Have you read Tax-Free Wealth yet?

How To Build Massive Wealth by Permanently Lowering Your Taxes

Tax-Free Wealth is about tax planning concepts. It’s about how to use your country’s tax laws to your benefit. In this book, Tom Wheelwright will tell you how the tax laws work. And how they are designed to reduce your taxes, not to increase your taxes. Once you understand this basic principle, you no longer need to be afraid of the tax laws. They are there to help you and your business—not to hinder you.

Finally! A tax book that lifts the veil for everyone!

My tax preparer was very impressed with the book. She knew some of the strategies in the book because she does them for her wealthiest clients. But, it never occurred to her that they also work for the working middle class who are looking to move upwards financially. I am very enthusiastic about the positive changes I am making in my financial life.

Never thought taxes could make me want to earn more money!

Tax-Free Wealth actually got me pumped with ideas on how my family could make more money and pay less taxes. Those with an entrepreneurial spirit will get pumped about Tax-Free Wealth. If you work for someone else and aren’t interested in real estate, investing, or owning your own company, don’t waste your money – this book is not for you.

Finally, the “Rich Dad” Principles Are Clear

If you feel as if you are missing a piece of the puzzle toward building wealth – then you must read this book. This book ties all the Rich Dad principles together and demonstrates how and why they work to build vast wealth over a lifetime—and beyond—for generations to come. I truly understand now why the old adage of “the rich just keep getting richer” is so true: the tax code.
