| EVALUATION CRITERIA | THE OTHERS (Extraction-Only Tools) | K1x PLATFORM (End-to-End Tax Data Ops) |
| What you get | Extraction Tool | A secure, integrated workspace to receive, produce, and exchange private market tax data complete automation of K-1s, 1099s, W-2s, 990s |
| Outputs | XLS | Your choice: Digital .K1x file, APIs to your workpapers or other tech in your stack, integrations to 3rd party tax software like CCH & TR, XLS, or check out the partners in our K1xCollective |
| Depth of K-1/K-3 coverage | Often face page focused; limited Whitepapers/footnotes/state | Comprehensive extraction across federal + state, K-3, whitepapers, and footnotes (platform-grade for complex packages). |
| Validation & tax context | Limited validation; “data out” but user still must verify. | Context-aware compliance with validation logic aligned to tax rules—built to reduce downstream review burden. |
| Standardization | Outputs vary by source; manual mapping and cleanup required. | Standardized schema + structured data that stays consistent across entities, years, and recipients. |
| Workflow governance & auditability | Next steps happen in email/spreadsheets; limited audit trail. | Centralized workflow controls, versioning, and traceability designed for compliance and repeatability (operations, not one-off extraction). |
| Exchange & distribution | Export/import between parties; rekeying and reconciliation are | Built-in digital exchange so the right data reaches the right party fast—supports a structured digital file workflow (not just an export). |
| K-1 package production | Not designed for issuer workflows; typically outside scope. | Supports K-1 production workflows (digital packages, footnotes, allocations, statements) alongside downstream distribution. |
| 990 workflows | Usually separate tools/processes. | Streamlines IRS-certified 990 e-filings and related exempt workflows as part of the platform. Fully integrated to flow your K1s into your 990T filings & directly e-filable with IRS & state jurisdictions |
| Integrations & API | Siloed outputs; limited connectivity. | Flexible integrations + API to keep your tax data moving across systems— connected or decoupled as needed. |
| Security & compliance posture | Varies widely; sometimes unclear. | Security-forward posture (matrix emphasizes SOC 2 and 7216 compliance). |
| Best fit | Small-volume, one-off conversion needs. | High-volume, high-stakes private market workflows where speed + correctness + governance + exchange matter. |
Note: Capabilities vary by vendor. This table reflects common extraction-only limitations versus K1x’s platform approach.
