Our tax team is focused on continuous education as we work to stay ahead of changing tax legislation in the U.S. and key markets around the world.

What clients are saying about A+M

Adams + Miles helped us prepare our company for sale by structuring it in the proper way to minimize tax liabilities. It was important that we worked with them at the beginning of the process, not while the sale was happening. We tried to be proactive, and they were instrumental that way. I couldn’t have done it without them.

The partners are always available, responsive and take the time for regular check-ins. They talk to us before our annual audit to see if there is anything new happening at our organization or changes they should know about. When we amalgamated with a partner organization in 2021, we could not have done it without them.

After our recent AGM I wanted to say that Adams + Miles’ presentation was by far the best financial presentation that I’ve seen. I’ve been in the industry for over 10 years, and also a board member at my condo, so therefore I’ve seen many presentations. Yours this year was excellent, detailed, easy to follow and easy to understand.
