Is a Smart Contract / Solidity Developer's salary tax-free in Qatar?
Yes, for expatriates. Qatar has no personal income tax on employment salaries for Qatari nationals or expatriates, so a Smart Contract / Solidity Developer earning the median QAR29K/mo takes home the full QAR 348,000 per year (QAR 29,000 per month) as an expatriate. GRSIA social insurance only applies to Qatari national employees.
