As the final instalment deadline for advance tax approaches on 15 March, millions of taxpayers across India—especially individuals with income sources beyond salary—are preparing to meet their tax obligations under the “Pay as You Earn” system mandated by the Income Tax Department.
Failure to pay advance tax on time can silently build up financial liabilities in the form of interest and penalties, which eventually surface at the end of the financial year. This article explains what advance tax is, who needs to pay it, how deadlines work, and what happens if you miss the due date.

What Is Advance Tax?
Advance tax is a mechanism under which taxpayers must estimate their total income for the financial year and pay tax in instalments before the year ends, instead of waiting for the regular return-filing season. This ensures that taxes are paid as the income is earned, reducing last-minute burden for both taxpayers and the government.
Why Does Advance Tax Exist?
The system, governed by Sections 207 to 219 of the Income Tax Act, 1961, allows the government to maintain a steady inflow of revenue throughout the year. It applies to income from:
-
Business or profession
-
Freelancing
-
Capital gains
-
Rental income
-
Other non-salary sources
Even salaried individuals must pay advance tax if TDS does not cover their total tax liability.
Advance Tax Instalments and Due Dates
Taxpayers must pay advance tax in four instalments. Here is a clear breakdown:
Advance Tax Instalment Schedule
| Due Date | Percentage of Total Tax Payable | Explanation |
|---|---|---|
| 15 June | 15% | Pay first instalment of estimated tax |
| 15 September | 45% (minus tax already paid) | Second instalment |
| 15 December | 75% (minus tax already paid) | Third instalment |
| 15 March | 100% (minus tax already paid) | Final instalment |
| Up to 31 March | Treated as Advance Tax | Last chance to pay without being considered self-assessment |
Missing any of these deadlines triggers interest under Sections 234B and 234C.

Exemption for Senior Citizens
The Income Tax Department clarifies:
A resident senior citizen aged 60+ years, who does not have income from a business or profession, is exempt from paying advance tax.
What Happens If You Miss the Advance Tax Deadline?
Missing the deadline or paying less than required triggers statutory interest. These charges apply automatically.
Interest Under Section 234B – Default in Payment
-
Levied when at least 90% of total tax is not paid as advance tax.
-
Interest rate: 1% per month or part of the month.
-
Applies from 1 April of the assessment year until the remaining tax is paid.
Interest Under Section 234C – Delay in Instalments
-
Applied when instalments are not paid by the due dates.
-
Interest rate: 1% per month on the shortfall.
Penalty Impact Table
| Scenario | Applicable Section | Penalty Type | Rate |
|---|---|---|---|
| Advance tax not paid at all | 234B | Default penalty | 1% per month |
| Instalments paid late | 234C | Deferment penalty | 1% per month |
| Last-minute payments after 31 March | 234B + 234C | Combined interest | 1% each |
These interest liabilities accumulate silently and often hit taxpayers unexpectedly at return filing.
