How to Save Income Tax in India: 15 Legal Ways to Reduce Your Tax Bill in 2026

Every rupee of tax saved is a rupee that stays in your hands — and when invested, grows into multiples over time. India’s Income Tax Act provides a remarkably generous set of deductions and exemptions that most taxpayers leave partially or fully unclaimed. This guide covers every major legal tax-saving strategy available for FY 2025-26.

Important Note: Most deductions discussed here are available only under the Old Tax Regime. If you have opted for the New Tax Regime (lower slab rates, no most deductions), evaluate whether switching back would be beneficial. Use our Income Tax Calculator to compare both regimes for your income level.

1. Section 80C — ₹1,50,000 Deduction

The workhorse of Indian tax saving. Investments and expenses eligible under 80C include: ELSS mutual funds, PPF contributions, 5-year tax-saving FDs, life insurance premiums, EPF contributions, NSC, SCSS, home loan principal repayment, tuition fees for children (up to 2 children). The combined maximum deduction is ₹1,50,000. ELSS funds are the highest-return option within this category.

2. Section 80CCD(1B) — Additional NPS Deduction ₹50,000

This is separate from and additional to Section 80C’s ₹1.5 lakh limit. Investing ₹50,000 in NPS Tier I qualifies for an exclusive additional deduction under 80CCD(1B). For a 30% bracket taxpayer, this saves approximately ₹15,000–₹17,500 in annual tax. No other instrument provides a deduction beyond the 80C ceiling.

3. HRA Exemption — House Rent Allowance

Salaried employees living in rented accommodation can claim HRA exemption on the least of: (a) actual HRA received, (b) 50% of basic salary (metro cities) or 40% (non-metro), (c) actual rent paid minus 10% of basic salary. Submit rent receipts and landlord PAN (for annual rent exceeding ₹1 lakh) to your employer. Calculate your exemption with our HRA Exemption Calculator.

4. Section 80D — Health Insurance Premiums

Premiums paid for health insurance qualify for deduction: up to ₹25,000 for self, spouse, and dependent children; an additional ₹25,000 for parents below 60 (₹50,000 if parents are senior citizens). Maximum combined deduction: ₹1,00,000 per year. Additionally, expenses on preventive health check-ups (up to ₹5,000 within the overall limit) are also deductible.

5. Home Loan Interest — Section 24(b)

Interest paid on a home loan for a self-occupied property is deductible up to ₹2,00,000 per year under Section 24(b). For a property given on rent, there is no upper limit — all interest is deductible. For a 30% taxpayer paying ₹2 lakh in home loan interest, this deduction saves ₹60,000 per year.

6. Home Loan Principal — Section 80C

The principal component of home loan EMIs is deductible under Section 80C (within the ₹1.5 lakh limit). If you are already maxing out 80C with other instruments, this provides no additional deduction — but many home buyers are not fully aware of this overlap.

7. Section 80EEA — First-Time Home Buyer Interest

First-time homebuyers of affordable housing (stamp duty value up to ₹45 lakh) can claim an additional ₹1,50,000 interest deduction under Section 80EEA, over and above the ₹2 lakh under 24(b). Combined maximum home loan interest deduction: ₹3.5 lakh/year. (Subject to eligibility conditions — verify with a tax advisor).

8. Leave Travel Allowance (LTA)

LTA can be claimed twice in a 4-year block for domestic travel expenses (airfare or rail fare for self and family). The exemption covers travel costs only, not hotel or food. Proper documentation (boarding passes, tickets) is essential.

9. Standard Deduction — ₹75,000

All salaried employees receive a flat standard deduction of ₹75,000 (increased from ₹50,000 in FY 2024-25) without any documentation requirement. This directly reduces gross taxable salary.

10. Section 80E — Education Loan Interest

Interest paid on education loans for higher studies (self, spouse, children, or legal ward) is fully deductible under Section 80E — no upper limit — for up to 8 years from the year repayment begins. This is one of the few unlimited deductions available.

11. Section 80G — Donations to Charitable Organisations

Donations to approved charities, religious institutions, and government relief funds qualify for deduction under 80G. Depending on the recipient organisation, the deduction is 50% or 100% of the donated amount, with or without qualifying limits. Keep receipts and confirm the institution has valid 80G registration.

12. Section 80TTA / 80TTB — Savings Account Interest

Individuals below 60: savings account interest up to ₹10,000 per year is exempt under 80TTA. Senior citizens: interest income up to ₹50,000 from savings accounts, FDs, and RDs is exempt under 80TTB (which replaces 80TTA for seniors).

13. Section 10(14) — Special Allowances

Several allowances are exempt from tax when received for legitimate work purposes: conveyance allowance, telephone/mobile reimbursement, uniform allowance, children’s education allowance (₹100/child/month, up to 2 children), and hostel allowance. Ensure these are structured in your CTC to maximise tax efficiency.

14. Capital Gains Harvesting — Section 112A Exemption

Long-term capital gains from equity mutual funds up to ₹1,25,000 per financial year are exempt from tax under Section 112A. If your equity gains are approaching this threshold, consider a strategy of selling and immediately repurchasing to “harvest” the exemption annually — effectively creating a higher tax cost basis for future gains. Our Capital Gains Tax Calculator helps plan this.

15. Gratuity and Retrenchment Compensation Exemptions

Gratuity received by government and private sector employees is exempt from tax up to specific limits under Section 10(10). Retrenchment compensation is exempt up to ₹5 lakh under Section 10(10B). These are automatically applied by employers but worth understanding when changing jobs or retiring. Use our Gratuity Calculator to estimate your entitlement.
