Module C: Formula & Methodology
The calculator uses the official income tax computation methodology prescribed by the Income Tax Department for FY 2018-19. Here’s the step-by-step calculation process:
-
Gross Total Income (GTI):
GTI = Income from Salary + House Property + Business/Profession + Capital Gains + Other Sources
-
Total Deductions:
Total Deductions = (80C + 80D + HRA + Other Deductions)
Note: 80C limited to ₹1,50,000; 80D limited to ₹50,000 (₹25,000 self + ₹25,000 parents)
-
Taxable Income:
Taxable Income = GTI – Total Deductions – Standard Deduction (₹40,000 for salaried)
-
Tax Calculation:
Income Range Below 60 60-80 Years Above 80 Up to ₹2,50,000 Nil Up to ₹3,00,000: Nil Up to ₹5,00,000: Nil ₹2,50,001 – ₹5,00,000 5% ₹3,00,001 – ₹5,00,000: 5% ₹5,00,001 – ₹10,00,000: 20% ₹5,00,001 – ₹10,00,000 20% 20% ₹10,00,001+: 30% Above ₹10,00,000 30% 30% 30% -
Surcharge:
10% of income tax if total income > ₹50 lakh
15% of income tax if total income > ₹1 crore
-
Education Cess:
3% of (Income Tax + Surcharge)
-
Rebate u/s 87A:
₹2,500 or tax amount (whichever is lower) if taxable income ≤ ₹3,50,000

Module G: Interactive FAQ
What is the last date for filing ITR for FY 2018-19?
The original due date for filing ITR for FY 2018-19 (AY 2019-20) was July 31, 2019 for most taxpayers. However, the department extended it to August 31, 2019 for certain categories.
For belated returns, you could file until March 31, 2020 with a late fee of ₹5,000 (₹1,000 if income ≤ ₹5 lakh). After this date, you would need to file an updated return under Section 139(8A) if eligible.
Note: As of 2023, you can still file a belated return for FY 2018-19, but you’ll need to pay the applicable late fees and interest.
How is HRA exemption calculated for FY 2018-19?
HRA exemption is the minimum of these three amounts:
- Actual HRA received from employer
- 50% of salary (for metro cities) or 40% (for non-metros)
- Actual rent paid minus 10% of salary
Example: If your salary is ₹60,000/month, HRA is ₹20,000, and rent paid is ₹15,000 in Delhi:
- Actual HRA: ₹20,000
- 50% of salary: ₹30,000
- Rent paid – 10% salary: ₹15,000 – ₹6,000 = ₹9,000
- Exemption: ₹9,000 (minimum of above)
For accurate calculation, use our HRA calculator within the main tool.
What are the tax implications of selling property in FY 2018-19?
Property sales in FY 2018-19 attract capital gains tax, which depends on the holding period:
Short-Term Capital Gains (holding ≤ 24 months):
- Taxed at your applicable income tax slab rate
- No indexation benefit
- Can be set off against short-term capital losses
Long-Term Capital Gains (holding > 24 months):
- Taxed at 20% with indexation benefit
- Indexation adjusts purchase price for inflation using Cost Inflation Index (CII)
- CII for FY 2018-19: 280 (base year 2001-02 = 100)
- Can claim exemption by reinvesting in:
- Residential property (Section 54) – within 1 year before or 2 years after sale
- Capital gains bonds (Section 54EC) – within 6 months (max ₹50 lakh)
Example: Property bought in 2010-11 (CII 167) for ₹30 lakh, sold in 2018-19 for ₹1 crore:
- Indexed cost = ₹30,00,000 × (280/167) = ₹50,54,485
- LTCG = ₹1,00,00,000 – ₹50,54,485 = ₹49,45,515
- Tax = 20% of ₹49,45,515 = ₹9,89,103
Can I revise my ITR for FY 2018-19 now in 2023?
Yes, you can still revise your ITR for FY 2018-19 under certain conditions:
Original Filing:
- If you filed your return by the due date (July 31, 2019), you could revise it until March 31, 2020
- After this date, revisions weren’t normally allowed
Current Options (2023):
- Updated Return (Section 139(8A)): Introduced in Budget 2022, allows filing updated returns within 24 months from the end of the relevant assessment year
- For FY 2018-19, you can file until March 31, 2024
- Additional tax of 25% (50% if filed after 12 months) on tax payable
- Rectification: If there’s a mistake in processing, you can file a rectification request
- Belated Return: If you didn’t file originally, you can file a belated return with late fees
Important: Consult a tax professional before filing an updated return, as it may trigger scrutiny for previous discrepancies.
What documents should I keep for FY 2018-19 tax records?
Maintain these documents for at least 6 years from the end of the assessment year (until March 31, 2025):
Income Documents:
- Form 16 (for salaried individuals)
- Form 16A (for TDS on non-salary income)

How does the standard deduction work for pensioners in FY 2018-19?
For FY 2018-19, pensioners received the same standard deduction benefits as salaried individuals:
- Amount: ₹40,000 or the pension amount, whichever is lower
- Eligibility: Available to all pensioners, regardless of age
- Nature: Flat deduction from pension income (no need for actual expenses)
- Interaction with other deductions:
- Can be claimed along with 80C, 80D, etc.
- Doesn’t affect medical reimbursement (if any)
Example: Mr. Sharma receives a monthly pension of ₹30,000 (₹3,60,000 annually):
- Standard deduction: ₹40,000 (limited to pension amount)
- Taxable pension income: ₹3,60,000 – ₹40,000 = ₹3,20,000
- If he has other income (e.g., interest), it gets added to this
Special Cases:
- Family pension: Standard deduction is ₹15,000 or 1/3 of pension, whichever is lower
- Commutation of pension: 1/3 of commuted value is tax-free for government employees
What are the consequences of not filing ITR for FY 2018-19?
Failing to file your ITR for FY 2018-19 can have several serious consequences:
Immediate Penalties:
- Late filing fee (Section 234F):
- ₹5,000 if filed after due date but before Dec 31, 2019
- ₹10,000 if filed after Dec 31, 2019
- ₹1,000 if total income ≤ ₹5 lakh
- Interest (Section 234A): 1% per month on outstanding tax
Long-Term Consequences:
- Loss Adjustment: Cannot carry forward losses (except house property)
- Loan Applications: Banks may reject loan applications without ITR
- Visa Issues: Many countries require tax returns for visa processing
- Legal Problems: May face prosecution for tax evasion if income exceeds basic exemption
- Refund Forfeiture: Lose right to claim tax refunds
Special Cases:
- If you have TDS deducted but didn’t file ITR, you can still file to claim refund
- For business income, non-filing may lead to presumptive taxation in future years
- If you have foreign assets, non-filing attracts much harsher penalties
Solution: File a belated return immediately. While you’ll pay late fees and interest, it’s better than the long-term consequences of not filing.
