Buyback Tax Calculator: Deemed Dividend and Capital Loss
Work out your real tax on a share buyback under the correct regime for your payout date, model the deemed capital loss that offsets it, and see whether tendering into the buyback or simply selling on the market leaves you richer.
Deemed Dividend Model: Buyback Liability and Loss Set-Off
How Share Buybacks Are Taxed in India
To understand where things stand, you need the three phases. Until 30 September 2024, the company undertaking the buyback paid a Buyback Distribution Tax under Section 115QA, roughly 23 percent including surcharge and cess, and the shareholder received the proceeds completely tax-free under Section 10(34A). For investors, especially those in high tax brackets, this made buybacks a genuinely tax-efficient way for companies to return cash, far better than a dividend that would be taxed at slab rates.
The government saw that gap and closed it. The Finance (No. 2) Act 2024 shifted the entire tax burden from the company to the shareholder with effect from 1 October 2024.
A new clause, Section 2(22)(f), was inserted into the definition of dividend so that the whole consideration you receive on a buyback is now a deemed dividend, taxed in your hands as income from other sources at your applicable slab rate. Crucially, you cannot deduct your cost of acquisition from this deemed dividend, so the full amount you receive, not just your profit, is taxed.
There is one relieving feature. Because the buyback is deemed a dividend, the sale consideration for capital gains purposes is treated as nil, which means your entire cost of acquisition becomes a deemed capital loss.
You can set this loss off against other capital gains in the same year, or carry it forward for up to eight years. If you have other capital gains to absorb it, this loss has real rupee value that reduces your overall tax, which is why this calculator models it explicitly rather than ignoring it as most tools do.
This deemed-dividend regime is punitive for retail investors, and the government has already legislated its reversal. Under the Income-tax Act 2025, effective from 1 April 2026, buyback proceeds return to the capital gains regime.
From that date, only your actual gain, the consideration minus your cost, is taxed, at 12.5 percent for long-term holdings or 20 percent for short-term, and your cost is fully allowed. This restores the more sensible treatment and removes the harsh feature of taxing your whole investment as if it were pure income. You can read the governing provisions on the Income Tax Department and the market rules on SEBI.
The company must deduct tax at source under the current regime. For resident shareholders, TDS applies at 10 percent under Section 194 once the total dividend, including this deemed dividend, crosses 10,000 rupees in the financial year, a threshold raised from 5,000 by Budget 2025.
Without a PAN, the rate is 20 percent. For non-resident shareholders, TDS under Section 195 applies at 20 percent, or a lower rate under an applicable tax treaty. This TDS is an advance payment credited against your final liability, not the final tax itself.
The single most important practical question this raises is whether to participate in a buyback at all. Under the current regime, tendering your shares means the whole amount is taxed as dividend at your slab, whereas selling the same shares on the exchange taxes only your gain at 12.5 percent. Unless the buyback price is meaningfully above the prevailing market price, selling on the market is now usually the cheaper route, and this calculator quantifies that difference for your exact situation.
It is worth understanding why companies still announce buybacks despite the harsher shareholder tax. A buyback reduces the number of shares outstanding, which lifts earnings per share and can support the share price, and it signals management’s confidence that the stock is undervalued. These corporate motives are separate from your personal tax outcome. So even when a buyback makes sense for the company, it does not automatically make sense for you to tender into it rather than sell on the open market. Treat the buyback offer as one exit route among two, compare the after-tax proceeds of each, and choose the one that leaves more in your pocket. The company’s rationale for the buyback should not drive your personal decision.
How the Buyback Tax Is Worked Out
Identify the Regime From Your Payout Date
The calculator first applies the correct rule based on when your buyback proceeds are paid. If paid until 30 September 2024, the proceeds are exempt in your hands and you owe nothing, since the company paid the tax.
If paid between 1 October 2024 and 31 March 2026, the current deemed-dividend regime applies. If paid on or after 1 April 2026, the restored capital gains regime applies. Getting the regime right is the whole game, because the three treatments produce wildly different tax outcomes for the identical buyback, and stale calculators that assume a single permanent rule mislead you badly.
