The 2001 tax act created a "saver's credit" that provides saving incentives for households with moderate income. The saver's credit provides a matching tax credit for contributions made to IRAs and 401(k) plans. The eligible contributions are limited to $2,000. Joint filers with income of $30,000 or less, and single filers with income of $15,000 or less, are eligible for a maximum 50 percent tax credit. (A 50 percent tax credit is the equivalent of a 100 percent match on an after-tax basis.)
