1. Architecture of the Tax Rate System in FY 2025-26
1.1 Dual Regime for Individuals and Similar Entities
For individuals, HUFs, AOPs, BOIs and Artificial Juridical Persons, the law
offers two alternative ways to compute tax:
-
The Old Regime with traditional slabs and a wide universe
of exemptions and deductions;
-
The New Regime under section 115BAC(1A), which is the
default option, offering lower, more granular slabs but with most
exemptions and deductions switched off.
The taxpayer’s core choice is therefore not simply “rate” but “rate +
deduction structure”. The same total income can be taxed under either regime
with different final results.
1.2 Entity-wise Rate Blocks
Beyond individuals and HUFs, the Act uses separate rate blocks:
-
Firms / LLPs – taxed at a flat rate on total income;
-
Co-operative societies – small slab then 30%;
-
Domestic companies – 25% or 30% in the normal route,
plus optional regimes at 25%, 22% or 15%;
-
Foreign companies – a nominal 35% rate with surcharge
slabs.
These rates are then layered with surcharge and 4% Health & Education
Cess, plus special rules like AMT/MAT where applicable.
2. Old Regime Slab Rates – Individuals & HUFs
2.1 Individuals Below 60 and Non-Residents
Under the old regime, for resident individuals below 60 years and all
non-resident individuals (irrespective of age), the slabs are:
- Up to ₹2,50,000 – Nil;
- ₹2,50,001 to ₹5,00,000 – 5%;
- ₹5,00,001 to ₹10,00,000 – 20%;
- Above ₹10,00,000 – 30%.
The same slabs also apply to HUFs, AOPs, BOIs and AJPs when they remain
under the old regime instead of opting for the new one.
2.2 Resident Senior Citizens (60–<80 Years)
For resident individuals aged 60 years or more but less than 80 years at any
time during the year:
- Up to ₹3,00,000 – Nil;
- ₹3,00,001 to ₹5,00,000 – 5%;
- ₹5,00,001 to ₹10,00,000 – 20%;
- Above ₹10,00,000 – 30%.
The higher basic exemption recognises the need to lessen tax pressure on
post-retirement incomes while keeping the same 5–20–30% progression beyond
that point.
2.3 Resident Super Senior Citizens (80 Years and Above)
Resident individuals aged 80 years or more at any time during the year enjoy
an even higher zero-tax band:
- Up to ₹5,00,000 – Nil;
- ₹5,00,001 to ₹10,00,000 – 20%;
- Above ₹10,00,000 – 30%.
There is no 5% slab; tax starts directly at 20% once income crosses ₹5 lakh.
2.4 Rebate Under Section 87A in the Old Regime
In the old regime, a resident individual with total income up to ₹5,00,000
can avail rebate under section 87A, up to a maximum of ₹12,500. This
effectively makes tax liability Nil for total income up to
₹5 lakh (before cess).
This rebate is not available to non-residents and operates before cess but
after computing basic tax on the slab.
3. New Regime u/s 115BAC(1A) – Default for AY 2026-27
3.1 Who Is Covered and How It Works
The new regime is the default regime for:
- Individuals (residents and non-residents);
- HUFs;
- AOPs, BOIs; and
- Artificial Juridical Persons.
A taxpayer who prefers the old regime must consciously opt for it in the
manner prescribed. Under the new regime:
- Many familiar exemptions and deductions are not allowed;
- Slab rates are lower and more finely spaced;
- There is no alternate minimum tax (AMT) for those under this regime.
3.2 New Regime Slab Structure – FY 2025-26
Under section 115BAC(1A), the slab rates for AY 2026-27 are:
- Up to ₹4,00,000 – Nil;
- ₹4,00,001 to ₹8,00,000 – 5%;
- ₹8,00,001 to ₹12,00,000 – 10%;
- ₹12,00,001 to ₹16,00,000 – 15%;
- ₹16,00,001 to ₹20,00,000 – 20%;
- ₹20,00,001 to ₹24,00,000 – 25%;
- Above ₹24,00,000 – 30%.
Instead of sharp spikes at ₹5 lakh and ₹10 lakh, the burden moves smoothly
upward, making the new regime more progressive and predictable across the
middle-income spectrum.
3.3 Rebate and Marginal Relief Under New Regime
Under the new regime, a resident individual with total income up to
₹7,00,000 is eligible for an enhanced rebate under section 87A, up to
₹60,000. This can make the final tax outgo effectively zero up to that
threshold.
