Filing Income Taxes for a Fictitious Name Business

[Dima Sereda]

Hi there. 

I am in the beginning stages of setting up my real estate business and have filed for an FBN to get started. I am not ready to start an LLC or an S corp at this time and will not until I have done at least a couple deals. I am not very tax literate and have never filed for anything other than a W2. How is filing them different with an FBN? How can I set myself up for success in the beginning? What can I write off? Direct mail expenses? Miles driven for work? etc... I will still be working a W2 job as well.
