Every year around tax-planning time, the same question comes up: should you stick with the old tax regime and its deductions, or go with the new regime’s lower rates but fewer exemptions? For FY 2026-27 (AY 2027-28), the Union Budget 2026 kept the slab rates and rebate limits unchanged from the previous year, so the comparison stays largely the same as it was for FY 2025-26 — but it’s still worth re-checking your own numbers each year, especially if your income or investments have changed.
Here’s a clear breakdown of both regimes and a simple way to decide which one fits you.
Quick Background: Why Two Regimes Exist
The new tax regime (under Section 115BAC) is the default regime for individuals, HUFs, and similar taxpayers, unless you actively choose to opt out. It offers lower tax rates spread across more slabs, but removes most of the deductions and exemptions available under the older system. The old tax regime is still available as an opt-in choice, and it keeps the traditional deductions — Section 80C, HRA, home loan interest, and others — but at higher slab rates.
If you don’t explicitly choose, you’re taxed under the new regime by default. Salaried employees need to inform their employer of their choice so the correct TDS gets deducted from their salary through the year; if you’re filing your own return for business or professional income, the choice involves a specific form and has more limited flexibility to switch year to year.
New Tax Regime Slabs for FY 2026-27
- Up to ₹4 lakh: Nil
- ₹4 lakh to ₹8 lakh: 5%
- ₹8 lakh to ₹12 lakh: 10%
- ₹12 lakh to ₹16 lakh: 15%
- ₹16 lakh to ₹20 lakh: 20%
- ₹20 lakh to ₹24 lakh: 25%
- Above ₹24 lakh: 30%
A standard deduction of ₹75,000 applies for salaried individuals and pensioners under the new regime. A rebate under Section 87A of up to ₹60,000 effectively makes taxable income up to ₹12 lakh tax-free, which for salaried individuals (after the standard deduction) extends the effective tax-free threshold to around ₹12.75 lakh of gross salary. Above this threshold, marginal relief provisions soften the jump so you’re not suddenly worse off than someone earning just under the limit.
Old Tax Regime Slabs for FY 2026-27
- Up to ₹2.5 lakh: Nil
- ₹2.5 lakh to ₹5 lakh: 5%
- ₹5 lakh to ₹10 lakh: 20%
- Above ₹10 lakh: 30%
Under the old regime, the Section 87A rebate applies only up to ₹5 lakh of taxable income, capped at ₹12,500 — a much lower threshold than the new regime’s ₹12 lakh.
What You Lose and Keep Under Each Regime
Under the new regime, most of the familiar deductions aren’t available — no Section 80C (PPF, ELSS, life insurance premiums, etc.), no HRA exemption, no home loan interest deduction on a self-occupied property under Section 24(b) for most cases, and no standard Chapter VI-A deductions like 80D for health insurance. A small number of deductions, such as the employer’s NPS contribution under Section 80CCD(2), remain available even under the new regime.
Under the old regime, you keep access to the full range of deductions — Section 80C investments, HRA if you pay rent, home loan interest, health insurance premiums under 80D, and others — but you’re taxed at the higher slab rates shown above.
How to Actually Decide
The honest answer is: it depends on how much you can genuinely claim in deductions, not just what’s theoretically available. A rough way to think about it:
- Add up what you’d actually claim under the old regime — Section 80C investments you’re already making, HRA if applicable, home loan interest, 80D premiums, and anything else relevant to you
- If that total is small (a few common cases: minimal investments, no home loan, no HRA claim), the new regime’s lower rates usually win
- If your deductions are substantial — especially a combination of home loan interest, full 80C utilization, and HRA — the old regime can still come out ahead, particularly at certain income levels
- Run the numbers both ways using a tax calculator (the Income Tax Department’s official site offers one) before deciding, rather than relying on a general rule of thumb, since the exact crossover point depends on your specific income and deduction amounts
This article gives you the factual structure to compare both regimes, but it isn’t personalized tax advice — for your specific situation, especially if your income mix is complex, it’s worth confirming the better choice with a chartered accountant or tax advisor before filing.
Switching Between Regimes
If you’re a salaried individual with no business or professional income, you can generally choose between the old and new regime afresh each financial year when filing your return. If you have income from business or profession, switching back to the new regime after opting for the old regime is more restricted — typically allowed only once in your lifetime — so that choice deserves more careful thought.
Common Mistakes to Avoid
- Assuming the new regime is automatically better just because it’s the default, without actually comparing your numbers
- Forgetting to inform your employer of your regime choice for the year, leading to TDS being deducted based on the wrong assumption
- Not accounting for the standard deduction and 87A rebate correctly when comparing the two regimes, which can make the new regime look worse than it actually is
- Ignoring marginal relief calculations near the ₹12 lakh and ₹12.75 lakh thresholds, where the actual tax impact of crossing the line is smaller than a naive slab calculation suggests
- Treating last year’s decision as automatically correct this year, without checking whether your income or deductions have changed enough to flip the better choice
FAQs
Is the new tax regime compulsory now? No, it’s the default if you don’t choose otherwise, but you can opt for the old regime each year (with more restrictions if you have business or professional income).
Did Budget 2026 change the tax slabs for FY 2026-27? No. The Union Budget 2026 retained the same slab rates, rebate limits, and standard deduction as the previous year for both regimes.
Can senior citizens get a higher exemption limit under the new regime? No, the new regime applies the same slabs to all individual taxpayers regardless of age. The old regime continues to offer age-based benefits, including a higher basic exemption limit for senior and super senior citizens.
Which deductions are still available under the new regime? Very few — notably the standard deduction for salaried individuals and pensioners, and the employer’s contribution to NPS under Section 80CCD(2). Most other common deductions (80C, HRA, home loan interest on self-occupied property, 80D) are not available under the new regime.
Can I switch regimes every year if I only have salary income? Yes, salaried individuals without business or professional income can generally choose between the two regimes afresh each year at the time of filing their return.
