How to Save Income Tax in India 2026-27: Complete Guide with Calculator

Tax season is here, and every salaried Indian is asking the same question: how can I save more income tax legally? With the FY 2026-27 tax filing season approaching, it is crucial to understand all available deductions, exemptions, and strategies to minimise your tax liability. This comprehensive guide covers 15 proven methods with practical examples.

Old Regime vs New Regime: Which Saves More Tax?

The first decision every taxpayer must make is choosing between the old and new tax regimes. The new regime offers lower slab rates but eliminates most deductions. The old regime has higher rates but allows deductions under Sections 80C, 80D, 24(b), and more.

Quick rule of thumb: If your total deductions exceed Rs 3.75 lakh, the old regime usually saves more tax. If your deductions are below Rs 2 lakh, the new regime is likely better. Use our Income Tax Calculator to compare both regimes with your actual numbers.

• New regime: No tax up to Rs 12 lakh (with Rs 75,000 standard deduction). Tax rates: 5% (3-7L), 10% (7-10L), 15% (10-12L), 20% (12-15L), 25% (15-20L), 30% (above 20L)
• Old regime: Basic exemption Rs 3 lakh. Tax rates: 5% (3-6L), 20% (6-9L), 30% (above 9L). But allows deductions of Rs 3-6 lakh or more

1. Section 80C — Rs 1.5 Lakh Deduction (Old Regime)

This is the most popular tax-saving section. You can claim up to Rs 1,50,000 across multiple investments:

• PPF (Public Provident Fund): Currently offering 7.1% tax-free returns. 15-year lock-in with partial withdrawal after 7 years. Use our PPF Calculator to project your maturity amount.
• ELSS Mutual Funds: Equity-linked savings with only 3-year lock-in. Potential for 12-15% returns. Use our ELSS Tax Calculator.
• EPF/VPF: Your EPF contribution already counts. Voluntary PF (VPF) offers the same interest rate with additional contributions.
• Life Insurance Premiums: Premiums paid for self, spouse, and children qualify.
• Children Tuition Fees: School/college tuition fees for up to 2 children.
• Home Loan Principal Repayment: The principal component of your EMI. Calculate your break-up with our EMI Calculator.
• National Savings Certificate (NSC): 5-year government savings scheme.
• Sukanya Samriddhi Yojana: For girl child. High interest + tax-free maturity. Use our Sukanya Samriddhi Calculator.

2. Section 80D — Health Insurance (Rs 25,000-1,00,000)

Premiums paid for health insurance are deductible:

• Self, spouse, children: Up to Rs 25,000 (Rs 50,000 if any member is senior citizen)
• Parents: Additional Rs 25,000 (Rs 50,000 if parents are senior citizens)
• Maximum possible deduction: Rs 1,00,000 (if both you and parents are 60+)
• Preventive health check-up: Rs 5,000 included within the above limits

3. HRA Exemption — Save Rs 50,000-2,00,000+

If you live in a rented house and receive HRA from your employer, you can claim a significant exemption. The exempt amount is the minimum of three values:

• Actual HRA received
• Rent paid minus 10% of basic salary
• 50% of basic salary (metro) or 40% (non-metro)

Use our HRA Calculator to find your exact exemption. Even if you pay rent to your parents, this deduction applies — just ensure you have rent receipts. Generate them instantly with our Rent Receipt Generator.

4. Section 80CCD(1B) — NPS Extra Rs 50,000

Over and above the 80C limit of Rs 1.5 lakh, you can claim an additional Rs 50,000 for contributions to the National Pension System (NPS). This means a total Rs 2 lakh deduction from just 80C + NPS. Use our NPS Calculator to see projected retirement corpus.

5. Home Loan Interest — Section 24(b) Rs 2,00,000

Interest paid on a home loan for a self-occupied property is deductible up to Rs 2,00,000 per year under Section 24(b). Combined with the principal deduction under 80C, a home loan can save you Rs 3.5 lakh+ in deductions. Calculate your interest vs principal split with our Home Loan Calculator.

6. Standard Deduction — Rs 75,000 (Both Regimes)

Every salaried individual gets a flat Rs 75,000 standard deduction from gross salary in FY 2026-27. This applies in both old and new regimes — no investment needed.

7. Section 80E — Education Loan Interest

The entire interest paid on an education loan is deductible for 8 years from the year of repayment. No upper limit on the deduction amount. Use our Education Loan Calculator to plan repayment.

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

Interest earned on savings accounts is deductible up to Rs 10,000 (80TTA) for those below 60, or Rs 50,000 (80TTB) for senior citizens. This includes interest from savings accounts in banks, post offices, and cooperative societies.

Tax Saving Example: Rs 12 Lakh Salary

Let us see how much an employee earning Rs 12 lakh can save under the old regime:

• Standard deduction: Rs 75,000
• Section 80C (PPF + ELSS + EPF): Rs 1,50,000
• Section 80D (health insurance): Rs 50,000
• Section 80CCD(1B) NPS: Rs 50,000
• HRA exemption: Rs 1,20,000 (approx.)
• Total deductions: Rs 4,45,000
• Taxable income: Rs 12,00,000 - Rs 4,45,000 = Rs 7,55,000
• Tax payable (old regime): Rs 52,500 + cess = Rs 54,600
• Tax payable (new regime): Rs 60,000 + cess = Rs 62,400
• Old regime saves Rs 7,800 more

Smart Tax Planning Tips

• Start early: Do not wait until March. Begin SIP investments in ELSS or PPF from April itself to benefit from compounding and avoid last-minute rush.
• Use your salary structure: Ask your employer to restructure salary to include more HRA, LTA, food coupons, and NPS contribution for maximum tax savings.
• File ITR even if not mandatory: Filing returns creates a record, helps in getting loans and visas, and allows you to carry forward losses.
• Keep all receipts: Maintain rent receipts, medical bills, insurance receipts, and investment proofs throughout the year.

Frequently Asked Questions

Q: Can I switch between old and new regime every year?

Yes. Salaried individuals can switch between the old and new tax regime every financial year at the time of filing their ITR. However, individuals with business income can only switch once in their lifetime.

Q: Is PPF better than ELSS for tax saving?

PPF offers guaranteed returns (7.1%) with complete tax-free maturity but has a 15-year lock-in. ELSS offers potentially higher returns (12-15%) with only 3-year lock-in but gains above Rs 1.25 lakh are taxed at 12.5%. Choose based on your risk appetite and investment horizon. Use our SIP Calculator to compare projected returns.

Q: Can I claim both HRA and home loan interest deduction?

Yes, if you live in a rented house in one city (where you work) and have a home loan for a property in another city. Both deductions can be claimed simultaneously under the old regime.
