An accountant's job is to help you comply with business law and reporting obligations, save you time in doing so, and in general to provide advice and guidance for managing your business, with a focus on the financials.
A good accountant will get your bookkeeping and reporting done right, submitted on time, every time. They should have processes in place to ensure that deadlines are not missed, make it easy for you to provide the required information, and keep you informed about why and how your obligation are being met. All of this should be done in a manner that protects your time and saves you stress, so that you can focus your time and energy on your business.
