Employers in Cambodia must manage NSSF (National Social Security Fund) contributions covering three mandatory schemes: Occupational Risk at 0.8% (fully employer-funded); Healthcare at 2.6% (statutorily split as 1.3% employer and 1.3% employee); and the Pension scheme at a rate of 4% total (2% employer and 2% employee) for the initial five-year phase. Contributions are calculated based on the employee's monthly wage, subject to a statutory cap of KHR 1,200,000, and must be submitted monthly by the 15th of the following month. Employers must also withhold progressive Tax on Salary (ToS) and remit it to the General Department of Taxation (GDT) via the E-Filing system. Compliance with the national minimum wage order is also mandatory.

Yes. Employers must withhold Tax on Salary (ToS) monthly from employee compensation and remit it to the GDT via the E-Filing platform by the 25th of the following month. Progressive tax rates apply: 0% for monthly income up to KHR 1.5 million, 5% up to KHR 2 million, 10% up to KHR 8.5 million, 15% up to KHR 12.5 million, and 20% for income exceeding KHR 12.5 million. Additional fringe benefits provided to employees are subject to Fringe Benefits Tax (FBT) at a flat rate of 20%, also declared and submitted monthly to the GDT.

Yes. NSSF contribution structures (such as the multi-year phase-in plan for the pension scheme), the national minimum wage (which is reviewed and set annually by a tripartite committee for the garment, textile, footwear, and travel goods sectors), and ToS progressive thresholds are subject to periodic regulatory updates. Employers are legally required to closely monitor official proclamations (Prakas) and notifications from the NSSF, the Ministry of Labour and Vocational Training (MLVT), and the General Department of Taxation (GDT) to remain compliant.

Yes. Late or non-compliant NSSF contributions attract a 2% monthly penalty interest on the outstanding balance. Incorrect or late ToS submissions to the GDT via the e-filing system trigger administrative penalties ranging from 10% to 40% of the underpaid or unpaid tax amount, plus a 2% monthly late payment surcharge on the principal tax due. Furthermore, failure to comply with mandatory minimum wage orders, NSSF business registration, or employee declaration timelines can result in severe labor law sanctions, judicial fines, or administrative closures enforced by the Ministry of Labour and Vocational Training (MLVT).

Employers can reduce payroll compliance risk in Cambodia by using a payroll system that automates NSSF contribution calculations across all three schemes, applies correct ToS progressive rates and Fringe Benefits Tax calculations, manages monthly GDT and NSSF submission deadlines, tracks minimum wage updates, and maintains complete payroll records for NSSF and GDT compliance audits.
