The core set of documents a principal employer should collect from each contractor every month includes: (1) Monthly EPF ECR (Electronic Challan-cum-Return) copy and payment confirmation — showing individual employee UAN-wise contributions; (2) Monthly ESIC Challan copy and payment confirmation — showing individual IP-wise contributions; (3) Wage Register (Form XIV under CLRA Rules) showing individual wages paid, deductions, and net wages for the month; (4) Muster Roll (Form XIII under CLRA Rules) showing daily attendance; (5) Professional Tax deduction evidence in applicable states. At the time of initial engagement, the principal employer must hold: the contractor’s EPF establishment code and ESIC sub-code; a copy of the contractor’s CLRA Licence (Form V) — with annual renewals tracked thereafter; and confirmation of Labour Welfare Fund registration where applicable. Futurex’s onboarding checklist covers all documents required across every applicable act for the contractor’s registered state.
