The Real Property Assessment and Appeals Schedule Revision Act of 2025 aims to amend Title 47 of the DC Official Code to enhance the assessment process for large-valued real properties. Key provisions include the requirement for the Chief Financial Officer to publish a list of properties that must submit income and expense information, which must be filed electronically by March 15 prior to the tax year. Additionally, property owners will be notified of proposed changes in assessed values by June 1 starting from Tax Year 2027, and the bill introduces new deadlines and procedures for appeals related to property assessments.

The bill also includes several technical amendments to streamline the appeals process, such as allowing the Office of Tax and Revenue (OTR) to send electronic responses to property owners and clarifying timelines for filing appeals and submitting supporting information. Notably, it specifies that property owners on the published list may petition OTR by July 1 and outlines the responsibilities of OTR in providing timely information to property owners during the appeal process. The changes are set to apply to tax years beginning after September 30, 2026.
