Consume Product

People who talk about "tax heaven" usually refer to business taxes. Those are pretty low in Switzerland, they also have the lowest VAT which is great for consumers. Unlike sales tax, VAT is only charged at the last stage, when a private consumer buys product from a business. Private-private or business-business sales are tax free.

Also, if you make so much money that you qualify for the highest tax rate, maybe it's time to start a business and invest any excess money. That way you lower your income tax and pay no tax on the money that is kept within the business.

Or you could work less, and enjoy spending more time with your family. Your wife doesn't have to work anymore, and you can feed your whole family on one 40h/week wage.
