K1x Inc., the fintech company behind the industry-leading Aggregator Plus®, today announced the launch of new W-2 data extraction capabilities. This expansion makes K1x the only provider unifying unstructured and structured K-1, 1099, and W-2 data extraction in a single, patented platform, helping tax professionals eliminate up to 90% of manual entry.

Each busy season, CPA firms, corporate tax teams, family offices, and private wealth advisors spend countless hours collating K-1s, reconciling 1099s across brokerages, and keying in W-2s. Aggregator Plus® addresses this challenge by extracting both structured and unstructured data—including footnotes, attachments, K-3s, and state filings—into clean, review-ready formats.

“With Aggregator Plus, firms no longer need a patchwork of tools or late-night spreadsheet stitching,” said John LaMancuso, CEO at K1x. “By combining K-1, 1099, and W-2 automation with one-click CCH Axcess® integration, we’re helping teams reclaim time for advisory work and client conversations—where high-net-worth practices add the most value.”

Key Features of Aggregator Plus with W-2 Support:

• Comprehensive extraction: K-1 footnotes, K-3s, 199A, UBI, whitepapers, 1099s (e.g. 1099 INT, DIV, OID, B, Consolidated), and W-2 line items.
• Tabular Application Design: Seasonal views across form types for intuitive workflows.
• Instance Summaries & Reporting: Surface K-1 and 1099 income items in summarized reports, accelerating the workpaper creation and data compilation processes. Seeing all the investment income items in one place for high-net-worth individuals can unveil tax insights and opportunities buried within the data.
• Direct CCH Axcess® integration: Push clean data into returns with a single click.

By consolidating compliance into one platform, Aggregator Plus helps advisors to scale high-net-worth relationships without adding headcount, reduce error-prone manual processes, and accelerate compliance cycles.

The launch includes promotional incentives offering unlimited 1099 and W-2 automation free for one year to firms adopting Enhanced or Enterprise bundles by September 30, 2025.
