A common conversation in any Indian office around February or March goes something like this: someone on the team has just heard the new tax regime has lower slabs and wonders aloud whether they should switch. Someone else, who has been claiming HRA and 80C since they started working, says they always pay less under the old regime. A third person hasn't checked in two years and isn't sure which one they are currently on.
All three of them are correct in their own way. The two regimes are genuinely different products, and which one is cheaper depends almost entirely on the deductions a salaried earner is actually claiming, not the ones they could theoretically claim.
This guide unpacks both regimes, the deductions that matter for most salaried employees, and how to compare them without getting lost in the small print. The India Income Tax Calculator can run the comparison for a specific salary; the rest is understanding what the calculator is doing.
Two regimes, one income
For salaried individuals, India currently offers a choice each year:
- The old regime, which has higher slab rates but allows a wide range of deductions and exemptions: HRA, LTA, Section 80C, Section 80D, home loan interest under Section 24, NPS additions under Section 80CCD(1B), and others.
- The new regime, with lower slab rates but a much shorter list of deductions allowed. A standard deduction for salaried employees is permitted under both regimes (with the new regime's standard deduction enhanced in recent budgets), employer NPS contributions under 80CCD(2) are allowed, and a few smaller items, but most of the familiar exemption list does not apply.
The new regime is now the default for most individual taxpayers, meaning if you don't actively opt out, your employer and the income tax portal will calculate your tax under the new regime. Salaried individuals can switch between the two regimes each financial year when filing their return; some other categories (notably business owners with non-speculative business income) face restrictions on flipping back once they opt out.
The slab structures, at a glance
Exact thresholds and rates change with most Finance Acts. The shape has been:
The old regime uses a higher tax-free basic exemption for individual senior citizens and super senior citizens, and a progressively rising set of slabs at rates such as nil, 5%, 20%, and 30%, with surcharges at higher incomes plus a 4% cess on the tax payable.
The new regime uses a longer, flatter band structure with more slabs and lower rates inside each; for example, nil up to a basic threshold, then 5%, 10%, 15%, 20%, and 30% across higher bands, again with surcharges and cess at top incomes. Recent budgets also introduced a rebate (under Section 87A) that effectively makes income up to a defined threshold tax-free for resident individuals opting into the new regime.
For exact figures, the Income Tax Department portal publishes the current year's slabs. The point for planning is that the slabs alone don't decide the cheaper regime; deductions do.
Why lower slab rates don't automatically win
A salaried employee with a typical "tax-planned" salary structure, with HRA used in a metro city, an employer-administered EPF, an LIC or PPF contribution under 80C, health insurance under 80D, and a home loan with interest under Section 24, can build up a substantial tax shield under the old regime.
Take an illustrative example. Riya earns ₹14,00,000 a year as a salaried employee in Bengaluru. Her structure includes:
- HRA, of which approximately ₹1,80,000 is exempt under the standard HRA formula
- EPF: employee contribution of ₹86,400 (12% of basic, where basic is ₹60,000/month)
- Other 80C investments and instruments totalling ₹64,000, bringing total 80C usage to ₹1,50,000 (the cap)
- Section 80D health insurance premium: ₹25,000
- Standard deduction: ₹50,000 (old regime)
Her taxable income under the old regime is roughly ₹14,00,000 − ₹1,80,000 − ₹1,50,000 − ₹25,000 − ₹50,000 ≈ ₹9,95,000. Apply the old regime slabs and the tax (before cess) lands at a particular number.
Under the new regime, those exemptions don't apply. Her taxable income would essentially be ₹14,00,000 minus the new regime's standard deduction. The lower slabs partly offset the lost deductions, but in her situation, the old regime usually still wins because she was already claiming meaningful exemptions.
