Nobody tells you about the tax part when you open a Demat account. You learn about buying shares, watching prices, booking profits, and then at the end of the financial year, the question hits: how much of this goes to income tax?

The answer depends on what you earned and how. Profits from selling stocks are taxed differently from dividends. Intraday gains follow completely different rules from delivery-based investing. And Budget 2024 changed several rates that even experienced investors are still catching up with.

This guide breaks down each income type from a Demat account and explains exactly what tax applies, with worked examples wherever the numbers tell the story better than words.

What Actually Gets Taxed in a Demat Account?

The account itself has no tax. What matters is the income you earn from the securities sitting inside it.

There are five income types to understand:

Profit from selling shares, mutual funds, or ETFs, this is capital gains
Dividends received from companies or mutual funds
Interest from bonds, Government Securities, or Sovereign Gold Bonds
Profits from intraday trades where you buy and sell on the same day
Profits from Futures and Options trading

Each one is treated as a separate head of income under the Income Tax Act. The tax rate on each can be very different, which is why understanding them individually matters.

Capital Gains Tax: The Holding Period Changes Everything

Short Term Capital Gains

Sell listed equity shares or equity mutual fund units within 12 months of buying them and the profit is called a Short Term Capital Gain (STCG).

From July 23, 2024, the STCG tax rate on listed equity, where STT was paid, is 20%, plus surcharge and cess. Before that date, it was 15%.

If STT was not paid, which happens with unlisted shares or certain off-market transactions, the gain gets added to your income and taxed at your slab rate instead.

Long Term Capital Gains

Hold the same shares or equity mutual funds for more than 12 months and the profit becomes a Long Term Capital Gain (LTCG).

Budget 2024 changed three things here at once, all from July 23, 2024:

The exemption limit moved from ₹1 lakh to ₹1.25 lakh per year
The tax rate went up from 10% to 12.5%
Indexation was removed, you can no longer inflate the purchase cost to reduce gains

Gains within ₹1.25 lakh in a year remain fully exempt. Anything beyond that is taxed at 12.5%.

STCG vs LTCG: Key Differences

	STCG	LTCG
Holding period	Less than 12 months	More than 12 months
Tax rate (from July 23, 2024)	20% with STT	12.5% on gains above ₹1.25 lakh
Yearly exemption	None	₹1.25 lakh
Indexation	Not applicable	Removed
Without STT	Slab rate	Slab rate

Calculating Capital Gains: Three Real Scenarios

Say you buy 400 shares at ₹250 each in April 2024. Total cost: ₹1,00,000.

Scenario A — Sold at ₹310 in October 2024 (6 months)

Sale value comes to ₹1,24,000. Profit is ₹24,000. That is STCG. Tax at 20% works out to ₹4,800.

Scenario B — Sold at ₹450 in July 2025 (15 months)

Sale value is ₹1,80,000. Profit is ₹80,000. Since you held it over 12 months, it is LTCG. The ₹80,000 is under the ₹1.25 lakh exemption, so no tax at all.

Scenario C — Same as B but the profit is ₹1,60,000

Only ₹35,000 is taxable (₹1,60,000 minus the ₹1,25,000 exemption). Tax at 12.5% on ₹35,000 = ₹4,375.

Bonus Shares: The Zero-Cost Trap Most Investors Miss

When a company gives you bonus shares, you pay nothing for them. No tax applies at the time of receiving them.

The problem shows up when you sell them.

Under the Income Tax Act, the cost of acquisition for bonus shares is zero. So the entire sale value, not just the profit over what you paid, becomes your taxable capital gain. And the holding period for these shares starts from the date they were allotted, not from when you bought the original shares.

Example:

You get 100 bonus shares in May 2024. In August 2024 you sell them at ₹200 each.

Sale value: ₹20,000. Cost: ₹0. Profit = ₹20,000. Held 3 months, so this is STCG. Tax at 20% = ₹4,000.

Had you waited until June 2025, past 12 months from allotment, that same ₹20,000 becomes LTCG. Since it stays under the ₹1.25 lakh exemption, no tax is owed.

