Advance Tax Calculator for Financial Year 2018-19
Comprehensive Guide to Advance Tax for FY 2018-19
Module A: Introduction & Importance
Advance tax is the income tax payable in advance instead of a lump sum payment at year-end. For the financial year 2018-19 (Assessment Year 2019-20), the Income Tax Department mandated advance tax payments for taxpayers whose estimated tax liability exceeds ₹10,000 in a financial year. This system helps the government maintain steady cash flow and reduces the burden of last-minute tax payments for individuals and businesses.
The importance of advance tax includes:
- Avoiding interest penalties under Section 234B and 234C of the Income Tax Act
- Better financial planning by spreading tax payments throughout the year
- Improved cash flow management for both taxpayers and government
- Reduced chances of tax evasion through systematic payment structure

Module D: Real-World Examples
Case Study 1: Salaried Individual (32 years, Old Regime)
Details: Annual salary ₹12,00,000, HRA ₹3,00,000, 80C investments ₹1,50,000, HRA exemption ₹2,40,000
Calculation:
Taxable Income = (12,00,000 + 3,00,000) – (2,40,000 + 1,50,000 + 40,000 standard deduction) = ₹11,70,000
Tax = (2,50,000×0) + (2,50,000×5%) + (5,00,000×20%) + (1,70,000×30%) = ₹1,63,500
Education Cess = 3% of 1,63,500 = ₹4,905
Total Tax = ₹1,68,405
Advance Tax (75% by Dec) = ₹1,26,304
Case Study 2: Senior Citizen (68 years, Old Regime)
Details: Pension income ₹8,00,000, Interest income ₹2,00,000, Medical insurance premium ₹30,000 (80D), Senior citizen savings scheme ₹1,50,000 (80C)
Calculation:
Taxable Income = (8,00,000 + 2,00,000) – (1,50,000 + 30,000 + 50,000 medical expenditure) = ₹8,70,000
Tax = (3,00,000×0) + (5,00,000×20%) + (70,000×30%) = ₹1,26,000
Education Cess = ₹3,780
Total Tax = ₹1,29,780
Advance Tax (45% by Sept) = ₹58,391
Case Study 3: Business Professional (45 years, Old Regime)
Details: Business income ₹25,00,000, Business expenses ₹12,00,000, Depreciation ₹2,00,000, 80C investments ₹1,50,000
Calculation:
Taxable Income = (25,00,000 – 12,00,000 – 2,00,000) – (1,50,000 + 40,000 presumptive) = ₹9,10,000
Tax = (2,50,000×0) + (2,50,000×5%) + (5,00,000×20%) + (1,60,000×30%) = ₹1,49,500
Surcharge (10%) = ₹14,950

