As a realtor if i have desk fees wth my broker can i still expense my home office.?

A desk fee is a payment agreement between a real estate agent and their broker. It's an alternative to splitting commissions between the agent and the broker. A real estate agent must decide whether to sign with a broker who charges a desk fee, a commission split, or some combination of the two.

You can expense a home office if you are not considered an employee of the broker. If your income is reported on a W-2, then you are an employee and cannot have a home office deduction.
