Calculate taxes under New and Old Regimes (FY 2024-25)
What is Income Tax and Its Importance
Income Tax is a direct tax that a government levies on the income of its citizens and businesses. In India, the authority responsible for collecting this tax is the Central Board of Direct Taxes (CBDT). It is the primary source of revenue for the government, funding essential public services like infrastructure development, healthcare, education, defense, and social welfare schemes.
Paying income tax is not just a legal obligation but a contribution to nation-building. Every salaried individual, freelancer, or business owner whose income exceeds the basic exemption limit must file an Income Tax Return (ITR) annually. Failing to do so can lead to penalties and legal scrutiny. Understanding how your tax is calculated empowers you to plan your finances better and legally reduce your tax liability.
How Income Tax Works in India
The Indian tax system follows a progressive structure, meaning higher income attracts a higher tax rate. Tax is calculated on your net taxable income for a specific Financial Year (FY), which runs from April 1st to March 31st of the next year. The year in which you file the return for that income is called the Assessment Year (AY).
For example, for the income earned between April 1, 2024, and March 31, 2025 (FY 2024-25), the assessment year is AY 2025-26. The government releases budget updates annually, often tweaking tax slabs or deduction limits to provide relief or adjust for inflation.
Old vs New Tax Regime Explained
Currently, Indian taxpayers can choose between two tax regimes. Making the right choice is crucial for saving money.
The Old Regime: This traditional system allows you to claim various exemptions and deductions (like HRA, LTA, 80C, 80D). However, the tax rates in the higher income slabs are steeper. It is beneficial for those who have significant investments in tax-saving instruments and high expenses like rent and education loans.
The New Regime: Introduced to simplify the tax structure, this regime offers significantly lower tax rates but removes most exemptions and deductions (except Standard Deduction and NPS contribution under 80CCD(2)). It is the default regime now and is generally beneficial for those who do not want to lock their money in specific tax-saving schemes.
Understanding Tax Slabs and Rates
Under the New Tax Regime (FY 2024-25), the slabs are structured as follows:
- Up to ₹3 Lakhs: Nil (0% Tax)
- ₹3 Lakhs to ₹7 Lakhs: 5%
- ₹7 Lakhs to ₹10 Lakhs: 10%
- ₹10 Lakhs to ₹12 Lakhs: 15%
- ₹12 Lakhs to ₹15 Lakhs: 20%
- Above ₹15 Lakhs: 30%
Note: A tax rebate under Section 87A makes income up to ₹7 Lakhs effectively tax-free in the New Regime.
The Old Regime slabs depend on age. For individuals below 60, income up to ₹2.5 Lakhs is exempt. Between ₹2.5L-5L is 5%, ₹5L-10L is 20%, and above ₹10L is 30%.
How to Calculate Taxable Income
Taxable income is not your Gross Salary (CTC). It is derived after subtracting eligible components:
- Gross Income: Salary + Interest Income + Rental Income + Capital Gains.
- Less Exemptions (Old Regime only): HRA (House Rent Allowance), LTA (Leave Travel Allowance).
- Less Standard Deduction: A flat deduction allowed to salaried employees (₹50,000 in Old Regime; increased to ₹75,000 in New Regime for FY 24-25).
- Less Deductions: Investments under Chapter VI-A (80C, 80D, etc.).
- Net Taxable Income: The final figure on which tax rates are applied.
Common Deductions under Section 80C, 80D etc.
These are the most powerful tools to reduce tax liability in the Old Regime:
- Section 80C: Allows deduction up to ₹1.5 Lakhs. Includes EPF, PPF, ELSS Mutual Funds, LIC Premiums, Principal repayment of Home Loan, and Tuition fees for children.
- Section 80D: Deduction for Health Insurance premiums. Up to ₹25,000 for self/family and additional ₹25,000 (or ₹50,000 for seniors) for parents.
- Section 80E: Interest paid on Education Loan is fully deductible without any upper limit.
- Section 24(b): Interest on Home Loan up to ₹2 Lakhs can be claimed as a loss from house property.
Tips to Save Income Tax Legally
Tax planning should begin at the start of the financial year, not in March. Here are smart ways to save:
- Invest in ELSS: Equity Linked Savings Schemes offer the shortest lock-in period (3 years) among 80C options and potential for high returns.
- NPS (National Pension System): Apart from the ₹1.5L limit of 80C, you can claim an additional ₹50,000 under Section 80CCD(1B).
- Health Insurance: Buying insurance protects your health and your wallet via Section 80D.
- Donations: Contributions to valid charitable funds can grant 50% or 100% deduction under Section 80G.
How Age and Senior Citizen Status Affect Tax
The Income Tax department provides relief to older citizens, acknowledging their reduced earning capacity. In the Old Regime, the basic exemption limit is higher:
- General Citizens (<60 years): Exempt up to ₹2.5 Lakhs.
- Senior Citizens (60-80 years): Exempt up to ₹3 Lakhs.
- Super Senior Citizens (>80 years): Exempt up to ₹5 Lakhs.
Additionally, seniors get higher interest income deduction limits (up to ₹50,000 under Section 80TTB) compared to regular citizens.
Examples of Income Tax Calculation
Scenario 1: Income ₹8 Lakhs (Salaried, New Regime)
Gross Income: ₹8,00,000
Less Standard Deduction: ₹75,000
Net Taxable Income: ₹7,25,000
Tax Calculation:
– 0 to 3L: Nil
– 3L to 7L (5% on 4L): ₹20,000
– 7L to 7.25L (10% on 25k): ₹2,500
Total Tax: ₹22,500 + 4% Cess = ₹23,400.
Scenario 2: Income ₹15 Lakhs (Old Regime with Deductions)
Gross Income: ₹15,00,000
Less Standard Deduction: ₹50,000
Less 80C: ₹1,50,000 | Less 80D: ₹25,000 | Less HRA: ₹1,00,000
Net Taxable Income: ₹11,75,000.
Tax applies on this reduced amount according to old slabs.
