Those looking to get in on the benefits of a Roth IRA still have time to get one for 2007 as long as they act before the April 15th tax deadline. Setting up a Roth IRA before this deadline can also enable you to contribute the full amount for 2008 instead of having to wait until later. This is especially a great move for those just getting started as a little bit now can definitely add up in the future.

From CNN Money:
... You can still stash up to $4,000 ($5,000 if you're 50 or older) in an IRA and have the contribution count toward the 2007 tax year, as long as you do so by the April 15th tax filing deadline. Just be sure that you make it clear to the brokerage firm, mutual fund company or bank you're dealing with that the contribution is for the 2007 tax year. As long as you do that, you'll retain the option of also making a contribution for this tax year, which, by the way, can be even larger, since the ceiling for IRA contributions for the 2008 tax year is $5,000, plus an extra $1,000 catch-up contribution for anyone 50 or older.
