I am a DJ and traveling to San Francisco for a DJ event. I am leaving Saturday and returning on Monday. Event is Sunday. What can I write off? Flight, Hotel, Meals?

Since you are self-employed and are travelling for a job, all of the expenses--food, travel, lodging--are deductions that would be reported on your Schedule C or C-EZ.  Make sure you have the receipts and that the trip is solely for the purpose of work.
