retroacting

Taking effect earlier

Retroacting is applying or taking effect backward in time.

Laws or policies that retroact reach back to cover situations that existed before their enactment: The tax increase retroacts to January 1.

The word is less common than its adjective form retroactive, but carries the same sense of working in reverse chronological direction.
