How to Save Income Tax in India Legally — 2026 Complete Guide
Every salaried Indian pays more income tax than they legally have to. The reason? Most people either don't know all the deductions available to them, or they find out about them in March when it's too late to act. This guide walks you through every legal tax-saving option for FY 2025-26 — with exact amounts, limits, and which regime they apply to.
First: Old Regime vs New Regime — Which Are You In?
Before saving tax, you need to know your regime. From FY 2024-25, the New Regime is the default. If you didn't explicitly opt for the old regime with your employer, you're in the new regime. The new regime offers lower slab rates but allows almost no deductions. The old regime allows all the deductions below but has higher slabs.
Complete List of Tax-Saving Investments — Old Regime
| Section | Investment Options | Max Deduction | Tax Saved (30% slab) |
|---|---|---|---|
| 80C | ELSS Mutual Funds, PPF, EPF, LIC, NSC, ULIP, Home Loan Principal, Tuition Fees, SSY | ₹1,50,000 | ₹46,800 |
| 80D | Health Insurance Premium (self+family) | ₹25,000 (₹50,000 if parents are senior citizens) | ₹7,800–₹15,600 |
| 80CCD(1B) | NPS Tier I — additional contribution beyond 80C | ₹50,000 | ₹15,600 |
| 24(b) | Home Loan Interest (self-occupied property) | ₹2,00,000 | ₹62,400 |
| 10(13A) | HRA Exemption (if living in rented house) | Min of 3 conditions | Varies |
| 80E | Education Loan Interest | No limit (up to 8 years) | 30% of interest paid |
| 80TTA | Savings Account Interest | ₹10,000 | ₹3,120 |
| Standard Deduction | Flat deduction for all salaried | ₹50,000 | ₹15,600 |
Best Tax-Saving Options Ranked by Value
1. ELSS Mutual Funds (Best under 80C)
ELSS (Equity Linked Savings Scheme) gives you the same ₹1,50,000 deduction as PPF or LIC, but with two major advantages: only 3-year lock-in (shortest in 80C) and potential for 12–15% CAGR returns vs 7.1% for PPF. For anyone under 45 with a moderate risk appetite, ELSS dominates every other 80C option.
2. NPS 80CCD(1B) — Extra ₹50,000 Over 80C
This is often overlooked. After maxing your ₹1,50,000 under 80C, you can invest an additional ₹50,000 in NPS Tier I under Section 80CCD(1B). This is completely separate from the 80C limit. At the 30% slab, this saves you ₹15,600 extra in tax every year.
3. Health Insurance 80D — Non-Negotiable
Health insurance premium for self + spouse + children = ₹25,000 deduction. If your parents are senior citizens (60+), an additional ₹50,000 for their premium. Total possible: ₹75,000 deduction = ₹23,400 tax saved. And you get actual health coverage — this is truly a no-brainer.
4. Home Loan — ₹2,00,000 Interest Deduction
If you have a home loan on a self-occupied property, the interest you pay (up to ₹2,00,000/year) is fully deductible under Section 24(b). On a ₹50 lakh loan at 8.5%, your annual interest in early years is ₹4+ lakhs, but only ₹2 lakhs can be claimed. Still saves ₹62,400 in tax at 30% slab.

In the new regime, most deductions above are not available. The only deductions allowed are:
- Standard deduction: ₹75,000 (increased from ₹50,000)
- Employer NPS contribution: Deductible under 80CCD(2) — ask HR to restructure salary to include employer NPS
- Section 87A rebate: Zero tax if total income up to ₹7,00,000
In the new regime, your focus should shift from deductions to income restructuring: ask HR to include more tax-free components like meal coupons (₹26,400/year tax-free), leave travel allowance (LTA), and professional development allowance.
