Income Tax Calculator India FY 2026-27

How to Use Income Tax Calculator India FY 2026-27

Start by entering your gross annual salary rather than your cost to company. Gross salary normally includes basic salary, taxable allowances, bonuses and other taxable cash compensation before employee deductions. Employer provident-fund contributions included in CTC should not automatically be counted as gross salary.

Add your other ordinary taxable income, such as bank interest. Select the relevant tax regime and age category. The age category affects old-regime basic exemption limits, while the new-regime slabs used here do not change with age.

Enter eligible deductions and exemptions carefully. Under the old regime, common deductions include qualifying Section 80C investments and certain medical-insurance premiums. Under the new regime, most familiar exemptions and deductions are unavailable, although specified deductions remain permitted.

Run the Income Tax Calculator India FY 2026-27 to review the slab tax, rebate, surcharge, cess and remaining balance. Compare the two regime estimates before making a tax-planning decision.

When your employer has already deducted tax, enter the total in the additional adjustments panel. The calculator then displays the estimated balance after those payments. A negative balance is shown as a potential excess payment, not a guaranteed refund.

Old vs New Tax Regime for FY 2026-27

The new tax regime is the default framework for eligible individuals. It offers revised progressive slabs and a higher salary standard deduction, but generally restricts familiar tax-saving deductions. The old regime retains different slab rates and allows qualifying deductions and exemptions.

The Income Tax Calculator India FY 2026-27 displays both estimated liabilities so you can compare the financial impact. A lower slab rate does not always mean a lower final liability, particularly when significant old-regime deductions are available.

When might the new regime be better?

The new regime can be attractive for employees who have relatively few eligible deductions. Its ₹75,000 standard deduction for salary income and the resident-individual Section 87A rebate can reduce liability substantially at qualifying income levels.

When might the old regime be better?

The old regime may be competitive when an employee can legitimately claim substantial HRA exemption, Section 80C deductions, eligible health-insurance deductions or other permitted reliefs. The amount of tax saved depends on income, age and actual eligibility.

Compare the results using the tax regime savings comparison calculator. Remember that the choice available to taxpayers with business or professional income can be subject to additional procedural restrictions.

Standard Deduction, HRA and Tax-Saving Investments

Taxable income is often lower than gross salary. The difference comes from permitted deductions, qualifying exemptions and other statutory adjustments. However, the availability of each benefit depends on the tax regime and the individual's circumstances.

Standard deduction for salaried taxpayers

For the illustrated tax rules, the salary standard deduction is ₹75,000 under the new regime and ₹50,000 under the old regime. The deduction is applied to eligible salary income, not separately to every source of income.

Section 80C and other old-regime deductions

Eligible Section 80C contributions and investments can include employee provident-fund contributions, qualifying life-insurance premiums, PPF contributions and certain other payments. The combined Section 80C limit is generally ₹1.5 lakh, subject to applicable conditions.

Additional deductions may be available for qualifying medical insurance, certain NPS contributions and other permitted expenses. Each provision has its own limits and conditions. Do not enter amounts simply because they were paid; confirm that they qualify.

House Rent Allowance exemption

HRA exemption under the old regime generally depends on actual HRA received, eligible salary, rent paid and the prescribed city category. The calculation uses the least of the relevant statutory amounts. The exemption is generally unavailable under the new regime.

Use the HRA calculator to estimate qualifying exemption before entering it into the Income Tax Calculator India FY 2026-27. Avoid deducting the same amount twice.

Section 87A Rebate and Marginal Relief

Section 87A can reduce the income tax of eligible resident individuals. Under the new-regime framework used here, ordinary taxable income up to ₹12 lakh can qualify for a rebate of up to ₹60,000, subject to the statutory conditions.

The rebate threshold concerns taxable income, not annual CTC or gross salary. A salaried individual with ₹12.75 lakh of eligible gross salary and only the ₹75,000 standard deduction can have ₹12 lakh of taxable income before other adjustments.

For ordinary taxable income slightly above ₹12 lakh, marginal relief can limit the immediate increase in tax. The relief is not a blanket exemption for all income above that threshold. Special-rate income may be treated differently.

Under the old regime, eligible resident individuals with taxable income not exceeding ₹5 lakh may receive a rebate of up to ₹12,500. Consult the Section 87A rebate calculator for additional examples.

The Income Tax Calculator India FY 2026-27 applies these rebate principles to ordinary income. If you have capital gains, lottery winnings or another category taxed at special rates, use an appropriate detailed tax computation.

Common Income Tax Calculation Mistakes

One frequent mistake is applying a single tax rate to all earnings. Progressive tax slabs work differently: each portion of taxable income is charged at the rate assigned to that band. Another mistake is treating CTC as taxable salary without separating employer costs.

Employees sometimes claim deductions under the wrong regime or assume that all investment contributions are deductible. Tax benefits depend on the specific provision, the chosen regime and the applicable limit. A payment being financially useful does not automatically make it tax-deductible.

Another source of confusion is monthly TDS. Payroll withholding can change after bonus payments, investment declarations, previous-employer income or adjustments made during the financial year. The monthly figure in this calculator is an annual tax equivalent divided by twelve, not a payroll withholding schedule.

Finally, remember that surcharge, special-rate income and complex reliefs can change final liability. The Income Tax Calculator India FY 2026-27 is most suitable for straightforward salary and ordinary-income estimates rather than complex tax returns.

Check the final calculation against your Form 16, Annual Information Statement and other tax records. Official guidance from the Income Tax Department should take priority when rules or individual circumstances require more detailed treatment.
