Whenever tax season comes around, one of the most searched terms is “old regime tax slab”. And it makes sense as many taxpayers are still more comfortable with the old regime, which allows them to claim deductions and exemptions to lower their taxable income.
But here’s the confusion: with the new tax regime becoming default from FY 2025–26, people often wonder what the slabs under the old regime are and whether they can still choose it. Don’t worry! This article will clear things up in simple terms.
What is the old regime tax slab?
The old regime tax slab refers to the income ranges and their corresponding tax rates under the traditional tax system. Unlike the new regime, where rates are lower but deductions are limited, the old regime uses higher tax rates but allows you to reduce your taxable income through multiple deductions (like 80C, 80D, and home loan interest) and exemptions (like HRA and LTA).
For example:
- If your annual salary is ₹8 lakh, the slab rate under the old regime would be 20%.
- But if you claim deductions (say ₹1.5 lakh under 80C and ₹25,000 under 80D), your taxable income reduces to ₹6.25 lakh. That means your effective tax liability will be much lower than simply applying the slab rate.
👉 In short, the old regime tax slab is not just about the numbers—it’s about how well you use deductions to bring your taxable income down.
What are the old regime tax slabs for FY 2025–26?
Under the old tax regime, the income slabs are fewer and the tax rates are higher compared to the new regime. However, taxpayers get the benefit of multiple deductions and exemptions, which can significantly reduce their taxable income.
Here are the old regime tax slabs for FY 2025–26 (for individuals below 60 years):
| Annual Income | Tax Rate (Old Regime) |
| Up to ₹2,50,000 | Nil |
| ₹2,50,001 – ₹5,00,000 | 5% |
| ₹5,00,001 – ₹10,00,000 | 20% |
| Above ₹10,00,000 | 30% |
👉 If your income is up to ₹5 lakh, you can still claim the Section 87A rebate, which makes your total tax liability zero.
It’s important to note that these slabs have not changed with the introduction of the new regime. The old regime continues to exist as an option for taxpayers who prefer to save tax through exemptions like HRA and deductions like 80C, 80D, and 24(b) for home loan interest.
How does the old regime tax slab work with deductions?
The biggest advantage of the old regime tax slab is that you can reduce your taxable income by claiming deductions and exemptions. The slab rate may look high at first glance, but your actual tax liability can be much lower if you plan well.
Here’s how it works:
- Claim deductions under Section 80C
- Investments in PPF, ELSS, tax-saving FDs, life insurance premiums, etc.
- Maximum limit: ₹1.5 lakh.
- Investments in PPF, ELSS, tax-saving FDs, life insurance premiums, etc.
- Medical insurance under Section 80D
- Deduction for premiums paid for self, spouse, children, and parents.
- Maximum limit: ₹25,000 (₹50,000 for senior citizen parents).
- Deduction for premiums paid for self, spouse, children, and parents.
- Home loan interest under Section 24(b)
- Deduction up to ₹2 lakh on interest paid for a self-occupied property.
- Deduction up to ₹2 lakh on interest paid for a self-occupied property.
- Exemptions like HRA and LTA
- Salaried employees can claim House Rent Allowance (HRA) if they live in rented accommodation.
- Leave Travel Allowance (LTA) can be claimed for travel expenses within India.
- Salaried employees can claim House Rent Allowance (HRA) if they live in rented accommodation.
Example:
Suppose your annual income is ₹10 lakh.
- You invest ₹1.5 lakh under Section 80C,
- Pay ₹25,000 as medical insurance (80D), and
- Claim ₹2 lakh for home loan interest (24b).
Your taxable income reduces from ₹10 lakh to ₹6.25 lakh. This means you fall into a lower effective slab, saving a significant amount of tax.
👉 That’s why the old regime works best for people who actively use deductions to bring down their taxable income.
Who benefits the most from the old regime tax slabs?
The old regime is not for everyone. It works best for taxpayers who have a structured financial plan and regularly make use of deductions.
Here are the groups who benefit most:
- Salaried employees with HRA and LTA: If you’re living on rent and receive allowances, exemptions can reduce your taxable income a lot.
- Home loan borrowers: Deduction on interest payments makes the old regime very attractive.
- Families with insurance and medical expenses: Premiums paid for life insurance and health insurance give you useful deductions.
- Long-term savers and investors: If you already invest in PPF, NPS, ELSS, or other 80C instruments, you can maximise benefits under the old regime.
- High-income earners: Those with income above ₹12–15 lakh may still save more under the old regime compared to the new one—provided they use all available deductions.
👉 In simple words, the old regime tax slab rewards planners. If you’re organised and invest regularly, you’re likely to save more here than under the new regime.
What are the pros and cons of old regime tax slabs?
Like every tax system, the old regime tax slabs come with their strengths and weaknesses. Let’s simplify:
✅ Pros
- Multiple deductions and exemptions: You can claim benefits under Section 80C, 80D, HRA, LTA, home loan interest, and more.
- Encourages savings and investments: Tax benefits push people to invest in instruments like PPF, ELSS, and NPS, which also build long-term wealth.
- Beneficial for high earners: With careful planning, even those in the 30% bracket can reduce their taxable income significantly.
- Supports family expenses: Medical insurance, education loans, and housing-related expenses all get tax relief.
❌ Cons
- Higher tax rates: Compared to the new regime, the slab rates are steeper.
- Complex compliance: You need to maintain receipts, proofs, and submit investment details.
- Lower in-hand salary: Since a chunk of income goes into tax-saving investments, your immediate disposable income may be less.
- Not useful for non-investors: If you don’t use deductions, you may end up paying more tax than under the new regime.
👉 In short, the old regime tax slabs reward discipline but punish inaction.
Is the old regime tax slab still relevant in 2025?
Yes, the old regime tax slab remains relevant even though the new regime has become the default option from FY 2025–26.
Here’s why it still matters:
- Better for planners: If you already invest in tax-saving instruments and pay for insurance or housing, the old regime could still leave you with more post-tax savings.
- High-income advantage: For those earning above ₹12–15 lakh annually, the old regime may reduce tax liability more than the new regime if deductions are maximised.
- Encourages financial discipline: The structure of the old regime nudges taxpayers to build a habit of saving, which is crucial for long-term wealth and retirement planning.
👉 Even in 2025, the government continues to allow taxpayers to choose the old regime voluntarily while filing their ITR. So, while the new regime is simpler, the old one is still valuable for those who use its benefits smartly.
Conclusion
The old regime tax slabs may look tougher on paper with higher rates, but they can still help you save significantly if you know how to use deductions and exemptions. While the new regime offers simplicity and zero tax up to ₹12–12.75 lakh, the old regime continues to benefit planners—those who invest in PPF, ELSS, NPS, claim HRA, or pay insurance premiums and housing loan EMIs.
💡 Think of it this way: the new regime is for those who want simplicity, while the old regime is for those who want to maximise savings. The best choice is the one that matches your financial lifestyle and goals.
