Old vs New Tax Regime for AY 2026–27: A Practical Comparison

The old-versus-new tax-regime choice cannot be answered from salary alone. It depends on the relevant assessment year, the deductions/exemptions you can legitimately claim, the type of income you have and whether special-rate income is involved.

AY 2026–27: the key new-regime slabs

For Assessment Year 2026–27, the Income Tax Department lists the new-regime slabs as:

The department also states that, for eligible resident individuals, the section 87A rebate in the new regime can be up to ₹60,000 where total income does not exceed ₹12 lakh, subject to the applicable rules. Special-rate income and individual circumstances can affect the calculation.

Why the old regime can still matter

The old regime retains a different rate structure and access to deductions/exemptions that may be valuable for some taxpayers. A person with substantial eligible deductions may get a different result from someone with the same gross salary and almost none.

How to compare correctly

1. Use the correct assessment year.
2. List each income source, not only salary.
3. Separate deductions/exemptions that are genuinely available in each regime.
4. Use the Income Tax Department calculator or filing portal rather than a viral comparison graphic.
5. If you have business/professional income, capital gains, VDA income or complex deductions, check the rules that apply to switching regimes and consider qualified tax advice.

Common mistake: comparing gross salary with taxable income

Rebates and slabs generally operate on taxable/total income concepts defined by tax law, not simply the number in an offer letter. Standard deductions, exemptions, special-rate income and other items can change the result.
