Individual Retirement Accounts
The following limits will apply to IRAs in 2018:
- The limit on annual contributions to an IRA remains unchanged at $5,500. The additional catch-up contribution limit for individuals age 50 and over is not subject to an annual cost-of-living adjustment and remains $1,000.
- The deduction for contributions to a traditional IRA is phased out for those who have modified adjusted gross incomes (AGI) within a certain range. 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 2018 AGI is between $189,000 and $199,000, up from $186,000 to $196,000 for 2017. For married couples filing jointly, where the spouse who makes the IRA contribution is covered by a workplace retirement plan, the 2018 AGI phase-out range is $101,000 to $121,000, up from $99,000 to $119,000 for 2017. For single individuals and heads of household who are covered by a workplace retirement plan, the 2018 AGI phase-out range is $63,000 to $73,000, up from $62,000 to $72,000 for 2017. 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 2018 AGI phase-out range for taxpayers making contributions to Roth IRAs in 2018 is $189,000 to $199,000 for married couples filing jointly, up from $186,000 to $196,000 for 2017. For single individuals and heads of household, the 2018 AGI phase-out range is $120,000 to $135,000, up from $118,000 to $133,000 for 2017.
