Important Tax Disclaimer

This income tax calculator is intended for general estimation and educational purposes. Tax liability can depend on the taxpayer's complete facts, nature of income, deductions, exemptions, special-rate income, residential status, applicable tax regime, surcharge, rebate, cess, amendments and other provisions.

The result should not be treated as a legal opinion, final tax assessment or guaranteed tax liability. Before filing a return or making an important tax decision, verify the calculation against the latest official Income Tax Department information and, where appropriate, consult a qualified tax professional.

Quick Answer

An income tax calculator estimates your tax payable by applying the applicable tax rates to taxable income, reducing eligible rebates where applicable, adding surcharge when applicable, and then adding 4% Health & Education Cess on income tax plus surcharge. For individuals, the calculator can compare the old and new tax regimes for FY 2025-26 (AY 2026-27).

Summary

The Income Tax Calculator FY 2025-26 on this page is designed for more than a simple salary-tax calculation. It provides a broader calculation framework where you can select the type of taxpayer, residential status, age category where relevant, applicable section or special tax regime, taxable income, and deductions.

For individuals and HUFs, the calculator can show the estimated liability under both old and new regimes. This makes it easier to compare the effect of deductions and different slab structures before deciding which calculation is more beneficial.

For eligible taxpayers, the calculation can also include surcharge, rebate and Health & Education Cess. The final result is intended as an estimate and should be checked against the applicable Income-tax Act provisions, notifications, rules, and the official income-tax portal before filing or making a final payment decision.

💰 The most useful way to use the calculator is to enter accurate taxable-income figures rather than simply entering your CTC or gross receipts and assuming that the result is your final legal tax liability.

What Is an Income Tax Calculator?

An income tax calculator is an online tool that estimates the amount of income tax payable on taxable income. Instead of manually applying tax slabs, rebates, surcharge and cess, the calculator performs the calculation automatically based on the information entered by the user.

A basic calculator may only calculate tax on taxable income. A more advanced calculator can consider taxpayer type, age, residential status, deductions, tax regime, special tax sections, surcharge and cess.

The calculator on this page is designed around the second approach. It provides separate inputs for taxpayer classification and applicable tax provisions so that different types of taxpayers can be handled more appropriately.

---

How Does the Income Tax Calculator Work?

The calculator generally follows a sequence of tax-calculation steps. First, it identifies the taxpayer category and relevant tax regime. Next, it applies the applicable tax rate to taxable income. Where applicable, it considers rebate, surcharge and Health & Education Cess before arriving at the estimated net tax payable.

1. Enter the relevant income or taxable income.
2. Select the taxpayer category.
3. Select residential status where applicable.
4. Select the appropriate age category for individuals.
5. Enter eligible deductions where the selected regime permits them.
6. Select the applicable tax section or special regime where relevant.
7. Calculate tax under the applicable rules.
8. Apply eligible rebate.
9. Calculate surcharge, if applicable.
10. Add Health & Education Cess.
11. Display the estimated tax payable.

This process is important because income tax is not always calculated simply by multiplying total income by one percentage. Different portions of income may fall into different slabs, while certain taxpayers and special income categories can be subject to different rules.

---

Income Tax Calculator FY 2025-26: What Does FY and AY Mean?

FY 2025-26 means Financial Year 2025-26. It covers income earned from April 1, 2025 to March 31, 2026.

The corresponding Assessment Year is AY 2026-27. The assessment year is the year in which the income of the previous financial year is assessed and the applicable income-tax return is filed.

Therefore, searches such as “income tax calculator FY 2025-26” and “income tax calculator AY 2026-27” generally refer to the same financial year's income-tax calculation, although FY and AY are technically different concepts.

---

New Tax Regime Slabs for FY 2025-26

For AY 2026-27, the new tax regime under Section 115BAC has revised slab rates. The Income Tax Department lists the following normal slab structure for individuals under the new regime.

The slabs are progressive. This means that reaching a higher slab does not cause your entire income to be taxed at the highest rate. Each slab applies to the relevant portion of taxable income.

Example of New Regime Slab Calculation

Suppose taxable income is ₹15,00,000 under the new regime.

• ₹0 to ₹4,00,000 = Nil tax
• ₹4,00,001 to ₹8,00,000 = ₹20,000 at 5%
• ₹8,00,001 to ₹12,00,000 = ₹40,000 at 10%
• ₹12,00,001 to ₹15,00,000 = ₹45,000 at 15%
• Tax before rebate, surcharge and cess = ₹1,05,000

The actual final calculation can differ depending on the type of income, eligible rebate, special-rate income and other applicable provisions. The example demonstrates only the normal slab calculation.

---

Old Tax Regime Slabs for FY 2025-26

The old tax regime continues to use different slabs depending on the age category of an individual. The Income Tax Department states that the old-regime basic exemption thresholds differ for individuals below 60, senior citizens aged 60 or more but below 80, and super senior citizens aged 80 or more.

