IRS updates specifications for filing Form 1042-S electronically

The IRS has updated the specifications for the electronic filing of Form 1042-S, Foreign Person’s U.S. Source Income Subject to Withholding. The new guidance includes numerous editorial changes from earlier guidance. Generally, the boxes on the paper forms do correspond with the fields used for the electronic file, however; if the form and field instructions do not match, the guidance in this publication supersedes the form instructions.

Electronic reporting of information returns eliminates the need to submit paper documents to the IRS. Do not send copies of paper forms to the IRS for any forms filed electronically as this will result in duplicate filing. The FIRE System can accept multiple files for the same type of return. For example, if a company has several branches issuing Forms 1042-S, it is not necessary to consolidate all the forms into one transmission. Each file may be sent separately. Do not transmit duplicate data.
