumptive rate within five years. That brings him under the 44AD(4) lock-in. Clause 44AB(e) then asks a second question: does his total income exceed the basic exemption limit? After setting the ₹3 lakh loss off against interest, his total income is still about ₹1.17 crore.

Result: tax audit required, on a business with ₹40 lakh of sales and a loss. The large interest income is what pushes him over the exemption limit, even though interest never counts as turnover.

Scenario 2: The loss comes only from depreciation

A depreciation-driven loss never changes the turnover test. It matters only where the audit trigger depends on total income: the presumptive-scheme cases under 44AB(e).

This scenario is common in Belagavi among lodge and hotel owners, transporters, small manufacturers and anyone who has just bought machinery. The business earns a cash profit, but depreciation on new assets turns it into a tax loss.

If turnover is above the audit limit

Audit is required. Depreciation does not reduce turnover, and 44AB(a) ignores profit. A ₹1.5 crore manufacturer with a ₹6 lakh depreciation loss and more than 5% cash dealings needs an audit, full stop.

If turnover is below the limit

The answer turns on your presumptive-scheme history:

• Never opted for 44AD (or opted more than five years ago): no tax audit under the 1961 Act, even with a loss. You must still maintain books under section 44AA once turnover crosses ₹25 lakh or income crosses ₹2.5 lakh.

• Opted for 44AD within the last five years: you are in the lock-in. Audit is required only if your total income, after the depreciation loss is set off, exceeds the basic exemption limit.

That second test is where depreciation helps. Suppose a lodge owner's profit before depreciation is ₹7 lakh, depreciation is ₹9 lakh, and he has no other income. His total income is nil, below the exemption limit, so no audit is needed despite the lock-in. Add ₹6 lakh of rent or interest from elsewhere, and his total income becomes ₹4 lakh. Under the old regime that crosses ₹2.5 lakh, and audit is required.

Three points that are easy to get wrong

1. You cannot skip depreciation to avoid the loss. Since AY 2002-03, depreciation is deemed to have been allowed whether or not you claim it (Explanation 5 to section 32(1)). Your asset's written-down value falls either way.

2. "Exemption limit" does not mean the rebate limit. For FY 2025-26 the new-regime basic exemption is ₹4 lakh. The section 87A rebate makes income up to ₹12 lakh tax-free, but it does not raise the exemption limit for audit purposes. For a partnership firm the exemption limit is nil, so any positive income counts.

3. A loss made purely of depreciation is worth protecting. Unabsorbed depreciation under section 32(2) carries forward indefinitely. Section 80 bars carry-forward of business losses when the return is late, but it does not list unabsorbed depreciation. So even if you miss the due date, the depreciation portion survives.

The real choice for small businesses

An eligible business with turnover up to ₹2 crore (₹3 crore if cash receipts are within 5%) can still declare 6% or 8% under section 44AD. That avoids the audit, but you pay tax on a profit you did not make, and the depreciation is treated as already used. The alternative is to declare the true loss, get audited where the lock-in applies, and carry the depreciation forward. Run the numbers both ways before deciding.

The presumptive-scheme trap: when a loss does trigger audit

Under the 1961 Act, declaring less than 6% or 8% does not by itself require an audit. Since the Finance Act, 2016 (from AY 2017-18), a small business with turnover below the limit needs an audit only if both of these are true:

1. The lock-in applies. You declared profit under 44AD in some year, and in any of the next five years you declare less than the presumptive rate. That opt-out makes you ineligible for 44AD for the following five years.

2. Total income exceeds the basic exemption limit in that year.

A business that has never used 44AD can declare a thin profit or a loss with no audit, as long as its turnover stays under the limit. This point is well settled in professional commentary, yet clients still assume otherwise.

A loss usually fails the second test, so audit is not needed. But three kinds of other income can keep total income above the limit:

• Salary. A business loss cannot be set off against salary (section 71(2A)). A salaried person with a loss-making side business in the lock-in will usually need an audit.

• Interest, rent or capital gains. The loss is set off against these, but a large enough amount still leaves total income above the limit. Mr. Desai in Case C is the example.

• Speculative or other profits. These can sit alongside a non-speculative loss and keep income positive.

The practical takeaway is to check the last five years of returns before advising a client with a loss. Whether they once filed under 44AD decides the outcome.

Other audits that apply even when 44AB does not

Falling outside section 44AB does not mean no audit at all. Three entity types have their own rules.

• Charitable trusts and NPOs. A trust with only FD interest still needs its accounts audited if its income, before applying the exemption, exceeds the basic exemption limit. The report is Form 10B (income above ₹5 crore, foreign contribution, or income applied outside India) or Form 10BB (all others). A trust earning ₹6 lakh of FD interest and no other receipts needs this audit, though it has no "turnover".

