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.
If that is your only source of income, you are not eligible to contribute to a Roth. However, if you are married and your spouse has a job, you can contribute up to $5,000 to a spousal Roth IRA($6,000 if you are age 50 or older) assuming your spouse earned at least that much for the year of your contribution.
