Module A: Introduction & Importance of Income Tax Calculation for FY 2017-18
The calculation of income tax for financial year 2017-18 remains critically important for several reasons despite being several years past.

Understanding your tax liability from this period is essential for:
- Retroactive Compliance: Many taxpayers still receive notices or need to file revised returns for this assessment year (AY 2018-19).

The Income Tax Act, 1961 governs these calculations, with specific provisions that were applicable during this financial year. The Income Tax Department’s official website maintains archives of all circulars and notifications from this period.

Module G: Interactive FAQ About FY 2017-18 Income Tax
What was the last date for filing ITR for FY 2017-18 (AY 2018-19)?
The original due date for filing income tax returns for FY 2017-18 was July 31, 2018 for most taxpayers. However, the Income Tax Department extended this deadline to August 31, 2018 for all taxpayers except those requiring audit.
For taxpayers subject to audit (businesses/professions with turnover > ₹1 crore), the due date was September 30, 2018, which was later extended to October 15, 2018.
Belated returns could be filed until March 31, 2019 with a late fee of ₹5,000 (₹1,000 if income < ₹5 lakh).
How was long-term capital gains taxed in FY 2017-18 compared to now?
FY 2017-18 had significantly different capital gains tax rules:
| Asset Type | FY 2017-18 Rules | Current Rules (FY 2023-24) |
|---|---|---|
| Equity Shares/Equity MF | Tax-free (no LTCG tax) | 10% on gains > ₹1L (without indexation) |
| Debt MF | 20% with indexation | Taxed as per slab rates (no indexation) |
| Property | 20% with indexation | 20% with indexation |
| Gold | 20% with indexation | Taxed as per slab rates |
| Holding Period (LTCG) | 12 months for most assets | 12 months (equity), 36 months (others) |
The FY 2017-18 rules were particularly advantageous for equity investors as all long-term capital gains from equity shares and equity-oriented mutual funds were completely tax-exempt regardless of the amount.
Can I still file a revised return for FY 2017-18 in 2024?
No, you can no longer file a revised return for FY 2017-18 (AY 2018-19). The time limit for revising returns is:
- Within 1 year from the end of the relevant assessment year, or
- Before the completion of assessment (whichever is earlier)
For AY 2018-19, this deadline expired on March 31, 2020. However, you may still:
- File an updated return under Section 139(8A) (introduced in Budget 2022) within 24 months from the end of the relevant AY (until March 31, 2021 for AY 2018-19) – this window has also closed
- Respond to any notices from the Income Tax Department if you receive one
- Maintain all records until March 2024 (6 years from the end of AY 2018-19) in case of any inquiries
For genuine cases with tax demands, you may need to approach the department through proper channels with a valid reason for the delay.
What were the standard deduction rules for salaried employees in FY 2017-18?
FY 2017-18 was the last year before the standard deduction was reintroduced in Budget 2018 (effective FY 2018-19). During FY 2017-18, salaried employees could claim:
