You can open a Traditional IRA or a ROTH IRA. A Traditional IRA is tax deductible now and grows tax deferred until you take it out. Then you pay the tax on the contribution and earnings (interest etc)
A ROTH IRA you don't get a Deduction now but it grows TAX FREE so you don't pay any taxes when you take it out.
Ask your bank or go to a mutual fund company. See this IRS Publication
