Israel also has a public healthcare system in practice. Mandatory participation in 1 of 4 non profit insurance programs looks like private insurance but … https://en.wikipedia.org/wiki/Healthcare_in_Israel For the health tax, wage-earners and the self-employed must pay 3.1% of their monthly salary up to 60% of the average prevailing market wage (appx. NIS 6,300 in 2020), and 5% of anything earned above it.[25] Employers are legally obligated to deduct insurance contributions from their employees' salaries, while the self-employed must arrange payment on their own. Pensioners have contributions deducted from their pensions, as do those receiving unemployment benefits. Those who are not working but have income must pay 5% of their income in health tax, while those who are not working and have no income must pay NIS 104 a month.
