What is Advance Tax?

Advance Tax is the income tax paid during the financial year instead of paying the entire tax after the year ends.

It is also known as "Pay As You Earn Tax."

Instead of paying one large amount at the time of ITR filing, taxpayers pay tax in installments throughout the year.

Who Should Pay Advance Tax?

You must pay Advance Tax if:

  • Your total tax liability after deducting TDS is ₹10,000 or more.

  • You are a freelancer.

  • You are a consultant.

  • You run a business.

  • You are a self-employed professional.

  • You earn commission income.

  • You receive rental income.

  • You earn capital gains (where applicable).

  • You earn income from multiple sources.

Who is Exempt from Advance Tax?

Generally, the following taxpayers are not required to pay Advance Tax:

  • Resident Senior Citizens (aged 60 years or above) who do not have business or professional income.

  • Taxpayers whose tax liability after TDS is less than ₹10,000.




Advance Tax Due Dates 2026

For most taxpayers, Advance Tax must be paid in four installments.

Due DateMinimum Advance Tax Payable
15 June15% of total tax liability
15 September45% of total tax liability
15 December75% of total tax liability
15 March100% of total tax liability

Timely payment helps avoid interest under Sections 234B and 234C.




How to Calculate Advance Tax?

Follow these simple steps.

Step 1: Estimate Your Annual Income

Calculate income from all sources:

  • Salary

  • Business income

  • Professional income

  • Freelancing

  • Rent

  • Interest

  • Capital gains

  • Other income

Step 2: Calculate Gross Total Income

Add all your estimated income together.

Example:

Salary = ₹8,00,000

Freelancing = ₹4,00,000

Interest Income = ₹50,000

Gross Total Income = ₹12,50,000

Step 3: Claim Eligible Deductions

Reduce deductions such as:

  • Section 80C

  • Section 80D

  • Section 80G

  • Other eligible deductions

Suppose total deductions are ₹1,50,000.

Taxable Income becomes:

₹12,50,000 − ₹1,50,000 = ₹11,00,000

Step 4: Calculate Income Tax

Calculate tax according to your chosen tax regime (Old or New).

Suppose your total tax liability comes to:

₹1,15,000

Step 5: Deduct TDS

Suppose your employer has already deducted:

TDS = ₹35,000

Remaining Tax Liability:

₹1,15,000 − ₹35,000 = ₹80,000

Since it exceeds ₹10,000, Advance Tax is applicable.




Advance Tax Calculation Example

Let's understand with a practical example.

Example

Rahul is a freelance graphic designer.

Estimated Professional Income = ₹18,00,000

Tax Liability = ₹2,40,000

TDS Deducted = ₹40,000

Remaining Tax = ₹2,00,000

Advance Tax Installments:

Due DateAmount
15 June₹30,000
15 September₹90,000 (Cumulative)
15 December₹1,50,000 (Cumulative)
15 March₹2,00,000 (Total)

This ensures Rahul avoids interest on delayed payment.
