K-1 Aggregator 1099 & W2 Extraction

What is 1099 & W-2 Extraction?

The 1099 and W-2 Extraction feature in the K1 Aggregator helps you automatically detect, read, and map 1099 and W-2  tax forms—just like we already do with K-1s. This streamlines your 1040 filing process and removes the need to manually rekey 1099 & W-2 data.

Release Date:
Beta Access: June 4, 2025

Early Access: September 25, 2025

What Can You Do With It?

With 1099 Extraction, you can:

• Detect and bookmark uploaded 1099s (Form types supported: INT, DIV, OID, B, Consolidated) & W-2s

• Map line items to the correct fields on each 1099 form & W-2 form, respectively

• Upload K-1s, 1099s, W-2s in the same workflow

• Integrates into CCH Axcess: supported 1099 and W-2 forms will integrate into CCH Axcess with a one-way data integration from Aggregator into CCH (follow the data integration steps in this article before attempting integration). 

• Note: This extraction feature is currently only supported for 1040 filers.

4. Upload your 1099s for that instance.

5. The system will automatically detect 1099s and begin extraction.

6. The list will refresh as your 1099 files are uploaded, and you will be able to view the mapped data by selecting the pencil icon in the Tools column for any particular 1099 investment.

Frequently Asked Questions

Q: Can I upload multiple 1099s at once?
Yes, batch uploading is supported in the V3 Reader so that you can upload any combination of supported 1099 forms at the same time (ensure you have "Reader Release Preview" toggled on in your Manage Investments screen).

Q: CCH Integration isn’t working for 1099s and W2s.

Please revisit the articles on CCH integration set up to ensure that instance settings have been properly set up.

Please note that integration as of 9/25 will only support the “pushing over” of one investment type at a type. K1X will address the pushing over of multiples of the same investment type in the near term and will communicate this out in release notes when available. 

Q: Does it support all 1099 types?
Currently, it supports the 1099 INT, DIV, OID, and B. Consolidated 1099 support is coming soon.

Q: Is this compatible with my tax software?
CCH integration will be available 9/25/2025. Additional support for other tax software may follow based on demand.

Q: What if the extraction misses something?
You’ll be able to review and edit extracted data before finalizing.

Q: Can the data be exported out?

Not at the moment, but the team is working towards allowing for Excel exports of 1099 information. Please stay tuned for updates.
