Our methodology
Official sources first. Plain language second.
Tax information should be traceable to an authoritative source. This preview links to IRS resources and does not fill gaps with guesses.
Source before summary
Content is intended to link directly to the responsible government source. A notice code by itself is not enough to determine a person's deadline or circumstances.
Review before publication
CP14, CP71C, CP501, CP503, and CP504 explanations are published after source checks and review. Other notice-specific explanations remain unpublished until their claims are checked and reviewed.
No individualized conclusions
The information here is general and organizational. It does not determine eligibility, recommend a tax option, or replace advice from a qualified professional.
