Hello trey and ut:

Someone will come along and move your questions...

Trey... You can file an amended return for the last three years. IF you haven't filed at all, you need to see a CPA.

Ut... If you're self employed (as you appear to be), then your income and expenses will be reported on schedule "C". Assuming that you have done your due dilligence, of course you can deduct your expenses.
