Module G: Interactive FAQ
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 year following the FY in which you file taxes for that income.
For AY17-18, you’re filing taxes for income earned in FY16-17 (April 1, 2016 to March 31, 2017). The assessment happens in 2017-18.
Can I still file my AY17-18 return if I missed the deadline?
Yes, you can file a belated return for AY17-18, but with these consequences:
- Late filing fee of ₹5,000 (if filed after December 31, 2017 but before March 31, 2018)
- Late filing fee of ₹10,000 (if filed after March 31, 2018)
- Interest under Section 234A at 1% per month on unpaid tax
- Losses (except house property) cannot be carried forward
The last date for filing belated returns for AY17-18 was March 31, 2019. After this, you would need to file an updated return under Section 139(8A) if eligible.
How is HRA exemption calculated for AY17-18?
HRA exemption is the minimum of:
- Actual HRA received from employer
- 50% of salary (for metro cities) or 40% (for non-metro)
- Rent paid minus 10% of salary
Salary here means Basic + Dearness Allowance (if part of retirement benefits) + Commission (if fixed percentage of turnover).
Example: If your salary is ₹50,000/month (₹6,00,000/year), HRA is ₹15,000/month, and rent paid is ₹12,000/month in Mumbai:
- Actual HRA: ₹15,000 × 12 = ₹1,80,000
- 50% of salary: ₹3,00,000
- Rent paid – 10% of salary: (₹12,000 × 12) – (10% × ₹6,00,000) = ₹1,44,000 – ₹60,000 = ₹84,000
The minimum is ₹84,000, so this is your HRA exemption.
What are the consequences of not filing ITR for AY17-18?
Not filing your ITR for AY17-18 can lead to:
- Penalties: ₹5,000 if filed before December 31, 2017; ₹10,000 otherwise
- Interest: 1% per month on unpaid tax under Section 234A
- Loss Disallowance: Cannot carry forward losses (except house property)
- Refund Forfeiture: Lose any tax refund due to you
- Loan Issues: Difficulty getting loans as banks require ITR proofs
- Visa Problems: Many countries require ITRs for visa processing
- Legal Consequences: Potential prosecution for tax evasion if income exceeds basic exemption limit
Even if you have no tax liability, filing ITR creates a financial record that can be useful for future transactions.
How do I claim deductions for home loan interest in AY17-18?
For AY17-18, home loan interest deductions are available under two sections:

How does the calculator handle income from multiple sources?
This calculator is designed for ITR-1 filers, so it handles:
- Salary Income: Includes basic, allowances, perquisites, and profit in lieu of salary
- House Property Income: Net annual value (after 30% standard deduction and interest on home loan)
- Other Sources: Includes:
- Interest income (savings bank, fixed deposits)
- Dividend income
- Family pension
- Gifts (taxable if above ₹50,000 from non-relatives)
For each income source:
- Enter the gross amount before any deductions
- The calculator will apply standard deductions where applicable (like 30% for house property)
- Then it will apply your claimed deductions (80C, 80D, etc.)
- Finally, it calculates tax on the net taxable income
If you have income from capital gains, business/profession, or more than one house property, you cannot use ITR-1 and should use other ITR forms.
For official guidelines, refer to the Income Tax Department’s ITR preparation utility and the IRS international tax comparisons for global context.