A marginal relief mechanism operates near ₹7 lakh so that a small increase
in income just above ₹7,00,000 does not cause a disproportionately large
jump in tax. The additional tax over the rebate zone is adjusted to ensure
that it does not exceed the additional income itself.
3.4 What You Give Up in the New Regime
To access these lower slab rates, taxpayers under the new regime compute
income without many classic tax-planning tools, such as:
- House Rent Allowance (HRA) exemption;
- Leave Travel Allowance (LTA);
-
Interest on housing loan for self-occupied property (as a deduction from
income from house property);
- Most Chapter VI-A deductions like 80C, 80D, 80G and others;
- SEZ deduction and several business incentive deductions.
The philosophy is to swap complex deduction-based planning for a simpler,
lower-rate environment.
4. Surcharge, Health & Education Cess and AMT/MAT
4.1 Surcharge on Individuals & HUFs – Old Regime
Under the old regime, individuals and HUFs pay surcharge on income tax at
the following levels:
- 10% of tax if total income exceeds ₹50 lakh up to ₹1 crore;
- 15% of tax if income exceeds ₹1 crore up to ₹2 crore;
- 25% if income exceeds ₹2 crore up to ₹5 crore;
- 37% if income exceeds ₹5 crore.
Surcharge on certain long-term capital gains and dividend income is capped
at 15%. Marginal relief ensures that the total increase in tax plus
surcharge at a threshold does not exceed the incremental income beyond that
threshold.
4.2 Surcharge in the New Regime
For taxpayers under the new regime, the surcharge structure is simplified:
- 10% of tax if income exceeds ₹50 lakh up to ₹1 crore;
- 15% if income exceeds ₹1 crore up to ₹2 crore;
- 25% if income exceeds ₹2 crore.
Again, surcharge on specific capital gains and dividend income is generally
restricted to 15%, and marginal relief ensures smooth transitions across
the thresholds.
4.3 Health & Education Cess
Across regimes and categories (unless specially exempted), Health &
Education Cess is levied at 4% on the sum of income tax and surcharge:
Final tax = (Income Tax + Surcharge) × 1.04
4.4 Alternate Minimum Tax (AMT) and Minimum Alternate Tax (MAT)
Alternate Minimum Tax (AMT) at 18.5% of adjusted total income applies to
certain non-corporate taxpayers who claim specified deductions, but does not
apply to those who opt for the new regime under section 115BAC(1A).
Minimum Alternate Tax (MAT) at 15% of book profits generally applies to
companies, but companies that have opted for the special corporate regimes
under sections 115BAA or 115BAB are exempt from MAT.
5. Tax Rates for Firms, LLPs and Other Non-Corporate Entities
5.1 Partnership Firms and LLPs
A partnership firm or LLP, whether resident or non-resident, is taxed at:
- 30% on total income;
- 12% surcharge if total income exceeds ₹1 crore;
- 4% cess on tax plus surcharge.
AMT at 18.5% of adjusted total income may apply if the firm or LLP claims
specified deductions that trigger AMT provisions.
5.2 HUFs, AOPs, BOIs, AJPs
Hindu Undivided Families (HUFs), Associations of Persons (AOPs), Bodies of
Individuals (BOIs) and Artificial Juridical Persons (AJPs) follow:
-
The old individual slab (2.5–5–10 lakh thresholds with 5–20–30% bands)
when under the old regime; or
-
The new regime slab (0–4 lakh Nil, then 5%, 10%, 15%, 20%, 25%, 30%)
when under section 115BAC(1A).
This alignment keeps their rate framework parallel to that of individual
taxpayers, while still treating the entity as a separate taxable person.
6. Corporate Tax Rates – Domestic Companies
6.1 Normal Domestic Company Rates
For domestic companies in AY 2026-27, the standard corporate tax structure
is:
-
25% tax if turnover or gross receipts of FY 2023-24 do not exceed
₹400 crore;
- 30% tax for all other domestic companies.
Surcharge applies as:
- 7% of tax if total income exceeds ₹1 crore up to ₹10 crore;
- 12% of tax if total income exceeds ₹10 crore.
After tax and surcharge, 4% Health & Education Cess is added, with
marginal relief at surcharge thresholds.
6.2 Optional Special Corporate Regimes
Domestic companies have access to optional concessional regimes:
-
Section 115BA: 25% for certain manufacturing companies
(rarely used now due to more attractive options);
-
Section 115BAA: 22% for domestic companies that give up
specified incentives and deductions; surcharge is a flat 10%;
-
Section 115BAB: 15% for new manufacturing companies meeting
strict conditions on incorporation, commencement and activity mix, with
10% surcharge.
