A tax appeal is a formal request made by a taxpayer to challenge the amount of tax assessed by a tax authority, such as the Internal Revenue Service (IRS) in the United States. Taxpayers may believe that their property value, income, or deductions have been incorrectly evaluated, leading to an unfair tax burden. The appeal process allows them to present evidence and arguments to support their case. During a tax appeal, the taxpayer typically submits documentation and may attend a hearing to explain their position. The tax authority will review the appeal and make a decision, which can result in a revised tax assessment. If the taxpayer is still unsatisfied, they may have further options, such as seeking judicial review.
