A practitioner's guide to claiming legitimate expenditure against derivative profits while navigating section 37(1), 40(a)(ia), 40A(3) and 43B of the Income-tax Act, 1961
When a Futures and Options (F&O) trader walks into our office at the end of the financial year, the first question is rarely about how much profit was made -- it is about how much of that profit can legitimately be cushioned by expenses. The answer is governed by clause (d) of section 43(5) of the Income-tax Act, 1961, which treats trading in derivatives carried out on a recognised stock exchange as non-speculative business. The consequence flows in a straight line: F&O profit is taxed under the head Profits and Gains of Business or Profession, and the entire toolkit of business deductions in sections 28 to 44 of the Income-tax Act, 1961 (and the corresponding sections of the Income-tax Act, 2025 from Tax Year 2026-27 onwards) becomes available to the trader. The discipline lies in knowing where section 37(1) lets you in, and where sections 40, 40A and 43B push you back out.
This article is a structured walk-through of the expense ledger of a typical F&O trader -- from the brokerage note to the depreciation chart -- separating what the assessing officer should accept from what will be disallowed at the first scrutiny. Every figure quoted reflects the position after the Finance Act, 2024 (No. 2 of 2024) and the Finance Act, 2025 amendments.
1. Why F&O is Business Income, Not Capital Gains
Clause (d) of sub-section (5) of section 43 of the Income-tax Act, 1961 carves out derivative trading -- futures and options on shares, indices, currency and commodities transacted through a recognised stock exchange -- from the definition of speculative transaction. The consequence is that profit or loss from F&O is non-speculative business income, and the trader is treated as a person carrying on business. Three practical implications follow.
# | Implication | Effect on the Trader |
|---|---|---|
1 | Head of Income | Profits and Gains of Business or Profession -- not Capital Gains. Therefore concessional rates of 12.5% Long-Term Capital Gains tax or 20% Short-Term Capital Gains tax do not apply. The slab rate or section 115BAC rate is the rate. |
2 | Expense Deductibility | All sections 28 to 44 of the Income-tax Act, 1961 are available -- in particular section 37(1) which permits any expenditure laid out wholly and exclusively for the purposes of business. |
3 | Loss Set-off Flexibility | F&O loss is non-speculative business loss. It can be set off against any head of income except Salary in the same year, and carried forward for eight assessment years for set-off against business income. |
Once the trader is firmly inside the Profits and Gains of Business or Profession head, the next question becomes purely architectural: which expenses pass through section 37(1) without being intercepted by the disallowance provisions.
2. The Section 37(1) Gateway -- The General Rule
Section 37(1) of the Income-tax Act, 1961 is the residual provision. Any expenditure -- not being capital expenditure, not being personal expenditure, not being expenditure described in sections 30 to 36, and not being incurred for any purpose which is an offence or prohibited by law -- if laid out or expended wholly and exclusively for the purposes of the business, is allowed. Five filters must be cleared simultaneously.
Filter | Test | Common F&O Trip-Hazard |
|---|---|---|
Wholly and exclusively for business | Direct nexus with the trading activity | Family vacation passed off as broker meeting |
Not personal expenditure | No personal consumption element | Home internet bill claimed in full instead of proportionate share |
Not capital expenditure | Does not bring an enduring benefit | Cost of laptop debited in full instead of as depreciation |
Not covered elsewhere (sections 30 to 36) | Specific provisions take precedence | Interest on borrowed capital wrongly debited under section 37 instead of section 36(1)(iii) |
Not prohibited by law | Includes Explanation 1 fines, penalties, freebies | Penalty paid to Securities and Exchange Board of India for delayed disclosure |
Why each filter matters An expense that fails any one filter is disallowed in entirety. The Assessing Officer needs to find only one weakness. The trader's defence is documentation -- bills, bank statements, agreements, and a clear demonstration that the expense was incurred for the trading activity and nothing else. |
3. Direct Trading Costs -- All Allowable
These are the costs that appear on every contract note and exchange statement. Each one is a charge that the trader cannot avoid in order to participate in the market, and each is therefore a textbook example of expenditure laid out wholly and exclusively for the purposes of the business. Collectively these line items are typically the largest category of F&O expenses.