Dividend Tax: Simple but Often Filed Wrong

Dividends are not tax-free. They are added to your income and taxed at your slab rate, the same way your salary is taxed.

TDS applies when dividends from a single company or fund cross ₹5,000 in a financial year. In that case, 10% is deducted before the money reaches you. If your PAN is not updated in the Demat account, that TDS rate doubles to 20%.

Below ₹5,000, no TDS is deducted. But that does not mean the dividend is exempt. Many investors assume no TDS means no tax, that is wrong. All dividend income, regardless of the amount, must be declared in your ITR.

The TDS that has already been deducted appears in Form 26AS. You claim it as a credit while filing.

Interest Income From Bonds and SGBs

Bonds, G-Secs, and Sovereign Gold Bonds (SGBs) can be held in your Demat account. The interest these generate is taxable as income from other sources at your applicable slab rate.

The SGB situation is frequently misunderstood. Here is the actual position:

The 2.5% annual interest the RBI pays on SGBs is taxable, always, no matter how long you hold
The capital gain at maturity redemption (after the full 8-year term) is completely exempt from tax
If you sell SGBs on the stock exchange before maturity, normal STCG or LTCG rules apply depending on how long you held them

Most investors think SGBs are entirely tax-free. They are not. Only the maturity gain is.

Intraday Trading: Not Capital Gains

This is where a lot of first-time traders get their taxes wrong. Intraday trading, buying and selling shares on the same day without taking delivery, is not treated as capital gains under Indian tax law.

The Income Tax Act classifies intraday profits as speculative business income. That means:

Tax at your full income slab rate, up to 30%
Losses from intraday trading can only be offset against speculative income from other intraday trades, not against your salary or capital gains from delivery trades
These losses can be carried forward for 4 years only (delivery-based capital losses get 8 years)
You must file ITR-3 if you have any intraday income, even if the amount is small

F&O Trading: Different Rules From Intraday

Futures and Options income is categorised as non-speculative business income, a different classification from intraday, with better loss treatment.

F&O profits are taxed at slab rate just like intraday, but the set-off rules are more flexible. F&O losses can be offset against any business income, not just speculative profits. And F&O losses carry forward for 8 years.

One more thing: if your F&O turnover crosses ₹10 crore in a year, a tax audit under Section 44AB becomes mandatory. ITR-3 applies here as well.

Debt Mutual Funds After April 2023

If you bought debt mutual funds before April 1, 2023, gains after a 2-year holding period still qualify for LTCG treatment.

For anything bought on or after April 1, 2023, the old LTCG-with-indexation benefit is gone. All gains, regardless of how long you hold, are added to your income and taxed at your slab rate.

This covers pure debt funds, hybrid funds with less than 35% equity, international funds, and Fund of Funds.

Equity-oriented funds, those with 65% or more in equity, are unaffected by this change and continue to follow the standard STCG and LTCG rules.

Capital Loss Set-Off and Tax Loss Harvesting

Selling at a loss is not always a bad outcome, it can reduce your tax bill for the year.

Short term capital losses can be offset against both STCG and LTCG. Long term capital losses can only go against LTCG, not against short term gains. Neither type can be offset against salary, dividends, or trading income.

Losses that cannot be used in the current year carry forward for up to 8 years. The one condition: you must file your ITR by July 31. File late and you permanently lose the carry-forward benefit for that year.

Tax loss harvesting is when investors intentionally book a loss on a falling stock near the financial year-end to offset gains made elsewhere in the same year. After booking the loss, they typically re-enter the same or a similar position. The tax saving is real, the approach is legal, and the portfolio exposure is maintained.

Section 87A and Capital Gains: An Important Clarification

For FY 2025-26, residents filing under the new tax regime with total income up to ₹12 lakh get a tax rebate of up to ₹60,000 under Section 87A, effectively making their tax liability zero.

But this rebate has a specific exclusion. It does not apply to special rate incomes, which includes STCG taxed at 20% and LTCG taxed at 12.5%.

