March 31 Tax Saving Deadline: Last-Minute Checklist for India

Last updated: 6 May 2026

The Clock Is Ticking on Your Tax Savings

March 31, 2026 isn't just another financial year-end. It's potentially the last time you can save tax the way you've always done.

Here's why: the new Income Tax Act 2025 comes into effect from April 1, 2026. Under the new default regime, most of the deductions you've relied on — 80C, 80D, HRA, home loan interest — either disappear or are significantly reduced.

So if you haven't maxed out your tax-saving investments for FY25-26, you have less than 16 days left. Let's make every one count.

Your Complete Tax-Saving Checklist

1. Section 80C — Up to ₹1.5 Lakh Deduction

This is the big one. Under Section 80C, you can claim deductions up to ₹1,50,000 by investing in any of these:

Investment	Lock-in	Returns	Best For
ELSS Mutual Funds	3 years	12-15%*	Growth + tax saving
PPF	15 years	7.10%	Safe, tax-free returns
5-Year Tax Saver FD	5 years	6-6.5%	Zero-risk investors
NSC	5 years	7.70%	Guaranteed returns
Sukanya Samriddhi	21 years	8.20%	Girl child savings
Life Insurance	Varies	4-6%	Protection + savings

*ELSS returns are market-linked and not guaranteed.

Pro tip: If you haven't invested the full ₹1.5 lakh yet, ELSS gives you the shortest lock-in (3 years) with the highest potential returns. You can start a SIP today and it counts toward this year's deduction.

Don't forget: Your children's school/college tuition fees (up to 2 children) and home loan principal repayment also count under 80C.

2. Section 80D — Health Insurance Premium

You can claim deductions for health insurance premiums:

• For yourself & family: Up to ₹25,000
• For parents (below 60): Additional ₹25,000
• For senior citizen parents: Additional ₹50,000
• Maximum possible: Up to ₹75,000 total deduction

If you haven't bought or renewed your health insurance policy this year, do it before March 31. It's both smart tax planning and essential protection — especially with digital fraud and health emergencies on the rise.

3. Section 80CCD(1B) — NPS Extra ₹50,000

This is the most underused tax-saving tool. Over and above the ₹1.5 lakh under 80C, you can claim an additional ₹50,000 deduction by investing in the National Pension System.

That's a total of ₹2 lakh in deductions (₹1.5L under 80C + ₹50K under 80CCD(1B)). At the 30% tax bracket, that saves you ₹62,400 in tax.

Use our NPS Calculator to see how much your pension corpus would grow.

4. Section 24(b) — Home Loan Interest

If you have a home loan, you can claim up to ₹2 lakh deduction on interest paid. Make sure you:

• Download your annual interest certificate from your bank
• Submit it to your employer's payroll team
• Include it in your ITR filing

Check your EMI breakdown with our EMI Calculator.

5. PPF & SSY Minimum Deposits

If you have a PPF or Sukanya Samriddhi account, you must deposit the minimum amount before March 31 to keep the account active:

• PPF minimum: ₹500 per year
• Sukanya Samriddhi minimum: ₹250 per year

Missing this deadline can result in account deactivation and penalties. Use our PPF Calculator to plan your deposits.

Advance Tax: March 15 Deadline

Important: If you have tax liability beyond what's deducted at source (TDS), you must pay 100% of your advance tax by March 15, 2026. Missing this deadline means interest charges under Sections 234B and 234C.

This particularly applies to:

• Freelancers and consultants
• People with capital gains from stocks or mutual funds
• Rental income earners
• Anyone with income from multiple sources

Why This Year Is Different: The New Income Tax Act

Starting April 1, 2026, India gets a completely new Income Tax Act. Under the new default regime:

• Section 80C deductions — significantly restricted
• HRA exemption — reduced or eliminated
• Home loan interest (Section 24b) — limited
• Standard deduction — increased to ₹75,000 (from ₹50,000)
• NPS employer contribution — increased to 14% (from 10%)

While the new regime has lower tax rates, it offers far fewer deductions. If you've been using the old tax regime with heavy deductions, this is genuinely your last opportunity to maximise savings the traditional way.

Use our Tax Calculator to compare both regimes and see which saves you more.

