CIS Income Tax and Accounting Services was established in 1981 by Carmen Armenti (current owner/operator), Sophie Lewchuk, and Isabel Wilson. Many of our dedicated employees have been with the company for more than 25 years.

CIS was awarded the 31 Year Achievement Award by the City of Niagara Falls in 2012 and is currently rated as one of the best tax services in Niagara Falls. We’d like to extend our heartfelt gratitude to our many loyal clients in the Niagara Region, Halton, and GTA throughout the years for making this possible!
