Learn how advance tax works, including eligibility, due dates, calculation steps, and how payments are made during the financial year.

Last updated on: Apr 29, 2026

Advance tax is the income tax payable by individuals who earn from other sources along with their salary. It is paid in instalments during the financial year instead of a lump sum at the end. It applies when the total tax liability exceeds a specified threshold and helps align tax payments with income earned across the year. Rent, capital gains from shares, fixed deposits, lottery, etc. are a few examples of income sources covered under advance taxation. 

Overview of Advance Tax

Advance tax is applicable to individuals, professionals, businesses, and companies whose estimated tax liability, after adjusting for TDS or TCS, exceeds ₹10,000 in a financial year.

Income sources that may lead to advance tax liability include:

  • Salary with insufficient TDS: When employer deductions do not fully cover tax liability

  • Business or professional income: Earnings from self-employment or business activities

  • Capital gains: Profits from sale of shares or other assets

  • Interest income: Earnings from fixed deposits or savings instruments

  • Rental income: Income generated from house property

  • Other income: Such as lottery winnings or casual income

Advance tax ensures that tax payments are spread throughout the year rather than concentrated at year-end. 

Who Should Pay Advance Tax

Advance tax liability depends on the level and nature of income earned during the year:

  • Tax liability threshold: Applicable if total tax payable after TDS/TCS exceeds ₹10,000

  • Salaried individuals: Required if TDS deducted by employer is not sufficient

  • Self-employed individuals and professionals: Includes freelancers, consultants, and business owners

  • Companies and firms: Applicable across organisational structures

  • Income from other sources: Such as capital gains, interest, or rental income

Additional considerations include:

  • Senior citizens with business income: Required to pay advance tax

  • Senior citizens without business income: Not required to pay advance tax

  • Presumptive taxation (Sections 44AD/44ADA): Entire advance tax payable by 15 March

Due Dates for Advance Tax Payment

Advance tax is paid in instalments across the financial year based on specified percentages:

Due Date Percentage of Advance Tax Payable

On or before 15 June

15%

On or before 15 September

45% (less tax paid earlier)

On or before 15 December

75% (less tax paid earlier)

On or before 15 March

100% (less tax paid earlier)

For taxpayers under presumptive taxation schemes, 100% of the advance tax is payable by 15 March. Payments made up to 31 March may still be considered for interest calculation, though the statutory due date remains 15 March.

How to Calculate Advance Tax

Understanding how advance tax is calculated helps in estimating tax liability across the financial year and aligning payments with income earned. The calculation is based on total income, applicable deductions, and taxes already paid.

Steps to Calculate Advance Tax

The process involves a few structured steps:

  1. Estimate total income: Add income from all sources such as salary, business or professional income, capital gains, interest, and rental income.

  2. Apply eligible deductions: Reduce deductions available under Chapter VI-A, such as those under Sections 80C, 80D, and others, to arrive at taxable income.

  3. Calculate tax liability: Compute tax based on the applicable income tax slab rates for the financial year.

  4. Add surcharge and cess: Include applicable surcharge (if income exceeds thresholds) and health and education cess.

  5. Adjust TDS and TCS: Subtract tax already deducted or collected at source during the year.

  6. Determine final liability: If the remaining tax payable exceeds ₹10,000, advance tax becomes applicable.

Example Calculation

Let’s understand this better by calculating the advance tax liability on an amount of ₹50,000: 

Due Date Amount Payable

By 15 June

₹7,500

By 15 September

₹15,000

By 15 December

₹15,000

By 15 March

₹12,500

Advance Tax Late Payment and Interest

Delays or shortfall in advance tax payments may attract interest under applicable provisions:

Section 234B:

  • Applies if less than 90% of total tax is paid by 31 March

  • Interest charged at 1% per month on unpaid amount

Section 234C:

  • Applies for shortfall in instalments

  • Interest charged at 1% per month for specified periods

Consider the following table:

Less than 45% by 15 September

1% per month

3 months
