Module A: Introduction & Importance of Advance Tax for Individuals
Advance tax refers to the income tax that should be paid in advance instead of lump-sum payment at year-end. Under Section 208 of the Income Tax Act, 1961, every taxpayer whose estimated tax liability for the year exceeds ₹10,000 must pay advance tax in quarterly installments. This system helps the government maintain steady cash flow and reduces the burden of year-end tax payments for individuals.
The due dates for advance tax payments are strictly enforced:
- 15th June – 15% of advance tax
- 15th September – 45% of advance tax (less any paid in June)
- 15th December – 75% of advance tax (less any paid earlier)
- 15th March – 100% of advance tax
Non-payment or underpayment of advance tax attracts interest under Section 234B (1% per month) and Section 234C (1% for each deferment period). Senior citizens (age 60+ without business income) are exempt from advance tax requirements.
According to Income Tax Department data, over 6.7 crore individuals filed ITRs in AY 2023-24, with advance tax collections growing by 18% YoY. Proper advance tax planning can save you from last-minute financial stress and potential penalties.

Module C: Formula & Methodology Behind the Calculator
Our calculator uses the official income tax computation mechanism prescribed by the CBDT. Here’s the exact methodology:
Step 1: Calculate Taxable Income
Formula: Taxable Income = (Gross Income) – (Deductions under Chapter VI-A) – (Standard Deduction if applicable)
Step 2: Apply Tax Slabs
New Tax Regime (Default)
| Income Range (₹) | Tax Rate | Surcharge | Health & Education Cess |
|---|---|---|---|
| Up to 3,00,000 | 0% | – | – |
| 3,00,001 – 6,00,000 | 5% | – | 4% |
| 6,00,001 – 9,00,000 | 10% | – | 4% |
| 9,00,001 – 12,00,000 | 15% | – | 4% |
| 12,00,001 – 15,00,000 | 20% | – | 4% |
| Above 15,00,000 | 30% | 10-37% | 4% |
Step 3: Calculate Advance Tax Installments
The quarterly breakup follows Section 211 rules:
- Q1 (15%): 15% of estimated tax by 15th June
- Q2 (45%): 45% (less Q1 payment) by 15th September
- Q3 (75%): 75% (less Q1+Q2) by 15th December
- Q4 (100%): Balance by 15th March
Step 4: Adjust for TDS and Final Output
Net Advance Tax = (Total Tax Liability) – (TDS Paid) – (Rebate u/s 87A)
Module D: Real-World Examples with Specific Numbers
Case Study 1: Salaried Professional (New Regime)
Details: Ramesh, 35, estimates ₹12,50,000 annual income with ₹1,50,000 deductions (80C + 80D). TDS deducted: ₹75,000. Current quarter: Q2.
Calculation:
- Taxable Income: ₹12,50,000 – ₹1,50,000 = ₹11,00,000
- Tax Liability: ₹11,00,000 × applicable slabs = ₹1,37,500
- Less TDS: ₹1,37,500 – ₹75,000 = ₹62,500
- Q2 Payment (45%): ₹61,875 – ₹20,625 (Q1) = ₹41,250 due by 15th Sept
Case Study 2: Freelancer (Old Regime)
Details: Priya, 42, expects ₹18,00,000 income with ₹3,00,000 deductions. No TDS. Current quarter: Q3.
Key Findings:
- Old regime benefits from higher deductions (₹3,00,000 vs ₹1,50,000 in new regime)
- Q3 payment: ₹2,02,500 (75% of ₹2,70,000 total tax)
- Interest saved: ₹4,500 by paying on time vs December deadline
Case Study 3: Senior Citizen (Exempt Scenario)

Module G: Interactive FAQ Section
What happens if I don’t pay advance tax on time?
Under Section 234B, you’ll pay 1% simple interest per month on the outstanding amount. For example, if you owe ₹1,00,000 and pay 3 months late, you’ll pay ₹3,000 in interest (1% × ₹1,00,000 × 3). Section 234C adds another 1% for each deferred installment. The calculator shows exact interest implications in the results.
Can I switch between old and new tax regimes during the year?
No, you must choose one regime at the start of the financial year and stick with it. However, you can compare both regimes using our calculator before making your final choice. Business owners have until the ITR filing deadline to choose, but salaried individuals must inform their employer at the beginning of the year.

The calculator automatically applies:
- 10% surcharge for income between ₹50 lakh to ₹1 crore

- Long-term capital gains (LTCG) above ₹1 lakh are taxed at 10%
- You must pay advance tax even if you haven’t received the sale proceeds yet
How does the calculator handle income from multiple sources?

What’s the difference between advance tax and self-assessment tax?

- Due dates: 15th June, Sept, Dec, March
- Paid after year-end but before filing ITR
