Are social contribution rates the same for all income levels in these countries?
No, rates vary significantly. In the UK, National Insurance Class 4 has different rates for lower and upper profit bands. Ireland's USC has multiple bands, and Australia's Medicare Levy is a flat 2%, but there are exemptions for low incomes. New Zealand's ACC levy has an income cap.
