Wendy is the expert, however ...
(A) Up what is pulled out, but not too much, so you don't have to deal with it later
(B) I assume you are making more than $7K per year (is that the current number?) otherwise you don't have to pay anything
(C) I am perhaps completly 100% wrong on this, however the "MilesCam" may be a deduction -- or not -- Wendy needs to chime in
(D) In regards to (C), if you qualify for having a business, then you get super awesome deductions -- as in possibly making money and not paying any taxes
(E) Not mentioned, but move to a state that has no income tax (e.g. Washington is one)
