EZTax question pages connect the calculation method with the relevant calculator or tax-tool workflow.
Quick Answer
For AY 2026-27, calculate tax using the Income-tax Act, 1961 and the tax regime applicable to that assessment year. Enter the correct income, eligible deductions/exemptions, tax already paid and applicable rebate or surcharge inputs rather than relying on a simple salary-only calculation.
How Is the Calculation Done?
Add taxable income under the relevant heads, apply eligible exemptions/deductions, determine taxable income, apply the applicable slabs or special rates, then account for rebate, surcharge, cess, TDS, advance tax and other credits as relevant.
What Inputs Should You Check?
- Applicable tax year or assessment year and the governing tax law.
- Taxpayer category, age and residential status where relevant.
- Income or transaction amounts from reliable source records.
- Eligible deductions, exemptions, losses, credits and withholding already paid.
- Special-rate income or transaction-specific rules, if any.
Simple Example
Example: A salary figure on a payslip is not necessarily the same as taxable income. Standard deduction and other applicable components must be considered before the final tax is calculated.
Which Tax Law and Tax Year Should Be Used?
For AY 2026-27 and earlier assessment years, calculations generally relate to the Income-tax Act, 1961. For Tax Year (TY) 2026-27 onward, the Income-tax Act, 2025 applies. The Income Tax Department calculator now supports selecting the applicable Act and, for the new Act, Tax Year 2026-27. Do not mix an old-Act assessment year with a new-Act tax-year calculation.

For this calculation, start with Income Tax Calculator (Old vs New). The question page explains the inputs and logic; the calculator or tool is where you should enter your actual figures.
Common Mistakes
- Using the wrong tax year or mixing AY and TY terminology.
- Using gross receipts or salary as taxable income without considering the applicable computation rules.
- Applying a deduction or exemption without checking whether it is available under the selected regime.
- Ignoring special tax rates, surcharge, cess or tax credits.
- Relying on AIS/TDS data as the only source instead of reconciling all relevant records.
Why a Calculator Is Useful
A calculator makes assumptions visible and reduces arithmetic errors, but it does not replace checking the legal classification of the income or transaction. For complex cases, compare the result with Form 16, AIS, Form 26AS, broker statements, books, challans or other source documents.
