Illinois K-1 (Form K-1-P) reports a partner's share of a partnership's income, deductions, and state adjustments specifically for Illinois state income tax purposes. These forms often include details on ordinary business income (loss), net rental real estate income (loss), interest income, dividend income, capital gains (losses), and various state-specific additions or subtractions. The inconsistent layouts and extensive footnotes across different Illinois K-1 (Form K-1-P) documents, which can vary significantly by preparer and software used, often necessitate a manual, time-consuming review process for tax professionals. Abacus addresses this challenge by accurately extracting all pertinent data points from these K-1 PDFs and normalizing them into standardized Excel workbooks. This comprehensive extraction process includes meticulously handling federal and state add-backs, applicable tax credits, and granular ownership details, thereby ensuring a clean and efficient import directly into leading tax preparation software such as CCH or GoSystem.
