How to Save Income Tax in India: Complete Guide for FY 2025-26
Paying more tax than you need to is one of the most common financial mistakes. India's tax laws offer numerous legal ways to reduce your tax liability — from Section 80C investments to HRA exemptions. This guide covers every major deduction available for FY 2025-26.
Step 1: Choose the right tax regime
The most important tax decision for FY 2025-26 is choosing between the Old Regime and the New Regime. Budget 2025 made the New Regime significantly more attractive with a zero-tax threshold of ₹12 lakh (effectively ₹12.75 lakh for salaried individuals after the ₹75,000 standard deduction).
| Income Range | New Regime Rate | Old Regime Rate |
|---|---|---|
| Up to ₹4,00,000 | Nil | Nil (up to ₹2.5L) |
| ₹4L – ₹8L | 5% | 5% (₹2.5L–₹5L) |
| ₹8L – ₹12L | 10% | 20% (₹5L–₹10L) |
| ₹12L – ₹16L | 15% | 30% (above ₹10L) |
| Above ₹24L | 30% | 30% |
The New Regime is better for most people with income under ₹15 lakh and limited deductions. The Old Regime can still win if you have large 80C investments, significant HRA, and home loan interest. Use our Income Tax Calculator to compare both regimes instantly.
Section 80C: The ₹1.5 lakh deduction (Old Regime only)
Section 80C allows you to deduct up to ₹1,50,000 from your taxable income. This is only available under the Old Regime. Here are the most popular 80C instruments:
ELSS Mutual Funds
Equity Linked Savings Scheme — 3-year lock-in, market-linked returns (historically 12–15% CAGR). Best for long-term wealth creation.
EPF (Employee Provident Fund)
Your monthly PF contribution automatically qualifies. Employer contribution does not count toward 80C.
PPF (Public Provident Fund)
15-year lock-in, currently 7.1% interest, fully tax-free maturity. Excellent for conservative investors.
Life Insurance Premium
Premiums paid for life insurance policies qualify. Term insurance premiums are eligible.
NSC (National Savings Certificate)
5-year lock-in, 7.7% interest (taxable). Safe, government-backed.
Home Loan Principal Repayment
The principal portion of your home loan EMI qualifies under 80C.
Children's Tuition Fees
Tuition fees paid for up to 2 children qualify. Hostel and transport fees do not.
Section 80D: Health insurance deduction
Health insurance premiums qualify for deduction under Section 80D (Old Regime only):
| Coverage | Deduction Limit |
|---|---|
| Self, spouse, children (below 60) | Up to ₹25,000 |
| Self, spouse, children (60+) | Up to ₹50,000 |
| Parents (below 60) | Additional ₹25,000 |
| Parents (60+) | Additional ₹50,000 |
| Maximum possible deduction | ₹1,00,000 |
HRA Exemption: Save tax on rent
If you live in a rented house and receive HRA as part of your salary, you can claim an exemption under the Old Regime. The exempt amount is the lowest of:
Actual HRA received from employer
50% of basic salary (metro cities: Delhi, Mumbai, Chennai, Kolkata) or 40% (non-metro)
Actual rent paid minus 10% of basic salary
Use our HRA Exemption Calculator to find your exact exempt amount.
Home loan deductions (Old Regime)
Section 24(b)
Interest paid on home loan: up to ₹2,00,000 per year for self-occupied property. No limit for let-out property.
Section 80C
Principal repayment: up to ₹1,50,000 (combined with other 80C investments).
Section 80EEA
Additional ₹1,50,000 deduction on interest for first-time homebuyers (stamp duty value ≤ ₹45 lakh). Subject to conditions.
NPS: Extra ₹50,000 deduction under 80CCD(1B)
Contributions to the National Pension System (NPS) qualify for an additional deduction of up to ₹50,000 under Section 80CCD(1B) — over and above the ₹1.5 lakh 80C limit. This is available only under the Old Regime. If you are in the 30% tax bracket, this alone saves ₹15,600 in tax.
