How to Save Income Tax in India: 12 Legal Methods Ranked by Impact

Standard deduction (₹75,000 under new regime, ₹50,000 under old regime) is the easiest saving available to salaried employees. It requires no investment, no documentation, and no action. It is automatically applied. At the 30% slab, this saves ₹23,400 per year including cess. If you are not claiming it, your employer or CA is making an error.

HRA exemption is the second zero-effort saving for people who rent. The calculation — minimum of actual HRA received, rent paid minus 10% of basic, or 50%/40% of basic — sounds complex but yields large savings for anyone paying meaningful rent in a metro. A person earning ₹15 lakh basic and paying ₹25,000 rent monthly in Bengaluru can exempt ₹1.5–2 lakh annually. This requires keeping rent receipts and the landlord's PAN if rent exceeds ₹1 lakh per year.

LTA (Leave Travel Allowance) exemption applies to actual travel costs for domestic journeys taken by employees. Many people leave this unclaimed because they forget to submit bills. If your salary structure includes LTA, claim it. It requires nothing beyond actual travel and ticket receipts.

Section 80C allows up to ₹1.5 lakh deduction and covers EPF contributions (which may already be happening via payroll), ELSS mutual funds, PPF, NSC, 5-year FD, SSY, and life insurance premiums. The highest-returning and most liquid option is ELSS — equity-linked savings schemes with a 3-year lock-in. At 30% slab, investing ₹1.5 lakh in ELSS saves ₹46,800 in tax plus generates equity market returns on top.

EPF contributions are often under-recognized as 80C benefit. If your employer deducts 12% of basic toward EPF, that counts toward the ₹1.5 lakh limit. Many salaried people are already at ₹80,000–₹1 lakh in 80C through EPF alone and only need ₹50,000–₹70,000 in additional investments.

PPF is excellent for conservative investors — 7.1% tax-free interest with Section 80C benefit — but the 15-year lock-in and annual deposit requirement make it less flexible than ELSS. LIC and traditional insurance policies perform the worst from a pure financial standpoint. They conflate insurance and investment, deliver low returns, and lock up capital for decades. Avoid them as a tax-saving tool unless you genuinely need the insurance cover.

Section 80CCD(1B) offers an additional ₹50,000 deduction beyond the 80C limit for NPS contributions. This is separate from the ₹1.5 lakh 80C bucket. At the 30% slab, contributing ₹50,000 to NPS saves ₹15,600 in additional tax. NPS also builds a retirement corpus with market-linked returns. The partial lock-in until 60 is real, but for long-term retirement savings, this is one of the best tax-saving tools available.

Section 80D covers health insurance premiums: ₹25,000 for self and family, plus ₹50,000 for senior citizen parents. If you are buying health insurance anyway — which you should be — this deduction is essentially free savings. Many professionals forget to claim parents' health insurance under 80D and leave ₹15,000–₹25,000 in deductions on the table.

Section 24(b) allows deduction of home loan interest up to ₹2 lakh per year under the old regime. For anyone servicing a home loan in the first 10 years when interest is the dominant component of EMI, this is often the single largest deduction available. Combined with 80C deduction for principal repayment, home ownership can reduce taxable income by ₹3.5 lakh per year.

Section 80E covers interest on education loans for self or children. There is no upper limit on the amount, and the deduction applies for up to 8 years or until the interest is fully paid. If you or a family member has a higher education loan, every rupee of interest paid is deductible — a benefit most people are unaware of.

Salary restructuring is one of the highest-leverage moves but requires employer cooperation. Shifting part of CTC to meal vouchers, mobile and internet allowance, books and periodicals, transport, or leave encashment components can reduce the taxable salary component significantly. A good HR or finance team can legally structure ₹50,000–₹1 lakh of annual CTC into exempt allowances.

Capital gains harvesting in the context of equity mutual funds is worth knowing. Long-term capital gains up to ₹1.25 lakh per year are tax-free. If you hold equity mutual funds or stocks, redeeming and rebuying to book gains within the free threshold each year (tax-loss harvesting in reverse) avoids future bunching of gains. This requires no immediate cash outflow and can save meaningful tax over a decade of investing.
