Using part of your home for business may enable you to deduct certain expenses such as:
Real estate taxes.
Qualified mortgage insurance premiums.
Deductible mortgage interest.
Rent paid for the use of property you do not own but use in your trade or business.
Utilities and services.
These expenses can be deducted to the extent your home is used as an office space. Generally, these deductions are based on the percentage of your home devoted to business use (called the “business percentage”).
