CIS storefront

Our mission is to get you the best tax refund possible and provide bookkeeping services for businesses in an efficient and accurate manner.

CIS was established in 1981 and is locally owned and operated by Carmen Armenti. Many of our dedicated staff members have been with the company for over 25 years and are experienced in all types of returns. During the busy tax season, no appointment is required and you can be assured of short wait times to sit with one of our several knowledgeable tax professionals. We’re open year round to serve all your bookkeeping and tax service needs.

We’d like to extend our heartfelt gratitude to our many loyal clients in Niagara Falls, St. Catharines, Thorold, Welland, Fonthill and Fort Erie throughout the years!

CIS Income Tax Service was awarded the 31 Year Achievement Award by the City of Niagara Falls in 2012.
