Ok, I pretty much think I'm getting a better idea on all this. Just one more question. As far as receipts go, If I go to wal-mart, buy a computer desk, curtains, a toilet seat, but also buy work relates stuff such as pens, tablets, gloves, etc, all this stuff is gonna be on the same receipt obviously. Should I highlight or circle the work related stuff, or just not worry about it and basically just make sure I keep the receipt.
BTW, I am a company driver.

 

If you use the toilet seat, curtains and other items you listed in your work, they are deductible. If not, then they are not legally deductible on your taxes as a work related expense. It doesn't matter if they are on the same receipt or not. Unless it is used in the performance of your job, then it isn't deductible. It would be better to pay for the items separately to keep your records straight.
