Thank you, but what about if it's a start up home business that hasn't generated any income yet?

Per IRS Pub 535 Business Start-Up and Organizational Costs: "Business start-up and organizational costs are generally capital expenditures. However, you can elect to deduct up to $5,000 of business start-up and $5,000 of organizational costs paid or incurred after October 22, 2004. The $5,000 deduction is reduced by the amount your total start-up or organizational costs exceed $50,000. Any remaining costs must be amortized."
