Thomas M.
I’ve been working with Orand on my taxes even before he joined O2, and he’s consistently been outstanding. I tend to ask some complex questions, and he’s always knowledgeable, patient, and thorough in his explanations. His expertise and willingness to help make a real difference. Highly recommend!

The time I used to spend on bookkeeping and accounting now goes towards raising my children and spending time with my husband. Thank you O2!

I used O2 Bookkeeping for my personal taxes as I am a Canadian citizen but have been working in the US for the last 3 years. I have recently started a company and have been working with them to do my bookkeeping as well. They are amazing to work with!

Why Dual Citizens Must File Taxes in Both the U.S. and Canada
For dual citizens of the United States and Canada, tax season isn’t just a local affair — it’s a cross-border responsibility.
