I disagree, as this article has had a history of people trying to add irrelevant material to it (such as the costs for proper supervision). If you review Wikipedia:Article titles it says (emphasis added is my own): ": Article titles should be recognizable to readers, unambiguous, and consistent with usage in reliable English-language sources." Also "The ideal title for an article will also satisfy the other criteria outlined above; ambiguous or inaccurate names for the article subject, as determined by reliable sources, are often avoided even though they may be more common. For example, tsunami is preferred over the arguably more common, but less accurate tidal wave." Leaving it as just "Kosher tax" has proven time and again to be too ambiguous, and so per WP:COMMON I maintain that Kosher tax canard is a better proper title.
