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

CIS Income Tax and Accounting Services is proud to be celebrating its 40th anniversary! The company 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.

NEW! CIS was named The Best Accountants in Niagara 2020 and 2021 from the Quality Business Awards.  We received the 31 Year Achievement Award by the City of Niagara Falls in 2012 and are 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!
