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.
Roth Rules. As with any government gift, the Roth IRA comes with a few strings attached. First, you can contribute to a Roth only if you have earned income from a job. Say you're in school, you're not working and you have a little extra money left over from your student loan or your parents gave you money. You cannot put it in a Roth.
