What is the difference between pension investing and regular investing?

Pensions investing offers tax advantages: contributions are often deductible from your taxable income, which means less tax needs to be paid. Also, no tax is levied on the accumulated capital. However, this money is locked up until the pension date. With regular investing, the money is freely accessible, but the tax advantage is missing. Pensions investing is therefore less flexible, but attractive if you want to build up targeted capital for later.
