For the most part, IRAs are treated like 401K’s and SEPs in that the money you put into the plan is exempt from taxes when it is invested, but you do pay tax on it whenever it is withdrawn. Since the tax is deferred until you withdraw, these are typically referred as tax deferral vehicles for retirement.

With an IRA, you must leave the money invested in the IRA until you reach the age of 59 ½ or face a 10% early withdrawal penalty on top of the tax, and you must begin taking a minimum distribution each year from an IRA at the age of 70 ½ .

There are limits to the amount you can make contributions that are exempt from taxes in any year. For 2008, this limit is $5,000 for taxpayers under the age of 50, and $6,000 for those who are over 50. It is usually unwise to contribute more than this to an IRA as excess contributions made in after tax dollars, and they will also be taxed on withdrawal.

The Roth IRA works just the opposite. Contributions to a Roth IRA are always made in after tax dollars, that is, the contributed amount is not exempt from tax. However, provided the appreciation in the account is not taken before the age of 59 ½ , none of the amount withdrawn is ever taxed. Thus, if you invest $5,000 in a Roth IRA for 20 years ($100,000 total), until age 60, and it grows to $500,000 during that time, under the law, you will never pay tax on the withdrawals from this account.

One thing that has always concerned me with respect to Roth IRAs is that a day may come when Congress decides this is too much of a sweetheart deal and begins to tax “excess withdrawals” or withdrawals made by “the wealthy”. Obviously, if you’re investing in a Roth, you’re hoping it will grow as much as possible and that you become wealthy yourself. So look out – it hasn’t happened yet, but there are no guaranties that any tax break will last forever.
