The default regime is age-neutral: nil up to ₹4 lakh, then progressive 5%, 10%, 15%, 20%, 25% and 30% bands. In the optional old-style regime, a resident aged 60–79 has a ₹3 lakh basic exemption.
Tax Year 2026–27 is governed by the Income-tax Act, 2025. Rebate, standard deduction for pension, section 153 deposit-interest deduction, medical deductions and advance-tax relief must be tested separately. Non-residents do not receive age-based old-regime slabs.
Confirm age and residence; separate pension, interest, house property and special-rate income; compute both regimes; apply eligible deductions, rebate, surcharge, marginal relief and cess; subtract TDS/advance tax.
A resident aged 67 has pension ₹10 lakh and bank interest ₹1 lakh. Compare default-regime tax after the applicable standard deduction with optional-regime tax after pension deduction, deposit-interest deduction and other eligible claims.
The example is an illustration, not a substitute for the taxpayer's facts. A change in status, period, payment mode, document, city, asset, relationship or scheme can change the result.
Search pages often state a rate or limit without identifying the governing base. The calculation must distinguish gross receipt from taxable profit, tax from TDS, a deduction from an exemption, salary from business income, and an accounting entry from the tax treatment.
| Decision point | Required treatment |
|---|---|
| Legal year | Use the Act, rules and notification effective for the income or transaction period |
| Taxpayer category | Confirm residence, age, entity, employee/business status and regime |
| Calculation base | Use the statutory definition rather than CTC, net bank receipt or accounting label |
| Ceiling or rate | Apply actual-amount, percentage, shared, lifetime and gross-income limits in sequence |
| Documentation | Link every input to an invoice, statement, contract, certificate or official record |
| Final output | Show tax, surcharge, cess, interest and TDS/TCS credits separately |
