For most salaried professionals in India, income tax is the single largest deduction from their paycheck, yet it often remains poorly understood. Terms like CTC, taxable income, deductions, exemptions, and tax regimes can feel overwhelming, especially when rules change almost every year. A clear understanding of income tax basics is no longer optional. It is essential for better financial planning, higher take-home pay, and stress-free compliance.
This article explains the fundamentals of income tax in India from a salaried employee’s perspective. It covers how salary is taxed, the difference between the old and new tax regimes, applicable tax slabs, key deductions, and practical tips to help you make informed decisions for the financial year 2025–26 and beyond.
What Is Income Tax and Why Do Salaried Employees Pay It?
Income tax is a direct tax levied by the Government of India on income earned by individuals and entities. For salaried employees, income tax is charged under the head “Income from Salaries” as defined in the Income Tax Act, 1961.
Your employer deducts tax at source every month, known as Tax Deducted at Source (TDS), and deposits it with the government. This TDS is an advance payment of your final tax liability, which is adjusted when you file your Income Tax Return (ITR).
Understanding Your Salary Structure
Before calculating tax, it is important to understand the components of salary:
- Cost to Company (CTC): The total cost incurred by the employer, including salary, bonuses, and employer contributions to provident fund and gratuity.
- Gross Salary: CTC minus employer contributions.
- Net or Take-Home Salary: Gross salary minus deductions such as TDS, employee provident fund, and professional tax.
- Taxable Income: Gross salary minus eligible exemptions and deductions.
Only taxable income is considered for calculating income tax.
Old Tax Regime vs New Tax Regime
Since the introduction of Section 115BAC, salaried employees can choose between two tax regimes.
New Tax Regime
The new tax regime is the default option for FY 2025–26. It offers lower tax rates and a simplified structure but allows very limited deductions and exemptions.
Key features:
- Basic exemption limit of ₹4 lakh.
- Standard deduction of ₹75,000 for salaried employees.
- Income up to ₹12 lakh effectively tax-free due to rebate under Section 87A.
- Most deductions such as HRA, 80C, and 80D are not allowed.
Old Tax Regime
The old tax regime allows multiple deductions and exemptions but applies higher tax rates.
Key features:
- Basic exemption limit of ₹2.5 lakh for individuals below 60 years.
- Standard deduction of ₹50,000.
- Allows deductions such as Section 80C, HRA, LTA, 80D, and home loan interest.
- Rebate under Section 87A for income up to ₹5 lakh.
Choosing the right regime depends on how many deductions you can claim.
Income Tax Slabs for Salaried Employees (FY 2025–26)
New Tax Regime Slabs
- Up to ₹4 lakh: Nil
- ₹4 lakh to ₹8 lakh: 5%
- ₹8 lakh to ₹12 lakh: 10%
- ₹12 lakh to ₹16 lakh: 15%
- ₹16 lakh to ₹20 lakh: 20%
- ₹20 lakh to ₹24 lakh: 25%
- Above ₹24 lakh: 30%
Old Tax Regime Slabs (Below 60 years)
- Up to ₹2.5 lakh: Nil
- ₹2.5 lakh to ₹5 lakh: 5%
- ₹5 lakh to ₹10 lakh: 20%
- Above ₹10 lakh: 30%
Health and education cess at 4% applies under both regimes.
Standard Deduction Explained
The standard deduction is a flat deduction available to salaried employees and pensioners without any proof or documentation.
- Old tax regime: ₹50,000
- New tax regime: ₹75,000
This deduction directly reduces taxable salary and is one of the most important benefits for salaried individuals.
Key Deductions Under the Old Tax Regime
If you opt for the old regime, the following deductions can significantly reduce your tax liability:
- Section 80C: Up to ₹1.5 lakh for investments such as EPF, PPF, ELSS, life insurance, and tuition fees.
- Section 80D: Health insurance premiums for self and family.
- House Rent Allowance (HRA): Partial exemption for those living in rented accommodation.
- Section 24(b): Interest on home loan for self-occupied property.
- Section 80CCD(1B): Additional ₹50,000 for NPS contributions.
These deductions are not available under the new tax regime.
How to Choose Between Old and New Tax Regime
A simple rule of thumb:
- Choose the new regime if you have limited deductions and prefer simplicity.
- Choose the old regime if your total deductions exceed approximately ₹3 to ₹3.5 lakh.
Always calculate tax under both regimes before filing your return to identify the more beneficial option.
Filing Income Tax Returns
Even if your employer deducts TDS, filing an ITR is important because:
- It allows you to claim refunds if excess tax was deducted.
- It acts as income proof for loans and visas.
- It ensures compliance and avoids penalties.
For most salaried employees, ITR-1 or ITR-2 is sufficient depending on income sources.
Conclusion
Understanding income tax basics empowers salaried employees to take control of their finances. With the availability of two tax regimes, higher standard deductions, and revised slabs, informed decision-making can lead to significant tax savings and better cash flow. Instead of viewing tax as a burden, consider it a planning opportunity.
The right knowledge, combined with timely tax planning, can help you maximize take-home pay while staying fully compliant with the law.
