Want to calculate your income tax under the Old Regime for FY 2024-25? Use our tax calculator with latest slabs, deductions & exemptions to save more. This expert guide simplifies everything for Indian taxpayers using Old Tax Regime.
Introduction
Understanding your income tax liability is essential for effective financial planning. In India, taxpayers currently have two options for computing their income tax: the new tax regime and the old tax regime. Among these, many individuals, especially salaried professionals and senior citizens, continue to prefer the old system due to its flexibility in claiming deductions and exemptions.
This is where the Old Tax Regime Income Tax Calculator becomes an essential tool. It simplifies complex calculations, allowing taxpayers to determine their liability based on income, deductions, and applicable exemptions—without the need for manual computation or expert assistance.
With the financial year 2024-25 underway, having an accurate tax calculation method is more important than ever. Whether you're planning investments under Section 80C or claiming HRA, this guide will walk you through how to utilize an old regime calculator effectively and optimize your tax savings.

Understanding the Old Tax Regime: Basics & Benefits
The old tax regime, introduced before the 2020 Union Budget, remains a widely used option for many Indian taxpayers. Unlike the new tax regime, which offers lower tax rates but no deductions, the old regime allows taxpayers to claim a wide range of deductions under various sections of the Income Tax Act.
Income Tax Slabs Under Old Tax Regime (FY 2024-25)
Here are the applicable income tax slabs for individuals below 60 years of age under the old regime for the assessment year 2025-26:
| Annual Income | Tax Rate |
|---|---|
| Up to ₹2.5 lakh | Nil |
| ₹2.5 lakh – ₹5 lakh | 5% |
| ₹5 lakh – ₹10 lakh | 20% |
| Above ₹10 lakh | 30% |
Note: Rebate under Section 87A is available for income up to ₹5 lakh, making the effective tax zero.
For senior citizens (aged 60 and above) and super senior citizens (aged 80 and above), the exemption limits are higher, i.e., ₹3 lakh and ₹5 lakh, respectively.
Why Taxpayers Still Choose the Old Tax Regime
Many individuals continue to opt for the old regime because:
- It allows deductions under Section 80C (up to ₹1.5 lakh), 80D (medical insurance), HRA, LTA, and more.
- Ideal for those who have home loans, insurance premiums, tuition fees, and other deductible expenses.
-
Offers flexibility to reduce taxable income significantly if planned well.
Key Differences Between Old and New Tax Regime
Choosing the right tax regime is not just about rates—it’s about what you can claim and save. The old tax regime encourages savings and investments by offering numerous exemptions and deductions, while the new regime focuses on ease of filing with lower slab rates and zero deductions.
Here's a quick comparison:
| Aspect | Old Tax Regime | New Tax Regime |
|---|---|---|
| Tax Slabs | Higher | Lower |
| Deductions & Exemptions | Allowed | Not Allowed |
| Ideal For | Taxpayers with multiple investments | Individuals with minimal deductions |
| Standard Deduction | ₹50,000 for salaried/pensioners | ₹50,000 available from FY 2023-24 onward |
| Section 80C, 80D, HRA, etc. | Applicable | Not Applicable |
If you're uncertain which one to choose, using an Old Tax Regime Income Tax Calculator can help you compare both regimes side by side based on your income and deductions. You can try trusted online platforms like HR Calcy or explore official guidelines provided on the Income Tax India Portal for deeper clarity (opens in a new tab).

List of Common Deductions Allowed Under the Old Tax Regime
One of the main benefits of using the Old Tax Regime Income Tax Calculator is the ability to estimate deductions accurately. Let’s explore the major tax-saving avenues you can claim:
1. Section 80C (Limit: ₹1.5 Lakh)
This is the most widely used section among taxpayers. Eligible investments and expenses include:
- Employee Provident Fund (EPF)
- Public Provident Fund (PPF)
- Life Insurance Premiums

- Actual rent paid minus 10% of basic salary
- 50% of basic salary (metro) or 40% (non-metro)

HRA is one of the most effective tools for salaried individuals to reduce taxable income under the old regime.

