That's kind of an important thing to lie about (money and work related), I'd rather have someone not lying about anything at the very least on that subject. Actually, I'm editing the comment. Even lying about anything is bad because you'll eventually start lying about something work related too. That's just how it is, whether it's a time table, some interaction you had with a customer where you don't quite paint the truth or anything else. Eventually it always impacts the real world. That's the thing about the word "lying", it's not so precise. You practically mixed "omitting information" and "lying" together even though they can be extremely different in quality, depending on intent, situation and much more.