Expense Head | Statutory Position | Practitioner Note |
|---|---|---|
Brokerage paid to the stock broker | Allowable under section 37(1) as a direct trading cost | Pick the figure from the consolidated annual broker statement, not from individual contract notes. |
Securities Transaction Tax (STT) | Allowable as a business expense from Assessment Year 2009-10 onwards (the rebate route under the erstwhile section 88E was withdrawn). STT on the sale of futures rose from 0.0125% to 0.02% and STT on the sale of options rose from 0.0625% to 0.1% with effect from 1 October 2024. | Do not attempt to claim a section 88E rebate -- that section is no longer applicable. Claim STT only as a business expense. |
Goods and Services Tax (GST) on brokerage and exchange charges | Allowable as a business expense, since the trader is not registered under the Goods and Services Tax law for F&O activity (securities are not goods or services) and therefore cannot claim input tax credit | If the trader has unrelated GST registration for other business, the input tax credit position must be examined separately. |
Securities and Exchange Board of India turnover charges | Allowable | Visible as a separate line on the contract note. |
Stock exchange transaction charges (National Stock Exchange / Bombay Stock Exchange) | Allowable | Slab rates differ for cash equity, currency derivatives, and equity derivatives -- claim the actual amount paid. |
Stamp duty on contract notes | Allowable | From 1 July 2020, uniform stamp duty applies under the Indian Stamp Act, 1899 amendments -- 0.002% on futures and 0.003% on options, on the buyer side. |
Demat account annual maintenance and depository participant charges | Allowable | Attribute proportionately if the same demat account is used for long-term investing as well. |
Bank transaction charges and payment gateway fees on funding the trading account | Allowable | Reconcile against the bank statement. |
4. Indirect and Overhead Expenses -- Allowable Subject to Conditions
These are the costs of running the trading desk -- the room, the equipment, the staff, the data feed and the professional advisors. They are allowable, but each one carries a procedural condition that, if missed, becomes the ground for a disallowance.
Expense Head | Statutory Position | Compliance Trigger |
|---|---|---|
Internet, broadband and mobile data charges | Allowable, but the personal portion must be excluded | Maintain a reasonable basis of apportionment -- typically 60% to 80% business depending on usage pattern. |
Trading software, terminal, charting and analytics subscriptions (Bloomberg Terminal, Sensibull, Streak, Opstra, Quantsapp, TradingView, Reuters Eikon) | Allowable as revenue expenditure if paid annually or monthly | If paid as a one-time perpetual licence, treat as intangible asset and depreciate at 25%. |
Subscription to financial newspapers, journals and research services | Allowable | The Economic Times, Mint, Bloomberg Quint, MoneyControl Pro, ValuePickr, etc. |
Salary, bonus and contractual payments to research assistants, dealers and back-office staff | Allowable under section 37(1), but Tax Deducted at Source under section 192 of the Income-tax Act, 1961 must be deducted and deposited; otherwise 30% of the expense is disallowed under sub-clause (ia) of clause (a) of section 40 | Run a payroll -- even a one-person payroll. Issue Form 16. Deposit Tax Deducted at Source by the seventh of the next month. |
Rent of office premises used for trading | Allowable; if monthly rent exceeds rupees fifty thousand, Tax Deducted at Source under section 194-IB applies (for individuals not under tax audit) or under section 194-I (for those under tax audit) | Failure to deduct Tax Deducted at Source attracts the 30% disallowance under sub-clause (ia) of clause (a) of section 40. |
Electricity, water and society maintenance charges (proportionate to office usage) | Allowable | If working from home, claim only the business portion based on a reasoned methodology -- area used, hours used, separate meter, etc. |
Audit fees, Chartered Accountant fees, legal and professional fees | Allowable; Tax Deducted at Source under section 194J at 10% applies if aggregate annual payment to a single payee exceeds rupees thirty thousand | Without the Tax Deducted at Source, 30% of the fee is disallowed. |
Depreciation on computer, laptop, printer, scanner, uninterruptible power supply | Allowable at 40% under Block of Assets -- Computers (the rate continues under the Income-tax Act, 2025) | Capitalise the full purchase invoice including Goods and Services Tax (since input tax credit is not available). |
Depreciation on office furniture | Allowable at 10% | Maintain a fixed asset register; the assessing officer routinely asks for it. |
Depreciation on vehicle (only if used for business) | Allowable at 15%; if a luxury car, examine reasonableness under sub-section (2) of section 38 | Personal use portion must be disallowed -- typically 20% to 25%. |
Interest on loan taken for trading capital | Allowable under sub-clause (iii) of clause (1) of section 36, provided the loan is for business and the lender is genuine | Maintain loan agreement, bank statements and confirm payment of Tax Deducted at Source under section 194A if the lender is not a bank. |
Travel and conveyance for broker meetings, trading conferences, exchange events | Allowable | Maintain trip-wise vouchers; airfare and hotel bills; agenda of the conference. |
Books, courses and training programmes on derivatives, options strategies, risk management | Allowable as it sharpens the existing business skill (not new profession) | Personal Master of Business Administration tuition is not allowable -- that is a capital expenditure for acquiring a new qualification. |
Apportionment example A trader uses a single home internet connection for personal entertainment and for trading. Annual cost: rupees twelve thousand. Approximate business usage: 70%. Allowable expense in the F&O profit and loss account: rupees eight thousand four hundred. The remaining rupees three thousand six hundred is treated as personal drawings. The same logic applies to mobile phone bills, electricity, and the rent of a room used both as a bedroom and as a trading desk. |
5. Expenses That Are Disallowed Outright
These are the items the F&O trader must keep firmly outside the profit and loss account. Some are blocked by section 37(1) itself, others by the specific disallowance provisions in sections 40, 40A and 43B of the Income-tax Act, 1961.
