Substantiq Tax · Early Access
TaxLine turns tax documents into a reviewed fact set. Confirmed facts flow into the calculation and remain linked to the source document.
How it works
TaxLine reads tax documents and proposes the facts they contain. A fact must be confirmed before it reaches the tax calculation. Missing or conflicting information keeps the return from moving forward.

It finds the tax year, form type, taxpayer details, income and deduction facts.
Confirmed facts feed the calculation rules for the selected year and stay linked to the return line.
Wrong-year documents, conflicting facts and unfinished review remain open.
One important limit: The software helps organize and check the work. It does not make an answer correct on its own. Sources, open issues and approval status stay visible.
