Why You Should Use an Income Tax Calculator AY 2026-27

The fiscal year FY 2025-26 corresponds to Assessment Year (AY) 2026-27, which means your tax return for income earned between April 1, 2025 and March 31, 2026 will be assessed in the year 2026-27. Using the income tax calculator ay 2026-27 helps you plan your taxes ahead of time and make smart financial decisions — whether you are a salaried employee, a freelancer, or a business owner.

What are the Income Tax Slab Rates for FY 2025-26?

The Government of India revised the income tax structure significantly in Budget 2025. Under the New Tax Regime (Section 115BAC), taxpayers have the option to choose simpler slab rates with fewer deductions, while the old regime still exists but with limited benefits. The key slabs applicable for FY 2025-26 (AY 2026-27) under the new regime are:

Additionally, a 4% Health & Education Cess is added to total tax liability.

In the old tax regime, slabs remain similar to previous years, but taxpayers often find the new regime more beneficial because of higher basic exemption and larger tax slabs.

Rebate u/s 87A: Zero Tax for Lower Incomes

One of the most taxpayer-friendly provisions in the new tax regime is the Rebate u/s 87A. Under this rule, individuals whose net taxable income does not exceed ₹12 lakh are eligible for a full tax rebate of up to ₹60,000, effectively reducing their tax liability to zero.

This rebate makes it possible for many salaried individuals to pay no income tax despite earning a moderate income. It’s important to note that this rebate is calculated after all deductions and standard reductions are applied.

Calculation of Income Tax on Salary

For Income Tax Calculation Salaried Employees, the process usually involves the following steps:

1. Determine Gross Salary: Include basic pay, allowances, bonus, and other income sources.

2. Apply Standard Deduction: A standard deduction of ₹75,000 is available for salaried employees under the new tax regime.

3. Subtract Eligible Deductions: These may include employer contributions to NPS, PF, and any other valid deductions.

4. Compute Net Taxable Income: This is the income on which taxes will be computed.

5. Apply Income Tax Slab Rates: Use the appropriate slab rates for AY 2026-27.

6. Apply Rebate u/s 87A (if eligible): Reduces the tax payable up to ₹60,000.

7. Add Cess & Surcharge: Add health & education cess at 4% and applicable surcharge.

Example for a hypothetical salaried individual:

• Gross Salary: ₹10,75,000

• Standard Deduction: ₹75,000

• Net Taxable Income: ₹10,00,000

• Tax on slabs: Calculate applicable rates

• Rebate u/s 87A: ₹60,000 (if net tax ≤ ₹60,000 )

• Final Tax: Could be ₹0 if rebate fully applies

This simplified process is what most online income tax calculators perform automatically.