Disallowed Expense | Governing Provision | Why It Is Disallowed |
|---|---|---|
Personal expenses -- groceries, family travel, school fees, medical bills (other than employer-employee medical reimbursement) | Section 37(1) | Not wholly and exclusively for business. |
Capital expenditure -- purchase price of laptop, furniture, office building, intangible asset | Section 37(1) | Only depreciation is allowable, not the full cost. |
Cash payment exceeding rupees ten thousand to a single person on a single day (rupees thirty-five thousand for transport contractors) | Sub-section (3) of section 40A | Entire payment is disallowed -- not just the excess over rupees ten thousand. |
Salary, rent, professional fees, interest, commission paid without deducting Tax Deducted at Source (or after deduction, without depositing) | Sub-clause (ia) of clause (a) of section 40 | 30% of the expense is disallowed in the year of default; allowed back in the year Tax Deducted at Source is finally paid. |
Goods and Services Tax, Provident Fund, Employee State Insurance, professional tax not paid before the due date for filing the return of income | Section 43B | Allowed only on actual payment basis; if unpaid by the return filing due date, deduction is deferred to the year of payment. |
Penalties, fines, late fees imposed for violation of any law -- Securities and Exchange Board of India penalty, exchange penalty, late filing fee under section 234F, interest under section 234A / 234B / 234C | Explanation 1 to section 37(1) and specific sections | Penalty for infraction of law is not deductible; tax-related interest and fees are explicitly non-deductible. |
Income tax paid on F&O profit | Sub-clause (ii) of clause (a) of section 40 | Income tax is an application of profit, not a charge against profit. |
Donations to charitable institutions | Section 37(1) | Allowable only as a deduction under section 80G from Gross Total Income, not as a business expense. |
Payments to relatives or specified persons in excess of fair market value | Sub-section (2) of section 40A | Excess portion over reasonable value is disallowed. |
Speculative loss (such as intra-day equity loss) set off against F&O profit | Sub-section (1) of section 73 | Speculative loss can be set off only against speculative profit; F&O is non-speculative and cannot absorb a speculative loss. |
Personal life insurance premium, medical insurance premium for self and family | Section 37(1) | Allowable as deduction under sections 80C / 80D from Gross Total Income, not as business expense. |
Wealth tax, gift tax, estate duty | Sub-clause (iia) of clause (a) of section 40 | Specifically disallowed. |
The Tax Deducted at Source trap The single most frequent disallowance our office sees in F&O scrutiny notices is the section 40(a)(ia) disallowance -- 30% of an otherwise legitimate rent, salary or professional fee, knocked off because Tax Deducted at Source was either not deducted or was deducted but not paid in time. The entire profit and loss can flip from healthy to thin on this one mistake. Set up a Tax Deducted at Source register from day one of trading. |
6. Worked Example -- Computing Net F&O Income
Mr. Rajesh, a full-time options trader from Pitampura, Delhi, has the following figures for Tax Year 2026-27. He trades through a single discount broker and works from a dedicated room in his apartment. He has no other business income.
