For an IRA contributor who is not covered by a workplace retirement plan and is married to someone who is covered, the deduction is phased out if the couple’s income is between $183,000 and $193,000, up from $181,000 and $191,000. For a married individual filing a separate return who is covered by a workplace retirement plan, the phase-out range is not subject to an annual cost-of-living adjustment and remains $0 to $10,000. • The AGI phase-out range for taxpayers making contributions to a Roth IRA is $183,000 to $193,000 for married couples filing jointly, up from $181,000 to $191,000 in 2014. For singles and heads of household, the income phase-out range is $116,000 to $131,000, up from $114,000 to $129,000. For a married individual filing a separate return, the phase-out range is not subject to an annual cost-of-living adjustment and remains $0 to $10,000.
• Low and moderate income savers who receive a credit for their AGI (also known as the retirement savings contribution credit) will see the credit rise. It will be $61,000 for married couples filing jointly, up from $60,000 in 2014; $45,750 for heads of household, up from $45,000; and $30,500 for married individuals filing separately and for singles, up from $30,000.
