Advance Tax Guide for FY 2025-26: Due Dates & Calculations (With Examples)
Advance tax is one of the most misunderstood yet critical compliances under the Income-tax Act. Many taxpayers still believe that tax is payable only at the time of filing the return, which often results in unnecessary interest and penalties.
This detailed guide explains what advance tax is, who is liable, how it is calculated, due dates, exemptions, interest consequences, and practical examples – in simple, human language.
What is Advance Tax?
Advance tax means paying income tax in installments during the financial year itself, instead of paying the entire tax at the end of the year.
As per the Income-tax Act, if your total tax liability for the year exceeds ₹10,000, you are required to pay tax in advance.
The concept is simple: earn income → estimate tax → pay tax periodically.
Who is Required to Pay Advance Tax?
Advance tax is applicable to almost all categories of taxpayers, including:
- Individuals (salaried, professionals, freelancers)
- Business owners and traders
- Professionals such as doctors, lawyers, consultants, architects
- Partnership firms
- LLPs
- Companies
Salaried Individuals
If sufficient TDS is not deducted by the employer or you have additional income such as rent, capital gains, interest, or side business income, advance tax becomes applicable.
Presumptive Taxpayers
Taxpayers opting for Section 44AD or 44ADA are also liable to pay advance tax, but with a relaxed schedule (explained below).
Who is NOT Required to Pay Advance Tax?
The following taxpayers are exempt:
- Senior citizens (60 years or more)
- No income from business or profession
This exemption is a major relief for retired individuals earning pension or interest income.

How to Calculate Advance Tax (Step-by-Step)
Advance tax is calculated on estimated income, not actual final income.
Step 1: Estimate Annual Income
Include:
- Projected sales or professional receipts
- Other income (interest, rent, capital gains, etc.)
Step 2: Deduct Estimated Expenses
Subtract:
- Business or professional expenses
- Eligible deductions under Chapter VI-A (80C, 80D, etc.)
Step 3: Calculate Tax Liability
Apply applicable tax slab rates and surcharge, if any.
Step 4: Reduce TDS / TCS
Deduct:
- TDS already deducted
- TCS, if applicable
Step 5: Pay Balance as Advance Tax
Split the balance tax liability as per the advance tax schedule.
Practical Example
Mr. Sumt Anand, a consultant, estimates annual income of Rs.12,00,000.
- Tax liability (approx): Rs.1,72,500
- TDS deducted: Rs. 40,000
- Balance tax payable: Rs.1,32,500
Advance tax payable:
- By 15 June – Rs.19,875
- By 15 Sept – Rs. 59,625 (cumulative)
- By 15 Dec – Rs. 99,375 (cumulative)
- By 15 March – Rs. 1,32,500 (cumulative)
Interest for Non-Payment or Short Payment
Failure to pay advance tax correctly attracts interest:
Section 234C
Interest for delay or short payment of installments.
Section 234B
Interest for failure to pay at least 90% of total tax liability by year-end.
These interests are mandatory and cannot be waived in most cases.
Common Mistakes to Avoid
- Ignoring advance tax due to fluctuating income
- Not considering interest, rent, or capital gains
- Assuming TDS covers entire tax liability
- Waiting till March to pay entire tax
