Roth IRA Contribution Eligibility. Anyone with earned income that falls under the above guidelines can use a Roth IRA to save for retirement. How much you can save is dependent upon your age. If you under the age of 50 years old you can contribute $5,500 toward retirement in a Roth IRA.
Although you can contribute to a Roth IRA during your retirement years, you cannot contribute unlimited amounts of money. The IRS enforces contribution limits for traditional and Roth IRAs regardless of age. In 2010, for example, you could contribute $6,000 if you are older than 50.
