Have a Roth IRA? Here's 1 Mistake You Don't Want to Make
There's a reason so many people opt to save for retirement in a Roth IRA: Not only do these plans offer the benefit of tax-free investment gains and tax-free withdrawals during retirement, but they also don't impose required minimum distributions like traditional retirement savings plans do. And not having to remove money from your account every year gives you the option to continue enjoying tax-free growth throughout retirement.
Roth IRAs are also extremely flexible in that you can generally withdraw your principal contributions at any time without penalty. With a traditional IRA or 401(k) plan, withdrawals taken prior to age 59 1/2 are commonly subject to penalties.
