Is a Smart Contract / Solidity Developer'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 Smart Contract / Solidity Developer earning the median SAR27K/mo takes home the full SAR 324,000 per year (SAR 27,000 per month) as an expatriate. GOSI social insurance only applies to Saudi national employees.
