You certainly have the choice to not send the check in -if you so desire. Probably though -your desire to stay out of jail over rules your desire to not pay taxes.
You could also, if you so desired, move to a country (if there is one) where you wouldn't pay taxes. I would say, though, that your desire to live in the good ol' U. S. of A. overrides your desire to not pay taxes.
"I desire to stay home every day to be with my family. I don't, though."
Of course, your desire to 'make a living' and thus to continue to occupy your dwelling, possess your vehicles and pay for your clothing, food and whatever else (or some other such reason) over rules your desire to 'stay at home all day. Nonetheless, you still are free to do so if your desire to do so is so great as to aleviate any concerns over those consequences. (Methinks that ultimately your desire to stay at home all day would subside once you were able to realize that objective.)
"I use my perfectly free will to go to work. As Christians, we don't desire to sin--yet we do."
I would say that every sin you did -you did because you wanted to -not because someone put a gun to your head. At least when I look at a woman lustfully, if is because I want to. Otherwise, I think your sense of sin is rather warped -ultimately why would you be blamed if your were forced beyond your will to sin?
