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 extending the assessment notice and first-level appeal dates to allow for the incorporation of prior years' income and expense information into final valuations. The bill mandates that large-valued property owners file income and expense information electronically when directed by the Office of Tax and Revenue (OTR) and requires OTR to publish a list of properties that must submit this information. Additionally, it allows OTR to send electronic responses to appeals, streamlining communication between property owners and the tax office.

The bill also revises specific deadlines and procedures related to property assessments and appeals. For instance, it changes the notification timeline for proposed changes in assessed values and establishes new filing deadlines for appeals and supporting information. Notably, the amendments include provisions for electronic communication and clarify the responsibilities of both property owners and OTR during the appeals process. The changes are set to apply to tax years beginning after September 30, 2026, ensuring that the new procedures are implemented in a timely manner.
