You work hard for your money.  So, why would you want to pay more in taxes than you need to?

When you enroll in a tax-advantage account to help pay for your out-of-pocket expenses, you are all ready saving money.  That's because when you use pre-tax dollars to open and contribute to your tax-advantage account, you lower your taxable income. Therefore, you will pay less in income taxes at the end of the year.
