Employer application for inapplicability of social security provisions requires employee consent, compliance clearance, and time-bound decision. An employer may apply electronically to have Chapter III or Chapter IV made inapplicable to an establishment, provided the employer and the majority of employees agree in writing. The application must be decided within sixty days, failing which permission is deemed granted from the expiry of that period. No application lies after subsequent coverage, before five years of coverage, or unless all returns are furnished, all dues are paid, and self-certification is submitted.
