You just got your July salary slip. The tax deduction looks different. Your SIP redemption from last month will be taxed at a higher rate. And you have till March 31 to decide which tax regime saves you more money.
Three things changed at once. Let me walk you through each one — and give you a calculator to figure out your exact savings in two minutes.
Budget 2024 changed the rules on July 23. Three big shifts hit your wallet:
1. STCG on equity/MFs jumped from 15% to 20% — every short-term gain now costs more
2. LTCG on equity/MFs went from 10% to 12.5% — but the exemption rose from ₹1L to ₹1.25L
3. New tax regime became the default — with ₹75K standard deduction and ₹25K rebate (effectively tax-free up to ₹7.75L)
Most people don’t realize: the SIP you’ve been running for 5 years? It’s not taxed as one block. Each monthly instalment is a separate lot. Some are LTCG, some are STCG. The math changes completely post-Budget.
And the regime choice? It’s not “new is always better.” At ₹15L salary with a home loan and HRA, the old regime can save you over ₹1 lakh.
What Changed in Budget 2024 (Effective July 23, 2024)
| Asset | STCG (Old) | STCG (New) | LTCG (Old) | LTCG (New) | Exemption |
|---|---|---|---|---|---|
| Listed equity shares | 15% | 20% | 10% | 12.5% | ₹1.25L |
| Equity MFs (≥65% equity) | 15% | 20% | 10% | 12.5% | ₹1.25L |
| Listed debt instruments | Slab | Slab | 20% with indexation | 12.5% no indexation | None |
| Property (bought before Jul 23) | Slab | Slab | 20% with indexation | Lower of: 12.5% no indexation OR 20% with indexation | None |
- Grandfathering still works:* Units bought before Jan 31, 2018 use FMV on that date as cost basis. This applies lot-by-lot for SIPs.
- Indexation is gone* for everything — flat 12.5% LTCG without indexation. Exception: property bought before July 23, 2024 — you can compute tax both ways and pay the lower amount.
How SIP Taxation Actually Works (FIFO Method)
You invest ₹10,000/month for 24 months. At month 25, you redeem ₹2 lakh.
Each monthly instalment = separate lot with its own purchase date and NAV.
- FIFO = First In, First Out.* The earliest units are sold first.
| SIP Month | Units Bought | Holding at Redemption | Type | Tax Rate |
|---|---|---|---|---|
| Month 1-12 | 12 lots | >12 months | LTCG | 12.5% above ₹1.25L |
| Month 13-24 | 12 lots | <12 months | STCG | 20% |
Your single redemption creates a mixed bag of LTCG and STCG. The first 12 months’ units become LTCG and enjoy the ₹1.25L exemption. The recent 12 months get hit at 20%.
- Real example from Moneycontrol:* ₹50,000/month SIP for 60 months (₹30L invested), redeemed after 5 years.
- Pre-Budget tax: ₹77,456
- Post-Budget tax: ₹94,095 (21.5% increase)
- The jump comes mainly from STCG rate hike on recent instalments
The ₹1.25L LTCG Exemption Shield
This is your free pass. Every financial year, the first ₹1.25 lakh of LTCG on equity/equity MFs is tax-free.
- How to use it:* If your portfolio has unrealised gains, sell just enough each year to book ₹1.25L of LTCG. Pay zero tax. Your cost basis resets to the current NAV. Next year, do it again.
This is called gain harvesting. It’s legal. No wash sale rule in India — you can sell and rebuy the same fund the same day.
Tax-Loss Harvesting Post-Budget 2024
| Loss Type | Offsets | Tax Saved per ₹1L (Old) | Tax Saved per ₹1L (New) | Gain |
|---|---|---|---|---|
| STCL (short-term) | STCG + LTCG | ₹15,000 | ₹20,000 | +33% |
| LTCL (long-term) | LTCG only | ₹10,000 | ₹12,500 | +25% |
- Rules:*
- STCL can offset both STCG and LTCG
- LTCL offsets only LTCG
- Carry forward 8 years (must file ITR on time)
- No wash sale rule — instant rebuy allowed
- Losses are set off first, then the ₹1.25L exemption applies to net LTCG
- Strategy:* Higher STCG rate (20%) makes short-term loss harvesting 33% more valuable. Every ₹1L of STCL harvested saves ₹20K now vs ₹15K pre-Budget.

