Oman, alike the other Gulf Cooperation Council (GCC) member countries is known for tax free income for employees; therefore attracting expatriates to invest their work life here. Hence while generating the payslips through AttendHRM, there is no deduction under income tax as such in Oman for both Nationals and Expatriates. However, the social security contribution is one applicable deduction in the payroll of Omani nationals alone. The Public Authority for Social Insurance (PASI) administers the social security law in Oman.
