Income tax old vs new regime: practical salary examples
This guide is educational and simplified. Final tax depends on your salary structure, deductions, surcharge, and current law.
Example 1: minimal deductions
For a salaried person with limited deductions, new regime often wins due to lower slab rates. Use the calculator with your taxable income and compare side by side.
Example 2: high deductions
If you claim HRA, 80C, 80D, and home-loan benefits, old regime can become competitive or better depending on total deductions.

Scenario matrix (FY 2026 planning)
| Salary profile | Deduction depth | Likely better starting point | What to test next |
|---|---|---|---|
| Single income, low exemptions | Limited 80C/80D, no rent claim | New regime | Run one old-regime case with realistic deductions, not assumptions. |
| Rent-paying salaried employee | Meaningful HRA + 80C + 80D | Old regime can compete | Validate HRA exemption first, then compare net tax gap. |
| Home-loan + family cover case | 24(b) + 80C + 80D + NPS | Old regime often stronger | Stress test if deductions fall in future years. |
Decision framework
- Start with new regime as baseline (default payroll path).
- Add actual old-regime deductions only if documentation is strong.
- Compare annual tax gap and monthly cash-flow impact, not slab headline alone.
- Review again if salary mix, rent, or home-loan status changes during the year.
