How this is calculated
The comparison
- New regime (s.202, the default): salary − the ₹75,000 standard deduction, taxed at its slabs with its rebate, surcharge and cess. The deductions below are not allowed in it (s.202(2)).
- Old regime (opting out under s.202(4)): salary − the ₹50,000 standard deduction − the exempt part of HRA − home-loan interest − the Chapter VIII deductions, each within its limit, then its own slabs, rebate, surcharge and cess.
- Break-even: the smallest total of deductions and exemptions at which the old regime’s tax is lower than the new regime’s. Each rupee that counts takes a rupee off taxable income.
The limits
- s.123 payments (Schedule XV, such as provident fund and life insurance premiums): up to ₹1,50,000.
- Your own NPS contribution, s.124(3): up to ₹50,000, on top of s.123.
- Health insurance, s.126: up to ₹25,000 for self and family and ₹25,000 for parents; ₹50,000 for a group with a senior citizen in it.
- Interest on a loan for a self-occupied house: up to ₹2,00,000 (s.22(2)), ₹30,000 where its conditions are not met.
Assumptions
- A resident individual, for Tax Year 2026-27 (FY 2026-27): income earned from 1 April 2026 to 31 March 2027.
- Salary is the only income. Professional tax and employer NPS contributions are not included.
- You enter the exempt part of your HRA, not the HRA you receive: work it out with the HRA calculator.
- Health insurance: the higher limit applies to a group when anyone insured in it is a senior citizen (s.126(8)(a)). Choose “Someone 60+” for a senior spouse, say; your own age of 60 or more counts on its own.
- Home-loan interest is for a self-occupied house that meets the conditions for the ₹2,00,000 limit (s.22(2)(a)); otherwise the limit is ₹30,000.
Why can the official calculator show a different figure?
For the old regime, the Income Tax Department’s Advance calculator matched our figures to the rupee in every case we checked, with three exceptions. Just above ₹2 crore of income it charged a 15% surcharge instead of 25% with marginal relief. Above ₹5 crore it charged 25% instead of 37%. And it does not round taxable income to ₹10: taxable income of ₹5,00,001 to ₹5,00,004 rounds down to ₹5,00,000 under the Act (s.516) and gets the full rebate, where the calculator shows tax. We follow the Act.
Which regime applies if I don’t choose?
The new regime (s.202) is the default. To be taxed under the old regime you opt out of it under s.202(4).
