Old Regime vs New Regime: Which Saves More Tax in 2025?
One of the most important decisions every taxpayer in India faces is choosing between the old and new income tax regimes. With the new regime becoming the default option from FY 2023-24, understanding the differences is crucial for optimizing your tax liability for FY 2024-25.
New Tax Regime Slabs for FY 2024-25 (AY 2025-26)
| Income Range | Tax Rate (New Regime) |
|---|---|
| Up to Rs 3,00,000 | Nil |
| Rs 3,00,001 to Rs 7,00,000 | 5% |
| Rs 7,00,001 to Rs 10,00,000 | 10% |
| Rs 10,00,001 to Rs 12,00,000 | 15% |
| Rs 12,00,001 to Rs 15,00,000 | 20% |
| Above Rs 15,00,000 | 30% |
Under the new regime, a standard deduction of Rs 75,000 is available for salaried employees and pensioners. A rebate under Section 87A ensures that individuals with taxable income up to Rs 7 lakh pay zero tax.
Old Tax Regime Slabs for FY 2024-25
| Income Range | Tax Rate (Old Regime) |
|---|---|
| Up to Rs 2,50,000 | Nil |
| Rs 2,50,001 to Rs 5,00,000 | 5% |
| Rs 5,00,001 to Rs 10,00,000 | 20% |
| Above Rs 10,00,000 | 30% |
The old regime offers a standard deduction of Rs 50,000 and allows you to claim numerous deductions and exemptions under Sections 80C, 80D, 24(b), HRA, and more.
Key Deductions Available Only Under Old Regime
- Section 80C – Up to Rs 1.5 lakh (PPF, ELSS, LIC, EPF, home loan principal)
- Section 80D – Health insurance premiums (Rs 25,000 to Rs 1 lakh depending on age)
- Section 24(b) – Home loan interest up to Rs 2 lakh for self-occupied property
- HRA Exemption – Based on rent paid, salary, and city of residence
- Section 80E – Education loan interest (no upper limit)
- Section 80G – Donations to specified funds and charities
- LTA – Leave Travel Allowance exemption
- Section 80CCD(1B) – Additional Rs 50,000 for NPS contribution
Deductions Allowed Under New Regime
The new regime allows very limited deductions:
- Standard deduction of Rs 75,000 for salaried individuals
- Employer contribution to NPS under Section 80CCD(2) up to 14% of salary
- Deduction for family pension under Section 57(iia)
- Deduction on voluntary retirement under Section 10(10C)
Comparison Example: Income of Rs 12 Lakh
Let us compare both regimes for a salaried individual earning Rs 12 lakh gross salary with common deductions:
| Particulars | Old Regime | New Regime |
|---|---|---|
| Gross Salary | Rs 12,00,000 | Rs 12,00,000 |
| Standard Deduction | Rs 50,000 | Rs 75,000 |
| Section 80C | Rs 1,50,000 | Not available |
| Section 80D | Rs 25,000 | Not available |
| NPS 80CCD(1B) | Rs 50,000 | Not available |
| Taxable Income | Rs 9,25,000 | Rs 11,25,000 |
| Tax Payable | Rs 85,800 | Rs 71,500 |
| Tax + 4% Cess | Rs 89,232 | Rs 74,360 |
In this scenario, the new regime saves Rs 14,872. However, if you add HRA exemption of Rs 1.5 lakh and home loan interest of Rs 2 lakh, the old regime may become more beneficial.
When is the Old Regime Better?
The old regime typically works better when your total deductions and exemptions exceed Rs 3.75 lakh. This is common for individuals who:
- Pay rent and claim HRA exemption
- Have an active home loan with significant interest payments
- Invest in PPF, ELSS, NPS, and have LIC premiums
- Pay health insurance for self and parents
When is the New Regime Better?
The new regime is better for individuals who:
- Do not have significant investments or deductions
- Live in their own house (no HRA claim)
- Have income below Rs 7 lakh (zero tax due to rebate)
- Prefer simplicity and do not want to maintain investment proofs
How to Switch Between Regimes
Salaried individuals can switch between regimes every year while filing their return. If you have business income, you can opt out of the new regime only once. The new regime is the default – you need to explicitly opt for the old regime.
