Advance Income Tax Deposit Calculator
Comprehensive Guide to Advance Income Tax Deposits
Module A: Introduction & Importance
Advance income tax is a system where taxpayers pay their estimated tax liability in installments during the financial year rather than as a lump sum at year-end. This mechanism was introduced under Section 208 of the Income Tax Act, 1961 to ensure regular cash flow to the government and reduce the burden of year-end tax payments on taxpayers.
The Income Tax Department mandates advance tax payments when your estimated tax liability for the year exceeds ₹10,000. Failure to comply attracts interest penalties under Section 234B (for non-payment) and Section 234C (for short payment or deferment).
Key benefits of advance tax payments:
- Avoids last-minute financial strain during tax filing season
- Prevents interest penalties that can accumulate to significant amounts
- Improves cash flow management for both taxpayers and government
- Demonstrates financial discipline and tax compliance

- Rebate Selection: Indicate if you qualify for ₹12,500 rebate under Section 87A (income ≤ ₹5,00,000 for new regime; ≤ ₹3,50,000 for old regime).
- Choose Installment: Select which quarterly installment you’re calculating (1st to 4th).
- Review Results: The calculator displays:
- Estimated annual tax liability
- Advance tax due for selected installment
- Relevant due date
- Potential penalties for non-compliance
Pro Tip: For most accurate results, update your income estimates quarterly as your actual earnings may vary from initial projections.
Module C: Formula & Methodology
The calculator uses the following methodology to compute advance tax:
Step 1: Calculate Annual Tax Liability
For both regimes, we first determine taxable income:
Taxable Income = (Annual Income) - (Deductions) - (Standard Deduction if applicable)
Then apply the appropriate tax slabs:
| Income Range (₹) | New Regime Rate | Old Regime Rate |
|---|---|---|
| 0 – 3,00,000 | 0% | 0% |
| 3,00,001 – 6,00,000 | 5% | 5% |
| 6,00,001 – 9,00,000 | 10% | 20% |
| 9,00,001 – 12,00,000 | 15% | 20% |
| 12,00,001 – 15,00,000 | 20% | 30% |
| Above 15,00,000 | 30% | 30% |
Add 4% health and education cess on the computed tax.
Step 2: Apply Section 87A Rebate
If eligible, subtract rebate (maximum ₹12,500 for new regime; ₹2,500 for old regime if income ≤ ₹3,50,000).
Step 3: Determine Advance Tax Installments
Section 211 specifies the following schedule:
- 1st Installment: 15% of estimated tax by June 15
- 2nd Installment: 45% (less any previous payments) by September 15
- 3rd Installment: 75% (less any previous payments) by December 15
- 4th Installment: 100% (less any previous payments) by March 15
Step 4: Calculate Penalties
For non-payment or short payment:
- Section 234B: 1% per month simple interest on unpaid amount
- Section 234C:
- 1% per month for 1st/2nd installment shortfall (3 months each)
- 1% for 3rd installment shortfall (1 month)

Module G: Interactive FAQ
Who is required to pay advance tax?
Advance tax is mandatory if your estimated tax liability for the year exceeds ₹10,000 after accounting for TDS. This applies to:
- Salaried individuals with income from other sources (rental, capital gains, etc.)
- Freelancers and professionals
- Business owners
- Senior citizens with business income (others are exempt)
Exception: Senior citizens (age ≥ 60) without business income are exempt from advance tax under Section 207.
What happens if I don’t pay advance tax?
The Income Tax Department imposes two types of penalties:
- Section 234B: 1% simple interest per month on the unpaid tax amount from April 1 until the date of payment.
- Section 234C: Specific penalties for deferred payments:
- 1% per month for 3 months if 1st installment (15%) is shortpaid
- 1% per month for 3 months if 2nd installment (45%) is shortpaid
- 1% for 1 month if 3rd installment (75%) is shortpaid
Example: If your tax liability is ₹2,00,000 and you pay nothing until March, you’ll owe:
- ₹2,000 under Section 234B (1% × 12 months × ₹2,00,000)
- ₹6,000 under Section 234C (1% × 3 months × ₹2,00,000 for each missed installment)
- Total penalty: ₹8,000 (4% of tax due)
How do I pay advance tax online?
Follow these steps to pay advance tax online:
- Visit the TIN NSDL portal or income tax e-filing portal
- Select Challan 280
- Enter PAN, assessment year (e.g., 2025-26 for FY 2024-25)
- Select “Advance Tax (100)” as payment type
- Enter your bank details and complete payment
- Download the challan receipt (contains CIN and payment details)
- Verify the payment in Form 26AS after 3-5 days
Important: Always select the correct assessment year (the year after the financial year). For FY 2024-25, the assessment year is 2025-26.
Can I revise my advance tax payments if my income changes?
Yes, you can and should revise your advance tax payments if:
- Your actual income exceeds initial estimates
- You receive unexpected income (bonus, capital gains, etc.)
- Your deductions change (additional 80C investments, etc.)
How to revise:
- Recalculate your estimated annual tax
- Determine the shortfall in previous installments
- Pay the additional amount in the next installment
- Ensure cumulative payments meet the required percentages by each due date
Example: If your income increases in October, adjust your December and March payments to cover the additional liability.
What is the difference between advance tax and self-assessment tax?
| Aspect | Advance Tax | Self-Assessment Tax |
|---|---|---|
| Timing | Paid in installments during the financial year | Paid before filing ITR (after year-end) |
| Purpose | Pre-payment of estimated tax liability | Final settlement of tax after actual income is known |
| Due Dates | June 15, Sept 15, Dec 15, March 15 | Before filing ITR (usually July 31) |
| Penalty | Interest under Sections 234B/C | No penalty if paid before ITR filing |
| Calculation Basis | Estimated income | Actual income as per ITR |
| Challan Type | Challan 280 (select “Advance Tax”) | Challan 280 (select “Self-Assessment Tax”) |
Key Insight: Advance tax is about paying as you earn, while self-assessment tax is about settling any remaining balance when you file your return.
How does advance tax work for capital gains?
Capital gains present unique challenges for advance tax because:
- Timing is unpredictable (you may sell assets anytime during the year)
- Amounts can be substantial, significantly increasing your tax liability
Rules for capital gains:
- If you realize capital gains before December 15, you must include them in your advance tax calculations for that year.
- If gains occur after December 15, you can pay the entire tax by March 15 (no penalty if previous installments were correct based on information available then).
- For gains from equity shares/equity-oriented funds (STCG at 15% or LTCG at 10%), calculate tax separately.
- For property sales, consider the entire sale amount (even if you’ll reinvest under Sections 54/54F).
Example: If you sell a property in November 2024 for ₹80,00,000 (purchased for ₹40,00,000 in 2018):
- Long-term capital gain: ₹40,00,000
- Tax at 20% with indexation: ≈ ₹6,80,000
- Must include this in your December 15 installment (75% of total liability)
What documents should I keep for advance tax payments?
Maintain these records for at least 6 years (until the assessment is complete):
- Challan Receipts: The CIN (Challan Identification Number) is critical for matching payments
- Bank Statements: Showing the tax payment transactions
- Form 26AS: Annual tax credit statement (verify all payments appear)
- Income Estimates: Your calculations/workings for estimated income
- Investment Proofs: For deductions claimed (80C, 80D, etc.)
- Capital Gains Calculations: If applicable, with purchase/sale deeds
- Previous Years’ ITRs: For reference and consistency checks
Pro Tip: Create a dedicated folder (physical or digital) for all tax-related documents. Use a spreadsheet to track:
- Payment dates
- Amounts paid
- Challan numbers
- Bank reference numbers
