Intraday Trading Tax Calculator
Intraday equity is speculative and F&O is not, so a loss in one cannot touch a profit in the other — but the restriction runs in only one direction.
What the Intraday tax calculator does
An intraday tax calculator shows what speculative treatment costs. Section 43(5) makes intraday equity speculative business income, taxed at your slab rate. An intraday loss cannot be set off against F&O profits, salary or any other income, and carries forward only four years, usable against future intraday profits alone.
Intraday is speculative. F&O is not. One proviso separates them.
Section 43(5) makes a transaction speculative where it is settled otherwise than by actual delivery. The provisos then carve out hedging, jobbing by a member of a recognised exchange, exchange-traded derivatives and commodity derivatives. Buying and selling equity shares within the day, as a retail client, is in none of those carve-outs.
So it stays speculative business income, while F&O — one proviso away — is not. A trader doing both, which is most of them, has two pools the Act will not let mix freely.
The rate, the deductible expenses and the turnover basis are all the same as F&O — slab plus cess, costs allowed, turnover as the sum of absolute differences. This page does not restate those. What it is about is the rules about which losses can reduce which gains, which are not the same at all.

Your inputs
The favourable differences across the year.
The unfavourable differences, as a positive number.
Brokerage, STT at 0.025% on the sell side, exchange and SEBI charges, GST, stamp duty. Deductible, as for any business.
Your separate, non-speculative pool. This is what makes the asymmetry visible — drag it either side of zero.
From an earlier year and still inside four. It can only ever meet an intraday profit.
Out of reach of any business loss, speculative or not. Shown so that is visible rather than assumed.
Interest, rent, business income. An F&O loss could reach this. A speculative loss cannot.
Your income tax slab
Speculative income is still business income, so it is taxed at your marginal rate.
Which tax regime are you on?
Carried for consistency with the other calculators; it does not change the rules about which losses can reduce which gains.
Will the return be filed by the due date?
Section 80 forfeits the carry-forward where the return misses the section 139(1) date.
What being speculative costs you this year
₹74,880
Your intraday loss of ₹2,40,000 cannot be used to reduce anything at all this year. Had these been F&O trades, one proviso away, ₹2,40,000 of it would have been used immediately against the ₹4,00,000 of non-salary income in your other pools.

The same two numbers, the other way round, cost ₹18,720
Section 73(1) says a loss in a speculation business may be used to reduce only against the profits of another speculation business. Nothing in the Act restricts the traffic the other way, so an ordinary F&O loss can be used to reduce an intraday profit.
That asymmetry is nearly invisible as a sentence, so here it is on your own figures with the two pools exchanged — whatever intraday did, F&O does instead.
As you actually traded
₹93,600
Intraday loss of ₹2,40,000, F&O profit of ₹3,00,000.
With the two pools swapped
₹18,720
The identical amounts, with the intraday and F&O results exchanged.
Difference
₹74,880
Purely from which pool the loss landed in. Nothing else changed.
Your loss is in the speculative pool, which is the expensive place for it to be. It cannot reach your F&O profit of ₹3,00,000, so that profit is taxed in full. Had the loss been the F&O one, it would have been set off and the bill would have been ₹18,720.

4 years, and only against another intraday profit
Section 73(4) carries a speculative loss forward 4 years, against speculative profits and nothing else. The same loss as F&O would get 8 years and could meet any business income — 4 more years and a far wider target.
Used to reduce anything this year
₹0
Nothing. A speculative loss reaches no other income at all, whatever else you earn.
Carried forward
₹2,40,000
For 4 years, usable only against a future intraday profit.
Contingent value
₹74,880
⚠️ Only if you make an intraday profit within four years. Not money in hand.
Worth being blunt about the third figure. A carried-forward F&O loss is close to money, because most traders have some business income for it to meet. A carried-forward speculative loss needs a future intraday profit specifically, inside four years, and SEBI’s own studies find the large majority of individual traders do not produce one. It is a contingency, not an asset. It also decides what the ₹74,880 at the top of this page really is. Make an intraday profit inside four years and the loss is used after all, so that figure turns out to have been a cost of timing — tax paid years earlier than it needed to be. Never make one, and it was permanent.

Turnover for the audit test is ₹10,00,000
As for F&O, turnover under section 44AB is the sum of the absolute favourable and unfavourable differences — not the value of the shares that passed through your account, which on an intraday book is many times larger. The threshold is ₹10,00,00,000 where the cash test is met, which intraday trading always satisfies because it settles through a broker.
You also have an F&O stream. Speculative and non-speculative trading are separate pools for setting off losses, but they are not separate businesses for the audit test — section 44AB looks at your combined turnover. The ₹10,00,000 shown here is the intraday part only, so treat it as a floor rather than the answer.

