Preposition after verb

Exempt from, in, by, as or at?

Exempt is normally followed by from to show what someone does not have to do or pay. Other prepositions may appear in separate grammatical roles, especially in passive clauses or added context.

Quick answer

Which preposition is used with exempt?

The standard pattern is exempt from something. Use from to show a duty, rule, tax, or requirement that does not apply. Other prepositions such as by, in, as, or at usually belong to different parts of the sentence rather than forming fixed combinations with exempt.

Students are exempt from the fee.
The company was exempt from local taxes.
The group was exempted by federal law.
He was exempt in certain circumstances.

Choose the pattern by meaning

These forms are not interchangeable. Choose the construction by meaning, not by which preposition appears most often.

1
exempt from + duty/rule

Showing what does not apply

Use from after exempt to name the obligation, payment, or rule that is removed.

Exempting someone from a requirement

Use exempt as a verb with an object followed by from.
