Accuracy before speed
We prefer a smaller number of verified pages over a large number of thin or speculative pages. State revenue agencies and enacted law outrank third-party summaries.
Facts, calculations, and analysis
Reported rules are attributed to a source. Calculator outputs are estimates based on values entered by the visitor. Editorial explanations are written to clarify the source, not replace it.
Corrections
Confirmed material errors are corrected promptly. The visible source-check date is updated when the controlling guidance is re-reviewed. Substantive changes may be noted on the affected page.
Commercial independence
Advertising or affiliate relationships, if added later, will be disclosed and will not determine eligibility guidance or page rankings.
