No. A tax credit is a dollar-for-dollar reduction in what the taxpayer owes. That means that a taxpayer who owes $8,000 in income taxes and who receives an $8,000 tax credit would owe nothing to the IRS.

A tax deduction is subtracted from the amount of income that is taxed. Using the same example, assume the taxpayer is in the 15 percent tax bracket and owes $8,000 in income taxes. If the taxpayer receives an $8,000 deduction, the taxpayer's tax liability would be reduced by $1,200 (15 percent of $8,000), or lowered from $8,000 to $6,800.
