New Tax Regime Slabs — FY 2024-25 (AY 2025-26)
The New Tax Regime slabs for FY 2024-25 are based on the Finance Act 2023 with the Budget 2024 revision. Note that these are different from the significantly revised slabs introduced in Budget 2025 for FY 2025-26.
| Total Income Slab | Tax Rate | Tax on This Slab |
|---|---|---|
| Up to ₹3,00,000 | Nil | ₹0 |
| ₹3,00,001 to ₹7,00,000 | 5% | Up to ₹20,000 |
| ₹7,00,001 to ₹10,00,000 | 10% | Up to ₹30,000 |
| ₹10,00,001 to ₹12,00,000 | 15% | Up to ₹30,000 |
| ₹12,00,001 to ₹15,00,000 | 20% | Up to ₹60,000 |
| Above ₹15,00,000 | 30% | 30% on amount exceeding ₹15L |
Key points for FY 2024-25 New Regime:
✅ Standard Deduction of ₹75,000 for salaried individuals (revised upward from ₹50,000 in Budget 2024)
✅ Section 87A Rebate of up to ₹25,000 — zero tax for income up to ₹7,00,000
✅ Effective zero tax for salaried individuals earning up to ₹7,75,000 gross after Standard Deduction
✅ Marginal relief available for income between ₹7,00,000 and ₹7,75,000
⚠️ These slabs are less generous than FY 2025-26 — Budget 2025 significantly improved the New Regime
Old Tax Regime — Slabs for FY 2024-25
The Old Tax Regime slabs for FY 2024-25 are identical to FY 2025-26 — no changes were made. The regime continues to offer all deductions under Chapter VI-A.
| Income Slab | Below 60 Years | Senior (60-79 Yrs) | Super Senior (80+ Yrs) |
|---|---|---|---|
| Up to ₹2,50,000 | Nil | — | — |
| Up to ₹3,00,000 | — | Nil | — |
| Up to ₹5,00,000 | — | — | Nil |
| ₹2.5L to ₹5,00,000 | 5% | 5% | — |
| ₹5,00,001 to ₹10,00,000 | 20% | 20% | 20% |
| Above ₹10,00,000 | 30% | 30% | 30% |
⚠️ Old Regime 87A Note for FY 2024-25: Rebate of ₹12,500 available only if total income does not exceed ₹5,00,000. A CBDT clarification issued in July 2024 confirmed that the rebate is NOT available against Special Rate Capital Gains tax (STCG 111A and LTCG 112A) even if total income is below ₹5 lakh. This caused significant confusion during the FY 2024-25 filing season — our calculator correctly implements this rule.
Capital Gains Tax Rates — FY 2024-25
Budget 2024 (effective 23rd July 2024) made significant changes to capital gains taxation. The revised rates apply to all transactions from 23rd July 2024 onwards. Transactions before this date follow the earlier rates.
| Type of Capital Gain | Rate Before 23 Jul 2024 | Rate From 23 Jul 2024 | Exemption |
|---|---|---|---|
| STCG u/s 111A (Listed Equity) | 15% | 20% | None |
| LTCG u/s 112A (Listed Equity) | 10% | 12.5% | ₹1,00,000 (pre-23 Jul) / ₹1,25,000 (post-23 Jul) |
| Normal LTCG u/s 112 | 20% with indexation | 12.5% without indexation | None |
| Normal STCG (Slab) | Slab Rate | Slab Rate | None |
⚠️ Important for Property Sellers: For immovable property sold before 23rd July 2024, taxpayers have a one-time option to choose between the old rate (20% with indexation) or the new rate (12.5% without indexation) — whichever is lower. This option is only available for property acquired before 23rd July 2024. Our calculator uses the post-23 July 2024 rates — for pre-July transactions, consult a CA for the correct computation.
Old vs New Regime for FY 2024-25 — Key Differences
The regime comparison for FY 2024-25 is different from FY 2025-26 because the New Regime slabs were less generous before Budget 2025. Here is what changed and what it means for your tax planning:
New Regime FY 2024-25
- Zero tax up to ₹7,00,000 income
- Zero tax up to ₹7,75,000 for salaried (after ₹75,000 Standard Deduction)
- No deductions under 80C, 80D, HRA
- No home loan interest set-off
- Marginal relief at ₹7,00,000 boundary
Old Regime FY 2024-25
- Zero tax up to ₹5,00,000 after 87A rebate
- Full 80C deduction of ₹1,50,000 available
- HRA exemption available
- Home loan interest set-off up to ₹2,00,000
- Standard Deduction of ₹50,000
CA Insight: For FY 2024-25 specifically, many taxpayers who were on the fence between regimes found the Old Regime more beneficial — especially those with home loans, HRA and full 80C utilisation. The New Regime became significantly more attractive only from FY 2025-26 after Budget 2025 revised the slabs. If you are filing a belated return for FY 2024-25, it is worth computing your liability under both regimes using this calculator before choosing.
Interest Under Sections 234A, 234B and 234C — Critical for Belated Filers
If you are filing your FY 2024-25 ITR after 31st July 2025, interest under Section 234A will apply on the balance tax payable. Here is what you need to know:
| Section | Trigger | Rate | Computed On |
|---|---|---|---|
| 234A | Filing after 31st July 2025 | 1% per month or part thereof | Balance tax after TDS and advance tax |
| 234B | Advance tax paid less than 90% of assessed tax | 1% per month | Assessed tax minus advance tax paid |
| 234C | Quarterly advance tax shortfall | 1% per month | Shortfall per quarter |
To calculate your exact interest liability — expand the “Taxes Paid, TDS/TCS & Interest” section in the calculator above, enter your TDS deducted from Form 26AS, enter any advance tax paid quarter-wise, and enter your actual filing date. The calculator will compute the precise interest amounts under all three sections automatically.