Module G: Interactive FAQ
What happens if I don’t pay advance tax by the due dates?
If you fail to pay advance tax by the specified due dates, you’ll be liable to pay interest under:
- Section 234B: 1% per month on the outstanding tax amount if you’ve paid less than 90% of your tax liability by 31st March
- Section 234C:
- 1% per month for 3 months if 15% not paid by 15th June
- 1% per month for 3 months if 45% not paid by 15th September
- 1% per month for 3 months if 75% not paid by 15th December
- 1% per month until payment if 100% not paid by 15th March
For example: If your total tax liability is ₹2,00,000 and you pay:
- ₹0 by 15th June: Interest = ₹2,000 × 3 months = ₹6,000
- ₹50,000 by 15th Sept (should be ₹90,000): Interest = ₹40,000 × 3 months = ₹12,000
- ₹1,20,000 by 15th Dec (should be ₹1,50,000): Interest = ₹30,000 × 3 months = ₹9,000
- ₹1,80,000 by 15th March (should be ₹2,00,000): Interest = ₹20,000 × 1 month = ₹2,000
Total interest = ₹29,000 (14.5% of your tax liability)
How is advance tax different from TDS and self-assessment tax?
| Aspect | Advance Tax | TDS (Tax Deducted at Source) | Self-Assessment Tax |
|---|---|---|---|
| Timing | Paid in installments during the year | Deducted at time of payment | Paid after filing return |
| Who Pays | Taxpayer | Payer (employer, bank, etc.) | Taxpayer |
| When Applicable | If tax liability > ₹10,000 | On specified payments (salary, interest, etc.) | After calculating final tax liability |
| Due Dates | 15 Jun, 15 Sep, 15 Dec, 15 Mar | At time of payment | Before filing return |
| Interest for Non-Payment | Yes (Sec 234B & 234C) | Not applicable to taxpayer | Yes (Sec 234A) |
| Challan Used | ITNS 280 | Not applicable | ITNS 280 |
| Adjustment Against | Final tax liability | Final tax liability | Final tax liability |
Key Relationship: Your final tax liability = (Advance Tax + TDS) – Self-Assessment Tax (if any)
Can I revise my advance tax payments if my income changes?
Yes, you can and should revise your advance tax payments if your income changes significantly during the year. Here’s how:
- Re-estimate Income: Calculate your revised estimated income considering:
- Salary hikes or bonuses
- Capital gains from property or investments
- Additional income from freelance work
- Interest from new fixed deposits
- Rental income from new properties
- Recalculate Tax Liability: Use the same methodology but with updated numbers
- Determine Shortfall: Compare what you’ve already paid with the new calculation
- Pay Additional Tax: Pay the difference in the next installment:
- If revising before 15th June: Adjust first installment
- If revising before 15th Sept: Adjust second installment to cover shortfall from first
- If revising before 15th Dec: Adjust third installment to cover previous shortfalls
- If revising after 15th Dec: Pay entire shortfall by 15th March
- Document Changes: Maintain records of:
- Revised income estimates
- Additional challans paid
- Correspondence with tax consultant (if any)
Important: There’s no formal “revision” process – you simply pay additional tax in subsequent installments. The IT department will consider your total payments when assessing your final liability.

How does advance tax work for freelancers and professionals?
Freelancers and professionals (doctors, lawyers, consultants, etc.) have specific advance tax requirements:
Key Rules:
- Mandatory Payment: Must pay advance tax if liability exceeds ₹10,000, regardless of age
- Estimation Challenge: Income may be irregular, requiring careful estimation
- Presumptive Taxation: Can opt for Section 44AD/44ADA if eligible:
- Section 44AD: 8% of turnover (6% for digital transactions)
- Section 44ADA: 50% of gross receipts for professionals
- Payment Schedule: Same deadlines as others (15 Jun, 15 Sep, etc.)
Calculation Approach:
- Project Income:
- Base on previous year’s earnings
- Adjust for known contracts or projects
- Consider seasonality in your profession
- Track Expenses:
- Maintain records of business expenses
- Differentiate between capital and revenue expenses
- Account for TDS:
- Clients may deduct TDS at 10% (Section 194J)
- This can be adjusted against your advance tax liability
- Use Provisional Numbers:
- First installment can be based on conservative estimates
- Adjust subsequent payments as actual income becomes clearer
Special Considerations:
- Quarterly Variability: If income varies significantly by quarter, you can pay different amounts in each installment (not strictly 15%, 45%, etc.) as long as the total meets requirements
- New Professionals: If first year in business, estimate based on industry averages and adjust as you progress
- Foreign Income: If earning in foreign currency, convert at applicable exchange rates for each receipt
- Retainer Fees: Treat as income when received (not when services are rendered)
Example Calculation:
A freelance graphic designer expects:
- ₹12,00,000 from projects
- ₹2,00,000 expenses (30% of receipts)
- ₹1,50,000 80C investments
- ₹25,000 health insurance (80D)
Calculation:
- Taxable Income = (12,00,000 – 2,00,000) – (1,50,000 + 25,000 + 40,000 standard deduction) = ₹7,85,000
- Tax = (2,50,000×0) + (2,50,000×5%) + (5,00,000×20%) + (85,000×30%) = ₹1,37,500
- Education Cess = ₹4,125
- Total Tax = ₹1,41,625
- Advance Tax Installments:
- 15% by June: ₹21,244
- 45% by Sept: ₹63,731 (total ₹84,975)
- 75% by Dec: ₹1,06,219 (total ₹1,91,194)
- 100% by March: ₹1,41,625
