We get this question a lot. And here is an area where you can be aggressive with your taxes. Remember, the more expenses you claim direclty against your 1099 income, the less taxes you'll end up paying.

Here is the advice I give my clients. First, make sure you can substantiate the expenses you're claiming. For the most part, that means having receipts or other documentation. For your home office, you'll need to demonstrate that you use a portion of your home exclusively for business on a regular basis.

Then, if you get audited, the IRS agent will also ask you to explain why each item you claimed against your 1099 income is related to your 1099 income. Here is where things get a little tricky. But if you can at least document that you spent the money as I mentioned in the paragraph above, you're more than halfway there.

My understanding is the IRS has gotten more aggressive in auditing returns with home office claims, esp. wrt the exclusive-use requirement. There was a true story in a finance magazine about someone losing his audit because his kid was found to be playing in his "home office" when the IRS agent came visiting.
