India's salary taxation landscape changed materially in FY 2024-25. The new tax regime became the default, slab rates were restructured, and the standard deduction was raised to ₹75,000. For most salaried employees, the question now is not "how do I maximise old regime deductions" but "which regime actually saves me more money?"
Then, within whatever regime you choose, there's a second layer of optimisation: how your CTC is structured determines how much hits your bank account regardless of which regime you're on.
The new tax regime slabs (FY 2025-26)
| Income Slab | Tax Rate | |---|---| | Up to ₹3 lakh | 0% | | ₹3-7 lakh | 5% | | ₹7-10 lakh | 10% | | ₹10-12 lakh | 15% | | ₹12-15 lakh | 20% | | Above ₹15 lakh | 30% |
Plus: 4% health and education cess on the tax amount. Section 87A rebate makes income up to ₹7 lakh effectively tax-free under the new regime.
Standard deduction of ₹75,000 applies automatically. So an employee earning ₹7.75 lakh CTC (gross salary) pays zero tax under the new regime.
Old regime vs new regime: who should switch?
The old regime wins when the sum of your eligible deductions exceeds the structural advantage of the new regime's lower slabs. The crossover point varies by income.
At ₹10 LPA: Old regime typically wins only if you have home loan interest + full 80C + HRA. Without all three, new regime wins.
At ₹15 LPA: Old regime needs home loan interest near the ₹2 lakh limit, full 80C (₹1.5 lakh), NPS 80CCD(1B) (₹50,000), and significant HRA exemption. If you're renting and paying home loan interest, old regime is competitive. Otherwise, new regime is usually better.
At ₹20 LPA+: Old regime can win with a well-structured salary and all deductions maximised, but only if you're actually making the investments (not just "planning to"). If your old-regime advantage exists only on paper because you claim to invest but don't, you lose both the deductions and the lower slab rates.
Info
The cleanest test: calculate your tax liability under both regimes using last year's actual numbers (not projected investments). Most people discover they've been on the "better" regime without checking.

Salary structuring: optimising regardless of regime
Your regime choice affects the tax on your income. But how your CTC is structured affects what gets defined as income in the first place. These are different levers.
HRA optimisation (old regime only)
If you're on the old regime and paying rent, maximising HRA exemption is the biggest single lever. The exemption is the minimum of three values — so you want all three to be as high as possible.
The easiest win: ensure you're actually collecting rent receipts and submitting them to your employer. HRA paid without submitted receipts is fully taxable.
Warning
Landlord PAN is mandatory for rent above ₹1 lakh/year (₹8,333/month). If your landlord refuses, you lose the HRA exemption on that amount. Many urban tenants lose significant tax benefits for lack of a documented PAN number on their rent agreement.

Try with your numbersEmployer NPS contribution (both regimes)
Employer contribution to NPS under Section 80CCD(2) is deductible from income in both the old and new tax regime — up to 10% of basic salary (14% for government employees). This is one of the few real tax benefits that works under the new regime.
If your employer offers a salary restructuring option, converting some special allowance to employer NPS contribution can save meaningful tax — but remember: the NPS corpus is locked until age 60 with mandatory annuity requirements.
At 30% bracket, ₹1 lakh of employer NPS saves ₹31,200 in tax (₹30,000 tax + ₹1,200 cess). That's a significant benefit, but only if you're comfortable with long-term NPS illiquidity.
LTA (Leave Travel Allowance)
LTA is exempt from tax (old regime) for travel within India for self and family, twice in a block of four calendar years. If your CTC includes LTA and you travel domestically, claim it — bring boarding passes, hotel receipts, cab booking receipts. The exemption limit equals the actual LTA component in your salary.
Under the new regime, LTA is fully taxable. If you move to the new regime, LTA in your salary structure is just taxable income.
Meal vouchers and food coupons
Employer-provided meal vouchers (Sodexo, Zeta, etc.) up to ₹2,200/month are exempt from tax under the old regime. Small benefit, but worth optimising.
Keeping your structure simple
The complexity of multi-component CTC structures is real. Many employees forget to submit proofs, miss exemptions, and then face TDS shortfalls at year-end. A simpler salary structure with fewer components is worth slightly less optimisation if you know you won't follow through on the documentation.
The mistake most salaried employees make
They optimise for annual tax saving and ignore the cash flow impact. An HRA exemption that requires paying ₹30,000/month rent doesn't save money if you're paying for a flat you don't need, just to claim the deduction. A Section 80C investment of ₹1.5 lakh in a 3-year FD locks up liquidity you might need.
The right sequence:
- Run the actual regime comparison using your real numbers
- Pick the regime that saves more tax given investments you are actually making (not hypothetical ones)
- Optimise salary structure within that regime
- Review once a year — regime choice can change as your income and obligations shift
