Though 一旦 can be used in both formal and informal contexts, the overall tone remains neutral. It does not require additional politeness markers but should be complemented by respectful language in formal settings.

Idiomatic Expressions

An idiom that incorporates 一旦 is “一旦决定，立刻行动” (yīdàn juédìng, lìkè xíngdòng), which means "once a decision is made, take immediate action." This reflects the value placed on decisiveness in Chinese culture.