What this assumes
- Intraday equity by a retail client. Proviso (c) to section 43(5) takes jobbing and arbitrage by a member of a recognised exchange out of speculation. A client trading through a broker is not a member, so the carve-out does not apply to them.
- Equity, not derivatives or commodities. Intraday positions in exchange-traded derivatives fall under proviso (d) and are non-speculative however briefly they are held. Commodity derivatives with CTT paid fall under proviso (e). Only intraday equity is speculative, which is why the two pools on this page exist at all.
- BTST and STBT are not modelled. Where a share is bought one day and sold the next, whether delivery was taken decides the treatment, and the position is genuinely contested where it was not. That boundary needs your contract notes rather than a slider.
- A flat marginal rate, and one F&O figure. The whole result is taxed at the rate you selected plus 4% cess rather than run through the slabs, and the F&O pool is entered as a single net number rather than computed. Surcharge is excluded.
- Delivery trading is a different regime entirely. Take delivery and the same share becomes a capital asset: 0.1% STT on both sides rather than 0.025% on the sell, capital gains rather than business income, and no expense deduction beyond transfer costs.
- Books of account may be required under section 44AA, and the return is ITR-3. Neither is priced here.
No returns are assured or guaranteed. Any illustration of returns is a mathematical projection, not a promise. Intraday trading is leveraged and SEBI’s own studies have found that the large majority of individual traders lose money at it.

How the intraday tax calculation works
Speculative income = (favourable − unfavourable differences) − expenses, taxed at SLAB. Loss set off ONLY against speculative profits, carried forward 4 years.
Section 43(5) makes a transaction speculative where it is settled otherwise than by actual delivery. The provisos carve out hedging, jobbing by a MEMBER of a recognised exchange, exchange-traded derivatives and commodity derivatives — and intraday buying and selling of equity shares by a retail client is in none of them, so it remains speculative business income. The rate is the trader's slab plus cess, expenses are deductible, and turnover for the section 44AB audit test is the sum of absolute differences rather than the value of shares that passed through the account. All of that is identical to F&O, which sits one proviso away. What is not identical is the set-off, and that is the whole of the difference. Section 73(1) allows a loss in a speculation business to be set off only against the profits of another speculation business, so an intraday loss cannot reach an F&O profit, a salary, interest, rent or a capital gain. It reaches nothing. But the restriction is written on the speculative LOSS and not on speculative income, so the traffic runs one way: an ordinary F&O loss can be set off against an intraday profit. The identical pair of numbers therefore produces completely different tax depending on which pool the loss landed in, and a trader running both books can pay full tax on one while a matching loss sits idle in the other. The carry-forward is weaker too. Section 73(4) gives four years against speculative profits only, where section 72 gives a non-speculative loss eight years against any business income. That distinction matters more than the years suggest, because using a carried-forward speculative loss requires making an intraday profit specifically, within four years, and SEBI's own studies find the large majority of individual traders do not produce one — so it is a contingency rather than an asset. Section 80 read with 139(3) then forfeits even that where the return misses the section 139(1) due date, which bites harder here than for F&O since there is no current-year set-off to fall back on. Where the same share is held to delivery none of this applies: it becomes a capital asset taxed at 20% short-term or 12.5% long-term, with STT at 0.1% on both sides instead of 0.025% on the sell, and no deduction for trading costs.
Frequently asked questions
Is intraday trading speculative income?
Yes, for a retail client trading equity shares. Section 43(5) makes a transaction speculative where it is settled otherwise than by actual delivery, and the provisos carve out hedging, jobbing by a member of a recognised exchange, exchange-traded derivatives and commodity derivatives. Intraday equity by someone trading through a broker is in none of those, so it stays speculative business income — taxed at your slab, but pooled separately from everything else.
Can I set off an intraday loss against my F&O profit?
No. Section 73(1) allows a speculation loss to be set off only against the profits of another speculation business. F&O is non-speculative, so an intraday loss cannot reach it — nor your salary, interest, rent or capital gains. The loss simply sits in the speculative pool while the F&O profit is taxed in full.
Can an F&O loss be set off against intraday profit?
Yes, and this surprises most traders. The restriction in section 73(1) is on the speculative loss, not on speculative income, so nothing stops an ordinary business loss being set off against a speculative profit. The traffic runs one way. The identical pair of numbers therefore produces completely different tax depending on which pool the loss lands in.
How long does an intraday loss carry forward?
Four years under section 73(4), and only against speculative profits. That is a materially weaker position than an F&O loss, which gets eight years under section 72 and can meet any business income. To use a carried-forward intraday loss you have to make an intraday profit specifically, within four years, and SEBI's own studies find most individual traders do not.
Do I lose the carry-forward if I file late?
Yes, entirely. Section 80 read with section 139(3) forfeits the carry-forward where the return is not filed by the section 139(1) due date, and a day late costs the same as a year late. It matters more here than for F&O, because the carry-forward is the only thing a speculative loss has — there is no current-year set-off to fall back on.
What is turnover for intraday trading?
The sum of the absolute favourable and unfavourable differences, exactly as for F&O — not the value of the shares that passed through your account, which on an intraday book is many times larger. The audit threshold is ₹10 crore where the cash test is met. Note that if you trade both intraday and F&O, section 44AB looks at your combined business turnover, not each pool separately.
Is intraday taxed differently from delivery trading?
Completely. Take delivery and the share is a capital asset: 20% short-term or 12.5% long-term after twelve months, STT at 0.1% on both sides, and no deduction for your costs beyond transfer expenses. Square off the same day and it is speculative business income at your slab, with STT at 0.025% on the sell side and your trading costs fully deductible. The same share, two regimes, decided by whether delivery happened.
