No, the author of the novel is different from the artist of the manga. It's the artist that was caught for tax evasion. Apparently, it was unintentional and she just struggles dealing with her taxes lololol. Anyway, she said she already paid it all now and that this is her personal problem and has nothing to do with the manga. It's not yet certain what will happen eventually (like, if she will she continue drawing for Apothecary Diaries or not, and what punishments she may receive), since as of early June, the case was still ongoing.
Damnit i forgot the mangaka is in jail now
