In order to build wealth, minimizing tax liability is essential. There are only a few options for investing money on a tax-shelter basis.
Common plans are IRAs and employer-sponsored pension or profit sharing plan.
Be aware that strict IRS requirements are attached. These programs are geared towards retirement and are superior vehicles for that purpose. However, detouring from that end carry negative consequences. IRA's or Individual Retirement Account's most common advantage is contribution tax deduction. A second advantage is deferred taxes on earnings.
