Cost may seem at first to be the most important question, but really it's the last question. Cost only reflects the level of service to be received in exchange for that cost.
Rather, focusing not only on what immediate services a tax professional will provide, but also on what ongoing services are available, is more important. As you and your family grow financially, so too do your tax needs. It is important that your tax professional be not only available throughout the year, but capable of growing with you and meeting your changing and evolving needs.
