Advance tax is often misunderstood as an “extra” compliance burden. It is simply the Government’s mechanism to spread Tax liability across the financial year to ensure smooth financial management. Timely payment of advance tax prevents levy of interest for nonpayment & for deferment of advance tax instalments. It also helps to reduce year end pressure and avoids a large lump sum out flow.
What is Advance Tax?
Under Section 208 of the Income-tax Act, 1961, every assessee (individual, firm, company, LLP, etc.) is required to pay advance tax if their total tax liability for the financial year is Rs. 10,000 or more. Timely payment of advance tax gives peace of mind and helps to avoid last minute rush during ITR filing.
Salaried individuals generally assume that since TDS is deducted on salary, they don’t need to worry about advance tax. However, those with additional income (capital gains, interest, freelance work, etc.) must independently evaluate their advance tax liability or inform employer about additional income so that higher / adequate TDS can be deducted from Salary.
Advance Tax Applies to:
- Business income
- Professional income
- Capital gains
- Rental income
- Interest income
- Dividend income
- Any other taxable income
Due Dates for Advance Tax
As per Section 211, advance tax is payable in four instalments:
The following table illustrates the deadlines for advance tax payments during the financial year:
| Due Date | Normal Taxpayers | Taxpayers Under Presumptive Tax Scheme (44AD/44ADA) |
| 15th June | Up to 15% of the advance tax payable | NIL |
| 15th September | Up to 45% of the advance tax payable | NIL |
| 15th December | Up to 75% of the advance tax payable | NIL |
| 15th March | Up to 100% of the advance tax payable | Up to 100% of the advance tax payable |
For taxpayers opting for the presumptive taxation scheme under Section 44AD or 44ADA, the entire advance tax is payable in one instalment on or before 15th March.
Any tax paid up to 31st March is treated as advance tax.
When Does Default Occur?
Advance tax default typically arises in two situations:
- Non-payment or short payment of instalments
- Failure to pay at least 90% of total tax liability before 31st March
These defaults trigger interest under Sections 234B and 234C.
Interest Under Section 234C – Deferment of Instalments
Section 234C applies when instalments are not paid as per the prescribed due dates or is paid less than the required percentage
Interest Rate:
- 1% per month for 3 months (For June, September & December shortfall)
- 1% charged for 1 month for March month instalment/shortfall
It is calculated on the shortfall in each instalment.
However, there is relief where shortfall arises due to underestimation of:
- Capital gains
- Dividend income
- Income from lotteries
- Casual Income, etc.
If tax on such income is paid in subsequent instalments, 234C interest may not apply.
Interest Under Section 234B – Default in Payment of Advance Tax
Section 234B applies if the total tax liability exceeds Rs.10,000 and
- Advance tax paid is less than 90% of assessed tax, or
- No advance tax is paid despite liability.
Interest Rate:
- 1% per month or part of month
It is calculated from 1st April of the assessment year until the date of payment of tax or date of completion of assessment.
Practical Example
Suppose total tax liability for FY 2025–26 is ₹10,00,000.
- If only ₹6,00,000 is paid as advance tax,
- Balance ₹4,00,000 is paid while filing return in July,
Then:
- 234C applies for instalment shortfalls.
- 234B applies from 1st April till July on ₹4,00,000.
This significantly increases the final tax outflow.
Key Planning Strategies to Avoid Interest
Advance tax management is not about overpaying – it is about systematic planning, estimation & timely payment of advance tax during the financial year.
- Quarterly income review – Especially for businesses and professionals.
- Tracking capital gains immediately – Property and share transactions often create sudden tax liability.
- Monitoring dividend and interest income – Particularly where TDS is low or absent.
- Use tax computation projections before each due date.
- Recalculate after December – The December instalment is crucial since it covers 75% liability.
Advance tax should be treated as a financial discipline, not a compliance afterthought.
Special Points to Remember
- Senior citizens (60 years or more) without business or professional income are not liable to pay advance tax.
- MAT (Section 115JB) and AMT (Section 115JC) are also subject to advance tax provisions.
- Interest under Sections 234B and 234C is mandatory and cannot be waived except under specific CBDT relief notifications.
- Even taxpayers opting for the new tax regime under Section 115BAC must comply with advance tax provisions.
- Advance tax paid till 31st March is treated as advance tax for that financial year
