Real estate taxes.*

Expenses that benefit only the area exclusively used for business, such as painting or repairs in the home office, are direct expenses that are fully deductible.
Expenses for keeping up and running the entire home, such as insurance, utilities, and general repairs, are indirect expenses that are deductible based on the percentage of the home used for business.
Expenses for the part of the home not used for business, such as lawn care or painting a room not used for business, are unrelated expenses that are not deductible.
The basic local telephone service for the first telephone line is nondeductible even if it is used for business. Any additional charges for long distance or a second line into the home used for business are deductible. Any deductible telephone costs are not included as business use of home cost.
