Enter once
Allocates to every investor
Errors flagged in place
The Big Four built in-house tools to deliver K-1s faster. K1 Creator gives your firm, fund or fund admin that same speed.
K-1 season traditionally runs on re-keying.
That is where errors start.
Double entry
Data goes into Excel, then into tax software line by line. Every re-key adds time and risk.
Complex K-1 packages
Multi-state forms, complex allocations, and detailed footnotes make K-1 preparation time-consuming and difficult to scale.
Limited visibility
Without clear delivery tracking, teams spend valuable time chasing updates instead of focusing on higher-value work.
With K1x, enter the data once. K1 Creator carries it everywhere it needs to go.
K1 Creator simplifies K-1 preparation by turning partnership data into personalized K-1 packages for hundreds or thousands of investors. Manage allocations, generate applicable federal, state, and K-2/K-3 forms, customize statements and footnotes, and streamline packaging and delivery, all within one platform.

FAQ
What is K1 Creator, and who is it built for?
K1 Creator is purpose-built software for creating, packaging, and delivering Schedule K-1s for Form 1065 partnerships.
It brings the K-1 workflow into one place, including investor setup, allocations, federal and state K-1 data, Schedules K-2 and K-3, supplemental statements, and investor packages.
K1 Creator is designed for organizations that prepare partnership K-1s, including funds, fund administrators, PE-owned companies, corporations, and public accounting firms. It supports a range of Form 1065 partnership structures and is especially valuable for teams managing high-volume or complex K-1 preparation.
How is it different from the K-1 tools in my tax software?
Deadlines are fixed, but extension season never feels like enough time. Traditional tax software treats the K-1 as an output of the partnership return, so K-1s wait on everything else. K1 Creator gives K-1 preparation its own end-to-end workflow. Investors get their K-1s as early as Q1, and your partnership is less likely to be the reason they file an extension.
With K1 Creator, your team:
- Can manage allocations
- Prepare federal and state K-1 data
- Handle K-2/K-3 reporting, create supplemental statements
- Review partner-level information
- Assemble investor packages before moving the data into your tax system
K1 Creator is the only purpose-built K-1 specific creation platform that works alongside any tax software. It does not replace your tax software. It complements it by reducing the spreadsheets, re-keying, manual document preparation, and package assembly that often happen outside the tax return.
How does it change or replace my current workflow for K-1 allocations, preparation, packaging and delivery?
| Stage | Today | With K1 Creator | Benefit |
|---|---|---|---|
| Allocations | Spreadsheet schedules | Allocation codes in K1 Creator, imported from Excel or fund accounting output. | More centralized allocation management with easy to review layout. |
| Preparation | Outsourcing or tax software | Federal, state and K-3 builders. K1 Creator fills and flattens the official PDF forms. | No need to wait for the 1065 return to be complete to prepare the K-1 packages. |
| Packaging | PDFs and statements assembled manually | One package per investor with federal and state K-1s, K-3, footnotes and statements, in your order. Optional draft watermark and SSN/EIN masking. | Faster, more customized K-1 packages. |
| Delivery | Files renamed and sorted, emailed, and some printed for paper delivery | Use the included Investor Portal to deliver K-1s to investors or export single or ZIP downloads named to your convention, delivered through your current channel. | Move to a secure, easy consistent delivery method for all investors. |
| Next year | Rebuild the engagement | Rollover carries setup, people, configurations, statements and beginning capital balances forward. | Easy rollover for next year’s K-1 needs, saving you time. |
Your 1065 return stays in your tax software. K1 Creator replaces the spreadsheets, re-keying and manual PDF assembly around it.
Which tax software does K1 Creator integrate with?
Keep your tech stack. No need to change any tax technology. Supported integrations: GoSystem Tax RS and CCH Axcess Tax.
Integration support varies by form, jurisdiction, and tax year, so your K1x team can help confirm the coverage that applies to your workflow. For more information about how the integrations work, please reach out to a K1x associate.
K1 Creator complements your existing tax software. Whether you’re using tax software to prepare partnership returns or manage other tax workflows, K1 Creator provides a purpose-built solution for creating K-1 packages. Streamline the preparation of federal and state K-1s, K-2s, K-3s, and supporting statements without replacing the tax software you already rely on.
You can also use K1 Creator without replacing your existing tax software.
How does it help me catch errors before K-1s go out?
K1 Creator gives your team multiple opportunities to review and validate K-1 data before packages are finalized.
Allocation controls help identify situations where allocations do not balance as expected, and a designated rounding investor can be used to account for rounding differences. State overrides are clearly identified so users can see when state data differs from the federal amount.
Teams can also use reports such as the Capital Account Analysis to review partner information across the entity, preview statements for individual investors, and use draft watermarks to distinguish review copies from final packages.
The goal is to surface potential issues earlier in the preparation process, before they become investor-facing corrections.
How many partners or entities do I need before K1 Creator makes sense?
It depends on complexity first, then volume. K1 Creator saves time on complex K-1 packages regardless of investor count. For simple K-1 packages, the time savings become significant at 20+ investors.
Volume matters, but complexity and repeatability often matter more. K1 Creator can provide significant value when your K-1 process involves multiple states, K-2/K-3 reporting, special allocations, partner-specific statements, multiple entities, or a large amount of spreadsheet and PDF work.
Even teams with smaller partner populations may benefit when the current process involves significant manual preparation, re-keying, review, packaging, or year-over-year rebuilding.
K1 Creator is designed to help teams spend less time managing the mechanics of K-1 production and more time reviewing the tax work itself.
Do I have to wait for the 1065 return to be prepared first?
No. You can start building K-1s in K1 Creator as soon as year-end is complete, and the taxing agencies have approved the forms. You do not need to complete the entity’s 1065 return first. To use an integration, the return must exist in your tax software. GoSystem needs the return locator code, and CCH Axcess needs the return ID.
Can K1 Creator generate final K-1 packages for every partner?
Yes. K1 Creator can generate partner-specific packages containing supported federal and state Schedule K-1s, Schedule K-3 when applicable, supplemental statements, footnotes, and other supporting information.
Packages can be generated for individual investors or groups of investors and can be prepared as draft, final, or amended packages as appropriate.
K1 Creator prepares the investor-facing K-1 package, but it does not e-file the Form 1065. Filing continues through your organization’s tax software.
Can I securely deliver K-1 packages to investors through K1 Creator?
Yes. K1 Creator works with the K1x Investor Portal to provide a secure digital delivery option for K-1 packages.
Teams can monitor package activity, including whether a package has been delivered, viewed, or downloaded, helping provide greater visibility into the investor delivery process.
Organizations that prefer to use their existing portal or file-sharing process can also download K-1 packages from K1 Creator. Available options include individual files and ZIP downloads, along with controls such as SSN and EIN masking and configurable file naming.
This gives organizations flexibility to use K1x for the full preparation-to-delivery workflow or continue using their existing delivery process.
What kind of support can I expect?
You will be assigned a dedicated Client Enablement Manager who will walk with you throughout your onboarding and adoption process. K1 Creator is a relatively easy lift, with many clients working in the solution within a few weeks. Additionally, our free K1 Academy Learning Courses encourage continued growth for your team. Plus in-app assistance is available 24/7, and a live support team available to assist you along the way.
