Roth IRAs are great ways to save for retirement.  While your contributions are after tax money, they grow tax free, even when you withdrawal during retirement.

This the 2009 tax year, you can contribute up to $5,000 in your Roth IRA.  The greatest advantage of the Roth IRA is all gains are tax free.  You have complete tax free growth.  The only downside is, again, you contributions are your money after it has been taxed.  The contributions are not tax exempt like your 401k.

Since the Roth uses after tax dollars for contributions, this helps you diversify your portfolio since your 401k will be taxed upon withdrawal.  Since there is no way to tell what tax rates will be like when you retire, having both a 401k and a Roth IRA gives you the best of both worlds.

One of the other benefits of a Roth IRA is you do not need to distribute your account once you reach 70 1/2 years old.  The account can continue to grow if you don’t have a need to withdrawal the funds.  So in a nut shell, you can keep your money in the tax free growth account as long as you like.

With Roth IRAs, you can also withdrawal funds without penalty, but only your contributions apply.  Only gains are penalized for early withdrawal.  Also, the funds must be held for 5 years to be eligible for withdrawal.  Example:  You contribute $3,000 to your Roth IRA that grows to $3,500.  You can withdrawal up to $3,000 (You contribution) without penalty at any time, after 5 years have past.

Roth IRAs do have some eligibility requirements though.  In order to be eligible, your adjusted gross income must not exceed $105,000 and for married couples $166,000.

For 2009, the maximum IRA contribution is $5,000 unless you are over age 50.  If you are over age 50, you qualify for contributions of up to $6,000.
