Formula & Methodology Behind the Tax Calculation
1. Gross Total Income Calculation
The calculator first determines your Gross Total Income (GTI) by summing:
GTI = Salary + House Property + Capital Gains + Business Income + Other Sources
2. Deductions Under Chapter VI-A
For the old regime, the following deductions are applied:
Total Deductions = Standard Deduction (₹50,000)
+ 80C (Max ₹1,50,000)
+ 80D (Max ₹25,000/₹50,000)
+ HRA (Minimum of:
- Actual HRA received
- 50% of salary (metro)/40% (non-metro)
- Rent paid minus 10% of salary)
+ Other eligible deductions (80G, 80E, etc.)
3. Taxable Income Determination
Taxable Income = GTI - Total Deductions
4. Income Tax Calculation
Old Regime Slabs (AY 2020-21):
| Income Range | Below 60 | 60-80 years | Above 80 |
|---|---|---|---|
| Up to ₹2,50,000 | Nil | ||
| ₹2,50,001 – ₹5,00,000 | 5% | Nil | |
| ₹5,00,001 – ₹10,00,000 | 20% | 20% | Nil |
| Above ₹10,00,000 | 30% | ||
New Regime Slabs (AY 2020-21):
| Income Range | Tax Rate |
|---|---|
| Up to ₹2,50,000 | Nil |
| ₹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% |
5. Surcharge Calculation
For income exceeding ₹50 lakh:
- 10% surcharge: ₹50L – ₹1Cr
- 15% surcharge: ₹1Cr – ₹2Cr
- 25% surcharge: ₹2Cr – ₹5Cr
- 37% surcharge: Above ₹5Cr
6. Health & Education Cess
Cess = 4% of (Income Tax + Surcharge)
7. Tax Rebate (Section 87A)
Old Regime: ₹2,500 rebate if taxable income ≤ ₹3,50,000
New Regime: Full tax rebate if taxable income ≤ ₹5,00,000
8. Final Tax Liability
Total Tax = (Income Tax + Surcharge + Cess) - Rebate
Our calculator implements these exact formulas with precision, including all edge cases like marginal relief for surcharge calculations. The methodology follows the Income Tax Department’s official guidelines for AY 2020-21.

Interactive FAQ: Tax Calculation for AY 2020-2021
What is the difference between Financial Year and Assessment Year?
The Financial Year (FY) is the 12-month period from April 1 to March 31 in which you earn income. The Assessment Year (AY) is the following 12-month period in which you file taxes for that income.
Example: For income earned between April 1, 2019 and March 31, 2020 (FY 2019-20), you file taxes in AY 2020-21 (April 1, 2020 to March 31, 2021).
This distinction is crucial because tax rules can change between assessment years, even for the same financial year’s income.
Can I switch between old and new tax regimes every year?
For AY 2020-21, taxpayers had a one-time choice between regimes when filing their return. However, there are important considerations:
- Salaried individuals must inform their employer at the start of the financial year about their regime choice for TDS purposes
- Business professionals can choose annually when filing ITR
- Once you opt for the new regime and claim certain exemptions (like for employer contributions to NPS), you cannot switch back to the old regime in subsequent years
- The choice impacts your entire income, not just salary
We recommend using our calculator to compare both regimes before making your final decision.
How is surcharge calculated and when does it apply?
Surcharge is an additional tax on high-income individuals, calculated as a percentage of the income tax (before cess). For AY 2020-21:
| Income Range | Surcharge Rate | Marginal Relief |
|---|---|---|
| ₹50,00,001 to ₹1,00,00,000 | 10% | If surcharge > (Income – ₹50L), limited to the difference |
| ₹1,00,00,001 to ₹2,00,00,000 | 15% | If surcharge > (Income – ₹1Cr), limited to the difference |
| ₹2,00,00,001 to ₹5,00,00,000 | 25% | If surcharge > (Income – ₹2Cr), limited to the difference |
| Above ₹5,00,00,000 | 37% | If surcharge > (Income – ₹5Cr), limited to the difference |
Example: For income of ₹51,00,000 with tax of ₹13,50,000:
- Normal surcharge: 10% of ₹13,50,000 = ₹1,35,000
- Marginal relief: ₹51,00,000 – ₹50,00,000 = ₹1,00,000
- Actual surcharge: ₹1,00,000 (lower of the two)
Our calculator automatically applies marginal relief where applicable.
What documents should I keep for tax filing in AY 2020-21?
Maintain these essential documents:
Income Proof:
- Form 16 (for salaried individuals)
- Form 16A (for TDS on other incomes)
- Bank statements showing interest income

Other Documents:

Digital copies are acceptable, but ensure they’re clearly legible. The Income Tax Department may request these during assessment.
How does the calculator handle income from multiple sources?
Our calculator is designed to handle composite income from various sources:
- Salary Income: Includes basic, DA, bonuses, and all allowances. HRA is separately considered for exemption.
- House Property: Net annual value (rent received minus municipal taxes minus 30% standard deduction minus home loan interest).
- Capital Gains:
- Short-term: Added to total income (STCG on equity taxed at 15%)
- Long-term: 20% with indexation (10% without indexation for listed securities)
- Business/Profession: Net profit after all allowable expenses and depreciation.
- Other Sources: Interest income, dividends, winnings, etc. (Note: Dividend income was taxable in AY 2020-21 at slab rates).
The calculator:
- Aggregates all income sources to compute Gross Total Income
- Applies appropriate deductions for each income type
- Considers set-off and carry-forward rules for losses
- Calculates tax on the aggregated taxable income
For complex situations with multiple capital gains or foreign income, we recommend consulting a tax professional for precise calculations.
