End-of-Year Financial Checklist: What to Do Before March 31

The Indian financial year runs from April 1 to March 31. As March 31 approaches, certain financial tasks become time-sensitive — they either expire at midnight on March 31 or have consequences that can't be reversed once the new financial year begins.

Why the March 31 Deadline Matters

Several tax-saving provisions reset on April 1:

• Section 80C investment limit resets to zero
• LTCG tax exemption (Rs.1.25 lakh) resets
• Advance tax Q4 deadline is March 15
• Any investment counted for a financial year must be completed by March 31 of that year

Missing these is not just inconvenient — it can mean thousands of rupees in unnecessary tax or interest.

The March 31 Checklist

Tax-Saving Investments (Section 80C and Beyond)

Check your current 80C utilisation. Section 80C gives deductions up to Rs.1.5 lakh across all qualifying instruments: ELSS investments, PPF contributions, EPF employee contribution, LIC premium, NSC, home loan principal, children's tuition fees. Pull up all contributions made this financial year and calculate the gap, if any.

Top up through ELSS if needed. ELSS (Equity Linked Savings Scheme) units are typically allocated same-day when purchased through major platforms. This makes ELSS the most convenient last-minute 80C investment. Units purchased before March 31 count for the current financial year.

PPF annual minimum contribution. If you have a PPF account, ensure a minimum Rs.500 was deposited in the financial year. Failure to maintain the minimum makes the account dormant and requires a fine to reactivate. The maximum annual PPF contribution is Rs.1.5 lakh, which also counts toward 80C.

NPS for 80CCD(1B) additional deduction. Section 80CCD(1B) allows an additional deduction of Rs.50,000 for NPS Tier 1 contributions — this is over and above the Rs.1.5 lakh Section 80C limit. If you haven't contributed this year, complete it before March 31 through the NPS portal or through your employer.

Health Insurance (Section 80D)

Check if your health insurance premium for the year has been paid. Section 80D allows deductions on health insurance premiums: Rs.25,000 for self, spouse, and children; additional Rs.25,000 (or Rs.50,000 for senior citizens) for parents' health insurance. If the premium payment falls in the current financial year (check your policy renewal date), confirm it has been paid and keep the receipt.

LTCG Tax Harvesting

Check if you have equity fund units older than 12 months. For each equity mutual fund holding, identify lots held more than 12 months with unrealised gains. If total unrealised LTCG across all such lots is below Rs.1.25 lakh for the financial year, consider redeeming and immediately reinvesting — resetting your cost basis tax-free.

This harvesting strategy works because the Rs.1.25 lakh annual exemption resets on April 1. By using it before March 31 each year, you progressively increase your cost basis, reducing future tax liability on the same portfolio.

Investment Proofs to Employer

Submit all proofs to HR/payroll by their stated deadline (typically January or February). Documents needed: ELSS investment statements, LIC premium receipts, home loan interest certificate, home loan principal certificate, rent receipts for HRA, health insurance premium receipt. Missing the employer's deadline means higher TDS — though you recover it via ITR filing, it's an avoidable cash flow issue.

If you missed the employer deadline: No separate action needed from the employer — claim all deductions directly in your ITR filing in July. The deductions are your right regardless of whether the employer was notified.

Advance Tax (For Non-Salaried Income)

Final advance tax instalment due March 15. If you have self-employment income, freelance income, rental income, capital gains, or any income where TDS has not fully covered your tax liability — and the expected tax liability exceeds Rs.10,000 — the final advance tax instalment must be paid by March 15. Missing this triggers interest under Section 234B and 234C at 1% per month on the shortfall.

Annual Goal Review

Are your financial goals on track for the year? Before the financial year closes, check: are SIP contributions at the planned level? Is the emergency fund target being met? Is any goal significantly behind — and can a catch-up contribution before March 31 help?

Timeline: February Through March 31

Date	Action
February 1-15	Submit investment proofs to HR/payroll
March 1	Check 80C utilisation gap
March 1-14	ELSS, PPF, NPS top-up if needed
March 15	Final advance tax Q4 instalment due
March 20-28	LTCG harvesting (redeem and reinvest)
March 31	All financial year investments must be completed

Detailed LTCG Harvesting: How to Execute It

LTCG tax harvesting is one of the most consistently underused tax planning tools available to Indian equity investors. Here is the complete process to execute it correctly before March 31:

Step 1: Identify eligible holdings. You need equity mutual fund or listed equity units held for more than 12 months. Log into your investment platform (Zerodha, Groww, Kuvera) and go to the capital gains section. Most platforms now show a split between short-term and long-term holdings for each fund.

