President Clinton and Congress have agreed to a tax cut that will add a $500 dollar tax credit per child. This credit, according to tax analysts at Deloitte and Touche, will benefit working single mothers. Under the current system, a working mother with two children and an income of $20,000 per year would receive a $771 tax refund . This refund comes from the Earned Income Tax Credit, a credit designed to create incentive to work in low-wage jobs. Under the new agreement, the same working mother will receive an additional $500 per child, for a total of $1,771. The tax cut will also benefit middle-income households with children under 17 or in college, and families with substantial capital gains investments.
