Every figure on this site is an estimate computed from published rules for a typical case. Your paycheck depends on your employer's payroll conventions, the exact forms on file, the benefits you have elected, your year-to-date wages, local rules and rounding, and the calculator can only reflect what you enter. It is not tax advice, not payroll advice and not legal advice, and it does not replace a professional or your employer's payroll department.
Known gaps
State disability and paid-leave contributions, the territories, the alternative minimum tax, most credits, reciprocity agreements and some local taxes are not modelled; the calculator lists what it leaves out and the methodology page describes the rest. Compiled figures are marked and may differ from the primary source until read there.
Comparisons
Descriptions of other calculators reflect what was read at the stated URL on the stated date. They may have changed since. They are descriptions, not ratings, and the sites described are welcome to point out anything inaccurate through the contact page; corrections are published.
