～までもない

When to use it

Use ～までもない when an action is so obviously unnecessary — because the outcome is self-evident or the matter is too trivial — that taking it would be excessive. It is a standard register-raiser in reports, minutes and formal email, where 言うまでもない／申し上げるまでもない soften an assertion the reader already accepts. Distinguish it from ～ことはない (simple lack of obligation): までもない carries the nuance of "not worth going that far."

Formation

Verbs: dictionary form + までもない (言う → 言うまでもない). Polite: までもありません／までもございません.
Adverbial use: ～までもなく ("without even needing to…") links to a following clause: 確認するまでもなく明らかだ.
i-adjectives / na-adjectives / nouns: do not attach directly. Embed them in a verb phrase instead: 高いと言うまでもない, 問題だと指摘するまでもない.
Often reinforced by わざわざ, いちいち, あえて before the verb.

Examples

It goes without saying that a change to the deadline won't be accepted.
For a fix this minor, there's no need to go so far as to report it to the director.
Without even needing to call a meeting, email will suffice.
Looking at the figures, I hardly need to explain, do I?
