" The tax return is the form you fill out when you report your income to the IRS and pay your taxes. If you overpay, the check they send you is a refund. But every day I hear people calling the refund their "tax return, " and it's easy to understand how people could make that mistake, when they "return" your money to you. So why is the report to the IRS called a return?
