Key Differences
The US has lower federal tax rates but you also pay state tax (0-13% depending on state), plus healthcare costs that can run $5,000-$20,000/year. When you factor in NHS vs private health insurance, the UK often works out similarly for middle earners.
Important Caveats
Tax comparisons between countries are complex. Exchange rates fluctuate, cost of living varies enormously, public services differ (NHS vs private healthcare), social security benefits differ, and pension systems aren't equivalent. Take home pay alone doesn't tell the whole story.
Tax System Comparison: UK vs United States
The US has a complex federal, state, and local tax system. Federal income tax rates range from 10% to 37%, but state taxes add 0-13% on top. There is no equivalent of National Insurance — instead, Social Security and Medicare taxes total 7.65%. The US has no NHS equivalent; health insurance is a significant additional cost ($5,000-$20,000/year for a family plan).
Cost of Living and Take Home Pay
The US generally has lower taxes but higher healthcare and education costs. A $100,000 salary in the US may seem higher than £70,000 in the UK, but after health insurance, the gap narrows considerably. Petrol, food, and consumer goods are generally cheaper in the US, while housing costs vary enormously by city.
