Comprehensive Guide: How to Calculate Income Tax on Salary in India (2024-25)
Module A: Introduction & Importance of Income Tax Calculation
Income tax calculation on salary in India is a critical financial exercise that every salaried individual must perform annually. The Indian Income Tax Act, 1961, governs how taxes are levied on different income sources, with salary income being the most common for working professionals. Understanding how to calculate income tax on salary helps in:
- Financial Planning: Accurate tax calculation allows for better budgeting and investment planning throughout the financial year.
- Tax Optimization: Knowing your tax liability helps in utilizing available deductions and exemptions effectively to minimize tax outgo.
- Compliance: Proper calculation ensures compliance with tax laws, avoiding penalties or notices from the Income Tax Department.
- Informed Decisions: Helps in making informed choices between the old and new tax regimes based on your specific financial situation.
- Salary Negotiation: Understanding tax implications can be crucial during job changes or salary negotiations.
The Union Budget 2023 introduced significant changes to the tax structure, making the new tax regime the default option while still allowing taxpayers to opt for the old regime. This dual-system approach requires careful evaluation to determine which regime offers better tax savings for your specific income level and deduction claims.
Important: The financial year in India runs from April 1 to March 31, while the assessment year (when you file returns) is the following year. For example, FY 2024-25 corresponds to AY 2025-26.

How does the new tax regime’s standard deduction work? +
The standard deduction was introduced in the new tax regime in Budget 2023 to make it more attractive. Here’s how it works:

- Eligibility: Available to both salaried and pensioners
- Automatic Application: No need to submit any proofs

How It’s Calculated:
Taxable Income = (Gross Salary) – (Standard Deduction of ₹50,000)
Example Calculation:
For an employee with ₹10,00,000 annual salary:
- Gross Income: ₹10,00,000
- Less: Standard Deduction: ₹50,000

Before 2018, employees could claim:
- Transport allowance: ₹1,600/month (₹19,200/year)
- Medical reimbursement: ₹15,000/year

The standard deduction of ₹50,000 is more beneficial than the previous combined exemptions.
Special Cases:
- Pensioners: Can claim standard deduction on pension income
- Multiple Employers: Only one standard deduction allowed per year

Note: The standard deduction cannot be claimed if you’re opting for the presumptive taxation scheme under Section 44AD, 44ADA, or 44AE.
