Tax Planning Checklist
Month-by-month tax planning so you never scramble.
Every year, around February, Mathi does the same thing.
She opens her laptop. She stares at a blank notes app. She searches "how to save tax last minute." She reads three panicked articles. Then she transfers ₹40,000 to some random insurance plan she'll forget by July.
The insurance agent calls this "tax planning." Mathi's CA calls it "financial self-harm."
"You don't plan taxes in February," Priya told her. "You plan taxes in April. February is just execution, or panic, if you skipped April."
Mathi decided that this year would be different. This is the plan Priya gave her. Adapted here for anyone who has ever bought bad insurance in March just to get a tax receipt.
Why Panic-Buying in March Is Always Expensive
The process of legally arranging your finances throughout the year to minimise your tax liability, by maximising eligible deductions, choosing the right regime, and timing your investments appropriately. Not the same as last-minute scrambling in March.
The problem with February-March investing:
- You buy whatever's being marketed the hardest (usually products with high agent commissions)
- You don't compare options: you just need something with a tax receipt
- You lock money into plans you don't need (endowment, ULIP)
- You invest lump sum instead of systematically: higher risk, less discipline
- You miss the actual best investments because you're running out of time
The fix is simple: spread the actions across the year. Here's the full calendar.
APRIL: The New Year of Your Money Life
April 1 is the financial new year. The decisions you make in April determine your tax bill 12 months later. This is the highest-leverage month.
Action 1: Choose your tax regime
Tell your employer, in the investment declaration form that comes in April, whether you want old or new regime. Use the Income Tax Calculator to run the numbers on your current salary and expected deductions.
If you don't submit the regime choice to HR, you land in the new regime automatically. That might be fine, or it might cost you thousands. Know your choice before the deadline.
Action 2: Submit investment declaration to HR
This is where you declare what deductions you'll claim, HRA, 80C, 80D, home loan interest, so HR calculates the right TDS all year.
Mathi, as a freelancer, doesn't have an employer. But she should start keeping track of all her insurance premiums and expenses from April 1.
Action 3: Check last year's ITR for carryforward losses
Capital losses from selling stocks/mutual funds can be carried forward 8 years and set off against future capital gains. Mathi sold some debt MFs at a loss last year, her CA should have captured this in the ITR. Those losses can reduce tax on future gains.
April Checklist:
- Confirm regime choice (old vs new) ✓
- Submit HR declaration (if salaried) ✓
- Review last year's ITR for carryforward losses ✓
- Open NPS account if not yet done ✓
- Start ELSS SIP if going old regime ✓
MAY – SEPTEMBER: Mid-Year Maintenance
Nothing dramatic, but don't ignore these months.
May-June: Review Form 16 / AIS
Mathi receives no Form 16 (no employer). But she should check her AIS on the income tax portal. It shows all income sources the government knows about: bank interest, mutual fund redemptions, payments from companies (TDS deducted by clients).
Cross-check AIS with your own records. Discrepancies need to be fixed before you file ITR, not discovered after a notice.
July 31: File Your ITR
This is the most important deadline. File by July 31 for the previous financial year (FY 2024-25 → file by July 31, 2025).
File after July 31 (but before December 31) and you pay a ₹5,000 late filing fee. File after December 31, you probably can't file at all for that year unless you get an extension. Just file in July. It takes 30 minutes if your CA or an online tool handles it.
August-September: Advance Tax Check (Self-Employed)
If Mathi's estimated annual tax liability exceeds ₹10,000, she must pay advance tax in four instalments:
- June 15: 15% of annual tax
- September 15: 45% of annual tax
- December 15: 75% of annual tax
- March 15: 100% of annual tax
Salaried individuals mostly skip advance tax because TDS handles it. But Mathi gets freelance income without TDS, she needs to pay advance tax on that income.
