Illustrations showing the Best Tax Regime under Different situations
Below are a few illustrations explaining the situations wherein the new and old regimes are better in terms of tax outflow.
Example 1: New Regime Advantage in Tax Outflow (FY 2024-25)
| Income | Amount (Rs) | Old regime (Rs) | New regime (Rs) |
| Salary | 12,50,000 | 12,50,000 | 12,50,000 |
| Less: Standard deduction | 50,000 | 50,000 | 75,000 |
| Less: Professional tax | 2,400 | 2,400 | – |
| Gross total income | 11,97,600 | 11,97,600 | 11,75,000 |
| Less: Deduction u/s 80C | 1,50,000 | 1,50,000 | – |
| Total income | 10,47,600 | 10,47,600 | 11,75,000 |
| Income tax (Including 4% cess) | 1,31,851 | 79,300 |
In the above example, for an income of Rs 12.5 lakhs, the new tax regime is significantly beneficial by Rs 52,551. However, if you claim further deductions for interest on housing loan for SOP, health insurance, investment in NPS, education loans and so on, the old regime will be helpful in respect of tax savings.
Example 2: Where the old regime is better in respect of tax outflow (FY 2024-25)
| Income | Old regime (Rs) | New regime (Rs) |
| Salary | 10,00,000 | 10,00,000 |
| Less: HRA Exemption | 70,000 | – |
| Less: Standard deduction | 50,000 | 75,000 |
| Less: Professional tax | 2,400 | – |
| Gross total income | 8,77,600 | 9,25,000 |
| Less: Deduction u/s 80C | 1,50,000 | – |
| Less: Deduction u/s 80D | 50,000 | – |
| Total income | 6,77,600 | 9,25,000 |
| Income tax | 48,020 | 42,500 |
| Add: Education cess @ 4% | 1,921 | 1,700 |
| Total tax | 49,941 | 44,200 |
In Example 2, for an income of Rs 10 lakh having HRA exemption and 80D deduction, the old tax regime is beneficial by Rs 5,741.
If an individual claims lower deductions for tax savings towards health insurance, investment in NPS and so on, the new regime will be more beneficial against individuals who utilize the tax-saving investments.
Also, individuals with an income bracket between Rs 5-15 lakh with lower deductions claims will benefit from the new regime. In contrast, individuals can benefit more from the old regime by making tax-saving investments.
The tax payable under both the new and the old regimes without claiming deductions and exemptions for FY 2024-25 (AY 2025-26) is as below:
| Annual income* | Tax under the old regime (Rs) (A) | Tax under the new regime (Rs) (B) | Tax savings under the new regime (Rs) (A – B) |
| Rs 7,50,000 | 54,600 | 0 | 54,600 |
| Rs 10,00,000 | 1,06,600 | 44,200 | 62,400 |
| Rs 12,50,000 | 1,79,400 | 79,300 | 1,00,100 |
| Rs 15,00,000 | 2,57,400 | 1,30,000 | 1,27,400 |
*Assumed that the annual income is after reducing the standard deduction under both old and new regimes.
The above table shows that the new tax regime generally saves taxes for taxpayers who don’t claim any deductions or exemptions.
Treatment of House Property Deductions and Business Losses Under the New Tax Regime
| Deduction / Loss claimed | Old Regime | New Regime |
| Self-Occupied House Property | Interest on housing loan up to ₹2 lakh deductible; loss can be set off. | No deduction for interest; no set-off of loss. |