Old Regime: Individual Below 60 Years

Old Regime: Senior Citizen

Old Regime: Super Senior Citizen

For a non-resident individual, the old-regime slab treatment does not use the resident age-based basic exemption structure in the same way. This is one reason the calculator includes a residential-status option instead of assuming that every individual should be treated as a resident.

---

Old vs New Tax Regime in the Income Tax Calculator

The main advantage of comparing both regimes is that the old and new regimes can produce different results depending on deductions, exemptions, income level and taxpayer circumstances.

The new regime generally uses lower and more numerous slab rates but restricts many deductions and exemptions available under the old regime. The old regime can be useful for taxpayers with substantial eligible deductions and exemptions.

Instead of assuming that one regime is always better, enter your actual figures into the calculator and compare the estimated tax payable.

You can also read our detailed guide on Old vs New Tax Regime for a broader comparison.

How to Calculate Income Tax Online

Using the calculator is straightforward, but the accuracy of the result depends heavily on the information entered.

1. Select taxpayer type. Choose individual, HUF, AOP/BOI, firm/LLP, co-operative society, local authority, or domestic company as applicable.
2. Select residential status. Choose resident or non-resident where the calculator provides the option.
3. Select age category. For individuals, choose below 60, 60 to below 80, or 80 and above where applicable.
4. Enter taxable income. Enter the income figure relevant to the calculation.
5. Enter deductions. Enter eligible deductions if applicable, particularly when comparing the old regime.
6. Select applicable special section. If a special corporate or co-operative tax regime applies, select the relevant option.
7. Run the calculation. The tool calculates the estimated tax.
8. Compare results. Where applicable, compare old-regime and new-regime liabilities.

---

Gross Income vs Taxable Income

One of the most common mistakes when using an income tax calculator is confusing gross income with taxable income.

Gross income is the income before applicable deductions and certain adjustments. Taxable income is the amount on which tax is calculated after applying the relevant provisions.

For example, a salaried person may have salary income, interest income and other taxable income. Under a regime that permits particular deductions, eligible deductions can reduce taxable income.

Therefore, simply entering annual CTC into a calculator may not produce the same result as entering the correct taxable-income figure.

---

What Deductions Can Be Considered?

Deductions depend on the applicable tax regime and the nature of income. The old regime generally provides access to a wider range of deductions and exemptions, subject to the conditions of the relevant provisions.

Common deductions or exemptions that taxpayers may encounter include:

• 📌 Section 80C eligible investments and payments
• 📌 Section 80D medical-insurance related deduction
• 📌 Eligible home-loan interest provisions
• 📌 HRA exemption where applicable
• 📌 Other deductions available under the Income-tax Act

For a detailed explanation of Section 80C, see our Section 80C Deductions List.

For salaried taxpayers, you can also read Standard Deduction FY 2025-26 and our guide to HRA Exemption Calculation.

---

Standard Deduction and Income Tax Calculation

Standard deduction can affect the taxable income of eligible salaried individuals and pensioners. The exact treatment depends on the applicable tax regime and the nature of income.

This is why a salary-tax calculator should not simply multiply annual salary by a tax percentage. Salary income must first be processed according to the applicable provisions before the slab calculation is performed.

If your calculator asks for taxable income rather than gross salary, make sure the deductions and adjustments have been properly considered before entering the final taxable figure.

---

Section 87A Rebate in FY 2025-26

Section 87A can significantly reduce the tax payable for eligible resident individuals. For AY 2026-27, the Income Tax Department states that the rebate under the new regime can be up to ₹60,000 where total income does not exceed ₹12 lakh. Under the old regime, the maximum rebate is ₹12,500 where total income does not exceed ₹5 lakh.

The Section 87A calculation is important because a taxpayer may have a positive slab-tax amount before rebate but ultimately have no income tax payable after an eligible rebate.

For detailed rules, see Rebate under Section 87A FY 2025-26.

---

Surcharge in Income Tax Calculation

Surcharge is an additional charge on income tax that applies when total income crosses specified thresholds. It is calculated on the income-tax amount rather than simply being added directly to taxable income.

The Income Tax Department also provides marginal-relief provisions around surcharge thresholds. Certain special-rate income, including specified income under Sections 111A, 112 and 112A and certain dividend income, has restrictions on the enhanced surcharge rates.

This is one reason a comprehensive calculator should calculate surcharge separately instead of simply applying a single percentage to the entire income.

---

Marginal Relief in Income Tax

Marginal relief is intended to reduce the sharp increase in tax and surcharge that can occur when income just crosses a surcharge threshold. The relief broadly limits the additional tax and surcharge so that it does not exceed the additional income above the relevant threshold, subject to the applicable rules.

