Moving Country? How Salary Compares After Tax in UK vs US vs Canada vs Australia
Moving Country? Salary and Tax Comparison: UK vs. US vs. Canada vs. Australia
Relocating internationally is a major career milestone. However, comparing gross salaries across borders is highly deceptive. A gross salary that seems substantial in one country might yield a much smaller cash take-home pay once you account for progressive tax brackets, local state or provincial taxes, mandatory social insurance premiums, and healthcare levies.
This guide provides a side-by-side comparison of the tax burdens and retirement structures in the United Kingdom, United States, Canada, and Australia for the 2026 tax year.

Core Deductions & Benefits Compared
1. Healthcare Funding
- United Kingdom: The NHS is publicly funded through general taxation and National Insurance Contributions (NIC). Deductions are automatic, with no additional private premiums required for care.
- United States: FICA Medicare (1.45% plus 0.9% surtax) only funds care for seniors. Working expats must typically purchase private health insurance, which can be deducted pre-tax but carries high out-of-pocket costs.
- Canada: Universal healthcare is administered by provinces and funded through provincial and federal income taxes.
- Australia: Medicare is funded by a mandatory 2.00% Medicare Levy on taxable income (waived for low-income earners).
2. Retirement and Pension Savings
- United Kingdom: Auto-enrolment workplace pensions require a minimum 8% contribution (typically 5% employee, 3% employer). Tax relief is immediate.
- United States: Traditional 401(k) contributions are pre-tax and capped at $23,500 for 2026.
- Canada: Registered Retirement Savings Plans (RRSP) are pre-tax, with limits up to $32,490 for 2026. CPP is a mandatory payroll tax.
- Australia: The Superannuation Guarantee (12.0%) is paid by employers into a super fund. Contributions are taxed at a flat concessional rate of 15% inside the fund.
