Income Tax Calculator for Individual (AY 2020-21)
Accurately calculate your tax liability under both old and new tax regimes with rebates, deductions, and cess for Assessment Year 2020-21
Module A: Introduction & Importance of Income Tax Calculator for AY 2020-21
The Income Tax Calculator for Assessment Year 2020-21 is an essential financial tool designed to help Indian taxpayers accurately determine their tax liability under both the old and new tax regimes introduced in the Union Budget 2020. This financial year (FY 2019-20) marked a significant shift in India’s taxation landscape with the introduction of optional lower tax rates without most exemptions and deductions.
Why This Calculator Matters
- Regime Comparison: The calculator provides side-by-side comparison between the old regime (with deductions) and new regime (lower rates without most deductions)
- Rebate Calculation: Automatically applies Section 87A rebate for incomes up to ₹5 lakh (increased from ₹3.5 lakh in previous years)
- Age-Specific Slabs: Accounts for different tax slabs based on age groups (below 60, 60-80, above 80)
- Cess Calculation: Includes the 4% Health and Education Cess introduced in Budget 2018
- Financial Planning: Helps in tax planning by showing potential savings under different scenarios
According to Income Tax Department data, over 5.89 crore income tax returns were filed for AY 2020-21, with the new tax regime being opted by approximately 12% of taxpayers in its first year of implementation.
Module B: How to Use This Income Tax Calculator
Follow these step-by-step instructions to get accurate tax calculations for AY 2020-21:
-
Enter Your Total Income:
- Include all sources: salary, business income, capital gains, house property, and other sources

- For salaried individuals, this is typically the amount in Form 16 Part B under “Gross Salary”
-
Select Your Age Group:
- Below 60 years: Standard tax slabs apply
- 60-80 years: Higher basic exemption limit of ₹3,00,000
- Above 80 years: Highest basic exemption limit of ₹5,00,000
-
Choose Tax Regime:
- Old Regime: Allows deductions under Sections 80C, 80D, HRA, home loan interest, etc.
- New Regime: Lower tax rates but without most deductions (except 80CCD(2) and 80JJAA)
-
Enter Deductions:
- For old regime: Enter total deductions under Chapter VI-A (80C, 80D, 80G, etc.)
- Common deductions include:
- 80C: LIC, PPF, ELSS, tuition fees (max ₹1,50,000)
- 80D: Medical insurance (max ₹25,000 for self, ₹50,000 for senior citizens)
- HRA: House Rent Allowance exemption
- 24(b): Home loan interest (max ₹2,00,000)
-
Review Results:
- The calculator shows taxable income after deductions
- Displays income tax before and after cess
- Compares both regimes to show which is more beneficial
- Shows applicable rebate under Section 87A
For salaries above ₹15 lakh, the old regime is typically more beneficial due to higher deductions. For incomes below ₹10 lakh, compare both regimes carefully as the new regime might offer lower taxes without the hassle of maintaining investment proofs.

Calculation Methodology
-
Taxable Income Calculation:
- Old Regime: Taxable Income = Gross Income – Deductions (80C, 80D, HRA, etc.) – Exemptions
- New Regime: Taxable Income = Gross Income (most deductions not allowed)
-
Tax Computation:
- Apply appropriate tax slab rates to taxable income
- Add 4% Health & Education Cess on income tax
- Apply Section 87A rebate if applicable (full rebate for income ≤ ₹5,00,000)
-
Rebate under Section 87A:
- Maximum rebate: ₹12,500 (for income ≤ ₹5,00,000)
- Rebate = 100% of income tax or ₹12,500, whichever is lower
- Available under both regimes
-
Surcharge (for high incomes):
- 10% surcharge for income > ₹50 lakh
- 15% surcharge for income > ₹1 crore
- 25% surcharge for income > ₹2 crore
- 37% surcharge for income > ₹5 crore
Mathematical Formulas
The calculator uses these precise formulas:
Old Regime:
Taxable Income = Gross Income - Standard Deduction (₹50,000) - HRA - 80C - 80D - Other Deductions
Income Tax = (Taxable Income × Slab Rate) - Rebate
Total Tax = (Income Tax + Surcharge) × 1.04 (for cess)
New Regime:
Taxable Income = Gross Income - Standard Deduction (₹50,000) [only if opted]
Income Tax = (Taxable Income × New Slab Rates) - Rebate
Total Tax = (Income Tax + Surcharge) × 1.04 (for cess)
The standard deduction of ₹50,000 was introduced in Budget 2018 to replace transport allowance (₹19,200) and medical reimbursement (₹15,000). This is automatically applied in the old regime but optional in the new regime.

