Advance Tax Calculator FY 2025-26

What is Advance Tax?

Advance Tax refers to paying a part of your annual tax liability before the end of the financial year, in a phased manner. Also known as "pay-as-you-earn" tax, it is mandatory for individuals whose total tax liability in a financial year exceeds ₹10,000.

If you are a freelancer, a business owner, or a salaried individual with substantial non-salary income (like capital gains, rent, or massive interest), you likely need to pay Advance Tax.

Who Needs to Pay Advance Tax?

You are liable to pay Advance Tax if your total tax liability for the year, after deducting TDS (Tax Deducted at Source), is ₹10,000 or more.

Salaried Individuals: Usually, employers deduct TDS on salary, so salaried individuals don't worry about advance tax. However, if a salaried person makes huge capital gains by selling shares or property, or has massive interest income, their tax liability might jump, triggering the need for advance tax.
Freelancers & Professionals: Since clients only deduct a small flat percentage (e.g., 10% under 194J) which rarely covers their full slab rate liability, freelancers almost always have to pay advance tax.
Senior Citizens: Senior citizens (aged 60 or above) who do not have income from a business or profession are exempt from paying advance tax.

Advance Tax Payment Schedule (Due Dates)

For both individuals and corporate taxpayers, advance tax must be paid in four installments throughout the financial year:

On or before June 15: 15% of the total estimated tax liability.
On or before September 15: 45% of the total estimated tax liability (less tax already paid).
On or before December 15: 75% of the total estimated tax liability (less tax already paid).
On or before March 15: 100% of the total estimated tax liability (less tax already paid).

Exception: Taxpayers who have opted for the Presumptive Taxation Scheme under Section 44AD or 44ADA can pay their entire 100% advance tax in a single installment on or before March 15.

Penalties for Non-Payment (Interest under 234B & 234C)

If you fail to pay advance tax, or pay less than required, the Income Tax Department levies heavy interest penalties:

Section 234C (Delay in Installments): If you fail to meet the 15%, 45%, or 75% targets on their respective due dates, a penal interest of 1% per month is charged on the shortfall amount for a period of 3 months.
Section 234B (Shortfall at Year-End): If your total advance tax paid by March 31 is less than 90% of your assessed tax, a penal interest of 1% per month is charged on the shortfall amount from April 1 of the following year until the date you pay the tax.

Formula

Income Tax Calculation Formula

Indian income tax uses progressive tax brackets:

Tax = Sum of (Income in bracket × Tax rate for bracket) - Deductions - Rebates

Tax Slab Calculation Steps

Determine gross income
Subtract deductions (80C, 80D, HRA, etc.)
Calculate taxable income
Apply applicable tax slabs
Add cess (if applicable): 4% on tax amount
Subtract applicable rebates/credits

TDS (Tax Deducted at Source)

TDS is advance tax deducted at the source of income:

TDS Amount = Gross Income × TDS Rate

TDS rates vary by income type:

Salary: 10-30% (depends on income)
Interest: 10% (banks deduct TDS on FD interest)
Dividends: 20%
Freelance income: 10-30%

Frequently Asked Questions

Who is required to pay Advance Tax?

Any individual or entity whose estimated total tax liability for the financial year (after accounting for TDS) is ₹10,000 or more must pay advance tax. This applies to freelancers, businesses, and salaried individuals with significant secondary income (like capital gains, rent, or high interest).

Are senior citizens exempt from Advance Tax?

Yes, resident senior citizens (aged 60 years or above) are exempt from paying advance tax, provided they do not have any income falling under the head "Profits and Gains of Business or Profession".

What happens if I miss an Advance Tax deadline?

If you miss a deadline or pay less than the required percentage, you will be liable to pay penal interest under Section 234B and Section 234C of the Income Tax Act. The interest is typically calculated at 1% per month on the shortfall amount.

How do I calculate Advance Tax if my income fluctuates?

If you have a variable income (like freelancers or business owners), it is best to estimate your income conservatively at the beginning of the year and pay the initial installments. You can adjust the subsequent installments (in December and March) once you have a clearer picture of your exact annual income.

What are the specific due dates for Advance Tax?

For individuals and corporate taxpayers, Advance Tax must be paid in four installments: 15% of total liability by June 15, 45% by September 15, 75% by December 15, and 100% by March 15 of the financial year.

Is Advance Tax applicable on sudden capital gains?

Yes, advance tax applies to capital gains. However, since capital gains cannot be reliably predicted at the start of the year, you only need to calculate and pay advance tax on them in the installments that fall after the capital gains actually arise. No penalty is levied if the tax on capital gains is paid in the remaining installments.

Frequently Asked Questions

Who is required to pay Advance Tax in India?

Any individual whose estimated total tax liability for the financial year exceeds ₹10,000 after accounting for TDS (Tax Deducted at Source) must pay Advance Tax. This includes freelancers, business owners, professionals, and salaried individuals with significant non-salary income such as capital gains, rental income, or interest income.

What are the Advance Tax installment due dates?

Advance Tax is paid in four installments during the financial year: by 15 June, 15 September, 15 December, and 15 March. Each installment requires a cumulative percentage of the estimated annual tax liability to have been paid by that date. Senior citizens (age 60+) with no business income are exempt from Advance Tax.

How does this calculator estimate my Advance Tax liability?

Enter your estimated annual income from all sources — salary, business/profession, capital gains, rent, and other income — along with applicable deductions. The calculator applies the current income tax slab rates to arrive at your estimated tax, deducts TDS already credited, and shows you how much to pay at each installment due date.

What happens if I miss an Advance Tax installment or pay less than required?

If you fail to pay or underpay an installment, interest is charged under Sections 234B and 234C of the Income Tax Act. Section 234C levies interest for deferment of each installment, and Section 234B applies if total advance tax paid is less than a prescribed threshold of the total tax due. Paying on time avoids these additional charges.

Is Advance Tax applicable if my income is only from salary?

Generally, if your entire income comes from salary and your employer deducts TDS correctly, your Advance Tax liability is effectively met through that TDS. However, if you have additional non-salary income that pushes your net tax liability (after TDS) above ₹10,000, you will need to pay the difference as Advance Tax.
