Good topics for a report would be a subject that you know well. Are you a big fan of a sport or a team, do you participate in a sport, do you do a lot of cooking, are you a hanicrafter or have a hobby, do you have gardening experience, do you have a job or do volunteer work; any of these are excellent topics for a report. A topic that you know well will also be easier to write about than a topic that you have to research from scratch. The topic for an academic report would be dictated by the course that the report was for and a business report would be specified by what information the employer needed.
