Tax preparation software sites such as TaxSlayer have tax refund estimator calculators. Simply input the information, such as age and filing status, as prompted, and the calculator makes an estimate regarding the dollar amount owed or refunded.
Once a taxpayer has filed his tax return, he can receive updates as to when he can expect his refund to arrive, explains the official website of the U.S. Internal Revenue Service website. Refunds generally arrive 21 days after the IRS has received and processed a tax return, and the IRS website has a Where's My Refund? tool that allows taxpayers to track the status of refunds.
