[K1 Aggregator](https://support.k1x.io/k1-aggregator?hsLang=en-us) July 21, 2026 # K1 Aggregator release:  7/21/26 ## See what's new in K1 Aggregator **What's Changed:** **System performance improvements** - Increased **page load performance by over 2x** on Taxable income, UBTI, M-3, Manage Investments, State Data and Review Investments screens **K-3 Forms** - **Schedule K-3** — Part X Section 1 Lines 15, 16, and 19 are now supported end-to-end, so entered values are reflected in calculations, exports, and PDFs. **Fixes (Bugs / Stability)** **Federal Forms** - **Form 8621** — Corrected data population issues in Part I. - **Form 8865** - Fixed a printing error affecting the General Information section and address fields. - Fixed a PDF printing issue on Schedule M-1, Line 6. - **Form 926 / Form 8865** — Fixed an issue where calculated "Amount Transferred" values were not flowing to these forms. - **Schedule K-3 Export** — Export now uses country codes instead of full country names, matching the K1 Creator export format. **State Forms** - Fixed a data consistency issue that could cause State Taxable Income to be double-counted between instance-level and investment-level calculations. **Federal/State UBI** - Fixed an issue where a manually entered percentage in the "Multiply Federal By" field would disappear after being typed. **Document Upload & Processing** - Fixed an error that could prevent uploaded K-1 documents from completing processing. **Data Import/Export** - Fixed an issue where exporting investments and reimporting under "Estimate" removed existing line item breakouts. **Data Integrity** - EIN/Entity ID fields no longer pick up extraneous text and now hold only the clean identifier value. **Foreign Forms** - Fixed an issue where foreign corporation investments with a form type of "None" defaulted to an incorrect view. **Reports** - Fixed the K-1 Taxable Line Item Summary report filter so it correctly displays Activities.   - [General](https://support.k1x.io/general?hsLang=en-us#main-content) - [Account Management - SSO & Okta](https://support.k1x.io/general?hsLang=en-us#account-management-sso-okta) -
