Federal and state income tax appeals
For federal taxes, the IRS Independent Office of Appeals is separate from the examination and collection functions, and it can often review a disagreement before anything goes to court. Appeals considers the hazards of litigation, so settlements there frequently reflect how uncertain each side's position is. New York State has a comparable structure: a conciliation conference through the Bureau of Conciliation and Mediation Services, or a petition to the Division of Tax Appeals, where an administrative law judge hears the case. If the administrative stage does not resolve the matter, the next step is generally a court or tribunal, and some of the deadlines to get there are strict.
Property tax assessment challenges
Many people searching for a tax appeal mean their real property assessment. In New York outside New York City, the process usually starts with a grievance filed with the local board of assessment review by a date set each year, after which many homeowners may pursue small claims assessment review while other owners proceed in court. In New York City, challenges generally go first to the New York City Tax Commission. The argument is usually about value, or about whether the property was assessed fairly compared with similar properties, and it rests on sales data, appraisals, and the details in the assessor's record.
Before the filing window closes
Every one of these paths has a filing window, and missing it can close that route, sometimes leaving only a slower or more expensive one. Bring the notice or tax bill, the envelope if the mailing date matters, and anything showing what you filed or argued before. For income tax disputes we also want the examination report and correspondence; for property, recent purchase or appraisal information and the assessor's property record card. At the outset we confirm which appeal fits, what date controls, and whether the facts support the argument you have in mind before you invest in it.
