Tax Calculation Assessment Year 2020-21
Module A: Introduction & Importance of Tax Calculation Assessment Year 2020-21
The Assessment Year (AY) 2020-21 refers to the period from April 1, 2020 to March 31, 2021 during which the income earned in the previous Financial Year (FY) 2019-20 is assessed and taxed. This was a particularly significant year due to several economic factors including the global pandemic’s impact on personal finances and government revenue.
Understanding your tax liability for AY 2020-21 is crucial because:
- It was the first year when taxpayers could choose between the old and new tax regimes introduced in Budget 2020
- The government offered several pandemic-related tax relief measures that could significantly reduce your liability
- Proper calculation helps avoid interest penalties for underpayment or overpayment of taxes
- Accurate assessment is essential for financial planning and investment decisions
The Income Tax Act, 1961 governs all tax calculations for this period. According to data from the Income Tax Department, over 6.5 crore returns were filed for AY 2020-21, with the new tax regime being chosen by approximately 12% of taxpayers in its inaugural year.

Module G: Interactive FAQ About AY 2020-21 Tax Calculation
What was the last date for filing ITR for AY 2020-21?
The original due date was July 31, 2020, but it was extended multiple times due to COVID-19. The final extended deadline was:
- December 31, 2020: For most taxpayers
- February 15, 2021: For taxpayers requiring audit
- March 31, 2021: Final extended date for all taxpayers
Late filings could be done until March 31, 2022 with penalties.
Could I switch between old and new tax regimes for AY 2020-21?
Yes, AY 2020-21 was unique because:
- You could choose between regimes each year (unlike subsequent years where business income taxpayers lost this flexibility)
- The choice had to be made before filing the return – you couldn’t claim deductions and then switch to new regime
- For salaried employees, the choice had to be communicated to the employer at the start of the financial year (FY 2019-20) for correct TDS deduction
Our calculator lets you compare both regimes side-by-side to make the optimal choice.
How was capital gains tax calculated in AY 2020-21?
Capital gains tax remained unchanged from previous years:
Short-Term Capital Gains (STCG):
- Equity/Equity MF: 15% if sold within 1 year
- Debt/Non-Equity: Added to income and taxed at slab rate
Long-Term Capital Gains (LTCG):
- Equity/Equity MF: 10% on gains > ₹1 lakh (without indexation)
- Debt/Property: 20% with indexation benefit
- Indexation: Used Cost Inflation Index (CII) of 289 for FY 2019-20
Example: If you sold property bought in 2010-11 (CII: 167) for ₹80 lakh in FY 2019-20:
Indexed Cost = Original Cost × (289/167)
LTCG = Sale Price – Indexed Cost
Tax = 20% of LTCG
What were the special COVID-19 tax relief measures for AY 2020-21?
The government introduced several relief measures:

How was rental income taxed in AY 2020-21?
Rental income from house property was taxed as follows:
Calculation Steps:
-
Gross Annual Value (GAV):
Higher of:
- Actual rent received
- Expected rent (based on municipal value)
-
Deductions Allowed:
- 30% of GAV (standard deduction)
- Property tax paid
- Interest on home loan (up to ₹2 lakh for self-occupied)
-
Net Taxable Income:
GAV – Deductions
Special Cases:
-
Self-Occupied Property:
Deemed to have nil annual value (no tax if not rented out)
-
Multiple Properties:
Only one property can be treated as self-occupied; others are deemed rented
-
Joint Ownership:
Income is taxed in proportion to ownership share
Example: If you received ₹3,60,000 annual rent and paid ₹30,000 property tax with ₹1,80,000 home loan interest:
Taxable Income = ₹3,60,000 – 30% (₹1,08,000) – ₹30,000 – ₹1,80,000 = ₹42,000
What were the penalties for late filing in AY 2020-21?
The penalties under Section 234F were:
| Filing Date | Income ≤ ₹5 lakh | Income > ₹5 lakh |
|---|---|---|
| By December 31, 2020 | No penalty | No penalty |
| After December 31, 2020 but before March 31, 2021 | ₹1,000 | ₹5,000 |
| After March 31, 2021 | ₹5,000 | ₹10,000 |
Additional Consequences:
- Losses (except house property) couldn’t be carried forward
- Interest under Section 234A (1% per month) on tax due
- Delayed refund processing
However, the CBDT waived penalties for taxpayers filing by March 31, 2021 due to COVID-19 hardships.