For example, where the applicable threshold is ₹50 lakh, a taxpayer whose income is only slightly above ₹50 lakh may qualify for marginal relief depending on the applicable provisions and calculation.

The Income Tax Department specifies marginal-relief limits for the relevant surcharge thresholds under the old and new regimes.

---

Health & Education Cess

After calculating income tax and applicable surcharge, Health & Education Cess is generally added at 4% of income tax plus surcharge for the applicable individual calculations.

The calculation can therefore be represented broadly as:

Final Tax Payable = Income Tax − Eligible Rebate + Surcharge + Health & Education Cess

The actual computation can contain additional rules depending on the taxpayer, type of income and applicable provisions.

---

Income Tax Calculation Example for a Salaried Individual

Suppose a resident individual below 60 years has taxable income of ₹15,00,000 and is considering the new tax regime.

A 4% cess on ₹1,05,000 would be ₹4,200, producing ₹1,09,200 before considering any other applicable adjustment. This simplified example assumes no rebate, surcharge or special-rate income.

The actual calculator result should always be based on the exact inputs and provisions applicable to the taxpayer.

---

Income Tax Calculator for Salary

A salary-based income tax calculation generally begins with salary income and then considers applicable deductions, exemptions and other income before arriving at taxable income.

For example, an employee may have:

• 💼 Basic salary
• 💼 HRA
• 💼 Special allowance
• 💼 Bonus
• 💼 Interest income
• 💼 Other taxable income
• 💼 Eligible deductions

The calculator should not be used by simply entering CTC and assuming that CTC equals taxable income. Employer contributions, benefits, exemptions, deductions and taxable components can affect the calculation.

---

Income Tax Calculator for HUF

A Hindu Undivided Family, or HUF, is a separate taxpayer category for income-tax purposes. The applicable calculation can differ from a simple individual salary calculation.

The calculator therefore includes HUF as a separate taxpayer selection rather than treating every non-company taxpayer as an individual.

Where an HUF is using the calculator, the user should enter the relevant taxable income and select the applicable regime and deductions based on the actual tax position.

---

Income Tax Calculator for AOP and BOI

AOP means Association of Persons and BOI means Body of Individuals. These entities have their own tax provisions, and the applicable rate can depend on the structure and relevant provisions.

For AY 2026-27, the Income Tax Department provides a new-regime slab structure for eligible AOP/BOI taxpayers that follows the revised slabs of ₹4 lakh, ₹8 lakh, ₹12 lakh, ₹16 lakh, ₹20 lakh and ₹24 lakh, subject to the applicable provisions.

AOP/BOI taxation can involve additional considerations such as Alternate Minimum Tax in applicable circumstances, so users should verify the final calculation when the entity has complex income or special provisions.

---

Income Tax Calculator for Firm and LLP

A firm or LLP is not calculated in the same way as an individual taxpayer under progressive individual slabs.

The Income Tax Department states that a firm is generally liable to income tax at a flat rate of 30% on total income, with a 12% surcharge where total income exceeds ₹1 crore, subject to marginal relief and applicable cess. LLP taxation similarly uses a flat 30% rate with applicable surcharge and cess.

This distinction is important when using a multi-taxpayer calculator. Selecting “Firm/LLP” should not be treated as simply applying the individual old-regime slab rates.

---

Income Tax Calculator for Co-operative Society

Co-operative societies can be subject to different tax rates depending on whether the normal provisions or an optional special regime applies.

The Income Tax Department provides a 22% alternative tax regime under Section 115BAD and a 15% regime for eligible new manufacturing co-operative societies under Section 115BAE, subject to the applicable conditions. These special regimes also have their own surcharge treatment.

Because eligibility for special regimes depends on statutory conditions, the calculator should be treated as an estimation tool and not as a substitute for checking whether the taxpayer actually qualifies for the selected section.

---

Income Tax Calculator for Local Authority

Local authorities are subject to a different tax framework from individuals. The Income Tax Department's tax-rate material states that local authorities are generally taxed at 30%, with surcharge where applicable and 4% Health & Education Cess on income tax and surcharge.

Selecting the correct taxpayer type is therefore essential when using a calculator that supports multiple entity categories.

---

Income Tax Calculator for Domestic Company

Domestic companies can have different tax rates depending on turnover, selected sections and eligibility.

The Income Tax Department confirms these rates for AY 2026-27. It also specifies separate surcharge treatment, including a 10% surcharge for companies opting for Sections 115BAA or 115BAB irrespective of total income.

---

Section 115BA in the Income Tax Calculator

Section 115BA is a special taxation provision for eligible domestic companies. Where the company qualifies and has selected the applicable regime, the tax rate is different from the standard 30% rate.

The calculator includes Section 115BA as an option so that eligible users can select the relevant tax treatment instead of manually applying a general domestic-company rate.

