All-in-One Income Tax Calculator FY 2020-21
Module A: Introduction & Importance of Income Tax Calculator FY 2020-21
The Income Tax Calculator for Financial Year 2020-21 (Assessment Year 2021-22) is an essential financial tool that helps taxpayers estimate their tax liability under both the old and new tax regimes introduced by the Government of India. This calculator becomes particularly crucial because FY 2020-21 marked a significant transition period where taxpayers could choose between the existing tax structure with deductions and the new simplified regime with lower rates but without most exemptions.
Understanding your tax obligation is not just about compliance—it’s about strategic financial planning. The FY 2020-21 period was unique because:
- It was the first year when taxpayers could opt for the new concessional tax regime
- The budget introduced significant changes to tax slabs and rates
- Many traditional deductions (like 80C, 80D, HRA) became optional
- The standard deduction was increased to ₹50,000 for salaried individuals
According to data from the Income Tax Department, over 6.7 crore returns were filed for AY 2021-22, with approximately 30% of taxpayers opting for the new regime in its inaugural year. This calculator helps you make an informed choice between the two regimes by showing you exactly how much you would save (or pay extra) under each system.

Module G: Interactive FAQ
What was the key difference between old and new tax regimes in FY 2020-21?
The primary difference was the trade-off between lower tax rates and deductions:
- Old Regime: Higher tax rates but allowed ~70 deductions/exemptions (80C, 80D, HRA, LTA, etc.)
- New Regime: Lower tax rates but only allowed standard deduction (₹50k) and few other exemptions
The new regime introduced 6 income slabs (vs 3 in old regime) with rates ranging from 0% to 30%. The break-even point where new regime becomes better is typically around ₹15 lakh annual income, assuming standard deductions.
Could I switch between regimes every year?
For salaried individuals, the choice between regimes had to be made at the beginning of the financial year (when submitting investment declarations to employer). However, at the time of filing ITR, you could:
- Stick with the regime chosen during the year
- Or opt for the other regime (but would need to recalculate TDS)
For business professionals and freelancers, the regime choice could be made annually when filing returns. This flexibility allowed taxpayers to optimize their choice based on that year’s income and deductions.
How was the standard deduction calculated in FY 2020-21?
The standard deduction for FY 2020-21 was fixed at ₹50,000 for all salaried individuals and pensioners, regardless of their income level or actual expenses. Key points:
- Available under both old and new regimes
- Replaced the previous transport allowance (₹19,200) and medical reimbursement (₹15,000)
- No bills or proofs required to claim this deduction
- For pensioners, it replaced the previous ₹40,000 exemption on pension income
This was particularly beneficial for taxpayers who previously couldn’t claim the full transport/medical allowances due to lack of actual expenses.
What were the surcharge rates for high-income earners?
FY 2020-21 maintained the enhanced surcharge rates introduced in the previous budget:
| Income Range (₹) | Surcharge Rate | Effective Tax Rate (incl. cess) |
|---|---|---|
| 50,00,001 to 1,00,00,000 | 10% | 33% |
| 1,00,00,001 to 2,00,00,000 | 15% | 35.88% |
| 2,00,00,001 to 5,00,00,000 | 25% | 37.5% |
| Above 5,00,00,000 | 37% | 42.74% |
Note: Surcharge is calculated on the income tax amount (before cess). The 37% surcharge applied only to the super-rich (income > ₹5 crore) was a contentious issue, with many high-net-worth individuals exploring tax planning strategies to stay below this threshold.
How did the calculator handle Section 87A rebate?
The Section 87A rebate rules for FY 2020-21 were:
- Available under both old and new regimes
- Full rebate if taxable income ≤ ₹5,00,000
- Rebate amount: 100% of income tax or ₹12,500, whichever is lower
- Not available for NRIs or Hindu Undivided Families (HUFs)
Our calculator automatically applies this rebate when your taxable income is below the threshold. For example:
- If your taxable income is ₹4,80,000 and calculated tax is ₹9,600, the rebate would reduce it to ₹0
- If your income is ₹5,20,000, you would pay tax only on the excess ₹20,000
What documents should I keep for tax filing?
For smooth ITR filing for FY 2020-21, maintain these documents:
Income Proofs:
- Form 16 (from employer)
- Form 16A (for TDS on non-salary income)
- Bank statements showing interest income
- Capital gains statements from broker
- Rental income records (if applicable)
Investment Proofs:
- 80C investment certificates (PPF, ELSS, etc.)
- Medical insurance premium receipts (80D)
- Home loan interest certificate (from bank)
- Donation receipts (80G)
- Education loan interest certificate
Other Important Documents:
- PAN and Aadhaar cards
- Previous year’s ITR acknowledgment
- Form 26AS (tax credit statement)
- AIS (Annual Information Statement) from income tax portal
- Rent receipts (if claiming HRA)
Pro Tip: Organize these digitally in folders (Income, Investments, Deductions, etc.) for easy access during filing.
