"I have worked with Madelyn Helmle of Clipper Tax Consulting on my last 2 airplane purchases. I have found that she is very knowledgeable and an expert in the rules and documentation that are necessary to get you through the process of filing for a use tax exemption with the California Department of Tax and Fee Administration."

"I feel very fortunate to have employed Madelyn Helmle and Clipper Tax Consulting for the handling of the California sales/use tax exemption on the purchase of my new Cirrus.
I have an extensive background in finance, 25 years in the investment industry, and my CPA and I would have been lost without Madelyn."
