Your North Carolina K-1 (CD-401S) into Excel in Minutes, not Hours.

North Carolina K-1 (CD-401S) reports an S-corporation's share of income, deductions, and state adjustments for North Carolina tax purposes. These forms frequently include complex details such as ordinary business income (loss), net rental real estate income (loss), interest income, dividend income, capital gains (losses), and various state-specific credits or modifications. The inherent variations in layout and extensive footnotes across different K-1 (CD-401S) documents, often differing by preparer and software, can significantly impede the review process for tax professionals as they manually extract and interpret data. Abacus addresses these challenges by precisely extracting all relevant fields from K-1 (CD-401S) PDFs and normalizing them into standardized Excel workbooks. This comprehensive process includes meticulous handling of federal and state add-backs, various tax credits unique to North Carolina, and detailed ownership information, ensuring a clean, accurate, and efficient import directly into leading tax preparation software like CCH or GoSystem.
