advance income tax in case of losses

no

No, it is not mandatory.

Advance Tax needs to be paid only if your expected tax liability is more than Rs.5000.

According to Section 208 of IT Act Advance tax shall be payable during a financial year in every case where the amount of such tax payable by the assessee during that year, as computed in accordance with the provisions of this Chapter, is ⁴⁷[five thousand] rupees or more.]
