Dale is correct. One line = Long distance only that is related to business. Two lines = Deduct the entire cost of the BUSINESS line.

If you only have one phone line, you can deduct long distance calls that are for business purposes. You cannot deduct any of the expense for the local service. If you choose to add a second line for exclusive business use, that associated expenses would be fully deductible. This is applicable regardless of your business form, proprietor or corporation.
