How to Calculate Advance Tax: Simple Guide

taxpayers find it confusing. Whether you are salaried, self-employed, or earning multiple income streams, understanding how to calculate advance tax helps you avoid penalties and manage your finances better. 

Step 1: Estimate Your Total Income for the Year

Include all income sources:

• Salary (minus standard deduction)
   
• Freelance/professional income
   
• Business income
   
• Rental income
   
• Capital gains (if predictable)
   
• Interest income (FD, savings, bonds)
   
• Other taxable income

Step 2: Subtract Deductions

Reduce income using:

• Section 80C (PF, PPF, ELSS, etc.)
   
• 80D (medical insurance)
   
• 80G (donations)
   
• Other eligible deductions

This gives your taxable income.

Step 3: Apply Income Tax Slab Rates

Use the old or new tax regime based on your choice.
Compute the tax using the correct slab.

Add applicable:

• Health & Education Cess (4%)
   
• Surcharge (if applicable)

Step 4: Subtract TDS

Deduct all TDS already deducted on salary, bank interest, rent, etc.
If the remaining tax > ₹10,000, advance tax is mandatory.

Step 5: Pay as Per the Instalment Deadlines

Individuals must follow this schedule:

• 15 June – 15%
   
• 15 September – 45%
   
• 15 December – 75%
   
• 15 March – 100%

Payments can be made via Income Tax Portal → e-Pay Tax or Challan 280.

Example

If your total tax is ₹60,000 and TDS is ₹20,000, your advance tax payable is ₹40,000. You must pay this across the instalment deadlines.

Conclusion,

Calculating advance tax becomes simple once you estimate your annual income, apply the correct tax regime, subtract TDS, and follow the instalment schedule. Understanding how to calculate advance tax helps you avoid penalties, stay compliant, and spread your tax payment across the year. With a clear breakdown and timely payments, managing advance tax becomes straightforward for any taxpayer.
