Individual retirement arrangements were introduced in 1974 with the enactment of the Employee Retirement Income Security Act (ERISA). Taxpayers could contribute up to $1,500 a year and reduce their taxable income by the amount of their contributions. Initially, ERISA restricted IRAs to workers who were not covered by a qualified employment-based retirement plan. In 1981, the Economic Recovery Tax Act (ERTA) allowed all taxpayers under the age of 70½ to contribute to an IRA, regardless of their coverage under a qualified plan. It also raised the maximum annual contribution to $2,000 and allowed participants to contribute $250 on behalf of a nonworking spouse.
The Tax Reform Act of 1986 phased out the deduction for IRA contributions among higher-earning workers who are covered by an employment-based retirement plan. However, those earning above the amount that allowed deductible contributions could still make nondeductible contributions to their IRA. The maximum amount allowed as an IRA contribution was $1500 from 1975 to 1981, $2000 from 1982 to 2001, $3000 from 2002 to 2004, $4000 from 2004 to 2007, and $5000 from 2008 to 2010. Beginning in 2002, those over 50 could make an additional contribution called a "Catch-up Contribution".
