Palestine
Taxed as ordinary income at a progressive 5-15%, with no social-security levy (the law is suspended), but there is no sovereign currency and banking is heavily restricted. Gaza's banking collapse pushed residents onto stablecoins and informal brokers, so converting USDC is the dominant difficulty.
Self-employment / business income (all realised income under Income Tax Law 8/2011), taxed at the same progressive rates as employment income; NOT capital gains.
Progressive 5-15% (annual ILS bands: 5% to 75,000; 10% to 150,000; 15% above), with a resident exemption around USD 7,200/yr.
Effectively none: the 2016 Social Security Law was suspended in 2019, so self-employed traders face no compulsory social-insurance contribution.
Self-employed file an annual self-assessment return within 4 months of year-end; the PA assesses tax in West Bank Areas A/B and Gaza, not Israeli-controlled Area C.
Legal grey area (not legal tender, unregulated), but dollar-pegged stablecoins are effectively tolerated and widely used via informal P2P money-changers; no crypto-specific tax.
