A certificate of deposit (CD) would be the best banking
choice when the interest rate is determined ahead of time and there is an
assurance to get back what you put in plus interest once the CD matures. If you leave the money alone during the
investment period then the bank will pay you an interest rate slightly higher
than what you would have earned in a money market or checking account. Thus,
all gains from certificate of deposits are taxable as income unless they are in
a tax-deferred (IRA) r tax-free (Roth IRA) account.