8 Things to Do Before March 31

1. Check your 80C status — have you invested the full ₹1.5 lakh?
2. Renew health insurance — claim 80D deduction
3. Top up NPS — grab the extra ₹50K deduction
4. Deposit in PPF/SSY — at least the minimum to keep accounts active
5. Download home loan certificate — claim interest under Section 24(b)
6. Submit investment proofs — give your employer the documents
7. Pay advance tax — due by March 15 to avoid interest
8. Review your ITR plan — decide old vs new regime before the year ends

Quick Action Plan Based on Your Situation

If You Have ₹1.5 Lakh to Invest

Put ₹1 lakh in ELSS (best growth potential, 3-year lock-in) + ₹50,000 in NPS (extra deduction). Total deduction: ₹2 lakh. Tax saved: ~₹62,400.

If You Only Have ₹50,000

Put it all in NPS under 80CCD(1B). This is the most tax-efficient move since it's an additional deduction beyond 80C. Tax saved: ~₹15,600.

If You Want Zero Risk

Open a 5-year tax-saving FD. Guaranteed returns of 6-6.5%, and your principal is completely safe. Combine with PPF for the rest.

Frequently Asked Questions

What is the last date for tax-saving investments in India?

For most tax-saving investments under the Old Regime, the deadline is March 31 of the financial year. This includes Section 80C investments (PPF, ELSS, EPF, life insurance), 80D health insurance premiums, 80CCD(1B) NPS contributions, and 24(b) home loan interest. Investments made after March 31 count for the next financial year.

Can I save tax under the New Tax Regime?

Very limited tax-saving options under the New Regime. Only employer-contributed NPS under Section 80CCD(2) and the ₹75,000 standard deduction (FY26-27) for salaried employees apply. No 80C, 80D, HRA, or 80CCD(1B). The New Regime is meant to be lower-rate-but-fewer-deductions, simplifying tax filing.

Is it too late to save tax if I missed February?

No — many tax-saving instruments can be set up online in 1-2 days. ELSS mutual funds and 5-year tax-saver FDs can be opened instantly. PPF and SSY require minimal physical paperwork. Health insurance can be bought online in 30 minutes. As long as the transaction completes by March 31 (with the bank/AMC date stamp), you qualify for that financial year.

What is the minimum to deposit in PPF before March 31?

You must deposit at least ₹500 per financial year to keep your PPF account active. Failing to deposit makes the account inactive (₹50 penalty per missed year to revive). To maximize 80C benefit, deposit the full ₹1.5 lakh — but even ₹500 keeps the account running.

Should I rush to invest in tax-saver FD by March 31?

Only if you can't use better 80C options. Tax-saver FDs lock in for 5 years at 6.5-7% returns (taxable interest). ELSS funds have shorter 3-year lock-in and historically deliver 12-15% (with 12.5% LTCG over ₹1.25L). For most investors, ELSS is better than tax-saver FD even if you have to invest at March-end.

Can I claim 80D for health insurance bought on March 31?

Yes — as long as the policy is issued and premium paid before midnight on March 31, you can claim Section 80D deduction (up to ₹25K self + ₹50K parents) for that financial year. The policy effective date and the payment receipt date both need to be on or before March 31.

What is the advance tax deadline?

Advance tax has 4 deadlines per year: 15 June (15%), 15 September (45%), 15 December (75%), 15 March (100%). Salaried employees with TDS-only income usually don't need to pay advance tax. Self-employed, business owners, and high-rental-income earners must pay to avoid Section 234B/234C interest.

How much can I save by maxing out tax deductions?

For someone in the 30% bracket: 80C (₹1.5L) + 80CCD(1B) NPS (₹50K) + 80D health (₹75K) + 24(b) home loan interest (₹2L) = ₹4.75L deductions = ₹1.48 lakh tax saved. For 20% bracket, savings are about ₹95K. Use our Income Tax Calculator to estimate your specific savings.

Are there any tax savings options after March 31?

Very few. Capital gains exemptions under Section 54/54F (sale of property/equity reinvestment) have separate timelines, sometimes extending into the next FY. Section 80G donations to PM CARES, charitable trusts can be made anytime in the financial year. Most other deductions (80C, 80D, 80CCD) are strictly March 31 deadline.

What investments give tax-free returns under 80C?

Among 80C options, only PPF and EPF give fully tax-free returns at maturity. ELSS gains over ₹1.25 lakh/year are taxed at 12.5% LTCG. Tax-saver FD interest is taxable at slab rate. Life insurance maturity is tax-free under specific conditions (sum assured ≥ 10x annual premium).
