Old vs new tax regime in India — which one should you choose?
The new tax regime is now the default, with lower slab rates but no deductions for 80C investments, HRA, or home loan interest (with limited exceptions). The old regime retains these deductions at higher slab rates. As a rule of thumb, taxpayers who claim significant deductions — a large 80C investment, HRA, and home loan interest — often still come out ahead under the old regime, while those with few deductions typically benefit from the new one.
What the new regime offers
The new tax regime applies lower slab rates across income bands and is now the default option unless you explicitly opt for the old regime. It does not allow most common deductions — no Section 80C (PPF, ELSS, life insurance), no HRA exemption, and no home loan interest deduction on a self-occupied property — though it retains the standard deduction for salaried taxpayers and a few other specific exemptions.
What the old regime offers
The old regime taxes income at higher slab rates but allows the full range of deductions: Section 80C (up to Rs 1.5 lakh for PPF, ELSS, insurance premiums, etc.), Section 80D (health insurance premiums), HRA exemption for those paying rent, and home loan interest deduction under Section 24(b). For taxpayers who genuinely use these deductions, the old regime can still result in lower total tax despite the higher rates.

Talk to a CA →How to actually compare the two
The only reliable way to choose is to compute tax liability under both regimes using your actual income and actual deduction claims — not a generic rule of thumb. The income tax portal's e-filing utility computes both automatically, letting you compare before final submission. A rough guide: total deductions above roughly Rs 3.5–4 lakh (varying by income level) tend to tip the balance toward the old regime, but this threshold shifts depending on your specific income slab.
Switching between regimes year to year
Salaried individuals without business income can switch between the old and new regime every year when filing their return — there's no lock-in. Those with business or professional income face more restrictions: once you opt out of the new regime, switching back is limited to one further opportunity, so the decision carries more weight for this group.
Employer TDS and regime choice
Salaried employees should inform their employer of their regime choice at the start of the financial year (or when joining), since the employer computes TDS based on the declared regime. If the choice made at filing time differs from what was declared to the employer, it doesn't create a compliance issue, but it can result in a larger tax payable or refund adjustment when the return is filed.
Can I switch between the old and new tax regime every year?
If you have only salary and other-source income (no business or professional income), yes — you can choose either regime every year when filing your ITR, with no lock-in. If you have business or professional income, the flexibility is more limited: once you opt out of the new regime, you generally get only one further opportunity to switch back, so the choice should be made more carefully.
