Taxes laws change every year so it best to have an accountant handle your school taxes. No matter your business structure, you should keep good records. Account for every dollar in, and every dollar out. To take advantage of all your possible tax breaks, you need to link all expenses that you may legally use to your business. This includes travel to and from the school, to your own training sessions, to demonstrations, to tournaments and camps, etc. It includes uniform costs, cleaning costs, and any meals that may be legitimately linked to business.
