It is possible for a 16 year old to start a business, but it is important to carefully consider the legal and financial implications. One potential option is to work with a parent or guardian to get set up and ensure that taxes are paid properly. Additionally, it may be helpful to discuss the respective roles around business finance with one's parents. Some popular business ideas for teens include tutoring, babysitting, pet sitting, and offering services such as lawn care or dog walking. When starting a business, it is important to research the competition and see what works in the industry. It may also be helpful to start small and scale up later if the business is successful.
