Advance Tax Calculator 2024
Module A: Introduction to Advance Tax Calculation
Advance tax refers to the income tax that should be paid in advance instead of lump-sum payment at year-end. This system was introduced to ensure regular cash flow to the government and reduce the burden of last-minute tax payments for taxpayers. Under Section 208 of the Income Tax Act, 1961, every taxpayer whose estimated tax liability for the year exceeds ₹10,000 is required to pay advance tax.
The concept of advance tax is particularly crucial for:
- Self-employed professionals and business owners
- Freelancers and consultants with variable income
- Salaried individuals with significant additional income sources
- Senior citizens with pension and investment income
Failure to pay advance tax or underpayment attracts interest under Section 234B (1% per month) and Section 234C (1% for each deferment period). Our calculator helps you determine the exact amounts and due dates to avoid these penalties.

Module G: Interactive FAQ
Who is required to pay advance tax?
Any taxpayer (individual, HUF, company, etc.) whose estimated tax liability for the financial year exceeds ₹10,000 is required to pay advance tax. This applies to:
- Salaried individuals with income from other sources
- Freelancers and professionals
- Business owners
- Senior citizens with business income (pensioners are exempt if no business income)
Exemptions: Senior citizens (60+ years) without business income are not required to pay advance tax.
What happens if I don’t pay advance tax or pay less than required?
The Income Tax Department levies interest penalties for non-payment or underpayment of advance tax:
- Section 234B: 1% per month simple interest on the shortfall from the assessed tax
- Section 234C: 1% simple interest for each month of deferment (3 months for each installment)
Example: If your total tax liability is ₹1,00,000 and you pay nothing by 15th June, you’ll owe:
- ₹1,000 (1% of ₹1,00,000) for June deferment
- Additional interest for subsequent deferments
These interests are calculated separately and added to your final tax demand.
How do I pay advance tax online?
Follow these steps to pay advance tax online:
- Visit NSDL e-payment portal
- Select “CHALLAN NO./ITNS 280”
- Enter PAN, assessment year, and address details
- Select “Advance Tax (100)” as payment type
- Choose your bank and make payment
- Download/save the challan counterfoil (Form 280)

Can I revise my advance tax payments if my income changes?
Yes, you can and should revise your advance tax payments if your income estimates change significantly. Here’s how:
- If income increases: Pay the additional tax in the next installment
- If income decreases: You can pay less in subsequent installments
- No formal revision process – just adjust future payments
- Final reconciliation happens when filing ITR
Example: If you paid ₹30,000 by June but later realize your income will be lower, you can pay only ₹15,000 (instead of ₹45,000) by September.
How is advance tax different from self-assessment tax?
The key differences are:
| Aspect | Advance Tax | Self-Assessment Tax |
|---|---|---|
| Timing | Paid in installments during the year | Paid before filing ITR |
| Purpose | Pre-payment of estimated tax liability | Balance tax after TDS/advance tax |
| Due Dates | 15 Jun, 15 Sep, 15 Dec, 15 Mar | Before ITR filing deadline |
| Applicability | If tax liability > ₹10,000 | If tax remains after credits |
| Interest | 1% per month for shortfall | 1% per month for late payment |
Example: If your total tax is ₹50,000 and you paid ₹40,000 as advance tax, you’ll pay ₹10,000 as self-assessment tax before filing ITR.
What documents should I keep as proof of advance tax payment?
Maintain these documents for at least 6 years (assessment period):
- Challan Counterfoil (Form 280): The receipt generated after payment
- Bank Statement: Showing the tax payment transaction
- BSR Code Receipt: If paid through bank branch
- Form 26AS: Annual tax statement showing credits (available on Income Tax Portal)
