Services
Tax time can be frustrating and we understand how confusing Canadian tax laws can be. This informative page provides links to the Canada Revenue Agency, Ontario Ministry of Finance and Niagara Region programs to help you prepare for your taxes and learn about deductions, tax credits and benefits. Carrying charges/interest expenses such as safety deposit boxes and non-RRSP investment fees.
American casinos withhold 30% of your winnings but Canadian residents can file for a gambling tax refund. CIS has been filing US Gambling Tax Recovery returns for over 35 years and has the experience to get you a refund from the IRS. We offer very competitive pricing without percentage based fees like some online services and extra tax slips and/or forms are available for only nominal fees.

Very disappointed with CIS! My husband and I were given multiple promises this year that our taxes were being 'worked on and would be completed' and after 4 months and multiple follow ups, we still have nothing! Very unfair and unprofessional especially considering this was during the off season!
After 4 years of false promises we ask you to proceed with caution!!

I always have my taxes done here. There's even an option to just put your envelope in the door slot to drop off and they will just call you when they are complete! Super easy!

Excellent. They always do a great job. They explain everything in layman's terms so I can understand and they stand behind their work if there is a problem with the CRA.

I have been coming here for the past 4 yrs. and have moved away from both NIagara Falls and St. Catharines and am temporarily living back in Toronto. Today I travelled to Niagara Falls just to have my taxes prepared by "Shirley". Wouldn't even consider going elsewhere. Thanks Shirley for your expertise as usual.

We operated our small business in Niagara for almost 10 years. We brought are taxes always to CIS. My wife would add up herself many of the expenses and calculations to ease the work required by CIS. We recently moved away but felt that we should allow CIS to handle our taxes "one more time". In short, things could have been done better. As a responsible business, if something is done wrong, you should do your best to make it right. We rushed mail our completed and signed taxes by April 24/2018. Our taxes were subsequently filed away. In JUNE, they were finally transmitted to the CRA to be processed
