I’m a US citizen that works in Canada. I have to file both countries’ tax returns. It’s a nightmare every year!

At IDM we understand how tax can be overwhelming. Be assured that our extremely skilled team wants to serve you to the highest standard ensuring you pay the least tax in both countries.

I’m a Canadian and I have a rental property and other income generated from US. The US tax system is so complicated. Help!

We have you covered. With many years or experience in helping Canadians with real estate investments in USA, we are able to offer most tax optimized strategies when filing in the USA whilst keeping your Canadian taxes in mind.

Relocating from US to Canada is overwhelming and now I have to deal with tax too. Where do I start?

You can start with us. Our top priority is to make this transition’ year of your tax returns a very seamless and positive experience for you.


What Our Clients Are Saying

Moving back to Canada from the USA after 17 years and, shortly after, starting my own company was a financial shock. We had tax responsibilities in two countries plus financial complications of running a small business. After ‘investing’ in a large accounting firm, and seeking relief, Ishali’s services were recommended to us. What a relief. Ishali advises us on tax planning, takes care of filing taxes for us, does bookkeeping and accounting for the business and allowed us to focus on business. Ishali has become a trusted friend and IDM our lifeline.
