F&O Turnover Under ₹1 Crore with a Loss: Is Tax Audit Mandatory for Partnership Firms & LLPs?
If you search the internet for “F&O tax audit rules for losses,” you will find a graveyard of conflicting advice.
The most common—and dangerously incorrect—claim you will read is this: “If your F&O turnover is less than ₹1 crore and your profit is less than 6%, or you have a loss, a tax audit is mandatory.”
This generic advice completely ignores the 5-year lock-in rule under Section 44AD(4). Worse, it confuses the tax audit rules for Individuals (who have a basic exemption limit of ₹2.5L/₹3L/₹7L) with the rules for Partnership Firms, which are taxed at a flat 30% and have a basic exemption limit of ₹NIL.
If you are running a Partnership Firm or a Limited Liability Partnership (LLP) that trades in Futures & Options (F&O), incurs a net loss, and has a turnover of less than ₹1 crore, the rules apply very differently to you.
In this highly targeted guide, we will deconstruct the exact interplay between Section 44AB, Section 44AD, and the Income Tax Act’s “basic exemption limit” clause to prove exactly why a loss-making partnership firm with turnover under ₹1 crore is exempt from tax audit.
Step 1: Calculating F&O Turnover (The 2026 Standard)
Before discussing audit applicability, we must calculate turnover correctly. F&O trading is classified as non-speculative business income under Section 43(5) proviso (d) of the Income Tax Act, provided the trades are carried out on a recognized stock exchange.
To calculate turnover, we strictly follow the ICAI 8th Edition Guidance Note on Tax Audit u/s 44AB (issued 19 August 2022).
The Formula:
F&O Turnover = Sum of Absolute Profits + Sum of Absolute Losses
Note: The older practice of adding the premium received on options writing to the turnover is obsolete. The ICAI clarified in 2022 that premium is already accounted for in the net profit/loss of the trade and should NOT be added separately.
Because F&O trading is 100% digital (no cash receipts or payments), the standard ₹1 crore tax audit threshold under Section 44AB(a) is legally elevated to ₹10 crore.
Therefore, if your F&O turnover is under ₹1 crore, you are well below the primary ₹10 crore threshold. But does a loss trigger an audit through a backdoor? That depends on your business structure.
Step 2: The LLP vs. Partnership Firm Divide
The biggest mistake traders make is assuming LLPs and traditional Partnership Firms are treated identically under the Income Tax Act. When it comes to presumptive taxation, they are worlds apart.
The LLP Scenario
Under Section 44AD(6) of the Income Tax Act, Limited Liability Partnerships (LLPs) are explicitly excluded from opting into the presumptive taxation scheme.
Because an LLP cannot opt into Section 44AD, it can never “opt out” or break the 5-year lock-in rule. Therefore, the dreaded Section 44AB(e)—which forces an audit on businesses that declare low profits/losses after breaking the 44AD lock-in—does not apply to LLPs.
For an LLP, tax audit applicability is governed strictly by Section 44AB(a):
- Is turnover > ₹10 crore (since F&O is 100% digital)?
- If No -> No Tax Audit.
It does not matter if the LLP has a profit of 1%, a profit of 20%, or a massive loss. If turnover is under ₹10 crore, an LLP does not require a tax audit for F&O.
The Traditional Partnership Firm Scenario
Traditional Partnership Firms (registered under the Indian Partnership Act, 1932) are eligible for Section 44AD. This is where the tax logic gets highly technical, and where most tax portals get it wrong.
Step 3: The Partnership Firm Loophole (Section 44AD(4) & 44AB(e))
Let’s assume your traditional Partnership Firm has an F&O turnover of ₹80 Lakhs and a net loss of ₹5 Lakhs.
Because the firm is eligible for Section 44AD, we must look at its history to determine if Section 44AB(e) triggers an audit.
Scenario A: The Firm has NEVER opted for Section 44AD in the past 5 years
If the firm has never declared F&O income under the presumptive 6% scheme in any of the preceding 5 years, it is not bound by the 5-year lock-in.
- Turnover is < ₹10 crore.
- Lock-in is not broken.
- Result: No Tax Audit.
Scenario B: The Firm OPTED for Section 44AD previously, but now has a loss
This is the scenario that confuses everyone.
Suppose the firm declared 6% presumptive profit last year. This year, it incurred a loss. By declaring a loss, the firm is opting out of Section 44AD, triggering the 5-year lock-in penalty under Section 44AD(4).
When Section 44AD(4) is triggered, the Income Tax Act points you to Section 44AB(e) to check if an audit is mandatory.
Let’s read the exact legal condition of Section 44AB(e):
A person must get their accounts audited if they fall under Section 44AD(4) AND their total income exceeds the maximum amount which is not chargeable to income-tax.
This is the “Basic Exemption Limit” clause.
For an Individual, the basic exemption limit is ₹3,00,000 (under the new regime). If an individual has a loss, their income is negative, which is less than ₹3,00,000. Hence, no audit.
But what about a Partnership Firm? A Partnership Firm is taxed at a flat rate of 30% from the very first rupee. It has a basic exemption limit of ₹NIL (Zero).
Many tax professionals mistakenly argue: “Since a firm has no exemption limit, ANY income or loss triggers an audit if 44AD is broken.”
This is mathematically and legally false. The law requires the total income to EXCEED the maximum amount not chargeable to tax (which is ₹0).
