Module: Module 1 — Foundations of Indian Income Tax
1. Introduction
Income-tax calculation involves more than multiplying income by a percentage. A taxpayer must first determine the correct total income, identify the applicable tax regime, separate income taxed at normal slab rates from income taxed at special rates, and then consider rebate, surcharge, cess and other relevant provisions.
This chapter explains the principal concepts and calculations for Tax Year 2026–27, which runs from 1 April 2026 to 31 March 2027. The Income-tax Act, 2025 uses the term “tax year” in place of the earlier framework’s previous-year and assessment-year terminology for the new Act. Where older terminology remains useful for comparison, it is identified as such.
This material is intended for learning and revision. A real tax computation must be based on the taxpayer’s complete facts and the law applicable to that taxpayer.
2. Learning Objectives – Income Tax Slabs FY 2026-27
After studying this chapter, you should be able to:
- explain income-tax rates, slabs and tax regimes;
- identify the default new tax regime and understand when an option to use the normal regime may be available;
- apply the new-regime slabs for Tax Year 2026–27;
- understand the commonly used normal/old-regime slabs for individuals;
- distinguish an exemption, deduction, rebate and special-rate provision;
- explain rebate under Section 156 of the Income-tax Act, 2025 and the concept of marginal relief;
- understand surcharge and Health and Education Cess;
- calculate illustrative tax before final adjustments; and
- recognise common errors in examination questions and tax preparation.
3. What Is an Income-Tax Rate?
An income-tax rate is the percentage used to calculate tax on a particular amount of taxable income. For example, if a portion of income is taxable at 10%, the tax on that portion is calculated by multiplying that portion by 10%.
For income subject to progressive slab rates, the applicable percentage changes as the income moves through the slabs. The highest slab rate therefore does not normally apply to every rupee of total income.
4. What Is a Tax Slab?
A tax slab is a defined range of total income to which a specified rate applies. Under a progressive system, each rate is applied to the relevant portion of income within that slab.
| Total income under the new regime | Rate |
| Up to ₹4,00,000 | Nil |
| ₹4,00,001–₹8,00,000 | 5% |
| ₹8,00,001–₹12,00,000 | 10% |
| ₹12,00,001–₹16,00,000 | 15% |
| ₹16,00,001–₹20,00,000 | 20% |
| ₹20,00,001–₹24,00,000 | 25% |
| Above ₹24,00,000 | 30% |
These are the normal slab rates under Section 202 of the Income-tax Act, 2025 for Tax Year 2026–27. Special provisions may apply to particular categories of income.
5. Tax Rate, Tax Slab and Tax Regime: The Difference
| Term | Meaning | Example |
| Tax slab | The income range | ₹8 lakh to ₹12 lakh |
| Tax rate | The percentage applicable to a slab | 10% |
| Tax regime | The wider set of rules governing rates, exemptions, deductions and options | New regime or normal regime |
Remember: a slab is a range, a rate is a percentage, and a regime is the overall taxation framework.
6. The New Tax Regime and Default Status
For eligible taxpayers, the new tax regime is the default regime. Section 202 of the Income-tax Act, 2025 provides the relevant rates for Tax Year 2026–27. A taxpayer who wishes to use the normal regime must follow the applicable option rules. The procedure and timing can differ depending on whether the taxpayer has income from business or profession.
Do not assume that the choice is freely interchangeable in every situation. Taxpayers with business or professional income should check the applicable statutory option, prescribed form and filing requirements for their facts.
7. New-Regime Slabs for Tax Year 2026–27
The new-regime slab sequence is ₹4 lakh, ₹8 lakh, ₹12 lakh, ₹16 lakh, ₹20 lakh and ₹24 lakh, with rates of 0%, 5%, 10%, 15%, 20%, 25% and 30%, respectively.
| Slab | Income portion | Rate |
| 1 | First ₹4,00,000 | 0% |
| 2 | Next ₹4,00,000 | 5% |
| 3 | Next ₹4,00,000 | 10% |
| 4 | Next ₹4,00,000 | 15% |
| 5 | Next ₹4,00,000 | 20% |
| 6 | Next ₹4,00,000 | 25% |
| 7 | Amount above ₹24,00,000 | 30% |
The table describes normal slab-rate taxation. Income subject to a specific rate under another provision must be identified separately.
8. Worked Example: Total Income of ₹10 Lakh
Assume an eligible taxpayer has total income of ₹10,00,000, all of which is taxable at the normal new-regime slab rates. Ignore special-rate income and other adjustments for this illustration.
The correct slab tax is ₹40,000, not ₹10,00,000 multiplied by 10%. If the taxpayer is a resident individual who meets the conditions for the applicable rebate, the rebate provisions must then be considered. Do not assume the final tax payable from slab tax alone.