Particulars | Amount (rupees) | Treatment |
|---|---|---|
Gross profit from F&O trading (broker statement) | 32,50,000 | Net of brokerage credited; will be re-grossed. |
Brokerage as per consolidated statement | 1,80,000 | Allowable -- direct trading cost |
Securities Transaction Tax | 2,40,000 | Allowable -- business expense post Finance Act, 2008 amendments |
Goods and Services Tax on brokerage | 32,400 | Allowable |
Stock exchange and Securities and Exchange Board of India charges | 18,000 | Allowable |
Stamp duty | 9,500 | Allowable |
Bloomberg Terminal subscription | 3,60,000 | Allowable -- annual subscription |
Internet and mobile (70% business) | 11,200 | Allowable -- 70% of rupees sixteen thousand |
Electricity (30% business portion) | 9,000 | Allowable -- proportionate |
Salary to research assistant | 6,00,000 | Allowable -- but Tax Deducted at Source under section 192 must be deducted |
Audit fee to Chartered Accountant | 75,000 | Allowable -- after deducting Tax Deducted at Source under section 194J |
Depreciation on laptop and trading rig (40%) | 48,000 | Allowable -- block of assets method |
Cash payment of rupees twenty-two thousand to a freelance coder | 0 | Disallowed under sub-section (3) of section 40A |
Donation to a temple trust | 0 | Disallowed as business expense; claim under section 80G separately |
Penalty paid to broker for margin shortfall | 0 | Disallowed under Explanation 1 to section 37(1) |
Net taxable F&O business income Re-gross the F&O profit by adding back the brokerage already netted off, then deduct the allowable expenses listed above. On the figures shown, allowable expenses aggregate to approximately rupees fifteen lakh seventy thousand (excluding the disallowed items). Net business income chargeable under Profits and Gains of Business or Profession works out to roughly rupees eighteen lakh sixty thousand, on which Mr. Rajesh will pay tax at his slab rate -- under the new tax regime of section 115BAC, the effective tax for Tax Year 2026-27 with full standard deduction logic will be in the region of rupees one lakh ninety thousand to rupees two lakh, depending on cess and surcharge. |
7. Books of Account, Tax Audit and Turnover
Section 44AA of the Income-tax Act, 1961 makes maintenance of books of account mandatory if business income exceeds rupees two lakh fifty thousand or turnover exceeds rupees twenty-five lakh in any of the three immediately preceding previous years. Almost every serious F&O trader crosses this threshold. Section 44AB then layers on a compulsory tax audit if turnover exceeds rupees one crore -- raised to rupees ten crore where 95% or more of receipts and payments are through banking channels (which is the normal case for F&O).
Compliance | Threshold | Practical Note |
|---|---|---|
Maintain books of account under section 44AA | Income above rupees two lakh fifty thousand or turnover above rupees twenty-five lakh in any of the three preceding years | Cash book, ledger, journal, broker reconciliation, fixed asset register |
Tax audit under section 44AB | Turnover above rupees one crore (rupees ten crore for digital trading) | Audit report in Form 3CD; due date 30 September; return filing 31 October |
Turnover for F&O | Absolute value of profit + absolute value of loss + premium received on options written (per Guidance Note of the Institute of Chartered Accountants of India) | Do not use the notional contract value; that overstates turnover dramatically |
Carry forward of F&O loss | Eight assessment years | Return must be filed within the due date under sub-section (1) of section 139; otherwise carry-forward is lost |
8. Practitioner Pitfalls and Defensive Documentation
- Reconcile the broker's profit and loss statement with the trader's own Demat-bank flow at the end of every quarter -- mismatches discovered in March cost time and money.
- Treat every annual subscription to a trading platform as revenue expenditure; treat every perpetual licence as a depreciable intangible at 25%.
- Issue a Tax Deducted at Source certificate (Form 16 / Form 16A) for every payee -- staff, landlord, Chartered Accountant -- before 15 June following the financial year.
- If working from home, designate a specific room or square footage for trading and apportion electricity, internet and rent on a written, reasoned basis -- do not pull a percentage out of the air.
- Never net off losses against profits in the broker statement before reaching turnover. Turnover for section 44AB must be computed on the gross-absolute basis spelt out by the Institute of Chartered Accountants of India.
- Keep the contract notes, ledger, bank statements, demat statements, broker reconciliation, software invoices, asset purchase invoices and Tax Deducted at Source challans for at least eight years.
- Securities Transaction Tax, Goods and Services Tax on brokerage, exchange charges and stamp duty are all expenses, not capital costs -- claim them in the year of payment.
9. Key Takeaways
- F&O is non-speculative business income under sub-clause (d) of sub-section (5) of section 43 of the Income-tax Act, 1961 -- the full menu of business deductions in sections 28 to 44 is available.
- Direct trading costs -- brokerage, Securities Transaction Tax, exchange charges, Goods and Services Tax on brokerage, stamp duty, Securities and Exchange Board of India charges -- are all allowable in entirety.
- Indirect overheads -- internet, software, salary, rent, professional fees, depreciation -- are allowable, but each carries a Tax Deducted at Source or apportionment condition that, if missed, triggers a 30% or 100% disallowance.
- Watch out for the four big disallowance provisions: Explanation 1 to section 37(1) (penalties and prohibited expenditure), sub-section (3) of section 40A (cash payments above rupees ten thousand), sub-clause (ia) of clause (a) of section 40 (Tax Deducted at Source defaults), and section 43B (statutory dues unpaid by return filing date).
- Maintain books of account under section 44AA; conduct tax audit under section 44AB if turnover exceeds rupees one crore (rupees ten crore for digital trading).
- File the return of income within the due date to preserve the eight-year carry-forward of F&O loss against future business income.
