What Traders Can Deduct (That Investors Cannot)

beginner6 min read

Business classification’s consolation prize: brokerage, data, internet, hardware, even STT — every trading cost trims taxable profit.

The one genuine perk of business-income classification: businesses deduct the costs of doing business. An investor’s STT quietly disappears; a trader’s STT is an expense line. Everything you spend wholly and exclusively to trade reduces the profit you pay slab tax on.

Direct trade costs — brokerage, exchange charges, STT, stamp duty, GST on brokerage: all deductible against business income.
Infrastructure — internet, market-data subscriptions, charting software, VPS, trading courses/books/research services.
Hardware — laptop/monitors via depreciation (40% WDV for computers); a fraction of rent/electricity if you trade from a dedicated space.
Advisory & compliance — CA fees, tax-filing platform charges, even interest on capital genuinely borrowed to trade.
The rule — wholly & exclusively for the business, with bills/records; proportionate claims for mixed-use (that 50%-personal internet line).

The mindset shift: run trading like the small business it legally is. A trader netting ₹6 lakh gross who diligently books ₹1.1 lakh of genuine costs (brokerage ₹40K, data + software ₹25K, internet share ₹10K, laptop depreciation ₹20K, CA ₹15K) pays slab tax on ₹4.9 lakh — at 30% that is ₹33,000 saved by bookkeeping. Investors get no such menu; if the taxman insists your P&L is a business, take the business’s privileges.

Test yourselfWhich of these can a salaried F&O trader deduct against trading profit: (a) STT, (b) TradingView subscription, (c) the metro pass to office?

(a) and (b) — both are wholly-and-exclusively trading costs (STT is deductible against BUSINESS income, unlike for investors). The metro pass serves the salary job, not the trading business. Keep invoices for everything claimed.

✓ You learnedBusiness income’s upside is the expense menu: trade costs (incl. STT), data, software, connectivity, depreciation and professional fees all reduce taxable trading profit. Keep bills, claim honestly and proportionately — for an active trader the bookkeeping habit is worth real percentage points of after-tax return.

FAQs

Can I pay myself a salary or claim my time as a cost?

No — a sole proprietor (which is what an individual trader is) cannot deduct their own labour; the profit IS your compensation. What you CAN structure: genuinely borrowed trading capital (interest deductible), family members genuinely employed for the business at market rates, or eventually a partnership/company structure — but at retail scale the complexity rarely beats the simple expense menu.