Step 2: Calculate unrealised LTCG. Look at the long-term holdings and their unrealised gains. The total unrealised LTCG from all long-term equity holdings across all platforms is the number you're working with. If this is below Rs.1.25 lakh, you can redeem all of it tax-free.

Step 3: Redeem the eligible amount. Redeem the units with unrealised LTCG below Rs.1.25 lakh. On Zerodha Coin: Portfolio → Select fund → Redeem → Enter units. On Groww: Portfolio → Fund → Withdraw → Units/Amount. On Kuvera: Portfolio → Fund → Withdraw.

Step 4: Wait for credit and immediately reinvest. The redemption typically credits in 1–3 business days. As soon as the money arrives in your bank account, reinvest it in the same fund (or an equivalent fund if there are exit loads on the original). This restores your position in the market and resets your cost basis to the current NAV.

The result: Your cost basis for those units is now Rs.1.25 lakh higher than it was before. When you eventually sell in the future, you pay LTCG only on gains above this new higher cost basis. If you repeat this every year, you systematically increase your cost basis, reducing future tax liability year after year.

Important constraints: The LTCG exemption of Rs.1.25 lakh applies to your total net LTCG from all equity investments in the financial year — not separately to each fund. Include any equity shares sold during the year in this calculation. If you have already realised Rs.70,000 in LTCG from other equity transactions, you can only harvest Rs.55,000 more without triggering tax.

Advance Tax Calculation: A Simple Method

If you need to pay advance tax and haven't done a detailed calculation, here is a practical method for the Q4 payment due March 15:

Step 1: Estimate your total income for the financial year. For salaried individuals with predictable income, use: (monthly gross salary × months worked) + any bonus received + rental income + freelance income received.

Step 2: Estimate total capital gains. Pull the capital gains report from your broker (Zerodha's Tax P&L section is excellent for this). Add any capital gains from mutual fund redemptions.

Step 3: Apply deductions. Standard deduction Rs.75,000. Section 80C up to Rs.1.5 lakh. 80D health insurance premium. 80CCD(1B) NPS contribution up to Rs.50,000 (old regime only).

Step 4: Calculate tax on taxable income using your applicable regime (old or new). Subtract TDS already deducted by your employer (from Form 16 part A, or estimate from salary slips).

Step 5: The balance tax is your advance tax liability. If this exceeds Rs.10,000, you must pay it.

Pay via net banking on the income tax portal (incometax.gov.in) under "e-Pay Tax" → Challan 280 → Advance Tax → Assessment Year (the AY for the current FY, e.g., AY 2026-27 for FY 2025-26).

Section-by-Section Tax Review for the Full Year

The March 31 deadline applies across multiple sections. A complete review ensures nothing is missed:

Section 80C (Rs.1.5 lakh limit):

• EPF contribution (employee side) — auto-deducted, check your salary slip for annual total
• PPF contributions made during the year — check your PPF passbook
• ELSS investments — check your mutual fund CAS
• LIC and other life insurance premiums paid
• Home loan principal repayment (from your loan statement)
• Children's school tuition fees paid (up to two children)
• NSC, SCSS, 5-year bank FD

Total all these and confirm whether the Rs.1.5 lakh limit is reached. If not, the gap can be filled with ELSS investments until March 31.

Section 80D (health insurance premiums):

• Premium paid for self, spouse, and children's health insurance — up to Rs.25,000
• Additional premium for parents' health insurance — up to Rs.25,000 (or Rs.50,000 for senior citizen parents)
• Rs.5,000 sub-limit within 80D for preventive health checkups

Section 24(b) (home loan interest):

• Interest paid on home loan during the year — up to Rs.2 lakh deduction on self-occupied property
• Get the interest certificate from your bank or housing finance company (typically issued in March)

Section 80CCD(1B) (NPS Tier 1 — Rs.50,000 additional):

• This is over and above the Rs.1.5 lakh 80C limit
• If you haven't made an NPS contribution this year and are in the old tax regime, this is one of the most valuable deductions available — contributes Rs.50,000 to your retirement corpus while reducing taxable income

