Master Accounting and Tax Service, LLC (MATS) strives to provide the client with quality accounting, bookkeeping and business services, at an affordable cost and with the utmost integrity

We are working toward becoming a "paperless office" as well as an internet based company. We offer our clients the convenience of dealing with us strictly online. We will soon be providing all of our clients with a secure, encrypted web portal to always have all historical tax documents at their fingertips and to provide them with a secure means to transfer information to us or receive information from us.
