About Us

CIS Income Tax Service has been operating for more than 40 years! The company was established in 1981 by Carmen Armenti, Sophie Lewchuk, and Isabel Wilson.

Our tax preparers and reviewers collectively have decades of experience with all types of personal income tax returns. We participate in multiple annual tax update seminars and courses to ensure that we stay up to date on everchanging tax legislation. We have a strict review process in place, allowing us to guarantee the accuracy of everything we prepare.

As a testament to our quality, accuracy, and customer service, CIS has been consistently named one of the best Income Tax offices in Niagara Falls by the Readers Choice Awards, Quality Business Awards, and ThreeBestRated.

We’d like to extend our heartfelt gratitude to our many loyal clients in the Niagara Region, Halton Region, GTA, and beyond for making this possible!