The 3-Question Decision Framework
- Question 1: Is your gross income ≤ ₹7.75 lakh?*
- YES → New regime (zero tax due to rebate + standard deduction)
- NO → Go to Question 2
- Question 2: Do you have a home loan with interest >₹1.5L/year OR HRA >₹1.5L/year?*
- YES → Old regime (these two deductions alone often outweigh new regime slabs)
- NO → Go to Question 3
- Question 3: Can you claim ₹3.75L+ in total deductions (80C + 80D + NPS + HRA + 24b)?*
- YES → Old regime
- NO → New regime
- Quick reference:*
| Income | Deductions Available | Recommended |
|---|---|---|
| ≤ ₹7.75L | Any | New |
| ₹7.75L – ₹12L | < ₹3.75L | New |
| ₹7.75L – ₹12L | > ₹3.75L | Old |
| ₹12L – ₹15L | < ₹4.5L | New |
| ₹12L – ₹15L | > ₹4.5L | Old |
| ₹15L – ₹20L | < ₹5.5L | New |
| ₹15L – ₹20L | > ₹5.5L | Old |
| >₹50L | Any | Calculate (surcharge cap differs) |
Examples
Example 1: Rahul, ₹12L Salary, Renting, No Home Loan
- 80C: ₹1.5L (PPF + ELSS)
- 80D: ₹25K (health insurance)
- HRA: ₹1.8L
- Total deductions: ₹3.55L
- Verdict:* New regime saves ~₹9K. New regime taxable = ₹11.25L, tax = ~₹68.75K. Old regime taxable = ₹8.25L, tax = ~₹77.5K.
Example 2: Priya, ₹18L Salary, Home Loan ₹2.5L Interest, HRA ₹2L
- 80C: ₹1.5L
- 80D: ₹25K
- HRA: ₹2L
- Home loan 24(b): ₹2L
- Total deductions: ₹5.75L
- Verdict:* Old regime. Deductions (₹5.75L) > ₹5.5L breakeven at this income. Old saves ~₹85K.
Example 3: Amit, ₹8L Salary, Just Started Career
- 80C: ₹50K (only EPF)
- No HRA, no home loan, no 80D
- Verdict:* New regime. Zero tax. Old regime would charge ~₹23K.
Action Steps: Do This Before March 31
For Capital Gains
1. Check your portfolio — identify funds/stocks with unrealised LTCG >₹1.25L
2. Harvest gains — sell enough to book exactly ₹1.25L LTCG this FY. Rebuy immediately. Cost basis resets.
3. Harvest losses — if you have STCL, use it to offset STCG (saves 20% per rupee). LTCL offsets LTCG (saves 12.5%).
4. Review SIP redemptions — if you redeemed post-July 23, your tax is higher. Factor this in advance tax.
For Regime Choice
1. Download the calculator sheet — plug in your salary, 80C, 80D, HRA, home loan interest
2. Compare both regimes — the sheet auto-calculates tax for old vs new
3. Submit Form 10-IEA (if choosing old regime with business income) or just select in ITR (salaried can switch annually)
4. Tell your HR — so TDS is deducted correctly from next month
Quick Checklist
☐ Calculated LTCG/STCG for FY25 so far
☐ Booked ₹1.25L gain harvesting if eligible
☐ Harvested losses to offset gains
☐ Ran old vs new regime calculator with actual numbers
☐ Decided regime and informed HR/payroll
☐ Paid advance tax if capital gains pushed you over threshold
Key Takeaway
- Two minutes with a calculator saves you lakhs.*
The Budget 2024 changes aren’t just headline numbers — they change how your SIP redemptions are taxed (FIFO creates mixed STCG/LTCG), make loss harvesting 33% more valuable, and flip the regime decision for anyone with a home loan or high HRA.
- Do this today:* Open the calculator. Plug in your numbers. Pick the regime. Tell HR. Harvest ₹1.25L gains before March 31.
Your future self will thank you when the tax notice doesn’t arrive.
Risks & Limitations
- Tax laws can change via Finance Act amendments
- SIP FIFO examples assume consistent monthly investment — lump sums change the math
- Grandfathering calculations need exact Jan 31, 2018 NAV — verify with AMC statement
- Regime choice for business income requires Form 10-IEA (once filed, can’t switch back easily)
- Advance tax liability triggers if total tax >₹10K — capital gains count
- This is educational, not tax advice. Consult a CA for your specific situation
