Editorial reviews, calculator corrections, and source challenges are handled by the Team ToolsZila.

How corrections are handled
When a correction request concerns calculator logic, tax inputs, or source interpretation, we review the claim against the relevant official material before updating the page or data file. That process helps keep trust pages and calculator pages aligned.
