EPF and SOCSO contributions are linked to your employment status with a company and should not be duplicated when you switch jobs. When you resign from Company A and start working for Company B, your EPF and SOCSO contributions for the current month will be based solely on your salary from Company B. The EPF and SOCSO records are maintained separately by each company, and it is the responsibility of the employer to ensure accurate contributions. However, it is always advisable to inform both companies about your previous employment to avoid any discrepancies. Company B may request your previous EPF and SOCSO statements from Company A to make the necessary adjustments if required. This way, your EPF and SOCSO contributions will be aligned with your current employment and avoid any duplication. Companies typically have processes in place to check employees' contribution records and ensure compliance with EPF and SOCSO regulations.