Companies under 115BAA or 115BAB are not subject to MAT, making these
regimes attractive for high-profit, low-incentive structures.
7. Foreign Companies and Co-operative Societies
7.1 Foreign Companies
Foreign companies are taxed at:
- 35% on total income;
- 2% surcharge if income exceeds ₹1 crore up to ₹10 crore;
- 5% surcharge if income exceeds ₹10 crore;
- 4% cess on tax plus surcharge.
MAT may apply to foreign companies with book profits and a taxable presence
in India, subject to treaty and permanent establishment considerations.
7.2 Co-operative Societies
Co-operative societies follow a three-step slab:
- Up to ₹10,000 – 10%;
- ₹10,001 to ₹20,000 – 20%;
- Above ₹20,000 – 30%.
Surcharge and cess apply on top, and separate concessional regimes for
certain co-operatives may exist (for example, lower flat rates subject to
conditions), providing targeted relief to well-defined sectors.
8. Special Income Rates – Capital Gains, Lotteries and Casual Income
Beyond the normal slabs and flat rates, certain types of income carry
special tax rates that override general slabs:
8.1 Capital Gains
Capital gains taxation hinges on holding period and asset type:
-
Short-term capital gains on listed equity and equity mutual funds,
where securities transaction tax (STT) is paid, are usually taxed at
15% under a dedicated section;
-
Long-term capital gains on certain assets are taxed at 10% or 20%,
depending on whether indexation is permitted and the nature of the
asset (listed equity, debt, property, etc.);
-
Surcharge on some long-term capital gains and specified income streams
is capped at 15%, even for very high-income taxpayers.
These special rates apply irrespective of the general regime (old or new)
that the individual or entity uses for other income.
8.2 Lotteries, Gaming, Betting and Similar Incomes
Winnings from lotteries, game shows, gambling, betting, horse races and
online gaming are generally taxed at a flat 30%, without slab benefits and
often without the ability to set off losses from such activities against
other heads of income.
For such income, the TDS rate of 30% effectively mirrors the final tax
rate, with separate sections dealing with TDS on each type of winning.
9. Comparing Old vs New Regime for Individuals
9.1 Old Regime – Deduction-Oriented
The old regime is traditionally suited to taxpayers who:
- Make full use of 80C, 80D, 80G and other deductions;
- Have significant HRA-based rent exemptions and LTA claims;
- Pay housing loan interest on self-occupied property;
- Benefit from age-based higher basic exemption (senior and super senior).
However, the old regime also produces more abrupt tax jumps and demands
careful documentation and planning throughout the year.
9.2 New Regime – Rate-Oriented and Simpler
The new regime, in contrast, favours taxpayers who:
- Have simpler financial arrangements with few deductions;
- Do not wish to lock funds into long-term tax-saving instruments;
- Prefer predictable, lower slab rates and easier monthly TDS patterns.
The nil tax up to ₹4 lakh, followed by gradual bands of 5%, 10%, 15%, 20%,
25% and 30%, makes the system especially attractive for middle incomes
where deduction scope is limited.
9.3 Strategic Decision Framework
A simple strategic lens is:
If your total deductions and exemptions are substantial,
the old regime often leads to lower tax. If they are
modest or minimal, the new regime usually
wins, especially with the enhanced rebate and smoother slabs.
For taxpayers with business or professional income, switching rules between
regimes are more restrictive. Once you opt out of the old regime in certain
years, you may be barred from returning, so the decision must be evaluated
carefully over a multi-year horizon.
10. Conclusion – Reading the FY 2025-26 Tax Rate Landscape
For Financial Year 2025-26 (Assessment Year 2026-27), India’s income tax
rate system is best viewed as a structured matrix:
-
Who you are: individual, HUF, firm, company, co-operative
or foreign company;
-
Which regime you use: old deductions-based or new slab-based
for individuals and similar entities;
-
What kind of income you earn: business/professional, salary,
capital gains, casual winnings, etc.;
-
How high your income is: which triggers surcharge and
marginal relief.
Once this matrix is understood, the tax rate numbers become the final plug
into a well-defined logic rather than an overwhelming list. The move to
make the new regime the default, while preserving the old regime as an
option, reflects a policy direction towards simplicity and transparency,
but leaves room for classic tax planning where it still makes sense.
From a Zerolev perspective, the most effective taxpayers are those who first
choose the right regime and entity structure,
and only then worry about the exact slab and surcharge percentage. The
numbers are important, but strategy sits above arithmetic.