Estimated annual income: ₹7,20,000 Estimated deductions: ₹25,000 standard + ₹40,000 80D + ₹50,000 NPS = ₹1,15,000 Taxable income: ₹6,05,000 Estimated tax (old regime): ~₹70,500
Advance tax schedule:
- By June 15: 15% = ₹10,575
- By September 15: 45% = ₹31,725 (cumulative)
- By December 15: 75% = ₹52,875 (cumulative)
- By March 15: 100% = ₹70,500 (cumulative)
Miss advance tax instalments → 1% simple interest per month on the shortfall under Section 234C. Small amounts but annoying. Pay on time.
Mid-Year Checklist:
- File ITR by July 31 ✓
- Pay advance tax instalments (self-employed) ✓
- Review AIS for any income discrepancies ✓
- Check if investment plans are on track (ELSS SIP running?) ✓
OCTOBER – DECEMBER: Year-End Strategy Begins
This is when smart people start, not when panicked people are done.
October-November: Portfolio Review
Check your equity investments. Which ones have been held 12+ months? Do any have gains near ₹1.25L? Consider tax harvesting, sell to book the LTCG within the ₹1.25L annual exemption, then rebuy.
Also review losses. If you have losing positions you've been holding hoping they'll recover, selling them before March 31 creates capital losses you can carry forward and offset against future gains.
December: Update HR Declaration
If your situation changed (new house loan, new insurance, rented a house this year), update your HR investment declaration. This adjusts TDS for the remaining months.
December Checklist:
- Tax harvesting review ✓
- Review capital loss positions ✓
- Update HR declaration if needed ✓
- Begin 80C top-up if not maxed yet ✓
JANUARY – MARCH: Final Execution (Not Panic)
If Mathi has done the April–December steps right, January-March is calm. Here's what remains:
January: Check 80C Status
Pull up the ELSS SIP statement. Add EPF contribution. Add insurance premiums. How close are you to ₹1.5L? If short, you have 90 days, plenty of time to invest the difference systematically.
The most expensive 80C mistake: buying a ₹1L ULIP or endowment policy in March to fill the limit. These products give 4-6% returns and lock you in for 10-20 years. If you need to fill 80C in February-March, buy ELSS (3-year lock-in, market returns, actual wealth creation).
January-February: Submit Actual Proofs to HR
Your employer will ask for investment proof, actual receipts, not just declarations. Submit:
- Rent receipts (with landlord PAN if rent > ₹8,333/month)
- Insurance premium receipts
- ELSS/PPF account statements
- Home loan interest certificate (if applicable)
Submit by the deadline HR gives you. Fail to submit proofs and HR will deduct higher TDS for January, February, March.
February: Second Advance Tax for Self-Employed
Double-check your advance tax payments are correct. If income changed significantly from estimates, adjust the March 15 payment.
March 31: The Real Deadline
For self-employed and others not relying on employer, March 31 is the last day for:
- Final advance tax payment (March 15 technically, but March 31 for some)
- 80C top-up investments (must be made before March 31 to count for this FY)
- ELSS lump sum (if doing one-time instead of SIP)
- NPS Tier 1 contribution (if using 80CCD(1B))
- Health check-up receipts to claim under 80D
An ELSS purchase on March 31, 2026 counts for FY 2025-26 (the year ending that day). The NAV date matters, ensure the transaction is processed before midnight March 31.
Mathi's Full-Year Planner
| Month | Action | Priority |
|---|---|---|

The One Habit That Fixes Everything
Mathi's CA Priya gives every client one piece of advice: start a ₹5,000/month ELSS SIP in April.
That's it. By March, the SIP will have invested ₹60,000 automatically. Add EPF (if salaried), insurance premiums, and NPS, most people are at or near ₹1.5L without a single panic purchase. The March madness becomes irrelevant.
Discipline in April > Panic in March. Every time.
Key Takeaways
- Tax planning starts April 1: that's when regime choice and HR declarations happen, not February
- File ITR by July 31 every year: missing it costs ₹5,000 and creates complications
- Self-employed must pay advance tax in four instalments (June, September, December, March)
- Tax harvesting in October-November can legally reduce future LTCG tax on equity investments
- Don't buy endowment/ULIP in March to fill 80C: use ELSS if you must invest at the last minute
- A ₹5,000/month ELSS SIP started in April eliminates most of the March panic