Key Observations from AY 2020-21 Data
- Only 1.5% of taxpayers earned above ₹20 lakh but contributed 62% of total personal income tax
- The new tax regime was opted by approximately 12% of taxpayers in its first year
- Average tax paid by taxpayers in the ₹10-20 lakh bracket was ₹75,000 (about 5% of their income)
- 55% of taxpayers had income below the basic exemption limit of ₹2.5 lakh
- Refunds issued increased by 34.5% compared to previous year, indicating better compliance
The introduction of the new tax regime in Budget 2020 created a dual taxation system where taxpayers could choose between lower rates without exemptions or higher rates with exemptions. Economic Survey 2020-21 noted that this choice led to behavioral changes in tax planning, with many taxpayers in the ₹5-10 lakh bracket opting for the new regime.

Module G: Interactive FAQ
What is the last date for filing ITR for AY 2020-21?
The original due date for filing Income Tax Return (ITR) for AY 2020-21 (FY 2019-20) was November 30, 2020 for most taxpayers. However, due to COVID-19, the government extended this deadline multiple times:
- First extension: December 31, 2020
- Second extension: January 10, 2021
- Final extension: March 31, 2021 (for most taxpayers)
For taxpayers requiring audit (businesses/professionals with turnover > ₹1 crore or income > ₹50 lakh), the due date was extended to February 15, 2021.
Note: Even though the filing deadline has passed, you can still file a belated return until March 31, 2022 (with late fees if applicable).
Can I switch between old and new tax regimes every year?
For salaried individuals and pensioners:
- You can choose between regimes every financial year
- Your choice doesn’t lock you in for future years
- You must inform your employer about your regime choice at the beginning of the financial year (Form 10IE)
For businesses and professionals:
- Once you opt for the new regime, you’re locked in for that business permanently
- You cannot switch back to the old regime in subsequent years
- This rule applies to business income reported under “Profits and Gains from Business or Profession”
Important Note: If you have both salary and business income, you can choose different regimes for each income source, but this requires careful tax planning.
How is the standard deduction of ₹50,000 applied in both regimes?
The standard deduction works differently in each regime:
Old Regime:
- Automatically applied to all salaried individuals and pensioners
- Replaces the previous transport allowance (₹19,200) and medical reimbursement (₹15,000)
- Reduces your taxable income by ₹50,000
- No documentation or proof required
New Regime:
- Not automatically applied – you must explicitly choose to claim it
- If claimed, reduces taxable income by ₹50,000
- This is one of the few deductions allowed in the new regime
- Must be declared in your ITR if you want to claim it
Example: For a salary of ₹8,00,000:
- Old regime: Taxable income = ₹7,50,000 (after standard deduction)
- New regime: Taxable income = ₹8,00,000 (unless you opt for standard deduction)
Pro Tip: In the new regime, always opt for the standard deduction as it’s one of the few ways to reduce your taxable income.
What is Section 87A rebate and how does it work in AY 2020-21?
Section 87A provides a tax rebate to individual taxpayers with income below certain thresholds. For AY 2020-21:
- Maximum rebate amount: ₹12,500
- Eligibility: Available to resident individuals only
- Income limit: Total income after deductions must be ≤ ₹5,00,000
- Application: The rebate is equal to 100% of your income tax or ₹12,500, whichever is lower
How It Works:
- Calculate your total income after all deductions
- Compute income tax on this amount
- If total income ≤ ₹5,00,000, subtract the rebate from your tax
- If the rebate exceeds your tax, you pay zero tax
Example 1 (Income ₹4,50,000):
- Income tax: ₹12,500 (5% of ₹2,50,000 above exemption limit)
- Rebate: ₹12,500 (full rebate)
- Final tax: ₹0
Example 2 (Income ₹5,20,000):
- Income tax: ₹13,000 (5% of ₹2,70,000 above exemption limit)
- Rebate: ₹0 (income exceeds ₹5,00,000 limit)
- Final tax: ₹13,000 + 4% cess = ₹13,520
Important: The rebate is applied before adding health and education cess. So if your tax before cess is ₹10,000, you’ll pay zero tax (₹10,000 rebate), but if it’s ₹13,000, you’ll pay ₹500 tax plus 4% cess.
