Taxation of CD question

[lsbcal]

This is a simple question but I haven't found the answer explicitly stated in other sources. If you own a one year CD that matures in 2009 do you have to declare any of the interest when doing your 2008 taxes? Or is all CD interest taxable in the year of maturity?

My Vanguard account and tax documents do not state anything about interest received in 2008 so that would imply no tax due until the 2009 tax year.
