Source Formating for Form 1042-S: A Record


Form 1042-S A Record Source Format


Generally if the Withholding Agent fails to withhold, they are personally liable for the 30% tax plus any penalties and interest.

A "Withholding Agent" is any person or other entity that has control, receipt, or custody of the money subject to withholding, or who can disburse or make payments.
Generally, the US person who pays (or causes to be paid) US source income to a foreign person must withhold 30 percent.

The Withholding Agent is similar to the "Filer, Payer, or Company" under the 1099 series forms.


A 1042 Express A Record (Withholding Agent) source record for Form 1042-S looks like this:

A|$|0|0|74-3492344|0|ABC Corporation|||P. O. Box 477||Austin|TX|NT|CA|Canada|75Q344|2006|512-344-1234|0|John Doe|Acct|512-344-1235|John.Doe@stx.rr.com


**Note that Fields 21 thru 24 are not part of the IRS "W" record, but may be printed on the 1042-T form.**


*Notes on Field3 and Field4: From the 1042-T instructions, there are 6 possible types of 1042-S that may be transmitted. They are Original, Voided, Corrected, Original pro-rata,
Voided pro-rata, and Corrected pro-rata. The voided type is gone in 2008 and after. Field3 is either Original=0 or Amended=1. Amended means the same thing as Corrected in 1099 lingo.

*Thus, each "B" source record (and IRS "Q" record) must have the same Return Type and Pro-Rata fields as the source "A" record (IRS "W" record). This is a true statement, even after 2009.

*Thus, all B records must contain the same types as the A Record. Thus, Field3 and 4 are copied from the A record to all B records in the file.
A multiple build may contain different types but must be the same for each A record. A test file will prove that this works.

*In 2009 position 810 was added to both the W and the Q records for correction codes G and C. See B record for more information.
