A tax credit differs from a deduction because it comes right off of the bottom line. A deduction lowers your gross income, which means you can calculate your taxes on a lower amount. But a tax credit is subtracted later, after you've already figured out the amount of taxes you owe. It's a dollar-for-dollar credit. Among the available tax credits is one for elderly or disabled people, one for parents who pay for child care, and one for low-income wage-earners with children. Check the list of tax credits carefully because some of them are very specialized. If you qualify for a credit, it'll probably be good news when it comes time to write out your check or calculate your refund. These tips are provided to give you general information about your taxes.
