Aggregator Plus:

K-1, 1099 & W-2 Data Extraction in One Platform

Introduction

Corporate, family office, and private wealth teams all know the feeling: you’re buried in PDFs while deadlines creep closer. Aggregator Plus changes that reality by unifying K-1, 1099, and W-2 data extraction in a single, AI-powered platform—so your team spends less time keying numbers and more time advising clients.

Intro: Drowning in Documents?
Every busy season, high-net-worth (HNW) advisory firms face the same grind that eats up their hours.

  • Mountains of K-1s, often late or incomplete. Even when the face page is clean, footnotes, K-3s, and whitepaper statements arrive piecemeal, forcing tedious follow-ups and rework.
  • Stacks of 1099s across multiple custodians. Each custodian formats differently, which multiplies manual data entry and validation effort across 1099-DIV, 1099-INT, 1099-OID, 1099-B, and consolidated statements.
  • W-2s from every direction. Employee income, multi-state wages, and corrections add complexity—and increase the chance of transcription errors during peak workload.

That’s hours—sometimes days—of data entry, whitepaper chasing, spreadsheet stitching, emails and missed calls just to get to “report-ready.” It’s time for something better.

Introducing Aggregator Plus — One Platform, Three Document Types

To understand the scope, start with what Aggregator Plus processes—then see how it flows together.

  • K-1s. The platform reads face pages and the unstructured material that follows—footnotes, K-3s, 199A, UBI details, and state attachments—so you aren’t left deciphering free-form text.
  • 1099s. From 1099-DIV and 1099-INT to 1099-OID, 1099-B, and consolidated packs, Aggregator Plus normalizes formats across custodians for consistent extraction and review.
  • W-2s. Aggregator Plus supports standard PDF W-2s with line-by-line capture, making year-end wage data as searchable and reusable as any other tax input.

All three document types are extracted, digitized, and organized automatically—in one place. Built for teams managing complex clients with complex tax documents, Aggregator Plus helps accounting firms, family offices, and private wealth groups spend less time sorting PDFs and more time delivering value.

Why HNW Advisory Firms Are Making the Switch

Before switching platforms, most teams want to know what’s included and how it reduces manual work. Here’s where Aggregator Plus stands out.

Full extraction—not just face pages

To eliminate the “we’ll deal with footnotes later” trap, the platform captures the difficult parts that typically slow teams down.

  • K-1 footnotes, K-3s, whitepapers, 199A, UBI, state forms. The engine reads unstructured attachments and tax-sensitive lines, so narrative disclosures and multi-jurisdiction items are parsed, tagged, and ready for review.
  • 1099-DIV, INT, OID, B, consolidated forms. Custodian differences no longer dictate workflow; normalized extraction ensures consistent totals and cross-form reconciliation.
  • W-2s—now supported. Wage and tax details are captured automatically, reducing keystrokes and speeding up employer/employee reconciliation.

Bundled, not bolted-on

Combining K-1s, 1099s, and W-2s in one platform means your team works in a single interface, not a patchwork of tools.

  • No more stitching outputs across tools. Aggregator Plus centralizes extraction, validation, and export—so you aren’t exporting CSVs from multiple apps and reconciling by hand.
  • No more stitching outputs across time. Our ‘Partial Packets’ feature automatically stitches together fragmented K-1 information received throughout the year—organized by investment—so tax professionals don’t have to wait for every document before beginning the tedious collection process.
  • Auto-generated instance summaries. The system creates clear summaries that surface totals, exceptions, and review priorities, speeding up manager sign-off.
  • Direct integrations with CCH Axcess®. One-click pushes move clean data into your returns, shrinking prep cycles and reducing rekey risk.

More clients, fewer clicks

When you reduce manual input, capacity follows—and margins improve.

  • Eliminate up to 90% of manual input. Teams redeploy hours from copy-pasting to client advisory, planning conversations, and year-round relationship work.
  • Grow HNW relationships without expanding headcount. With data extraction handled, your staff can support more households and more entities at the same service level.

Less Tech. More Time.

Most firms supporting HNW clients use 3+ tools to cobble together tax data from investment and income documents. Aggregator Plus replaces that stack with a single experience designed by people who understand the document mess you’re in every March.

Your team wasn’t hired to key in footnotes. They were hired to advise clients, surface planning opportunities, and protect households from risk. Aggregator Plus gives those hours back—so managers review, staff learn, and clients notice the difference.
