Oh I'm gonna be fucking pissed if that happens. Last year, I took on some tours that paid extra due to the extreme circumstances surrounding them, and for the first (and probably only) time, it pushed my pay to juuuuuuust above that. Like, by a couple hundred bucks. (The extra went to capping off the down payment on my house and making up for over a decade of not saving for retirement.) This year, I'm basically unemployed.
So if they look at last year's taxes to see my income and base it on that, I'm getting absolutely shit on.