Tax the Full Consideration as Deemed Dividend
Under the current regime, the calculator treats your entire buyback consideration, the shares tendered multiplied by the buyback price, as a deemed dividend. It then computes the tax by the marginal method: your tax on total income including this deemed dividend, minus your tax on your other income, so the dividend is taxed at your true marginal slab.
No deduction is allowed for your cost of acquisition against this amount. It applies the current slabs, surcharge where relevant, and the 4 percent cess, and for NRIs applies the flat 20 percent under Section 195 instead.
Model the Deemed Capital Loss
Because the sale consideration for capital gains is deemed nil under the current regime, your full cost of acquisition becomes a deemed capital loss. The calculator computes this loss and, if you entered other capital gains for the year, works out how much tax it saves you by offsetting those gains, typically at the 12.5 percent long-term rate.
This saving is subtracted from your deemed-dividend tax to give your true net liability. If you have no other gains, the loss can only carry forward up to eight years, so the calculator flags that it saves nothing this year and your effective tax is the full dividend tax.
Compare Against Selling on the Market
Finally, under the current regime, the calculator compares your net buyback tax against what you would pay by simply selling the same shares on the exchange, where only your actual gain is taxed at 12.5 percent long-term capital gains, above the 1.25 lakh annual exemption. It declares which route is cheaper and by how much.
For most retail investors the market sale wins comfortably, because taxing only the gain at a flat low rate beats taxing the whole consideration at slab. The exception is when the buyback price carries a large premium over the market price, which the calculator lets you test directly.
The Three Buyback Tax Regimes at a Glance
The table below sets out how buyback taxation has changed. The regime that applies to you depends solely on the date the proceeds are paid, not when the buyback was announced.
| Period | Who Pays | How Taxed |
|---|---|---|
| Until 30 Sep 2024 | Company (115QA) | Shareholder exempt (10(34A)) |
| 1 Oct 2024 to 31 Mar 2026 | Shareholder | Full consideration as deemed dividend, slab rate |
| From 1 Apr 2026 | Shareholder | Capital gains on actual gain only |
The current middle regime is the harshest for investors. Under it, the deemed capital loss is the only relief, and only if you have other capital gains to absorb it. The table below shows the key rules of the current regime that this calculator applies.
| Rule | Detail |
|---|---|
| Taxable amount | Entire consideration, not just gain |
| Head of income | Deemed dividend, income from other sources |
| Cost deduction | Not allowed against dividend |
| Cost treatment | Deemed capital loss, carry forward 8 years |
| TDS resident | 10 percent above 10,000 (Section 194) |
| TDS no PAN | 20 percent |
| TDS NRI | 20 percent (Section 195) or treaty rate |
| Surcharge | Applies, capped 15 percent for dividends |
| Cess | 4 percent on tax |
Real Buyback Tax Examples: Pune, Hyderabad, and Kolkata
These three examples show the current regime, the deemed capital loss, and the buyback-versus-market decision with real rupee figures. Each can be reproduced above.
Anand, a Pune investor in the 25 percent bracket, tendered 500 shares in a company buyback at 300 rupees each, having bought them at 100. His consideration was 1.5 lakh and his actual profit only 1 lakh. He assumed, reasonably, that he would be taxed on his 1 lakh gain.
The current regime shocked him. Because the buyback is a deemed dividend, the entire 1.5 lakh was added to his income and taxed at his marginal slab, not just the 1 lakh profit.
The tax came to about 26,000 rupees with cess, an effective 17 percent on his consideration but a punishing rate relative to his real gain. His 50,000 cost gave no deduction against this.
Anand did learn one silver lining: his 50,000 cost became a deemed capital loss. Since he had booked some equity gains elsewhere that year, he could set the loss off against them, saving a further 6,250 rupees at the 12.5 percent rate. But the core lesson stung: under this regime a buyback taxes your whole investment as income, not your profit.
