Wisconsin K-1 (Form 5S or 5K-1) reports a partner's or shareholder's share of a pass-through entity's income, deductions, and state adjustments for Wisconsin tax purposes. These forms often contain specific Wisconsin modifications and adjustments, such as those related to decoupling from federal provisions, state-specific additions or subtractions, and various state tax credits. The inconsistent layouts and extensive footnotes across different Wisconsin K-1 (Form 5S or 5K-1) documents, which can vary significantly by preparer and software, often lead to considerable delays in the review process for tax professionals. Abacus mitigates these challenges by extracting all pertinent fields from K-1 (Form 5S or 5K-1) PDFs and standardizing them into structured Excel workbooks. This process includes precise handling of federal and state add-backs, applicable tax credits, and granular ownership details, ensuring a streamlined and accurate import directly into tax preparation software like CCH or GoSystem.
