When this guide is useful
A contractor invoice covers built-in storage and equipment-related fixtures.
The distinction that matters
Identify the actual use, installation and relationship to the building or business equipment. A custom-built item is not automatically classified in one category.
A worked situation to investigate
A medical office build-out includes reception cabinets, general storage and cabinetry serving specialized treatment functions.
The example is illustrative. Begin with the underlying event and its source documents, then separate missing facts from disagreements about their treatment. Work through the checks below in the order that matches your file, rather than treating a completed checklist as a tax conclusion.
Build a traceable handoff
Identify the affected person, entity or property and the relevant period. Keep original evidence, corrections and the reviewer's written conclusion connected. If the facts change after review, preserve the earlier version and ask whether the change affects implementation.
