"Lisa did some work for us on some tax issues that proved to be very beneficial to DEE (Downeast Energy). She recovered a substantial amount for our company. We were so pleased with the results that we engaged her for additional tax work following her first project. She is very professional, knows the laws pertaining to our industry, and knows her way around the Maine Revenue Services arena!"

John Peters, President (Retired)


Michael helped us with a review of our property tax returns. Despite my initial skepticism I figured I would give it a shot since there was nothing to lose except a little time gathering documents for review. It turned out to be the right call, Michael saved us thousands of dollars and the whole process was very painless.  I would highly recommend Taxabilities services.
