ACA Foreign Employer Addresses

The 1095 software can easily process foreign recipient or employee addresses. This article focuses on foreign employee addresses. However, the 1095 software is not designed to handle foreign employer addresses automatically. To include a foreign employer address, you must manually edit both the data file and the manifest file.

1. Edit the data file

In the data file, the 1094-C record appears first, followed by the 1095-C records. The employer address for the 1094-C is located about 5–6 lines down from the top and looks like this:

<MailingAddressGrp>
<USAddressGrp>
<AddressLine1Txt></AddressLine1Txt>
<irs:CityNm></irs:CityNm>
<USStateCd></USStateCd>
<irs:USZIPCd></irs:USZIPCd>
</USAddressGrp>
</MailingAddressGrp>

Replace it with:

<MailingAddressGrp>
<ForeignAddressGrp>
<AddressLine1Txt></AddressLine1Txt>
<AddressLine2Txt></AddressLine2Txt>
<irs:CityNm></irs:CityNm>
<CountryCd></CountryCd>
<irs:ForeignProvinceNm></irs:ForeignProvinceNm>
<irs:ForeignPostalCd></irs:ForeignPostalCd>
</ForeignAddressGrp>
</MailingAddressGrp>

Notes:

• <AddressLine2Txt> and <irs:ForeignProvinceNm> are optional.
• All other fields are required.

2. Edit the manifest file

The manifest file describes the data file you are sending. After making your data file changes, save the file.

1. Attachment Byte Size Number

This is the raw size of your ACA XML data file.

• Right-click the file → Properties → copy the file size (not “size on disk”).
• Replace the placeholder XXXXX inside:

<AttachmentByteSizeNum></AttachmentByteSizeNum>

2. CheckSumAugmentationNum

The IRS manifest also has a checksum field — often called CheckSumAugmentationNum or similar — that must match your data file.

• Typically you compute it using the IRS-approved checksum tool (they provide a SHA-256 hash generator in their AATS documentation).
• You then paste the exact value into the manifest, e.g.:

3. Save & Validate

Validate against IRS schemas (they’ll reject if the checksum or byte size is mismatched).

Save the manifest file after both updates.

<CheckSumAugmentationNum></CheckSumAugmentationNum>
