India Tax Season Timeline: Key Dates for FY 2025-26
| Date | Action Required |
|---|---|
| February 18, 2026 | Today — last 6 weeks to make tax-saving investments |
| March 15, 2026 | Advance tax Q4 installment (100% of annual liability) |
| March 28-29, 2026 | Last working days for ELSS, PPF contributions to count for FY 2025-26 |
| March 31, 2026 | Financial year closes — all 80C/80D investments must be complete |
| April 1, 2026 | FY 2026-27 begins, new tax regime settings apply |
| June 15, 2026 | Advance tax Q1 for FY 2026-27 (15% of estimated annual tax) |
| July 31, 2026 | ITR filing deadline for individuals (FY 2025-26) |
With only 6 weeks until year-end, the window for last-minute tax planning is narrow but still meaningful.
Advance Tax: Do You Need to Pay by March 15?
Advance tax applies when your total tax liability for the year exceeds ₹10,000 after accounting for TDS.
Who typically needs to pay advance tax:
- Freelancers and consultants with income not subject to TDS
- Salaried employees with significant interest income, rental income, or capital gains
- Business owners
- Investors with capital gains from stocks, mutual funds, or property sales
Who typically does NOT need to pay advance tax:
- Salaried employees whose entire tax is covered through employer TDS
- Senior citizens (60+) with no business income — they are exempt from advance tax
How to calculate your March 15 shortfall:
- Estimate your total income for FY 2025-26 (salary + other sources)
- Calculate tax on that income (use the Income Tax India calculator)
- Subtract TDS already deducted by your employer or banks
- If the remaining tax liability exceeds ₹10,000, that amount is due by March 15
Penalty for missing advance tax: Interest at 1% per month under Sections 234B and 234C from the due date. On a ₹50,000 shortfall, that is ₹500 per month — not catastrophic, but avoidable.
Last-Minute 80C Investments Before March 31
Under the old tax regime, Section 80C allows deductions up to ₹1.5 lakh. If you have not yet maximized it, here are your best options with 6 weeks remaining.
80C Options by Speed of Execution
| Investment | Time to Process | Returns | Lock-in |
|---|---|---|---|
| ELSS Mutual Fund | 1-2 business days | Market-linked (~12-15% historically) | 3 years |
| PPF Contribution | Instant (online) | 7.1% (guaranteed) | 15 years |
| NSC (National Savings Certificate) | Next day at post office | 7.7% | 5 years |
| Tax-Saving FD | Same day at bank | 6.5-7.5% | 5 years |
| Life Insurance Premium | Depends on policy | Varies | Policy term |
Recommended for most people: ELSS for highest returns with shortest lock-in (3 years). If you want guaranteed returns, PPF.
How much 80C is already used?
Check before investing more. Common 80C that may already be accounted for:
- EPF employee contribution (typically 12% of basic salary)
- Home loan principal repayment
- Children's school tuition fees (up to 2 children)
- Life insurance premiums you already pay
Many salaried employees with EPF contributions are closer to ₹1.5L than they realize. Check your Form 26AS or your salary slips before making additional investments.
Additional Deduction: NPS Section 80CCD(1B)
Over and above 80C, you can claim an additional ₹50,000 deduction by contributing to NPS (National Pension System) under Section 80CCD(1B). This is available under the old regime and is separate from the ₹1.5L 80C limit.
At the 30% tax bracket, this ₹50,000 NPS contribution saves an additional ₹15,600 in taxes.
New Regime vs Old Regime: Which Saves More?
The new tax regime is the default for FY 2025-26. Most taxpayers benefit from it — but not all.
New Tax Regime Slabs (FY 2025-26)
| Income Slab | Tax Rate |
|---|---|
| Up to ₹4 lakh | Nil |
| ₹4L - ₹8L | 5% |
| ₹8L - ₹12L | 10% |
| ₹12L - ₹16L | 15% |
| ₹16L - ₹20L | 20% |
| ₹20L - ₹24L | 25% |
| Above ₹24L | 30% |
Key benefit: Section 87A rebate means no tax is payable on income up to ₹12 lakh under the new regime. With the ₹75,000 standard deduction for salaried employees, the effective nil-tax limit is ₹12.75 lakh.
