2) one employee join me at oct. 1, 2018 as part time and continue upto today, other employee join same job position at 1mar2019. so the one full time job commence from mar2019 to feb2020 become 12 month. my question should i write both employee actual joing date ie 1oct2018 to date and 1mar2019 to date or just claiming period (ie march2019 to feb 2020) and should i submit salary slip and PFS from oct 2018 or from march 2019?
Up to you which documents you submit - you only NEED to submit them for ANY of the 12 months.
Her joining date is still July 2018. You only need to submit documents for March2019 to Feb 2020javaidmr wrote: ↑Fri Mar 13, 2020 6:54 pm