Priya, a Hyderabad investor in the 30 percent bracket, held 1000 shares bought at 200, and the company announced a buyback at 800. Her consideration would be 8 lakh, her gain 6 lakh. She could tender into the buyback or sell the same shares on the exchange, where the market price was close to the buyback price.
The comparison was stark. Tendering into the buyback taxed the whole 8 lakh as deemed dividend, about 2.29 lakh before her deemed loss and 2.04 lakh after using it, an effective rate over 25 percent. Selling on the market taxed only her 6 lakh gain at 12.5 percent long-term capital gains, above the 1.25 lakh exemption, coming to just 59,375 rupees.
Priya sold on the market and saved over 1.44 lakh in tax for the identical cash outcome. Her case captures the defining feature of the current regime: unless the buyback price carries a large premium over the market, a retail investor is almost always better off selling on the exchange, because only the gain is taxed there, and at a far lower flat rate.
Ramesh, a Kolkata investor, faced the same numbers as Priya but for a buyback with proceeds paid on or after 1 April 2026, when the Income-tax Act 2025 restores capital gains treatment. He wanted to know how the new regime would change his outcome.
Under the restored regime, only his actual 6 lakh gain is taxed, at 12.5 percent long-term capital gains above the 1.25 lakh exemption, coming to 59,375 rupees, exactly what a market sale would cost. The full consideration is no longer taxed as dividend, and his cost is properly allowed against the proceeds rather than shunted into a deemed loss.
Ramesh saw that the 2026 regime effectively removes the penalty of the current rules and puts buybacks back on the same footing as an ordinary sale. His case illustrates why the government reversed the deemed-dividend approach: it had made buybacks harshly expensive for shareholders, taxing capital, not just profit, and the capital gains treatment is far fairer.
Six Ways to Handle a Buyback Smartly
Compare Buyback Against a Market Sale First
Before tendering into any buyback under the current regime, compare it against simply selling your shares on the exchange. Tendering taxes your whole consideration as dividend at your slab, while a market sale taxes only your gain at 12.5 percent long-term capital gains.
Unless the buyback price is meaningfully higher than the prevailing market price, the market sale is almost always cheaper for a retail investor. Run both routes through this calculator with your actual numbers before deciding. The difference can run into lakhs for a large holding, and it is entirely within your control which route you take.
Use the Deemed Capital Loss Deliberately
If you do participate in a buyback under the current regime, remember that your full cost becomes a deemed capital loss. This loss is only valuable if you have other capital gains to set it off against, in the same year or within the next eight.
Plan to book some capital gains, for example by selling appreciated shares or funds, in a year when you have a large deemed loss, so the loss is not wasted. Coordinating your buyback participation with your other capital gains can meaningfully reduce your overall tax. Keep clear records so you can carry the loss forward correctly if you cannot use it immediately.
Check the Buyback Payout Date, Not the Announcement
The tax regime that applies to you depends on when the buyback proceeds are actually paid, not when the buyback is announced or when you tender. A buyback announced in early 2026 but paid on or after 1 April 2026 falls under the far more favourable capital gains regime, while one paid before that date is caught by the punitive deemed-dividend rules.
If you have flexibility, understanding this timing can materially change your tax. Read the buyback offer document carefully for the expected settlement date, and factor it into your decision to tender.
Submit Your PAN to Avoid 20 Percent TDS
Ensure your PAN is registered and linked to Aadhaar with the company or registrar before a buyback. Under the current regime, TDS on the deemed dividend is 10 percent with a valid PAN but 20 percent without one, or if your PAN is inoperative due to non-linking with Aadhaar.
That doubles the tax withheld and locks up your cash until you file and claim the excess back. This is entirely avoidable with a quick check of your demat and folio records. Eligible resident shareholders with income below the taxable threshold can also submit Form 15G or 15H to avoid TDS altogether.
