The tax benefits of this IRA are hard to beat if you have tax-exempt deployment pay. By Kimberly Lankford, Contributing Editor August 10, 2009 Is a Roth IRA a good retirement plan for a 19-year-old who is in the Navy?It definitely is. Instead of getting a tax break for contributions now, with a Roth you can withdraw the money (including earnings) tax-free after age 59½. This future tax break benefits someone whose taxable income is low now but will likely rise -- such as a young person in the military who will earn a higher salary and no longer receive a tax-free housing allowance after he leaves the military.

Your money goes in tax-free and your contributions as well as your earnings come out tax-free, a double tax benefit that's tough to beat. Another perk: You can withdraw your Roth IRA contributions at any time tax- and penalty-free for any reason. Advertisement You can contribute up to $5,000 to a Roth IRA in 2009 (people who are 50 or older can contribute $6,000) as long as your adjusted gross income is $105,000 or less, or $166,000 or less if you are married filing jointly (you can make a partial contribution if you earn $120,000 or less; or $176,000 or less if married filing jointly). You must have earned income to qualify for a Roth IRA, and combat-zone pay, which is tax-free, counts. If you earn income but your spouse doesn't, you can contribute $5,000 to an IRA in his or her name, too. You can open a Roth IRA with a brokerage firm, mutual fund company, credit union or bank. When selecting an IRA administrator, look for low fees and a range of investments choices. If you have 20 to 30 years until you plan to withdraw money in retirement (or even longer for a 19-year-old), it's usually best to invest the money in a diversified portfolio of mutual funds, especially stock funds that can grow significantly over the long run. See our suggested portfolios on the Kiplinger 25 page for some ideas based on your time frame. You have the choice of investing a lump sum or signing up to have money automatically shifted from your bank account or paycheck to the Roth IRA. Investing $416.67 per month will get you to the $5,000 annual limit. You have until April 15, 2010, to make your 2009 Roth IRA contribution. But the sooner you make a contribution, the sooner the tax-free earnings will begin to grow. Advertisement As a member of the military, you also have access to another valuable retirement-savings opportunity: the Thrift Savings Plan. Contributions to the TSP are tax-deductible now and grow tax-deferred for the future. You'll have to pay taxes on the earnings when you withdraw the money after age 59½, but you'll benefit from the current tax break and the years of tax-deferred growth. The TSP is particularly valuable because the fees are incredibly low: about 15 cents per year for every $1,000 invested. It's easy to get started -- you sign up to have money invested automatically from your paycheck -- and the minimum contribution is just 1% of basic pay each period. You can invest in both the Thrift Savings Plan and a Roth IRA in the same year. In 2009, the maximum contribution to a TSP is $16,500. Plus, if you're deployed, you can contribute all of your tax-exempt combat-zone pay, as long as your total TSP contributions for the year don't exceed $49,000. Even if you can afford to invest only a little bit now, it may be a good idea to contribute to both a Roth IRA and the Thrift Savings Plan; you'll benefit from both types of tax advantages and start a savings habit early. It's easy to increase your contributions to both types of accounts as your salary increases.
