Tax data & reporting. The records behind the forms.
Tax reporting fails upstream: missing certifications, unclassified income, entities modeled as strings. A8 Core™ keeps tax-grade records as activity happens — so forms, files, and withholding are outputs of the ledger, not a January scramble.
Form coverage
Data models and workflows per form family. Filing capability is labeled: A8 Core™ produces the data and files; transmission and filing certification run through the institution’s configured providers.