Contrast that with Arjun, who earns the same ₹14,00,000 but rents from a relative without a formal arrangement (so HRA exemption is awkward), has no home loan, has no health insurance, and contributes only the employer-administered EPF without additional 80C investments. His old-regime deductions are thin. The new regime's lower slabs may produce a smaller bill simply because there wasn't much shielded income to lose.
The slab rates are the easy part. The hard part is being honest about which deductions you'd actually claim.
What the new regime does still allow
It's a shorter list, but it isn't zero. Common items still available under the new regime include:
- The salaried standard deduction (currently enhanced compared to its old-regime counterpart in recent budgets)
- Employer NPS contributions under Section 80CCD(2), within limits
- The Section 87A rebate that, in recent years, has made income below a defined threshold effectively tax-free for resident individuals on the new regime
- Family pension deduction for eligible pensioners
- Certain transport allowances for specified disabilities
- Agniveer Corpus Fund contributions, where applicable
- Exemptions on retirement-related receipts (gratuity within statutory limits, leave encashment within limits, EPF maturity if conditions are met); these are exemptions on receipt, not annual deductions, but they continue under the new regime
What's largely not allowed under the new regime: Section 80C, Section 80D, HRA exemption, LTA exemption, Section 24 home loan interest on self-occupied property, Section 80CCD(1B) NPS, education loan interest under 80E, and most of the long-form deduction list familiar to old-regime planners.
Salary structure shapes the result
For most salaried employees, the comparison between regimes isn't just slabs versus deductions; it's also about how the CTC is structured.
A salary heavy in basic pay drives higher EPF contributions, which feed long-term savings but can affect immediate cash. A salary heavy in HRA is more valuable in cities and to employees in formal rentals than to those staying with family. A salary with special allowance, the catch-all bucket, gives flexibility but no automatic tax shield.
The Salary Calculator is helpful for converting between CTC and in-hand pay assumptions before tax. The EPF Calculator is useful for seeing how much of the basic-pay-driven contribution accumulates over a career, which matters when comparing total compensation rather than annual cash. Long-term benefits like EPF and gratuity often don't show up in the regime comparison but quietly shift the value of a salary structure.
Worked comparison: a salaried earner at ₹18,00,000
Consider a salaried employee earning ₹18,00,000 a year. Three scenarios show how the regime choice shifts:
Scenario A: Heavy old-regime claimant. HRA exemption ₹2,40,000, full 80C ₹1,50,000, 80D ₹50,000, home loan interest ₹2,00,000 (Section 24, self-occupied), standard deduction ₹50,000. Total deductions ≈ ₹6,90,000. Taxable income under the old regime ≈ ₹11,10,000.
Scenario B: Moderate claimant. HRA exemption ₹1,80,000, 80C ₹1,50,000, 80D ₹25,000, no home loan, standard deduction ₹50,000. Total deductions ≈ ₹4,05,000. Taxable income under the old regime ≈ ₹13,95,000.
Scenario C: Minimal old-regime claimant. No HRA exemption, no 80C investments beyond mandatory EPF (which itself does count under 80C up to its share of ₹1,50,000), no 80D, no home loan, standard deduction ₹50,000. Total deductions ≈ ₹50,000–₹1,00,000. Taxable income under the old regime ≈ ₹17,00,000–₹17,50,000.
Under the new regime, the same employee in all three scenarios has taxable income of roughly ₹17,25,000–₹17,50,000 after the new-regime standard deduction (the exact figure depends on the standard deduction enhancement for the year).
In Scenario A, the old regime usually wins by a meaningful margin because deductions of nearly seven lakhs are doing serious work. In Scenario B, the comparison is closer; depending on the exact year's slabs, either regime can come out slightly ahead. In Scenario C, the new regime usually wins because the lower slab rates apply to a higher taxable base, but the base is the same as the old regime, so the lower rates take a smaller bite.
Running the same inputs through the India Income Tax Calculator gives the actual numbers for the current year. The point of working through the scenarios is structural: it's never the regime that "wins". It's the regime that fits your deduction reality.
