# K1x Review: Pricing, Features, Alternatives K1x: K-1 and K-3 extraction and issuance for practices handling investment partnerships at volume. Pricing from On request, SOC 2 yes (type 2), and how it compares to the alternatives, for US accounting and bookkeeping firms. Source: https://node8.ai/accounting-tools/tax-workflow/k1x/ --- [Accounting Tools](https://node8.ai/accounting-tools/) · [Tax Workflow & Document Automation](https://node8.ai/accounting-tools/tax-workflow/) # K1x One to Watch · K1x K-1 and K-3 extraction and issuance for practices handling investment partnerships at volume [Visit K1x](https://k1x.io/) [All 26 tax workflow & document automation tools](https://node8.ai/accounting-tools/tax-workflow/) Best for Family offices, fund administrators and large firms processing hundreds of inbound K-1s a season Starting price On request SOC 2 Yes (Type 2) Multi-factor auth Unconfirmed Ownership independent Integrates with CCH Axcess, CCH ProSystem fx, ONESOURCE, GoSystem Tax RS, UltraTax CS, GruntWorx The read ## What K1x does Schedule K-1 is the specific problem, and K1x attacks it from both ends. K1 Aggregator handles the inbound side, reading K-1s, 1099s and W-2s as they arrive and producing a full digitisation plus an executive summary of the elements that drive the return. K1 Creator handles the outbound side, generating complete digital K-1 packages with allocations, footnotes and whitepaper statements across K, K-1, K-2 and K-3, covering 42 state jurisdictions. 990 Tracker is a separate line for exempt organisations, with IRS-approved e-filing for 990, 990-PF, 990-EZ, 990-T, 4720 and 8868. The write-back is the reason a tax practice would buy it rather than a general extraction tool. Federal and state K-1 data moves into CCH Axcess and ProSystem fx, and federal data into ONESOURCE, GoSystem Tax RS and UltraTax, where the UltraTax path is specifically 1065 K-1 data flowing to reduce 1040 data entry. Data-in and data-out APIs cover batch upload and structured export for firms that want to wire it into something else. GruntWorx is a named partner, its K-1 ADVANCED product handling the aggregation and organisation side. Who buys it is unambiguous. K1x cites 20 of the top 25 accounting firms, 44 of the top 100 institutional investors, more than 40,000 organisations, and a customer profile of fund administrators, wealth managers, family offices and tax-exempt organisations. Its ROI calculator is built around cycle time reduction of 55 to 65 percent and an example of 80 K-1s processed in 8 minutes. Those are volumes a small practice does not see. A three-partner firm with twenty clients holding a handful of investment partnerships each will not recover a platform fee, and no price is published anywhere, so even establishing that requires a sales conversation. What is not published matters as well. The site describes validation logic aligned to tax rules and says it is built to reduce downstream review burden, which is careful phrasing that leaves open how much human checking sits inside the service and who performs it. Turnaround is illustrated rather than committed to. The trust centre does confirm SOC 2 Type 2 with annual reports, encryption at rest, access monitoring and Azure hosting, which is a stronger posture than most tools in this category publish, but the documents themselves sit behind an access request. There is no real alternative that does the issuance side, which is the awkward part of comparing it. GruntWorx K-1 ADVANCED and SurePrep's 1040SCAN both read inbound K-1s and are far cheaper entry points for a firm whose problem is only that clients send fifteen K-1s each. Neither creates K-1 packages, handles K-3 and foreign reporting at 42-state depth, or files a 990. If the firm's problem is issuance rather than intake, K1x is effectively unopposed in this directory. One to watch stays, and as with HubSync the tier is about fit rather than track record. The install base and the patent portfolio make clear this is not an unproven product. It is a product whose economics and complexity are calibrated for institutions, and a 2 to 50 staff firm should treat it as something to know about when a client's private market activity outgrows the cheaper extraction tools.

K1x holds a SOC 2 Type 2 report. K1x does not integrate directly with a general ledger. On the tax side it works with CCH Axcess, CCH ProSystem fx, ONESOURCE, GoSystem Tax RS and UltraTax CS, which covers most of what US firms run. Beyond that: GruntWorx.
