🧾 Tax Saving in India: Every Legitimate Deduction You Should Be Using

The Indian Income Tax Act contains over 100 sections providing deductions, exemptions, and benefits. Most salaried employees are aware of Section 80C and very little else, and the result is consistent overpayment by people who could legally retain thousands of rupees more each year simply by claiming what they are already entitled to. Everything below applies specifically to the old tax regime, which still tends to win for many salaried individuals with income above roughly 7 lakh rupees once deductions are fully utilised.

Section 80C — the 1.5 lakh rupee limit most people only partially use

• ELSS mutual funds: The instrument with the strongest return potential within 80C, with a relatively short 3-year lock-in and market-linked growth.
• EPF and PPF contributions: Risk-free, government-backed, and guaranteed at their stated rates.
• Life insurance premiums: Qualify only if the annual premium is 10% or less of the policy’s sum assured — a detail many people miss.
• Home loan principal repayment: Qualifies under 80C, but only from the point of possession onward.

The 1.5 lakh rupee cap is shared across all of these instruments combined, not per instrument — a common point of confusion. Once you have identified which combination already fills this limit through existing EPF and insurance, additional 80C investments beyond that point provide no further tax benefit.

Section 80D — health insurance, a frequently underused 1,00,000 rupee opportunity

Individuals below 60 can claim up to 25,000 rupees for health insurance premiums covering themselves, a spouse, and dependent children. A separate, additional deduction of 25,000 rupees is available for premiums paid for parents below 60, rising to 50,000 rupees if those parents are senior citizens.

This means a taxpayer with senior citizen parents can potentially claim up to 75,000 to 1,00,000 rupees combined across both halves of this section — one of the most underused tax benefits in practice, since many people insure themselves but never separately insure or claim for their parents’ premiums.

Section 80CCD(1B) — an additional 50,000 rupees through NPS

This deduction is entirely separate from the 1.5 lakh rupee 80C limit, meaning it is genuinely additive rather than competing for the same cap. At a 30% tax bracket, a full 50,000 rupee NPS contribution saves roughly 15,600 rupees in tax immediately, making it one of the highest-value, lowest-effort deductions available to higher earners specifically.

HRA exemption — often miscalculated

House Rent Allowance exemption follows a least-of-three-conditions rule: the actual HRA received, rent paid minus 10% of basic salary, or 50% of basic salary in a metro city (40% in non-metro). Many salaried employees either fail to claim this at all if they live with family, even when paying genuine, documented rent to a parent, or miscalculate the exemption by assuming the full HRA received is automatically tax-free.

The old regime vs new regime decision

This decision is not fixed for life — salaried individuals can generally choose between regimes each year when filing, making it worth recalculating both scenarios annually rather than defaulting to whichever regime was chosen previously.

A practical year-end checklist

Most overpaid tax in India is not the result of high rates. It is the result of deductions people were always entitled to, but never claimed.
