[3] Boronia imlayensis was first formally described in 2003 by botanist Marco Duretto in the journal Muelleria from specimens he collected on a Mt Imlay ridgetop in 1995.

Within this, it belongs to a group of 25 species of pinnate-leaved boronias from southeastern Australia, many of which have restricted ranges.

Its relatives include B. citriodora, B. gunnii, B. latipinna, B. muelleri, B. pinnata, B. rivularis, B. safrolifera and B.
