K-1 Aggregator Reader: 1099 and W-2 Extraction
Explains how 1099 and W-2 forms are processed and extracted in K1x.
K-1 Aggregator Reader supports automated extraction of 1099 and W-2 forms using the same upload and processing workflow as K-1s. This allows firms to upload documents once and extract structured tax data without manual keying.
This article explains what 1099 and W-2 extraction includes, how it works at a high level, and what to expect after upload.
K-1 Aggregator Reader: 1099 and W-2 Extraction
K-1 Aggregator Reader supports automated extraction of 1099 and W-2 forms using the same upload and processing workflow as K-1s. This allows firms to upload documents once and extract structured tax data without manual keying.
This article explains what 1099 and W-2 extraction includes, how it works at a high level, and what to expect after upload.
How 1099 and W-2 extraction works
When you upload 1099s or W-2s into K1 Aggregator, Reader automatically detects the document type and extracts the available data.
-
No additional setup or configuration is required
-
Uploading follows the same process used for K-1s
-
Extracted data is available for review and downstream use after processing
You do not need to select a form type during upload. Reader identifies the document automatically.
W-2 extraction
W-2 extraction is intentionally simple.
All populated boxes on the W-2 are extracted automatically.
If a box appears on the form and contains data, that data will be included in the extracted results.
There are:
-
no special rules,
-
no form-specific configuration,
-
and no differences in workflow compared to other Reader-supported documents.
If a box is blank on the W-2, it will not appear in the extracted data.
1099 extraction
Reader supports extraction of commonly used 1099 forms, including:
-
1099-INT
-
1099-DIV
-
1099-OID
-
1099-B
-
Consolidated 1099 statements
Reader extracts the populated boxes present on each form. The specific boxes available depend on the 1099 type and how the issuer prepared the document.
Reviewing extracted data
After processing:
-
Extracted 1099 and W-2 data can be reviewed within K1 Aggregator
-
Users can make adjustments if needed before using the data downstream
The review experience is consistent with other Reader-extracted documents.
Using extracted data with tax software
Extracted 1099 and W-2 data can be used with supported integrations (such as CCH Axcess), following the same general integration workflows used elsewhere in K1 Aggregator.
Details about how extracted data maps into specific tax software are covered in the relevant Integration articles.
What to expect (and what not to expect)
-
Reader extracts data based on what is present on the document
-
Issuer formatting and content can vary across forms
-
If a form does not contain a value, Reader cannot infer or generate it
Reader prioritizes accuracy and consistency over inference.
