I use my home for business. Can I deduct the expenses?
To deduct expenses related to the business use of part of your home, you must meet specific requirements. Even then, your deduction may be limited.
Your use of the business part of your home must be:
Exclusive (see *exceptions below),
Regular,
For your trade or business, AND
The business part of your home must be one of the following:
Your principal place of business,
A place where you meet or deal with patients, clients, or customers in the normal course of your trade or business, or
A separate structure (not attached to your home) you use in connection with your trade or business.
Additional tests for employee use. If you are an employee and you use a part of your home for business, you may qualify for a deduction. You must meet the tests discussed above plus:
Your business use must be for the convenience of your employer, and
You do not rent any part of your home to your employer and use the rented portion to perform services as an employee.
Whether the business use of your home is for your employer's convenience depends on all the facts and circumstances. However, business use is not considered to be for your employer's convenience merely because it is appropriate and helpful.
*exceptions
You do not have to meet the exclusive use test if you satisfy the rules that apply in either of the following circumstances.
You use part of your home for the storage of inventory or product samples.
You use part of your home as a day-care facility.
