Calculate your income tax liability under both old and new tax regimes for FY 2020-21 (AY 2021-22).
Comprehensive Guide to Income Tax Calculation for FY 2020-21
Module A: Introduction & Importance of Income Tax Calculator 2020-21
The Income Tax Calculator for FY 2020-21 (AY 2021-22) is an essential financial tool that helps taxpayers determine their exact tax liability under both the old and new tax regimes introduced by the Government of India. This fiscal year marked a significant shift in India’s taxation landscape with the introduction of an optional new tax regime offering lower rates but without most exemptions and deductions.
Understanding your tax liability is crucial for:
- Accurate financial planning and budgeting
- Making informed decisions about investments and deductions
- Choosing between the old and new tax regimes
- Ensuring compliance with Income Tax Department requirements
- Optimizing your tax savings legally
The Union Budget 2020 introduced the new tax regime under Section 115BAC of the Income Tax Act, giving taxpayers the option to choose between the existing system with exemptions/deductions and a simplified system with lower rates. This calculator helps you compare both options side-by-side to make the optimal choice for your financial situation.

1. Old Tax Regime Calculation
The old regime follows these steps:
-
Gross Total Income:
Sum of all income heads (salary, house property, business, capital gains, other sources)
-
Less: Deductions under Chapter VI-A:
Subtract eligible deductions under Sections 80C to 80U (common ones: 80C, 80D, 80G, etc.)
-
Less: Standard Deduction:
₹50,000 for salaried individuals/pensioners
-
Taxable Income:
Result after all exemptions and deductions
-
Tax Calculation:
Income Range (₹) Below 60 years 60-80 years Above 80 years Up to 2,50,000 Nil 2,50,001 – 5,00,000 5% Nil Nil 5,00,001 – 10,00,000 20% 20% Nil Above 10,00,000 30% -
Surcharge:
Applied on income tax (not cess) for high incomes:
- 10% if total income > ₹50 lakh
- 15% if total income > ₹1 crore
- 25% if total income > ₹2 crore

- Below ₹7,50,000, old regime is usually better
-
Consider Business Expenses:

General Tips for All Taxpayers:
- File ITR even if income is below taxable limit to maintain financial records

Module G: Interactive FAQ – Your Tax Questions Answered
1. Can I switch between old and new tax regimes every year?
For salaried individuals, the choice between old and new regimes must be made at the beginning of the financial year and communicated to the employer. However, at the time of filing ITR, you can choose differently from what was communicated to your employer.
For business professionals, once you opt for the new regime (Section 115BAC), you cannot switch back to the old regime in subsequent years, except in specific cases where your business income ceases.
Important: The Budget 2023 made the new regime the default option, but you can still choose the old regime if it’s more beneficial.
2. What are the key deductions I lose in the new tax regime?
In the new tax regime, you cannot claim most deductions and exemptions, including:
- Standard deduction of ₹50,000
- Section 80C deductions (PPF, LIC, ELSS, etc.)
- Section 80D (Medical insurance premiums)
- House Rent Allowance (HRA)
- Leave Travel Allowance (LTA)
- Interest on home loan (Section 24)
- Education loan interest (Section 80E)
- Donations to charitable institutions (Section 80G)
However, you can still claim:
- Employer’s contribution to NPS (80CCD(2))
- Deduction for employment of new employees (80JJAA)
- Transport allowance for differently-abled
- Conveyance allowance for expenditure incurred
3. How does the calculator handle surcharge and cess?
Our calculator automatically applies surcharge and cess based on your total income:
- Surcharge: Applied on the income tax amount (before cess)
- 10% if total income > ₹50,00,000
- 15% if total income > ₹1,00,00,000
- 25% if total income > ₹2,00,00,000
- 37% if total income > ₹5,00,00,000
- Health & Education Cess: 4% of (Income Tax + Surcharge)
For example, if your income tax is ₹5,00,000 and your total income is ₹60,00,000:
- Surcharge: 10% of ₹5,00,000 = ₹50,000
- Cess: 4% of (₹5,00,000 + ₹50,000) = ₹22,000
- Total tax: ₹5,00,000 + ₹50,000 + ₹22,000 = ₹5,72,000
Note: The surcharge rates were revised in Budget 2023, but our calculator uses the 2020-21 rates.
4. What documents do I need to use this calculator effectively?
To get the most accurate results from this calculator, gather these documents:

- The official tax slabs for both old and new regimes
- Correct surcharge and cess calculations
- Age-based exemption limits
- Section 87A rebate rules

6. Can I use this calculator for previous or future financial years?
This calculator is specifically designed for FY 2020-21 (AY 2021-22) and incorporates:
- The tax slabs introduced in Budget 2020
- The new optional tax regime (Section 115BAC)

For other financial years:
- FY 2021-22: Similar to 2020-21 but with slight adjustments to the new regime
- FY 2022-23: New regime became more attractive with standard deduction
- FY 2023-24: New regime became default with revised slabs
Key changes in subsequent years:
| Year | Key Change |
|---|---|
| 2021-22 | No major changes from 2020-21 |
| 2022-23 | Standard deduction of ₹50,000 introduced in new regime |
| 2023-24 | New regime became default; rebate limit increased to ₹7,00,000 |
For accurate calculations for other years, you would need a calculator updated with those specific rules.
7. What should I do if the calculator shows I owe more tax than expected?
If our calculator shows a higher tax liability than you expected, follow these steps:
- Double-check your inputs:
- Verify your total income figure
- Ensure you’ve selected the correct age group
- Confirm you’ve entered all eligible deductions
- Check that you’ve selected the correct tax regime
- Review your deductions:
- Are you claiming all eligible 80C investments?
- Have you included HRA if you pay rent?
- Have you accounted for medical insurance premiums?
- Are there any business expenses you can claim?
- Consider regime switching:
- Try calculating with both old and new regimes
- The regime that’s better can change based on your income level
- High-income earners often benefit from the new regime
- Middle-income earners with deductions often prefer the old regime
- Check for advance tax liability:
- If your tax liability exceeds ₹10,000, you may need to pay advance tax
- Advance tax deadlines: 15 June, 15 Sept, 15 Dec, 15 March
- Interest under Section 234B/C applies for late payments
- Consult a professional:
- If the discrepancy is large, consult a CA
- They can identify deductions you might have missed
- They can help with tax planning for future years
- Verify with official tools:
- Use the Income Tax Department’s calculator
- Check your Form 26AS for TDS credits
- Review your Form 16 carefully
Remember: It’s better to discover a higher tax liability now than to receive a notice from the IT department later!
