Frequently asked questions
- Who pays payroll tax — me or my employer?
- Both. Employees and employers each pay an equal share of Social Security and Medicare. Self-employed people pay both halves themselves as self-employment tax.
- Why does Social Security stop at a wage base?
- Social Security benefits are capped, so the tax that funds them is capped too. Once wages pass the annual wage base, no further Social Security tax is owed, though Medicare keeps applying.
- Does this include unemployment taxes?
- No. FUTA and SUTA are employer-only taxes on a separate, lower wage base and vary by state. Add them separately if you need total employer labor cost.
