Good News for those retiree’s who retired in financial year 2018-19 and afterwards. When I was filing IT return I noticed that IT department has exempted income earned by way of earned leave encashment under Section 10 (10aa) which can be claimed under column:
Less:Allowances to the extent exempt u/S 10 under sub section 10 aa. All members retired in f/y 2018-2019 are advised to note it down and claim exemption under Leave Encashment. Regarding previously retired employees can claim it after filing revised return under the guidance of CA.
Regards
I M Agrawal
