What our Customers say

I recommend Kiwitax’s Cash Flow Management services. The approach was really helpful, especially the tools to help track how we are doing based on historical data and future projections. Working out client value and the number of leads needed to convert — and seeing that in monetary terms with the tax implications, was an eye-opener. I appreciate being able to go through this process with goals attached to clear financial planning and potential outcomes. Thanks, Will 🙂

Will Roffé - Fearless Brands

You’ve made me very happy and stress free.

Thanks again.

Shane Hantler - Shine Electrical Limited

Really impressed with my first year of service with you. The follow up review was very beneficial, information provided was clear and easy to digest and provided assurance that I am tracking as well as possible in my current situation.

Great fit so far. Thanks again,

Michael Van Dinther - Mizzinc Limited

Appreciate bringing to our attention other things we could claim or include with our tax return.

Thanks 🙂

Nathan was great as was Ratheesh when he worked on our rental property accounts. Although we’ve never met in person and most of our communication is by email, the team at Kiwitax feel like real, everyday people. I love feeling like I am more than a client with a number. Jill confirmed this with her recent friendly email about my payment.
