Maine Adopts Amended Rule on Controlling Interest Real Estate Transfers

AUGUSTA, Maine — Maine Revenue Services has adopted amendments to its rule governing the Real Estate Transfer Tax on controlling interest transfers, with the changes taking effect on June 30. The updated regulation, Section 18-125-207, aims to clarify the administration of the tax on complex property transactions, particularly those involving multiple related parties or phased acquisitions.

The key changes include the removal of references to repealed tax rates following 2025 legislation, updated definitions for crucial terms such as “adjusted assessed value” and “certified ratio,” and new clarifications for applying the tax to multi-transfer transactions where individuals or entities are deemed to be “acting in concert.” These adjustments are designed to provide greater clarity and ensure compliance in transactions where ownership of property changes hands through the sale of an entity rather than a traditional deed transfer.

While these amendments may seem like minor administrative housekeeping, they signal a significant tightening of scrutiny on how real estate deals are structured in Maine. For small and mid-sized businesses that own property in the state or are contemplating a merger or acquisition, this is a critical development. The clarification around “persons acting in concert” directly targets a common strategy where acquisitions are staggered over time to avoid crossing the 50% controlling interest threshold that triggers the tax. Our experience shows that such piecemeal transfers will now face a higher risk of being aggregated and taxed as a single transaction. Furthermore, the updated definitions for calculating a property’s value can lead to unexpected tax liabilities if not properly analyzed beforehand. Navigating these nuanced state tax rules is essential for any successful transaction, which is why expert guidance on mergers and acquisitions is so valuable. For businesses planning such moves in Maine, understanding these updated rules is the first step, and C&S Finance Group LLC at csfinancegroup.com can help ensure compliance and strategic planning.

Maine’s Real Estate Transfer Tax (RETT) applies not only to the direct sale of property via a deed but also to the transfer or acquisition of a controlling interest in an entity that owns real property in the state. A controlling interest is defined as more than 50% of the direct or indirect ownership in a corporation, partnership, trust, or other entity. This provision, often called the Controlling Interest Transfer Tax (CITT), is designed to prevent the avoidance of transfer taxes by simply selling the company that owns the land instead of the land itself.

The tax rate is currently $2.20 for every $500 of property value, or fractional part thereof, and is typically split evenly between the buyer (grantee) and seller (grantor). According to Maine Revenue Services, for transfers occurring on or after November 1, 2025, an additional tax will be imposed on properties valued over $1 million, indicating a legislative focus on higher-value transactions that the new rule amendments help to support.

The newly adopted amendments address several specific areas. The clarification regarding multi-transfer transactions is particularly noteworthy for investors and corporate strategists. The rule now provides a clearer framework for how the state will view a series of smaller transfers that, when combined within a 12-month period, result in a change of control. The rule provides an example where a company acquiring a 10% interest in a property-owning entity each month would trigger the tax liability upon the transaction that pushes its total ownership over the 50% mark. An amended tax return is required within 30 days of any subsequent acquisitions within that same 12-month period.

Another significant change is the updating of key definitions that determine the tax base. The term “adjusted assessed value” is now formally defined as a property’s most recent locally assessed value divided by the certified assessment ratio of the municipality. This provides a standardized method for valuation when actual market consideration is not clear or is considered nominal. This can affect transactions structured as gifts or those with complex, non-cash considerations, ensuring the tax is based on a consistent and verifiable property value.

Under the rule, any transfer of a controlling interest requires the filing of a Controlling Interest Transfer Tax Return/Declaration of Value with the register of deeds in the county where the property is located. This must be done within 30 days of the transfer that establishes the controlling interest. The tax is computed and collected by the register of deeds based on the value declared. Certain exemptions that apply to deeded transfers, as outlined in state statute 36 M.R.S. § 4641-C, are also available for controlling interest transfers but must be explicitly claimed on the return.

For business owners, investors, and legal and financial advisors, these amendments necessitate a careful review of any planned ownership changes in entities holding Maine real estate. The strengthened language around concerted actions means that informal agreements or coordinated acquisitions among related parties will likely be viewed as a single, taxable event. Proper documentation and proactive tax planning will be crucial to ensure compliance and avoid potential penalties.

Moving forward, businesses and investors with real estate interests in Maine should closely monitor the enforcement of this amended rule. How Maine Revenue Services interprets and applies the “acting in concert” provision in practice will be a key area to watch. Companies should consult with their tax advisors to assess how these changes might impact current ownership structures and future transaction strategies.