Remember TDS Is Not Your Final Tax
The 10 percent TDS deducted on a buyback under the current regime is only an advance payment, not your final liability. Your actual tax depends on your slab, which for most participants is higher than 10 percent, so you will owe a balance when you file, and possibly advance tax during the year to avoid interest.
Never treat the post-TDS amount as settled. Include the full deemed dividend in your return, reconcile the TDS from your Form 26AS, and pay any shortfall. This calculator shows your true net liability so you can plan for the balance rather than being surprised at filing.
Factor In Your Slab Before Tendering
Under the current regime, the pain of a buyback rises sharply with your tax slab, because the whole consideration is taxed at your marginal rate. A shareholder in the 30 percent bracket loses far more of a buyback to tax than one in the 5 percent bracket.
If you are a high earner, the case for selling on the market rather than tendering is even stronger, since the flat 12.5 percent capital gains rate is well below your slab. Conversely, a very low-slab investor with other gains to absorb the deemed loss may find the buyback less punishing. Always run your own slab through the numbers.

Frequently Asked Questions About Buyback Tax
These questions cover the three regimes, the deemed capital loss, TDS, and the buyback-versus-market decision for residents and NRIs.
How is a share buyback taxed in India now?
Under the current regime, from 1 October 2024 to 31 March 2026, your entire buyback consideration is treated as a deemed dividend under Section 2(22)(f) and taxed at your applicable slab rate as income from other sources. You cannot deduct your cost of acquisition against this amount, so the full sum you receive, not just your profit, is taxed.
Your cost instead becomes a deemed capital loss that you can set off against other capital gains. This is a significant change from the earlier regime, where the company paid the tax and shareholders received proceeds tax-free, and from the 2026 regime, where only the gain is taxed as capital gains.
What are the three buyback tax regimes?
Buyback taxation has passed through three phases. Until 30 September 2024, the company paid Buyback Distribution Tax under Section 115QA and the shareholder was exempt under Section 10(34A).
From 1 October 2024 to 31 March 2026, the Finance (No. 2) Act 2024 shifted the burden to the shareholder, taxing the whole consideration as a deemed dividend at slab rates. From 1 April 2026, the Income-tax Act 2025 restores capital gains treatment, taxing only the actual gain. The regime that applies to you depends solely on when your buyback proceeds are paid, so identifying the correct payout date is essential to computing your tax correctly.
What is the deemed capital loss?
Under the current regime, because your buyback proceeds are taxed entirely as a deemed dividend, the sale consideration for capital gains purposes is treated as nil. This means your full cost of acquisition becomes a deemed capital loss.
For example, if you bought shares for 50,000 and tendered them in a buyback, that 50,000 becomes a capital loss even though you received money for the shares. You can set this loss off against other capital gains in the same year, or carry it forward for up to eight years. If you have other gains to absorb it, the loss reduces your overall tax; if not, it simply waits to be used in a future year.
Is a buyback or a market sale better for me?
Under the current regime, selling on the market is usually better for retail investors. If you tender into a buyback, your whole consideration is taxed as dividend at your slab rate, which can be 30 percent plus surcharge and cess.
If you sell the same shares on the exchange, only your actual gain is taxed, at 12.5 percent long-term capital gains above the 1.25 lakh exemption. Unless the buyback price is meaningfully higher than the market price, the market sale leaves you with more after tax, often dramatically so for high-slab investors. This calculator compares both routes for your exact numbers so you can decide before tendering.
Why did the government change buyback taxation?
After the Dividend Distribution Tax was abolished in 2020, dividends became taxable at the shareholder’s slab rate, but buybacks continued to attract only a flat company-level tax under Section 115QA. This made buybacks far more tax-efficient than dividends for shareholders in high brackets, creating an incentive for companies to return cash through buybacks rather than dividends.
The government moved to close this gap through the Finance (No. 2) Act 2024, shifting the tax to shareholders and taxing the whole consideration as a deemed dividend. However, this proved harsh, taxing capital rather than just profit, so the Income-tax Act 2025 restored capital gains treatment from April 2026.