6. Section 80TTA / 80TTB

Real-Life Example: Old Tax Regime Income Tax Calculation (FY 2024-25)
To illustrate the power of using an Old Tax Regime Income Tax Calculator, let’s look at an example:
Case: Salaried Individual (Age: 35)
- Annual Gross Salary: ₹12,00,000
- HRA Received: ₹1,80,000
- Rent Paid: ₹15,000/month in Mumbai
- Section 80C Investments: ₹1,50,000
- Medical Insurance Premium (80D): ₹20,000
- Standard Deduction: ₹50,000
Step-by-step tax calculation:
- Gross Income = ₹12,00,000
- Less: Standard Deduction = ₹50,000
- Less: HRA Exemption = Approx. ₹1,60,000 (as per rules)
- Less: Section 80C = ₹1,50,000
- Less: Section 80D = ₹20,000
Net Taxable Income = ₹8,20,000
Using the Old Tax Regime Income Tax Calculator, the estimated tax payable after rebate under Section 87A and cess comes to approximately ₹63,960.
This shows how smart tax planning and using a reliable calculator can help you reduce your tax burden significantly.
Old vs New Tax Regime: A Detailed Comparison
One of the most common queries taxpayers face is whether they should opt for the old tax regime with deductions or go for the new tax regime with lower slab rates but no exemptions. This comparison is crucial and often the main reason people rely on an Old Tax Regime Income Tax Calculator—to make an informed choice.
Here’s a detailed comparison of both regimes:
1. Tax Slabs
| Income Slab (₹) | Old Tax Regime Rate | New Tax Regime Rate (FY 2024-25) |
|---|---|---|
| Up to ₹2.5 lakh | Nil | Nil |
| ₹2.5 – ₹5 lakh | 5% | 5% |
| ₹5 – ₹7.5 lakh | 20% | 10% |
| ₹7.5 – ₹10 lakh | 20% | 15% |
| ₹10 – ₹12.5 lakh | 30% | 20% |
| ₹12.5 – ₹15 lakh | 30% | 25% |
| Above ₹15 lakh | 30% | 30% |
Note: Under both regimes, a rebate under Section 87A is available for individuals with income up to ₹5 lakh in old regime and ₹7 lakh in the new regime.
2. Deductions and Exemptions
| Component | Old Regime | New Regime |
|---|---|---|
| Standard Deduction | Yes | No |
| HRA | Yes | No |
| Section 80C (PF, LIC, etc.) | Yes | No |
| Section 80D (Health Insurance) | Yes | No |
| LTA, Education Allowance | Yes | No |
This makes the Old Tax Regime Income Tax Calculator ideal for taxpayers who want to evaluate whether their total deductions are sufficient to make the old regime more beneficial.
Limitations of the Old Tax Regime
While the old regime offers significant deductions, it also has certain drawbacks that must be considered before finalising your income tax filing approach.
1. Complexity in Calculation
The old regime requires meticulous documentation of various exemptions and deductions, which can be confusing for first-time taxpayers. Without using a proper calculator, there's a higher chance of error or missed opportunities.
2. Higher Tax Slabs
For those who do not have sufficient deductions to claim, the tax liability under the old regime can be significantly higher than under the new regime.
3. Documentation Burden
Proofs of investment (like LIC premium receipts, rent agreements, etc.) must be submitted, especially if you're salaried and relying on your employer for tax deduction. Any lapse can result in excess tax deduction.
4. Not Ideal for High-Income Earners Without Deductions
Individuals earning high salaries but not investing in tax-saving instruments often find the new regime better suited, thanks to the simplified and lower slab structure.
However, if you are someone who invests consistently in tax-saving avenues, the old regime may still be more profitable—and this is where the Old Tax Regime Income Tax Calculator helps you make that judgment effectively.
Who Should Use the Old Tax Regime?
The old tax regime continues to benefit a specific segment of taxpayers who strategically plan their investments and expenses. You may want to stick with the old regime if:
1. You Claim Major Tax Deductions
If you claim deductions under multiple sections such as:
- Section 80C (e.g., EPF, PPF, ELSS)
- Section 80D (Health insurance)
- Section 24(b) (Home loan interest)
- HRA for rented accommodation
…then the old regime often results in lower tax outgo.
2. You Are a Pensioner or Salaried Individual
The standard deduction of ₹50,000 is a flat relief, available only under the old regime. This significantly reduces taxable income for pensioners and salaried professionals.
3. You Have Home Loan Repayments
If you are servicing a housing loan and availing deduction under Section 24(b) and principal under Section 80C, the old regime becomes more favorable.
4. You Avail Tax-free Allowances
Benefits such as LTA (Leave Travel Allowance), education allowance, food coupons, or reimbursements are exempt under the old regime, reducing your taxable income.
To evaluate your actual savings potential, it is strongly advised to use a dependable Old Tax Regime Income Tax Calculator. A comparison tool helps you understand which option suits your financial profile, lifestyle, and long-term planning.
For more clarity, you can also refer to this official CBIC resource on tax regimes (opens in a new tab), which outlines deductions and exemptions in detail.
