Is a Embedded Systems / IoT Engineer's salary tax-free in Saudi Arabia?
Yes, for expatriates. Saudi Arabia has no personal income tax on employment salaries for Saudi nationals or expatriates, so a Embedded Systems / IoT Engineer earning the median SAR16K/mo takes home the full SAR 192,000 per year (SAR 16,000 per month) as an expatriate. GOSI social insurance only applies to Saudi national employees.
