New regulations for cadastral value disputes

New regulations for cadastral value disputes

Cadastral value is the basis on which the amount of your property tax is directly calculated. Since state valuation is carried out using mass appraisal methods, it often fails to take into account the unique characteristics of specific real estate objects. As a result, property owners – both legal entities and individuals – frequently encounter inflated figures in their tax notifications. I regularly assist clients in optimizing their tax burden through the process of disputing cadastral value. In 2026, the rules governing this process underwent significant changes. Let’s explore what property owners need to know today.

Key change: mandatory pre-trial stage

Previously, property owners had a choice – to go directly to court or to a commission. However, the procedure has now become more stringent. Most regions have transitioned to a new order, as stipulated by federal legislation.

The current step-by-step process is as follows:

Application to the Budgetary Institution (BI). This is a mandatory first step. You must submit an application to the organization that conducted the valuation.

Court Proceedings. Only after receiving an official decision from the BI (if you are not satisfied with it) can you proceed to court. Attempting to bypass the BI stage will result in the claim being dismissed.


Analysis of recent judicial practice indicates a downward trend in the number of lawsuits. However, this does not mean that the problem has disappeared. The reasons are twofold:

Improved Valuation Quality: State cadastral value is now closer to market value in most cases.

Increased Procedural Complexity: The change made the challenging process more demanding in terms of document quality.

Nevertheless, the success rate for reducing cadastral value remains stable – at around 30–40%. This demonstrates that with a professional approach, the chances of success remain high.

How to avoid the issue beforehand

There is a method known to few that is both the cheapest and most effective: challenging the value before the report is officially approved.

State budgetary institutions publish draft valuation reports on the portal of the State Cadastral Valuation Data Fund. Any right holder can review the document to identify calculation errors. If objections are submitted at this stage, the value can be adjusted before it becomes the official tax base.

As of this year, the so-called “transitional period” under Article 22.1 of Federal Law No. 237 has ended. This means that the dispute process in Moscow now operates under new rules, which have a number of legal nuances. Ignoring these specifics is the main reason why property owners spend time and resources on valuations but fail to achieve the desired result.