When the Old Regime Still Wins
The old regime makes sense if your total deductions are large enough to bring your taxable income significantly lower. Run this quick check:
Break-even calculation:
- Your annual income: ₹___
- HRA exemption (if applicable): ₹___
- 80C investments: ₹1,50,000 (max)
- 80D health insurance: ₹25,000-₹75,000
- Home loan interest (Section 24b): up to ₹2,00,000
- NPS 80CCD(1B): ₹50,000
- Total deductions: ₹___
If total deductions exceed roughly ₹3.75 lakh (for someone earning ₹15L), the old regime typically saves more. Below that threshold, the new regime usually wins.
Practical rule of thumb:
- Income up to ₹12L → New regime (no tax either way)
- Income ₹12L-₹15L with basic investments → New regime usually better
- Income above ₹15L with maxed 80C + HRA + home loan → Calculate both
Use the official Income Tax India calculator at incometax.gov.in to compare both regimes with your exact numbers.
Section 80D, 80G, and Other Deductions
These deductions apply only under the old tax regime.
Section 80D: Health Insurance
| Who is insured | Maximum deduction |
|---|---|
| Self, spouse, dependent children | ₹25,000 |
| Parents below 60 | ₹25,000 additional |
| Parents aged 60 or above | ₹50,000 additional |
| Maximum total | ₹75,000 |
If you pay health insurance premiums for yourself and senior citizen parents, you can claim up to ₹75,000 — saving ₹23,400 in taxes at the 30% bracket.
Note: Premiums must be paid by any mode other than cash to be eligible for deduction.
Section 80G: Charitable Donations
Donations to approved charitable organizations are deductible — 50% or 100% of the donated amount depending on the organization. PM CARES Fund, National Defense Fund, and certain NGOs qualify for 100% deduction. Keep your donation receipts with the organization's 80G registration number.
Section 80E: Education Loan Interest
Interest paid on education loans is fully deductible for up to 8 years. No upper limit. This applies to loans for higher education for yourself, spouse, or children. The deduction begins in the year you start repaying.
How to Budget for Tax Payments
For Salaried Employees
Your employer deducts TDS monthly. But you may have additional tax liability from:
- Fixed deposit interest
- Savings account interest above ₹10,000
- Capital gains from selling stocks or mutual funds
- Rental income
Action: In February and March, check your total other income and estimate if you have a shortfall. Use the Income Tax India portal to view Form 26AS and check all TDS already credited.
For Freelancers and Self-Employed
Set up a dedicated tax savings account and transfer a fixed percentage of every payment received:
| Income level | Suggested tax reserve |
|---|---|
| Up to ₹10L annual | 20% of each payment |
| ₹10L - ₹20L annual | 25-28% of each payment |
| Above ₹20L annual | 28-32% of each payment |
This prevents the March scramble where you owe a large tax bill with no liquid funds to cover it.
Monthly budgeting for advance tax:
If your estimated annual tax is ₹1.2 lakh:
- Set aside ₹10,000 per month into a liquid fund or high-yield savings
- At March 15, you will have ₹1.1-1.2L ready
- The money earns returns in the interim (liquid funds yield ~7%)
Smart Ways to Use Your ITR Refund
A tax refund is not a windfall — it is your own money that the government held interest-free. Use it purposefully.
The Right Priority Order
1. Emergency fund first If your emergency fund is below 3 months of expenses, direct your refund here. This is your financial safety net and should be non-negotiable.

2. High-interest debt Credit card balances at 36-42% annually are costing you far more than any investment earns. If you have outstanding credit card debt, your refund should go here next.
3. Start or increase your SIP Use the refund to start a new SIP for the next financial year, or top up an existing one. A ₹30,000 refund invested as a lump sum in an index fund, assuming 12% annual returns, grows to approximately ₹1.6 lakh in 15 years.
4. PPF or NPS contribution Make an early contribution for FY 2026-27 (starting April 1). Early contributions to PPF earn interest from April 1, giving you the maximum benefit of compounding.
What not to do with your refund:
- Upgrade your phone, TV, or appliances (lifestyle inflation)
- Spend on a vacation you have not budgeted for
- Let it sit in a savings account earning 3-4% when better options exist

Common Tax Budgeting Mistakes to Avoid
1. March panic investing Rushing to make 80C investments in the last week of March leads to poor choices — low-return tax-saving FDs, unnecessary insurance policies, or ELSS investments made at market peaks. Plan your 80C investments throughout the year, ideally with monthly SIPs from April.
2. Ignoring the new vs old regime decision Many taxpayers default to the old regime out of habit. With the new regime now offering zero tax up to ₹12 lakh, recalculating each year is worth 30 minutes of your time.
