In the world of income tax filing the various types of income we receive throughout each year may qualify us to receive what is referred to as a tax break. It is better defined as a reduction in the amount of tax we are expected to pay on certain income(s) we have received during the year. And in the course of filing the income circumstances may sometimes contribute to a refund. The U.S. Treasury Department provides a service to allow collection of the tax. The work performed by personnel in that department, performed on our behalf; is better known as the Internal Revenue Service.