9. Total Income Is Not the Same as Gross Receipts
Tax slabs are generally applied to total income determined under the applicable provisions, not automatically to gross salary, gross receipts or total money deposited into a bank account.
A simplified sequence is:
- Identify income and receipts from relevant sources.
- Compute income under the applicable heads of income.
- Apply the relevant adjustments and deductions allowed by law.
- Determine total income.
- Separate normal slab-rate income from income taxable at special rates where required.
- Calculate tax and consider rebate, surcharge, cess and other applicable provisions.
This is a simplified learning model. The precise computation order and treatment depend on the nature of income and applicable statutory provisions.
10. Connection with Earlier Chapters
Chapter 3 — Residential Status: residential status helps determine the scope of income taxable in India.
Chapter 4 — Scope of Total Income: the scope provisions help identify which income enters the Indian tax computation.
Chapter 5 — Exempt Income: qualifying exempt income is treated according to the relevant exemption provision and should not simply be treated as ordinary taxable income.
These topics should be understood before applying tax rates. Add the actual internal links to the published chapters in WordPress.
11. Normal/Old Tax Regime: Common Individual Slabs
The term “old regime” is commonly used for the normal tax-rate structure available when a taxpayer validly uses the normal regime. For individuals, the basic exemption threshold under this structure depends on age and residential status as prescribed by the applicable rules.
| Individual category | Total income | Rate |
| Individual below 60 years | Up to ₹2,50,000 | Nil |
| Individual below 60 years | ₹2,50,001–₹5,00,000 | 5% |
| Individual below 60 years | ₹5,00,001–₹10,00,000 | 20% |
| Individual below 60 years | Above ₹10,00,000 | 30% |
| Resident senior citizen aged 60 to below 80 | Up to ₹3,00,000 | Nil |
| Resident senior citizen aged 60 to below 80 | ₹3,00,001–₹5,00,000 | 5% |
| Resident senior citizen aged 60 to below 80 | ₹5,00,001–₹10,00,000 | 20% |
| Resident senior citizen aged 60 to below 80 | Above ₹10,00,000 | 30% |
| Resident super senior citizen aged 80 or more | Up to ₹5,00,000 | Nil |
| Resident super senior citizen aged 80 or more | ₹5,00,001–₹10,00,000 | 20% |
| Resident super senior citizen aged 80 or more | Above ₹10,00,000 | 30% |
These are the commonly applicable normal-regime individual slabs. The higher basic exemption thresholds shown for senior citizens are tied to the relevant residence and age conditions. Confirm the applicable rules for the specific tax year and taxpayer.
12. New Regime vs Normal Regime
| Feature | New regime | Normal/old regime |
| Default status | Default for eligible taxpayers | Applies when validly selected under the rules |
| Slab structure | Seven principal rate bands for Tax Year 2026–27 | Fewer principal slabs for individuals |
| Basic exemption | ₹4 lakh under the new-regime slabs | Generally ₹2.5 lakh, ₹3 lakh or ₹5 lakh depending on category |
| Specified deductions and exemptions | Many are restricted; only permitted items can be claimed | A broader range may be available subject to conditions |
| Rebate | Section 156 applies subject to conditions | Different rebate limits and conditions apply |
| Regime selection | Default unless a valid option applies | Option procedure depends on the taxpayer’s circumstances |
Do not choose a regime solely by comparing the highest tax rate. Calculate the tax under each regime that is legally available, using the taxpayer’s actual deductions, exemptions, income types and rebate eligibility.
13. Deductions and Exemptions: Why Regime Choice Matters
The new regime restricts many deductions and exemptions available under the normal regime, although certain specified deductions or adjustments may remain permitted. The exact treatment must be checked against the relevant provisions.
A regime comparison should therefore consider the complete tax computation, not just the slab percentages. A deduction that is available under one regime may not be available under the other.
14. Rebate Under Section 156 of the Income-tax Act, 2025
For Tax Year 2026–27, use the Section 156 reference under the Income-tax Act, 2025. Section 87A is the familiar reference under the earlier Income-tax Act, 1961 framework and should not be used as the operative section number for this chapter’s new-Act discussion.
Under Section 156, a resident individual may qualify for a rebate subject to the statutory conditions. For income chargeable under Section 202(1), the provision includes a rebate of 100% of the relevant income tax or ₹60,000, whichever is less, where total income does not exceed ₹12,00,000. The Act also provides a marginal-relief mechanism for qualifying income above ₹12,00,000. The rebate is subject to the statutory limit and does not mean every component of tax, including all special-rate tax, is automatically eliminated.