Section 115BAA in the Income Tax Calculator

Section 115BAA provides a concessional tax regime for eligible domestic companies. For AY 2026-27, the Income Tax Department lists a 22% income-tax rate under this section, with a 10% surcharge on the income tax and applicable cess.

The availability of the section depends on statutory conditions and the company's decision to opt for the regime.

Section 115BAB in the Income Tax Calculator

Section 115BAB provides a concessional rate for eligible new domestic manufacturing companies meeting specified conditions. The Income Tax Department lists the rate at 15% for AY 2026-27, with a 10% surcharge under the special regime.

Users should verify that the company satisfies the relevant conditions before relying on the calculated amount.

Section 115BAD for Co-operative Societies

Section 115BAD is an optional tax regime for eligible co-operative societies. The Income Tax Department's tax-rate material lists the income-tax rate at 22%, with a flat 10% surcharge on income tax under the regime.

Section 115BAE for New Manufacturing Co-operative Societies

Section 115BAE provides a concessional 15% rate for eligible new manufacturing or production co-operative societies subject to specified conditions. The section itself states that the option is available to qualifying resident co-operative societies when the statutory conditions are satisfied.

The calculator includes this option for users who need to estimate tax under the relevant special regime, but eligibility should always be verified separately.

Tax Calculation for Residents and Non-Residents

Residential status can affect income-tax treatment. An individual should not automatically select “resident” merely because they live or work in India without considering the applicable residential-status rules.

The calculator therefore provides a residential-status selection. Users should select the status that applies under the Income-tax Act for the relevant financial year.

For complex residential-status questions, foreign income, treaty relief or DTAA issues, professional tax advice may be appropriate.

Why Age Matters Under the Old Tax Regime

Age can affect the basic exemption threshold under the old regime for resident individuals. The old regime distinguishes between individuals below 60, senior citizens aged 60 or more but below 80, and super senior citizens aged 80 or more.

The new regime does not use the same age-based slab structure. Therefore, the calculator asks for age where required instead of assuming that age is irrelevant to every tax calculation.

Income Tax Calculator and Special Rate Income

Not every type of income necessarily follows the normal slab structure. Certain capital gains, lottery winnings, specified dividends and other categories may have special tax rates.

This is an important limitation to understand when using any simplified income tax calculator. If your income contains substantial special-rate income, the final tax return calculation may require separate treatment of those income components.

For this reason, the calculator should be treated as an estimate unless the underlying tool specifically models every special-rate provision applicable to your income.

Income Tax Calculator vs Income Tax Slab Calculator

An income tax slab calculator generally focuses on applying tax rates to taxable income. A broader income tax calculator can include deductions, rebate, surcharge, cess, taxpayer classification, age, residence and special tax regimes.

This page is intended to provide the broader calculation approach. For a detailed explanation of the actual slab structures, see our Income Tax Slab FY 2025-26 guide.

Income Tax Calculator vs Tax Filing

An income tax calculator estimates tax. It does not itself constitute an income tax return or complete the filing process unless the tool is specifically integrated with an authorized filing system.

If you need to file an actual return, see our How to File Income Tax Return Online guide.

You can also check our guide on Which ITR Form Should You File? to understand the broad differences between ITR forms.

When Should You Not Rely Only on an Online Calculator?

An online calculator is useful for estimates, planning and comparisons, but certain tax situations can require detailed professional review.

• 📌 Multiple sources of complex income
• 📌 Significant capital gains
• 📌 Foreign income or foreign assets
• 📌 DTAA or treaty issues
• 📌 Business or professional income with complex deductions
• 📌 Special company tax regimes
• 📌 AMT or MAT considerations
• 📌 Complex trust, AOP or entity taxation
• 📌 Tax disputes or notices
• 📌 Transactions involving special tax provisions

---

Is the Income Tax Calculator Accurate?

The calculator can provide a useful estimate when the correct inputs and applicable tax rules are incorporated. However, no online calculator should automatically be treated as a legally binding tax assessment.

Tax calculations can depend on income type, deductions, exemptions, residential status, special rates, rebates, surcharge, cess, applicable amendments and other facts. Always verify important calculations against the current Income Tax Department information and your actual tax records.

---

How the Calculator Calculates Net Tax Payable

For a simplified normal-tax calculation, the overall process can be represented as:

1. Determine taxable income.
2. Apply the relevant slab or applicable tax rate.
3. Calculate tax before rebate.
4. Subtract eligible rebate where applicable.
5. Calculate applicable surcharge.
6. Apply marginal relief where the applicable rules provide it.
7. Calculate Health & Education Cess.
8. Arrive at the estimated final tax liability.

Estimated Final Tax = Tax After Rebate + Surcharge + Health & Education Cess

This is a simplified representation. Special-rate income and special tax regimes can require additional calculations.
