Paycheck Calculator FAQ

Is this a payroll tax calculator?

PaystubKit estimates supported payroll-style tax lines for pay-period records. It is not a full payroll service.

Can I calculate 401(k) or insurance deductions?

Yes. Add them as user-entered manual deduction lines when they apply to your own records.

Does the calculator handle every local tax?

No. The preview focuses on supported federal, FICA, self-employment, and state income tax lines. Local taxes and special deductions may need manual handling.

Can I create a PDF from the calculator?

Yes. The same flow lets you preview numbers first and generate a paid PDF when you are ready.
