Primary sources come first
Tax, Medicare, Social Security, securities-regulation, and related claims are sourced first to the responsible government agency or regulator when an appropriate public source is available. Examples include the IRS, CMS, SSA, SEC, and FINRA.
Secondary sources may provide context, but they do not replace controlling statutes, regulations, agency publications, official forms, plan documents, account records, or professional review.
Tax years and review dates stay visible
Tax-sensitive resources identify the tax year or other effective period they discuss. Product documentation identifies the completed-return year currently supported by the scanner and distinguishes that year from later premium years or lookback years used for a limited proxy.
Published and reviewed dates describe the content version, not a promise that every future legislative, regulatory, agency, or form change has already been incorporated.
Material changes trigger a new review
A material update may be required when legislation is enacted, an agency publishes controlling guidance, thresholds or forms change, a cited source is replaced, product behavior changes, or a factual statement is found to be incomplete or inaccurate.
Formatting, spelling, and other non-substantive edits may be corrected without changing the underlying review conclusion. Material changes should update the visible reviewed date and the corresponding sitemap date.
Product behavior controls product documentation
Public documentation is checked against the current product workflow. Marketing goals do not justify stronger claims than the software, supported reference package, disclosures, and actual output can support.
The product is not presented as tax preparation, a comprehensive financial plan, an automated legal or insurance analysis, or a substitute for advisor, firm, tax, legal, accounting, investment, or insurance review.
