Income Tax Slabs 2026-27: A Complete Guide for Salaried Employees
Every year, lakhs of salaried employees in India face the same critical decision during April-May: which tax regime to choose for the financial year ahead. The choice between the old tax regime (with deductions) and the new tax regime (with lower rates but no deductions) can mean a difference of ₹50,000 to ₹2,00,000 in annual tax liability, depending on your salary structure, investments, and expenses. Making the wrong choice is costly — once you file your ITR for a given financial year and choose a regime, you cannot switch back for that year.
This guide covers the complete income tax slab structure for FY 2026-27 (Assessment Year 2027-28), explains both regimes in detail with real-world examples, and provides a decision framework to help you choose the regime that minimises your tax liability. Use our CTC to In-Hand Salary Calculator to instantly compare your tax liability under both regimes with your exact salary and deduction details.
New Tax Regime Slabs for FY 2026-27 (Default Regime)
The new tax regime has been the default tax regime since FY 2023-24. If you do not explicitly opt for the old regime, your TDS is computed under the new regime. The government has progressively reduced rates and increased the rebate limit under the new regime over successive budgets. As of FY 2026-27, the slab structure under the new regime is as follows:
| Annual Income Slab | Tax Rate |
|---|---|
| Up to ₹3,00,000 | Nil |
| ₹3,00,001 to ₹6,00,000 | 5% |
| ₹6,00,001 to ₹9,00,000 | 10% |
| ₹9,00,001 to ₹12,00,000 | 15% |
| ₹12,00,001 to ₹15,00,000 | 20% |
| ₹15,00,001 and above | 30% |
Rebate under Section 87A (New Regime): A full rebate is available for taxpayers with total income up to ₹7,00,000 under the new regime. This means if your taxable income is ₹7,00,000 or less, your tax liability after rebate is ZERO. This is a significant benefit for employees with moderate incomes.
Standard Deduction (New Regime): ₹75,000 (increased from ₹50,000 in earlier years)
Cess: Health and Education Cess at 4% on the total tax amount (applicable in both regimes)
Surcharge: 10% if income exceeds ₹50 lakh; 15% if income exceeds ₹1 crore; 25% if income exceeds ₹2 crore; 37% if income exceeds ₹5 crore (applicable in both regimes)
Old Tax Regime Slabs for FY 2026-27
The old tax regime allows you to claim various deductions and exemptions (Section 80C, 80D, HRA, LTA, home loan interest, etc.) but at higher tax rates. The slab structure is unchanged for FY 2026-27:
| Annual Income Slab | Tax Rate |
|---|---|
| Up to ₹2,50,000 | Nil |
| ₹2,50,001 to ₹5,00,000 | 5% |
| ₹5,00,001 to ₹10,00,000 | 20% |
| ₹10,00,001 and above | 30% |
Rebate under Section 87A (Old Regime): Full rebate for taxpayers with total income up to ₹5,00,000. Tax liability is zero if income ≤ ₹5,00,000.
Standard Deduction (Old Regime): ₹50,000

Real-World Examples: Which Regime Saves More?
Example 1: Employee with ₹6 Lakh CTC (All Deductions)
Rohan works in Kochi with a total salary of ₹6,00,000. His basic salary is ₹2,40,000 (40% of CTC). He pays ₹8,000 per month in rent and has invested ₹50,000 in ELSS.
Old Regime: Gross income ₹6,00,000 − Standard deduction ₹50,000 − HRA exemption ₹41,000 − Section 80C ₹50,000 = Taxable income ₹4,59,000. Tax = ₹10,450 + 4% cess = ₹10,868.
New Regime: Gross income ₹6,00,000 − Standard deduction ₹75,000 = Taxable income ₹5,25,000. Tax = ₹11,250 + 4% cess = ₹11,700.
Verdict: Old regime saves approximately ₹832. Both are close — the old regime wins marginally.
Example 2: Mid-Level Employee with ₹12 Lakh CTC (Maximising Deductions)
Priya works in Thiruvananthapuram with a CTC of ₹12,00,000. Basic salary ₹4,80,000. She pays ₹15,000/month rent, invests ₹1.5 lakh in 80C (PPF + ELSS), has health insurance of ₹25,000 (80D), and contributes ₹50,000 to NPS Tier I (80CCD(1B)).
Old Regime: Gross ₹12,00,000 − Std deduction ₹50,000 − HRA ₹96,000 − 80C ₹1,50,000 − 80D ₹25,000 − 80CCD(1B) ₹50,000 = Taxable ₹8,29,000. Tax = ₹95,800 + 4% cess = ₹99,632.
New Regime: Gross ₹12,00,000 − Std deduction ₹75,000 = Taxable ₹11,25,000. Tax = ₹1,18,125 + 4% cess = ₹1,22,850.
Verdict: Old regime saves ₹23,218. The difference grows with more deductions.
Example 3: Senior Employee with ₹25 Lakh CTC (Maximum Benefit)
Vijay in Kochi earns ₹25,00,000. Basic ₹10,00,000. He pays ₹30,000/month rent, maxes out 80C (₹1.5L in PPF), has family health insurance of ₹50,000 (80D), parents' insurance ₹50,000, contributes ₹50,000 NPS, and has a home loan with ₹2,00,000 annual interest.
Old Regime: Gross ₹25,00,000 − Std deduction ₹50,000 − HRA ₹1,60,000 − 80C ₹1,50,000 − 80D ₹1,00,000 − 80CCD(1B) ₹50,000 − Section 24 ₹2,00,000 = Taxable ₹17,90,000. Tax = ₹3,37,000 + 10% surcharge + 4% cess = ₹3,85,528.
New Regime: Gross ₹25,00,000 − Std deduction ₹75,000 = Taxable ₹24,25,000. Tax = ₹5,26,875 + 10% surcharge + 4% cess = ₹6,02,156.
Verdict: Old regime saves ₹2,16,628 per year. A massive difference.

