This is the first time I am going to attempt to right off expenses on my taxes. I made over 100k as a case manager last year and I am scared I am going to owe thousands in taxes. i was paid 25 cents a mile for most of the year so I know I can right off an additional 30 cents for each mile. Can i right off gas?? How about lunch, uniforms, cell phone bill since I wasn't reinbursed for any of it? What do you guys think??
