India Income Tax Calculator AY 2020-21
Introduction & Importance of Income Tax Calculation AY 2020-21
Income tax calculation for Assessment Year (AY) 2020-21 in India represents one of the most critical financial exercises for taxpayers. This period covers income earned between April 1, 2019, and March 31, 2020, with tax filings due by July 31, 2020 (extended to November 30, 2020, due to COVID-19).
The Income Tax Act, 1961, governs these calculations, with AY 2020-21 introducing several important changes:
- Optional new tax regime with lower rates but fewer exemptions
- Increased standard deduction from ₹40,000 to ₹50,000
- Enhanced surcharge rates for high-income individuals
- New provisions for startups and affordable housing
Accurate calculation ensures compliance with Income Tax Department regulations while optimizing your tax liability. The Union Budget 2020 introduced significant structural changes that made this year’s calculations particularly complex, requiring careful consideration of which regime offers better savings.

Formula & Methodology Behind the Calculator
Our calculator implements the exact computation logic specified in the Income Tax Act, 1961, as amended by Finance Act, 2020. Here’s the detailed methodology:
1. Taxable Income Calculation
Taxable Income = (Gross Total Income) – (Deductions under Chapter VI-A) – (Standard Deduction)
Where Chapter VI-A deductions include:
| Section | Deduction Type | Maximum Limit (₹) |
|---|---|---|
| 80C | Investments (PPF, ELSS, etc.) | 1,50,000 |
| 80D | Medical Insurance | 25,000 (self) + 25,000 (parents) |
| 80G | Donations | No limit (subject to conditions) |
| 80TTA | Savings Account Interest | 10,000 |
2. Tax Calculation (Old Regime)
| Income Range (₹) | Below 60 | 60-80 | Above 80 |
|---|---|---|---|
| Up to 2,50,000 | 0% | 0% | 0% |
| 2,50,001 – 5,00,000 | 5% | 5% | 0% |
| 5,00,001 – 10,00,000 | 20% | 20% | 20% |
| Above 10,00,000 | 30% | 30% | 30% |
3. Tax Calculation (New Regime – Optional)
| Income Range (₹) | Tax Rate |
|---|---|
| Up to 2,50,000 | 0% |
| 2,50,001 – 5,00,000 | 5% |
| 5,00,001 – 7,50,000 | 10% |
| 7,50,001 – 10,00,000 | 15% |
| 10,00,001 – 12,50,000 | 20% |
| 12,50,001 – 15,00,000 | 25% |
| Above 15,00,000 | 30% |
4. Surcharge Calculation
Applied on income tax (before cess):
- 10% if total income > ₹50 lakh
- 15% if total income > ₹1 crore
- 25% if total income > ₹2 crore (37% for > ₹5 crore)
5. Health & Education Cess
4% of (Income Tax + Surcharge)

Can I switch between old and new tax regimes every year?
For salaried individuals, the choice must be communicated to the employer at the start of the financial year (FY 2019-20 in this case) and remains fixed for that year.
For business professionals, the option can be exercised each year when filing ITR, but once chosen for a business, it becomes permanent for that business.
The new regime becomes mandatory if you have business income and opt for it in any year.
How is surcharge calculated for high-income individuals?
The surcharge structure for AY 2020-21 is progressive:
| Total Income | Surcharge Rate |
|---|---|
| ₹50 lakh – ₹1 crore | 10% |
| ₹1 crore – ₹2 crore | 15% |
| ₹2 crore – ₹5 crore | 25% |
| Above ₹5 crore | 37% |
Note: Surcharge is calculated on the income tax amount (before adding cess), not on the total income.
What are the key differences between old and new tax regimes?
| Feature | Old Regime | New Regime |
|---|---|---|
| Tax Slabs | 3 slabs (5%, 20%, 30%) | 6 slabs (5% to 30%) |
| Basic Exemption | ₹2.5L (₹3L/₹5L for seniors) | ₹2.5L for all |
| Standard Deduction | ₹50,000 | Not available |
| 80C Deduction | ₹1.5L available | Not available |
| 80D (Medical) | Available | Not available |

The new regime offers lower rates but removes most exemptions/deductions, making it beneficial primarily for those with income above ₹15 lakh who don’t have significant deductions.
