“The hardest thing in the world to understand is income tax.”


Cailin Gehlsen, Owner

At Abacus on Harbour, we understand that dealing with government regulations can be daunting.


That’s why we’re here to help!

With 17 years of accounting experience (specializing in income tax and incorporation services) we understand the complex regulations and how to make them work for our clients.


We’re passionate about helping our clients grow and succeed, and we’ll stay with you every step of the way until it’s right.



Hello, I’m Cailin,

“After attending University and working 6 years for an accounting firm in the Greater Toronto Area, I’ve returned to the shores of Lake Huron where I grew up.


Following the retirement of my family’s tax business in Kincardine after 25 years, I am proud to continue to provide tax services in Kincardine and the surrounding area.


With 17 years experience in personal and business tax returns, and 7 years of progressive corporate industry experience, I have a wide breath of knowledge and experience in tax minimization, government compliance and business optimization.


When it comes to taxes or incorporation services I know the drill – and I’m here to help you every step of the way.”


Contact us today to learn more about how we can help you and your business thrive, without worry!

It's Time to Put us to Work!

Let’s Talk … 

Initial Consultation

We will start with an initial discussion to see if we will be a good fit to work together. We know how important trust is in a working relationship when finances are involved.
