IRA accounts were an important part of last week's newsletter on where to invest for retirement, but I wanted to take a deeper dive into the differences between Roth and traditional IRAs.
Both options allow for tax-deferred growth on your investments, which means that you will not pay taxes on any dividends, interest, or capital gains while your money is in the account. The primary difference between a Roth and traditional IRA is when your money is taxed.
For a traditional IRA, your money is taxed when you make withdrawals, while contributions may be tax-deductible (depending on your income and participation in an employer retirement plan). For a Roth IRA, contributions are made with after-tax dollars, but withdrawals are tax-free.
The other major difference is in flexibility. Traditional IRA owners are required to make minimum distributions (withdrawals) beginning at age 70 ½, whereas Roth IRA owners have no such requirements during the owner's lifetime. And unlike the traditional IRA, Roth IRAs allow you to continue contributing past the age of 70 ½. In short, the flexibility of the Roth IRA allows your money to benefit from additional tax-free growth.
Given the Roth's flexibility and ability to make tax-free withdrawals, it is usually the best option, but the decision isn't a no-brainer for everyone. Ultimately, choosing a suitable IRA depends primarily on an individual's time horizon as well as their current and future tax rates.
Since estimating your future tax rate is very difficult, there are a few general rules of thumb you can apply when choosing an IRA. If you expect to be in a higher tax bracket or believe that significant tax hikes could be on the horizon, then a Roth IRA allows you to "lock in" your current tax rate - paying taxes on your contributions today and not paying the higher tax rate in the future when you withdraw the money in retirement. Conversely, if you are in the top tax bracket or believe you will have a lower income tax rate at retirement, then the traditional IRA might make more sense.
Time horizon is the other big consideration. Generally a Roth makes more sense for investors that are not near retirement and thus have more time to allow their money to grow tax-free. This is a particularly important point for someone considering a Roth conversion - a hot topic recently since any investor, regardless of their income, can convert a traditional IRA to a Roth IRA this year (and last year) by paying income taxes on the amount of dollars that are converted. Investors who are near retirement may not have enough time for the tax-advantages of a Roth to offset the tax hit that comes with a conversion.