EPF, gratuity, and the long view
EPF and gratuity sit slightly outside the regime question, but they shape how an employee evaluates total compensation.
EPF contributions are mandatory for most covered employees and produce a long-term, tax-favoured corpus. The employee contribution counts within Section 80C under the old regime; the employer contribution doesn't reduce taxable income but builds the corpus. EPF maturity is exempt from tax if specific conditions on length of service and continuous contribution are met. A 25-year career with steady EPF can produce a final corpus that dwarfs the annual tax savings under either regime.
Gratuity, payable on completion of qualifying service (typically five years), is exempt from tax up to defined statutory limits. For most career-track employees, gratuity is significant cash on the way out of long-tenure jobs. Both regimes preserve this exemption.
That long view is worth keeping in mind when the regime comparison feels close. A few thousand rupees of annual tax difference is small compared with the compounding benefit of EPF and gratuity over a working life.
Common mistakes
Choosing the regime based only on slab rates. Lower rates don't help if you were already claiming substantial exemptions.
Forgetting the cess and surcharge. Slab rates aren't the final answer. Cess (currently 4% on the tax) and surcharges at higher incomes change the comparison.
Assuming HRA exemption "always works." HRA exemption depends on rent paid, basic salary, and metro vs non-metro classification. If rent is informal or to a family member without proper documentation, the exemption can be disallowed during scrutiny.
Forgetting Section 80CCD(1B). The additional ₹50,000 for NPS under 80CCD(1B) is one of the few deductions that adds to the 80C ₹1,50,000 cap rather than being inside it. Under the old regime, this can swing the comparison meaningfully.
Switching regimes mid-financial-year for an employer payroll declaration but forgetting the return. The final regime choice is made when you file the return. If you under-declared deductions in payroll and overpaid, the refund comes through filing.
Practical scenarios
A first-job salaried employee at ₹6,00,000 with no investments and rented accommodation often finds the new regime simpler and competitive on tax. Even if HRA could be claimed, the rebate under Section 87A in the new regime often makes the comparison tilt toward the simpler choice.
A mid-career professional at ₹22,00,000 with a home loan, two children's school fees, life insurance, ELSS, and health insurance for parents typically still benefits from the old regime, because the deduction list is doing five-figure work each year.
A senior employee at ₹40,00,000 with significant 80C usage, NPS additional contribution under 80CCD(1B), home loan interest under Section 24, and a large 80D deduction may find the old regime cheaper, but the gap narrows as the surcharge structure at higher incomes affects both regimes. At very high incomes, the surcharge cap on the new regime can flip the answer.
FAQs
Is the new regime always better for salaried employees? No. It's better for employees who don't have meaningful deductions to claim. Employees making full use of HRA, 80C, 80D, NPS, and home loan interest often still pay less under the old regime.
Does the new regime allow any deductions at all? A short list remains: the standard deduction, employer NPS under 80CCD(2), Section 87A rebate up to a threshold, certain transport allowances for specified disabilities, family pension deduction, and the standard retirement exemptions. Most of the long-form deduction list is unavailable.
Can I switch between old and new regimes every year? Salaried individuals generally can. People with non-speculative business income face restrictions on switching back once they opt out of one regime.
How does my EPF contribution interact with the tax regime? The employee EPF contribution counts under Section 80C under the old regime (subject to the ₹1,50,000 cap shared with other 80C items). It doesn't reduce taxable income under the new regime. EPF maturity is exempt from tax under either regime when statutory conditions are met.
Is gratuity taxable on receipt? Gratuity is exempt up to defined statutory limits for eligible employees. Amounts above the exemption ceiling are taxable in the year of receipt, under whichever regime you're filing.
Where does HRA fit into the comparison? HRA exemption is one of the larger old-regime advantages for renters in metro cities. It doesn't apply under the new regime, which is one of the reasons a renting metro employee with formal rent agreements often still benefits from the old regime.
