Frequently asked questions

Is the ADP paycheck calculator accurate?

ADP says its calculators should not be relied on to calculate exact taxes or payroll. The same is true of any online estimator, including this one: your actual withholding follows your W-4 and IRS Publication 15-T.

Can employers use this calculator?

Yes, to estimate an employee's net pay. To work out the gross pay needed for a target net amount, use the gross-up calculator, and the FICA calculator for Social Security and Medicare.

Which tax year does OpenTaxCalculator use?

It defaults to 2026 IRS brackets, standard deductions and the $184,500 Social Security wage base, and you can switch to 2025.