If a Partnership Firm has a net loss of ₹5,00,000, its total income is -₹5,00,000. Does -₹5,00,000 exceed ₹0? No.
Because the firm’s total income (a loss) does not exceed the basic exemption limit (₹0), the second mandatory condition of Section 44AB(e) fails.
Result: Even if a Partnership Firm breaks the 44AD lock-in, a net loss means NO TAX AUDIT is required.
Worked Example: “Alpha Traders” Partnership Firm
Let’s look at a real-world calculation for Assessment Year 2026-27 (Financial Year 2025-26).
- Entity: Alpha Traders (Traditional Partnership Firm)
- F&O Absolute Profit: ₹30,00,000
- F&O Absolute Loss: ₹55,00,000
- Total F&O Turnover (ICAI Method): ₹85,00,000
- Net Result: Net Loss of ₹25,00,000
- Past History: Opted for 44AD in FY 2024-25.
Audit Applicability Test:
- Section 44AB(a): Turnover is ₹85 Lakhs. This is below the ₹10 Crore digital limit. (No audit under this section).
- Section 44AD(4): The firm is declaring a loss, breaking the 5-year lock-in from FY 2024-25. This triggers Section 44AB(e).
- Section 44AB(e) Test: Does the total income exceed the basic exemption limit?
- Total Income = -₹25,00,000
- Basic Exemption Limit for Firm = ₹0
- Since -₹25,00,000 is NOT greater than ₹0, the condition fails.
- Final Verdict: No Tax Audit is required.
What About Books of Account? (Section 44AA)
Just because you are exempt from a tax audit does not mean you are exempt from accounting.
Under Section 44AA of the Income Tax Act, a business must maintain books of account if:
- Income from business exceeds ₹1.2 lakh in any of the 3 preceding years, OR
- Total sales/turnover exceeds ₹10 lakh in any of the 3 preceding years.
Since your F&O turnover is likely above ₹10 lakh (even if under ₹1 crore), your Partnership Firm or LLP must maintain proper books of account (ledger, journal, bank statements, contract notes). You simply don’t need a Chartered Accountant to audit them via Form 3CB-3CD.
Filing the ITR: Forms, Due Dates, and Loss Carry Forward
To claim and carry forward your F&O loss, you must file your Income Tax Return correctly and on time.
1. Which ITR Form?
Partnership Firms and LLPs engaging in F&O trading must file ITR-5. (Note: Individuals file ITR-3, but firms file ITR-5).
2. Setting Off and Carrying Forward Losses
- Same Year Set-Off (Section 71): Your F&O loss (non-speculative business loss) can be set off against any other income in the same financial year, except salary income. (Since a firm doesn’t earn salary, it can set this off against interest income, rental income, or capital gains).
- Carry Forward (Section 72): If the loss cannot be fully set off in the current year, it can be carried forward for 8 Assessment Years. In future years, it can only be set off against business income.
3. Due Dates for AY 2026-27
To carry forward a loss, you must file your ITR before the due date. A late return forfeits your right to carry forward business losses.
- Non-Audit Due Date: As per the amendments in the Finance Act 2026, the due date for non-audit ITRs has been extended to 31 August 2026 (previously 31 July).
- Audit Due Date (If applicable): Tax Audit Report (Form 3CB-3CD) is due by 30 September 2026, and the corresponding ITR is due by 31 October 2026.
The Penalty for Missing a Tax Audit (Section 271B)
If you miscalculate your turnover or incorrectly assume you don’t need an audit when you actually do (e.g., your turnover crossed ₹10 crore), the tax department will levy a penalty under Section 271B.
The penalty is:
- 0.5% of total sales/turnover, OR
- ₹1,50,000 (Whichever is LOWER).
2026 Update Note: The Finance Act 2026 converted this from a “penalty” to a “fee” status to reduce litigation, but the financial impact (the amount) remains unchanged.
Frequently Asked Questions (FAQs)
1. Is tax audit mandatory for a partnership firm with F&O loss and turnover below ₹1 crore? No. Even if the firm breaks the Section 44AD 5-year lock-in, Section 44AB(e) only mandates an audit if total income exceeds the basic exemption limit. Since a loss is negative income, it does not exceed the firm’s ₹NIL exemption limit.
2. Can an LLP opt for presumptive taxation under Section 44AD for F&O trading? No. Section 44AD explicitly excludes Limited Liability Partnerships (LLPs). Their tax audit applicability is governed strictly by the ₹1 crore / ₹10 crore turnover limits under Section 44AB(a).
3. How is F&O turnover calculated for tax audit purposes in AY 2026-27? As per the ICAI 8th Edition Guidance Note (August 2022), F&O turnover is the sum of absolute profits plus the sum of absolute losses for each trade. Premium received on options writing is not added separately.
4. What is the due date to file ITR for a non-audit partnership firm for AY 2026-27? For AY 2026-27, the due date for filing a non-audit ITR (ITR-5 for firms) has been extended to 31 August 2026, as per the amendments in the Finance Act 2026.
5. Do I need to maintain books of account if my firm has an F&O loss and no tax audit is required? Yes. Under Section 44AA, if your F&O turnover exceeded ₹10 lakh or business income exceeded ₹1.2 lakh in any of the preceding three years, you must maintain books of account, even if an audit is not mandatory.
