Formula & Methodology Behind the Calculator
The advance tax calculation for AY 2018-19 follows a specific methodology prescribed by the Income Tax Department. Here’s the detailed breakdown:
1. Taxable Income Calculation
Taxable Income = (Total Income) – (Deductions)
Where:
- Total Income: Sum of all income heads (business, capital gains, other sources)
- Deductions: Eligible deductions under Chapter VI-A (Sections 80C to 80U)
2. Tax Liability Calculation
The calculator uses different formulas based on the selected regime:
Normal Tax Regime:
Tax Liability = (Taxable Income × 30%) + Surcharge + Cess
MAT Regime:
Tax Liability = (Book Profit × 18.5%) + Surcharge + Cess
Where Book Profit is calculated as per Section 115JB
3. Surcharge Calculation
| Income Range | Surcharge Rate | Effective Tax Rate (including surcharge) |
|---|---|---|
| Up to ₹1 crore | 0% | 30.00% |
| ₹1 crore to ₹10 crore | 7% | 32.10% |
| Above ₹10 crore | 12% | 33.60% |
4. Health & Education Cess
Cess = (Tax Liability + Surcharge) × 4%
5. Total Tax Payable
Total Tax = Tax Liability + Surcharge + Cess
6. Advance Tax Calculation
Advance Tax Due = Total Tax – Advance Tax Already Paid
7. Installment Schedule (Section 211)
| Installment | Due Date | Percentage of Total Tax |
|---|---|---|
| 1st Installment | 15th June | 15% |
| 2nd Installment | 15th September | 45% |
| 3rd Installment | 15th December | 75% |
| 4th Installment | 15th March | 100% |
Important Note: For companies opting for MAT, the advance tax is calculated at 18.5% of book profits (plus surcharge and cess) as per Section 115JAA.

Interactive FAQ: Advance Tax for Companies (AY 2018-19)
What is the due date for the first installment of advance tax for AY 2018-19?
The due date for the first installment of advance tax for AY 2018-19 (FY 2017-18) was 15th June 2017. Companies were required to pay at least 15% of their estimated total tax liability by this date.
The complete schedule was:
- 15th June 2017: 15% of total tax
- 15th September 2017: 45% of total tax (cumulative)
- 15th December 2017: 75% of total tax (cumulative)
- 15th March 2018: 100% of total tax
Missing these deadlines attracts interest under Sections 234B and 234C of the Income Tax Act.
How is MAT (Minimum Alternate Tax) calculated for advance tax purposes?
For AY 2018-19, MAT was calculated as follows:
- Determine Book Profit: Calculate as per Section 115JB (starts with net profit as per P&L account, with specific additions and deductions)
- Apply MAT Rate: 18.5% of book profit
- Add Surcharge:
- 0% if book profit ≤ ₹1 crore
- 7% if ₹1 crore < book profit ≤ ₹10 crore
- 12% if book profit > ₹10 crore
- Add Cess: 4% of (MAT + Surcharge)
Important: The advance tax is calculated on the MAT liability, not the normal tax liability, if MAT is higher. Companies must compare both and pay the higher amount.
Example: If your book profit is ₹5 crore:
- MAT = ₹5,00,00,000 × 18.5% = ₹92,50,000
- Surcharge = ₹92,50,000 × 7% = ₹6,47,500
- Cess = (₹92,50,000 + ₹6,47,500) × 4% = ₹3,95,800
- Total MAT Liability = ₹1,02,93,300
What happens if I underpay my advance tax for AY 2018-19?
Underpayment of advance tax attracts interest penalties under two sections:
1. Section 234B: Interest for Default in Payment of Advance Tax
- Applies if advance tax paid is less than 90% of assessed tax
- Interest rate: 1% per month (simple interest)
- Calculation period: From 1st April to date of actual payment
2. Section 234C: Interest for Deferment of Advance Tax
- Applies for shortfall in individual installments
- Interest rates:
- 1% per month for first three installments
- 1% for March installment shortfall
- Calculation period: From due date to actual payment date
Example Calculation:
If your total tax liability is ₹50,00,000 but you only paid ₹30,00,000 by 15th March:
- Section 234B interest: (₹50,00,000 – ₹30,00,000) × 1% × 12 months = ₹2,40,000
- Section 234C interest would depend on which installments were shortpaid
Important: These interest payments are mandatory and cannot be waived. They are calculated automatically by the income tax department when you file your return.
Can I revise my advance tax estimates during the year?
Yes, you can and should revise your advance tax estimates if:
- Your actual income turns out to be higher than initially estimated
- You receive unexpected income (capital gains, bonuses, etc.)
- Your deductions are less than initially projected
- There are changes in tax laws affecting your liability
How to Revise:
- Recalculate your estimated total income
- Use our calculator to determine the revised tax liability
- Pay the additional amount in the next installment
- Ensure cumulative payments meet the required percentages by each due date
Important Considerations:
- Revisions should be made as soon as you become aware of changes
- You cannot claim refunds for overpaid advance tax until filing your return
- Document the reasons for revision for your records
- Consult your tax advisor for significant revisions (>20% change)
Example: If you initially estimated ₹1 crore income but actually earn ₹1.2 crore, you should:
- Recalculate tax on ₹1.2 crore
- Pay the additional tax in the next installment
- Ensure you meet the cumulative payment requirements
Are there any exemptions from advance tax for companies?
While most companies are required to pay advance tax, there are specific exemptions and special cases:
1. Full Exemptions:
- Companies whose tax liability is less than ₹10,000 for the year
- Non-resident companies with no permanent establishment in India (subject to DTAA provisions)
2. Partial Relief:
- New Companies: First year of operation has relaxed rules (can pay entire tax by March installment)

How does GST impact advance tax calculations for AY 2018-19?
GST implementation on 1st July 2017 had several impacts on advance tax calculations for AY 2018-19:
1. Input Tax Credit (ITC) Considerations:
- GST ITC cannot be claimed as a deduction for income tax purposes
- However, it reduces your cost of goods/services, indirectly affecting taxable income
- Our calculator automatically accounts for this by using your net income figures
2. Revenue Recognition:
- GST is not part of your income (it’s a pass-through tax)
- Ensure your income figures exclude GST collected from customers
- Similarly, exclude GST paid on expenses from your deductions
3. Transition Provisions:
- For FY 2017-18, companies had to account for:
- Pre-GST period (April-June 2017) under old tax regime
- Post-GST period (July 2017-March 2018) under new regime
- Transition credits from old laws could affect your cash flow
4. Cash Flow Management:
- GST payments (monthly/quarterly) may affect your liquidity for advance tax
- Plan your advance tax payments considering GST outflows
- Use our calculator’s results to align with your GST payment schedule
5. Specific Industries:
- Exporters: GST refunds may improve cash flow for tax payments
- Manufacturers: ITC accumulation may reduce effective costs
- Service Providers: Working capital changes due to GST timing differences
Pro Tip: Maintain separate accounts for GST and income tax liabilities to avoid confusion. Our calculator helps you focus solely on the income tax component by using your net income figures after all adjustments.
