Hello, I have some questions about tax deduction. So I'm working as a private trader (toiminimi) now. I know I could deduct the rent as the working cost, but what if I work in my own property (commercial), so that I wouldn't need to pay the rent but more likely the monthly maintenance fee. Can I deduct this payment as working cost as well? And also, if I want deduct the fuel cost, does my car have to be under the name of my company?
Thank you.
