This tool was developed under a contract with the Internal Revenue Service (IRS). The IRS is providing this tool free-of-charge to assist withholding agents in complying with their reporting and withholding responsibilities with respect to IRS Form 1042-S (Foreign Person’s U.S. Source Income Subject to Withholding).

This tool performs a quality review of the Form 1042-S data before submission to the IRS. This tool does not in any way change a withholding agent’s obligations to file with the IRS and furnish a copy of the Form 1042-S to the payee. The withholding agent will be responsible for making any necessary changes to the data on the agent’s system of records before submission to the IRS.

The data sent to this tool will be purged after reports are generated listing possible inconsistences. The IRS will monitor use of the program and collect only demographic data for education and outreach purposes. For technical issues and questions regarding this site, please contact Fairfax Software.