• Companies. Every company needs a statutory audit under the Companies Act, whatever its turnover or loss. A dormant company with only FD interest does not need a separate tax audit report (Form 3CA/3CD) unless 44AB applies. Many such companies file one anyway, which is harmless but an avoidable cost.

• Co-operative societies. These are audited under state co-operative law. For a credit society, gross interest from members is its turnover for 44AB, as in Case B. Where 44AB applies, the tax audit report is given in Form 3CA, alongside the audit under co-operative law.

Quick check: FY 2025-26 (1961 Act)

1. Turnover ₹1.2 crore, cash above 5%, loss of ₹15 lakh: audit required. Section 44AB(a) looks only at turnover.

2. Turnover ₹3 crore, cash within 5%, loss: no audit, because this is within the ₹10 crore limit. The exception is a business in the 44AD lock-in with income above the exemption limit.

3. Nil sales, ₹1.1 crore interest on surplus FDs: no audit. The interest is income from other sources, not turnover.

4. Money-lender, ₹1.1 crore gross interest, net loss, EMIs collected in cash: audit required. Gross interest is turnover, and the cash test fails.

5. Turnover ₹40 lakh, depreciation loss, never used 44AD: no audit. Turnover is below the limit and there is no lock-in, though books must still be kept.

6. The same business, in the 44AD lock-in, no other income: no audit. Total income is below the exemption limit.

7. The same business, in the lock-in, ₹1.2 crore of FD interest: audit required under 44AB(e). Total income exceeds the exemption limit.

8. Salaried person, side-business loss, in the lock-in: audit usually required. A business loss cannot reduce salary income.

9. Trust with ₹6 lakh FD interest and nothing else: no 44AB audit, but the trust audit in Form 10BB applies.

What changes from Tax Year 2026-27

The Income-tax Act, 2025 keeps the audit thresholds but may have widened the presumptive-scheme trigger. Everything above applies to FY 2025-26. Income earned from 1 April 2026 falls under the new Act, and those audits will be done in 2027.

The renumbering is straightforward:

• Section 44AB (tax audit) becomes section 63.

• Sections 44AD, 44ADA and 44AE (presumptive taxation) become section 58.

• The 44AD(4) five-year lock-in becomes section 58(7).

• Forms 3CA, 3CB and 3CD are replaced by Form 26 from Tax Year 2026-27 (CBDT FAQ).

The turnover limits of ₹1 crore and ₹10 crore, the 5% cash test and the ₹50 lakh professional limit are unchanged. So is the analysis of interest income in Scenario 1.

The open question is the presumptive trigger. Section 63(1) has a separate entry for anyone carrying on a business covered by section 58 who claims profit below the deemed rate. Section 58(3) adds that such a person, if total income exceeds the exemption limit, must keep books and get audited "as required under section 63". Practitioners read this two ways:

• Wider reading: the old safe harbour is gone. Any eligible business that declares below 6% or 8% needs an audit, even one that never opted into the scheme (CA Sandesh Jain on TaxGuru).

• Narrower reading: "as required under section 63" keeps the turnover limits intact, so nothing has changed in substance (CA Lalit Munoyat on TaxGuru).

For loss cases, this matters most where other income keeps total income above the exemption limit. Under the wider reading, a small business with a depreciation loss and ₹1 crore of interest would need an audit from Tax Year 2026-27, even without any 44AD history. A genuine loss with no other income should stay outside the audit net under either reading, because total income does not cross the exemption limit.

Until the CBDT clarifies or a court decides, businesses expecting a loss this year should keep proper books from April 2026. If the wider reading prevails, an audit will then be possible without reconstructing the year.

If you got it wrong, and what to do now

Missing a required audit costs money. Wrongly assuming you need one also costs money.

The penalty under section 271B is 0.5% of turnover or ₹1.5 lakh, whichever is lower. A reasonable-cause defence is available under section 273B. A return filed without a required audit report can also be treated as defective, which delays refunds and loss carry-forwards.

For FY 2025-26, the CBDT has extended the tax audit report deadline to 21 October 2026 and the return deadline for audit cases to 21 November 2026 (King Stubb & Kasiva summary). If you have a loss, large interest income or a depreciation-heavy year, check before 21 October which side of the line you are on.

Before deciding, have these ready:

• Turnover and gross receipts, with interest classified as business income or other sources

• Cash receipts and cash payments as a share of the totals, including loan repayments

• Profit before and after depreciation

• Returns for the last five years, to see whether you ever filed under 44AD

• Other income: salary, rent, interest, capital gains
