This is the most common question our team at PGT & Associates gets during the ITR season: 'Which regime should I choose?' The honest answer is: it depends. But after doing this analysis for hundreds of clients, we have a very clear framework that gives you the answer in minutes.
The Two Regimes — Quick Summary
Old Regime: Higher tax rates but allows all deductions — 80C (₹1.5L), 80D (health insurance), HRA, LTA, NPS, home loan interest, standard deduction (₹75,000), and many more. Suits people with high deductions.
New Regime (Default from FY 2023-24): Lower tax rates, zero deductions (except standard deduction of ₹75,000 for salaried). Simple, no investment proof required. Suits people with low deductions or high income.
New Regime Tax Slabs FY 2025-26
Up to ₹3 lakh: NIL
₹3 lakh – ₹7 lakh: 5% (effective NIL due to rebate under Section 87A for total income up to ₹7 lakh)
₹7 lakh – ₹10 lakh: 10%
₹10 lakh – ₹12 lakh: 15%
₹12 lakh – ₹15 lakh: 20%
Above ₹15 lakh: 30%
Key benefit: Under the new regime, total income up to ₹12 lakh (₹12.75 lakh for salaried after ₹75,000 standard deduction) is effectively tax-free due to the Section 87A rebate announced in Budget 2025.
Old Regime Tax Slabs FY 2025-26
Up to ₹2.5 lakh: NIL
₹2.5 lakh – ₹5 lakh: 5% (NIL due to rebate up to ₹5 lakh income)
₹5 lakh – ₹10 lakh: 20%
Above ₹10 lakh: 30%
The Breakeven Deduction Analysis
The new regime wins purely on rate for most income levels. The old regime only wins if your deductions are large enough to bring your taxable income below the new regime equivalent. Here is the breakeven for salaried individuals:
Income ₹10 lakh: You need deductions of at least ₹2.5 lakh (beyond standard deduction) for old regime to win. If you have 80C (₹1.5L) + 80D (₹25K) + HRA (₹50K+), old regime typically wins.
Income ₹12 lakh: New regime gives ₹0 tax (with rebate). Old regime gives tax even with maximum deductions. New regime clearly wins.
Income ₹15 lakh: Need deductions of ₹3.75 lakh+ for old regime to match new regime. Possible if you have home loan interest (₹2L under 80EE/24b) + 80C + 80D + NPS.
Income ₹20 lakh+: Old regime wins only if you have very large deductions — typically home loan interest, HRA in metro, NPS, full 80C, 80D family floater. Do the calculation each year.
Deductions That Work Only in Old Regime
Section 80C (₹1.5 lakh): ELSS, PPF, LIC, NSC, ULIP, tuition fees, EPF contribution, home loan principal repayment.
Section 80D: Health insurance premium — ₹25,000 for self/family, ₹25,000 additional for parents (₹50,000 if parents are senior citizens).
HRA exemption: House Rent Allowance — actual HRA received, 50% of basic (metro) or 40% (non-metro), actual rent minus 10% of basic — lowest of the three is exempt.
Home loan interest (Section 24b): Up to ₹2 lakh per year on self-occupied property.
NPS contribution (Section 80CCD(1B)): Additional ₹50,000 over and above 80C limit.
LTA: Leave Travel Allowance — actual travel cost for two journeys in a 4-year block period.
Standard deduction: ₹75,000 for salaried — this IS available in new regime too now.
Who Should Choose the New Regime?
Salaried with income up to ₹12.75 lakh: Zero tax under new regime — don't bother with old.
Salaried with few deductions: If you don't have a home loan and live in your own house, old regime offers little benefit.
Business income earners: New regime offers lower compliance burden — no need to track deductions.
Young professionals just starting: New regime simplifies filing significantly.
Who Should Choose the Old Regime?
Home loan borrowers in metros: Interest deduction of ₹2 lakh + principal in 80C + HRA together can make old regime significantly better.
High earners above ₹20 lakh with large investments: Full 80C + 80D family + NPS + home loan can add up to ₹5-6 lakh in deductions.
Those with high HRA: Metro-based employees paying ₹30,000+ monthly rent can exempt significant amounts under old regime.
Senior citizens: Higher basic exemption (₹3 lakh), 80D limit (₹50,000), and 80TTB (₹50,000 interest income) make old regime beneficial.
Can You Switch Between Regimes?
Salaried employees: Can switch every year at the time of filing ITR. Your employer defaults to new regime unless you submit a declaration choosing old.
Business income earners: Can switch only once. If you opt out of new regime, you cannot re-enter for the next 5 years (similar to Section 44AD).