3. Missing advance tax instalments If you have freelance income or capital gains, deferring all tax payment to ITR filing time means paying 1% monthly interest on the shortfall. Pay quarterly and avoid this.
4. Not pre-validating your bank account ITR refunds go only to pre-validated bank accounts linked to your PAN. If your bank account is not validated on the Income Tax portal, your refund will fail to credit. Verify this before filing.
5. Forgetting to account for capital gains Sold stocks, mutual funds, or property this year? Short-term capital gains (holding under 1 year for equity) are taxed at 20%. Long-term capital gains above ₹1.25 lakh (for equity) are taxed at 12.5%. These are often forgotten in tax planning and result in surprise bills.
6. Over-investing in tax-saving instruments Section 80C has a ₹1.5L cap. Investing ₹2L in ELSS does not give you ₹2L of deduction — only ₹1.5L. Know your EPF contributions before adding more.
Tax Planning Template
Use the monthly budget template to set aside tax savings throughout the year. Add these line items to your budget:
For salaried employees:
- 80C investments (ELSS SIP): ₹12,500/month = ₹1.5L in 12 months
- 80D health insurance premium: Budget monthly equivalent
- Emergency fund contribution: Until you reach 6 months of expenses
- NPS contribution (optional): ₹4,167/month = ₹50,000/year for 80CCD(1B)
For freelancers:
- Tax reserve account: 25% of every invoice payment
- Advance tax reminders: Set calendar alerts for June 15, Sept 15, Dec 15, Mar 15
- GST savings (if applicable): Separate from income tax reserve
The key principle: taxes should never be a surprise. When you budget for them monthly, the March deadline becomes a confirmation rather than a crisis.
Frequently Asked Questions
When is the advance tax deadline for FY 2025-26?
The final advance tax installment (100% of annual liability) is due March 15, 2026. If you miss this deadline, you pay 1% monthly interest on the shortfall under Section 234B and 234C. Salaried employees with only salary income typically do not need to pay advance tax as TDS covers it — but those with interest income, rental income, capital gains, or freelance earnings over ₹10,000 in tax liability must pay.
What is the last date to invest in 80C for FY 2025-26?
March 31, 2026 is the last date. This includes ELSS mutual funds, PPF contributions, life insurance premiums, NSC, tax-saving FDs, and home loan principal repayment. Do not wait until the last week — ELSS units take 2-3 business days to reflect, and PPF online transfers may have delays.
Should I choose the new or old tax regime in FY 2025-26?
For most salaried employees earning up to ₹12 lakh, the new tax regime is better — no tax is payable due to the Section 87A rebate. For those above ₹12 lakh with significant 80C, 80D, HRA, and home loan deductions, the old regime may save more. Calculate both scenarios before deciding.
How much can I save with 80C investments?
Section 80C allows deductions up to ₹1.5 lakh per year under the old tax regime. If you are in the 30% tax bracket, maximizing 80C saves ₹46,800 in taxes. In the 20% bracket, it saves ₹31,200. Under the new tax regime, 80C deductions are not available.
What should I do with my income tax refund?
Priority order: (1) Top up your emergency fund if below 3 months of expenses, (2) Pay off high-interest debt — credit cards at 36-42% annually cost more than any investment earns, (3) Start or increase your SIP for the new financial year, (4) Make lump-sum PPF contribution. Avoid lifestyle splurges — a refund is your own money returned, not a bonus.
When will I receive my ITR refund?
After filing and e-verifying your ITR, refunds are typically processed within 20-45 days. For FY 2025-26, the ITR deadline for individuals is July 31, 2026. File early (April-May) for a June-July refund. Refunds are credited to your pre-validated bank account linked to your PAN.
What is Section 80D and how much can I claim?
Section 80D covers health insurance premiums. Claim up to ₹25,000 for yourself, spouse, and dependent children. Add ₹25,000 more for parents below 60, or ₹50,000 for senior citizen parents. Maximum total: ₹75,000 if you pay for yourself plus senior citizen parents.
How do I budget for tax payments if I am a freelancer?
Set aside 25-30% of every invoice into a separate tax savings account. Pay advance tax quarterly — 15% by June 15, 45% cumulative by September 15, 75% by December 15, and 100% by March 15. This avoids a large tax bill at year end that disrupts your cash flow.
The window to act for FY 2025-26 is closing. With six weeks until March 31, there is still time to make 80C investments, pay advance tax, and plan your refund intelligently. Do not wait until the last week.
Start with the monthly budget template to set up your tax savings plan — and make FY 2026-27 the year you stop treating taxes as a surprise.