What TDS applies to a buyback?
Under the current regime, because buyback proceeds are a deemed dividend, the company deducts TDS under Section 194 at 10 percent for resident shareholders once the total dividend, including this deemed dividend, exceeds 10,000 rupees in the financial year, a threshold raised from 5,000 by Budget 2025. Without a valid PAN, or if your PAN is inoperative due to non-linking with Aadhaar, the rate is 20 percent under Section 206AA.
For non-resident shareholders, TDS applies at 20 percent under Section 195, or a lower rate under an applicable tax treaty. Eligible resident shareholders with income below the taxable threshold can submit Form 15G or 15H to avoid TDS. This TDS is an advance payment, not your final tax.
Can I deduct my cost of acquisition in a buyback?
Not against the deemed dividend under the current regime. From 1 October 2024 to 31 March 2026, your entire buyback consideration is taxed as a deemed dividend with no deduction for cost, so you cannot reduce the taxable amount by what you paid for the shares.
Instead, your cost becomes a deemed capital loss that can offset other capital gains. This is a key harshness of the current regime and the main reason it is unpopular with investors: you are taxed on your whole investment, not just your profit. From 1 April 2026, when capital gains treatment is restored, your cost is fully allowed and only your actual gain is taxed, which is far more favourable.
How were buybacks taxed before October 2024?
Until 30 September 2024, the company undertaking the buyback paid Buyback Distribution Tax under Section 115QA, at roughly 23 percent including surcharge and cess, on the difference between the buyback price and the amount originally received for the shares. The shareholder received the proceeds completely tax-free under Section 10(34A), with no capital gains consequences.
This made buybacks a tax-efficient way for companies to return cash to shareholders, especially those in high tax brackets, since a dividend of the same amount would have been taxed at slab rates in the shareholder’s hands. This regime ended for buybacks paid on or after 1 October 2024.
What happens to buyback tax from April 2026?
From 1 April 2026, under the Income-tax Act 2025, buyback proceeds return to the capital gains regime. The deemed dividend treatment under Section 2(22)(f) is removed for buybacks whose consideration is paid on or after that date.
Instead, only your actual gain, the consideration minus your cost of acquisition, is taxed, at 12.5 percent for long-term holdings or 20 percent for short-term. Your cost is fully allowed against the proceeds, and there is no deemed capital loss because the sale is treated normally. This is far more favourable than the current regime, restoring buybacks to the same tax footing as an ordinary market sale of shares.
How are NRIs taxed on a buyback?
Under the current regime, non-resident shareholders participating in a buyback face TDS under Section 195 at 20 percent on the deemed dividend, plus applicable surcharge and cess, with no threshold, though a lower rate may apply under the Double Taxation Avoidance Agreement between India and the NRI’s country of residence. To claim a treaty rate, the NRI must furnish a Tax Residency Certificate, PAN, and other documentation.
As with residents, the whole consideration is taxed as deemed dividend, not just the gain. NRIs should also check whether the same income is taxed again in their home country, where DTAA relief or a foreign tax credit may apply. This calculator applies the flat 20 percent for NRIs by default.
Do I need to report a buyback in my tax return?
Yes. Under the current regime you must report the deemed dividend from the buyback as income from other sources in your income tax return, and report the deemed capital loss under capital gains so you can set it off or carry it forward.
Even though TDS was deducted, that is only an advance payment, and your final liability depends on your slab, so you must reconcile it and pay any balance. Failing to report a buyback correctly can lead to a notice or penalty, since the transaction is visible in your Form 26AS and annual information statement. Keep records of the shares tendered, your cost, and the consideration received to support accurate reporting.
Does surcharge apply to buyback income?
Yes, if your total income is high enough to attract surcharge, it applies to the tax on your deemed dividend from a buyback. However, as with other dividend income, the surcharge on the deemed dividend is capped at 15 percent even if your income would otherwise attract higher surcharge rates of 25 or 37 percent.