HRA deduction (if claiming):

• Ensure rent receipts for the full year are collected and filed
• If annual rent paid exceeds Rs.1 lakh (Rs.8,333/month), your landlord's PAN is required — collect it before March 31 and declare it to your employer

What Happens on April 1

At midnight on March 31, the following reset:

• The 80C Rs.1.5 lakh limit resets to zero for the new financial year
• The Rs.1.25 lakh LTCG annual exemption resets
• The financial year changes from FY 2025-26 to FY 2026-27
• All investments and transactions from April 1 onwards belong to the new financial year

The first few days of April are when you should:

• Contribute to PPF for the new year before the 5th to earn maximum interest (see the automation article for why April 5 matters)
• Set up your tax planning for the new year — confirm Section 80C contribution schedule (SIPs, LIC, EPF)
• Update your employer's TDS declaration form with deductions planned for the new year — this ensures correct TDS from the first salary of the new financial year

Common Year-End Mistakes and How to Avoid Them

Leaving 80C gap unfilled until the last two days of March. Investment platforms experience extremely high load on March 29, 30, and 31. NAV allocation for ELSS may be delayed by one business day if servers are overloaded. If you invest on March 31 and the order confirmation is delayed to April 1, the investment counts for the new financial year — your 80C claim is gone. Complete ELSS investments by March 25 to avoid this entirely.

Doing LTCG harvesting too close to March 31. Equity fund redemptions typically take 2–3 business days to credit to your bank account, plus another 1–2 business days to reinvest in the same fund. If you redeem on March 28 and want to reinvest in the same fund by March 31, the reinvestment may not process in time. Plan for all LTCG harvesting to be complete by March 20–22. The harvest itself (redemption order) should be placed with enough time for the reinvestment to also fall within the same financial year.

Confusing TDS with advance tax. TDS is deducted at source — your employer deducts it from your salary, your bank deducts it on FD interest. Advance tax is what you pay proactively on income that doesn't have TDS at source (freelance income, capital gains, rental income). Both are taxes paid during the year and both reduce your final ITR liability. The common mistake: assuming TDS deducted on salary is sufficient when you also have freelance income or significant capital gains that weren't TDS-covered — and receiving an interest penalty notice under Section 234B months later.

Not collecting rent receipts before March 31 for HRA. If you claim HRA deduction and pay rent above Rs.8,333/month (Rs.1 lakh per year), you need rent receipts from your landlord. If you're claiming HRA via your employer's proof submission (January–February), receipts for April to March of the financial year are needed. Collecting receipts from a landlord after March 31 for the previous year is difficult and sometimes impossible. Ask your landlord for signed receipts monthly or at least quarterly.

Not checking Form 26AS for discrepancies before filing. The Annual Information Statement (AIS) on incometax.gov.in now shows every financial transaction reported to the tax department — bank interest credited, dividend received, property registrations, high-value cash transactions. If your ITR doesn't account for income reported in AIS, the system auto-matches and may flag a discrepancy requiring a response. Check AIS and Form 26AS before filing — not after — to ensure your return accounts for everything the department already knows about.

Old Regime vs New Regime: A Year-End Decision

Every financial year, salaried individuals can choose between the old tax regime (with deductions) and the new tax regime (lower slab rates, no deductions). The regime choice affects whether your year-end 80C investments, 80D payments, and home loan interest deductions are relevant at all.

For someone choosing the new regime, the 80C investments (ELSS, PPF top-up) are still worthwhile as long-term wealth builders — but they don't reduce your taxable income for that year. The March 31 urgency for tax-saving investments disappears under the new regime.

If you're unsure which regime to choose:

• Calculate your taxable income under both regimes
• Under the old regime: subtract all applicable deductions (80C, 80D, HRA, home loan interest)
• Compare the tax payable under each
• Choose the regime where total tax outflow is lower

For most individuals with a home loan, substantial 80C utilisation, and dependent parents with health insurance, the old regime often remains beneficial. For those without these deductions — no home loan, no dependents, simpler financial picture — the new regime's lower slabs typically result in lower tax.

The year-end checklist is most relevant to old-regime taxpayers. If you've opted for the new regime, your key year-end tasks are fewer: confirm your employer has the correct regime declaration, check advance tax if you have non-salary income, and verify Form 26AS before filing.
