When starting a business the selection of the GST/HST or QST reporting period i.e. how often to file your sales tax returns is often based on new business considerations. Many new business owners are quite enthusiastic and/or orderly and therefore would prefer to file their reports and pay the balance owing on a more regular basis. Conversely owners might be concentrating on the other aspects of running their business and do not want to be bothered with the administrative hassle of regular monthly or quarterly reporting. In this case, you might select the annual reporting option to make the year end reporting requirements as simple as possible. As time passes and your business evolves, you might realize that the option that you initially selected may no longer be the most optimal.
