Tax on Trading P&L Calculator

How Trading Income is Taxed in India

Different types of trading activity are taxed differently under the Indian Income Tax Act. Understanding which head applies to your trades is critical to accurate tax filing.

Why intraday tax is not a capital gains calculation

This is the distinction that catches people out. Buying and selling the same stock on the same day never gives you delivery of the shares, so the profit is not a capital gain at all — it is speculative business income, and it is taxed at whatever slab rate applies to your total income rather than at the flat 20% that short-term capital gains attract.

The practical consequence runs both ways. A trader in a low slab pays less on intraday profit than on an equivalent short-term delivery gain. A trader in the 30% slab pays more. Either way, a calculator that treats intraday profit as STCG gives you the wrong number, which is why the field above is separate.

F&O is business income, not speculation

Futures and options are treated as non-speculative business income even though intraday equity is speculative. Both end up taxed at your slab rate, so the arithmetic on this page is the same for each, but the classification matters when you file: speculative and non-speculative income are reported separately and their losses are not interchangeable.

That last point is the one this calculator deliberately does not model. Set-off and carry-forward rules can change what you actually owe by a large margin — a speculative loss can only be set against speculative gains, non-speculative losses have wider scope, and both carry forward for a limited number of years. This page totals tax on profits. If you have losses in any bucket, treat the figure here as an upper bound and take the return itself to a CA.

What this estimate leaves out

• Loss set-off and carry-forward. Not applied. With losses in the mix your real liability is lower than the figure above.
• Surcharge. High-income surcharge on capital gains is not modelled; only the cess is.
• Your slab. The business income rate is an input, not a lookup. It does not compute your slab from total income or apply the rebate.
• Turnover-based obligations. Audit and bookkeeping requirements depend on turnover computed under specific rules, which this page does not calculate.

These limits are listed on the methodology page alongside every other assumption the site makes, rather than left for you to discover.

Frequently Asked Questions

• Can intraday losses be set off against other income?
  Speculative business losses from intraday equity generally cannot be set off against salary or capital gains. F&O business losses (non-speculative) can be set off against other business income. Loss set-off and carry-forward can materially change your tax outcome.
• Is a tax audit required for F&O traders?
  Tax audit depends on turnover, profit declaration, presumptive-tax eligibility, and whether lower profits are reported than the law permits without audit. Review Section 44AB and related guidance, or consult a CA if your trading turnover is material.
• Do I need to file ITR-3 for F&O trading?
  F&O income is generally treated as business income, so traders commonly file the business-income return form (typically ITR-3). The correct form and due date depend on your specific facts and whether a tax audit applies.
