Company Advance Income Tax Calculator
Comprehensive Guide to Calculating Advance Income Tax for Companies
Module A: Introduction & Importance
Advance income tax for companies is a system where corporations pay their estimated tax liability in installments throughout the financial year rather than as a lump sum at year-end. This mechanism, governed by Section 208 of the Income Tax Act, 1961, ensures steady revenue flow for the government while helping companies manage their cash flow more effectively.
For financial year 2024-25 (Assessment Year 2025-26), companies must pay advance tax in four installments with specific due dates: June 15 (15%), September 15 (45%), December 15 (75%), and March 15 (100%). Non-compliance attracts interest under Section 234B (1% per month) and Section 234C (1% for each deferment).

Module F: Expert Tips
Common Mistakes to Avoid
- Underestimating Income: Base calculations on realistic projections, not optimistic scenarios. The Income Tax Department can challenge unreasonably low estimates.
- Ignoring MAT: Even if regular tax is lower, companies must pay Minimum Alternate Tax (15% of book profits).
- Missing Deadlines: Set calendar reminders for June 15, September 15, December 15, and March 15.
- Incorrect Surcharge: Verify income thresholds carefully – the 12% surcharge kicks in at ₹10 crore, not ₹1 crore.
- Not Using Challan 280: Always use the correct challan and select “Advance Tax (100)” as the payment type.
Proactive Strategies
- Quarterly Reviews: Reassess income estimates every quarter and adjust payments accordingly.
- Tax Loss Utilization: Carry forward losses can reduce taxable income if properly documented.
- Section 115JAA Credit: Maintain records to claim MAT credit in future years.
- Digital Payments: Use net banking for instant credit and acknowledgment.
- Professional Audit: Get your advance tax calculations reviewed by a CA for complex scenarios.
Documentation Checklist
- Board resolution authorizing advance tax payments
- Income projection statements with supporting calculations
- Challan counterfoils (Form 280)
- Bank payment acknowledgments
- Previous years’ tax returns for comparison
- Documentation for claimed deductions
Module G: Interactive FAQ
What happens if I pay less than the required advance tax?
Under Section 234B, you’ll pay 1% interest per month on the shortfall from April 1 until the payment date. For example, if your total tax liability is ₹50 lakh but you only paid ₹30 lakh by March 15, you’ll owe:
- ₹20 lakh shortfall × 1% × 12 months = ₹2,40,000 interest
- Additional 1% under Section 234C for each deferred installment
The interest is calculated on the assessed tax (total tax minus TDS/TCS), not just the advance tax.
Can I revise my advance tax estimates during the year?
Yes, you can and should revise estimates when:
- Your actual income exceeds initial projections by >15%
- You receive unexpected windfall profits
- New deductions become available (e.g., R&D approvals)
- There are changes in tax laws mid-year
Use Form 28A to revise estimates with the Assessing Officer if needed. The system allows self-correction in subsequent installments.
How does advance tax differ for foreign companies?
| Parameter | Domestic Company | Foreign Company |
|---|---|---|
| Base Tax Rate | 22-30% | 40% |
| Surcharge Threshold | ₹1 crore/₹10 crore | ₹1 crore |
| Maximum Surcharge | 12% | 5% |
| MAT Applicability | 15% of book profits | Not applicable |
| DTAA Benefits | Limited | Available if eligible |
Foreign companies must also consider transfer pricing regulations and permanent establishment rules when calculating taxable income.
What are the advance tax due dates for FY 2024-25?
| Installment | Due Date | Percentage of Total Tax | Late Payment Interest |
|---|---|---|---|
| First | June 15, 2024 | 15% | 1% per month (Section 234C) |
| Second | September 15, 2024 | 45% (less first installment) | 1% for 3 months |
| Third | December 15, 2024 | 75% (less previous installments) | 1% for 3 months |
| Fourth | March 15, 2025 | 100% (less previous installments) | 1% for 1 month |
Note: If the due date falls on a Sunday/holiday, payment must be made on the previous working day.
How do I calculate advance tax if I have income from multiple sources?
For companies with diverse income streams:
- Segment Income: Categorize into business income, capital gains, house property, and other sources.
- Apply Rates: Use applicable rates for each category (e.g., 22% for business, 20% for long-term capital gains).
- Aggregate: Sum all tax liabilities before applying surcharge and cess.
- Set-off: Adjust for inter-head set-off where permitted (e.g., business losses against business income).
- Foreign Income: Include global income if resident in India, with foreign tax credit under Section 90/91.
Example: A company with ₹5 crore business income and ₹1 crore capital gains would calculate:
- Business tax: ₹5,00,00,000 × 22% = ₹1,10,00,000
- Capital gains tax: ₹1,00,00,000 × 20% = ₹20,00,000
- Total before surcharge: ₹1,30,00,000