For income not exceeding ₹5,00,000, Section 156 also contains a separate rebate rule with a maximum of ₹12,500, subject to the provision’s conditions. Always identify which part of Section 156 applies.
The rebate is a reduction from eligible income tax after the tax has been computed; it is not the same as an exemption or a deduction from income.
15. Example: How a Rebate Works
Assume an eligible resident individual has ₹10,00,000 of total income, all taxed at normal new-regime slab rates, and the slab tax is ₹40,000. If the individual qualifies for the full rebate and no restriction prevents the rebate from applying to that tax, the calculation may be:
| Particulars | Amount |
| Tax before rebate | ₹40,000 |
| Less: eligible rebate under Section 156 | ₹40,000 |
| Tax after rebate | ₹0 |
This illustration does not mean that every taxpayer with income of ₹12 lakh or less has no tax in every circumstance. Income taxed at special rates and other statutory limitations must be checked.
16. Marginal Relief – Income Tax Slabs FY 2026-27
Marginal relief is intended to prevent a sharp and disproportionate increase in tax around a specified threshold. Under the new-regime rebate rules, qualifying resident individuals whose total income exceeds ₹12,00,000 may be entitled to marginal relief where the statutory test is met.
The basic approach is to calculate the tax under the relevant provisions and then compare it with the limit prescribed for marginal relief. Do not assume that the rebate simply disappears in every case once income exceeds ₹12 lakh; equally, do not assume that relief always applies. Check the statutory conditions and the actual computation.
17. Special-Rate Income
Some income is taxable at rates prescribed specifically for that type of income rather than ordinary slab rates. Examples may include certain capital gains, lottery or other winnings, and other categories identified in the law.
When a question includes such income, identify the governing provision before applying the ordinary slabs. The final calculation may need to combine tax on normal-rate income with tax on special-rate income. The availability and calculation of rebates can also be affected by the applicable rules.
For this reason, a tax computation should not assume that every rupee included in total income is taxed at the normal slab rate.
18. Surcharge
Surcharge is an additional charge on income tax when the taxpayer’s total income exceeds specified thresholds and the applicable rules impose it. It is generally calculated on income tax, not by multiplying total income directly by the surcharge percentage.
Thresholds and rates depend on the taxpayer, the applicable regime and the nature of income. The relevant provisions may also cap surcharge for certain income or provide marginal relief. For a real calculation, consult the applicable Finance Act and the Income-tax Act provisions for the tax year instead of relying on a generic threshold list.
19. Health and Education Cess
Health and Education Cess is generally calculated at 4% of income tax plus applicable surcharge, subject to the rules governing the particular case.
| Particulars | Amount |
| Income tax after applicable rebate | ₹1,00,000 |
| Surcharge | ₹0 |
| Cess at 4% of ₹1,00,000 | ₹4,000 |
| Illustrative total | ₹1,04,000 |
This example assumes there is no surcharge and the stated ₹1,00,000 is the amount of income tax on which cess is calculated. In a real computation, use the correct tax after the applicable rebate and surcharge rules.
20. Complete Tax Calculation Flow
The order above is a study aid. Follow the applicable statutory computation rules for the taxpayer’s facts.
21. Worked Example: Total Income of ₹15 Lakh
Assume total income of ₹15,00,000 is entirely subject to the normal slab rates under the new regime.
| Income portion | Rate | Tax |
| First ₹4,00,000 | 0% | ₹0 |
| Next ₹4,00,000 | 5% | ₹20,000 |
| Next ₹4,00,000 | 10% | ₹40,000 |
| Remaining ₹3,00,000 | 15% | ₹45,000 |
| Total slab tax before subsequent adjustments | ₹1,05,000 |
The final liability depends on rebate eligibility, any special-rate income, surcharge, cess and other relevant provisions. Do not present ₹1,05,000 as the final tax payable without applying the relevant checks.
22. Worked Example: Total Income of ₹25 Lakh
Assume total income of ₹25,00,000 is entirely subject to the normal slab rates under the new regime.
| Income portion | Rate | Tax |
| First ₹4,00,000 | 0% | ₹0 |
| Next ₹4,00,000 | 5% | ₹20,000 |
| Next ₹4,00,000 | 10% | ₹40,000 |
| Next ₹4,00,000 | 15% | ₹60,000 |
| Next ₹4,00,000 | 20% | ₹80,000 |
| Next ₹4,00,000 | 25% | ₹1,00,000 |
| Remaining ₹1,00,000 | 30% | ₹30,000 |
| Total slab tax before subsequent adjustments | ₹3,30,000 |
The 30% rate applies to the portion above ₹24 lakh, not the entire ₹25 lakh.
