Are there social contributions in United States?

Yes, employees in the United States do pay social contributions, often called "payroll taxes." These amount to approximately 7.65% of your gross wages, which is deducted before you even see your paycheck. This 7.65% is split between Social Security (6.2%) and Medicare (1.45%). Social Security has an income cap, meaning you only pay it on earnings up to $168,600 for 2024. Medicare, however, has no income limit; you pay it on all your earned income, with an additional 0.9% tax on wages above $200,000 for single filers ($250,000 for married filing jointly). These contributions fund critical programs: Social Security provides retirement, disability, and survivor benefits, while Medicare covers healthcare for seniors and some younger people with disabilities. Employers also contribute an equivalent 7.65% on behalf of their employees. When budgeting for a move to the US, remember these payroll taxes come off the top, affecting your take-home pay significantly more than just your income tax bracket.
