Can not understand the question. What do you mean by leave salary? Do you mean extra salary drawn by you? If you want to refund extra salary, then you must fill up TR 7 Form. You ask your DI (office) in which account head you will submit the amount.
I have tried to say leave encashment for state govt. employee after retirement. However I have solved the problem by myself and like to say all that Leave encashment bill (Leave Salary) bill will draw through e-billing TR-50 Form at present. thanks to all for response.