Based on the examples above and across thousands of salary scenarios, here is a practical decision framework:
Choose the OLD regime if: Your total deductions (80C + 80D + HRA + home loan interest + NPS + other deductions) exceed approximately ₹2,00,000 per year. The higher the deductions, the more beneficial the old regime becomes. This is typically the case for employees with home loans, children's tuition fees, and those making maximum 80C investments.
Choose the NEW regime if: Your total deductions are below ₹2,00,000, OR you prefer simplified tax filing without collecting rent receipts, investment proofs, and insurance premium receipts. The new regime is also usually better for employees with income up to ₹7,00,000 (due to the ₹87A rebate making tax zero) and for those who do not have significant rent, insurance, or investment expenses.
For income between ₹7-15 lakh: This is the grey zone where the regime choice is most sensitive to your specific deductions. Use our CTC to In-Hand Calculator to compute both scenarios with your exact numbers before deciding.
Important: How to Switch Between Tax Regimes
For FY 2026-27, the new tax regime is the default. If you want to opt for the old regime, you must take specific action:
- For salaried employees: Submit Form 10-IEA (or the applicable declaration) to your employer at the beginning of the financial year (typically April-May). This form informs your employer that you wish to opt for the old tax regime, and the employer will compute TDS accordingly based on your investment declarations.
- For ITR filing: When filing your income tax return for FY 2026-27, you will be asked which regime you are opting for. Your choice at the time of ITR filing overrides the choice made with your employer. This means even if your employer deducted TDS under the new regime, you can still opt for the old regime while filing your ITR — and claim the refund for excess TDS deducted.
- One-time flexibility for business income: Taxpayers without business income can switch between regimes every year. For those with business income, the choice is sticky — once you opt out of the new regime, you cannot return to it unless you cease to have business income.
Understanding Marginal Relief
Marginal relief is a provision that prevents a taxpayer from paying more tax than the amount by which their income exceeds the threshold of the slab. It applies primarily in the new regime where the rebate under Section 87A is available only up to ₹7,00,000 income. For example, if your taxable income is ₹7,00,001 (just ₹1 above the rebate limit), without marginal relief, you would pay tax on the entire income — which would be unfairly high compared to someone earning ₹7,00,000 and paying zero tax. Marginal relief ensures that in such cases, the tax payable does not exceed the amount of income that exceeds ₹7,00,000. In this example, the tax would be limited to ₹1 (the excess over ₹7,00,000). The marginal relief calculation is done automatically by the income tax portal when you file your return.
How TDS on Salary Works Under Each Regime
For employers, the choice of tax regime by employees directly impacts TDS computation. Here is how it works in practice:
- Under the new regime (default): The employer computes TDS based on the new regime slab rates. No deduction for 80C, 80D, HRA, LTA, or home loan interest. Standard deduction of ₹75,000 is applied automatically. Investment declarations are not required from the employee.
- Under the old regime (opt-in): The employer computes TDS after allowing eligible deductions based on investment declarations submitted by the employee. The employee must submit proof of investments (typically by December-January) for the employer to verify the declarations. Standard deduction of ₹50,000 is applied.
For payroll teams managing TDS for employees who switch regimes mid-year (which is not permitted — the regime choice for TDS purposes is made at the start of the year), the employer must apply the same regime for the entire financial year. However, the employee can change their choice while filing ITR.

- Decide your regime by April-May: The earlier you decide, the earlier your employer deducts correct TDS. Changing your investment declarations mid-year creates reconciliation challenges.
- Maximise 80C early: Start your ELSS SIP or PPF contributions in April itself rather than rushing in March. Spreading investments across the year is more manageable and avoids year-end cash flow pressure.
- Don't ignore NPS 80CCD(1B): The additional ₹50,000 deduction over 80C is available regardless of your 80C usage. Even a ₹1,000 contribution to NPS qualifies you for this deduction.
- Health insurance for parents: If your parents are senior citizens, you can claim up to ₹50,000 under 80D for their health insurance — a deduction many employees miss.
- Home loan strategy: If you have a home loan, the ₹2,00,000 interest deduction plus principal repayment under 80C makes the old regime almost always beneficial.
- Track HRA properly: Ensure you have rent receipts and landlord PAN (if annual rent > ₹1,00,000) ready before December when most employers ask for proof.
