This year I’m working as an independent contractor and I’ll be given a 1099 for tax purposes. I’m an umpire for an amateur baseball association. I am absolutely required to have internet access and a cell phone.

I did not have a personal cell phone before I started with this association. Can I deduct the full cost of a cell phone if it is used only for business purposes?

I already have a personal computer and internet access at my house. However, now that it is required for a job, can I deduct the cost of the internet service? What if I buy a new computer, is that deductible as long as I keep the old computer for my personal use?

Note: I do not intend to take the home office deduction because I do not have any one particular area of my house that is designated for business use only.