This cap prevents the buyback income from being taxed at punitive combined rates for very high earners. The 4 percent health and education cess then applies on top of the tax plus surcharge. This calculator applies the surcharge where relevant and respects the 15 percent cap on the deemed dividend component.
Can I use the deemed loss if I have no other gains?
If you have no other capital gains in the year of the buyback, you cannot use the deemed capital loss immediately, but you do not lose it. The loss is carried forward for up to eight assessment years and can be set off against capital gains in any of those future years.
So while it saves you nothing in the current year, making your effective buyback tax the full deemed-dividend amount, it retains value if you expect to book capital gains later. This is why this calculator asks for your other capital gains: with none entered, it correctly shows the loss saving nothing now and flags that it carries forward. Plan future gains to absorb it.
Is the buyback taxed differently for listed and unlisted shares?
The deemed-dividend treatment under the current regime applies to buybacks by domestic companies generally, both listed and unlisted, so the core tax mechanism is the same: the whole consideration is taxed as a deemed dividend and the cost becomes a deemed capital loss. The main practical difference lies in the market-sale alternative.
For listed shares, you can readily sell on the exchange and pay only 12.5 percent long-term capital gains on your gain, which is usually cheaper than tendering. For unlisted shares, there may be no ready market to sell into, so tendering into the buyback may be your only route to exit, even though the tax is harsher. This calculator focuses on the tax computation, which is common to both.
What is Section 2(22)(f)?
Section 2(22)(f) is the clause inserted into the Income-tax Act by the Finance (No. 2) Act 2024 that expanded the definition of dividend to include any payment a company makes to buy back its own shares from a shareholder. This is the legal basis for treating buyback proceeds as a deemed dividend in the shareholder’s hands from 1 October 2024.
By classifying the buyback as a dividend rather than a capital transaction, the provision ensures the whole consideration is taxed at slab rates with no cost deduction. The Income-tax Act 2025 removes this clause for buybacks paid on or after 1 April 2026, returning them to capital gains treatment. Understanding this clause explains why the current regime taxes your full consideration.
How does this calculator go beyond a basic buyback tool?
Most sources on buyback tax are articles, not calculators, and those that compute anything usually apply a single regime and ignore the deemed capital loss. This calculator applies the correct rule for your payout date across all three regimes, computes the deemed-dividend tax by the marginal method on top of your other income with the current slabs, surcharge, and cess, and models the deemed capital loss, quantifying how much it saves when set off against your other capital gains.
Above all, it runs a buyback-versus-market-sale comparison showing which route leaves you richer, the decision that actually matters when a buyback is announced. It handles the Budget 2025 TDS threshold, no-PAN, and NRI cases too.
Which Calculators Pair With Buyback Tax?
Disclaimer and Editorial Transparency
This buyback tax calculator provides indicative estimates from the values you enter, and is for informational and educational purposes only. It does not constitute tax or investment advice.
The tax computation applies the rules of the regime you select, using current slabs, a simplified surcharge treatment capped at 15 percent for the deemed dividend, and the 4 percent cess, but your actual liability depends on your complete income, deductions, other capital gains, and circumstances. The deemed capital loss saving assumes you can set the loss off against the other capital gains you enter, taxed at the long-term equity rate; your actual set-off depends on the nature and timing of those gains.
Tax laws change, and the regime applicable to a buyback depends on the precise date proceeds are paid. The treatment of listed versus unlisted shares, promoter versus non-promoter status, NRI taxation and DTAA relief, surcharge and marginal relief for high incomes, and the interaction with your other income can be complex.
The buyback-versus-market comparison assumes you could realise a similar price on the exchange, which may not hold for illiquid or unlisted shares. Nothing here is a substitute for professional advice.
Before tendering into a buyback or filing your return, consult a qualified chartered accountant and verify current rules with the official portal. For authoritative details, refer to the Income Tax Department and SEBI.
