About USNetPay

USNetPay answers one question well: how much of your pay you actually keep.

What we do

We build paycheck calculators for each U.S. state from the official withholding publications: IRS Publication 15-T for federal tax, and each state's own tables for state and local tax. Every page lists its sources and the date we last checked them.

How we keep it accurate

• We implement the same percentage methods payroll software uses, not approximations from tax brackets.
• Automated tests check our engine against the worked examples in the official publications before each release.
• We review every rate each January and whenever a state changes its tables mid-year.