To put it plainly: if your income is ₹10 lakh in salary and ₹50,000 in STCG from selling shares, the salary may attract no tax because of the rebate. The ₹50,000 STCG still gets taxed at 20%, giving a tax liability of ₹10,000. The rebate does nothing for that portion.

Advance Tax: Most Retail Investors Ignore This

When your total tax liability for the year is expected to exceed ₹10,000, advance tax must be paid in quarterly instalments, not in one shot at year-end.

Instalment	Due Date	% of Annual Tax
1st	June 15	15%
2nd	September 15	45% cumulative
3rd	December 15	75% cumulative
4th	March 15	100%

Miss these and interest under Section 234B and 234C runs at 1% per month from the missed date.

This catches investors who sell a large position in January, February, or March. The gain was realised late in the year but the advance tax clock started much earlier. If you realise a significant gain late in Q4, paying before March 15 stops further interest from building.

NRI Demat Account Holders: Where the Rules Differ

NRIs operate through either an NRO Demat account for India-sourced income or an NRE Demat account for foreign earnings.

Capital gains rates are the same as for residents, STCG at 20% and LTCG at 12.5% above ₹1.25 lakh. The difference is in TDS:

For NRIs, TDS on capital gains is deducted by the broker at source before the proceeds are credited, this does not happen for resident investors
Dividend TDS for NRIs is 20% versus 10% for residents
If a DTAA exists between India and the NRI’s country of residence, a lower TDS rate may apply under the treaty
Excess TDS deducted above actual tax liability can be claimed as a refund by filing an ITR in India

Interest on NRO accounts is subject to 30% TDS. Interest on NRE accounts is fully exempt from Indian income tax.

Are Demat Account Charges Tax Deductible?

For investors reporting capital gains:

Brokerage on buy and sell transactions adjusts your cost and sale price, which reduces your gain slightly, it is an indirect deduction
AMC charges are not deductible from capital gains under any provision
STT is not deductible, it is a government levy, not a cost of earning capital income
GST on brokerage at 18% is a service charge, also not deductible from capital gains

For intraday and F&O traders declaring business income, brokerage, STT, and related trading costs can be claimed as business expenses. The same charges that do nothing for an investor become deductible for a trader.

ELSS: Combining Tax Saving With Equity Investing

Equity Linked Savings Schemes (ELSS) give you a Section 80C deduction of up to ₹1.5 lakh per year. The lock-in period is 3 years.

On redemption, gains above ₹1.25 lakh are taxed at 12.5% under standard LTCG rules. For investors who want to put their 80C allocation to work in equities rather than keeping it parked in FDs or PPF, ELSS gives that option.

Which ITR Form Should You File?

Your Situation	ITR Form
Only salary and dividends, no capital gains	ITR-1
Capital gains from stocks or mutual funds, no business income	ITR-2
Intraday or F&O income	ITR-3
Capital gains along with intraday or F&O	ITR-3

Using ITR-1 when you have STCG or LTCG above ₹1.25 lakh is a defective filing. The Income Tax Department will flag it. ITR-2 is the correct form for most equity investors who are not trading intraday or F&O.

Mistakes That Cost Investors Money

Skipping dividend income below ₹5,000 in the ITR, no TDS does not mean no tax
Assuming the bonus share cost equals the original share price, it is zero
Thinking all SGB income is tax-free, only the maturity redemption gain is; the annual interest is taxable
Filing ITR-1 despite having capital gains to report
Filing after July 31 and losing the ability to carry forward losses
Not paying advance tax and getting interest notices months later
Leaving PAN unlinked in the Demat account, which pushes dividend TDS to 20%

Your Demat account income sits across multiple tax heads, capital gains, dividends, bond interest, speculative income, and business income. Budget 2024 moved STCG to 20% and LTCG to 12.5% with a ₹1.25 lakh exemption. Budget 2025 raised the Section 87A rebate threshold to ₹12 lakh but kept the restriction on applying it against special rate incomes. Getting the ITR form right, paying advance tax on time, and using loss set-off rules properly make a real difference to your actual tax outgo.
