Frequently asked questions

What does this NY MPWR validator check?
It validates your XML against the official NYSDOL Certified Payroll (MPWR) schema — the same schema PayrollPenguin validates against before presenting a file as ready. It checks structure, not whether the wages themselves are correct.
Do you store my file?
No. The file is validated in your session and never stored. There is no signup and no account required to use the validator.

PayrollPenguin is a reporting and formatting tool, not a compliance guarantor or legal advisor.
