Gig and platform worker contributions, refunds, and eligibility rules govern scheme implementation under the social security framework. The Central Government must designate an officer or agency to collect and expend contributions from aggregators, maintain the contribution in the Social Security Fund for gig and platform workers, and seek information for registration and implementation of schemes. Delayed payment attracts interest at one per cent for every month or part of a month. Aggregators must assess and pay provisional contribution in Form-XX, file a final return in Form-XXI, and may claim refund of excess contribution, to be processed electronically within ninety days. Registered workers cease to be eligible on attaining sixty years of age or after specified breaks in engagement, and aggregators must register on the designated portal.
