Few points that I would like to clarify
1) FY 2019-20 closure date if 31st March 2020 only. There is no extension of that date. Please keep it in mind
2) Belated returns or Revised returns for the FY 2018-19 can be filed till 30th June.
3) Deductions under 80C that is insurance, house loan principal repayment, ppf investment, 80D that is mediclaim and health insurance etc. can be claimed by investing till 30th June. Government has extended this date by 3 months.
4) New LIC, mediclaim, PPF, NPS, etc. policies taken till 30th June will be eligible for the deduction for the FY 2019-20.
5) Housing loan interest is eligible for deduction on accrual basis, so interest accrued till 31st March will be eligible for the deduction in FY 2019-20. However Installments due upto 31st March can be claimed as deduction ever if paid till 30th June.
Please call or write in the comments if you have any query.
