The maximum Traditional or Roth IRA contribution for a 52-year-old man during 2015 is $6,500. A SIMPLE IRA normally allows contributions of up to $12,500, but it may allow contributions of up to $15,500 in 2015 for anyone above age 50, as noted by the Internal Revenue Service.
Contribution limits may change each year and do not apply to rollover contributions, according to the IRS. Roth IRA limits vary by filing status and modified adjustable gross income, explains RothIRA.com. Married couples filing jointly who make more than $193,000 and single people who make more than $131,000 are not allowed to participate in Roth IRAs as of 2015.
