Dear Ramasu: PF contribution is payable on the basis of basic wages, dearness allowance and
retaining allowance (if any)] actually drawn during the whole month. An employee may not attend work but he is on paid leave and so his wages are drawn, the PF contribution is to be paid (Clause 29(3) of EPF Scheme. But if it is unpaid leave or absence without leave then no wages are drawn, then there will be no liability to pay PF.
