Overview
As the financial year 2025-26 nears its close, March 31, 2026, becomes the golden deadline for every taxpayer in India. This isn't just a date on the calendar, it's your final chance to reduce tax liability, claim deductions, and stay clear of late penalties or notices.
Missing even one compliance task can lead to unnecessary tax outflow or interest charges. From Section 80C investments to proof submissions and advance tax payments, every move counts this month. Let's walk through the smart financial tasks you must complete before March 31 to save tax and avoid any unpleasant surprises.
Tax-Saving Investments (Section 80C)
Under the old tax regime, Section 80C allows you to claim deductions up to ₹1.5 lakh in a financial year. To maximize savings, ensure these investments are completed before March 31:
- Public Provident Fund (PPF) - Safe, long-term savings with tax-free returns.
- National Pension System (NPS) - Offers both retirement benefits and additional deductions under 80CCD(1B).
- Sukanya Samriddhi Yojana (SSY) - Ideal for parents of girl children.
- Life Insurance Premiums, ELSS Mutual Funds, and Home Loan Principal Repayment also qualify.
Also, make minimum required contributions to PPF, SSY, and NPS accounts to keep them active and compliant
Health Insurance Deductions (Section 80D)
Premiums paid for health insurance policies can lower your taxable income.
- Up to ₹25,000 for self and family
- Additional ₹25,000 for parents (₹50,000 if they are senior citizens)
Keep payment proofs handy, as cash payments don't qualify — only digital or cheque transactions are accepted.
Submit Investment Proofs to Employer
If you declared investments earlier, submit actual proofs to your employer before the payroll cut-off. Missing this step could lead to higher TDS deductions in March. Keep copies of ELSS statements, insurance receipts, rent agreements, and tuition fee receipts to validate claims
Pay Advance Tax Before the Deadline
For taxpayers with significant non-salaried income (like rent, business, or capital gains), advance tax must be paid by March 15, 2026. Missing this can trigger interest under Sections 234B and 234C, along with penalties
Maximize Last-Minute IRA or NPS Contributions
You can still contribute to an Individual Retirement Account (IRA) or NPS for FY 2025-26 until April 15, 2026, and claim it in your return.
For NPS, don't forget the extra deduction of ₹50,000 under Section 80CCD(1B) — a powerful addition for high earners.
Review Your Income and Deductions
This is a crucial self-audit:
- Match total income from salary, business, rent, and interest.
- Ensure all deductions (80C, 80D, 80TTA, HRA, home loan interest under Section 24b) are claimed.
- Reconcile Form 26AS and AIS (Annual Information Statement) with your records to ensure no mismatch that might attract scrutiny.
File or Update Your Return If Needed
If you have discovered an error or missed income in a previously filed return, you can file an updated return (ITR-U) before March 31, 2026. This prevents the risk of future notices or penalties for underreporting.
