Income from Prf services

Hi Master,

i  was retainer(contract) in the company  and got income from professional services that amount was 12000rs at the end of 6 months and they transferred the same money to my current employer pf account(left the job after six months). my salary was 9000pm which is non taxable 

if i wants to reimburse pf amount  with above 12,000 amount from current employer, will they charge 30% tax for the  income from professional services of previous employer or that amount should not consider in pf

thanks

thanks
