Hey all, I looked around but I didn't see anything related to my questions.

I'm from NC and I design furniture. This is the catch. I work for a company and I also receive royalty quarterly on what I design. Of course 90% of my job is not royalty based but when I do design it's royalty based. Now, my question. what are my possibly deductions? like mileage, supplies that I use at home when I'm working there, rent from my home, etc..

let me know if I need to provide more information to better explain what I do if this is not clear.

thanks