23. Effective Tax Rate and Marginal Tax Rate
The effective tax rate is the tax amount divided by the relevant total-income figure, expressed as a percentage. The marginal tax rate is the rate applicable to the next portion of income within the relevant slab, subject to special-rate rules.
For example, using the illustrative slab tax of ₹3,30,000 on total income of ₹25,00,000:
Effective rate before rebate, surcharge and cess = ₹3,30,000 ÷ ₹25,00,000 × 100 = 13.2%.
The marginal normal slab rate on the portion above ₹24 lakh is 30%. The effective rate and marginal rate answer different questions.
24. Comparing Regimes: A Practical Method
- Determine the regimes legally available to the taxpayer.
- Calculate total income separately under each regime, applying only deductions and exemptions permitted under that regime.
- Identify special-rate income and calculate it under the relevant provisions.
- Calculate tax under each regime.
- Apply the appropriate rebate and marginal-relief rules.
- Add surcharge and cess where applicable.
- Compare the final liabilities and consider procedural requirements before selecting or confirming the regime.
This is a framework, not a universal recommendation. The most suitable regime depends on the taxpayer’s facts and the applicable law.
25. Business and Professional Income: Special Care
Taxpayers with income from business or profession may face different requirements for opting out of the default regime, including prescribed procedures and deadlines. The process should not be assumed to be identical to that for a taxpayer with salary and other non-business income only.
Before advising a taxpayer or answering an examination question, verify the applicable option provisions, return-filing requirements and any prescribed form.
26. Connection with Salary Income
Chapter 7 covers Income from Salary. Salary tax computation may involve basic salary, allowances, perquisites, retirement benefits, eligible exemptions, standard deduction and other relevant adjustments before the total income and final tax are determined.
A simplified salary calculation is: gross salary → identify taxable and exempt components → compute income from salary after applicable deductions → combine with other income → determine total income → apply the relevant tax provisions.
The treatment of each salary component depends on the applicable regime and statutory conditions.

30. Case Study: Correct Method of Calculation
Rahul has total income of ₹18,00,000, assumed entirely subject to the new-regime normal slab rates. He calculates tax by multiplying ₹18,00,000 by 30%, arriving at ₹5,40,000.
Is his method correct? No. The normal slab calculation is:
| Income portion | Rate | Tax |
| First ₹4,00,000 | 0% | ₹0 |
| Next ₹4,00,000 | 5% | ₹20,000 |
| Next ₹4,00,000 | 10% | ₹40,000 |
| Next ₹4,00,000 | 15% | ₹60,000 |
| Remaining ₹2,00,000 | 20% | ₹40,000 |
| Total slab tax before subsequent adjustments | ₹1,60,000 |
The example shows why the highest rate should not be applied to the entire income under progressive slab taxation. The final liability still requires all applicable rebate, special-rate, surcharge and cess checks.

33. Frequently Asked Questions
What is the new tax regime for Tax Year 2026–27?
It is the default regime for eligible taxpayers, with slab rates under Section 202 of the Income-tax Act, 2025.
What is the first slab under the new regime?
Total income up to ₹4,00,000 is generally taxed at a nil slab rate.
Does a 30% slab mean the taxpayer pays 30% of all income?
No. Under progressive normal slab rates, each rate applies to the relevant portion of income.
Can an eligible taxpayer get a rebate when total income is up to ₹12 lakh?
A resident individual may qualify for the rebate under Section 156, subject to statutory conditions and limitations.
What happens when total income is slightly above ₹12 lakh?
Marginal relief may apply if the statutory conditions are satisfied. The actual calculation must be checked.
Is the new regime always better than the old regime?
No. Compare the final liability under each regime available to the taxpayer, including deductions, exemptions, rebate and other relevant rules.
Are capital gains always taxed at slab rates?
No. Certain capital gains are subject to special rates.
When should this chapter be reviewed?
Review it whenever the relevant law, rates, official instructions or tax-filing procedures change.
34. Chapter Summary
Tax rates convert taxable income into income tax, but correct tax computation begins with determining total income and identifying the relevant provisions. For Tax Year 2026–27, the new regime under Section 202 uses seven principal slab rates: 0%, 5%, 10%, 15%, 20%, 25% and 30%.
The normal/old regime remains relevant where a taxpayer validly uses it under the applicable rules. A reliable comparison must consider the complete computation, including permitted deductions and exemptions, special-rate income, rebate, marginal relief, surcharge and cess.
For the new Income-tax Act framework, Section 156 is the relevant rebate reference; Section 87A belongs to the earlier Act framework. Always verify statutory conditions before calculating a taxpayer’s final liability.
The key examination principle is simple: do not apply the highest slab rate to the whole of normal slab-rate income. Calculate progressively and then apply the remaining provisions.
