It's a simple statement that indicates the month in which the New Year begins.
However, it's worth noting that:
* It's not the most common way to express this idea in Spanish. A more natural way to say it would be "El año nuevo comienza en enero" ("The new year begins in January").
* The sentence is grammatically correct, but it lacks context. It doesn't specify which new year is being referred to. It could be the New Year's Day (January 1st) or the start of the calendar year.
