Individual Retirement Accounts (IRAs) allow people to save for retirement with contribution limits and rules to keep in mind at the end of the year. The maximum IRA contribution is $5,500 or $6,500 for those over 50, and both spouses can contribute even if only one has income. Exceeding the contribution limit will incur a 6% tax, but withdrawals of excess amounts can avoid this. Those over 701⁄2 must take required minimum distributions from traditional IRAs. Contributing to an IRA may qualify for the Saver's Credit which increases tax refunds or reduces taxes owed.
