Detailed Breakdown of Income Tax Slab For AY 2025-26

Your final tax liability is determined by applying the prescribed rates to your taxable income. The slabs differ markedly between the two regimes.

New Tax Regime Slabs and Rates

The new regime features seven tax brackets with concessional rates. A key benefit is the enhanced rebate under Section 87A, which reduces tax to zero for individuals with a total income up to ₹12 lakh.

Income Tax Slab (₹)	Income Tax 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%

Old Tax Regime Slabs and Rates

The old regime has three primary slabs for individuals below 60 years, but the ability to claim deductions often lowers the effective taxable income placed into these slabs.

Income Tax Slab (₹)	Income Tax Rate
Up to 2,50,000	Nil
2,50,001 – 5,00,000	5%
5,00,001 – 10,00,000	20%
Above 10,00,000	30%

Note for Senior Citizens: The old regime offers higher exemption limits for resident seniors: ₹3 lakh for those aged 60-80 years, and ₹5 lakh for super seniors above 80 years.

Calculating Your Tax Liability: A Step-by-Step Approach

Accurately determining your tax under the income tax slab for AY 2025-26 for salaried person involves a clear process.

Compute Gross Total Income: Aggregate income from all sources: salary, house property, capital gains, business/profession, and other sources.
Arrive at Taxable Income:
- Under Old Regime: Subtract the standard deduction (₹50,000) and all eligible investments and payments (e.g., under Sections 80C, 80D).
- Under New Regime: Subtract the standard deduction (₹75,000) and the very few allowed deductions.
Apply the Relevant Tax Slabs: Use the tables above to calculate the tax on the taxable income.
Apply Rebate (if eligible): Deduct the rebate under Section 87A if your total income is within the specified limit (₹5 lakh for old, ₹12 lakh for new regime).
Add Surcharge and Cess:
- Surcharge: Applied on the tax amount if income exceeds specified limits. Rates differ between regimes.
- Health and Education Cess: 4% is added to the total of tax and surcharge.

Illustrative Calculation

Consider Neha, with a basic salary of ₹1 lakh/month and other allowances. After accounting for HRA exemption and standard deduction, her gross taxable salary is ₹16.5 lakh under the old regime and nearly ₹20 lakh under the new regime. After claiming deductions of ₹1.7 lakh (80C, 80D, 80TTA) under the old regime, her final tax liability is approximately ₹2.73 lakh. Under the new regime, with no such deductions, her liability is about ₹2.12 lakh. For her, the new regime is more beneficial.

Strategic Tax Planning and Key Considerations

Choosing your path through the income tax slab for AY 2025-26 requires strategic thought.

Regime Selection is Annual: You can switch regimes each year. Analyze your projected income and eligible deductions for FY 2024-25 to decide.
Leverage the Standard Deduction: As a salaried person, remember this deduction is available in both regimes—₹75,000 in the new and ₹50,000 in the old.
Understand the True Benefit of Deductions (Old Regime): The value of a deduction equals your highest marginal tax rate. A ₹1.5 lakh 80C investment saves ₹45,000 for someone in the 30% slab, but only ₹7,500 for someone in the 5% slab.
Plan for Surcharge: High-net-worth individuals must factor in the surcharge, which can significantly increase the effective tax rate. The new regime caps the surcharge on income above ₹5 crore at 25%, compared to 37% in the old regime.
Use Online Calculators: Utilize reliable online income tax calculators to simulate scenarios under both regimes. Input your salary, expected investments, and other incomes to get a precise estimate.

Understanding the intricacies of the income tax slab for AY 2025-26 for salaried person empowers you to fulfill your civic duty while optimizing your finances. By carefully evaluating the old and new regimes in light of your personal financial data, you can ensure compliance and retain more of your hard-earned income.
